Effect of Electromyographic Biofeedback Motion Sensing Game on Upper Limb Function in Children with Ob-stetric Brachial Plexus Injury / 中国康复理论与实践

ABSTRACT

Objective To investigate the effect of electromyographic biofeedback motion sensing game on upper limb function in chil-dren with obstetric brachial plexus palsy (OBPP). Methods From March, 2013 to February, 2014, 41 children with OBPP were randomly as-signed into conventional rehabilitation group (n=21) and motion sensing game group (n=20). Both groups underwent a comprehensive course of rehabilitation, and the motion sensing game group received upper limb occupational therapy in the motion sensing game, for four weeks. They were assessed with Mallet shoulder function scale and the surface electromyogram (EMG) of the deltoid muscle when abduct-ing the shoulder before and after treatment. Results Before treatment, there was no significant difference in the Mallet scores between two groups (t=0.730, P>0.05), the scores improved after treatment in both groups (t>5.085, P3.195, P4.420, P2.282, P2.155, P<0.05). Conclusion Electromyographic biofeedback motion sensing game therapy plays a role in the rehabilitation of upper limb function and muscle strength in children with OBPP.
