BACKGROUND: Recent work described parameters of the helical axis in asymptomatic people with potential for investigating kinematic changes in the cervical region. This approach could provide novel information on movement variability in people with neck pain, however this has never been investigated. This study aimed to investigate movement variability during active neck movements performed at different speeds in people with and without chronic neck pain. METHODS: This observational case-control study examined 18 participants with chronic neck pain of either idiopathic or traumatic origin and 18 gender-matched asymptomatic participants. Cervical kinematics were captured with 3D motion capture as people with and without chronic neck pain performed flexion-extension, bilateral lateral flexion and bilateral rotation at different speeds (natural, slow, and fast). The mean distance and mean angle parameters of the helical axis were extracted to describe 3D motion and quantify movement variability. FINDINGS: A smaller mean distance was observed in those with neck pain compared to the asymptomatic participants during flexion-extension (P = 0.019) and rotation movements (P = 0.007). The neck pain group displayed smaller values for the mean angle during rotation movements with different speeds (P = 0.01). These findings indicate less variable movement for those with neck pain relative to the asymptomatic participants. No difference in the mean angle was observed between groups for flexion-extension and lateral flexion. INTERPRETATION: The findings reiterate the importance of data derived from kinematic measures, and its potential for providing clinicians with further insight into the quality of active neck movements in people with chronic neck pain. |

Background: Previous findings reported that people with chronic neck pain walk with reduced range trunk rotation, especially when walking in more challenging conditions. Quantification of the quality of neck and trunk movement during gait could provide further insight into biomechanical changes that occur in people with neck pain. This study uniquely compared the variability of trunk and neck rotation during single-task and dual-task gait in people with chronic neck pain and asymptomatic individuals. Methods: An observational case-control study was conducted on 20 asymptomatic individuals and 24 people with chronic neck pain of idiopathic or traumatic origin. Participants performed rectilinear walking whilst keeping the head in a neutral position (single-task) and whilst rotating the head at a natural speed (dual-task). Trunk and head rotation angles were averaged across gait cycles for the task trials. The data were normalised in time, and the average variability of angular distribution along the normalised cycle was extracted. The Tampa Scale for Kinesiophobia was used to assess fear of movement. Findings: During single-task gait, there were no group differences for the variability of trunk (p = 0.862) or neck (p = 0.427) rotation. For dual-task gait, there was no difference between groups for the variability of neck rotation (p = 0.636), however, the participants with neck pain displayed reduced variability of trunk rotation (p = 0.021). The neck pain group also walked at a significantly slower speed during dual-task gait (p = 0.043) compared to asymptomatic individuals and the speed of their gait was associated with the extent of fear of movement. Interpretation: The strategy observed in participants with chronic neck pain likely reflects adaptive behaviour when faced with more challenging conditions for postural control. |

People with acute neck pain commonly present with restricted neck movement. However, it is unknown whether the presence of acute pain affects the quality of neck movement, specifically neck movement variability. We examined the effects of acute neck muscle soreness induced via eccentric exercise in healthy volunteers, on the variability of neck movement by examining changes in parameters of the helical axis during active neck movements. An experimental, single-arm repeated measures study recruited 32 healthy participants, male and female, aged between 18 and 55 years. Repetitive active neck movements (flexion–extension, bilateral lateral flexion and bilateral rotation) were performed at different speeds, either at full range of motion (RoM) or restricted to 45° RoM at baseline, pre-exercise (T0), immediately following eccentric neck exercise (T1), 24 h (T2) and 48 h post-exercise (T3). The mean distance (MD) and mean angle (MA) parameters of the helical axis were extracted to quantify movement variability. MD, measured during movements performed at full RoM, reduced significantly at T2 compared to T0 (P = 0.001) regardless of direction or speed of movement. MA was significantly lower at T2 and T3 compared to T1 (P = 0.029 and P = 0.033, respectively). When RoM was restricted to 45°, significantly lower MD values were observed at T3 compared to T1 (P = 0.034), and significantly lower MA values were measured at T3 compared to T0, T1 and T2 (all P < 0.0001). This study uniquely demonstrates that neck movement variability is reduced immediately after, 24 h and 48 h after eccentric exercise, indicating that acute neck muscle soreness modifies the quality of neck movement. |

