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).
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.
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.
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.
探讨对患有膝关节骨关节炎（OA）的老年女性使用股四头肌（QF）力量训练运动计划的可行性和有效性。
对17名患有膝关节OA疼痛的老年女性进行了一项采用干预前和干预后测量的单组准实验设计。在门诊物理治疗诊所进行了一项双侧QF运动计划（8周内进行24次训练），包括以其一次重复最大值（1RM）的40%尽可能快地进行3组，每组10次屈伸运动。主要结局指标是使用膝关节损伤骨关节炎结局评分（KOOS）问卷评估的膝关节功能及相关问题，以及使用视觉模拟量表（VAS）从疼痛日记中得出的每周平均疼痛评分。使用等速测力计测量QF力量（QFS）、功率（QFP）和功（QFW）作为次要结局指标。
KOOS的五个类别均有显著改善（p<0.05）。VAS疼痛强度显著降低（p<0.01）。两侧的QFP和QFW均显著增加（p<0.05）。16名参与者的运动依从性为99.5%。
短期力量训练运动计划对膝关节OA患者是一种可行的训练方式，并且可以实现显著的功能改善。必须进行进一步研究以更好地了解该计划参数的效果以及研究结果的普遍性。
