Role of a wireless surface electromyography in dystonic gait in functional movement disorders: A case report

Figure 1 Mean amplitude of a wireless surface electromyography activity and graphic display of analyzed electromyography signals during walking on the spot. A: Electromyography (EMG) amplitude of left medial and lateral gastrocnemius (GCM) muscles was larger than right medial and lateral GCM muscles. EMG amplitude was similar at the both tibialis anterior muscles; B: During 13 s, there were EMG bursts of double-contraction (thick arrow) in the left medial and lateral GCM muscles, while EMG analysis of right medial and lateral GCM muscles noted regular bursts of single contraction (thin arrow). EMG analysis of both tibialis anterior muscles were shown in similar bursts.

Figure 2 Mean amplitude of a wireless surface electromyography activity and graphic display of analyzed electromyography signals during forward walking. A: Electromyography (EMG) amplitude of left medial and lateral gastrocnemius (GCM) muscles was larger than right medial and lateral GCM muscles. EMG amplitude of left tibilis anterior (TA) muscle was slightly larger than the one of right TA muscle; B: When we analyzed EMG signals for each muscle during 20 s, there were EMG bursts of double-contraction (blue arrow) in the left medial and lateral GCM muscles, while EMG analysis of right medial and lateral GCM muscles noted regular bursts of single contraction (thin arrow). The bursts of left TA muscle were slightly higher and more than the ones of right TA muscle.