People With Chronic Neck Pain Perform Active Neck Movements In A Less Variable Way |
ملخص المشاركة: |
Background: As well as pain, people with chronic neck pain (CNP) typically present with functional impairments including decreased range of neck motion. While most studies have focused on the quantity of movement, typically measuring static variables during planar cervical motion, knowledge of the quality and variability of movement may provide more detaliled and precise information of movement deficits in people with CNP. Purpose: This study investigated the variability of active neck movement in people with CNP compared to healthy people, using measures of the helical axis (HA) to identify differences in movement variability. Methods: An observational case-control study was conducted in a laboratory setting following ethical approval. The sample comprised asymptomatic (n=18) and CNP (n=18) participants. The CNP group presented with a Neck Disability Index (NDI) score of mean(SD): 12.94(6.84), pain intensity using the Numerical Rating Scale (NRS) of 4.08(1.89) Tampa Scale for Kinesiophobia (TSK) of 36.53(6.58). Participants performed 10 repetitions of flexion-extension, bilateral lateral flexion and bilateral rotation movements at different speeds (at a natural self-selected speed, slow speed (30 beats per second (bps)) and fast speed (60 bps)) as cervical kinematic data was recorded using a 3D motion capture system (BTS Bioengineering, Milan,Italy). Mean distance (MD) and mean angle (MA) parameters of the HA were extracted to examine 3Dmotion and movement variability. Two-way analysis of variance (ANOVA) was used to evaluate MD and MA between groups, with lower values indicative of less movement variability. Results: A smaller MD during flexion-extension (p=0.019) and rotation movements (p=0.007) was observed in participants with CNP compared to asymptomatic participants. The mean(SD) for the CNP participants at a natural speed was: flexion-extension 1.46cm(0.33) and rotation 0.83cm(0.15), whereas for asymptomatic participants values were 1.61cm(0.28) and 1.07cm(0.33) respectively. No difference between groups was observed for MD measured during lateral flexion (p=0.28). In addition, smaller values of the MA (p< 0.05) were observed in the CNP group during rotation at different speeds.The mean (SD) for the CNP group were as follows: natural speed 4.98°(0.85), slow speed 4.89°(0.71), and fast speed 3.98°(0.42). The asymptomatic group valueswere: natural speed 5.21°(1.04), slow speed 5.44°(1.64), and fast speed 4.99°(1.02). No difference in MA parameters was observed between groups for flexion-extension (p=0.92) or lateral flexion (p=0.21) movements. Conclusion(s): This is the first study to evaluate the variability of active neck movement in people with CNP by utilising parameters of the HA. Decreased movement variability was observed in people with CNP, especially during flexion-extension and rotation movements. These results provide novel insights regarding neck movement behaviour in people with CNP, which may have implications for the persistence of pain. Implications: Examining neck movements using HA parameters can be difficult in typical clinical settings. However, the findings reiterate the importance of data derived from kinematic measures, and its potential for giving clinicians further insight into active neck movement behaviour in people with CNP. Further studies should evaluate movement measures that are simple to collect and use in a clinical setting. These measures have potential for identifying changes in movement quality in people with CNP. Keywords: 1.

