The Effect of Kinesio Taping on Wrist Flexor Sensorimotor Control in Healthy People

Study Overview
=================
Brief Summary
-----------------
This study explores the sensorimotor control effect of kinesio tape and confirms additional tension can influence the effect of kinesio tape. Kinesio tape will be taped on wrist flexor. There are three types of taping, one is taped with additional 20% tension, another is taped with neutral tension, the other is without taping. All participants will receive all types of taping. Our hypothesis is taping will improve wrist sensorimotor control and 20% additional tension will improve more than neutral tension.

Detailed Description
-----------------
Wrist and hand function is important in our daily life. People can do movement with proper force output and joint position sense due to sensorimotor control. In addition, people with better sensorimotor control have lower risk of injury. According to some researches, the investigators can improve wrist sensorimotor control with kinesio taping. However, there is no study comparing whether kinesio taping with additional tension improve sensorimotor control more than kinesio taping with neutral tension. In addition, many wrist movements in life are related to grip and the dominant muscle of grasping is wrist flexor. No research explores whether improving wrist sensorimotor control with kinesio taping on wrist flexor. Therefore, the investigators want to explore the effect of kinesio taping on wrist flexor sensorimotor control in healthy people.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| No Intervention: Control<br>Without kinesio tape on the forearm of subjects | |
| Placebo Comparator: kinesio taping with neutral tension<br>Kinesio tape with neutral tension on the forearm of subjects | Device: kinesio tape<br>* Kinesio taping(kinesio taping;kinesio holding corporation,USA) is given between the pretest and the posttest. The taping is operated by a physical therapist who is the co-host of this experiment in 614 room, Research Building, National Yang-Ming University. Posttest will be started immediately after taping. After posttest, kinesio tape will be removed. There are 3 types of taping conditions. Kinesio tape is pulled from 5 cm distal wrist joint line to medial epicondyle and 5 cm at both ends of the head and tail without tension .All participants will receive all conditions of taping. They will be randomly assigned to any taping conditions. In order to wash out the effect of taping, the interval of any condition is at least 7 days.<br>|

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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Joint position sense | The sense of wrist flexion 15 degree will be measured with Angle measurer (SS20L/21L, BioPAC Systems Inc., Santa Barbara, CA, USA) | It is a measure assessing change between two time points. (change between baseline and after taping 5 minutes) | 
| Force sense | 20% maximal voluntary contraction will be measuresd with dynamometer (G200; Biometrics Ltd, Cwmfelinfach, Gwent, UK) | It is a measure assessing change between two time points. (change between baseline and after taping 5 minutes) | 
| Reaction time | Grip reaction time will be measured with EMG system(Power1401 MK II,Grass,USA) | It is a measure assessing change between two time points. (change between baseline and after taping 10 minutes) | 
| Corticomuscular coherence | Participants maintain 20% maximal voluntary contraction for 30 seconds.corticomuscular coherence (beta band) will be measured with EEG system (actiCAP; Brain products GmbH, Germany) | It is a measure assessing change between two time points. (change between baseline and after taping 10 minutes) |
