Abstract:
Objective To study balance function and surface electromyography (sEMG) activity of erector spinae (ES) and rectus ab-dominis(RA)in stroke patients.Methods From April,2015 to December,2016,17 stroke patients(test group)and 13 healthy subjects(con-trol group)were tested with balance platform:sitting with eyes open/close,with the platform swing of 10°,with trunk flexion and extension in maximum.The root mean square(RMS)of sEMG was recorded on both sides of ES and RA synchronously.The swing length and area of center of mass,the center of pressure on X and Y axes were also recorded as sitting with eyes open/close.Results For the test group,RMS of bilateral ES was significantly different as sitting with eyes open/close and with trunk flexion and extension in maximum (t>2.173, P<0.05).Compared with the control group,RMS of ES and RA in unaffected side increased as sitting with eyes open/close(t>2.175,P<0.05), as well as the swing length and area of center of mass(t>2.760,P<0.05).Conclusion The strength imbalance is found in ES in stroke pa-tients,which may associate with the balance function impairment,and need to be improved in rehabilitation.
