Are patient expectations associated with treatment outcomes in individuals with chronic low back pain? A systematic review of randomised controlled trials

Prehabilitation: The underutilised weapon for chronic pain management

Objective

Prehabilitation encompasses preparatory clinical intervention(s) delivered during the period between diagnosis and treatment commencement. Despite widespread successful usage preoperatively, psychological prehabilitation is neglected in outpatient chronic pain management. Although pain management waitlists are associated with treatment attrition and psychological and physical decline, this time window is underutilised in preventing escalation. Waitlists present an under-explored opportunity to 'prehabilitate' patients waiting for treatment. This topical review aimed to: (1) examine the effectiveness of psychological prehabilitation for pain services; (2) evaluate the psychological and physical decline associated with waiting for pain management; (3) highlight key psychological prehabilitative targets for increasing treatment engagement; (4) promote pain management psychological prehabilitation within personalised pain medicine, building recommendations for future interventions.

Methods

Studies regarding the impact of waitlists and prehabilitation for chronic pain were reviewed.

Results

Findings demonstrated that the psychological constructs of patient expectations, health locus of control, self-efficacy and pain catastrophizing dynamically influence attrition, treatment engagement and outcomes while waiting. These constructs are amenable to change, emphasising their potential utility within a targeted waitlist intervention.

Conclusions

Prehabilitating chronic pain patients towards treatment engagement could circumvent cycles of failed treatment seeking, preventing psychological and physical decline, and reducing healthcare utilisation. Utilising the waitlist to identify psychosocial risk factors (external health locus of control, low self-efficacy and high pain catastrophizing) would identify who requires additional support to prevent increased risk of treatment failure, enhancing personalised care before prescribed treatment is accessed. This review cements the urgent need for pain services to engage proactively with prehabilitation innovation.

Clinimetric Properties of the Working Alliance Inventory and Credibility Expectancy Questionnaire: Screening Options for Musculoskeletal Pain

OBJECTIVE

To investigate clinimetric properties of 2 surveys used to evaluate common factors in the patient-provider relation and present screener options for the assessment of common factors and report their correlation with pain and functional outcomes.

DESIGN

Observational cohort.

SETTING

Outpatient physical therapy.

PARTICIPANTS

100 individuals (58% women, mean age=34, SD=15; N=100) presenting to physical therapy with musculoskeletal pain in the following regions: 44% lower extremity, 36% spine, 19% upper extremity, 1% undetermined.

INTERVENTION

Not applicable.

MAIN OUTCOME MEASURES

Participants completed the Working Alliance Inventory (WAI) and the Credibility and Expectancy Questionnaire (CEQ). Exploratory factor analysis (EFA) explored factor structure of the WAI and CEQ. Internal consistency was evaluated for scales derived from items retained based on factor loadings. Finally, options for screener tools were proposed and assessed based on their correlation to original surveys as well as pain and functional outcomes.

RESULTS

The data supported a 4-factor structure for the surveys. Some WAI items were excluded due to cross-loading. The derived four-factor scales demonstrated strong correlations with the original surveys (r=.89-.99) and exhibited good internal consistency (α=.824-.875). Two screening options were suggested: 1 retaining 11 of the original 18 items and the other comprising just 3 items. Both screening tools correlated with the original surveys and showed associations with improvements in pain and functional outcomes (r=-.21-.34).

CONCLUSION

The proposed screeners provide concise measurement options to facilitate use in clinical practice. These tools can aid in facilitating patient communication specifically addressing patient expectation and understanding the tasks required to enact behavior change.

