“…Changes in motion sequence or the stability of the motion may be an expression of altered or disturbed proprioception or neuromuscular control inhibition. In addition, research on the global kinematics of the spine has demonstrated a reduction in the range of motion of the main motion component in the cervical spine due to age [8][9][10][11].…”

Purpose Analyzing and comparing the range of motion and movement pattern of subjects who underwent an anterior cervical fusion using trabecular metal with control subjects. Methods Three-dimensional kinematics of planar active axial rotation and active lateral bending of 50 experimental and 41 control subjects were registered by means of an electromagnetic tracking system. Results Comparing the experimental group with the control group reveals that the range of the main motion component differs significantly (p \ 0.01) during the active axial rotation and lateral bending movement. During active axial rotation, the coupled lateral bending motion component also differs between both groups. The root mean square value of the jerkiness (derivative of the acceleration) and de deviation from the 6-polynomial smoothed function of the main as well as the coupled motion component express the qualitative aspects of kinematics and are significantly different between the experimental and the control group for both movements (p \ 0.05).Conclusions Subjects who have an anterior cervical fusion with trabecular metal show significant quantitative as well as qualitative differences in cervical kinematics during active axial rotation and lateral bending compared to control subjects.

“…29 Total rotation movement (right plus left rotation movement) was analyzed, because it is difficult to precisely determine the neutral position for cervical movements and because previous studies have found a significant effect of the initial head position on active ROM. 9,38 Both groups performed cervical rotation ROM movements in 2 conditions: condition 1, resting scapular position, and condition 2, neutral vertical scapular position. The order of testing of the 2 conditions was randomly assigned such that half of the subjects for each group The ANOVA revealed no significant interaction effect of group by condition (F = 0.19, df = 1, P = .66) or significant main effect of group (F = 0.41, df = 1, P = .53).…”

Changes of the alignment of either the scapulae or the cervical spine can potentially influence the biomechanics of the other by altering the tension at the cervicoscapular muscles. 15 scapula is located between the spinous process of the second and seventh thoracic vertebrae. 14,16,21,27 When the superior angle of the scapula is located below the spinous process of the second thoracic vertebra, the scapula is considered to be depressed. 16,27 It has been proposed that a depressed scapular alignment affects neck function potentially through increasing compressive loading in the neck region, 36 through the transfer of weight from the upper extremities by way of the attachments of the cervicoscapular muscles. 15 A depressed scapular alignment has also been proposed to be related to neck pain, 27,30 and is associated with decreased pressure pain threshold (PPT) in the upper trapezius region. 1 When a depressed scapular alignment is identified in individuals with cervical dysfunction, passively elevating the scapulae can decrease symptoms 27,30,36 and improve ROM. 36 Several studies have investigated the influence of age, 5,7,10,13,17,22,35,38,40 sex, 7,10,13,17,22,35,38,40 and craniocervical posture 7,8,26,38 on cervical ROM.

Assessing healthy subjects could allow us to understand the effect of scapular alignment on cervical spine movement without the influence of pain.The purpose of the current study was to compare (1) active cervical rotation ROM between healthy young subjects It has been suggested that an ideal vertical scapular alignment is when the STUDY DESIGN: Cross-sectional study, quasiexperimental design. OBJECTIVES:To compare the active cervical rotation range of motion (ROM) between healthy young subjects with a neutral vertical scapular alignment and subjects with scapular depression, and to examine the influence of modifying the vertical position of the scapulae on active cervical rotation ROM. BACKGROUND:Altered scapular alignment is proposed to be related to neck dysfunction and pain. Changes in the alignment of either the scapulae or the cervical spine can potentially influence the biomechanics of the other by altering the tension at the cervicoscapular muscles.

IntroductionWalking is for humans one of the most natural activities. However, although it is well known that the lumbar spine is of primary importance in gait [11] and that its development is influenced by the upright posture adopted in human locomotion [21], little is known about the kinematic behavior of the lumbar spine during this daily activity.Several biomechanical aspects of the lumbar spine during walking have been studied previously. For instance, the resultant forces on lumbar discs and facet joints during walking have been shown to reach 2.5 times the body weight [4], although lower and higher peak loads have been described [7,9,13,14]. A recent in vivo study by Wilke et al. [32], for example, showed much lower intradiscal pressures during gait, which were only moderately larger than those registered during relaxed standing or sitting. It is, however, not known whether these pressures are altered in patients with low back disorders. Lumbar loads during gait have been shown to increase with increasing walking velocity [7], although this finding remains controversial [32]. Peak erector spinae contraction forces during walking (140 N) are larger than those of the remaining trunk muscles (about 15 N) [9]. A study by Vink and Karssemeijer [28] showed bilateral activity of Abstract The lumbar spine is of primary importance in gait and its development is influenced by the upright posture adopted in human locomotion. However, little is known about the kinematic behavior of the lumbar spine during walking. The aim of this study was to examine (1) lumbar spine kinematics during walking, (2) the effect of walking velocity on lumbar motion patterns and (3) the coupling characteristics of rotation and bending. In 22 volunteers aged 15-57 years, the three-dimensional displacements of T12 to the sacrum were sampled during elementary movements of the trunk and during walking on a treadmill at four walking velocities. A three-dimensional electrogoniometer (CA 6000 Spine Motion Analyzer) sampling at 100 Hz was used. We analyzed maximal primary and coupled motion ranges (ROM) and velocities in each plane. Lumbar ROM during walking did not exceed 40% of maximal active ROM. Transverse plane ROM and frontal and transverse velocities increased with walking velocity. Coupling of rotation and bending during walking was individually variable and dependent on walking velocity. Moreover, the smoothness of the bending-rotation path varied with walking velocity. A simplified envelope of lumbar coupling characteristics during walking is presented, and the existence of an individually variable walking speed that is characterized by a more harmonic lumbar contribution is hypothesized.
