Abstract:
Manual dexterity and stereognosis are supported by two exquisite sensory systems, namely touch and proprioception. Here, we measure the sensitivity of hand proprioception and show that humans can sense the posture and movements of the fingers with great accuracy. We also show that application of a skin vibration does not impair sensitivity, suggesting that proprioceptive acuity relies primarily on receptors in the muscles (and possibly tendons) rather than the skin.

Abstract:
In addition to being a prerequisite for many activities of daily living, the ability to maintain steady upright standing is a relevant model to study sensorimotor integrative function. Upright standing requires managing multimodal sensory inputs to produce finely tuned motor output that can be adjusted to accommodate changes in standing conditions and environment. The sensory information used for postural control mainly arises from the vestibular system of the inner ear, vision, and proprioception. Proprioception (sense of body position and movement) encompasses signals from mechanoreceptors (proprioceptors) located in muscles, tendons, and joint capsules. There is general agreement that proprioception signals from leg muscles provide the primary source of information for postural control. This is because of their exquisite sensitivity to detect body sway during unperturbed upright standing that mainly results from variations in leg muscle length induced by rotations around the ankle joint. However, aging is associated with alterations of muscle spindles and their neural pathways, which induce a decrease in the sensitivity, acuity, and integration of the proprioceptive signal. These alterations promote changes in postural control that reduce its efficiency and thereby may have deleterious consequences for the functional independence of an individual. This narrative review provides an overview of how aging alters the proprioceptive signal from the legs and presents compelling evidence that these changes modify the neural control of upright standing.

Abstract:
Aim. Objective evaluation of proprioceptive perception of single-joint movements of the paretic arm in patients with unilateral brain damage using the method developed by us. Materials and Methods. Proprioceptive perception of pronation-supination of the forearm, flexion-extension in the shoulder, elbow and wrist joints and abduction-adduction in the shoulder and wrist joints was tested in 23 patients with right-sided and 17 patients with left-sided brain damage. The subject with his eyes closed was made to perform a series of passive cyclical test movements, during which he had to copy them with active movements of the other arm. Joint angles were recorded in the test joint and the same joint ofthe other arm. The integrity of proprioceptive sensitivity was judged by the degree of similarity between “active” and “passive” movements estimated by means of objective qualitative and quantitative indicators. Results. Proprioceptive deficiency was detected in 83% of patients with lesion in the right and in 71% of patients with lesion inthe left hemisphere, while the proportion of test movements that revealed a violation of proprioceptive perception was 1.4 times higher in the right-hemisphere patients than in the left-hemisphere patients. A significant part of proprioceptive impairments, – 80% when testing movements of more distal and 29% – proximal segments of the arm, was detected by the presence of qualitative copying errors. Conclusions. The method used made it possible to identify proprioceptive deficits in more than half of patients with damage to both the right and left hemispheres. Proprioceptive perception of movements of the distal arm segment suffered more often and was more pronounced than the proximal one. A significant part of distal segment proprioception disorders manifested themselves in the form of gross qualitative copying errors, which can be detected visually during testing, even without the use of recording equipment.

Abstract:
Animals modulate sensory processing in concert with motor actions. Parallel copies of motor signals, called corollary discharge (CD), prepare the nervous system to process the mixture of externally and self-generated (reafferent) feedback that arises during locomotion. Commonly, CD in the peripheral nervous system cancels reafference to protect sensors and the central nervous system from being fatigued and overwhelmed by self-generated feedback. However, cancellation also limits the feedback that contributes to an animal’s awareness of its body position and motion within the environment, the sense of proprioception. We propose that, rather than cancellation, CD to the fish lateral line organ restructures reafference to maximize proprioceptive information content. Fishes’ undulatory body motions induce reafferent feedback that can encode the body’s instantaneous configuration with respect to fluid flows. We combined experimental and computational analyses of swimming biomechanics and hair cell physiology to develop a neuromechanical model of how fish can track peak body curvature, a key signature of axial undulatory locomotion. Without CD, this computation would be challenged by sensory adaptation, typified by decaying sensitivity and phase distortions with respect to an input stimulus. We find that CD interacts synergistically with sensor polarization to sharpen sensitivity along sensors’ preferred axes. The sharpening of sensitivity regulates spiking to a narrow interval coinciding with peak reafferent stimulation, which prevents adaptation and homogenizes the otherwise variable sensor output. Our integrative model reveals a vital role of CD for ensuring precise proprioceptive feedback during undulatory locomotion, which we term external proprioception.

