Fear and avoidance of activity may play a role in fostering disability in whiplash-associated disorders (WAD). This study examined the role of fear after WAD and assessed the effectiveness of 3 treatments targeting fear. People still symptomatic from WAD grade I-II injuries approximately 3months previously (n=191) completed questionnaires (eg, Neck Disability Index [NDI]) and were randomized to 1 of the treatments: (1) informational booklet (IB) describing WAD and the importance of resuming activities, (2) IB+didactic discussions (DD) with clinicians reinforcing the booklet, and (3) IB+imaginal and direct exposure desensitization (ET) to feared activities. DD and ET participants received three 2-hour treatment sessions. Absolute improvements in NDI were in predicted direction (ET=14.7, DD=11.9, IB=9.9). ETs reported significantly less posttreatment pain severity compared with the IB (Mean=1.5 vs 2.3, P<.001, d=0.6) and DD (M=1.5 vs 2.0, P=.039, d=0.6) groups. Reduction in fear was the most important predictor of improvement in NDI (β=0.30, P<.001), followed by reductions in pain (β=0.20, P=.003) and depression (β=0.18, P=.004). The mediational analysis confirmed that fear reduction significantly mediated the effect of treatment group on outcome. Results highlight the importance of fear in individuals with subacute WAD and suggest the importance of addressing fear via exposure therapy and/or educational interventions to improve function.

<b>PURPOSE: </b>Although there is growing evidence in favour of the bio-psychosocial approach to the treatment of persistent neck pain, it is questioned whether treating psychological factors can improve patient perceptions of disability, pain and quality of life. This randomised, controlled study with 12 months' follow-up was conducted to evaluate the efficacy of adding cognitive-behavioural principles to exercises for chronic neck pain.<b>METHODS: </b>Eighty patients were randomly assigned to the usual neck exercises plus cognitive-behavioural treatment (PTcb group, 40 subjects) or to treatment based on neck exercises alone (PT group, 40 subjects). Before treatment (T1), at the end of treatment (T2) and 12 months later (T3), all of the patients completed a booklet including the Neck Pain and Disability Scale, a numerical rating scale, and the Short-Form Health Survey Questionnaire (SF-36).<b>RESULTS: </b>The present trial failed to demonstrate its primary end point: the pre- and post-treatment difference in total NPDS scores was not statistically different between groups. Disability improved similarly in both groups over time, remaining stable until T3 in the PTcb group and slightly increasing at the same time in the PT group. Pain trends were comparable, with both groups showing an improvement between T1 and T2, and a slight worsening between T2 and T3. There were significant increases in all of the SF-36 domains except for health in general, and vitality in both groups by the end of treatment. SF-36 showed a between-group difference only for the physical activity domain (10.4; 95% CI 2.4-18.5).<b>CONCLUSION: </b>Disability, pain and quality of life improved at the end of treatment in both groups, without differences between them.
OBJECTIVES: : Whiplash-associated disorders (WAD) are common and involve both physical and psychological impairments. Research has shown that persistent posttraumatic stress symptoms are associated with poorer functional recovery and physical therapy outcomes. Trauma-focused cognitive-behavioral therapy (TF-CBT) has shown moderate effectiveness in chronic pain samples. However, to date, there have been no clinical trials within WAD. Thus, this study will report on the effectiveness of TF-CBT in individuals meeting the criteria for current chronic WAD and posttraumatic stress disorder (PTSD). METHOD: : Twenty-six participants were randomly assigned to either TF-CBT or a waitlist control, and treatment effects were evaluated at posttreatment and 6-month follow-up using a structured clinical interview, self-report questionnaires, and measures of physiological arousal and sensory pain thresholds. RESULTS: : Clinically significant reductions in PTSD symptoms were found in the TF-CBT group compared with the waitlist at postassessment, with further gains noted at the follow-up. The treatment of PTSD was also associated with clinically significant improvements in neck disability, physical, emotional, and social functioning and physiological reactivity to trauma cues, whereas limited changes were found in sensory pain thresholds. DISCUSSION: : This study provides support for the effectiveness of TF-CBT to target PTSD symptoms within chronic WAD. The finding that treatment of PTSD resulted in improvements in neck disability and quality of life and changes in cold pain thresholds highlights the complex and interrelating mechanisms that underlie both WAD and PTSD. Clinical implications of the findings and future research directions are discussed.
STUDY DESIGN: An economic evaluation alongside a randomized controlled trial comparing behavioral graded activity (BGA) with manual therapy (MT).
OBJECTIVE: To evaluate the cost-effectiveness of BGA in comparison with MT for patients with subacute neck pain from a societal perspective.
SUMMARY OF BACKGROUND DATA: Neck pain is common and poses an important socioeconomic burden to society. Data on the cost-effectiveness of treatments for neck pain are scarce.
