Brief summary
In this study the investigators want to measure the impact or effects of adding cryostimulation to the conservative care of chronic lateral epicondylitis. The rapid fall in skin temperature above the injured tissues is presume to have a positive effect in the healing process. The combination of conservative care and cryostimulation could then be appreciated. The investigators chose to measure these effects with 3 elements: visual analog pain scale, validated elbow questionnaire and pain free grip strength. This pilot study consist in a two arm design, each arm including 15 patients.
Detailed description
Lateral epicondylitis is one of the most prevalent upper limb conditions that can affect up to 1-3% of the active population. Invalidity and health care costs incurred by this condition are posing a real challenge to our societies knowing that the natural history of the lateral epicondylitis can last from 1 to 2 years. Many therapies have been tested and so far none has proven conclusive when used alone so far (Blanchette and Normand 2011). The use of cryostimulation is widespread in the sport scene without strong literature supporting its evidence. The aim of this study is to quantify the effects of cryostimulation when added to conservative care in the treatment of chronic lateral epicondylitis. Thirty (30) patients will be divided randomly in two groups: * The control group (n=15) will receive conservative care including myofascial trigger points (involved forearm) and radial head mobilisations (Bergmann & Peterson, 2010). * The experimental group (n=15) will receive the cryostimulation and the conservative treatment as mentioned above. A total of eight treatments will be given to each patient; the whole protocol lasting four to six weeks. The treatments will be delivered by experienced and trained clinicians in cryostimulation and myofascial treatment protocols. The effects of the two treatment protocols will be monitored by a validated elbow questionnaire (PRTEE, (Rompe, Overend et al. 2007)), a visual analog pain scale and the pain free grip strength at three moments: at inclusion, at the ninth visit and 3 months after the last treatment.
Interventions
DEVICEcryostimulation
pressurized cold air (-70 celsius degree) is blown on the skin surface surrounding the lateral epicondyle, creating a rapid decrease in ski temperature. In a 30-40 sec exposition, skin temperature can drop to 4 celsius degree. this rapid decrease is presumed to have a positive healing effect.
OTHERconservative care
manual treatment of localized tender and painful myofascial areas in the muscles surrounding the forearm and mobilization of the radial head.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Visual Analog Pain Scale | at inclusion - ninth visit - 3 months after last treatment | Subjects will be asked to rate their average pain for the last 24 hours on a scale ranging from 0 to 10 |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| pain free grip strength | at inclusion - ninth visit - 3 months after last treatment | we will use a hand-held dynamometer to mesure the painfree grip strength of the subjets. Subjects will be asked to gradually increase the grip stregth while the elbow is extented and arm along side of the body. They will be asked to stop when pain is felt. We will take three mesures with each elbow, left and right. |
Other
| Measure | Time frame | Description |
|---|---|---|
| Patient Rated Tennis Elbow | at inclusion - ninth visit - 3 months after last treatment | The questionnaire will be filled in by patients at the beginning of the three evaluations: inclusion, ninth visit and 3 months after last treatment |