Abstract:
Shoulder proprioception gives information regarding arm joint position and movement direction. Several studies have investigated shoulder proprioceptive acuity in patients with subacromial impingement syndrome (SIS); however, differences in protocols and between-subjects designs have limited scientific inferences regarding proprioception and SIS. We aimed to determine within-subject differences in shoulder and elbow proprioceptive acuity in 17 patients with stage 2 SIS following treatment of a local anesthetic injection. In addition, we used 17 healthy, age-, sex-, and arm dominance–matched controls to determine the magnitude of differences after treatment. Joint position sense (JPS) was measured before and after treatment in both groups in the sagittal plane for the shoulder and elbow. Our results indicate that patients with SIS have less sensitivity to angular position and tended to overshoot their targets with greater variability during angle-matching tasks for the shoulder (1.8° difference, P = .042) and elbow (5.6° difference, P = .001) than controls. The disparities in JPS found in patients with SIS were not resolved following subacromial injection; in fact, the magnitude of the errors increased after treatment where postinjection errors were significantly greater ( P = .046) than controls, with an average difference of 2.4°. These findings suggest that patients with SIS have decrements in either the signaling or processing of proprioceptive information and may use pain to reduce these inequalities.

Abstract:
The cuneate nucleus (CN) is the somatosensory gateway into the brain, and only recently has it been possible to record these signals from an awake animal. We recorded single CN neurons in monkeys. Proprioceptive CN neurons appear to receive input from very few muscles, and their sensitivity to movement changes reliably during reaching relative to passive arm perturbations. Sensitivity is generally increased, but not exclusively so, as though CN “spotlights” critical proprioceptive information during reaching.

Abstract:
It has been proposed that the brain predicts the sensory consequences of a movement and compares it to the actual sensory feedback. When the two differ, an error signal is formed, driving adaptation. How does an error in one trial alter performance in the subsequent trial? Here we show that the sensitivity to error is not constant but declines as a function of error magnitude. That is, one learns relatively less from large errors compared with small errors. We performed an experiment in which humans made reaching movements and randomly experienced an error in both their visual and proprioceptive feedback. Proprioceptive errors were created with force fields, and visual errors were formed by perturbing the cursor trajectory to create a visual error that was smaller, the same size, or larger than the proprioceptive error. We measured single-trial adaptation and calculated sensitivity to error, i.e., the ratio of the trial-to-trial change in motor commands to error size. We found that for both sensory modalities sensitivity decreased with increasing error size. A reanalysis of a number of previously published psychophysical results also exhibited this feature. Finally, we asked how the brain might encode sensitivity to error. We reanalyzed previously published probabilities of cerebellar complex spikes (CSs) and found that this probability declined with increasing error size. From this we posit that a CS may be representative of the sensitivity to error, and not error itself, a hypothesis that may explain conflicting reports about CSs and their relationship to error.

