Kinesio Taping, Knee Osteoarthritis
Conditions
Brief summary
Osteoarthritis (OA) of the knee is a disease characterized mainly by the wear and tear of the articular structures, which affects 6% to 13% of men and 7% to 19% of women, and their prevalence may be increased proportionally with increasing age. Signs and symptoms include pain, joint stiffness and loss of function. In this perspective, kinesio taping (KT) appears as an alternative therapeutic resource for the treatment of this type of patient. However, the current evidence on this technique is limited and conflicting, making its effects on the symptomatology of the disease still uncertain. Thus, the present study will evaluate the effects of KT application on muscle strength, pain, physical function, edema and quality of life of elderly women with knee OA. It will be a randomized, blind clinical trial in which 45 volunteers will be allocated to three groups: G1 (placebo group), G2 (control group) and G3 (intervention group). The G1 will be submitted to the placebo (no tension) application of KT on rectos femoris muscle and knee; the G2 will receive a protocol of a health education activity session lasting 60 minutes and finally the G3 will be submitted to the simultaneous application (with tension) of two KT techniques on rectos femoris muscle and knee. All groups will be evaluated before, immediately after and 72 hours after the application. To measure the variables, the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), Numerical Pain Rating Scale (NPRS), 6-minute walk test (6MWT), isometric dynamometer, perimetry and global rating of change. Statistical analysis will be done using SPSS® software (Statistical Package Social Science) version 20.0. The Kolmogorov-Smirnov and Levene tests will be applied to evaluate the normality and homogeneity of the data, respectively. Intra and intergroup comparisons will be evaluated using analysis of variance ANOVA of mixed model. In the presence of a significant F, the Benferroni pot-hoc test will be used to identify where the difference occurred. For all statistical analyzes, a significance level of 5% (p \<0.05) and 95% confidence interval (95% CI) will be adopted.

Intervention model description
The volunteers will be recruited from the waiting list of the Clinic School of Physiotherapy of the Faculty of Health Sciences of Rio Grande do Norte, as well as the community in general. Initially, a signature will be requested from the TCLE and the next series of personal data. When we are already included, how should participants assess pain, muscular strength, edema and physical function (T0). Then all of them must be allocated to one of the three groups, where due intervention is required for each group. After one session, muscle strength and pain were again assessed (T1) and 72 hours later (T2), all outcomes assessed at time T0 were retested, including the global rating of change.

Inclusion criteria
* • Female subjects aged 60 years and over, non-obese (BMI between 18.5 and 24.9 kg / m2), with diagnosis of knee OA according to the criteria of the American College of Rheumatology (Altman et al. , 1986), which are: knee pain most of the day during the last weeks and age greater than 60 years (mandatory criteria), and at least two of the following criteria: stiffness after rest less than 30 minutes, crackle in the affected knee , joint increase of firm consistency, absence of temperature increase and painful hypersensitivity to palpation; * Individuals with radiographic signs of degeneration of the knee joint; * Individuals with any degree of degeneration according to the Kellgren-Lawrence scale; * Individuals with a pain scale above 3 according to NPRS; * Stiffness in the knee for at least 6 months prior to screening; * Stiffness during the beginning of activities; * Intermittent swelling; * Never have used KT; * Individuals with no history of associated joint disease or systemic rheumatic disease and / or history of surgery in the affected lower limb; * Individuals who are not under physiotherapeutic treatment during the intervention; * Individuals without neurological, vestibular, visual or auditory deficits that make evaluations impossible.
Exclusion criteria
* • Individuals who report pain during the procedure; * Individuals who do not complete the treatment time or who do not perform the evaluation procedures correctly, making it impossible to collect any of the data investigated; * Individuals with allergy to bandage or cutaneous injury in the region where KT will be applied; * Individuals who present hypertensive peak during the evaluations.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Numerical Pain Rating Scale (NPRS) | Time 0 - baseline | The primary outcome will pain assessed by the NPRS, whereby participants were asked to choose a number between 0 (no pain) and 10 (worst pain possible). They will instructed to report the level of pain while sitting and rising from a chair. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Perimetry | Time 0 - baseline | To perform perimetry, a tape measure will be used to measure the perimeter of the assessed limb. For this, the volunteer will be placed in dorsal decubitus with hip in neutral position, extended knees and relaxed quadriceps. In this position, the evaluator will measure the knee at three specific points: the fold of the popliteal fossa, 5 cm above and 5 cm below. Each level will be evaluated three times and the average of the measurements will be used for analysis. |
| Quadriceps muscle strength | Time 0 - baseline | The isometric strength of the femoral quadriceps will evaluated using a hand-held dynamometer (HHD; Nicholas Manual Muscle Tester, Lafayette Instrument Company, Lafayette, Indiana, USA). The participant will placed in the sitting position on a stretcher, with arms crossed over chest. An ankle stabilization belt will placed on the evaluated limb to maintain hip and knee flexion at 90°. The HHD will placed 2 cm proximal to the lateral malleolus midpoint, in the anterior region of the ankle (between the malleoli). Maximum isometric strength will then measured in 5-second knee extensions, with continuous verbal encouragement. Subjects perform one practice trial, rested for 30 s and then carried out the three measured trials, the strongest of which will use for data analysis. The results of all trials \[kg\] will transformed into Newtons (Strength\[N\] = strength \[kg\] x 9.81) and normalized by body mass (Normalized Strength \[N/kg\] = Strength \[N\] ÷ Body Mass\[kg\]). |
| Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) | Time 0 - baseline | Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) is a reliable and validated instrument for the Portuguese language that contains 24 questions divided into three categories: pain (5 questions), rigidity (2 questions) and self-reported physical function (17 questions). The items are evaluated by a Likert scale and each question receives a score ranging from 0 to 96, according to the patient's response. The higher the score obtained, the worse is the severity of the disease (BELLAMY et al., 1988). |
| 6-minute walk (6MWT) | Time 0 - baseline | The six-minute walk test (6MWT) will follow the recommendations of the American Thoracic Society (2002). A distance of 30 meters will be demarcated by two cones (one in the initial mark and the other in the final mark). The volunteers will be instructed to walk the greatest number of times the distance marked for six minutes and, at the end of this time, the distance traveled will be measured, in this case, the greater the distance covered, the better the patient's function. |
| Global rating of change | Time 2 - after 72 hours of baseline | This will assessed via the patient global impression of change. The measure is recommended by the Initiative on Methods, Measurement, and Pain Assessment in Clinical Trials group and targets four different domains: pain, function, quality of life, and global condition, measured using a 7-point scale (from 'considerably improved' to 'considerably deteriorated'). |
