  • The Effect of Neck-specific Exercise With, or Without a Behavioral Approach, on Pain, Disability, and Self-Efficacy in Chronic Whiplash-associated Disorders A Randomized Clinical Trial
  • 2015

    • <p>Objectives: The aim of this study was to compare the effect on self-rated pain, disability, and self-efficacy of 3 interventions for the management of chronic whiplash-associated disorders: physiotherapist-led neck-specific exercise (NSE), physiotherapist-led NSE with the addition of a behavioral approach, or Prescription of Physical Activity (PPA). Materials and Methods: A total of 216 volunteers with chronic whiplash-associated disorders participated in this randomized, assessor blinded, clinical trial of 3 exercise interventions. Self-rated pain/pain bothersomeness (Visual Analogue Scale), disability (Neck Disability Index), and self-efficacy (Self-Efficacy Scale) were evaluated at baseline and at 3 and 6 months. Results: The proportion of patients reaching substantial reduction in pain bothersomness (at least 50% reduction) was more evident (P less than 0.01) in the 2 NSE groups (29% to 48%) compared with the PPA group (5%) at 3 months. At 6 months 39% to 44% of the patients in the 2 neck-specific groups and 28% in the PPA group reported substantial pain reduction. Reduction of disability was also larger in the 2 neck-specific exercise groups at both 3 and 6 months (P less than 0.02). Self-efficacy was only improved in the NSE group without a behavioral approach (P = 0.02). However, there were no significant differences in any outcomes between the 2 physiotherapist-led NSE groups. Discussion: NSE resulted in superior outcomes compared with PPA in this study, but the observed benefits of adding a behavioral approach to the implementation of exercise in this study were inconclusive.</p>

  • Cervical Muscle Activity During Loaded Arm Lifts in Patients 10 Years Postsurgery for Cervical Disc Disease
  • 2013

  • Does posture of the cervical spine influence dorsal neck muscle activity when lifting?
  • 2014
  • Ingår i: Manual Therapy. - Elsevier. - 1356-689X .- 1532-2769. ; 19:1, s. 32-36

    • <p>Previous studies have shown that postural orientations of the neck, such as flexed or forward head postures, are associated with heightened activity of the dorsal neck muscles. While these studies describe the impact of variations in neck posture alone, there is scant literature regarding the effect of neck posture on muscle activity when combined with upper limb activities such as lifting. The purpose of this study was to evaluate the effect of three different neck postures on the activity of the different layers of the dorsal neck muscles during a lifting task. Ultrasound measurements of dorsal neck muscle deformation were compared over two time points (rest, during lift) during a lifting task performed in three different neck postural conditions (neutral, flexed and forward head posture) in 21 healthy subjects. Data were analysed by post-process speckle tracking analysis. Results demonstrated significantly greater muscle deformation induced by flexed and forward head postures, compared to the neutral posture, for all dorsal neck muscles at rest (p &lt; 0.05). Significant condition by time interactions associated with the lift was observed for four out of the five dorsal muscles (p &lt; 0.02). These findings demonstrate that posture of the cervical spine influenced the level of muscle deformation not only at rest, but also when lifting. The findings of the study suggest that neck posture should be considered during the evaluation or design of lifting activities as it may contribute to excessive demands on dorsal neck muscles with potential detrimental consequences.

  • Is there a difference in the pattern of muscle activity when performing neck exercises with a guild board versus a pulley?
  • 2013
  • Ingår i: Journal of Rehabilitation Medicine. - Stiftelsen Rehabiliteringsinformation. - 1650-1977 .- 1651-2081. ; 45:9, s. 900-905

