Overview

Poor balance capacity is one of clinical symptoms of stroke patient. The reason of loss balance capacity is motor impairment, as well as a diminished capacity to voluntarily shift body weight or to with stand external pertubations. Postural movement patterns include three discrete control strategies: hip, knee, and ankle strategy. The ankle rocker is an important factor to maintain balance during standing and the ankle strategy restores the center of mass (CoM) to a position of stability through body movement. As a result, effective control of foot motion and ankle stability may decrease postural sway and the risk of fall in chronic stroke.The purpose of this study is to investigate the effects of the insole on balance capacity in chronic stroke.

An important determinant of activities of daily living performance is standing balance. Therefore, poor balance, or postural stability, is significant predictors the risk of fall. After a fall, the patient can experience psychological, physical, social, economic, and sometimes fatal effects. The injuries can reduce the patient's mobility as well as independence and influence quality of life.Patients with chronic stroke wearing functional insoles and sham insoles to challenge balance tests.

Outcomes

Primary Outcomes

Change in Berg balance scale from pre to post-intervention.

The Berg Balance Scale (BBS) was developed to measure balance among older people with impairment in balance function by assessing the performance of functional tasks.

Time frame: up to 30 minutes.

Change in Functional Reach Test(FRT) from pre to post-intervention.

The Functional Reach Test (FRT) is a quick screen for determining risk for falls.

Time frame: up to 10 minutes.

Change in Timed Up and Go (TUG) Test from pre to post-intervention.

Timed Up and Go (TUG) Test was developed to assess mobility.

Time frame: up to 10 minutes.

Secondary Outcomes

Change in Center of pressure (CoP) from pre to post-intervention.

The center of pressure (CoP) measures derived from the foot pressure mat and force plate of Biodex Balance system.
