FOOT IMPAIRMENTS AND LIMITATIONS IN WALKING ACTIVITIES IN PEOPLE AFFECTED BY LEPROSY

Objective: To explore the relationships between perceived limitations in walking-related daily activities, walking ability (capacity), and the amount of daily walking (performance) in persons affected by leprosy and to identify their determinants. Design: A cross-sectional study. Subjects: Thirty-nine persons affected by leprosy. Methods: Perceived limitations were assessed with the World Health Organization Disability Schedule 11, domain "getting around". Walking capacity was assessed as covered distance in 6 min. Walking performance was recorded as mean strides/day with the Stepwatch(TM) 3 Activity Monitor. Potential determinants were sensory function, foot deformities, joint mobility, ankle muscle strength and co-morbidity. Results: Perceived limitations in walking-related activities were significantly correlated with walking capacity (r=-0.47; p <0.01) but not with walking performance, although walking capacity significantly correlated with walking performance (r=0.38; p <0.05). Various foot impairments independently contributed to reduced walking capacity and, to a lower degree, to perceived limitations in activities and performance. Conclusion: People affected by leprosy perceive limitations in walking-related activities that are determined by a reduced walking ability and the severity of foot impairments. Since perceived limitations in walking-related activities were not related to walking performance, perceived limitations are apparently weighted against the individual's needs
