Brief Summary

Stroke patients have higher levels of visual dependence, which affects orientation, balance and gait. Visual adaption or habituation training aiming to decrease visual sensitivity and tolerance, is commonly used to decrease the levels of visual dependence. However, the visual adaption training often evokes unbearable vertigo, resulting in lower compliance to training program. In addition, stroke patients who have higher visual dependence may not have the symptom of dizziness. Therefore, it is unclear whether visual adaption training has similar effects on stroke patients. Visual dependence is considered as a sensory reweighting deficit and therefore visual dependence could be improved through multisensory balance training which comprises of visual, vestibular, and proprioceptive manipulation. This study will investigate the effects of early multisensory balance training on visual dependence, balance and gait in subacute stroke patients.

Detailed Description

A total of 80 subacute stroke participants will be randomly assigned to either experimental and control groups. Participants in the experimental group will receive multisensory balance training while those in the control group will maintain their regular care. All participants will be assessed their levels of visual dependence, motor ability, balance and gait, vertigo symptom and activities of daily living before and after intervention program as well as at 3-month follow-up.

Study Groups

Multisensory Balance Training Group

Multisensory balance training manipulate sensory inputs of vision, vestibular and proprioception.

Group Type: EXPERIMENTAL

Multisensory Balance Training

Intervention Type: OTHER

Multisensory Balance training includes 30 minutes per day, 5 days a week for 4 weeks, using visual, proprioceptive, and vestibular manipulations. The exercises involved movements of the eye, head, and body to stimulate the vestibular system, postural control exercises in different positions (feet together, tandem stance, and one leg stance), use of a soft surface to reduce the proprioceptive inputs, and exercises with closed eyes to deprive them of visual cues.

Control Group

Participants in control group maintain their regular activity without any intervention.

Group Type: NO_INTERVENTION

No interventions assigned to this group
