Effect of blocked vision treadmill training on knee joint proprioception of patients with chronic stroke

Abstract

[Purpose] The purpose of this study was to compare the effect of treadmill training with the eyes closed and eyes open on the joint position sense of chronic stroke patients. [Subjects and Methods] Thirty patients with chronic stroke participated in this study. Patients performed the timed up and go test and were assigned to one of two treadmill training groups with and without visual deprivation. The treadmill gait training for each group lasted 40 minutes, and sessions were held 3 times a week for 4 weeks. The knee joint proprioception was measured using the Biodex System Pro 3 before and after the intervention. [Results] The knee joint proprioception of the treadmill training with blocked vision group showed more significant improvement after the treadmill training sessions than that of the eyes open group. [Conclusion] This study demonstrated that treadmill training with blocked vision may be useful for the proprioceptive sensory rehabilitation of patients with chronic stroke.
