“…The Brazilian Portuguese version has three domains: pain (items 1, 2, 3, 4, and 5), stiffness (items 6 and 7), and physical function (items 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, and 24). However, Ferreira et al 17 found that the Brazilian version of the WOMAC with two domains (pain, 4 items; physical function, 8 items) presents a more adequate structure. For each item, there are options of five responses (0–4); the score for each domain is calculated as the simple sum of the answered items: pain domain (0–20), stiffness (0–8), and physical function (0–68); the higher the score, the greater the impact of osteoarthritis on the domains.…”

Osteoarthritis is a chronic degenerative disease that affects the joints, in particular, the knee is the most commonly affected. Pain, stiffness, and crepitus in joint movement are some of the symptoms that disable individuals. The treatment of this disease includes control of body mass (weight reduction), use of anti-inflammatory drugs, and exercise 1 .Recent studies have focused on understanding the risks of comorbidities associated with knee osteoarthritis 2 , the biochemical and gait parameters after arthroplasty 2,3 , and prognosis after therapies in bilateral knee osteoarthritis (B-KO) and unilateral knee osteoarthritis (U-KO) 4 .Asymmetry between the lower limbs seems to be more prevalent in individuals with B-KO 5 , while the reduction in muscle strength and volume of the affected limb is more observed in individuals with U-KO 6 , and both (B-KO and U-KO) have already been associated with primary and secondary hyperalgesia 7 . However, these clinical differences have been less investigated.Marmon et al. 8 and Messier et al. 9 described that, regardless of the number of affected knees, individuals with knee osteoarthritis have similar functional capacity and biomechanical parameters. Riddle and Stratford 10 pointed out that people with U-KO have higher levels of pain; however, according to the authors themselves, the differences between the clinical variables of bilateral and unilateral involvement in knee osteoarthritis remain controversial and little known. In this perspective, this study aimed to compare pain intensity, stiffness, functionality, central sensitization, and self-efficacy between individuals

“…WOMAC can be completed in a short time, and its reliability and sensitivity have been proven in different languages, with a scale test-retest reliability of 0.83 and a validity of 0.77. (31)(32)(33) As it is a selfadministered measurement, the participants will complete the measurements themselves. The study personnel will not be allowed to assist the participant to answer any of the questions; however, they will be required to check that all the questions have been completed before the patients complete all the assessments.…”

Background Osteoarthritis (OA) is the most prevalent joint disorder among musculoskeletal conditions. Non-surgical treatment is the conventional therapy for knee OA (KOA). Given the simplicity, feasibility, and effectiveness of physical therapy, it has become a widely used treatment. Ultrasound therapy is recommended for the treatment of pain and dysfunction caused by OA. However, a lack of scientific evidence of high-quality ultrasound treatment of OA still remains. Therefore, we want to analyze whether a combined treatment regimen using low-intensity pulsed ultrasound (LIPUS) can enhance the efficacy of conventional therapy, thus improving symptoms in patients with KOA. Methods This randomized controlled trial aims to recruit 34 patients diagnosed with knee osteoarthritis that meet the Altman clinical diagnostic criteria for KOA and are aged ≥ 38 years. The patients will be randomized in a 1:1 ratio into two groups: a low-intensity pulsed ultrasound treatment group and a sham ultrasound treatment control group. The treatment will last for 2 weeks, with five sessions per week. Study endpoints will be evaluated at baseline, on the day of the last intervention, and one month after the intervention. The main outcome measures will be the Western Ontario and McMaster Universities’ scores. Secondary outcome indicators will be the numerical pain rating scale, the Lequesne scale, the time up and go test, and the range of motion (ROM) of the knee. An intention-to-treat analysis will be performed for dropouts and missing data. Discussion By analyzing patients with OA that undergo or not ultrasound intervention, we will determine whether LIPUS can serve as an adjuvant treatment to enhance the efficacy of physical therapy. If ultrasound treatment plays a synergistic role with physical therapy in ameliorating symptoms in patients with knee OA, it may serve as a low-cost intervention to retard structural progression and alleviate KOA symptoms. Trial registration: The trial was registered on the Chinese Clinical Trial Registry platform (chictr.org.cn) on 03/22/2023, with the registration ID ChiCTR2300069643.

“…However, this study comes from a master's thesis and has not gone through a peer review process for publication in any scientific journal. Understanding this scenario, the rationale for testing the properties of the Brazilian Portuguese SV-WOMAC knee came from the results of Ferreira et al [12], who carried out the structural validity. And unlike the original version, with 24 items and 3 domains, it was reported that the best version of the WOMAC Knee with 2 domains and 12 items [12].…”

After these results, it became necessary to carry out this study so that it would be possible to verify, through adequate and solid clinometric bases, whether this questionnaire provides reliable data on the pain and physical function of individuals with knee osteoarthritis.…”

Background Assessment instruments play an essential role in the management of knee osteoarthritis. This study aimed to verify the clinimetric properties and validate the short version of WOMAC’s (SV-WOMAC) knee with two domains, pain (four items) and physical function (eight items) in individuals with knee osteoarthritis (KO). Methods Reliability and internal consistency Construct, criterion validity, Ceiling, and floor effects analyses were performed. In addition to the SV-WOMAC, the following instruments were used: the numerical rating scale (NRPS), International Knee Documentation Committee (IKDC), the Short Form Health Survey (SF-36), and WOMAC’s original version. Spearman’s correlation coefficient (rho) was used to determine the magnitude of the correlation between the AFAQ and the other instruments. Moreover, the test–retest reliability and internal consistency were assessed using the intraclass correlation coefficient (ICC) and Cronbach’s alpha, respectively. In addition, standard error of measurement (SEM) and minimum detectable change (MDC) were calculated. Results One hundred and thirteen subjects with KO were included for validity analysis, and a subsample of 53 subjects was used for test-retest reliability. Adequate reliability and internal consistency were observed with ICC ≥ 0.76, SEM ≤ 1.85, MDC ≥ 5.1, and Cronbach’s alpha ≥ 0.84. Regarding construct validity, correlations greater than 0.50 were observed with the IKDC, NRPS, and functional domains of the SF-36. The SV-WOMAC showed a correlation > 0.70 with the original version and did not show ceiling and floor effects. Conclusion The SV-WOMAC knee has adequate measurement properties to analyze pain and physical function in Brazilian individuals with KO.