The Treatment Expectation Questionnaire Tool: A Cross-Cultural Adaptation and Psychometric Evaluation in Turkey

Patients' general treatment expectations are an important indicator of the outcomes of the various treatments they will receive. There is a need for valid and reliable assessment tools that measure the expectations of patients receiving rehabilitation services. This study aimed to translate and validate the Treatment Expectations Questionnaire (TR.TEX-Q) in Turkish patients to assess their treatment-specific expectations. 150 physiotherapy patients were enrolled in the study. The original version of the Treatment Expectation Questionnaire was translated into Turkish. Cronbach's α was used to investigate internal consistency. Intraclass correlation coefficients were used to assess test-retest reliability. Pearsons's correlation was used to calculate convergent and divergent validity. Principal component analysis produced a 15-items scale which had a 6-factors structure. Cronbach's α values ranged from .649 to .879. Test-retest reliability was high for total score and for all subscales. The ICC was between .622 and .852, p < .001. TR.TEX-Q showed good convergent validity, a moderate correlation was found between the Positivity Scale (rho = .45, p < .001). For divergent validity, low to moderate correlation was found between the TR.TEX-Q and the HADS scores. The Turkish version of Treatment Expectation Questionnaire has good reliability and validity data in terms of evaluating the treatment expectations of patients who will receive physiotherapy.

Will you get what you want? Treatment goals and expectations of patients with femoroacetabular impingement syndrome regarding physiotherapist-led treatment

OBJECTIVE: To (i) investigate the goals and expectations of participants enrolled in a clinical trial of physiotherapist-led treatment for femoroacetabular impingement (FAI) syndrome and (ii) explore associations between their expectations and self-reported hip burden and kinesiophobia. METHODS: Data from 150 participants with FAI syndrome who participated in a clinical trial were analysed. Participants described their most important treatment goal and the expectation of achieving this goal throughout physiotherapy treatment. The International Hip Outcome Tool (iHOT-33) subscales were used to assess self-reported hip burden. The Tampa Scale for Kinesiophobia was used to assess kinesiophobia. Participants goals were qualitatively analysed using content analysis. Linear regression was used to explore associations between patient expectations and iHOT and Tampa Scale for Kinesiophobia scores. RESULTS: Participants with FAI syndrome reported goals relating to exercise (52%), improving activities of daily living quality (23%), improving physical function (15%), and reducing pain (10%). Negative expectations regarding physiotherapist-led treatment were reported by 68% of participants. Those with negative expectations reported worse scores for the iHOT-Total score (mean difference = 12 points, 95%CI = [4 to 19]), and iHOT-Symptoms (14 points, [7 to 21]) and iHOT-Social (11 points, [2 to 21]) subscales compared to those with positive expectations. Treatment expectations were not associated with iHOT-Sport, iHOT-Job, and Tampa Scale for Kinesiophobia scores (p > 0.05). CONCLUSION: Patients with FAI syndrome had a generally negative expectation of physiotherapist-led treatment. There was a mismatch between patients' goals and current treatment approaches. Participants with FAI syndrome and negative expectations reported worse quality of life, symptoms, and social concerns than those with positive expectations.

Educational needs and preferences of adult patients with acute pain: a mixed-methods systematic review

ABSTRACT

Many patients experience acute pain, which has been associated with numerous negative consequences. Pain education has been proposed as a strategy to improve acute pain management. However, studies report limited effects with educational interventions for acute pain in adults, which can be explained by the underuse of the person-centered approach. Thus, we aimed to systematically review and synthetize current evidence from quantitative, qualitative and mixed-methods studies describing patients' needs and preferences for acute pain education in adults. We searched original studies and gray literature in 7 databases, from January 1990 to October 2023. Methodological quality was assessed with the Mixed Methods Appraisal Tool. A total of 32 studies were included (n = 1847 patients), two-thirds of which were qualitative studies of high methodological quality. Most of the studies were conducted over the last 15 years in patients with postsurgical and posttraumatic pain, identified as White, with a low level of education. Patients expressed the greatest need for education when it came to what to expect in pain intensity and duration, as well how to take the medication and its associated adverse effects. The most frequently reported educational preferences were for in-person education while involving caregivers and to obtain information first from physicians, then by other professionals. This review has highlighted the needs and preferences to be considered in pain education interventions, which should be embedded in an approach cultivating communication and partnership with patients and their caregivers. The results still need to be confirmed with different patient populations.

