Pragmatic cluster randomised double-blind pilot and feasibility trial of an active behavioural physiotherapy intervention for acute non-specific neck pain: a mixed-methods protocol

Active behavioural physiotherapy intervention for acute non-specific neck pain: a cluster randomised double-blind pilot and feasibility clinical trial

PURPOSE

To evaluate the feasibility of an active behavioural physiotherapy intervention (ABPI) and procedures to prevent the transition to chronicity in patients with acute non-specific neck pain (ANSNP).

MATERIALS AND METHODS

A cluster-randomised double-blind (assessors and participants), parallel 2-arm (ABPI versus standard physiotherapy intervention [SPI]) pilot and feasibility clinical trial was conducted owing to a pre-specified published protocol. Six public hospitals were recruited and cluster-randomised (computer-generated randomisation with block sampling). Sixty participants (30 in each arm, 10 per hospital) were assessed at baseline and 3 months following baseline for neck disability index, numerical pain rating scale, cervical range-of-motion, fear-avoidance beliefs questionnaire and EuroQol 5-dimension 5-level.

RESULTS

All procedures worked well. The participants' median age was 36.5 (range 21-59, interquartile range: 20.75) years. Participants in the ABPI demonstrated better improvement in all outcomes compared to SPI. Furthermore, the number of fully recovered participants following ABPI (27/30, 90.00%) was higher than SPI (16/30, 53.33%) with fewer treatment sessions and lower costs of management.

CONCLUSIONS

The findings suggest that the ABPI is feasible and valuable (e.g. a high number of fully recovered participants, fewer treatment sessions and reduced management costs compared to the SPI) in conducting a future definitive trial to evaluate the effectiveness of the ANSNP management.

Adaptation and psychometric evaluation of the Thai version of the modified STarT Back Screening Tool in individuals with neck pain

BACKGROUND

The modified STarT Back Screening Tool (mSBST) can be used to classify individuals with neck pain (NP) into low, medium, and high risk for chronicity. However, the mSBST-Thai version (mSBST-TH) for NP does not exist.

OBJECTIVES

The aims of this study were to adapt the SBST-TH into the mSBST-TH and evaluate its psychometric properties.

METHODS

The adaptation process committee included one researcher, one musculoskeletal physical therapist, and one Thai linguistic expert. A total of 261 participants (aged 20-70 years) with NP in Phitsanulok Province were invited to complete the mSBST-TH, visual analogue scale, neck disability index, fear-avoidance beliefs questionnaire (FABQ), pain catastrophizing scale, EuroQol five-dimensions five-levels questionnaire (EQ5D-5L), and EQ5D-5L-visual analogue scale (EQ5D-5L-VAS). Fifty participants completed the mSBST-TH twice, with an interval of 48 hours to perform test-retest reliability.

RESULTS

The Cronbach's alpha coefficient of the mSBST-TH total score was 0.73. Factor analysis revealed two components, psychosocial and physical. The intraclass correlation coefficient of test-retest reliability was found to be 0.81 for the total score. Moderate correlations were found between the mSBST-TH and all questionnaires, except for the FABQ-work. The discriminative validity was excellent between the mSBST-TH total score and the EQ5D-5L-VAS. The standard error of measurement and minimal detectable change of the mSBST-TH total score were 0.56 and 1.56, respectively. No significant floor and ceiling effects were found.

CONCLUSION

The mSBST-TH was successfully adapted with no ambiguity reported. Furthermore, the mSBST-TH has presented acceptable psychometric evaluation.

Effectiveness of interventions for middle-aged and ageing population with neck pain: a systematic review and network meta-analysis protocol

INTRODUCTION

Neck pain (NP) is a common musculoskeletal complaint and is increasing in prevalence. Current clinical practice guidelines and systematic reviews recommended conservative, pharmacological and invasive interventions for individuals with NP. However, optimal management specifically for those who are middle-aged or older adults (≥45 years) is not available; and important considering our ageing population.

METHODS AND ANALYSIS

A systematic review with network meta-analysis (NMA) will be conducted following the Cochrane guidelines. Eligibility criteria include randomised controlled/clinical trials evaluating any of acute (<3 months) or chronic (≥3 months) non-specific NP, whiplash associated disorders, cervical radiculopathy and cervicogenic headache. Any interventions and outcome measures detailed within The International Classification of Functioning, Disability and Health domains will be included. Two independent reviewers will search key databases (AMED, CENTRAL, CINAHL, Embase, MEDLINE, PEDro and PsycINFO), grey literature, key journals and reference lists in May 2022. Two reviewers will decide eligibility and assess risk of bias (ROB) of included studies. The kappa statistic will be used to evaluate agreement between the reviewers at each stage. Data will be extracted by one reviewer and checked for accuracy by a second reviewer. Descriptive data and ROB will be summarised and tabulated. Traditional pairwise meta-analysis using random-effect model will be performed for all direct comparisons, and NMA using a frequentist random-effect model then performed based on NP classification where possible. A network of traditional pairwise meta-analysis allows comparisons of multiple interventions from both direct and indirect evidence to provide a hierarchal establishment for enhancing decision making of clinical practitioners.

