Purpose: To explore the feasibility and efficacy of using a power training exercise programme for the quadriceps femoris (QF) in elderly women with knee
osteoarthritis (OA). Method: A one-group quasi-experimental design with pre- and post-intervention measurements was conducted on 17 older adult
women with knee OA pain. A bilateral QF exercise programme (24 sessions over 8 weeks) consisting of 3 series of 10 repetitions of flexion-extension as
fast as possible at 40% of their one-repetition maximum (1RM) was performed in an outpatient physiotherapy clinic. The primary outcome measures were
the knee function and associated problems using the Knee injury Osteoarthritis Outcome Score (KOOS) questionnaire and the weekly mean pain score from
pain diaries using a visual analogue scale (VAS). QF strength (QFS), power (QFP) and work (QFW) were measured with an isokinetic dynamometer as
secondary outcomes. Results: Significant improvements (p < 0.05) were noted on the five categories of the KOOS. Significant decrease (p < 0.01)
was noted in pain intensity on VAS. QFP and QFW increased significantly on both sides (p < 0.05). Exercise compliance was 99.5% for 16 participants.
Conclusions: A short power-training exercise programme is a feasible training modality for patients with knee OA, and significant functional improvements
can be achieved. Further studies must be conducted to better understand the effects of the programme parameters and the generalizability of the findings
