          Abstract

          Abstract Introduction: Osteoarthritis is a disease that affects millions of Brazilians.Therapeutic ultrasound has been used in its treatment, either alone or associated with drugs. Objective: The aim of this study was to evaluate the effects of ultrasound (US) associated with Copaiba oil (CO) on knee osteoarthritis. Methods: Patients were divided into three different groups: US, US+CO, CO.Ten treatment sessions were held twice a week, 30 minutes each.Pain intensity was assessed through the Visual Analog Scale (VAS) and Range of Motion (ROM) by goniometry, and muscle strength was assessed by means of the Medical Research Council Scale. Statistical analysis was performed by Cohen’s d test, student’s t test and ANOVA, considering p<0.05 as significant. Results: Pain reduced in all groups.The US+CO group (d = -3.50) presented larger effect size when compared to the other groups. Regarding ROM, the largest effect size was observed in the US+CO group for flexion (d = 0.86) and extension (d = 0.97) in comparison with the remainder groups. Muscle strength increased in the US (d = 1.54) and US+CO (d = 1.60) groups for flexion.Regarding extension, the US group presented the largest effect size (d = 1.80). Conclusion: Therapeutic ultrasound associated with copaiba oil is a practical and effective therapy for the treatment of inflammatory diseases such as osteoarthritis.

          Resumo Introdução: A osteoartrite é uma doença que afeta milhões de brasileiros. O ultrassom terapêutico tem sido utilizado em seu tratamento tanto sozinho, quanto associado a fármacos. Objetivo: Avaliar o efeito do ultrassom (US) associado ao óleo de copaíba (OC) em pacientes com osteoartrite de joelho. Métodos: Os pacientes foram distribuídos em 3 grupos distintos: US, US+OC e OC. Foram realizadas 10 sessões de tratamento, duas vezes por semana durante 30 minutos. A intensidade da dor foi avaliada pela Escala Visual Analógica da Dor (EVA), amplitude de movimento ADM pela goniometria e força muscular pelo Score Medical Research Council. A análise estatística foi feita pelo Teste T de Student e ANOVA e a magnitude do efeito (d), considerando p<0,05 como valores significativos. Resultados: A dor foi atenuada em todos os grupos, sendo apresentada uma magnitude maior do efeito para o grupo US+OC (d = -3,50) quando comparado aos demais grupos. Em relação a ADM a magnitude do efeito foi maior no grupo US+OC (d= 0,86) para a flexão e extensão (d = 0,97) quando comparados com os outros grupos. Na variável força muscular os grupos US (d= 1,54) e US+OC (d = 1,60) foram mais eficazes no movimento de flexão e na extensão, o grupo US exibiu o maior tamanho de efeito (d = 1,80) quando comparados aos demais grupos. Conclusão: O ultrassom terapêutico associado ao óleo de copaíba é uma terapia efetiva e prática para o tratamento de doenças inflamatórias, tais como a osteoartrite.

          Reduced quadriceps strength relative to body weight: a risk factor for knee osteoarthritis in women?

          To determine whether baseline lower extremity muscle weakness is a risk factor for incident radiographic osteoarthritis (OA) of the knee. This prospective study involved 342 elderly community-dwelling subjects (178 women, 164 men) from central Indiana, for whom baseline and followup (mean interval 31.3 months) knee radiographs were available. Lower extremity muscle strength was measured by isokinetic dynamometry and lean tissue (i.e., muscle) mass in the lower extremities by dual x-ray absorptiometry. Knee OA was associated with an increase in body weight in women (P = 0.0014), but not in men. In both sexes, lower extremity muscle mass exhibited a strong positive correlation with body weight. In women, after adjustment for body weight, knee extensor strength was 18% lower at baseline among subjects who developed incident knee OA than among the controls (P = 0.053), whereas after adjustment for lower extremity muscle mass, knee extensor strength was 15% lower than in the controls (P not significant). In men, in contrast, adjusted knee extensor strength at baseline was comparable to that in the controls. Among the 13 women who developed incident OA, there was a strong, highly significant negative correlation between body weight and extensor strength (r = -0.740, P = 0.003), that is, the more obese the subject, the greater the reduction of quadriceps strength. In contrast, among the 14 men who developed incident OA, a modest positive correlation existed between weight and quadriceps strength (r = 0.455, P = 0.058). No correlation between knee flexor (hamstring) strength and knee OA was seen in either sex. Reduced quadriceps strength relative to body weight may be a risk factor for knee OA in women.

            Reliability and validity of goniometric measurements at the knee.

            The purposes of this study were to assess the intertester reliability of goniometric measurements at the knee and the validity of the clinical measurements by comparing them to measurements taken from roentgenograms. Thirty healthy subjects between the ages of 20 and 60 years were studied. The subjects were positioned on their right side on a roentgenographic table with their left lower extremity on a stabilizing board that was elevated 15 cm above the table's surface. For standardization of the position, an assistant placed the posterior aspect of the subject's left thigh in contact with two 15-cm pegs, which had been inserted perpendicularly into the stabilizing board. The assistant then moved the left leg to achieve an arbitrary angle of the knee joint and held the limb in that position. Two physical therapists then independently used a standard plastic goniometer to measure the knee joint angle in the sagittal plane using the greater trochanter, the lateral condyle of the femur, the head of the fibula, and the lateral malleolus as bony landmarks. A roentgenogram was taken of the extremity before the subject was moved. Pearson product-moment correlation coefficients (r's) and intraclass correlation coefficients (ICCs) were used to analyze the data. The data analysis revealed that the intertester reliability (r = .98; ICC = .99) and validity (r = .97-.98; ICC = .98-.99) were high. The results of this study indicate that goniometric measurements of the knee joint are both reliable and valid.

              A review of therapeutic ultrasound: effectiveness studies.

              Therapeutic ultrasound is one of the most widely and frequently used electrophysical agents. Despite over 60 years of clinical use, the effectiveness of ultrasound for treating people with pain, musculoskeletal injuries, and soft tissue lesions remains questionable. This article presents a systematic review of randomized controlled trials (RCTs) in which ultrasound was used to treat people with those conditions. Each trial was designed to investigate the contributions of active and placebo ultrasound to the patient outcomes measured. Depending on the condition, ultrasound (active and placebo) was used alone or in conjunction with other interventions in a manner designed to identify its contribution and distinguish it from those of other interventions. Thirty-five English-language RCTs were published between 1975 and 1999. Each RCT identified was scrutinized for patient outcomes and methodological adequacy. Ten of the 35 RCTs were judged to have acceptable methods using criteria based on those developed by Sackett et al. Of these RCTs, the results of 2 trials suggest that therapeutic ultrasound is more effective in treating some clinical problems (carpal tunnel syndrome and calcific tendinitis of the shoulder) than placebo ultrasound, and the results of 8 trials suggest that it is not. There was little evidence that active therapeutic ultrasound is more effective than placebo ultrasound for treating people with pain or a range of musculoskeletal injuries or for promoting soft tissue healing. The few studies deemed to have adequate methods examined a wide range of patient problems. The dosages used in these studies varied considerably, often for no discernable reason.
