Abstract:

¹⁵Oxygen positron emission tomography (¹⁵O PET) has been used to demonstrate ischaemia and define physiological thresholds predictive of tissue viability in stroke. Unfortunately, it is difficult to translate such data to clinical head injury due to concurrent use of sedative agents, the metabolic effects of trauma, and the lack of a priori knowledge regarding the location of ischaemia. While ischaemia may be prominent in perilesional areas, it may also be observed in structurally normal brain. The methodological basis of ¹⁵O PET is discussed with consideration of the steady-state ¹⁵O model. These studies utilised phantom and control data to address the processing of imaging datasets, the precision of repeated measurements in interventional studies and the reliability of voxel-based measures of ischaemia. The methodology developed in these studies was used as a basis for the experimental work in patients. Head injured patients within 24 hours of ictus, showed evidence of regional ischaemia that was not detected by common bedside monitoring techniques, such as jugular bulb oximetry. Although the absolute volume of brain at risk was variable, it had important implications in terms of outcome. Evidence of an increased gradient for oxygen diffusion and impaired oxygen unloading were associated with structural evidence of microvascular collapse and perivascular oedema. This suggests that mechanisms other than simple perfusion-limited ischaemia may be responsible for tissue hypoxia in head injury. Moderate hyperventilation increased the volume of brain at risk of ischaemia injury, both by reducing perfusion, and by increasing oxygen demand. Brain regions that were unable to increase oxygen extraction to meet increased oxygen demand showed a fall in cerebral metabolism. Elevation of cerebral perfusion pressure above 70 mmHg does not benefit the injured brain in the absence of significant cerebral ischaemia.

Abstract:

Health professionals as well as families are being confronted with long-term care and caregiver issues that accompany the increasing incidence of individuals surviving traumatic brain injury. A sample of parents and brain-injured offspring from 20 families served as informants. The purpose of this study was to identify a qualitatively generated theory describing the parent's experience following a brain-injured child's return to the home setting. An exploratory qualitative design using grounded theory methodology was used during data collection and analysis. All the brain-injured offspring had survived a moderate-to-severe traumatic brain injury; were living with at least one parent; and were ages 17 to 34. A three-phase theory, Investing in the Comeback, was generated using grounded theory methodology. The theory's three stages, centering on fostering independence and seeking stability, describe the work of the parent living with a brain-injured offspring. The first phase, Centering On, involves the parent's focusing attention and behavior primarily on the brain-injured offspring. During Fostering Independence, the second phase, the parent initiates and maintains efforts to promote the offspring's resumption of independent functioning. The final phase, Seeking Stability, consists of the parent working to establish a regime that maintains the brain-injured offspring's optimal performance, while minimizing the strain on other family members. Theoretical sampling guided the identification of categories, properties, conditions, and consequences of each phase. Four quantitative measures supplied descriptions of sample characteristics and included demographics, cognitive deficit ratings of the child by the parent and the investigator, and the parent's perception of the family's functioning.

Abstract:

It has been well established that ischaemia can result in secondary injury to the brain following trauma. While such ischaemia has been imaged, it has been difficult demonstrate its physiological significance. The aim of this research was to use diffusion weighted magnetic resonance imaging (DWI) to characterise the patterns of cytotoxic and vasogenic oedema early after head injury and correlate changes with regional physiology, imaged using 150 positron emission tomography (,sO-PET). Data from methodological developments carried out in the course of this research are presented These include the testing of MR compatibility of infusion pumps, optimisation of image processing routines, assessment of the validity of commonly used MR measures of tissue injury in the context of head injury, and an assessment of the test-retest reproducibility of DWI. Early DWI imaging in 30 patients with significant head injury (range 8 - 134 hours) revealed a characteristic contusional morphology, with a haemorrhagic core and concentric rings of vasogenic and cytotoxic oedema. In the regions studied, the integrated volume of pericontusional oedema was over three times the volume of the central core. An analysis across patients, although confounded by interindividual variation, suggested that this pericontusional oedema increased in size with time from injury. Correlation with electron microscopy suggested microvascular ischaemia as a mechanism for these changes The physiological correlates of the ADC changes described above were investigated in a subset of nine patients with ,sO-PET. The contusion core showed significant reductions in cerebral blood flow (CBF), oxygen extraction fraction (OEF) and cerebral oxygen metabolism (CMR02), while the region of vasogenic oedema only showed significantly reductions in CMR02. Other studies explored the use of dynamic DWI to assess the impact of hyperventilation on ADC changes around contusions. The implications of these findings are discussed and further research directions explored.

