Study type
Interventional
Description of intervention(s) / exposure
A two group double-blind, randomised, placebo-controlled, repeated measures trial will be conducted to investigate the effectiveness of pulsed electrical stimulation (PES) in the management of people with osteoarthritis of the knee over a 26 week period. Subjects in both the intervention and placebo groups will be asked to use the transcutaneously applied PES and placebo-PES respectively at sub-sensory levels for a minimum of seven hours per day (overnight recommended) during the study period. All subjects will be able to continue their usual arthritis management throughout the trial period.

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Initial phone screening followed by final screening to ensure study criteria are met. Written informed consent gained, Stratification details sent to a person independent of the study for group allocation using computer software. Equipment allocated to subjects by serial number to maintain blinding of groups to all investigators.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Stratified randomisation (age, gender and initial pain score). Permuted block allocation.
Masking / blinding
Blinded (masking used)
