BACKGROUND AND PURPOSE The Hoffmann reflex (H-reflex) is widely acknowledged as an indirect indicator of spinal motor neuron excitability. The purpose of this study was to determine whether transcutaneous electrical stimulation (TES), applied over the dorsiflexors or plantar flexors of the ankle, would alter the soleus muscle's H-reflex. Attention was focused on the roles of stimulus intensity ...

Human postural control requires continuous modulation of ankle torque to stabilize the upright stance. The is generated by two components: active contributions, due central and stretch reflex, passive mechanisms, joint intrinsic stiffness. Identifying contribution each component difficult, since their effects appear together, standing controlled in closed-loop. This article presents a novel mul...

A better understanding of autonomic influence on motor reflex pathways in spinal cord injury is important to the clinical management of autonomic dysreflexia and spasticity in spinal cord injured patients. The purpose of this study was to examine the modulation of flexor reflex windup during episodes of induced sympathetic activity in chronic human spinal cord injury (SCI). We simultaneously me...

This study aims to quantify how habitual foot strike patterns would affect ankle kinetics and the behavior mechanics of medial gastrocnemius–tendon unit (MTU) during running. A total 14 runners with non-rearfoot (NRFS) 15 rearfoot (RFS) ran on an instrumented treadmill at a speed 9 km/h. An ultrasound system motion capture were synchronously triggered collect images gastrocnemius (MG) marker po...

35 years old male patient presented clinically with progressive lower limb weakness and impotence of 3 years duration, disturbance of micturation with few drops of urine passing without the patient control was a prominent symptom. On examination the patient had atrophy of the anterior tibial group of muscles on the right side, with bilateral spasticity in both lower limbs and a sensory level at...

INTRODUCTION Polyneuropathy is one of the most prevalent neurologic disorders. Although several studies explored the role of the neurological examination in polyneuropathy, they were mostly restricted to specific subgroups of patients and have not correlated examination findings with symptoms and electrophysiological results. OBJECTIVES To explore the sensitivity and specificity of different ...

STUDY DESIGN Cross-sectional study with prospective recruitment. OBJECTIVE.: To determine the accuracy of the physical examination for the diagnosis of midlumbar nerve root impingement (L2, L3, or L4), low lumbar nerve root impingement (L5 or S1) and level-specific lumbar nerve root impingement on magnetic resonance imaging, using individual tests and combinations of tests. SUMMARY OF BACKGRO...

CONTEXT Several researchers have suggested that improving evertor strength and peroneus longus reaction time may help alleviate the symptoms of chronic ankle instability and reduce the rate of recurrent ankle sprains. OBJECTIVES To determine the effectiveness of a 4-wk elastic-resistance exercise-training program on ankleevertor strength and peroneus longus latency in subjects with and withou...

INTRODUCTION Individuals suffering from cerebral palsy (CP) often have involuntary, reflex-evoked muscle activity resulting in spastic hyperreflexia. Whole-body vibration (WBV) has been demonstrated to reduce reflex activity in healthy subjects, but evidence in CP patients is still limited. Therefore, this study aimed to establish the acute neuromuscular and kinematic effects of WBV in subjects...
