The assessment of cervical muscle control patterns is important for the diagnosis of cervical dysfunction. Voluntary response index (VRI), including the similarity index (SI) and the magnitude (MAG), provides quantitative analysis of the surface electromyography (sEMG) pattern and total muscle voluntary activities respectively. This study was to investigate the effect of movement directions and speeds of the VRI response of cervical muscles in healthy subjects. The sEMG of bilateral sternocleidomastoid, semispinalis capitis, and splenius capitis were measured in thirteen asymptomatic young subjects. The subjects performed voluntary neck movements in flexion, extension, left and right side bending at fast, medium, and slow speeds. The results showed that SI ranged from 1–0.8 and MAG was generally less than 40 μV. The SI was significantly smallest and the MAG was largest at fast speed. The MAG was also significantly different among directions but the effect of direction on SI was only significant at fast speed. In conclusion, the movement speed and direction could affect the magnitude and control pattern of cervical muscles, such that both the speed and direction of the examined tasks should be carefully monitored during the assessment of cervical muscle activation.
