Prediction of function in daily life following multidisciplinary rehabilitation for individuals with chronic musculoskeletal pain; a prospective study

Breaking Barriers: Artificial Intelligence Interpreting the Interplay between Mental Illness and Pain as Defined by the International Association for the Study of Pain

Low back pain is one of the main causes of motor disabilities and psychological stress, with the painful process encompassing sensory and affective components. Noxious stimuli originate on the periphery; however, the stimuli are recombined in the brain and therefore processed differently due to the emotional environment. To better understand this process, our objective was to develop a mathematical representation of the International Association for the Study of Pain (IASP) model of pain, covering the multidimensional representation of this phenomenon. Data from the Oswestry disability index; the short form of the depression, anxiety, and stress scale; and pain catastrophizing daily questionnaires were collected through online completion, available from 8 June 2022, to 8 April 2023 (1021 cases). Using the information collected, an artificial neural network structure was trained (based on anomaly detection methods) to identify the patterns that emerge from the relationship between the variables. The developed model proved to be robust and able to show the patterns and the relationship between the variables, and it allowed for differentiating the groups with altered patterns in the context of low back pain. The distinct groups all behave according to the main finding that psychological and pain events are directly associated. We conclude that our proposal is effective as it is able to test and confirm the definition of the IASP for the study of pain. Here we show that the fiscal and mental dimensions of pain are directly associated, meaning that mental illness can be an enhancer of pain episodes and functionality.

Can Baseline Characteristics Predict Successful Outcomes after Individual, Physiotherapist-Led Rehabilitation in Patients with Chronic Musculoskeletal Pain?

Background

No strong and consistent variables to predict outcome after pain rehabilitation have been reported in patients with chronic musculoskeletal pain. The aim of the present study was to clarify if baseline variables could predict successful outcome after a unique, individualized, physiotherapist-led rehabilitation of nine sessions.

Methods

In 274 individuals with severe chronic musculoskeletal pain, the risk ratio (RR) and 95% confidence intervals (CIs) were estimated for potentially predictive baseline variables on successful outcomes of pain management, overall health, and pain rating.

Results

Statistically significant results show that patients rating moderate or severe baseline pain were in both cases 14% less likely to improve pain management compared to patients rating mild baseline pain (RR = 0.86; 95% CI 0.77-0.97, RR = 0.86; 95% CI 0.74-1.00). Patients with the shortest pain duration were 1.61 times more likely to improve overall health (RR = 1.61; 95% CI 1.13-2.29) compared to patients reporting the longest pain duration (>5 years). Patients reporting anxiety/depression or severe pain were in both cases 1.48 times more likely to improve overall health compared to better baseline presentations (RR = 1.48; 95% CI 1.16-1.88, RR = 1.48; 95% CI 1.03-2.15). Patients with regional/generalized pain were 36% less likely to rate pain reduction (RR = 0.64; 95% CI 0.41-1.00) compared to patients rating localized baseline pain. Of 17 potentially predictive baseline variables, four reached statistical significance for at least one of the three outcomes; although none of them for all three outcomes.

Conclusions

Of 17 potentially predictive baseline variables, mild pain ratings, short pain duration, and localized baseline pain were statistically significantly associated with improvements after individual, physiotherapist-led rehabilitation for patients with chronic musculoskeletal pain. This suggests that this type of rehabilitation probably should be offered early in the pain process. Reporting anxiety/depression or severe pain at the baseline did not hinder the improvements of overall health.

Predicting treatment adherence and outcome to outpatient multimodal rehabilitation in chronic low back pain

BACKGROUND

There is a growing need to identify patient pre-treatment characteristics that could predict adherence and outcome following specific interventions.

OBJECTIVE

To identify predictors of adherence and outcome to outpatient multimodal rehabilitation in chronic low back pain (CLBP).

