Design outcomes

Primary

Measure	Time frame
The square root is calculated neck muscle signal. And by dividing the value of the root of the second root of the muscle in the case of complete bending over its value in the maximum muscle activity (MVC), a value (ratio) for each muscle is obtained. This number will be the criterion for judging muscle activity and relaxation flexion. Timepoint: Flexion relaxation is measured at the beginning of the study (before the intervention) and 8 weeks after the start of the exercise. Method of measurement: Electromyography.	—
