task-oriented balance training with sensory integration

Conditions: Stroke Patient

Summary: objectives of this study are to determine the effect of task-oriented balance training on balance, postural stability and mobility in stroke patients, to determine the effect of task-oriented balance training with sensory integration on balance, postural stability and mobility in post stroke patients and to compare the effect of balance training with and without sensory integration on balance, postural stability and mobility in stroke patients. study design is randomized control trial. sample size is 60 calculated through open epi tool. sampling technique is non-probability purposive sampling technique then randomization through sealed envelope method into control and experimental group. duration of study is 6 months. study setting rafsan stroke center peshawar.

stroke is the leading cause of high levels of morbidity and long-term functional disability in adults. stroke is a clinical syndrome characterized by rapidly developing symptoms and/or signs of focal and at times global (for patients in coma) loss of cerebral functions, with symptoms lasting more than 24 hours or leading to death with no apparent cause other than that of vascular origin. the incident of stroke is rising steadily, according to estimates by the who, stroke accounted for 5.7 million deaths and 16 million first-time events in 2005 and these numbers may reach 7.8 million and 23 million by 2030, respectively. stroke is the second leading cause of preventable death worldwide and the fourth leading cause of lost productivity, as measured by disability-adjusted life years. world health organization reported that total mortality due to stroke in pakistan was 78512.2 who estimate for the year 2020 predict that stroke will remain the second leading cause of death after ischemic heart disease, both in developing and developed countries. annually, fifteen millions people worldwide suffer a stroke. of these, five million dies and another five million are left permanently disabled, placing a burden on family and community. when balance impairment is affected early after stroke, performance of simple and complex tasks become difficult which results in their functional mobility. impaired balance has also been identified as the strongest predictor of falling, which in turn is related to fear of falling, limited activity and quality of life. thus, this vicious cycle of balance disability is continued, resulting in delaying the recovery process of stroke rehabilitation. sensory impairment reduces sensory processing ability, thereby reducing motor and balance responses. muscle weakness causes a muscular imbalance between the paretic and non-paretic sides, resulting in weight-bearing imbalance and an asymmetric posture during standing. as a result, functional activities such as sit-to-stand, standing, walking, and balance control are limited. different interventions were used for the restoration of functional activities mobility and balance in post-stroke patients. a task-oriented approach is one method used to overcome limited functional activities. previous studies have reported that the application of this approach was effective in improving functional activities in stroke patients. shumway-cook and woollacott reported that movements are generated by the interaction of various systems in the brain, organized with a focus on goals, and limited by the environment. because the task-oriented approach focuses on goals and the environment, it may be a suitable method for overcoming limited functional activities. the effective integration of visual, somatosensory, and vestibular information is necessary to maintain balance ability during functional activities. stroke patients rely highly on visual information due to a lack of somatic and vestibular senses. therefore, it is necessary to restore sensory integration in stroke patients through the manipulation of somatic, visual and vestibular senses. task-oriented balance training is proved to be effective for improvement of balance in stroke patients. sensory balance training has also shown a beneficial effect on balance and mobility of stroke patients. there is limited evidence on the effects gained by task-oriented balance training with altered sensory input this study aims to determine the effects gained by combining the task-oriented balance training with sensory integration.
