Overview
Brief Summary
The purpose of this study is to termine if a different attentional focus would alter the motor control in cervical muscles during the cranio-cervical test.
Detailed Description
Asymptomatic subjects will be recruited to this study. Superficial electromyography of the Sternocleidomastoid, Range of Motion (ROM) and Cranio-Cervical Flexion Test (CCFT) will be measured before, immediately after change in focus of attention, 2 days after training under a particular focus of attention, and 7 days after training the task under the same focus of attention. Subjects will be randomized into three groups: Internal focus of attention, external focus of attention and control group.

Outcomes
Primary Outcomes
Change from baseline in Electromyographic Activity of Sternocleidomastoid
Time Frame: Baseline, Immediately after baseline, Post-Training (2 days after the baseline), Retention (7 days after finished training)
The Electromyography (EMG) signal amplitude will be determined by the root mean square (RMS) value computed over intervals of 1 s during each 10-s contraction. RMS will be expressed as a percentage of the maximum RMS value during the reference voluntary contraction.
Secondary Outcomes
- Cranio-cervical Range of Motion(Baseline, Immediately after baseline, Post-Training (2 days after the baseline), Retention (7 days after finished training))
- Cranio-Cervical Flexion Test Performance(Baseline, Immediately after baseline, Post-Training (2 days after the baseline), Retention (7 days after finished training))
