Musculoskeletal conditions of lower extremities are the most common cause of impairments and disabilities in elder population. With increasing age, disability increases and also physical performance reduces. Limited studies have been found on elderly in Indian population identifying the correlation of physical performance like strength and dynamic balance with their functional ability. Studies have reported reduction in functional ability in elderly after COVID lockdown. Few studies were found to report weak correlation between self-reported functional ability and objectively assessed physical performance whereas some studies showed strong correlation between the two. Inconsistent study results and the gap in the knowledge about the perception of the functional ability and actual physical performance in elderly makes it necessary to find out the correlation of self-reported functional ability with objective assessment of physical performance in elderly with lower limb dysfunctions especially in this COVID era. After the approval from the ethical committee, this cross sectional study with purposive sampling will be carried out. Participants with both unilateral and bilateral lower limb dysfunctions will be included as per inclusion-exclusion criteria. Written informed consent will be taken prior to commencement of the study from the patient. They will be instructed to fill a self-reported Lower Extremity Functional Scale(LEFS) to assess their functional ability. For physical performance they will be assessed for lower limb strength(using 30 Seconds Chair Stand Test) and dynamic balance(using 8 Foot Up and Go Test). Data obtained from these tests will be analysed for correlation between functional ability (LEFS score) with strength(number of full chair stands) and dynamic balance( time in seconds) using Pearson’s correlation coefficient. Extent of correlation(if any) will be carried out with regression analysis.