Abstract:

There is a high incidence of head injury in children, yet few studies have systematically studied cognitive outcome. This study was designed as a survey to (a) establish the nature of intellectual and neuropsychological deficits that occur after head injuries of differing severity in children aged 6 to 14 years, (b) establish the nature of recovery curves in the first year after injury, and (c) determine which medical and psychosocial factors are associated with poor cognitive outcome and which functions show persisting impairment. From 1134 children admitted with head injury to Red Cross and Groote Schuur Hospitals during a 2-year period, a consecutive sample of all those who had post-traumatic amnesia (PTA) over 1 hour, a compound depressed or basal skull fracture, a seizure, or any evidence of neurological involvement, was collected (n=388). Further requirements that they should be between 6 and 14 years, English or Afrikaans speaking, and have no history of significant cerebral pathology or mental retardation, reduced the sample to 123 children. Severity groups were formed according to the length of PTA: 56 moderates (PTA less than 1 day), 40 severes (PTA 1 to 7 days), and 28 very severes (PTA more than 7 days). They were matched for age, sex, socioeconomic status and ethnic group with 46 controls who had traumatic injury not involving the head. Detailed accident, medical and psychosocial data were collected. The children were assessed on a battery of tests covering intelligence, language, motor speed, visuographic and memory functions, as soon as they were out of PTA (Tl), 3 months later (T2), and at 1-year post-injury (T3). The 4 groups are compared at each interval on Tukey' s studentized range test and the extent of recovery within and between the groups is compared by repeated measures analysis of variance.

Abstract:

The aim of this dissertation has been to assess the effectiveness of computer aided repetitive practice at certain attentional tasks, in pursuit of enhancing attention among head injured subjects. The last fifty years has seen a momentum gathering in the area of brain injury rehabilitation and in recent decades, greater emphasis has been placed on the assessment and retraining of attentional disturbances. Drawing on the ideas of the British Neurologist, John Hughlings Jackson, Zangwill (1947) suggested that rehabilitation could assist higher levels of executive control within the organism to develop compensating strategies to partially overcome the manifestations of lower level disruption. This thesis uses the hierarchical model of attention provided by Shiffrin and Schneider (1977) as a framework within which to explain the functioning of attention, and to understand the deficits of attention which can arise as a consequence of head injury. There is evidence to show that deficits of phasic arousal, signal detection, and speed of information processing are common among the head injured population. A number of studies have been unsuccessful in realizing improvements in attention as a result of four weeks cognitive retraining, but it is argued that this lack of success is due to an inadequate period of training. Using groups of head injured subjects, this study attempted to retrain aspects of attention in 55 hours of training conducted over three months. In addition, some subjects in the first experimental procedure took a maintenance dose of Methylphenidate, a CNS stimulant, in order to study the effect of combining such medication with attentional retraining. Results indicated that three months of computer assisted retraining produced improvements in attention, while one month of such training was not successful. The introduction of Methylphenidate had no therapuetic effect.

Abstract:

Young adults are more likely to suffer blast injury and traumatic brain injury (TBI) than other age groups. This article reviews the literature on the vestibular consequences of blast exposure and TBI and concussion. In addition, the vestibular test findings obtained from 31 veterans with a history of blast exposure and/or mild TBI are presented. The authors discuss loss of horizontal semicircular canal function and postural instability related to head injury. Preliminary data suggest the novel theory that otolith organs are uniquely vulnerable to head injury and blast exposure.

Abstract:

This study is an investigation of closed head-injured (CHI) children's ability to assign thematic roles to nouns in sentences of varying syntactic structure. Seven CHI children, aged 9 to 15 years, participated as subjects. All subjects were at least two months post-onset and demonstrated symptom stabilization. The procedure replicated a task designed by Caplan, Baker and Dehaut (1985), which requires that subjects enact orally presented sentences by manipulating toy animals. Four questions were addressed: 1) Is the assignment of thematic role more difficult in some sentence structures than in others for closed head-injured and normal children? 2) Do CHI children have more difficulty assigning thematic role than do normal children? 3) Are any particular sentence types relatively more susceptible to interpretation breakdown than other sentence types? 4) Does the pattern of sentence interpretation breakdown in CHI children resemble that found in CHI adults and aphasic adults? The closed head injured subjects as a group produced more errors than the age- and sex-matched controls. Futhermore, some sentence structures were more difficult to interpret than were others for both head injured and control subjects. The hierarchical order of difficulty for both groups was similar to the order found for adult closed head injured patients and adult aphasics. Several syntactic structural features -- noncanonical word order, presence of a third thematic role, and presence of a second verb — were shown to influence sentence complexity. These features affect syntactic interpretation by brain injured subjects regardless of etiology. The results of this study suggest that strategies used for sentence parsing are similar across brain injured populations, regardless of age.