ETHICS AND DISSEMINATION

Ethic approval is not required as the study is a literature review. The findings will be shared with the national and international researchers, healthcare professionals and the general public through publishing in a peer-reviewed journal and presentations at conferences.

Association between muscle morphology changes, cervical spine degeneration and clinical features in patients with chronic nonspecific neck pain: a magnetic resonance imaging analysis

PURPOSE

The primary objective of the present study was to investigate the correlations among cervical paraspinal muscle morphology changes (fatty infiltration (FI) and muscle atrophy), cervical degeneration and clinical features in patients with chronic nonspecific neck pain (CNSNP).

METHODS

The magnetic resonance imaging (MRI) data of 55 consecutive patients (average age 35.80) with CNSNP were analyzed in this cross-sectional study. Muscle morphology changes in seven groups of paraspinal muscles, indicated by the adjusted cross-sectional area (aCSA) and FI ratio (FI%), were measured from C3/4 to C6/7. The correlations of these changes with disc degeneration, cervical balance (C2-7 angle and cervical alignment) and clinical features (severity of neck pain and related disability and the frequency of acute neck pain (ANP) recurrence) were evaluated.

RESULTS

Significant correlations between FI% and aCSA and the grade of disc degeneration were observed in specific muscle groups at each level (p<0.05). Morphological changes in the deep extensors and superficial paraspinal muscles were significantly associated with cervical balance parameters (p<0.05). The FI% showed a significant positive correlation, while aCSA showed a significant negative correlation with the severity of neck pain and related disability (p<0.05). Correlations between morphological changes and the frequency of ANP recurrence were also present for some muscles (p<0.05).

CONCLUSION

Correlations among muscle morphology changes, cervical degeneration and clinical features were established for patients with CNSNP, and muscle volume changes and FI might affect CNSNP in diverse manners through different paraspinal muscle groups. These results implicated the complex contribution of muscle morphological changes to cervical degeneration and the clinical course of CNSNP.

Translation, cross-cultural adaptation and psychometric evaluation of the Thai version of the fear-avoidance beliefs questionnaire in patients with non-specific neck pain

OBJECTIVES

Fear-avoidance beliefs questionnaire (FABQ) is a self-report, valid and reliable questionnaire to quantify fear and avoidance beliefs related to physical activity and work. Furthermore, it can be used to predict prolong disability in patients with non-specific neck pain. Although it was originally developed to manage patients with low back pain, it has also been studied in individuals with neck pain. This questionnaire was translated into several languages following reports of potential benefits in patients with neck pain. Recently, Thai neck clinical trials, international multi-centre trials and data sharing are growing throughout the world but no validated Thai version of the FABQ is available for clinical and research uses. Our objectives were to translate and cross-culturally adapt the FABQ into Thai version and evaluate its psychometric properties in Thai patients with non-specific neck pain.

METHODS

Cross-cultural translation and adaptation of the FABQ were conducted according to standard guidelines. A total of 129 participants with non-specific neck pain were invited to complete the Thai versions of the FABQ (FABQ-TH), neck disability index and visual analogue scale for pain intensity. Psychometric evaluation included exploratory factor analysis, internal consistency, test-retest reliability, agreement, and convergent validity. Thirty participants completed the FABQ-TH twice with a 48-h interval between tests to assess the test-retest reliability.

RESULTS

Factor analysis identified four components for the FABQ-TH (66.69% of the total variance). The intraclass correlation coefficient of test-retest reliability was excellent for the total score (0.986), work attitudes (0.995), physical activity attitudes (0.958), physical activity experiences (0.927), and expected recovery (0.984). Cronbach's alpha for internal consistency was excellent (range 0.87-0.88) for all items. The minimal detectable change of the FABQ-TH was 5.85. The FABQ-TH correlated to its subscales (range 0.470-0.936), indicating the strongest association with work attitude. The weakest correlation was observed between the FABQ-TH and disability (r _s =0.206, p=0.01). Missing data and significant floor or ceiling effects were not found.

CONCLUSIONS

The Thai version of the FABQ for non-specific neck pain was successfully adapted. It is a valid and reliable instrument to quantify fear and avoidance beliefs among patients with non-specific neck pain who speak and read Thai.
