Clinical Trial Summary

The purpose of this experiment is to evaluate whether MyotonPRO can quantify the changes in the muscle characteristics of the erector spinae in different postures and after myofascial relaxation, and to test the validity of the muscle tone tester.

Description:

In clinical practice, manual muscle testing (MMT) and Modified Ashworth scale (MAS) grading systems are often used to assess muscle tension and tension. Although these methods are considered feasible, because these methods are mainly classified based on the subjective perception of the evaluator, the reliability and accuracy of the evaluation results are often questioned. Therefore, we should seek a way to objectively evaluate muscle tension with biomechanical properties and quantitative data to solve these deviations. MyotonPRO (Myoton AS, Tallinn, Estonia) is a tester that uses biomechanical principles to collect muscle tension status. This handheld muscle tension tester uses mechanical pressure and reaction force feedback to calculate through biomechanical conversion. The tone, stiffness and elasticity of the muscle are expressed as quantitative data. There have been many use reports showing that the muscle tone meter has the feasibility of quantifying muscle tone.

The erector spinae is one of the most important back muscles of the human body. After contraction, the entire spine can be erected, allowing the upper body to stand upright. When the posture changes, such as: sitting posture, hunchback, bending over, erector spinae will be stretched or continuously contracted due to different postures, resulting in changes in muscle characteristics. Therefore, if the erector spinae is used improperly for long-term poor posture, the erector spinae is easily damaged due to heavy burden, which can easily cause back pain. Myofascial release (myofascial release) is a soft tissue massage method that loosens the fascia with hands. By changing the mechanical properties of the muscles, it can loosen over-tension or tense muscles. It is the most commonly used by physical therapists to loosen muscles. One of the operation techniques. However, there is no literature to quantify the effect of myofascial mobilization. The purpose of this experiment is to evaluate whether MyotonPRO can quantify the changes in the muscle characteristics of the erector spinae in different postures and after myofascial relaxation, and to test the validity of the muscle tone tester.

Intervention

Other:
• manual erector spinae myofascial realease
The subjects first positioned the third, fourth, and fifth lumbar vertebrae in a relaxed lying position, about 2-3 cm away from the left and right sides (depending on the size of the subjects' muscles). And then in six postures (prone, prone with leg raise, sit straight , slouch sitting, stand straight and slouch standing), MyotonPRO was used to test the above-mentioned 8 points in these position. Subjects will undergo a pre-mobilization assessment to see if MyotonPRO can detect changes in the erector spinae muscle properties, including changes in muscle tone, stiffness, and elasticity, under different test positions. After physical therapist manual mobilization, MyotonPRO's erector spinae muscle biomechanical data was collected again for data analysis to determine MyotonPRO could objectively quantify changes in erector spinae biomechanical characteristics.
• self-myofascial release technique
The subjects first positioned the third, fourth, and fifth lumbar vertebrae in a relaxed lying position, about 2-3 cm away from the left and right sides (depending on the size of the subjects' muscles). And then in six postures (prone, prone with leg raise, sit straight , slouch sitting, stand straight and slouch standing), MyotonPRO was used to test the above-mentioned 8 points in these position. Subjects will undergo a pre-mobilization assessment to see if MyotonPRO can detect changes in the erector spinae muscle properties, including changes in muscle tone, stiffness, and elasticity, under different test positions. After self mobilization by roller, MyotonPRO's erector spinae muscle biomechanical data was collected again for data analysis to determine MyotonPRO could objectively quantify changes in erector spinae biomechanical characteristics.
