Footwear modifications and physical therapy in knee osteoarthritis patients: effects on WOMAC scores and associated walking speed
摘要
Osteoarthritis is the most common condition that results in impairment and has the greatest impact on the medial compartment of the knee joint. To lower medial knee loading (MKL), which helps to lessen discomfort and other symptoms, a number of footwear adjustments are used. This study aimed to compare the effects of two different types of footwear insoles on pain and physical function of knee osteoarthritis patients and their association with walking speed.
MethodsA double-blinded randomized clinical trial (RCT) was conducted, with trial registration number NCT04536519. Data were recorded at baseline, and after 8, 16, and 24 weeks from 60 medial knee osteoarthritis patients after dividing into two groups: group A received a lateral heel wedge insole (LHWI) with medial arch support, while group B only received lateral heel wedge insole (LHWI). Data was analyzed using one-way analysis of variance (ANOVA) and repeated measures ANOVA.
ResultsBoth groups showed significant reduction in pain and improved physical function and walking speed but more pronounced results were recorded for group A (lateral heel wedge insole with medial arch support). Pearson correlation showed that the Western Ontario and McMaster University Osteoarthritis Index (WOMAC) pain and physical function scores were inversely correlated to walking speed of patient.
ConclusionThe study concluded that patients using LHWI with medial arch support insole showed better improvements in knee OA-related pain and physical function as compared to individuals using LHWI alone. Also, the WOMAC pain and physical function scores were negatively correlated to walking speed of individual which shows that patients having low knee pain and less difficulty in physical function walk with high speed.
