ABSTRACT
Background: Aging leads to degeneration of joints (osteoarthritis) and decrease in strength of muscles which may affect daily activities. The aim of this study was to compare the functional strength of lower limb in participants with and without osteoarthritis (OA) and to find the relation between strength and intensity of pain.
Methodology: An observational analytical study was conducted on males and females aged 40 to 65 years using convenience sampling. One group included participants with OA knee diagnosed by orthopaedic surgeon and the other group had age and gender matched participants without any complaints of OA knee. People with other severe medical conditions were excluded. Strength of lower limb was assessed using 5 times sit to stand test (5STS) and pain in knee was assessed using NPRS among participants with OA. Data was analysed using SPSS V20. Level of significance was kept at 5%.
Result: 101 participants participated. Mann Whitney test was used to analyse difference in 5STS between individuals with and without OA which showed statistically significant differences (U=85.5, p=0.0001). Spearman’s correlation r=0.44, p=0.001) was found between pain and lower limb strength in individuals with OA knee.
Conclusion: Participants with osteoarthritis knee have decreased lower limb strength compared to participants without OA of the knee. There was moderate correlation between functional strength and intensity of pain in people with OA.
Key words: Osteoarthritis knee, lower limb strength, 5STS
