BackgroundAlthough recent advances in knee osteoarthritis OA treatment and evaluation were achieved, to the best of our knowledge, few studies have evaluated the longitudinal effect of therapeutic modalities on the functional exercise capacity of patients with knee OA. The purpose was to investigate the effects of kinesiotherapy and electrotherapy on functional exercise capacity, evaluated using the six-minute walk test 6-MWT in patients with bilateral knee OA. Secondary measurements included range of motion ROM, severity of knee pain VAS, and a measure of perceived health and physical function, evaluated using the Western Ontario and McMaster Universities WOMAC Osteoarthritis Index.

MethodsA total of 40 women with bilateral knee OA were assigned to three groups: kinesiotherapy KIN, n = 16, transcutaneous electrical nerve stimulation TENS, n = 12, or ultrasound US, n = 10. The groups underwent 12 weeks of intervention twice per week. The participants were subjected to the 6-MWT, ROM, VAS and WOMAC index. These tests were performed before and after the intervention. The study was focused on outpatients and was carried out at Universidade Estadual de Campinas, Brazil.

ResultsAt follow-up, the KIN and US groups had significantly higher 6-MWT distances 19.8 ± 21.7 and 14.1 ± 22.5%, respectively compared with their respective pre-intervention values. All treatments were effective for reducing pain and improving the WOMAC index.

ConclusionsWe demonstrated that the 6-MWT is a tool that can be used to evaluate improvements in the functional exercise capacity of patients submitted to a clinical intervention.