METHODS

A total of 273 CLBP patients participated in an exercise-based rehabilitation program. Patients who completed ⩾ 70% of the treatment course were classified as adherent. Patients showing a post-treatment reduction of ⩾ 30% in Oswestry Disability Index (ODI) and Visual Analogue Scale (VAS) back pain intensity scores were assigned to the favorable outcome group.

RESULTS

Multivariate logistic regression revealed that higher age, higher ability to perform low-load activities, and higher degrees of kinesiophobia increased the odds to complete the rehabilitation program. By contrast, lower levels of education and back pain unrelated to poor posture increased the odds for non-adherence. Furthermore, a favorable outcome was predicted in case the cause for LBP was known, shorter symptom duration, no pain in the lower legs, no difficulties falling asleep, and short-term work absenteeism.

CONCLUSIONS

Assessment and consideration of patient pre-treatment characteristics is of great importance as they may enable therapists to identify patients with a good prognosis or at risk for non-responding to outpatient multimodal rehabilitation.

Prognostic Factors for Physical Functioning After Multidisciplinary Rehabilitation in Patients With Chronic Musculoskeletal Pain: A Systematic Review and Meta-Analysis

OBJECTIVES

This systematic review aimed to identify and evaluate prognostic factors for long-term (≥6 mo) physical functioning in patients with chronic musculoskeletal pain following multidisciplinary rehabilitation (MDR).

MATERIALS AND METHODS

Electronic searches conducted in MEDLINE, PsycINFO, EMBASE, CINAHL, Web of Science, and Cochrane CENTRAL revealed 25 original research reports, published 1983-2016, (n=9436). Potential prognostic factors relating to initial pain and physical and psychological functioning were synthesized qualitatively and quantitatively in random effects meta-analyses. The level of evidence (LoE) was evaluated with Grading of Recommendations Assessment, Development and Evaluation (GRADE).

RESULTS

Pain-related factors (intensity and chronicity) were not associated with function/disability at long-term follow-up, odds ratio (OR)=0.84; 95% confidence interval (CI), 0.65-1.07 and OR=0.97; 95% CI, 0.93-1.00, respectively (moderate LoE). A better function at follow-up was predicted by Physical factors; higher levels of initial self-reported functioning, OR=1.07; 95% CI, 1.02-1.13 (low LoE), and Psychological factors; low initial levels of emotional distress, OR=0.77; 95% CI, 0.65-0.92, low levels of cognitive and behavioral risk factors, OR=0.85; 95% CI, 0.77-0.93 and high levels of protective cognitive and behavioral factors, OR=1.49; 95% CI, 1.17-1.90 (moderate LoE).

DISCUSSION

While pain intensity and long-term chronicity did not predict physical functioning in chronic pain patients after MDR, poor pretreatment physical and psychological functioning influenced the prognosis negatively. Thus, treatment should further target and optimize these modifiable factors and an increased focus on positive, psychological protective factors may perhaps provide an opening for yet untapped clinical gains.

Rehabilitation and management outcomes of musculoskeletal injuries in a major referral hospital in Ghana

Background

The devastating impact of musculoskeletal injury (MSI) on human lives, the economy, and health services cannot be overemphasised. This has ignited discussion at international fora, as countries have been exhorted to prioritise management of MSI in order to maintain a healthy society. In the Ghanaian context, the knowledge base management of MSI is very low, which has provided the impetus to explore the management of MSI and the rehabilitation systems at a tertiary hospital in Ghana.

Methods

The study was a retrospective cross-sectional study, using the consecutive sampling method to recruit patients who were discharged after admission at the accident and emergency unit, as well as patients undergoing orthopaedic review, at the St. Joseph’s Orthopaedic Hospital in Koforidua over a six-month period.

Results

A total of 269 musculoskeletal injury patients were recruited for the study. Half of the participants (51%) had had surgery in addition to pain medication. The overall mean recovery days were 26.81 ± 33.94 days, and the average disability days spent in the hospital were estimated at 16.54 ± 27.97 days. Individuals reported financial constraints as a major challenge to their full participation in rehabilitation.