One spinal manipulation session reduces local pain sensitivity but does not affect postural stability in individuals with chronic low back pain: a randomised, placebo-controlled trial

BACKGROUND

Clinical practice guidelines recommend spinal manipulation for patients with low back pain. However, the effects of spinal manipulation have contradictory findings compared to placebo intervention. Therefore, this study investigated the immediate effects of lumbar spinal manipulation on pressure pain threshold (PPT) and postural stability in people with chronic low back pain (cLBP). Second, we investigated the immediate effect of lumbar spinal manipulation on pain intensity and the interference of the participant beliefs about which treatment was received in the PPT, postural stability, and pain intensity.

METHODS

A two-arm, randomised, placebo-controlled, double-blind trial was performed. Eighty participants with nonspecific cLPB and a minimum score of 3 on the Numeric Pain Rating Scale received one session of lumbar spinal manipulation (n = 40) or simulated lumbar spinal manipulation (n = 40). Primary outcomes were local and remote PPTs and postural stability. Secondary outcomes were pain intensity and participant's perceived treatment allocation. Between-group mean differences and their 95% confidence intervals (CIs) estimated the treatment effect. One-way analysis of covariance (ANCOVA) was performed to assess whether beliefs about which treatment was received influenced the outcomes.

RESULTS

Participants had a mean (SD) age of 34.9 (10.5) years, and 50 (62.5%) were women. Right L5 [between-group mean difference = 0.55 (95%CI 0.19 to 0.90)], left L5 [between-group mean difference = 0.45 (95%CI 0.13 to 0.76)], right L1 [between-group mean difference = 0.41 (95%CI 0.05 to 0.78)], left L1 [between-group mean difference = 0.57 (95%CI 0.15 to 0.99)], left DT [between-group mean difference = 0.35 (95%CI 0.04 to 0.65)], and right LE [between-group mean difference = 0.34 (95%CI 0.08 to 0.60)] showed superior treatment effect in the spinal manipulation group than sham. Neither intervention altered postural stability. Self-reported pain intensity showed clinically significant decreases in both groups after the intervention. A higher proportion of participants in the spinal manipulation group achieved more than two points of pain relief (spinal manipulation = 90%; sham = 60%). The participants' perceived treatment allocation did not affect the outcomes.

CONCLUSION

One spinal manipulation session reduces lumbar pain sensitivity but does not affect postural stability compared to a sham session in individuals with cLPB. Self-reported pain intensity lowered in both groups and a higher proportion of participants in the spinal manipulation group reached clinically significant pain relief. The participant's belief in receiving the manipulation did not appear to have influenced the outcomes since the adjusted model revealed similar findings.

Racial Differences in Movement-Related Appraisals and Pain Behaviors Among Adults With Chronic Low Back Pain

Research documents racial disparities in chronic low back pain (CLBP). Few studies have examined racial disparities in movement-related appraisals and no studies have examined anticipatory appraisals prior to or pain behaviors during functional activities among individuals with CLBP. This cross-sectional study examined racial differences in anticipatory appraisals of pain, concerns about harm, and anxiety, appraisals of pain and anxiety during movement, and observed pain behaviors during 3 activities of daily living (supine-to-standing bed task, sitting-to-standing chair task, floor-to-waist lifting task) in a sample (N = 126) of non-Hispanic Black (31.0%), Hispanic (30.2%), and non-Hispanic White (38.9%) individuals with CLBP. Hispanic participants reported more expected pain, concerns about harm, and pre-movement anxiety prior to the bed and chair tasks compared to non-Hispanic White participants. Hispanic participants reported more pain during the bed task and more anxiety during the bed and chair tasks compared to non-Hispanic White participants. Non-Hispanic Black participants reported more expected pain, concerns about harm, and pre-movement anxiety prior to the bed task and more pre-movement anxiety prior to the chair task compared to non-Hispanic White participants. Non-Hispanic Black participants reported more anxiety during the bed and chair tasks compared to non-Hispanic White participants. Non-Hispanic Black participants were observed to have significantly more verbalizations of pain during the bed task compared to non-Hispanic White participants. Current findings identify racial disparities in important cognitive-behavioral and fear-avoidance mechanisms of pain. Results indicate a need to revisit traditional theoretical and treatment models in CLBP, ensuring racial disparities in pain cognitions are considered. PERSPECTIVE: This study examined racial disparities in anticipatory and movement-related appraisals, and pain behaviors during activities of daily living among Non-Hispanic Black, Non-Hispanic White, and Hispanic individuals with CLBP. Racial disparities identified in the current study have potentially important theoretical implications surrounding cognitive-behavioral and fear-avoidance mechanisms of pain.

