Treatment based classification systems for patients with non-specific neck pain. A systematic review.

OBJECTIVE: We aimed to identify published classification systems with a targeted treatment approach (treatment-based classification systems (TBCSs)) for patients with non-specific neck pain, and assess their quality and effectiveness. DESIGN: Systematic review. DATA SOURCES: MEDLINE, CINAHL, EMBASE, PEDro and the grey literature were systematically searched from inception to December 2019. STUDY APPRAISAL AND SYNTHESIS: The main selection criterium was a TBCS for patients with non-specific neck pain with physiotherapeutic interventions. For data extraction of descriptive data and quality assessment we used the framework developed by Buchbinder et al. We considered as score of ≤3 as low quality, a score between 3 and 5 as moderate quality and a score ≥5 as good quality. To assess the risk of bias of studies concerning the effectiveness of TBCSs (only randomized clinical trials (RCTs) were included) we used the PEDro scale. We considered a score of ≥ six points on this scale as low risk of bias. RESULTS: Out of 7664 initial references we included 13 studies. The overall quality of the TBCSs ranged from low to moderate. We found two RCTs, both with low risk of bias, evaluating the effectiveness of two TBCSs compared to alternative treatments. The results showed that both TBCSs were not superior to alternative treatments. CONCLUSION: Existing TBCSs are, at best, of moderate quality. In addition, TBCSs were not shown to be more effective than alternatives. Therefore using these TBCSs in daily practice is not recommended.

Prognostic factors for persistent pain after a first episode of nonspecific idiopathic, non-traumatic neck pain: A systematic review.

BACKGROUND: Prognosis of acute idiopathic neck pain is poor. An overview of modifiable and non-modifiable prognostic factors for the development of chronic musculoskeletal neck pain after an episode of idiopathic, non-traumatic neck pain is needed. OBJECTIVE: Identify prognostic factors for pain intensity and perceived non-recovery at three, six and 12 months after a first episode of idiopathic, non-traumatic neck pain. STUDY DESIGN: Systematic review METHODS: Systematic literature search up to October 21, 2017 for prospective prognostic studies with main outcomes perceived non-recovery and pain intensity. The QUIPS was used for quality assessment. RESULTS: Out of 2737 screened articles six prospective studies with high-risk-of-bias were identified, analyzing 47 and 43 factors for the outcome variables 'pain intensity' and 'perceived non-recovery', respectively. Based on univariate- and multivariate analyses we found moderate evidence for 'age> 40 years' and 'concomitant back pain' to be prognostic for 'pain intensity'. For the outcome 'perceived non-recovery' at 12 months, we found moderate evidence for both 'a previous period of neck pain' and 'accompanying headache' as prognostic variables for persistent pain, based on univariate analysis. No prognostic factor was found which was retained in more than one multivariate analysis for the outcome variable 'perceived non-recovery'. However, the quality of the evidence for these prognostic factors was low to very low. CONCLUSION: This review identifies prognostic factors for neck pain, of which only a few are modifiable. Further research is needed before drawing definite conclusions about the prognostic value of these factors.

Fear-avoidance beliefs are associated with a high fat content in the erector spinae: a 1.5 tesla magnetic resonance imaging study.

Background: Intramuscular adipose tissue (IMAT) is a feature of degenerative muscle composition and is a common feature in populations with chronic low back pain (CLBP). Avoidance behavior is a possible cause of morphological muscle composition due to disuse of the paraspinal muscles. Therefore it is of clinical interest to determine the association between fear-avoidance beliefs and IMAT of the paraspinal muscles in populations with CLBP. Methods: In this cross-sectional study, we examined twenty-four adults, featuring a mean age of 48.63 years (SD ± 14.73), with CLBP. Axial T2-weighted Magnetic Resonance Imaging (MRI) images were selected on the same level as the intervertebral disc of segments L4-L5 and L5-S1. After determine the region of interest, the amount of IMAT was measured by an automatic-threshold method to distinguish fat from muscle tissue. Fear-avoidance beliefs were measured with the Fear-Avoidance Beliefs Questionnaire, with regard to Physical Activity (FABQ-PA). Bivariate correlation and multiple regression analysis were used to determine the association between IMAT of the paraspinal muscles and fear-avoidance beliefs. Results: There is a significant bivariate association between the FABQ-PA and ES IMAT (r = 0.484, P = 0.017), but not for LMM (r = 0.228, P = 0.284). The association between the FABQ-PA and ES IMAT remained moderate after adjusting for covariates (ß = 0.381, P = 0.028). Conclusion: Fear-avoidance beliefs are moderately associated with ES IMAT and poorly associated with LMM IMAT in a population with CLBP. Results should be interpreted with caution due to a small and selected study population.

The Association of Illness Perception and Prognosis for Pain and Physical Function in Patients With Noncancer Musculoskeletal Pain: A Systematic Literature Review.