People with Chronic Neck Pain Perform Active Neck Movements in A Less Variable Way |
ملخص المشاركة: |
Purpose: Besides pain, individuals with chronic neck pain (CNP) may present with a number of functional impairments including decreased range of motion. Most studies have focused on the quantity of movement, typically static variables during planar cervical motion, yet the quality and variability of movement may be a better indicator of ongoing neuromuscular dysfunction in people with CNP. This study investigated the variability of active neck movement in people with CNP compared to healthy individuals via measures of the helical axis (HA) to identify potential changes in movement variability. Methods: An observational case-control study was conducted and a sample of 36 gender-matched subjects, including 18 asymptomatic people and 18 people with CNP of idiopathic or traumatic origin, attended a single laboratory session. A 3D motion capture system enabled acquisition of cervical kinematic data. Participants performed flexion-extension, bilateral lateral flexion and bilateral rotation movements at different speeds, with eyes open and eyes closed. Each condition included 10 repetitions of the movement. The mean distance (MD) and mean angle (MA) parameters of the HA were extracted to describe three-dimensional motion and quantity movement variability. Two-way analysis of variance (ANOVA) was used to evaluate MD and MA between groups. Lower values of the MD and MA indicate less movement variability. Results: A smaller MD during flexion-extension (p = 0.18) and rotation movements (p = 0.0009) were observed in those with CNP compared to asymptomatic participants. There were no differences between groups for MD measured during lateral flexion. In addition, the CNP group displayed smaller values for the MA of the rotation movements for all conditions (p = 0.001). No difference in the MA was observed between groups for flexion-extension and lateral flexion movements. Conclusion(s): The present study is the first to evaluate the variability of active neck movement in people with CNP by utilising parameters of the HA. Decreased movement variability was observed in individuals with CNP, especially during flexion-extension and rotation movements. These results provide novel insight regarding neck movement behaviour in people with CNP which may have implications for the persistence of pain. Implications: Although examining neck movements using HA parameters can be difficult in typical clinical settings, the findings reiterate the importance of data derived from kinematic measures, and its potential for giving clinicians further insight into active neck movement behaviour in people with CNP.

Investigating Neck and Trunk Movement Variability During Single and Dual-Task Gait in People with Chronic Neck Pain |
ملخص المشاركة: |
Purpose: Chronic Neck Pain (CNP) is a common musculoskeletal condition that contributes greatly to health service costs. In addition to pain and disability, CNP may lead to neuromuscular and biomechanical disturbances. Little is known regarding gait in people with CNP, even though walking is one of most common daily activities. Performance of two tasks at the same time (dual tasks) is typical of daily activities involving gait. Thus, examining dual-task walking may provide further insight regarding gait biomechanics in people with CNP. Methods: An observational case-control design was conducted with 20 healthy individuals and 24 people with CNP of idiopathic or traumatic origin. Participants walked in a straight line (3 meters) with their head in a neutral position (single-task) and the same task whilst rotating their head continuously at a normal speed (dual-task). The average of trunk and head rotation angles (degrees) were calculated across gait cycles for the task trials. The average variability of the angular distribution along the normalised cycle was calculated after the data were normalised in time (% gait cycle). The same analysis method was used for the dual-task trials, but head rotation angular peaks were used as events to define gait cycles. One-way analysis of variance (ANOVA) or Kruskal-Wallis H tests were performed to evaluate the variability of trunk and neck rotation and mean gait speed during single- and dual-task gait trials. Results: No group differences were observed for the variability of trunk (p = 0.862) or neck (p = 0.427) rotation during single-task gait trials. For dual-task gait, no significant difference was found between groups for the variability of neck rotation (p = 0.636). However, the participants with CNP showed reduced variability of trunk rotation (p = 0.021). Furthermore, a significantly slower speed during dual-task gait was observed in the CNP group (p = 0.043) as compared to healthy individuals. Conclusion(s): This study is the first to examine the variability of trunk and neck rotation in people with and without CNP while performing single-task or dual-task gait trials. These results show less variability of trunk rotation and slower gait speed in people with CNP as compared to helathy individuals when performing the more challenging task (the dual-gait task). Implications: The results of dual-task trials reveal changes in movement variability in people with CNP. These observations confirm of the importance of evaluating movement behaviour during functional tasks.
