Brief Summary

The aim of the present study is to evaluate the effects of WB-EMS application in overweight women and men with knee osteoarthritis, with special consideration of sustainability. In this randomised controlled trial 72 overweight patients with knee osteoarthritis aged 40-70 years will be included and randomly assigned to two groups (WB-EMS vs. control group (CG)). The intervention group will perform six WB-EMS sessions/month of 20 min for 6 months. An intermittent low frequency WB-EMS-protocol with an impulse phase of 6s, followed by an impulse break of 4s will be applied. The control group will undergo a tailored physiotherapy program of 6 sessions defined as usual care. In addition, both groups will complete a self-management training programme for osteoarthritis of 6 sessions over 12 weeks.

Outcome Measures

Primary Outcomes (1)

  • Knee pain

    Changes in pain of the knee joint as determined by the Knee Injury and Osteoarthritis Outcome Score (KOOS) in the WB-EMS- compared to changes in the control group.KOOS score for "knee pain" vary from 1 (never/no pain) to 5 (always/very severe pain)

    baseline to 6 month follow up

Secondary Outcomes (18)

  • Self rated symptoms

    baseline to 6-month follow-up

  • Knee stiffness

Study Arms (2)

WB-EMS group

EXPERIMENTAL

WB-EMS application

Other: Whole-Body Electromyostimulation

Control

ACTIVE COMPARATOR

Standardised physiotherapy (six sessions)

Other: Physiotherapy

Interventions

Consistently supervised, video-guided WB-EMS application 1.5 times per week for 28 weeks. Bipolar electric current with a frequency of 85Hz, an impulse-width of 350 µs will be used in an interval approach with 6 sec of EMS stimulation with a direct impulse boost and 4 sec of rest. Low intensity movements or exercises in a standing position were performed during the 6 s stimulation period.

WB-EMS group

Six standardised physiotherapy sessions (20 min each)

Control
