Is there any association between dominant lower limb and osteoarthritis- A Cross sectional study

Abstract

Background: Osteoarthritis (OA) is second most common degenerative arthritis with 56.6% affection in rural areas where as 32.6% in urban areas in India.Dominant lower limb is the leg used to manipulate objects or to lead out movement. Primary predisposing factor of degenerative arthritis is wear and tear which might correlate with dominance of limb. Methodology: Total 180 subjects were screened, out of which 61 subjects with bilateral osteoarthritis and 40 subjects with unilateral osteoarthritis were selected as per inclusion criteria. Dominant leg was noted by asking Subjects to perform 2 tasks 1) Kicking Vestibular ball 2) Stepping up stepper, between this two-task cognitive distraction were implemented. then co-relation of osteoarthritis knee and dominant side was analysed. Results: From statistical analysis of above study, it was found that there is significant (p<0.05) association between dominant limb and osteoarthritis in unilateral osteoarthritis subjects and moderate 60%-70% association of dominant leg and osteoarthritis knee in bilateral osteoarthritis. Conclusion: From above study it is concluded that chances of osteoarthritis in dominant limb is moderately high than non-dominant limb in unilateral and bilateral osteoarthritis