Self-management including exercise, education and activity modification compared to usual care for adolescents with Osgood-Schlatter (the SOGOOD trial): protocol of a randomized controlled superiority trial

BACKGROUND

Osgood-Schlatter is the most frequent growth-related injury affecting about 10% of physically active adolescents. It can cause long-term pain and limitations in sports and physical activity, with potential sequela well into adulthood. The management of Osgood-Schlatter is very heterogeneous. Recent systematic reviews have found low level evidence for surgical intervention and injection therapies, and an absence of studies on conservative management. Recently, a novel self-management approach with exercise, education, and activity modification, demonstrated favorable outcomes for adolescents with patellofemoral pain and Osgood-Schlatter in prospective cohort studies.

AIM

The aim of this trial is to assess the effectiveness of the novel self-management approach compared to usual care in improving self-reported knee-related function in sport (measured using the KOOS-child 'Sport/play' subscale) after a 5-month period.

METHODS

This trial is a pragmatic, assessor-blinded, randomized controlled trial with a two-group parallel arm design, including participants aged 10-16 years diagnosed with Osgood-Schlatter. Participants will receive 3 months of treatment, consisting of either usual care or the self-management approach including exercise, education, and activity modification, followed by 2 months of self-management. Primary endpoint is the KOOS-child 'Sport/play' score at 5 months. This protocol details the planned methods and procedures.

DISCUSSION

The novel approach has already shown promise in previous cohort studies. This trial will potentially provide much-needed level 1 evidence for the effectiveness of the self-management approach, representing a crucial step towards addressing the long-term pain and limitations associated with Osgood-Schlatter.

Correspondence between Expected, Perceived, and Measured Effects of BoNT-A Treatment in Calf Muscles among Children and Adolescents with Cerebral Palsy: A Mixed Methods Study

(1) Background: Our study explores the relationship between expected, perceived, and measured effects of botulinum toxin A (BoNT-A) treatment and saline (placebo) in children and adolescents with cerebral palsy (CP) in the calf muscles of 20 children and adolescents with cerebral palsy (CP), aged 4-15 years, using the Gross Motor Function Classification System (GMFCS) I-II. (2) Methods: A mixed methods parallel database design was used. Quantitative and qualitative data were collected at baseline and four weeks after treatment. The primary quantitative measure was gross energy cost (EC) during walking, obtained from a 5-Minute Walk Test (5MWT), while qualitative semi-structured interviews were performed with each parent and child/adolescent individually. (3) Results: Four weeks after treatment, we did not find any correspondence between expected, measured, and perceived effects. Interestingly, parental perceptions of treatment effects were more consistent than the measured outcomes. We also observed a connection between parental treatment expectations and perceived effects, often related to reduced energy expenditure. Children tended to view their parents as treatment experts and had fewer expectations and perceptions themselves. (4) Conclusions: These findings support the importance of child-centered care, which entails actively listening to children's expectations and perceptions during the treatment process.

Participants' experiences and acceptability of a home-based walking exercise behaviour-change intervention (MOtivating Structure walking Activity in people with Intermittent Claudication (MOSAIC))

OBJECTIVES

This study explored the experiences and acceptability of a novel, home-based, walking exercise behaviour-change intervention (MOtivating Structured walking Activity in people with Intermittent Claudication (MOSAIC)) in adults with Peripheral Arterial Disease (PAD).

