简要总结
- The purpose of this study is to determine the effects of low-level laser therapy in combination with neuromuscular electrical stimulation on neuromuscular (muscular strength and morphology) and functional parameters (pain and functional tests) in elderly with knee osteoarthritis.
- The hypothesis is that the association of low-level laser therapy with neuromuscular electrical stimulation could reduce joint pain associated with the inflammation and consequently potentiates the effects of electrical stimulation on the muscular system.
详细描述
- Participants was randomized into one of three intervention groups (intervention period = 8 weeks after a 4 weeks control period in all groups).
- Electrical stimulation group (18-32 min of pulsed current, stimulation frequency of 80Hz (Hertz), pulse duration of 200μs and stimulation intensity fixed near to maximal tolerated),
- Laser group (low-level laser therapy dose of 4-6J (Joules) per point, six points at the knee joint)
- Combined group (electrical stimulation and low-level laser therapy).

结局指标
主要结局
Torque change
时间窗: Torque was measured 3 times during the study: baseline (week -4), before intervention (week 0) and post intervention (week 9).
Torque is an expression of the muscular strength and was assessed by dynamometry.
次要结局
- Muscular architecture change(Architecture was measured 3 times during the study: baseline (week -4), before intervention (week 0) and post intervention (week 9).)
