Responsiveness of the H reflex to loading and posture in patients following stroke
TLDR
Current electrophysiological findings imply that body weight as a means for rehabilitation facilitation had little immediate effect on paretic TS, and absence in postural gating of reflex excitability appeared to be an incentive for postural instability resulting from post-stroke hemiparesis.About:

Physical Exercise as a Diagnostic, Rehabilitation, and Preventive Tool: Influence on Neuroplasticity and Motor Recovery after Stroke
Caroline Pin-Barre,Jérôme Laurin +1 more
TL;DR: Regular physical activity may also decrease the motor outcome severity of stroke, and physical exercise might also be considered as a major nonpharmacological preventive strategy that provides neuroprotective effects reducing adverse effects of brain ischemia.

What triggers the continuous muscle activity during upright standing
TL;DR: The results suggest that the vertical load on the lower limb is not determinant for inducing the continuous muscle activity in the anti-gravity muscles, but that it depends on the required joint torque to oppose the gravity toppling torque.
Journal ArticleDOI
Test–retest reliability of the soleus H-reflex is affected by joint positions and muscle force levels
TL;DR: The test-retest reliability of the soleus (SOL) H-reflex was affected by the intensity of voluntary contraction and ankle joint position, and demonstrated a higher reliability at the neutral and plantarflexion positions than that at the dorsiflexion position during rest.
Journal ArticleDOI
Characterization of the mechanical and neural components of spastic hypertonia with modified H reflex
TL;DR: It was concluded that spastic hypertonia involved an atypical increase in motoneuronal excitability and muscle mechanical properties, while impairment of functional performance and daily activity was attributable primarily to altered mechanical properties of a spastic muscle.
Journal ArticleDOI
Modulation of soleus H reflex due to stance pattern and haptic stabilization of posture
TL;DR: Gating of the soleus H reflex indicated adaptation of an ankle strategy to stance pattern and haptic stabilization of posture in unilateral stance, and alteration in postural sway and modulation of the joint were not mutually correlated when stance pattern or touch vector varied.

Journal ArticleDOI
The significance of proprioception on postural stabilization as assessed by ischemia.
TL;DR: Results indicate that proprioceptive input from skin, pressure and joint receptors of the foot (ischemia at the ankle) is of minor importance for the compensation of rapid displacements, but plays a significant role when the platform moves at low frequencies.

Proprioceptive Neuromuscular Facilitation: Patterns and Techniques
Margaret Knott,Dorothy E. Voss +1 more
TL;DR: In this article, the authors present both the "what" and the "how to" in education and therapy in neuromuscular re-education. And they present a practical approach to therapeutic exercise and neurOMuscular education.

Significance of load receptor input during locomotion: a review
Volker Dietz,Jacques Duysens +1 more
TL;DR: It can be concluded that during locomotion there is a closing of Ib inhibitory and an opening of Ib extensor facilitatory paths, which represents a newly discovered function of these receptors in the regulation of stance and gait in cat and humans.

CHANGES IN PRESYNAPTIC INHIBITION OF Ia FIBRES IN MAN WHILE STANDING
TL;DR: It is argued that the substantial changes in monosynaptic Ia excitation observed when standing without support probably reflect changes in presynaptic inhibition of Ia fibres, and it is assumed that changes in the size of the peak of facilitation elicited by the monosynthetic postsynaptic potential (EPSP) are likely to be caused by changes in Presynaptic inhibited fibres.

A quantitative assessment of presynaptic inhibition of Ia afferents in spastics. Differences in hemiplegics and paraplegics.
TL;DR: Soleus H-reflex facilitation evoked by a supramaximal conditioning stimulation to the femoral nerve was investigated in 28 healthy control subjects and 35 spastic patients, indicating that presynaptic inhibition of Ia terminals is unchanged in these patients and disagrees with the usual interpretation of reduced vibratory inhibition of the soleus H -reflex in hemiplegics.