DESIGN AND SETTING

Individual semi-structured audio-recorded interviews were conducted with adults with Peripheral Arterial Disease who had completed the MOSAIC intervention as part of a randomised clinical trial. Data were analysed using inductive reflexive thematic analysis and interpreted using the seven-construct theoretical framework of acceptability of healthcare interventions (TFA).

PARTICIPANTS

Twenty participants (mean age (range) 67(54-80) years, 70% male, 55% White British) were interviewed.

RESULTS

One central theme was identified: Acceptability of walking exercise as a treatment. This theme was explained by four linked themes: Exploring walking exercise with a knowledgeable professional, Building confidence with each step, Towards self-management-learning strategies to continue walking and The impact of walking exercise. These themes were interpreted using six of the seven TFA constructs: affective attitude, burden, perceived effectiveness, intervention coherence, opportunity costs, and self-efficacy.

CONCLUSIONS

Participants perceived MOSAIC as an effective, acceptable, and low burden intervention. Physiotherapists were regarded as knowledgeable and supportive professionals who helped participants understand PAD and walking exercise as a treatment. Participants developed confidence to self-manage their condition and their symptoms. As participants confidence and walking capacity improved, they expanded their activities and gained a more positive outlook on their future. MOSAIC is an acceptable intervention that may facilitate adoption of and access to exercise for people with PAD.

IMPLICATIONS FOR PRACTICE

Healthcare provider perspectives on integrating a comprehensive spine care model in an academic health system: a cross-sectional survey

BACKGROUND

Healthcare systems (HCS) are challenged in adopting and sustaining comprehensive approaches to spine care that require coordination and collaboration among multiple service units. The integration of clinicians who provide first line, evidence-based, non-pharmacological therapies further complicates adoption of these care pathways. This cross-sectional study explored clinician perceptions about the integration of guideline-concordant care and optimal spine care workforce requirements within an academic HCS.

METHODS

Spine care clinicians from Duke University Health System (DUHS) completed a 26-item online survey via Qualtrics on barriers and facilitators to delivering guideline concordant care for low back pain patients. Data analysis included descriptive statistics and qualitative content analysis.

RESULTS

A total of 27 clinicians (57% response) responded to one or more items on the questionnaire, with 23 completing the majority of questions. Respondents reported that guidelines were implementable within DUHS, but no spine care guideline was used consistently across provider types. Guideline access and integration with electronic records were barriers to use. Respondents (81%) agreed most patients would benefit from non-pharmacological therapies such as physical therapy or chiropractic before receiving specialty referrals. Providers perceived spine patients expected diagnostic imaging (81%) and medication (70%) over non-pharmacological therapies. Providers agreed that receiving imaging (63%) and opioids (59%) benchmarks could be helpful but might not change their ordering practice, even if nudged by best practice advisories. Participants felt that an optimal spine care workforce would require more chiropractors and primary care providers and fewer neurosurgeons and orthopedists. In qualitative responses, respondents emphasized the following barriers to guideline-concordant care implementation: patient expectations, provider confidence with referral pathways, timely access, and the appropriate role of spine surgery.

CONCLUSIONS

Spine care clinicians had positive support for current tenets of guideline-concordant spine care for low back pain patients. However, significant barriers to implementation were identified, including mixed opinions about integration of non-pharmacological therapies, referral pathways, and best practices for imaging and opioid use.

