Texto completoEccentric contractions induce distinct neural control compared to isometric and concentric contractions. Although some postsynaptic mechanisms, such as recurrent inhibition, have been identified as playing a role in this specific control, the involvement of presynaptic mechanisms remains to be demonstrated. As mechanical constraints increase particularly in the final phase of eccentric contractions, variations in muscle length may lead to different afferent feedback (Ia and II) to the spinal cord, thereby affecting motoneuron activity. The aim of this thesis was to explore (i) the characteristics of the nervous system during eccentric contractions, (ii) to assess the influence of muscle length on neural control during passive and active (eccentric contractions) muscle elongations, and (iii) to determine whether muscle length can modulate the long-term adaptive responses observed following eccentric training. Four studies contributed to this thesis. These studies measured mechanical parameters, such as torque and muscle fascicle length, as well as neural parameters, including corticospinal excitability, the efficiency of synaptic transmission between Ia afferent fibres and α- motoneurons, reflex gain, underlying regulatory mechanisms, and electromyographic activity of the muscles. The results indicate that presynaptic mechanisms play a crucial role in the neural control of eccentric contractions. Variations in muscle length, particularly during phases at long length, distinctly influence the activity of spinal inhibitory mechanisms during both passive and active elongations. Finally, muscle length may promote long-term neural plasticity by more effectively optimising the underlying mechanisms for submaximal contractions. However, for maximal contractions, the nervous system appears to limit adaptations, potentially reflecting a protective mechanism

Texto completoEccentric contractions induce structural disruptions of exercised muscle fibers, which refer to as muscle damage phenomenon. Although described for in vitro model, underpinning mechanisms of muscle damage remain unclear for in vivo model. This thesis aimed at investigate (i) mechanical and neural behaviors of the neuromuscular system during maximal eccentric contractions in Human and (ii) the effect of these mechanical and neural behaviors on the magnitude of muscle damage. This thesis was divided into six studies, in which mechanical parameters, such as the level of generated joint force and the length of muscle fascicles; and neural parameters, such as the ability to fully activate a muscle voluntarily and corticospinal excitability, during maximal eccentric contractions were measured. These mechanical and neural parameters were also related to muscle damage functional symptoms (i.e., force loss and muscle soreness). The findings showed that muscle damage is related to a compound influence of mechanical and neural factors involved during eccentric contractions. However, neural inhibitory processes at long muscle lengths, and the contribution of tendinous tissues in total muscle-tendon unit lengthening during maximal eccentric contractions allow to reduce the magnitude of muscle damage

Texto completoDirect electrical stimulation (DES) for one hour increases the rate of peripheral nerve regeneration in rats after nerve repair. Clinically, this would lengthen surgery time, increasing risks of perioperative complications. Purpose: This study examines whether transcutaneous electrical stimulation (TCES) is as effective at improving peripheral nerve regeneration as direct electrical stimulation. Methods: The right sciatic nerve was axotomized in 28 mice. End-to-end microsuture repair was undertaken. Four groups were studied: (1) sham; (2) suture only; (3) suture and DES; (4) suture and TCES. Stimulation was applied for 1 hour, at 20 Hz. The mice were studied for a total of 12 weeks. Hind-limb recovery was evaluated at weeks 0, 1, 2 and then every 2 weeks by walking-track analysis. Results: Post recovery kinematic showed significantly improved functional sciatic index and foot-base angles at weeks 8, 10 and 12 for both DES and TCES groups. Conclusions: 12 weeks after sciatic nerve axotomy, functional recovery was improved significantly in both DES and TCES groups. Therefore, TCES is as beneficial in promoting nerve regeneration and functional muscle reinnervation as is DES.

Texto completoPurpose: Hepatocyte Growth Factor (HGF) plays a role in promoting axonal growth and survival of motoneurons during embryonic development. This factor might also be important in directing the regeneration of adult motoneurons following laceration. We aim to identify the expression patterns of HGF following axotomy, with or without direct or transcutaneous electrical nerve stimulation in a mouse model. Methods: Sixty adult C57BL/6 mice were divided into 5 groups: Control (n=12), Sham (n=12), Axotomy (n=12, sciatic nerve laceration and immediate repair), Direct (n=12, sciatic nerve laceration, immediate repair and application of direct electrical stimulation on the proximal nerve end, 1h, 20 Hz) and Transcutaneous (n=12, nerve laceration and immediate repair followed by proximal transcutaneous electrical stimulation, 1h, 20 Hz). Spinal cords were harvested at 1, 3, 7 and 14 days post-surgery. The expression patterns of HGF were measured using in situ hybridization. Results: Our results showed an upregulation of HGF expression in mouse spinal cords following sciatic nerve axotomy. This occurred more quickly following electrical stimulation in both Direct and Transcutaneous groups. The expression pattern of HGF became localized to the motor neuron pools in the Axotomy, Direct and Transcutaneous groups. Conclusions: HGF, a growth factor involved in directing the outgrowth of motor axons in development, has an altered expression pattern following sciatic nerve laceration, suggesting it may also play a role in directing motoneuron regeneration. Furthermore, rapid change in the expression pattern of HGF following electrical stimulation suggests it may also be involved in the upregulation of nerve regeneration following electrical stimulation.