Abstract:

Head injuries are a major health concern for sport participants as 90% of emergency department visits for sport-related brain injuries are concussion related (Canadian Institute for Health Information, 2016). Recently, reports have shown a higher incidence of sport-related concussion in female athletes compared to males (Agel et al., 2007). Few studies have described the events by which concussions occur in women’s hockey (Delaney et al., 2014, Brainard et al., 2012; Wilcox et al., 2014), however a biomechanical analysis of the risk of concussion has not yet been conducted. Therefore, the purpose of this study was to identify the riskiest concussive events in elite women’s hockey and characterize these events through reconstructions to identify the associated levels of peak linear and angular acceleration and strain from finite element analysis. 44 head impact events were gathered from elite women’s hockey game video and analyzed for impact event, location and velocity. In total, 27 distinct events based on impact event, location and velocity were reconstructed using a hybrid III headform and various testing setups to obtain dynamic response and brain tissue response. A three-way Multivariate Analysis of Variance (MANOVA) was conducted to determine the influence of event, location and velocity. The results of this study show that head-to-ice impacts resulted in significantly higher responses compared to shoulder-to-head collisions and head-to boards impacts however, shoulder and boards impacts were more frequent. All events produced responses comparable to proposed concussion threshold values (Zhang et al., 2004). This research demonstrates the importance of considering the event, the impact characteristics, the magnitude of response, and the frequency of these impacts when attempting to capture the short and long term risks of brain trauma in women’s hockey.

Abstract:

A differential diagnosis between head injury and depression is critical to ensure proper treatment and appropriate interventions. Knowledge about this can only aid counseling psychologists' work with this population and, identifying a measure that can assist in this process is essential. The purpose of this study is to measure the utility of the Dean — Woodcock Neuropsychological Assessment System (D-WNAS) in distinguishing individuals with head injury from those who have a primary diagnosis of depression, and general neurological impairment. Participants included 433 adults (222 males, 211 females) between the ages 20-55 years of age (mean = 35.3 years, SD = 10.97 years) from the Midwestern United States. During the individual's treatment in the neuropsychological laboratory, each person was administered the following: the Dean-Woodcock Structured Interview (Dean & Woodcock, 1999), mental status exam, the Woodcock Johnson — Revised Tests of Cognitive Ability (WJ-R COG; Woodcock & Johnson, 1989b), the Woodcock Johnson — Revised Tests of Achievement (WJ-R ACH; Woodcock & Johnson, 1989a), and the Dean-Woodcock Sensory Motor Battery (DWSMB; Dean & Woodcock, 1999). This study indicates that responses to D-WNAS can be used to reliably classify adults into groups of depression, head injury, and general neuropsychological impairment. In particular, responses to the D-WSMB portion of the D-WNAS can be used to reliably classify adults into groups of depression, head injury, and general neuropsychological impairment. Classification results revealed that the original grouped cases were classified with 62.6 % (p < .001) accuracy and with 73.2% overall accuracy when the head injury and general neurological impairment groups were combined and compared to depression and normative groups. The WJ-R COG and WJ-R ACH were not as reliable as the D-WSMB at predicting group membership.

Wainman-Lefley, Jessica. "Allostatic load and heterogeneity of outcome after head injury." Thesis, University of Glasgow, 2017. http://theses.gla.ac.uk/7931/.

