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).

  • radiographic diagnostic of Grade 2 or 3 knee osteoarthritis.

排除标准

  • a body mass index higher than 40 Kg/m
  • a diagnosis of hip, ankle, or toe osteoarthritis.
  • the use of crutches for locomotion.
  • participation in a strength-training programme or physiotherapy treatment for knee osteoarthritis in the past six months.

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).)