BACKGROUND: In the literature, illness perceptions have been reported to be important psychological factors associated with pain intensity and physical function in individuals with musculoskeletal pain. OBJECTIVE: To assess the relationship of illness perceptions with pain intensity and physical function in individuals with noncancer musculoskeletal pain. METHODS: In this systematic review, relevant literature databases, including PubMed, Embase, PsycINFO, CINAHL, and SPORTDiscus, were searched from inception through December 12, 2017. Two authors (E.D.R. and H.W.) independently performed the search procedures, according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses and the A MeaSurement Tool to Assess systematic Reviews guidelines, and the risk-of-bias assessment, using the QUality In Prognosis Studies tool. A qualitative best-evidence synthesis was performed. RESULTS: A total of 26 articles were included in the review. There were 11 cross-sectional studies concerning associations of illness perceptions with pain intensity and 11 cross-sectional studies of associations of illness perceptions with physical function. For the prognosis of pain intensity by illness perceptions, the authors found 4 longitudinal studies, and for the prognosis of physical function by illness perceptions, the authors found 12 longitudinal studies. All studies except 1 had high risk of bias. Across 15 cross-sectional studies on 9 different musculoskeletal conditions, the researchers found limited to moderate evidence for a consistent direction of the relationship of illness perceptions with pain intensity and physical function. Higher maladaptive illness perceptions imply stronger pain intensity and more limitation in physical function. Evidence in longitudinal studies is lacking, especially on pain. CONCLUSION: There is limited to moderate evidence for the cross-sectional relationship between illness perceptions and various musculoskeletal conditions. The prognostic value, however, remains unclear. Future research is recommended to investigate the longitudinal relationship between illness perception domains and outcomes in greater detail.

The clinical reasoning process in randomized clinical trials with patients with non-specific neck pain is incomplete: A systematic review.

OBJECTIVE: Primarily to evaluate the completeness of the description of the clinical reasoning process in RCTs with patients with non-specific neck pain with an argued or diagnosed cause i.e. an impairment or activity limitation. Secondly, to determine the association between the completeness of the clinical reasoning process and the degree of risk of bias. DATA SOURCES: Pubmed, Cinahl and PEDro were systematically searched from inception to July 2016. STUDY SELECTION: RCTs (n = 122) with patients with non-specific neck pain receiving physiotherapy treatment published in English were included. DATA EXTRACTION: Data extraction included study characteristics and important features of the clinical reasoning process based on the Hypothesis-Oriented Algorithm for Clinicians II (HOAC II)]. DATA SYNTHESIS: Thirty-seven studies (30%) had a complete clinical reasoning process of which 8 (6%) had a 'diagnosed cause' and 29 (24%) had an 'argued cause'. The Spearmans rho association between the extent of the clinical reasoning process and the risk of bias was -0.2. CONCLUSIONS: In the majority of studies (70%) the described clinical reasoning process was incomplete. A very small proportion (6%) had a 'diagnosed cause'. Therefore, a better methodological quality does not necessarily imply a better described clinical reasoning process.

Illness perceptions and activity limitations in osteoarthritis of the knee: a case report intervention study.

This case report describes the process and outcome of an intervention where illness perceptions (IPs) were targeted in order to reduce limitations in daily activities. The patient was a 45-year-old woman diagnosed with posttraumatic secondary osteoarthritis of the lateral patella-femoral cartilage of the right knee. At baseline, the patient reported maladaptive IPs on the Brief Illness Perception Questionnaire Dutch Language Version and limitations in walking stairs, cycling and walking. Fewer limitations in daily activities are hypothesized by changing maladaptive IPs into more favourable IPs. In this case report, discussing maladaptive IPs with the patient was the main intervention. A participatory decision making model was used as a design by which the maladaptive IP were discussed. Six out of eight maladaptive IPs changed favourably and there was a clinically relevant decrease in limitations of daily activities. The Global Perceived Effect was rated as much improved.

Cross-cultural adaptation and measurement properties of the Brief Illness Perception Questionnaire-Dutch Language Version.

OBJECTIVE: Ever since Engel's Biopsychosocial Model (1977) emotions, thoughts, beliefs and behaviors are accepted as important factors of health. The Brief Illness Perception Questionnaire (Brief IPQ) assesses these beliefs. Aim of this study was to cross-culturally adapt the Brief IPQ into the Brief IPQ Dutch Language Version (Brief IPQ-DLV), and to assess its face validity, content validity, reproducibility, and concurrent validity. METHODS: Beaton's guideline was used for cross-culturally adaptation. Face and content validity were assessed in 25 patients, 15 physiotherapists and 24 first-grade students. Reproducibility was established in 27 individuals with chronic obstructive pulmonary disease using Cohen's kappa coefficient (K(w)) and the Smallest Detectable Change (SDC). Concurrent validity was assessed in 163 patients visiting 11 different physical therapists. RESULTS: The Brief IPQ-DLV is well understood by patients, health care professionals and first-grade students. Reliability at 1 week for the dimensions Consequences, Concern and Emotional response K(w)>0.70, for the dimensions Personal control, Treatment control, Identity, K(w)<0.70. A time interval of 3 weeks, reliability coefficients were lower for almost all dimensions. SDC was between 2.45 and 3.37 points for individual measurement purposes and between 0.47 and 0.57 points for group evaluative measurement purposes. Concurrent validity showed significant correlations (P<.05) for four out of eight illness perceptions (IPs) dimensions. CONCLUSION: The face and content properties were found to be acceptable. The reproducibility and concurrent validity needs further investigated.
