Abstract
BACKGROUND/AIM: Different manual therapy techniques and conservative therapy have been used separately for alleviation of pain and improvement of physical function in patients with knee osteoarthritis (KOA). However, no study has reported the effect of combination of these treatment modalities in the management of KOA. Our aim was to test the feasibility of the study design and to compare the effect of end-range Maitland mobilization to conservative therapy in KOA. PATIENTS AND METHODS: Fifteen patients (conservative therapy group: CG) received conservative therapy alone, fifteen patients (Maitland plus conservative therapy group: M+CG) received additionally end-range Maitland mobilization during the 3-week study period. Outcomes were pain intensity, measured with visual analogue scale (VAS) in general and during functional activities, passive range of motion (PROM) and peak muscle force during knee flexion and extension, Timed Up and Go test and 6-Minute Walk Test (6MWT). RESULTS: All outcomes improved significantly in both groups. Magnitude of changes was significantly greater in M+CG compared to CG regarding all VAS pain scores, flexion PROM of both knees, right hamstring peak muscle force and 6MWT. CONCLUSION: With few modifications, this study design seems feasible for the comparison of end-range Maitland mobilization with conservative therapy in KOA. Moreover, end-range Maitland mobilization in addition to conservative therapy appeared more effective in relief of pain and improvement of functional status than conservative therapy alone in KOA.
