Effects of gait training on sand on improving the walking ability of patients with chronic stroke:a randomized controlled trial

[Purpose] This study examines how difference in sandy ground between firm ground influences the effects of gait training in patients with chronic stroke. [Subjects and Methods] A total of 28 patients with chronic stroke were evenly divided into experimental and control groups. Initial evaluation of the subjects was conducted by Timed Up & Go (TUG) and 6-Minute Walking Test (6MWT). Each patient in both groups received daily, 30-minute gait training on sandy ground and firm ground, five times each week, for a total of six weeks, after which reevaluation was conducted. [Results] In TUG, both groups showed significant improvement after the intervention. In 6MWT, only the experimental group achieved significantly increased distance after the intervention. However, there was no between-group difference. Improvement in dynamic balancing ability depends on repeated gait training rather than differences in the ground environment. However, gait endurance showed a difference depending on the types of ground, regardless of repeated gait training. [Conclusion] This can be attributed to the fact that gait training on sand requires use of more diverse muscles. Hence, we can confirm the potential of sand as a new material for training ground when attempting to improve walking ability, particularly gait endurance, among patients with chronic stroke.
