The Efficacy of Exercise and Alternative Applications of NMES on Pain and Function in Patients With Knee OA
Condition: Knee Osteoarthritis
MeSH terms: Osteoarthritis; Osteoarthritis, Knee
Study type: Interventional

Summary: 
      The aim of the study was to investigate the efficacy of exercise and different size
      electrodes of neuromuscular electrical stimulation (NMES) applications on pain, range of
      motion (ROM), muscle strength, function status and depression in knee osteoarthritis.

      60 voluntary patients were included in the study and these patients divided into three groups
      randomly. For Group 1 only exercise, for Group 2 simultaneously active contraction with NMES
      with standard size electrodes, for Group 3 simultaneously active contraction with NMES with
      large electrodes applied for 3 days per week, 18 session. Pain was measured with Visual
      analog Scale (VAS), ROM was measured with digital goniometer, muscle strength was measured
      with "Hand-held" dynamometer (Lafayette Instrument®, Lafayette, IN), functional status were
      measured with WOMAC (Western Ontario and McMaster Universities) Index and stair climbing
      test, balance was analysed with one leg standing test, depression was scored with Hospital
      Anxiety Depression Scale and patients satisfaction was scored with Global Rating Change
      Scales. The cases evaluated before and after treatment.
    

Detailed description: 
      Aim: This study investigated the effect of neuromuscular electrical stimulation (NMES) was
      applied with different size electrodes on the functionality, pain, range of motion (ROM), and
      muscle strength in patients wtih knee osteoarthritis (OA).

      Material and Metod: Sixty patients with knee OA who received physical therapy for knee pain
      and functional disability at Istanbul University, Faculty of Health Sciences, Division of
      Physiotherapy were included. These patients divided into three groups randomly. Group 1
      applied exercise programme. Group 2 performed exercise programme with NMES with standard size
      electrodes (5×5 cm²). Group 3 performed exercise programme with NMES with large size
      electrodes (10×20 cm², 3×18 cm², 10 3×7.5 cm², 7×14 cm²) NMES was applied for 20 minutes to
      Group 2 and Group 3. The patients attended 18 treatment sessions 3 times per week in the
      physical therapy clinic and underwent assesment before treatment and after 6 weeks of
      treatment. Pain was measured with Visual Analog Scale (VAS), range of motion (ROM) was
      measured with digital goniometer, muscle strength was measured with ''Hand-held''
      dynomometer, functional status were measured with WOMAC (Western Ontario and McMaster
      Universities) Index and stair climbing test, balance was analysed with one leg standing test.
      Patients satisfaction was scored with Global Change Scales.