METHODS: A randomized clinical trial was conducted, involving 146 patients with subacute nonspecific neck pain. The BGA program can be described as a time-contingent increase in activities from baseline toward predetermined goals. MT consists of specific spinal mobilization techniques and exercises. Clinical outcomes included recovery, pain, disability, and quality-adjusted life-years (QALYs). Costs were measured from a societal perspective using cost diaries. The follow-up period was 52 weeks. Multiple imputation was used for missing cost and effect data. Uncertainty surrounding cost differences and incremental cost-effectiveness ratios was estimated using bootstrapping. Cost-effectiveness planes and cost-effectiveness acceptability (CEA) curves were estimated.
RESULTS: BGA had no significant effect on recovery or QALYs gained in comparison with MT but pain and disability did improve significantly in the BGA group in comparison with the MT group. Total societal costs in the BGA group were nonsignificantly higher than in the MT group. Cost-effectiveness analyses showed that BGA is not cost-effective in comparison with MT for recovery and QALYs gained. Substantial investments are needed to reach a 0.95 probability that BGA is cost-effective in comparison with MT for pain and disability.
CONCLUSION: On the basis of the data presented, we consider BGA not cost-effective in comparison with MT.
Regular physical exercise is a cornerstone in rehabilitation programs, but adherence to comprehensive exercise remains low. This study determined the effectiveness of small daily amounts of progressive resistance training for relieving neck/shoulder pain in healthy adults with frequent symptoms; 174 women and 24 men working at least 30 h per week and with frequent neck/shoulder pain were randomly assigned to resistance training with elastic tubing for 2 or 12 minutes per day 5 times per week, or weekly information on general health (control group). Primary outcomes were changes in intensity of neck/shoulder pain (scale 0 to 10), examiner-verified tenderness of the neck/shoulder muscles (total tenderness score of 0 to 32), and isometric muscle strength at 10 weeks. Compared with the control group, neck/shoulder pain and tenderness, respectively, decreased 1.4 points (95% confidence interval -2.0 to -0.7, p<0.0001) and 4.2 points (95% confidence interval -5.7 to -2.7, p<0.0001) in the 2-minute group and 1.9 points (95% confidence interval -2.5 to -1.2, p<0.0001) and 4.4 points (95% confidence interval -5.9 to -2.9, p<0.0001) in the 12-minute group. Compared with the control group, muscle strength increased 2.0 Nm (95% confidence interval 0.5 to 3.5Nm, p=0.01) in the 2-minute group and 1.7Nm (95% confidence interval 0.2 to 3.3 Nm, p=0.02) in the 12-minute group. In conclusion, as little as 2 minutes of daily progressive resistance training for 10 weeks results in clinically relevant reductions of pain and tenderness in healthy adults with frequent neck/shoulder symptoms. Trial registration: www.isrctn.org/ISRCTN60264809. In generally healthy adults with frequent neck/shoulder muscle pain, as little as 2 minutes of daily progressive resistance training reduces pain and tenderness.
STUDY DESIGN: A randomized clinical trial. OBJECTIVE: To compare the effectiveness of a behavioral graded activity program with manual therapy in patients with subacute (4-12 weeks) nonspecific neck pain. SUMMARY OF BACKGROUND DATA: Neck pain is a common complaint, for which many conservative therapies are available in primary care. There is strong evidence for manual therapy in combination with exercises. Psychosocial factors are also believed to play a role in chronic pain. The evidence of the effectiveness of a program focused on these factors is still unknown. METHODS: A randomized clinical trial was conducted, involving 146 patients with subacute nonspecific neck pain. The BGA program can be described as a time-contingent increase in activities from baseline toward predetermined goals. Manual therapy consists of specific spinal mobilization techniques and exercises. Primary outcomes were global perceived effect, the Numerical Rating Scale for pain and the Neck Disability Index. Secondary outcomes were the Tampa Scale for Kinesiophobia, the 4 Dimensional Symptom Questionnaire, and the Pain Coping and Cognition List. Measurements were carried out at baseline and 6, 13, 26, and 52 weeks after randomization. Data are analyzed according to the intention-to-treat principle, using multilevel analysis. RESULTS: The success rates at 52 weeks, based on the GPE were 89.4% for the BGA program and 86.5% for MT. This difference was not statistically significant. For pain and disability, a difference was found in favor of the BGA program; mean difference for pain = 0.99 (95% CI 0.15-1.83) and mean difference for NDI = 2.42 (95% CI 0.52-4.32). All other differences between the interventions in the primary and secondary outcomes were not statistically significant. CONCLUSION: Based on this trial it can be concluded that there are only marginal, but not clinically relevant, differences between a BGA program and MT.
