Assessment of Cognitive Motor Interference in Post Stroke Individuals Under Different Cognitive Load a cross sectional study

Stroke is fairly frequent in older persons and is defined as a neurological impairment of cerebrovascular origin.There is mounting evidence that both the risk and degree of cognitive impairment are increased by stroke. Following a stroke, people with cognitive impairment frequently experience problems with their quality of life and need constant support, which has a significant impact on caregivers and society at large 1

Cognitive impairment following an ischemic stroke is a prevalent and incapacitating outcome 2 . Stroke is one of two leading causes of disability-adjusted life-years worldwide, and post-stroke cognitive impairment (PSCI) has been shown to be common among stroke survivors. Measured within 1.5 years post-stroke, recent reviews and meta-analyses found a pooled prevalence of PSCI of 53.4% and moderate and major PSCI of 36.4–38 and 16%, respectively 3 Given the high correlation between cognition and gait, the cognitive-motor interference (CMI) approach, which employs dual task (DT) walking, may offer a novel methodological technique for assessing brain function in motor cognitive impairment (MCI).  When doing a cognitive and a motor activity simultaneously (dual-task performance), as opposed to performing each task independently (single-task performance), performance in one or both tasks deteriorates. This phenomenon is known as cognitive-motor interference, or CMI.for example, we frequently walk in the community while conversing with a companion or walk through the grocery store while recalling items for purchase 8  Assessments using dual-task (DT) walking allow for the investigation of cognitive function and functional ambulation at the same time, and crucially, they also shed light on the interactions between these two processes. The walking performance metrics measured, gait speed is one of the most commonly examined motor performance variables in DT investigations of post-stroke. Following a stroke, motor and cognitive impairments are commonly seen, but they are typically treated as distinct conditions with minimal evidence connecting them. Subsequent research has demonstrated a connection between executive function (EF) and attention deficits and the impact of dual tasking on gait velocity. Our goal is that this innovative and comprehensive analysis of existing literature will draw attention to the limitations of the experimental setups used today and provide guidance for better dual-task study design and reporting in stroke.However, despite widespread clinical use and functional significance of the Timed Up-and-Go (TUG), the effect of CMI on TUG testing has been less commonly studied in individuals post-stroke.

procedure-

Institutional ethical aprroval wil be obtain after that purposive sampling will be done according to inclusion and exclusion criteria and information sheet will be distributed among the included individuals which will describe the need purpose and nature of the study. after that demographic data will be collected along with the consent form. then instructions such as counting backwards from given number will be given to the individual for assessment of simple cognitive task with the motor task(timed up and go ) and for increasing the complexity of the task individual then instructed to as you have to do serial subtraction three from given number with motor task(timed up and go). after the data collection all the collected data will be analysed using appropriate statistical test.