Full text

Abstract:

Background: Outcome after head injury is heterogeneous; in particular, late outcome including disability and increased risk of mortality are only partly explained by the severity of the injury and demographic factors (McMillan et al., 2014; McMillan et al., 2012; Whitnall et al., 2006). The allostatic load model conceptualises how stressors can chronically elevate physiological activity and impact on health (McEwen, 1998b). Allostatic load has been shown to be associated with psychosocial functioning, morbidity, and mortality and can predict these outcomes at follow-up; however, it has never been investigated with outcome in the head injury population. The studies in this thesis explore the extent to which allostatic load is associated with cognitive and disability outcome, and change in disability over time after head injury. Methods: A systematic search was conducted to inform how to measure allostatic load; 15 indicators of health were assessed representing immune, cardiovascular, anthropometric, metabolic, and neuroendocrine system functioning, and were combined using a summation z-score method to create allostatic load scores. Four empirical studies were conducted to investigate the relationship between allostatic load and outcome after head injury; at discharge from hospital in severe head injury participants (n = 35), at 6 month follow-up (n = 28), late (median 27 years) after head injury (n = 41), and late after repeat concussion in retired international rugby players (n = 48). Allostatic load was also compared with cognitive function late after head injury and repeat concussion and with change in disability between hospital discharge and 6 month follow-up, and from 6 months post-discharge to late after injury. In all the studies, the allostatic load scores of head injury participants were compared to that of non-head injured comparison participants. Results: The studies within this thesis found limited evidence to suggest that allostatic load was associated with outcome after head injury. There was no association between allostatic load and disability outcome, change in disability over time, or cognitive function in the severe head injury studies. There was a significant relationship between higher neuroendocrine component scores at hospital discharge and worse disability outcome at 6 month follow-up, indicating possible pathophysiological consequences of neuroendocrine indicators early after injury. Also, the finding that head injury participants had higher anthropometric and metabolic component scores than comparison participants late after injury, and that greater disability over a median of 27 years was associated with higher metabolic component scores, indicates that brain damage causes an increase in secondary outcomes of allostatic load, which potentially has implications of an increased risk of morbidities over time. There was no association between allostatic load and frequency of concussions and therefore a number of outcomes in the retired international rugby player group; with the exception of an unexpected inverse relationship between allostatic load and time to complete a fine motor co-ordination task. Conclusion: Findings from this thesis do not support the hypothesis that accumulated physiological dysregulation explain the heterogeneity after head injury. Some of the findings in this thesis require further study to investigate the pathophysiological consequences of higher neuroendocrine indicators at hospital discharge and metabolic indicators late after injury. Also it is important to understand the causes of increased metabolic and anthropometric component scores late after head injury to explore potential interventions to reduce possible increased risk of morbidities and mortality. The atypical findings in the investigation of allostatic load and repeat concussion indicate the accumulation of allostatic load in elite athletes is different to the general population. As none of the studies presented in this thesis found evidence for an association between allostatic load and disability outcome, there is a clear need for more research into factors that predict the heterogeneity of outcome after head injury.

Abstract:

INTRODUCTION: The question of when and if to perform follow- up CT scanning of the brain in a patient with a proven head injury remains pertinent, and the answer is not clear cut. This is even more so compounded when one tries to compare and equate what happens in a developed country with that of a developing country such as South Africa. AIM: To evaluate referral patterns, associated time-delays and findings of follow-up CT as well as patient outcomes in patients with head injury at Groote Schuur Hospital. METHOD: A retrospective review, over a 6 month time period, of the CT scans and folders belonging to patients who underwent follow-up CT scanning of the brain after blunt trauma to the head. RESULTS: There were 313 follow-up studies performed in 212 patients, of which the majority, 135 /313 (43.1%) were referred for neurological reasons, whilst 103/313 (32.9%) were referred for conservative management reasons and 75/313 (24%) were referred as part of their post-surgical check-up. There were significant time delays from arrival of patients in casualty to their initial CT scan (mean 18.74 hours) as well as between the initial CT and the first follow-up scan (mean 121.78 hours). There was a significant amount of data missing regarding the time of actual injury for many patients. There were 74 neurosurgical interventions that took place as a result of CT scans performed. Of these, 54 (73%) took place after the initial CT scan, whilst only 20 (27%) occurred after a follow-up CT. Of those surgical interventions performed after a follow- up study, 6 (30%) were performed as a result of a scan performed for post-surgical check- up. 12 (60%) were performed as a result of a scan performed for neurological reasons. Two (10%) neurosurgical interventions occurred as a result of a scan performed for conservative management reasons (thus routine follow-up imaging). CONCLUSIONS: A routine single follow-up CT may be a reasonable approach with further follow-up imaging reserved for patients who have undergone surgery, those with possibly surgically manageable findings on initial CT (that do not undergo surgery) and those with new neurology. The routine use of follow-up CT beyond the first follow-up CT is unlikely to lead to a change in management when the above clinical, and prior CT findings are absent. However, the time delays across all aspects of imaging traumatic brain injuries in our setting are unpredictable and represent a major problem in standardising when CT scans are performed.

