Brief Summary

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

People with osteoarthritis (OA) of the knee attending The Alfred hospital will be invited to participate in a randomised controlled trial comparing two different types of knee taping. Both groups will also be prescribed an exercise program to assist in management of their knee OA.

Hypothesis are as follows:

1. Participants treated with flexible tape with have greater reductions in pain and improvements on timed performance based measures when compared to those treated with a placebo tape.
2. Participants in both groups will have clinically significant improvements in pain and timed performance based measures compared to their baseline scores.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Interventions:

Participants in both groups will attend physiotherapy on 4 occasions, in addition to an initial appointment where baseline data will be collected.

All participants will be provided with an individualised home exercise program. This will be provided based on the investigators' clinical experience and evidence based programs. The participant will be provided with a handout detailing the exercises they are to complete, including dosage. If there is excessive pain or difficulty associated with completing an exercise the participant will be advised to cease that particular exercise until they have been reviewed by the researcher the following week.

Participants will have their knee taped according to either the therapeutic flexible taping protocol, or the placebo taping protocol depending on which group they have been randomly allocated to on three occasions at one week intervals. All participants will be provided with written information regarding tape allergies and when to remove the tape from their knee. To control for the Hawthorne effect participants will not be aware of whether they are in the intervention or placebo group.

Participants will attend for appointments once per week for three weeks. They will then have a three week period of no intervention and return for a review and completion of the study. At this time the participant can be referred for further physiotherapy intervention as is clinically indicated. This may include physiotherapy at The Alfred Hospital, private practice or the participants' local health services.

If at anytime a participant wishes to withdraw from the study they can be referred by the investigators to continue their physiotherapy in the appropriate setting.

Sample size calculations: The investigators hypothesise that the combination of taping and an exercise program will give rise to clinically significant improvements in functional capacity, symptoms and quality of life. If there is truly no difference in the change in VAS between placebo and therapeutic based groups, then 30 patients are required to be 90% sure that the 95% confidence interval will exclude a difference in means of more than 20mm. This has been demonstrated by Tubach and colleagues in 2005. This assumes a standard deviation of the change in VAS of 21.5. Due to participant attrition anticipated an additional 20% will be recruited to the sample. This will total 36 participants in total.

Feasibility: The osteoarthritis hip and knee clinic at The Alfred hospital review approximately 13 patients per week of which the majority would be appropriate for inclusion in this trial. There are also many referrals from orthopaedics, rheumatology and emergency for patients who will be appropriate for inclusion. It is therefore anticipated that recruitment to the study will not be a barrier to completion of this trial.

Statistical analysis: All data will be analysed by intention to treat. Continuous variables will be analysed using analysis of covariance, controlling for baseline values and recruitment centre. The proportion of participants who complete the program will be compared between groups using a chi-squared test and the relative risk of non-completion will be determined. Alpha will be set at 0.05

Sham tape

* Fixomull tape only
* Single piece of 10cm wide, 32cm long applied from inferior to tibial tuberosity, over patella and onto quadriceps muscle. Corners rounded. Tape to be applied with the knee in 90 degrees flexion.

Flexible tape

Flexible tape (rocktape brand) applied as follows:

First piece of tape 10 cm wide and 32cm long (length of a standard goniometer). Split down centre 18cm from 1 end. Second piece of tape 5cm wide and 14cm long.

Tape applied in 90 degrees knee flexion Applied with no tension in proximal and distal ends. 30% tension to un-split portion placed over quads. 50% tension to split portion placed either side of patella and crossing over at tibial tuberosity Additional piece of 5cm wide flexible tape applied with 80% tension over patella tendon, with no tension in 3cm from ends All tape corners rounded

Participants in both groups will also be prescribed an individualised home exercise program by a physiotherapist.
