“…Thirdly, there were no significant difference of the cervical ROM between the healthy and the neck pain subjects. This could be due to only young subjects were recruited, and the ROM in our study was within pain-free range about threequarters of the maximal active ROM reported in literature (60-70°d uring flexion/extension) (Lantz et al, 2003). Finally, the number of subjects was relatively small.…”

“…First, the ROM in this study was the range where subjects felt mild resistance. It was smaller than the maximal active ROM reported in the literature (60°-70°during flexion/extension and 40°-45°d uring lateral bending) (Lantz et al 2003). At the maximal range of motion, the antagonistic activities decrease according to the flexion-relaxation phenomenon (Meyer et al 1993), and the agonistic activities significantly increase to maintain the maximal position (Harms-Ringdahl and Ekholm 1986).…”

Co-contraction of cervical muscles during sagittal and coronal neck motions at different movement speeds

Muscle co-contraction is important in stabilizing the spine. The effects of movement speed and direction on the cervical co-contraction were, however, not yet investigated. Surface electromyographies of three paired cervical muscles were measured in 17 young healthy subjects. The subjects performed voluntary neck movements in sagittal and coronal plane at fast, medium, and slow speeds. The co-contraction ratio was defined as the normalized integration of antagonistic electromyographic activities divided by that of total muscle activities. The results showed that the co-contraction ratio at fast speed (0.42 +/- 0.21) was smaller than that at medium (0.45 +/- 0.20) and slow (0.46 +/- 0.19) speeds (P

“…Cervical rotations were faster than flexion and extension which has been shown before (Dvir et al , 2006, SarigBahatet al, 2014. Research also shows higher repeatability and sensitivity of horizontal measures relative to sagittal ones (Dall'Alba et al , 2001, Lantz et al , 2003, Dviret al, 2006, Sarig-Bahatet al, 2010 as well as greater ROM in the horizontal plane (Chen et al , 1999, Sarig-Bahatet al, 2010. These findings may have functional significance for rehabilitation.…”

Interactive cervical motion kinematics: Sensitivity, specificity and clinically significant values for identifying kinematic impairments in patients with chronic neck pain

Interactive cervical motion kinematics: sensitivity, specificity and clinically significant values for identifying kinematic impairments in patients with chronic neck pain. AbstractChronic neck pain has been consistently shown to be associated with impaired kinematic control including reduced range, velocity and smoothness of cervical motion, that seem relevant to daily function as in quick neck motion in response to surrounding stimuli. The objectives of this study were: to compare interactive cervical kinematics in patients with neck pain and controls; to explore the new measures of cervical motion accuracy; and to find the sensitivity, specificity, and optimal cutoff values for defining impaired kinematics in those with neck pain.In this cross-section study, 33 patients with chronic neck pain and 22 asymptomatic controls were assessed for their cervical kinematic control using interactive virtual reality hardware and customized software utilizing a head mounted display with built-in head tracking.Outcome measures included peak and mean velocity, smoothness (NVP), symmetry (TTPP), and accuracy of cervical motion.Results demonstrated significant and strong effect-size differences in peak and mean velocities, NVP and TTPP in all directions excluding TTPP in left rotation, and good effect-size group differences in 5/8 accuracy measures.Regression results emphasized the high clinical value of neck motion velocity, with very high sensitivity and specificity (85%-100%), followed by motion smoothness, symmetry and accuracy. These finding suggest cervical kinematics should be evaluated clinically, and screened by the provided cut off values for identification of relevant impairments in those with neck pain. M A N U S C R I P T A C C E P T E D ACCEPTED MANUSCRIPTSuch identification of presence or absence of kinematic impairments may direct treatment strategies and additional evaluation when needed.
