Comparative Effects of Dual Task and Proprioceptive Neuromuscular Facilitation on Balance ,Cognition and Motor Function in Chronic Stroke Patients

The aim of this study is to compare the effect of dual tasking and proprioceptive neuromuscular facilitation on balance, cognition and motor function in chronic stroke patients. It will be randomized clinical trial.

Stroke is the major cause of disability and mortality worldwide. A stroke is defined as an abrupt neurological outburst caused by impaired perfusion through the blood vessels to the brain. Every year the number of patients affected by stroke is rising thereby putting extra pressure on socioeconomic conditions in developing countries. Major complications of stroke include hemiplegia leading to upper limb dysfunction along with gait abnormalities. This study will be conducted to determine the effects of proprioceptive neuromuscular facilitation exercises versus dual-task training on balance, cognition, and motor function in chronic stroke patients. The randomized clinical trial will be conducted, participants will be selected through Non-probability convenience sampling technique and then randomly allocated into two treatment groups.

Dual tasking utilizes a task-specific approach to balance training, applying repeated exposure to unpredictable mechanical perturbations that mimic balance disturbances experienced in daily life.

Proprioceptive neuromuscular facilitation (PNF) is a therapeutic approach that uses cutaneous, proprioceptive and auditory input to produce functional improvement in motor output.

Dual-task training is an emerging task-specific intervention that aims to improve reactive balance control after destabilizing perturbations in a safe and controlled environment. Dual tasking is given by therapist in unexpected directions to challenge patients reactive balance. In this study dual tasking will be given manually and on hurdles. Daily 45 mins of exercise sessions of dual-task training like walking with talking , walking with a filled cup of water, walking with looking on clock performed for total eight weeks and 5 days a week.

PNF involves both stretching and contracting (activation) of the muscle group being targeted in order to achieve maximum static flexibility, along with its D1&D2 flexion/extension patterns to improve dynamic flexibility and thus improving balance and coordination. total 8 weeks session will be given to patients. 45 mins session/each day for 5 days a week.

Berg balance scale is used to find and access the balance issues. This scale consists of 14 task which related to everyday life. Each function rates from 0 (worst) to 4 (best) along a dependence and independence sequence. In this test, we gradually reduce the base of support from sitting and standing to single-leg stance, assess a subject's capacity to sustain positions or movements of increasing difficulty. One's ability to change position is also evaluated(

MoCA scale is used to meaured cognition .Scoring is based on direct observation of performance. Scale items are scored on the basis of ability to complete the item using a 3-point ordinal scale where 0=cannot perform, 1=performs partially and 2=performs fully. The total possible scale score is 226.

The Fugl-Meyer Assessment of Lower Extremity (FMA-LE) is a widely used and recommended scale for evaluation of post-stroke motor impairment. It is designed to assess motor functioning, balance, sensation and joint functioning in patients with post-stroke hemiplegia. The scale is comprised of five domains and there are 155 items in total
