Abstract
Objective: The aim of this study was to investigate the effectiveness of the ToeOFF AFO in hemiplegic gait in CVA patients with ankle paralysis problem, and compared it with the conventional custom-made solid ankle AFO. The comparison would include biomechanical performance in spatio-temporal parameters, joint kinematics, and joint kinetic as well as the ankle-foot roll-over shape, asymmetry ratio, and push-off power in terminal stance.esign: Experimental gait analysis; Repeated measure ANOVA analysis.articipants: Nine CVA hemiplegia patients (5 males, 4 females) participated in this study. Five subjects were left and four were right involved.etting: Rehabilitation Engineering Research Center with instrumented gait laboratory. nterventions: Three conditions: shoes only (SHOE), shoes with solid ankle AFO (SAFO), and the same shoes with ToeOFF AFO (TOEOFF).ain outcome measures: Significance in spatio-temporal parameters, gait performance, asymmetry ratio, and ankle-foot roll-over shape. esults: The major finding of this study included: (1) the ToeOFF AFO was found to be consistent of the hypotheses, which improved the walking speed, cadence step length, temporal symmetry, ankle power generation, foot contact patterns, and energy cost; (2) in subjects of drop foot group, the power flow analysis showed that part of the greater power generation with the ToeOFF AFO was partially transferred to trunk as support; (3) the SAFO provided more stability resulted in improving the spatio-temporal parameters more. onclusion: For CVA patients, walk with an adequate AFO to compensate the deficit functions is a very important issue in rehabilitation work. Dissimilar configurations of AFOs provide different effectiveness for certain condition of patients. The results of this study supported that the SAFO provided better stability, and the ToeOFF AFO provided better power generation. The generated power could make use for propulsion in more stable patients. Accordingly, these findings in the present study provided as a reference to choose an adequate AFO by considering what’s the majority of the patients need? The propulsion power or the stability is.ey words: Stroke, Gait analysis, Ankle-foot orthosis, Energy consumption
