Study summary

The purpose of this study is to determine whether:

  1. Progressive resistance training improves pain and disability
  2. Progressive Resistance training improves muscular strength, ability to walk and quality of life
Read the detailed description

Patients in experimental group participated in a 12-week progressive resistance training using a repetition maximum (RM) exercise in which patients performed 1RM with the maximum bearable weight. Once the 1RM was determined, training was divided into the following regimen: 2 series of 8 repetitions, the first with 50% and the second with 70% of 1RM.

The exercises were knee extension and flexion and hip abduction and adduction, all performed in machines. The 1RM load was reevaluated every 2 weeks.

The control group remained on a three-month waiting list for physiotherapy. Patients were assessed for pain, function, quality of life, muscle strength and six-minute walk test.
