目的:探讨经皮神经电刺激(TENS)在减少障碍、实施运动疗法、促进运动疗法的效果。专注于身体活动。
方法:单,参与者失明,具有前置设计的随机对照试验(RCT)设置:单机构,骨科门诊参与者:参与者膝盖疼痛至少3个月(N=63,年龄≥50岁),并被随机分配到TENS(N=21),运动(N=23),或联合(N=19)组。
方法:为参与者提供4周的干预:TENS组使用可穿戴TENS设备,进行指定锻炼的锻炼小组,并结合TENS和锻炼组的小组表演活动。
方法:主要结局指标是体力活动(PA)。次要结果指标是6分钟步行测试(6MWT);定时上行测试(TUG);爬楼梯;使用视觉模拟量表在6MWT时的膝盖疼痛,TUG,和爬楼梯;以及患者报告的膝关节疼痛随时间的变化。
结果:在干预前后,TENS中的光强度PA时间(LPA),锻炼,合并组为735.62±68.82vs.714.21±73.06(p=0.061),733.05±103.90vs.700.31±90.33(p=0.057),和710.09±62.98vs.685.22±58.35(p=0.049),分别,合并组显着减少。在干预前后,所有组均观察到膝关节疼痛和爬楼梯的显着改善。
结论:使用TENS的组表现出早期减轻膝关节疼痛的改善效果,当与运动疗法结合时,减少在光强度活动中花费的时间,如久坐行为。因此,TENS与常规运动疗法结合使用有可能减少引入运动疗法的心理障碍。它还促进和确保运动疗法的安全实施和持续。
OBJECTIVE: To investigate the effect of transcutaneous electrical nerve stimulation (TENS) in reducing barriers to the implementation of exercise therapy and promoting exercise therapy, focusing on physical activity.
METHODS: A single, participant-blinded, randomized controlled trial (RCT) with a pre-post design SETTING: Single-institution, orthopedic clinic PARTICIPANTS: Participants had knee pain for at least 3 months (N=63, ≥50 years of age) and were randomly assigned to the TENS (N=21), exercise (N=23), or combined (N=19) group.
METHODS: Participants were provided with 4 weeks of intervention: the TENS group using a wearable TENS device, exercise group performing designated exercises, and combined group performing activities from the TENS and exercise groups.
METHODS: The primary outcome measure was physical activity (PA). The secondary outcome measures were 6-minute walk test (6MWT); timed up-and-go test (TUG); stair climbing; knee pain using the visual analog scale at 6MWT, TUG, and stair climbing; and patient-reported changes in knee pain over time.
RESULTS: At pre- and post-intervention, light-intensity PA time (LPA) in the TENS, exercise, and combined groups was 735.62±68.82 vs. 714.21±73.06 (p=0.061), 733.05±103.90 vs. 700.31±90.33 (p=0.057), and 710.09±62.98 vs. 685.22±58.35 (p=0.049), respectively, with a significant decrease in the combined group. Significant improvement in knee pain and stair climbing was observed in all groups pre- and post-intervention.
CONCLUSIONS: The group using TENS showed improved effects of early reduction in knee pain and when combined with exercise therapy, a reduction in time spent in light-intensity activities such as sedentary behavior. Thus, the use of TENS in combination with conventional exercise therapy has the potential to reduce psychological barriers to the introduction of exercise therapy. It also promotes and ensures the safe implementation and continuation of exercise therapy.
