Investigation of the Effect of Epicondylitis Band and Wrist Orthosis

Study Overview
=================
Brief Summary
-----------------
Muscles that are frequently injured in the extensor group are extensor carpi radialis longus, extensor carpi radialis brevis, and extensor digitorum communis. Injury of these muscles is seen as lateral epicondylitis in the clinic. Physiotherapy techniques are frequently applied in the management of diseases related to forearm extensor muscles such as lateral epicondylitis. Various orthoses such as lateral epicondylitis band, wrist orthosis, dynamic extensor brace are used for this. Studies have been conducted on pain, hand function and orthosis satisfaction of different types of lateral epicondylitis orthoses, and the number of studies investigating the effects on muscle activation is insufficient.Therefore, the aim of the study is to examine the effects of different types of orthoses used for the forearm extensor group on extensor muscle activation and upper limb functions.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Control group<br>The group measured without the use of orthoses and tapes | |
| Epicondylitis Band Group<br>Group measured with epicondylitis band | Other: epicondylitis band<br>* An off-the-shelf lateral epicondylitis tape in S-M-L dimensions was used distal to the lateral epicondylitis.<br>|
| Wrist Orthosis Group<br>Group measured with wrist orthosis | Other: wrist orhosis<br>* Wrist orthosis of the shelf was used in sizes S-M-L, covering the hand and wrist.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| muscle activation | A superficial EMG system will be used to measure signals from the extensor carpi radialis longus/brevis and extensor carpi digitorum communis muscles.Electrodes will be placed according to SENIAM criteria.The signals received from the muscles of the individuals will be recorded during grasping. As a result, the average muscle activations of the muscles during the activity will be numerically recorded in %MVIC. | one hour | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| hand function | Jebson Taylor Hand Function Test, which includes daily life activities (writing, eating, etc.) and consists of 7 sub-parameters, was applied to measure hand function. The score is recorded in seconds and the score gets worse as the second increases. | one hour | 
| satisfaction level | The OPUS questionnaire was used to measure the participants' orthotic satisfaction. The OPUS questionnaire evaluates the weight, durability, aesthetics, ease of putting on, skin and clothing problems, comfort, and the pain-reducing effect of the orthosis associated with the orthosis. The higher the score, the higher the level of satisfaction. | one hour |
