“…These findings, are consistent with previous evidence (Sjölander et al , 2006, Roijezonet al, 2010, Sarig Bahatet al, 2010, Tsang et al , 2014, and also support the validity of the newer version of VR system used here as the presented results replicated our previous findings of significantly less mean and peak velocities in those with neck pain compared to control individuals (Sarig Bahatet al, 2010). The current study also demonstrated differences with respect to motion smoothness (NVP) and symmetry (TTPP).…”

“…Theoretically, normal voluntary motion should have a near symmetrical bell-shaped velocity profile with a single velocity peak and equal acceleration and deceleration phases (Vikne et al , 2013). Studies have consistently showed that velocity and smoothness of cervical motion is reduced in patients with chronic neck pain (Sjölander et al , 2008, Roijezon et al , 2010, Tsang et al , 2013 and motion accuracy is impaired when compared to asymptomatic individuals (Kristjansson and Oddsdottir, 2010, Roijezonet al, 2010, Sarig Bahatet al, 2010, Woodhouse et al , 2010b.…”

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.

“…However, it is not known whether kinematic changes relate mainly to quantitative aspects of the motion. Beside kinematic disturbances in quantitative aspects like Range of Motion (RoM) and motion coupling patterns, qualitative changes have been suggested [4][5][6][7]. Changes in motion sequence or the stability of the motion may be an expression of altered or disturbed proprioception or neuromuscular control inhibition.…”

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.

Background and ObjectiveIn the presence of pain, whether clinical or experimentally induced, individuals commonly show impairments in the control of muscle force (commonly known as force steadiness). In this systematic review and meta‐analysis, we synthesized the available evidence on the influence of clinical and experimental pain on force steadiness.Databases and Data TreatmentMEDLINE, EMBASE, PubMed, CINAHL Plus and Web of Science databases were searched from their inception to 19 December 2023, using MeSH terms and pre‐selected keywords related to pain and force steadiness. Two independent reviewers screened studies for inclusion and assessed their methodological quality using a modified Newcastle–Ottawa risk of bias tool.ResultsIn total, 32 studies (19 clinical pain and 13 experimental pain) were included. Meta‐analyses revealed reduced force steadiness in the presence of clinical pain as measured by the coefficient of variation (CoV) and standard deviation (SD) of force (standardized mean difference; SMD = 0.80, 95% CI = 0.31–1.28 and SMD = 0.61, 95% CI = 0.11–1.11). These findings were supported by moderate and low strength of evidence respectively. In the presence of experimental pain, meta‐analyses revealed reductions in force steadiness when measured by the CoV of force but not by the SD of force (SMD = 0.50, 95% CI = 0.01–0.99; and SMD = 0.44, 95% CI = −0.04 to 0.92), each supported by very low strength of evidence.ConclusionsThis work demonstrates that pain, particularly clinical pain, impairs force steadiness. Such impairments likely have clinical relevance and could become targets for treatment when managing people experiencing musculoskeletal pain.Significance StatementThis systematic review and meta‐analyses enhances our understanding of motor impairments observed in people experiencing musculoskeletal pain. It underscores the significance of incorporating force steadiness assessment when managing individuals experiencing musculoskeletal pain. Additionally, it suggests that future research should explore the potential benefits of force steadiness training in alleviating patients' symptoms and enhancing their functional performance. This could potentially lead to the development of innovative therapeutic approaches for individuals suffering from musculoskeletal pain.
