The Effect on Knee Joint Loads of Analgesic Use Compared With Exercise in Patients With Knee Osteoarthritis - An RCT (EXERPHARMA)
The Effect on Knee Joint Loads of Instruction in Analgesic Use Compared With NEUROMUSCULAR Exercise in Patients With Knee Osteoarthritis - A Single Blind RCT
The purpose of this study is to compare the effects of neuromuscular exercise and analgesic use on knee joint load, in patients with mild to moderate knee osteoarthritis (OA).
It is expected that the two groups will receive equipotent pain relieving effect, despite this, the investigators expect a between group difference in knee joint load, and the exercise group will have a reduction in knee joint load.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: NEMEX
NEuroMuscular EXercise
|
The exercise group receives 1 hour of supervised neuromuscular exercise two times a week for 8 weeks.
Supervision is conducted by physiotherapists specially trained in using neuromuscular exercise and its principles.
Other Names:
|
Active Comparator: PHARMA
PHARMAcological pain relief
|
The PHARMA group receives instruction, by video and pamphlet, on how to best use acetaminophen and NSAID as pain management for knee OA.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change from baseline in 1st peak RMS (root mean square) Knee Index.
Time Frame: Baseline and post intervention (8 weeks)
|
1st peak RMS Knee Index, is combined of the moments of the 3 planes working over the the knee; flexion, adduction and internal rotation moments. Measured with the Vicon system. 1st peak RMS knee moment = √(Kflex. moment2 + Kadd. moment2 + Kint.rot. moment2 )/3 |
Baseline and post intervention (8 weeks)
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change from baseline in 1st peak Knee adduction moment
Time Frame: Baseline and post intervention (8 weeks)
|
Baseline and post intervention (8 weeks)
|
|
Change from baseline in the KOOS (Knee injury and Osteoarthritis Outcome Score) questionnaire
Time Frame: Baseline and post intervention (8 weeks)
|
Baseline and post intervention (8 weeks)
|
|
Change from baseline in Maximum number of one-leg rises from stool test
Time Frame: Baseline and post intervention (8 weeks)
|
This test evaluates maximal performance and muscle strength in the lower extremity
|
Baseline and post intervention (8 weeks)
|
Change from baseline in Maximum number of knee-bendings in 30s test
Time Frame: Baseline and post intervention (8 weeks)
|
This test evaluates the ability to perform fast changes between eccentric and concentric muscle force over the knee joint
|
Baseline and post intervention (8 weeks)
|
Change from baseline in One-leg hop for distance test
Time Frame: Baseline and post intervention (8 weeks)
|
The test mimics sporting activities and demands muscle explosivety, balance and functional stability of the knee
|
Baseline and post intervention (8 weeks)