Abstract:

Family and other social support is increasingly being recognised as a necessary component for comprehensive rehabilitation of the head injured. This study investigates the potentially constructive roles for relatives as co-therapists in ameliorating problems that persist after discharge from hospital and in-patient rehabilitation, if available. These are:- (a) As a source of information to help delineate the patient's problems. (b) As co-therapists, taking part in the planning and process of treatment. Four memory aids/mnemonics were devised and adapted from the literature on cognitive remediation aimed at reducing day-to-day memory problems. A multiple baseline design was used. The results suggest that relatives have a potential value in helping to achieve generalisation of memory techniques to real life environments. Single case studies highlight, the principles and practicalities of intervention, and the issues of family dynamics that arise during the course of treatment.

Abstract:

As a result of medical advancement and cultural patterns of Western society, traumatic head injury is increasingly a problem for the injured, their families, medical and social services professionals, and the community at large. Head trauma is remarkable because of the complex nature of the residual disabilities which include long lasting cognitive and emotional problems, social isolation, and family disruption. The purpose of this study was to re-examine the phenomenon of recovery after mild to moderate head injury using an ethnographic research approach. The data were based on the experiences of 21 disabled and their families in the community setting. The disabled represented a range of stages of recovery and severity of disability. The data was collected using three field work strategies: extensive semi-structured interviews, participant observation, and non-academic document review. After collection the data was subjected to thematic and content analysis, that resulted in the selection of themes that characterized the experiences for the head injured and their families. The themes for the head injured informants were: dead days, loneliness, and forgetting. The family members' experiences were represented in the themes: responsibility, vulnerability, tough love, gender differences, and reactions to the experience. Next the data were interpreted using five theoretical concepts from cultural anthropology: liminality, personhood, social labelling, sick role and double bind. In addition, the reflexive influence of the investigator on the research process was addressed. The trustworthiness of the ethnography was assessed in terms of credibility, transferability, dependability and confirmability. Several variables were found to be important to the long term outcome of head injury. These variables were: family directed therapy, double bind communication patterns, and lifelong recovery. Two other factors were found to be critical for the recovery of the head injured. These were economic disincentives to the return to employment and the importance of the social and family environment. In the final section the research and policy implications of the study were discussed in relation to management and service provisions.

Abstract:

Between 1.6 and 3.8 million sports-related concussions are sustained by persons living in the United States annually. While sports-related concussion was once considered to only result in immediate neurocognitive impairment and symptoms that are transient in nature, recent research has correlated long-term neurodegenerative effects with a history of sports-related concussion. Increased awareness and current media attention have contributed to concussions becoming a primary health concern. Although much research has been performed investigating the biomechanics of concussion, little is understood about the biomechanics that cause concussion in humans. The research presented in this dissertation investigates human tolerance to head acceleration using methods that pair biomechanical data collected from human volunteers with clinical data. Head impact exposure and injury risk are quantified and presented. In contrast to the publicly available data on the safety of automobiles, consumers have no analytical mechanism to evaluate the protective performance of football helmets. With this in mind, the Summation of Tests for the Analysis of Risk (STAR) evaluation system was developed to evaluate the impact performance of footballs helmets and provide consumers with information about helmet safety. The STAR evaluation system was designed using real world data that relate impact exposure to injury risk.

Abstract:

Following a mild head injury (MHI), a person may report a variety of symptoms such as headache, memory disturbance, dizziness, and concentration difficulties. For most persons the symptoms are transient, but some suffer persistent symptoms that can have a major impact on everyday life. It remains poorly understood why some but not others have full recovery after MHI. The aim of this thesis was to investigate outcomes after MHI, with particular focus on neuropsychological functioning, fatigue, and risk of dementia. A related objective was to examine the potential association of a genetic factor, Apolipoprotein (APOE), with MHI outcome. The APOE є4 allele has been associated with unfavorable outcomes after moderate or severe head injury, but little is known about its influence on outcome after MHI. In Study I and II, data from a population-based longitudinal study were used to compare neuropsychological functioning and fatigue before and after MHI. The results from Study I showed a post-injury decline in neuropsychological performance for є4-carriers, whereas the performance remained unchanged for non-carriers. Study II showed an increase in self-reported fatigue after MHI for both є4-carriers and non-carriers, with a more pronounced increase for є4-carriers. In Study III, a case-control study was conducted to examine whether a history of MHI increased the risk of developing dementia later in life. It was found that MHI alone did not increase the risk, but the combination of MHI and APOE є4 was associated with increased risk of dementia. Taken together, the studies generally indicate a positive outcome after MHI, but in combination with APOE є4 even mild head injury may lead to long-lasting negative outcomes. Consideration of pre-injury level of functioning and genetic factors seems critical for a complete understanding of the impact of MHI.