    • <p><strong>Objective</strong>: Guild boards and pulleys are apparatus commonly used to train cervical muscle function for their purported benefit in facilitating activity of the deeper muscle layers, although this effect has not been substantiated. The objective of this study was to compare the activity of the different layers of cervical muscles when performing exercise with these 2 types of apparatus.</p><p><strong>Subjects</strong>: A total of 19 healthy persons (mean age 28 years, (standard deviation 7 years).</p><p><strong>Design</strong>: Ultrasound measurements of muscle deformation and deformation rate were recorded from the dorsal and ventral neck muscle layers during extension and flexion exercises. Pulley exercises were performed in the upright sitting position against a standardized resistance (men 2 kg, women 1 kg) and guild board exercises at an angle of 45 degrees.</p><p><strong>Results</strong>: The dorsal muscles generally showed greater levels of deformation and deformation rate during exercise with the guild board compared with the pulley system (p&lt;0.05), but with no significant differences in relative activity between the deep and superficial muscle layers (condition x muscle interaction (p&gt;0.05)). No differences were observed for the ventral muscles between exercise methods (p&gt;0.05).</p><p><strong>Conclusion</strong>: While both exercise methods appear to train cervical muscle function, neither appear to be more selective in facilitating deep cervical muscle activity, probably as they involve very similar cervical kinematics.</p>

  • THE EFFECT OF 3 DIFFERENT EXERCISE APPROACHES ON NECK MUSCLE ENDURANCE, KINESIOPHOBIA, EXERCISE COMPLIANCE, AND PATIENT SATISFACTION IN CHRONIC WHIPLASH
  • 2015
  • Ingår i: Journal of Manipulative and Physiological Therapeutics. - 0161-4754 .- 1532-6586. ; 38:7, s. 465-476

    • <p>Objective: The purpose of this study was to compare the effects of 3 different exercise approaches on neck muscle endurance (NME), kinesiophobia, exercise compliance, and patient satisfaction in patients with chronic whiplash. Methods: This prospective randomized clinical trial included 216 individuals with chronic whiplash. Participants were randomized to 1 of 3 exercise interventions: neck-specific exercise (NSE), NSE combined with a behavioral approach (NSEB), or prescribed physical activity (PPA). Measures of ventral and dorsal NME (endurance time in seconds), perceived pain after NME testing, kinesiophobia, exercise compliance, and patient satisfaction were recorded at baseline and at the 3- and 6-month follow-ups. Results: Compared with individuals in the prescribed physical activity group, participants in the NSE and NSEB groups exhibited greater gains in dorsal NME (P = .003), greater reductions in pain after NME testing (P = .03), and more satisfaction with treatment (P &lt; .001). Kinesiophobia and exercise compliance did not significantly differ between groups (P &gt; .07). Conclusion: Among patients with chronic whiplash, a neck-specific exercise intervention (with or without a behavioral approach) appears to improve NME. Participants were more satisfied with intervention including neck-specific exercises than with the prescription of general exercise.</p>

  • Ultrasound imaging of dorsal neck muscles with speckle tracking analyses the relationship between muscle deformation and force
  • 2019
  • Ingår i: Scientific Reports. - Nature Publishing Group. - 2045-2322 .- 2045-2322. ; 9
  • Tidskriftsartikel (refereegranskat)abstract
    • <p>The development of methods of non-invasive measurement of neck muscle function remains a priority in the clinical sciences. In this study, dorsal neck muscle deformation vs time curves (deformation area) were evaluated against incremental force, recorded from non-invasive real-time ultrasound measurement. The results revealed subject-specific moderate to strong linear or non-linear relationships between deformation and force. Test-retest variability showed strong reliability for all five neck muscles summed together and fair to good reliability for the five muscles evaluated separately. Multivariate statistics were used to analyse the interactions between the dorsal neck muscles during different percentages of maximal voluntary contraction (MVC). Low force (10-20% MVC) was related to muscle shortening; higher force (40-80% MVC) showed combination of shortening and elongation deformation in the muscle interactions. The muscle interactions during isometric MVC test were subject-specific, with different combinations and deformations of the five neck muscles. Force &gt;= 40% MVC were associated with a forward movement of the cervical spine that affected the ultrasound measurement of the dorsal neck muscles. Ultrasound with speckle-tracking analyses may be best used to detect low levels (&lt;40% MVC) of neck muscle activity.</p>
