Study hypothesis
The principle objective is to discover if there is any increase in brain activity when subjects perform a simple proprioceptive test with and without a piece of tape across the knee cap.

Condition
Musculoskeletal Diseases: Knee
Intervention
The subjects will lie in the scanner wearing shorts. A plastic block will support the thigh and knee at an angle of 45 degrees of knee inflexion. A strap will be placed over the hips to further limit head motion as a consequence of lower limb motion. Every effort will be made to control head movement by using a foam pad velcro strap and a bite bar. To ensure minimum ankle, foot and toe movements during the test, these joints will be placed in a neutral position and held by a temporary plaster cast and velcro straps.
MR scanning using the BOLD technique will be performed using a 1.5 tesla machine. The scanning protocol will be based on a functional time series. Each time series will consist of 4 blocks of 4 conditions: knee joint extension to 0deg, extension to 20deg with or without patellar tape. Each condition will last 5 minutes consisting of 30 sec on (ie the task) and 30 sec off (no task) and will be triggered by an auditory command given by using headphones customised for fMRI experiments. A metronome will pace the movements using sound in order to impose a constant timing and equal no of cycles across conditions.
Patellar taping will then be applied. The order of tape/no tape will be randomised
The acquired images will be assessed carefully for head movement and in order to correct the confounding effects induced by head movement realignment parameters. To process the data, statistical parametric mapping will be used to display the significance of activation and to analyse functional and anatomical image. SPM is the most prevalent approach to characterising activity related changes (Friston et al 2000).

Eligibility
Participant inclusion criteria
8 healthy volunteers between the ages of 20-40 years will have refrained from any physical exercise for 3 days prior to the testing. They will sign a consent form after reading the study information sheet and after having had the opportunity to ask questions about any aspect of the study and their role.
There is no control group. All subjects will act as their own internal controls.