Interprofessional Active Learning for Chronic Pain: Transforming Student Learning From Recall to Application

Chronic pain (CP) affects over 50 million Americans daily and represents a unique challenge for healthcare professionals due to its complexity. Across all health professions, only a small percentage of the curriculum is devoted to treating patients with CP. Unfortunately, much of the content is delivered passively via lecture without giving students an opportunity to practice the communication skills to effectively treat patients in the clinic. An interprofessional team of health educators identified 5 essential messages that students frequently struggle to convey to patients with CP. Those messages were based on interprofessional and profession-specific competencies to treat patients with CP from the International Association for the Study of Pain. The 5 messages highlighted the importance of (1) therapeutic alliance, (2) consistent interdisciplinary language, (3) patient prognosis, (4) evidence for pain medicine, surgery, and imaging, and (5) early referral to the interprofessional team. For each message, the team summarized relevant research supporting the importance of each individual message that could serve as a foundation for didactic content. The team then developed active learning educational activities that educators could use to have students practice the skills tied to each message. Each learning activity was designed to be delivered in an interprofessional manner.

Do patients’ pre-treatment expectations about acupuncture effectiveness predict treatment outcome in patients with chronic low back pain? A secondary analysis of data from a randomised controlled clinical trial

Objective

This secondary analysis of a randomised controlled patient-blinded trial comparing effectiveness and side effect briefings in patients with chronic low back pain (CLBP) investigated the association between patients’ pre-treatment expectations about minimal acupuncture treatment and pain intensity as outcome during and after the end of the treatment.

Methods

Chronic low back pain patients with a pain intensity of at least 4 on a numeric rating scale from 0 to 10 received eight sessions of minimal acupuncture treatment over 4 weeks. The primary outcome was change in pain intensity rated on a Numerical Rating Scale (NRS 0–10) from inclusion visit to treatment session 4 and to the end of the treatment. Patients’ expectations about the effectiveness of acupuncture were assessed using the Expectation for Treatment Scale (ETS) before randomization. Linear regression was applied to investigate whether patients’ pre-treatment expectations predicted changes in pain intensity during and after treatment.

Results

A total of 142 CLBP patients (40.1 ± 12.5 years; 65.5% female) were included in our analysis. Patients’ pre-treatment expectations about acupuncture treatment were associated with changes in pain intensity after four sessions of minimal acupuncture treatment (b = -0.264, p = 0.002), but not after the end of the treatment. This association was found in females and males.

Conclusions

Our results imply that higher pre-treatment expectations only lead to larger reductions in pain intensity in the initial phase of a treatment, with a similar magnitude for both females and males. As the treatment progresses in the second half of the treatment, adapted expectations or other non-specific effects might play a more important role in predicting treatment outcome.

The association between patients' illness perceptions and longitudinal clinical outcome in patients with low back pain

Initial perceptions regarding prognosis and treatment effects were prominent perceptions explaining longitudinal outcomes in patients with low back pain, including explaining patients' development of self-management strategies.

Introduction:

Illness perception is suggested to influence outcome in patients with low back pain (LBP). It is unknown if specific illness perceptions are of more importance for longitudinal outcomes, including development of self-management strategies.

Objectives:

This study explores whether patients' initial illness perceptions were associated with disability, pain, health-related quality of life, and self-care enablement outcomes in patients with LBP after 3 and 12 months.

Methods:

Four hundred sixty-seven consecutive patients seeking physiotherapeutic primary care for LBP were eligible to participate in this prospective cohort study, providing data at baseline and after 3 and 12 months (mean age 45 years, 56% women). Multiple linear regression analysis was used to explore whether patients' illness perceptions at baseline were associated with outcome in the Oswestry Disability Index (ODI), Numeric Rating Scale–LBP (NRS-LBP), EuroQol Five Dimensions, and Patient Enablement Instrument (PEI).

Results:

Stronger beliefs that the back problem will last a long time at baseline were associated with worse outcome in ODI, NRS-LBP, and PEI at 3 and 12 months and in EuroQol Five Dimensions at 12 months. Negative beliefs regarding treatment's ability to improve LBP were associated with worse outcome in NRS-LBP and PEI at 3 and 12 months and in ODI at 12 months.

Conclusions:

Illness perceptions regarding prognosis and treatment's ability to improve symptoms were the most prominent perceptions explaining several longitudinal clinical outcomes. These expectations should be addressed in an early stage in the delivery of interventions for LBP. These expectations were also important for patients' development of coping and self-management strategies.

