Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a randomized controlled trial investigating the effect of variable load training in patients with knee osteoarthrosis.

The intervention will consist of resistance training with variable load in knee extension- and flexion. The control group will receive conventional strength training with rubber band.

Outcome measures will be the Knee Osteoarthrosis Outcome Score, functional capacity measured in a sit to stand test, 30m. pace walk and a 9 step stair climb test. Additionally isometric strength in knee flexion- and extension will be measured.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Variable load training

The participants will be training two times per week in 10 weeks. Training will consist of variable load training in knee flexion- and extension.

Training will be based on symptoms in isometric strength at five different angles of flexion- and extension.

Group Type EXPERIMENTAL

Variable load training

Intervention Type OTHER

Based on symptoms/strength measured in an isometric maximum strength test at five different angles of knee flexion- and extension, participants will be training with variable load during both concentric and excentric phase of the dynamic movement. Initially participants will start at 40% of symptom limited isometric strength, this will increase to 50% during the training period.

Conventional strength training

The participants will be training two times per week in 10 weeks. Training will consist of a training programme consisting of strength training with rubber bands for hip and knee.

Group Type ACTIVE_COMPARATOR

Conventional strength training

Intervention Type OTHER

Conventional strength training with rubber bands in knee flexion- and extension, additionally hip abduction- and adduction.
