Abstract
Increases in low threshold EMG may occur as a consequence of mobility or daily activity. The purpose of this study was to determine whether mobility (ambulation and life-space movement) or activities of daily living influence low-threshold EMG in older women (>75 years). EMG was examined in upper and lower body muscles for an 8-hour day and compared with assessments of mobility from Global Positioning Systems and pedometers. Although mobility scores did not differ between groups, community-dwelling women reported higher instrumental activities of daily living compared with retirement-dwelling. EMG burst activity was ~25% greater and gap activity ~45% less in retirement-dwellers. Upper extremity muscles had ~45% greater number and rate of bursts and gaps than lower extremity muscles. On and off cycle of low threshold EMG in upper extremities and higher burst and lower gap activity in retirement-dwelling women likely occurs because EMG is sensitive to instrumental activities of daily living.
