研究概览
简要总结
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.
详细描述
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.

研究组 & 干预措施
Internal Focus of Attention
30 subjects will be randomized to this arm. Only internal focus of attention feedback instructions will be given during the execution and training performing the Cranio-Cervical Flexion Test. The subjects allocated to this arm will not be allowed to use the visual feedback traditionally provided during the Cranio-cervical Flexion Test.
干预措施: Internal Focus of Attention (Other)
External Focus of Attention
30 subjects will be randomized to this arm. Only external focus of attention feedback instructions will be given during the execution and training performing the Cranio-Cervical Flexion Test. The subjects allocated to this arm will not be allowed to use the visual feedback traditionally provided during the Cranio-cervical Flexion Test. In addition, they will use just a laser point attached to the head to guide their cranio-cervical flexion.
干预措施: External Focus of Attention (Other)
Control
30 subjects will be randomized to this arm. The participants allocated to this arm will be instructed as traditionally during the Cranio-Cervical Flexion Test. They will be given visual feedback while have their attention guided to the inner neck movement.
干预措施: Control (Other)
结局指标
主要结局
Change from baseline in Electromyographic Activity of Sternocleidomastoid
时间窗: 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.
次要结局
- 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))
