Changes in Grip Strength by Using Bandage Kinesio Taping

Study Overview
=================
Brief Summary
-----------------
The Kinesio Taping® method, therapeutic bandage, is another feature can be used in physical therapy, aiming to muscle enhancement, weakened muscles correction, analgesia, among others, by cutaneous stimulation of mechanoreceptors. This study aims to evaluate the efficiency of the use and effects offered by Kinesio Taping® method, changes in muscle strength of grip in normal subjects for clinical application.

Detailed Description
-----------------
A sample of 45 subjects will be divided randomly into three groups (G1: muscle activation technique; G2: muscle inhibition technique; G3: Placebo Effect) aged over 18 years male or female, where it will be initially measured the strength of grip with a dynamometer Jamar® pressure. Then the Kinesio Taping® bandage will be applied in an I format in the wrist flexor muscles of a dominant and non-dominant limb in G1, G2, and G3 groups. Investigators will follow the application protocol suggested by method of technical. To provide the facilitation of muscle activity (G1 group) a Kinesio Taping® bandage will be applied to the muscle starting at its origin up to the location of muscle insertion. For inhibition of muscle activity (G2 group), the bandage will be placed over the muscle starting at the insertion location and ending at the muscle origin. For the control group (G3 group) the bandage will be placed from the lateral extremity to the medial axis. The measurement of grip strength was carried out in four stages: immediately before placing the Kinesio Taping®, 24 h, 48 h, and 72 h after its application. After collecting the data statistical Investigators will held the analysis of the data.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Kinesio Taping for facilitation<br>To provide the facilitation of muscle activity (G1 group) a Kinesio Taping® bandage will be applied to the muscle starting at its origin up to the location of muscle insertion. Bandage in group G1 will be applied following the protocol proposed by method of technical, which defined the direction of the bandage and an applied tension of 10% to 15% (paper off). With a dynamometer Jamar® pressure the grip strength will be messure in four stages: immediately before placing the Kinesio Taping®, 24 h, 48 h, and 72 h after its application. | Other: Kinesio Taping® bandage<br>* The Kinesio Taping® bandage will be applied in an I format in the wrist flexor muscles of a dominant and non-dominant limb in G1 and G2 groups.<br>Other: Dynamometer Jamar® pressure<br>* The Jamar® dynamometer will be adjusted to the second position for measurement of maximal voluntary strength of handgrip. A muscle contraction period of three seconds will be performed in order to record handgrip strength.<br>|
| Experimental: Kinesio Taping for inhibition<br>For inhibition of muscle activity (G2 group), the Kinesio Taping® bandage will be placed over the muscle starting at the insertion location and ending at the muscle origin. Bandage in group G2 will be applied following the protocol proposed by method of technical, which defined the direction of the bandage and an applied tension of 10% to 15% (paper off). With a dynamometer Jamar® pressure the grip strength will be messure in four stages: immediately before placing the Kinesio Taping®, 24 h, 48 h, and 72 h after its application. | Other: Kinesio Taping® bandage<br>* The Kinesio Taping® bandage will be applied in an I format in the wrist flexor muscles of a dominant and non-dominant limb in G1 and G2 groups.<br>Other: Dynamometer Jamar® pressure<br>* The Jamar® dynamometer will be adjusted to the second position for measurement of maximal voluntary strength of handgrip. A muscle contraction period of three seconds will be performed in order to record handgrip strength.<br>|
| Placebo Comparator: Kinesio Taping and Placebo<br>For the control group (G3 group) the Kinesio Taping® bandage will be placed from the lateral extremity to the medial axis. Bandages in the G3 group will be applied laterally to produce a similar visual effect, which control for the placebo effect, but without tension so that a muscle stimulus will be not generated. With a dynamometer Jamar® pressure the grip strength will be messure in four stages: immediately before placing the Kinesio Taping®, 24 h, 48 h, and 72 h after its application. | Other: Dynamometer Jamar® pressure<br>* The Jamar® dynamometer will be adjusted to the second position for measurement of maximal voluntary strength of handgrip. A muscle contraction period of three seconds will be performed in order to record handgrip strength.<br>Other: Placebo<br>* For the control group (G3) the Kinesio Taping® bandage will be placed from the lateral extremity to the medial axis.<br>|

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change handgrip strength at 72 hours | At each stage (24, 48 and 72 hours) the volunteer must perform the measurement of strength three times respecting a period of rest between measurements than a minute. | 24, 48 and 72 hours |
