Abstract

Objective: The modulation of short latency reflex linking the pretibial to quadriceps muscle (CPQ reflex) was investigated in seven subjects during walking on a treadmill at the stance to swing transition period.

Methodology: The intensity of quadriceps (Q) EMG was increased throughout the gait cycle by using a modified knee orthosis. Pairs of spring were added to the orthosis to produce different levels of muscular activity in Q during the midstance, transition period and terminal swing phase of gait. Electrical stimulation was applied to the common peroneal nerve (CPN) at these three instants of gait.

Results: The peak to peak amplitude of CPQ reflex was significantly increased with escalation of background EMG in Q during midstance (p<0.015) and terminal swing (p<0.04). At the
