Effect of the Combination of Action Observation Training and Rhythmic Auditory Stimulation on Balance and Functional Recovery of Sub-acute Stroke Patients: A Randomized Controlled Trial

Stroke is a serious global health issue and it is currently the fifth greatest cause of disability and the fourth major cause of death in India. Goa is recording a rise in the number of stroke cases. Following a stroke, alignment, stability, symmetry, and dynamic balance are all impaired, causing postural control and balance problems. The gait and dynamic balance abilities of stroke patients are extremely important because of their close relation with daily activities. Rhythmic Auditory Stimulation (RAS) is a typical therapeutic approach which uses auditory rhythmic cues in the form of beats of a metronome to promote auditory-motor entrainment of rhythmic movements. The beats are provided by using metronome apps on smartphone which are often freely available or at a relatively low cost, making it a cost-effective solution, thereby making this approach more efficient and feasible. Another effective technique that can be incorporated into the rehabilitation program is the Action Observation Training (AOT) which involves observing actions and constantly imitating and practicing them. Therefore, this study aimed to evaluate the effects of the combination of RAS and AOT on balance and functional recovery of subacute stroke patients and to assess the changes in the levels of self-confidence to perform activities without losing balance in patients with subacute stroke.