Abstract:

Background and aims: Head injury (HI) is a cause of cognitive impairment within the homeless population (Hwang et al, 2008). One study reported that over a 30-year period, the prevalence of hospitalised HI was 5.4 times higher in the homeless than in the general population (McMillan et al, 2015). This study explores the perceptions of homeless adults who have sustained a HI and their views regarding the relevance of HI to their homeless status. Methods: Participants were seven homeless adults with a moderate or severe HI. They were asked to talk about their journey to homelessness and in particular, to reflect on any perceived links between HI and their homeless status. The data were analysed using Interpretative Phenomenological Analysis (IPA). Results and conclusions: Emerging themes included: impairment following HI; substance misuse, feeling let down by services and difficult relationships with family. Evidence for the role of HI in precipitating and maintaining homelessness was found. Despite this, co-morbid difficulties complicate the picture. Four out of seven participants viewed substance misuse as their primary difficulty. This illustrates the need for in-depth assessment within this population in order to ensure that difficulties are fully understood and that the correct supports/ interventions are offered.

Abstract:

Introduction: Women in prison (WiP) in Scotland are six times more likely to have a hospitalised head injury (HI) than the general population and have higher relative risk of HI than men in prison. HI is linked to increased violent offending and poorer prison rehabilitation outcomes. This study aimed to explore the epidemiology of HI in WiP and identify any unmet needs. Methods: A retrospective cross-sectional design was utilised. 62 WiP were recruited from three Scottish prisons. Self-reported cause and severity of HIs, offending characteristics and comorbidities were recorded. Results: 88.7% of participants had a HI and 77.3% experienced periods of repeated blows to the head. Most likely cause of HI was assault. 68.4% of repeated HI episodes were caused by intimate partner violence (IPV). Number of HIs with LOC was significantly associated with number of arrests (rs=.398, p=.001; moderate effect size, 95% CI [.17, .61] and time in prison (rs=.299, p=.027; moderate effect size, 95% CI [.05, .54]). Participants with HI were significantly more likely to report violent offences than those with no HI, regardless of the HI severity (p=.043, odds ratio: 6.61, 95% CI [1.09, 40.3]). 86.5% of participants experienced HI before their first offence, indicating it may play a role in offending. Average age of first HI was 11 years, which links to poorer outcomes than adulthood HI. Conclusions: There were high rates of HI in WiP. HI was associated with offending characteristics and trauma. Further research is required with bigger sample sizes to confirm the role of HI in offending. Interventions for WiP may need to be adapted for HI populations and trauma-informed.

Abstract:

More than 19 million children participate in youth baseball and softball annually. Although baseball and softball are not commonly depicted as contact sports in the, according to the U.S. CPSC baseball and softball were responsible for 11.6% of all head injuries treated in emergency rooms in 2009; third most behind only cycling and football. Ball impact has been identified as the leading cause of injury in baseball and softball, with the most frequent injury resulting from a ball impacting the head. Reduced injury factor balls, infield softball masks, batter's helmets, and catcher's masks have all been integrated into baseball and softball as a means for preventing serious head injury from ball impact. The research in this thesis had four objectives: to compare the responses of the Hybrid III and NOCSAE headforms during high velocity projectile impacts, to compare head injury risk across a range of baseball stiffness designed for different age groups, to evaluate the effectiveness of infielder softball masks' ability to attenuate facial fracture risk, and to describe a novel methodology to evaluate the performance of batter's helmets and catcher's masks. Results of these research objectives determined the most suitable ATD headform to evaluate head injury risk for high velocity projectile impacts, provided a framework for determining the optimal age-specific ball stiffness and optimal infield mask design, and disseminated STAR ratings for batter's helmets and catcher's masks to the public. The research presented in this thesis can be used to further improve safety in baseball and softball.
