Abstract |
PURPOSE The purpose of this study was to provide an optimal condition for gait practice in water based on the kinematic analysis of gait pattern with different water levels. METHOD The water levels of 0.7m 1.2m, and 1.3m were used for this study based on the heights of knee, chest, and neck. Kinematic variables during gait including gait duration time, step length, and maximum and minimum heights of the knee joint were analyzed for both affected and non-affected sides. The orientation angles and angular velocities of the ankle and knee joints were also analyzed based on the different water levels.
CONCLUSION For the gait duration time (sec), the 0.7m exhibited the significant increase in the gait duration time as compared to the 1.3m in both sides (p<.05). For the step length (cm), both sides indicated the significant increase in the step length as the water level gets deeper (p<.05). For the orientation angle (degree), the change in the orientation angle of the hip joint was greater for the 1.3m (7.734±2.167) than the 1.2m (6.152±2.569) in the affected side (p<.05). In conclusion, the increase in the support time and the step length resulting from the increase in the orientation angle of the hip joint were observed as the water level gets deeper in both sides. Therefore, it is considered that gait exercise in water can be effective at the chest level of water in order for patients to experience more buoyancy. |
