Direct effect of short wave diathermy therapy and exercise with quadriceps bench against knee osteoarthritis patients with functional capabilities

Osteoarthritis (OA) is a disorder of joint cartilage characterized by changes in the clinical, histological and radiological. OA knee associated with various pathological deficits such as pain, decreased range of motion of the knee joint and the quadriceps muscle nirguna atrophy. This study was observational analytic and design research using cross-sectional design. Subjects in this study were 30 patients with osteoarthritis of the knee in outpatient IRM Hospital Dr. Soetomo aged 40-70 years were taken with consecutive sampling technique the period from March to April 2015, an assessment of functional ability before and after treatment using a scale jette. The data in normal distribution and statistical test was then performed using paired t-test. Jette scale mean pre- and post-treatment with Short Wave Diathermy (SWD) modalities and exercises with Quadriceps Bench (QB) in patients with knee osteoartriitis show was different, with a value of less significance (p <0.05). This can occured because, blood flow in the tissues increase, throw away the metabolite residual, and decrease muscle spasms, so the pain is reduced and the functional ability of the knee increases.
