Purpose : The purpose of this study was to investigate muscle activity of affected lower extremity by unaffected lower extremity exercise and tried to examine muscle activity of affected lower extremity of hemiplegic patients were caused by stroke according to wearing single strap hemisling or non-wearing. Methods : We measured muscle activity of affected lower extremity when wearing single strap hemisling to affected lower extremity or non-wearing according to unaffected lower extremity used MP 150 Eletromyogram. Results : 1) Muscle activity of gluteus medius muscle was the highest D1 before wearing single strap hemisling. 2) Muscle activity of hamstring muscle was the highest D3 after wearing single strap hemisling. 3) Muscle activity of quadriceps muscle was the highest D5 after wearing single strap hemisling. 4) Muscle activity of tibialis anterior muscle was the highest D1 after wearing single strap hemisling. 5) Muscle activity of soleus muscle was the highest D2 before wearing single strap hemisling. Conclusion : Wearing single strap hemisling of hemiplegic patients had effect on muscle activity of gluteus medius but didn't effect gluteus medius, hamstring, quadriceps, tibialis anterior muscle and soleus muscle.

Purpose: This study was to investigate the effect of an arm sling on gait with hemiparesis. Methods: Fifteen patients(8 male, 7 female) with hemiparesis participated in this study and walked self-selected speed over 10m walkway, randomly without arm sling, with Single strap hemisling and Rolyan humeral cuff sling. It were filmed by 5 video camera and used with 3-dimensional motion analyzer system. The following gait variables were analyzed: temporo-spatial parameters, kinematic parameters. Results: In the comparison of temporo-spatial parameters each trial, walking velocity and single support time on affected side was significantly increased and step length on affected side, step length asymmetry ratio, single support time asymmetry ratio was significantly decreased in the Single strap hemisling and Rolyan humeral cuff sling. In the comparison of kinematic parameters each trial, maximal angle of the hip flexion on affected side was significantly increased in the Single strap hemisling and Rolyan humeral cuff sling and maximal angle of the knee flexion on affected side was significantly increased in the Rolyan humeral cuff sling and maximal angle of the ankle dorsiflexion on affected side was significantly increased in the Single strap hemisling. Conclusion: An arm sling improved walking velocity and decreased asymmetry and increased maximal angle of hip, knee, ankle flexion on affected side with hemiparesis caused by stroke.
