Abstract

OBJECTIVE: The aim of this meta-analysis was to investigate the effects of ankle foot orthosis on adult post-stroke hemiplegic patients' walking ability and pattern. METHOD: We searched for the case controlled clinical trials about the effects of ankle foot orthosis (AFO) for walking ability and pattern using quantitative gait analysis in adult post-stroke patients, which published between January 1950 and July 2012 in PubMed, and searching engine of Journal of Korean Academy of Rehabilitation Medicine. The mean standardized difference (MSD) and a 95% confidence interval (CI) were estimated for gait ability and pattern using fixed effect models.
RESULTS
Sixteen of the 56 articles were included in this analysis. The selected studies involved a total of 274 patients. The walking speed, cadence, the portion of double limb supporting, stride length on affected side, the portion of swing period on unaffected side, and symmetry of swing period were improved by AFO. The oxygen cost was decreased by AFO. The AFO did improve ankle dorsiflexion at initial contact, maximal ankle dorsiflexion at swing phase, but the ankle plantar flexion at push-off did not.
CONCLUSION
The ankle foot orthosis has some evidence to improve the walking ability and gait pattern in post-stroke hemiplegic patients.
