The Effectiveness of Dynamic Taping in Preventing Muscle Fatigue

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to assess the efficacy of dynamic tape in prevent shoulder muscle fatigue.

Detailed Description
-----------------
After being informed about the study and the potential of risk, all participants will undergo a screening to determine eligibility for study entry and giving written informed consent. We will include 20 participants who have pitch 100 times with dynamic taping or shame taping in randomized sequence. There must be more than 2 weeks resting between 2 test. We will test maximal force in shoulder flexion, extension, abduction and adduction before and after test. We also record spins and speed of baseball for performance outcome. To our hypothesis, we suggest dynamic taping could decrease the arm fatigue after long-term pitching.

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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change from baseline in shoulder force after pitching | The dynamometer is a validated instrument assessing shoulder and arm force which is recorded in kilogram | baseline and 2 weeks | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change of pitching velocity during pitching | The speed dun is a validated instrument assessing pitching velocity which is recorded in kilometer per hour | baseline and 2 weeks | 
| Change of pitching spin rate during pitching | The STRIKE baseball is a new instrument assessing pitching spin rate and axis which is recorded in rate per minute | baseline and 2 weeks | 
| Change of delayed onset muscle soreness after pitching | Visual analog scale is a validated self-record measure to assess delayed onset muscle soreness, which score range is 0 to 10. | baseline, 1 Day, 2 days, 3 days, 4 days, 5 days, 6 days, 7 days, 14 days |
