Correlation between sit-to-stand ability, dynamic balance, gait speed, and quality of life in stroke population: a non-randomized pilot study

Abstract

Abstract Background “Sit to stand” being a prerequisite for walking, the inability of patients to perform it can result in institutionalization, impaired functioning and mobility in activities of daily living. There was a need to find out whether “sit to stand” ability correlates with gait speed, dynamic balance, and quality of life in stroke patients. It is a pilot study in which sixteen sub-acute and chronic stroke (˃ 6 months) patients aged 45 to 65 years with the ability to walk at least 10 m, Mini Mental State Examination (MMSE) score ˃ 27 were included. Patients with musculoskeletal impairments of lower extremity which would affect walking were excluded from the study. Each patient performed five times sit to stand (5TSTS) from a standard chair and time taken was recorded. Timed up and go (TUG) test and 10-m walk test (10MWT) were used to measure the dynamic balance and gait speed respectively. Stroke Adapted Sickness Impact Profile-30 (SASIP-30) scale was used to determine the quality of life of the patients. Results Correlation between the outcomes of the variables was analyzed using Pearson correlation co-efficient. The 5TSTS scores showed strong positive correlation to TUG (r = 0.823, P < .000) and SASIP-30 (r = 0.841, P < .000). However, moderately strong negative relationship was found between 5TSTS and gait speed (r = −0.639, P < .008). Conclusion The study concludes that change in the 5TSTS performance can affect motor functions like dynamic balance and gait as well as quality of life. Exercise training focusing on sit-to-stand ability may also influence activities of daily living (ADLs) after stroke.
