Occupational Potential in a Population with Duchenne Muscular Dystrophy

Twenty-five males, ranging in age from 7 to 23 years, who had Duchenne muscular dystrophy were tested using both standardized and functional tests to assess their potential for occupational activity despite diminishing neuromuscle status. The purpose was to determine possible sensory deficits (specifically visual-spatial organization), strength, endurance, and fatigue in response to sustained upper-extremity fine motor activity over a period of three to four hours. Statistical analysis of the results indicated normal visual-spatial organization skills, no performance decrements, and improved performance on some tests. A series of grip-strength measures did not indicate a statistically significant decreasing linear trend. The conclusion is that, within limitations, persons with this diagnosis can engage in activity leading to skill development and productivity.
