EMG plots from two exemplar subjects. a-b EMG responses in the spastic and contralateral BB-lateral muscle of one stroke subject. c EMG response from the BB-lateral of the dominant arm of one control subject. d-e EMG responses in the spastic and contralateral BB-medial muscle of the same stroke subject. f EMG response from the BB-medial of the dominant arm of the same control subject. The reflex threshold for the spastic side was 4 mm as measured from the BB-lateral (a) and 5 mm as measured from the BB-medial muscle (d). The reflex threshold for the contralateral side was 13 mm (b and e). No reflex response was detected for the control subject despite tapping the tendon at an indentation of 24 mm (c and f). Note the different scales.
