Brief Summary

Introduction and Purpose: Compression is a tactile stimulus that can reduce the perception of pain by stimulating tactile skin receptors and the speed of nerve conduction. It is highly associated with cryotherapy and other non-pharmacological physical agents without musculoskeletal pain control. However, there is still a lack of evidence on its possible effects on the modulation of this type of pain. This study will evaluate the effect of compression by elastic bandages, on pain and on the function of belonging with knee osteoarthritis (KO). Methodology: A randomized, blinded controlled clinical trial will be conducted. Individuals with KO (n = 90; both sexes; between 40 and 75 years old), will be allocated into three groups (n = 30 / group): Compression (submitted to compression by elastic bandage on the affected knee, 20 min, in 4 days consecutive); Sham (submitted to the same protocol with elastic bandage, but without compression); and Control (waiting list, without intervention). All will be taken one day before the start and one day after the last intervention. They will also be adopted in the 12th and 24th weeks after the intervention. The main outcome will be the pain intensity (Visual Analogue Scale). The Western Ontario \& McMaster Universities Osteoarthritis (WOMAC) physical function questionnaire, physical function tests (step test, sit and stand test in 30s, 40m accelerated walk test), and the perception scale global change (GRC). Data analysis: SPSS 24.0 software will be used for descriptive analysis and performance of Kolmogorov-Smirnov tests, two-way ANOVA and multiple comparison tests. A 95% confidence level and a 5% significance level will be adopted.

Outcome Measures

Primary Outcomes (2)

  • Change from baseline - Visual Analog Scale (VAS)

    The scale will be made available visually to the individual so that he can classify the intensity of the average pain relative to the last week, and also before and after the performance of each functional physical test. The scale will vary from 0 to 10 cm, with 0 being the complete absence of pain, and 10 being the maximum pain intensity reported by the individual. The 1.75cm reduction will be considered an MDCI.

    Baseline, immediately after intervention and follow-up evaluations of 12 and 24 weeks.

  • Change from baseline WOMAC (Western Ontario e o McMaster Universities Osteoarthritis Index) - Pain scale

    Self-report questionnaire, designed to assess problems experienced by individuals with lower limb OA, in the last 72 hours. The volunteer will be asked to answer 24 questions, which comprise three domains: pain, stiffness and physical function. The scores for the items are expressed using the Likert scale, classified as: none = 0, low = 25, moderate = 50, severe = 75 and very severe = 100. Higher scores indicate higher levels of pain, stiffness and physical dysfunction . The reduction of 8.74 points in the pain domain, from the baseline, will be considered an MDCI.

    Baseline, immediately after intervention and follow-up evaluations of 12 and 24 weeks.

Secondary Outcomes (5)

  • Change from baseline WOMAC (Western Ontario e o McMaster Universities Osteoarthritis Index) - stiffness and physical dysfunction scales

    Baseline, immediately after intervention and follow-up evaluations of 12 and 24 weeks.

  • Sit and stand test - 30 seconds

    Baseline, immediately after intervention and follow-up evaluations of 12 and 24 weeks.

  • Step test

    Baseline, immediately after intervention and follow up evaluations of 12 and 24 weeks.

  • 40 meter accelerated walk test (4x10m)

    Baseline, immediately after intervention and follow up evaluations of 12 and 24 weeks.

  • Global rating of change - GRC scale

    Immediately after intervention and follow up of 12 and 24 weeks.

Other Outcomes (1)

  • Blinding and use of elastic bandage.

    Follow up 24 weeks

Study Arms (3)

Compression Group

EXPERIMENTAL

The volunteer must remain supine on a stretcher, with both legs extended and relaxed. The intervention will be performed with elastic bandages (Selecta® of 13cm x 160 cm, composed of 45% cotton, 20% elastodiene and 27% polyamide) involving the entire knee surface, positioned considering anatomical aspects: covering the femoral condyles and the anterior tibial tuberosity). The bandage will involve the knee from the distal to the proximal, respecting the blood flow of the venous return. The level of compression was defined according to recommendations in the literature on compression interventions in lymphedema and venous changes, and should be kept between 30 mmHg and 60 mmHg. Variations on stipulated values may be interfered according to the volunteer's self-report, which should indicate a level of moderate, comfortable and pain-free compression. The intervention will be carried out for 20 minutes, once a day, for 4 consecutive days.

Other: Elastic bandage compression

Sham Group

SHAM COMPARATOR

For Sham application, the volunteer must remain supine on a stretcher, with both lower limbs extended and relaxed. Elastic bandages will be used (Selecta® of 13cm x 160 cm, composed of 45% cotton, 20% elastodiene and 27% polyamide) involving the entire knee surface, positioned considering anatomical aspects: covering the femoral condyles and the anterior tibial tuberosity) . The bandage will involve the knee from the distal (tibial tuberosity) to the proximal (femoral condyles), respecting the blood flow of the venous return. However, in this group, no compression force will be performed, maintaining the pressure at 00 mmHg according to a previous reliability study. The procedure will be carried out for 20 minutes, once a day, for 4 consecutive days.

Other: Elastic bandage compression

Control Group

NO INTERVENTION

The Control group will be composed of individuals with knee osteoarthritis, who make up the study's waiting list and will carry out evaluations at the same time intervals as the other groups, but will not receive any type of intervention and will be instructed not to start another treatment during their participation.

Interventions

The compression will be applied with the volunteer in the supine position on a stretcher, with both lower limbs extended and relaxed. The intervention in the Compression group will be with elastic bandages involving the entire surface of the knee, positioned considering anatomical aspects: femoral condyles and the anterior tibial tuberosity. The level of compression must be maintained between 30 mmHg and 60 mmHg, according to the researched literature. The variations within these values will be stipulated according to the volunteer's self-report (comfortable and painless compression). The Shan Group will have the bandage wrapped around the knee without any compression force being exerted. The intervention will be carried out for 20 minutes, once a day, for 4 consecutive days. The Control group will be composed of volunteers who make up a study waiting list and will carry out the evaluations at the same time intervals as the other groups, but will not receive any type of intervention.
