NCT04702815 | Completed

• 1 other identifier: N201912127
• Study Type: observational
• Target: 100

Brief Summary

This cross-sectional study aims to investigate the prevalence of post-stroke visual dependence, and the effects of visual dependence on balance and gait. It also determines whether visual dependence could differentiate stroke patients with a history of falls from without.

Conditions

Stroke; Balance; Distorted; Gait, Unsteady

Outcome Measures

Primary Outcomes (3)

• Perceived visual dependence

  Perceived visual dependence will be assessed using a computerized Rod and Disc Test (RDT). Participants will adjust a tilted rod to their subjective visual vertical with rotating visual background. The error (degrees) between subjective visual vertical and gravitational vertical will be measured and represented as the level of visual dependence. Higher error indicates higher level of perceived visual dependence.

  Baseline

• Postural visual dependence

  Postural sway will be measured using an accelerometer attached on the lower back when participants are looking at blank wall, eyes closed and looking at rotating visual background. Greater postural sway in conditions with eyes closed and rotating visual background corresponding to looking at blank wall represents the higher level of postural visual dependence.

  Baseline

• A history of falls

  Any falls in the past year (n). Fall is defined by the inadvertently coming to rest on the ground, floor or other lower level, excluding intentional change in position to rest in furniture, wall or other objects. More than once fall is identified as faller.

  Baseline

Secondary Outcomes (9)

• Physical impairment of paretic leg and foot

  Baseline

• Five Times Sit to Stand Test

  Baseline

• Berg Balance Scale

  Baseline

• Timed Up and Go test

  Baseline

• Modified Clinical Test of Sensory Integration and Balance

  Baseline

Eligibility Criteria

• Age: 20 Years - 80 Years
• Sex: all

Study Population

Chronic stroke patients with the first stroke will be recruited from the 3 departments of physical and rehabilitation medicine, regional hospitals.

You may qualify if:

• \) first stroke with 20-80 years of age

• \) can walk independently at least 10 meters without any walking devices and orthosis
• \) normal cognitive function with scoring more than 24 on the Mini Mental State Examination scale
• \) can understand and follow commands
• \) can give informed consent

You may not qualify if:

• \) other neurological disorders which could affect balance assessment
• \) cerebellar stroke
• \) diagnosis with central or peripheral vestibular diseases.
