Changes in sEMG activity of both sides of sternocleidomastoid under different inspiratory pressure loads. RMS Root mean square, sEMG Surface electromyography, MIP Maximum inspiratory pressure; Inserted numbers are mean sEMG ± SD. Data of the hemiplegic side are in italics. Comparison between hemiplegic and non-affected sides at different inspiratory pressure loads denoted by *p < 0.05 or **denotes p < 0.001.
