Spinal reflexes are often viewed as stereotyped motor patterns with limited scope for
modification. This presumed invariance is contrasted to the greater adaptive possibilities found in …

Walking the way we do is inherently unstable. Sophisticated neurological control systems
are required to ensure that we progress and maintain our balance at the same time. Most of …

In this paper, the following experimental methods for studies of the motor system in freely
moving human subjects will be considered: (i) eliciting the H-reflex and understanding its use …

Experiments were done to determine the amplitude of the monosynaptically mediated H-reflex
of the soleus muscle at various phases of the step cycle, using a computer-based analysis …

Experiments were done to determine the form of the input-output relation (ie stimulus intensity
vs response amplitude) of the corticospinal pathway of the first dorsal interosseous and …

1. The Hoffman reflex, or H reflex, was strongly modulated in the human soleus muscle during
both walking (4 km/h) and running (8 km/h). It was relatively low at the time of heel contact, …

Muscle tendon vibration was applied during voluntary step-tracking arm target-movements
performed by normal human subjects. Vibration (freq. = 120 Hz) was applied over either the …
