The effects of 12-week exercise therapy program on the gait characteristics in people with Parkinson’s disease

초록

Objective: The purpose of this study was to investigate the effects of 12-week exercise intervention (12-ET) on balance and gait characteristics (temporal-spatial parameters, joint angles, and muscle activities) in Parkinson’s disease (PD) patients. Methods: Eleven people with PD (H and Y stage 3; 63.5 years) participated in the study. They performed balance (timed up and go) test and walked 3 times in the GAITRite system at a self-selected speed. The participants undergone exercise programs (stretching, Codi-X, ladder-X, gym ball & band) two times per week, 60 min each time. The temporal-spatial variables were calculated by GAITRite system. The electromyographic (EMG) signals from tibialis anterior, medial gastrocnemius (MG), lateral gastrocnemius, soleus, rectus femoris, vastus lateralis (VL), semitendinosus, biceps femoris were recorded during reference voluntary contractions (RVC) using EMG system (Noraxon, Inc.). Maximum hip, knee, and ankle joint angles in the gait cycle were calculated using 3D wireless inertial motion measurement system (Myomotion, Inc.). Statistical analysis were done using paired t-test with Bonferroni adjustments. Results: Theres were significant decreases in timed up and go test (15.64 vs 11.92 s). The ambulation time (6.94 vs 2.96 s), double support time (0.42 vs 0.27 s), stance of cycle (71.4 vs 63.0%cycle), and double support cycle (43.8 vs 27.0%cycle), while significant increases in swing time (0.27 vs 0.36 s), single support time (0.25 vs 0.35 s), swing of cycle (28.6 vs 37.0%cycle), single upport cycle (26.9 vs 36.1%cycle), heel off on time (0.02 vs 0.12 s), gait velocity (0.61 vs 1.05 m/s), normalized velocity (0.74 vs 1.29 m/s), stride velocity (0.62 vs 1.05 m/s), step length (0.37 vs 0.51 m), step extremity ratio (39.8 vs 62.6%), stride length (0.56 vs 1.02 m), and functional ambulation profile (FAP) score (63.8 vs 87.3 point) after 12-ET.MG (157.6 VS 124.8%RVC) significant decreases during the mid-stance, while VL
