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 II, 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.