Abstract:
abstract: Proprioception is the sense of body position, movement, force, and effort. Loss of proprioception can affect planning and control of limb and body movements, negatively impacting activities of daily living and quality of life. Assessments employing planar robots have shown that proprioceptive sensitivity is directionally dependent within the horizontal plane however, few studies have looked at proprioceptive sensitivity in 3d space. In addition, the extent to which proprioceptive sensitivity is modifiable by factors such as exogenous neuromodulation is unclear. To investigate proprioceptive sensitivity in 3d we developed a novel experimental paradigm employing a 7-DoF robot arm, which enables reliable testing of arm proprioception along arbitrary paths in 3d space, including vertical motion which has previously been neglected. A participant’s right arm was coupled to a trough held by the robot that stabilized the wrist and forearm, allowing for changes in configuration only at the elbow and shoulder. Sensitivity to imposed displacements of the endpoint of the arm were evaluated using a “same/different” task, where participant’s hands were moved 1-4 cm from a previously visited reference position. A measure of sensitivity (d’) was compared across 6 movement directions and between 2 postures. For all directions, sensitivity increased monotonically as the distance from the reference location increased. Sensitivity was also shown to be anisotropic (directionally dependent) which has implications for our understanding of the planning and control of reaching movements in 3d space. The effect of neuromodulation on proprioceptive sensitivity was assessed using transcutaneous electrical nerve stimulation (TENS), which has been shown to have beneficial effects on human cognitive and sensorimotor performance in other contexts. In this pilot study the effects of two frequencies (30hz and 300hz) and three electrode configurations were examined. No effect of electrode configuration was found, however sensitivity with 30hz stimulation was significantly lower than with 300hz stimulation (which was similar to sensitivity without stimulation). Although TENS was shown to modulate proprioceptive sensitivity, additional experiments are required to determine if TENS can produce enhancement rather than depression of sensitivity which would have positive implications for rehabilitation of proprioceptive deficits arising from stroke and other disorders.

Abstract:
Les chutes chez les personnes âgées ont été attribuées à une baisse de la fonction proprioceptive ainsi qu'à une incapacité à allouer suffisamment d’attention au maintien de l'équilibre dans des conditions multitâches. Cette étude vise à explorer l'interaction entre les demandes proprioceptive et attentionnelle du contrôle postural dynamique de la personne âgée. Des adultes sédentaires âgés et jeunes ont effectué une tâche de limite de la stabilité posturale avec et sans vision ainsi qu’une tâche attentionnelle secondaire de soustraction mathématique (n-3). Ces deux tâches étaient effectuées soit seul (tâche simple) ou simultanément (tâche double). La force de réaction au sol a été collectée à 200 Hz en utilisant une plateforme de force AMTI et les déplacements des centres de pression (COP) ont été analysés. Les limites fonctionnelles de la stabilité ont été quantifiées comme l'excursion maximale du COP pendant l'inclinaison volontaire du corps dans chaque direction. Nous avions émis l'hypothèse que les plus grandes différences liées à l'âge seraient observées dans la condition de tâche double en raison des limitations des ressources attentionnelles pour faire face simultanément à des exigences proprioceptives et cognitives élevées. Nos résultats indiquent que l’addition de la tâche attentionnelle n’a pas influencé les limites de stabilité posturales des participants. Cependant, les personnes âgées ont significativement diminué leur performance dans la tâche attentionnelle lorsqu’ils ont effectué simultanément la tâche posturale, particulièrement en l’absence de vision. Ces résultats supportent l’idée d’une interaction entre les demandes proprioceptives et attentionnelles du contrôle postural dynamique chez la personne âgée.
Falls among seniors have been attributed to declines in proprioceptive function as well as an inability to efficiently allocate attention to balance in multi-task conditions. This study aims to explore the interaction between the proprioceptive and attentional demands for dynamic postural control in seniors. Old and young sedentary adults performed a postural stability limit task with and without vision as well as a secondary attentional subtraction task (n-3). These two tasks were performed either alone (single task) or simultaneously (dual-task). Ground reaction force was collected at 200 Hz using an AMTI force platform and centre of pressure (COP) was analyzed. The functional limits of stability were quantified as the maximum COP excursion during voluntary leaning in each direction. We hypothesized that the greatest age-related differences would be seen under the dual-task condition because of limitations in attentional resources available for concurrently coping with high proprioceptive and cognitive demands. Our findings indicated that the stability limits of both subject groups were not influenced by the addition of the cognitive attentional task. However, seniors markedly decreased their performance in the cognitive task while simultaneously performing the postural task and this trend was accentuated in the absence of vision. These results support the idea of an interaction between the proprioceptive and attentional demands of dynamic postural control in seniors.
