Angular biofeedback device for sitting balance of stroke patients

Area of Science:

• Neurology
• Rehabilitation Medicine
• Biomedical Engineering

Background:

• Impaired sitting balance is a common and debilitating complication following stroke.
• This significantly impacts patient recovery, independence, and overall quality of life.
• Conventional physical therapy aims to address balance deficits but can be time-consuming.

Purpose of the Study:

• To evaluate the efficacy of angular biofeedback as an adjunct to conventional physical therapy for stroke patients with impaired sitting balance.
• To compare the outcomes of patients receiving biofeedback-assisted therapy versus conventional therapy alone.

Main Methods:

• A study involving 24 patients in the biofeedback group and 13 in the control group.
• The biofeedback group received angular biofeedback training alongside conventional physical therapy.
• Sitting balance, number of biofeedback signals, and duration of balanced sitting were measured at baseline, after 10 days, and at discharge.

Main Results:

• 75% of the biofeedback group achieved sitting balance after 10 days, compared to 15.4% in the control group (P < .001).
• The biofeedback group showed significantly shorter mean training time to achieve sitting balance (P < .001).
• Mean rehabilitation periods were shorter for ambulatory patients in the biofeedback group (9.45 weeks) versus the control group (13.83 weeks) (P = .049).

Conclusions:

• Angular biofeedback is a valuable tool for improving sitting balance in stroke rehabilitation.
• It facilitates earlier postural trunk control, enhancing recovery.
• This intervention serves as a useful adjunct to conventional physical therapy for stroke survivors.