Participants' experiences from group-based treatment at multidisciplinary pain centres - a qualitative study

OBJECTIVES

The aim of the study was to explore the experiences of participants in non-pharmacological group-based treatments delivered as part of a randomised controlled trial at Norwegian tertiary care pain centres.

METHODS

Individual semi-structured interviews with 15 persons were conducted. The data were analysed with a descriptive thematic cross-case analysis based on the method of systematic text condensation.

RESULTS

All participants talked about some aspects of the group-based treatments as a positive experience, but mainly the outcome was in line with their expectations; they hoped it would reduce their pain but did not expect it. There were no clear-cut differences in the experiences between the participants from the two different intervention groups. The content was experienced as both relevant and interesting but also to introduce concepts that were difficult to grasp and understand. Similarly, the experiences of participating in a group-based treatment were mostly stimulating but could also be challenging because of an expectancy of sharing personal stories. Although experiencing few changes to their pain they came away with techniques and lessons that were valuable to them.

CONCLUSIONS

In this study, taking part in group-based treatment was perceived as giving positive and valuable lessons, due to relevant content and learning from the professionals and fellow participants, but without any clear indication of reduced pain. Approval from ethical committee number 10260 REK Midt.

Unraveling Negative Expectations and Nocebo-Related Effects in Musculoskeletal Pain

This Perspective adapts the ViolEx Model, a framework validated in several clinical conditions, to better understand the role of expectations in the recovery and/or maintenance of musculoskeletal (MSK) pain. Here, particular attention is given to the condition in which dysfunctional expectations are maintained despite no longer being supported by confirmatory evidence (i.e., belief-lifting the arm leads to permanent tendon damage; evidence-after the patient lifts the arm no tendon damage occurs). While the ViolEx Model suggests that cognitive immunization strategies are responsible for the maintenance of dysfunctional expectations, we suggest that such phenomenon can also be understood from a Bayesian Brain perspective, according to which the level of precision of the priors (i.e., expectations) is the determinant factor accounting for the extent of priors' updating (i.e., we merge the two frameworks, suggesting that highly precise prior can lead to cognitive immunization responses). Importantly, this Perspective translates the theory behind these two frameworks into clinical suggestions. Precisely, it is argued that different strategies should be implemented when treating MSK pain patients, depending on the nature of their expectations (i.e., positive or negative and the level of their precision).

Patients' prior perceptions and expectations of the Enhanced Transtheoretical Model Intervention for chronic low back pain: A qualitative study

BACKGROUND

The Enhanced Transtheoretical Model Intervention (ETMI) is an approach for treating chronic low back pain (CLBP), which demonstrated clinical and cost-effectiveness outcomes. ETMI highlights reassurance, return to normal activities and encouragement of recreational physical activity. In order to optimally implement ETMI, it is important to gain an understanding of the expectations and perceptions of patients before they engage with the intervention.

OBJECTIVES

To explore CLBP patients' perceptions and expectations of the ETMI method prior to their first consultation with physiotherapist.

METHODS

Qualitative semi-structured interviews were conducted with 30 CLBP patients. The interviews were audio-recorded, transcribed, coded, and analysed thematically. Patients were first asked about their expectations of treatment, then they were asked to comment on the ETMI method.

RESULTS

Three main themes emerged from the interviews: (1) Patient's perceptions of LBP; (2) patient's expectations from current physiotherapy and (3) Patient's expectations from ETMI method. The patients' perceptions of back pain centred on biomechanical causal factors, a desire for diagnostic tests and beliefs that rest cures the pain. Their expectations from current physiotherapy included pain reduction, passive treatment, a structured exercise program and clear information about LBP. In reference to the ETMI method, patients expected pain reduction, practical tools to self-manage, and a combination of ETMI with passive treatment.

CONCLUSION

addressing issues around patient's perceptions and expectations of current physiotherapy and of the ETMI method, prior to their first consultation with physiotherapist, could be beneficial for understanding how to improve the ETMI implementation in the health care system.
