Development and Psychometric Testing of the Japanese Version of the Fremantle Neck Awareness Questionnaire: A Cross-Sectional Study

Body Image Measured via the Fremantle Awareness Questionnaire in Individuals With and Without Pain: A Systematic Review and Meta-Analysis

Research suggests that pain negatively affects body image, and body image may also influence reported pain levels. This review aims to summarize the literature on differences in body image distortion between individuals with pain compared to pain-free individuals. The review was conducted according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses 2020 statement and an a priori preregistered protocol. The literature was searched using 5 electronic databases. Studies assessing body image with the Fremantle Awareness Questionnaire (FAQ) in individuals with and without pain were eligible for inclusion. Screening and selection of eligible studies were performed by independent reviewers. Methodological quality was assessed with the Joanna Briggs Institute critical appraisal tool. Meta-analyses, meta-correlations, and metamean analyses were performed using random-effect models. The primary outcome was the FAQ score; secondary outcomes were reported pain variables. Data from individuals with pain (n = 2277) and without pain (n = 615) were summarized. Significant body image distortions were found in individuals with pain compared to individuals without pain. Compared to pain-free individuals, the pain group rated significantly higher in the FAQ when experiencing back pain (standardized mean differences=1.33, 95% confidence interval=.88-1.77) or other body parts (standardized mean differences=1.25, 95% confidence interval=.51-1.99). The results of meta-correlation analyses confirmed the positive relationship between body image distortion and pain intensity (r = .31), pain at rest (r = .31), or pain during movement (r = .36), but not for pain duration. A difference in mean FAQ results was observed between individuals with pain in different areas (knee and back). PERSPECTIVE: This review confirms differences in body image distortion between pain and pain-free individuals. Pain intensity was correlated with altered body perception, but not pain duration. A moderate correlation was observed between body image distortion and reported pain variables. Body image was more impaired by knee pain than back pain.

Effects of spinal stabilization exercises delivered using telerehabilitation on outcomes in patients with chronic neck pain: a randomized controlled trial

BACKGROUND

When spinal stabilization exercises (SSE) are performed regularly, may provide benefits on outcome measures in chronic nonspecific neck pain (CNNP) patients. The pandemic has made it difficult for CNNP patients to access regular physiotherapy-exercise services. This study aims to compare telerehabilitation (TR) with face-to-face rehabilitation in CNNP.

METHODS

Neck Functional Capacity Evaluation Test (NFCET) results were the primary outcomes. Pain intensity (PI), disability, awareness, neck muscles architecture, andexercise satisfaction were the secondary outcomes. Patients were randomized into the TR group (TRG) (n = 15) and the control group (CG) (n = 16). Patients performed SSE 3 days a week, for 8 weeks. The TRG was instructed remotely while the CG was instructed in the clinic.

RESULTS

After 8 weeks in both groups, NFCET values and neck awareness increased (p < 0.05), PI and disability decreased (p < 0.05).      Muscle architecture improved in both groups (p < 0.05), except for the Right Sternocleidomastoideus in both groups and the Right Upper-Trapezius in TRG (p > 0.05). There was no difference between the groups for all variables and exercise satisfaction(p > 0.05).

CONCLUSION

SSE for CNNP, whether supervised by therapists in the clinic or by telerehabilitation, was equally effective.

Exploratory and confirmatory factor analysis of the new region-generic version of Fremantle Body Awareness-General Questionnaire

BACKGROUND

As the field of pain evaluation grows, newer and more targeted tools are being published for patient-centric evaluation of specific aspects of the pain experience. The Fremantle Back Awareness Questionnaire (FreBAQ) is intended to capture alterations in bodily awareness or perception. To date only region-specific (back, neck, shoulder, knee) versions have been published.

OBJECTIVES

The purpose of our study was to report on the properties of a new region-generic version of the FreBAQ, the FreBAQ-general. Structural validity, internal consistency, and convergent validity against external criteria were evaluated in a sample of Canadian military veterans with chronic pain, with results compared against those published for the region-specific FreBAQ versions.

METHODS

Eligible participants were those that had prior military service, were at least 18 years of age and self-identified as having chronic pain. We used a split-sample approach to Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA) on independent random samples. Factor structure, internal consistency, and associations with external criteria were used to compare against prior versions.

RESULTS

328 respondents (74% of consented) completed at least 7 of the 9 FreBAQ-general questions. EFA and CFA on two independent samples offered support for both 6- and 7-item versions. Comparisons against the external criteria (pain severity, interference, catastrophizing) indicated no statistical superiority of one over the other, so in the interest of parsimony the 6-item FreBAQ-general was endorsed.

CONCLUSIONS

The Fremantle Body Awareness Questionnaire (FreBAQ-general) showed psychometric properties very much in alignment with those previously reported for the region-specific versions, and sound factorial validity accomplished with fewer items (6 vs. 9). We believe this version can be implemented in practice for those seeking a shorter scale without the need to have multiple region-specific versions on hand, though suggest that those seeking direct comparability with previously published work will still wish to use the original versions.

"But it feels swollen!": the frequency and clinical characteristics of people with knee osteoarthritis who report subjective knee swelling in the absence of objective swelling

Supplemental Digital Content is Available in the Text.

The present results support the coexistence of altered body image (subjective without objective swelling) and pain, disability, and maladaptive beliefs in people with knee osteoarthritis.

Introduction:

There are complex interactions between pain and perceptions of the painful body part in musculoskeletal disorders, and disruption of various body representations in people with chronic pain.

Objectives:

The purpose of this study was to investigate how frequently people with knee osteoarthritis (OA) complain of swelling without objective evidence of swelling, and describe the clinical characteristics of this population.

Methods:

Forty-six people with knee OA (68.1 ± 8.8 years) participated in this cross-sectional study. Subjective and objective swelling was evaluated by knee-specific body perception questionnaire and ultrasonography, respectively. Pain intensity, disability, pain-related beliefs, 2-point discrimination threshold, and quadriceps muscle strength were also evaluated.

Results:

Approximately 1/3 of participants (n = 15) had subjective feelings of knee swelling in the absence of objective swelling (S only). Fifteen participants had both subjective and objective knee swelling (S + O group) and 16 had neither subjective nor objective knee swelling (No S/O group). Participants in the S only group had similar pain or disability as those in the S + O group but had more severe pain or disability than those with in the No S/O group. Those in the S only group also had larger 2-point discrimination distance threshold at the medial knee (impaired tactile acuity) than those in the S + O group and had more dysfunctional pain catastrophizing and pain-related self-efficacy than both other groups.

Conclusion:

Our results suggest that about 30% of people with knee OA perceive swelling of the knee in the absence of any objective swelling and that this is accompanied by severe pain and functional disability. Considering altered body image of the knee may reveal relevant treatment-based subgroups in people with knee OA.
