Study Overview
Brief Summary
Introduction: Knee osteoarthritis (KOA) is the biggest cause of pain and disability worldwide. As a non-pharmacological approach, ventosatherapia has been used to control pain, improve function and quality of life. However, there is a lack of high-quality scientific evidence regarding its effects on this condition. Objective: To evaluate the effects of dry cupping on pain, function and quality of life in women with KOA. Methods: This is a randomized, blinded placebo-controlled protocol. 62 women diagnosed with KOA will be recruited, based on the clinical criteria of the American College of Rheumatology, who will be randomly divided into two groups (31 per group): dry cupping and dry cupping sham.
Detailed Description
The intervention will be carried out for 15 minutes, twice a week, for 6 consecutive weeks, totaling 12 sessions. Both groups will be evaluated in 4 moments: before the intervention (T0), after 3 weeks of interventions (T3), at the end of the protocol (T6) and 4 weeks after the end of the interventions (follow-up - T10). The analyzed outcomes will be: Primary - pain (numerical pain scale); Secondary - Physical function (WOMAC; tests of going up / down stairs, brisk walking in 40 m and sitting / rising from a chair in 30 s), quality of life (SF-36) and global perception of the effect

Masking Description
To avoid any type of selection bias, the confidential allocation method will be through opaque envelopes, sealed and numbered consecutively. The randomization process will be carried out by an independent researcher who will not be involved in other study procedures. The group in which the participant will be allocated will be revealed to the researcher responsible for the consultations prior to the first intervention.

Arms & Interventions
Dry cupping group
The dry cupping will be applied with a force of two suctions generating a negative pressure on the skin during the time of 15 minutes.
Intervention: Dry cupping therapy (Other)
Dry cupping sham group
The dry cupping sham group will receive the same procedures as the dry cup group, with the difference that the negative pressure imposed after application will be released in a few seconds.
Intervention: Dry cupping therapy (Other)
Outcomes
Primary Outcomes
Change from Numerical Rating Scale (NRS)
Time Frame: baseline, 3 ,6 and 10 weeks after.
Subjective measure in which individuals rate their pain on an eleven-point numerical scale. Such scale will be positioned in front of the participant and will vary from 0 to 10 points, with 0 being the complete absence of pain and 10 being the worst pain imaginable by the individual
Secondary Outcomes
- Change from Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC)(baseline, 3 ,6 and 10 weeks after.)
- Change from 30-second Chair Stand Test(baseline, 6 and 10 weeks after.)
- Change from 8-step Stair Climb Test(baseline, 6 and 10 weeks after.)
- Change from 40m Fast Paced Walk Test(baseline, 6 and 10 weeks after.)
- Change from Short-Form 36 quality of life(baseline, 6 and 10 weeks after.)
- Change from Global Perceived Effect(baseline, 3, 6 and 10 weeks after.)
- Change from use of analgesics and anti-inflammatories(baseline, 3, 6 and 10 weeks after)
- Change from expectation with treatment after the intervention protocol .(baseline and 10 weeks after)
