Effect of Russian Current Stimulation for Anterior Tibial Group on Postural Stability and Risk of Falling in Patients With Stroke

Обзор

This study aimed to examine the effect of Russian current stimulation on Anterior tibial group on postural stability and risk of falling in patients with stroke.

Подробное описание

Stroke is the second leading cause of death globally and the main cause of disability, with ischemic strokes accounting for about 87% of cases. In 2010, over 11 million ischemic strokes occurred, predominantly in low and middle-income countries, leading to approximately three million deaths. Hemorrhagic strokes account for 13% of cases.

Egypt, with an estimated population of 85.5 million, has a high stroke prevalence of 963 per 100,000 inhabitants. Postural imbalance is a common limitation, affecting 83% of acute stroke patients, and falls are frequent across all stages of recovery, with rates as high as 73% within six months post-discharge. Even in chronic stroke patients, the fall risk remains elevated compared to age-matched controls. Postural imbalance impacts quality of life, and rehabilitation is vital for regaining independence in daily activities.

Up to 30% of stroke survivors experience significant permanent disabilities, and 20% require rehabilitation. Motor impairments, particularly in the lower limbs, limit daily activities, community participation, and quality of life. Poor lower-limb muscle performance affects balance, gait, and functionality, but interventions like Russian current have shown effectiveness in improving walking performance and motor recovery in chronic stroke survivors.

Вмешательства

• Другое Russian Current Stimulation for Anterior Tibial Group
  Parameters were adjusted as the following frequency of 2.5 kHz and 50 bursts per second with 50 pulses per burst. The stimulus was applied for a 10 seconds "on" period followed by a 10 seconds "off" period for total treatment time 20 minutes.
• Другое Placebo Russian Current Stimulation for Anterior Tibial Group
  Placebo Russian current stimulation was applied to the anterior tibial group without active current for 20 minutes.
• Другое Selected physical therapy exercise for both limbs
  The selected physical therapy exercise for both limbs was applied for 40 minutes, including passive, active assisted and active range of motion exercises, stretching of spastic muscles, strengthening of weak muscles (anterior tibial group), and finally functional mobility exercises.
