Comparison Between Supervised Group Exercise and Home Exercise Program for Knee Osteoarthritis
Condition: Osteoarthritis, Knee
MeSH terms: Osteoarthritis; Osteoarthritis, Knee
Study type: Interventional

Summary: 
      Physical exercise is a widely recommended treatment modality for osteoarthritis, which can be
      performed through a supervised group exercise or a home exercise program. However, up to now
      only little research has been conducted on the home exercise program in Brazil. The objective
      of this study is to compare the efficacy between supervised group exercise and home exercise
      program in people with knee osteoarthritis. Methods: The study population consists of 46 men
      and woman with knee osteoarthritis aged between 40 and 65. The patients should be clinically
      diagnosed with knee osteoarthritis and classified in Kelgreen-Laurence grades I, II and III.
      Primary outcomes are the Westerm Ontário and McMaster Universities (WOMAC), Lower Extremity
      Functional Scale (LEFS), Pain Catastrophizing Scale (PCS), Tampa Scale for Kinesiophobia,
      40-meter walk test, isometric strength of hip (abduction and adduction) and knee (flexion and
      extension) and postural control. The patients are randomized into 2 groups, with one group
      receiving 12 sessions of supervised group exercise and the other group following an exercise
      program at home. The program lasts 6 weeks with both groups receiving the same exercise
      protocol consisting of stretching, isometric and isotonic exercises for major muscle groups
      in both lower extremities. The Mann-Whitney U test is used to examine the Anthropometric
      variables. The ANOVA is used to compare outcomes before and after treatment. A value of p<
      0.05 is considered to be statistically signifcant.
