Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
One intervention group will receive transcutaneous electrical nerve stimulation (TENS) application before therapeutic exercise. This stimulation will last 40 minutes, and will be carried out 3 times per week, in a total of 4 weeks. Conventional TENS parameters will be used.
The other intervention group will have ear acupuncture sessions before therapeutic exercise. This therapy will be carried out once a week, in a total of 4 weeks, and each session will last 15 minutes. Conventional puncture ear points will be used.
Both intervention groups will have therapeutic exercise after the specific therapy intervention of each group. Therapeutic exercise sessions will last 40 minutes and will be carried out 3 times per week, in a total of 4 weeks.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Subjects will be recruited from the waiting list for physiotherapy from University Hospital of Federal University of Juiz de Fora.
At first, a blinded physiotherapist evaluated the subject in order to know if it was eligible for inclusion in this study. After this evaluation, the participant will be randomly allocated into intervention and control groups. The allocation procedure will be carried out by a sealed opaque envelope.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Subjects will be randomly allocated in each treatment group according to the non-stratified randomization. The simple randomization procedure used was dice rolling. Number 1 and 4 was control group. 2 and 5 was ear acupuncture intervention and 3 and 6 was transcutaneous electrical nerve stimulation.
Masking / blinding
