We examined the effects of a 12-week combined treatment intervention consisting of whole-body electric muscle stimulation (WB-EMS) and lower-extremity strength exercise on body composition, blood lipid levels, knee pain, and functional ability of patients with obesity and knee pain.
Fourteen patients with obesity and knee pain were randomly assigned to a control group (CON; n = 7) that performed lower-extremity strength exercises and an experimental group (EXP; n = 7) that performed lower-extremity strength exercises combined with WB-EMS. All participants performed the exercise program three days a week for 12 weeks. The WBEMS current strength of the combined treatment was set to a subjective maximum endogenous strength level of 2,500-5000 Hz (medium frequency).
The CON and EXP groups showed similar improvements in body composition, blood lipid levels, Kellgren-Lawrence grading system, and functional ability. However, the Kujala patellofemoral score and isokinetic peak power of the quadriceps femoris improved more in the EXP group than in the CON group.
The 12-week combined treatment intervention of WB-EMS and lower-extremity strength training applied in this study effectively improved pain and knee extension muscle strength in patients with obesity and knee pain.
我们研究了为期12周的联合治疗干预措施，该措施包括全身电肌肉刺激（WB-EMS）和下肢力量训练，对肥胖且伴有膝关节疼痛患者的身体成分、血脂水平、膝关节疼痛及功能能力的影响。
14名肥胖且伴有膝关节疼痛的患者被随机分为对照组（CON；n = 7），该组进行下肢力量训练；以及实验组（EXP；n = 7），该组进行下肢力量训练并结合WB-EMS。所有参与者每周进行3天的训练计划，持续12周。联合治疗的WB-EMS电流强度设定为2500 - 5000赫兹（中频）的主观最大内生强度水平。
CON组和EXP组在身体成分、血脂水平、凯尔格伦-劳伦斯分级系统和功能能力方面显示出相似的改善。然而，EXP组的库贾拉髌股关节评分和股四头肌等速峰值功率比CON组改善得更多。
本研究中应用的为期12周的WB-EMS与下肢力量训练联合治疗干预措施，有效改善了肥胖且伴有膝关节疼痛患者的疼痛和膝关节伸展肌肉力量。
