Effect of Strength Training of Non-paretic Upper and Lower Limb With or Without Mirror Therapy on Motor Function Recovery of the Pareytic Side in Stroke Patients.
Effect of Strength Training of Non-paretic Upper and Lower Limb With or Without Mirror Therapy on Motor Function Recovery of the Pareytic Side in Stroke Patients.
The aim of this study is to find the effects of strength training with or without mirror therapy of non-paralytic upper limb for functional activities and in lower limb for gait pattern, balance and stability, and ADLs of paralytic side in patients with acute and sub-acute stroke. A randomized controlled trial that will include total 44 participants .The control group will undergo usual rehabilitation training along with strength training. The trial group will undergo strength training and mirror therapy of NHS on the basis of usual rehabilitation training. For the control group, training time will be 30 minutes, once a day, 3 days a week for 8 weeks. IN trial group, training time will be 30 minutes therapy, once a day, 3 days a week for 8 weeks. were allowed to rest for 3-5 min during each training. Data collected will be analyzed through SPSS 25.
Stroke is defined as rapidly developing clinical signs of focal or global cerebral function disturbance that lasts more than 24 hours or leads to death, with no other apparent cause than that of vascular origin. Hemiplegia shows one side of the body paralysis involving one upper and one lower extremity. The term hemiplegia is often used generically to refer to the wide variety of motor problems that result from stroke.There are several stroke rehabilitation strategies for UL motor impairment including strength training and mirror therapy.
The idea is to re-educate the brain through a simple task, in which the individual performs a series of movements with the healthy arm, which is reflected in the mirror as if it was the injured arm. In this way, the reflex in the mirror of the healthy arm tricks the brain in believing that the injured arm is functioning as it should before the stroke. Isokinetic strengthening may provide motor and functional improvement in paretic upper extremity among patients with post-stroke hemiplegia. This strategy makes use of the brain's adaptability to enhance motor function after a stroke .
Monika Ehrensberger et al (2019) in a study concluded potential effectiveness of mirror-aided cross-education was undertaken and results portray that, in the case of training isometrically, cross-education was not augmented by mirror therapy. (The effectiveness of strength training of the NHS is evidenced in terms of promoting recovery in patients with stroke experiencing balance, mobility, and muscle strength of the paretic side .
Chenlan Shao et al (2022) conducted his study on the effect of strength training of the non-hemiplegic side (NHS) on balance function, mobility, and muscle strength of patients with stroke. He concluded that Strength training of the NHS can promote recovery of balance, mobility, and muscle strength of the paretic side of patients with stroke.
Harris et al demonstrated that leg weakness develops on the non hemiplegic side (NHS) in the first week after acute stroke. This decline in NHS muscle strength must not be ignored in patients with stroke, because it is highly associated with functional performance, and it can be used as an independent predictor of short-term functional gain and outcomes after stroke.
The previous study investigated the feasibility and potential effectiveness of mirror-aided cross-education compared with cross-education alone in post stroke upper limb recovery only. In addition, previous studies, mirror therapy, and contralateral strength training have shown promising results individually, but their direct comparison for both upper and lower limbs remains under-explored in the literature.
The rationale for this study stems from the critical need to understanding the effectiveness of only mirror-therapy performed solely versus mirror-aided treatment coupled with strength training in enhancing motor functionality across both upper and lower limbs can significantly impact rehabilitative protocols.
This research could uncover potential synergies between the two interventions, presenting an opportunity to develop cost effective novel combined approaches that capitalize on their respective strengths. Ultimately, the study's findings have the potential to advance the field of neuroplasticity aided neurorehabilitation and contribute to improved quality of life for individuals dealing with hemiplegia.