Conclusion

The findings of this study have implications for policymaking in Ghana. Particularly, the need to improve health facilities to enable MSI patients to seek treatment is highlighted. Also, the need to train health professionals who will be able to administer appropriate medication for MSI patients is discussed extensively.

Evaluation of daily outpatient multidisciplinary rehabilitative treatment of patients with musculoskeletal, neurological and traumatic disorders in a municipality outpatient setting

BACKGROUND AND OBJECTIVE

Musculoskeletal, neurological, and traumatic injuries are a considerably increasing problem. There is a lack of studies evaluating the results of outpatient rehabilitative treatment of patients with the abovementioned diseases. The aim of this study was to determine the effectiveness of daily outpatient multidisciplinary rehabilitation.

MATERIALS AND METHODS

This observational study enrolled 223 adult people undergoing outpatient rehabilitation performed in a municipality outpatient clinic during 14 days. The functional assessment of disability was performed by using the Barthel index (BI), functional performance was estimated by the modified Keitel functional test (MKFT), and pain perception was evaluated by the visual analogue scale (VAS). The mean scores of the tests were compared before and after outpatient multidisciplinary rehabilitation.

RESULTS

Significantly reduced disability and pain perception as well as increased functional performance were documented after outpatient rehabilitation. The mean scores of BI, MKFT, and VAS before and after rehabilitation did not differ significantly among patients ranked to each cluster of diseases. Increased functional performance of patients had a moderate-to-weak association with decreased disability and pain perception. The positive changes in health status considering disability, functional performance, and pain perception were documented after 14-day rehabilitation.

CONCLUSIONS

Multidisciplinary outpatient rehabilitation can be considered as effective treatment. However, it is necessary to implement specific, well-adapted consuming assessment instruments in order to evaluate the outcomes of daily multidisciplinary outpatient rehabilitative treatment.

Disability Pensions Among Young Adults in Vocational Rehabilitation

OBJECTIVES

Lack of work-participation and early disability pensions (DP's) among young adults are increasing public health problems in most western European countries. The present study investigated determinants of early DP in young adults in vocational rehabilitation.

METHODS

Data from 928 young adults (aged 18-40 years) attending a vocational rehabilitation program was linked to DP's recorded in the Norwegian Labor and Welfare Organization registries (1992-2010) and later compared to a group of 65 employees (workers). We used logistic regression to estimate the odds ratio for entitlement to DP following rehabilitation, adjusting for socio-demographical, psychosocial and health-behavior factors.

RESULTS

Significant differences in socio-demographical, psychosocial and health-behavior factors were found between the rehabilitation group and workers. A total of 60 individuals (6.5%) were granted a DP during follow-up. Increase in age, teenage parenthood, single status, as well as low education level and not being employed were found to be the strongest independent determinants of DP.

CONCLUSION

Poor social relations (being lone), early childbearing and weak connection to working life contributed to increase in risk of DP's among young adults in vocational rehabilitation, also after adjusting for education level. These findings are important in the prevention of early disability retirements among young adults and should be considered in the development of targeted interventions aimed at individuals particularly at risk of not being integrated into future work lives.

Prognostic indicators of social outcomes in persons who sustained an injury in a road traffic crash

INTRODUCTION

There is a lack of longitudinal studies with adequate sample size and follow-up period which have objectively assessed social outcomes among those with mild or moderate musculoskeletal injury or that are not limited to hospital inpatients. We aimed to address this gap by prospectively assessing the potential predictors of return to pre-injury work and daily activities.

METHODS

Persons with mild/moderate musculoskeletal injuries from a vehicle-related crash were surveyed within the first 3 months after the crash (baseline; n=364), and at 12 (n=284) and 24 months (n=252). Participants self-reported return to work, and whether it was return to full or modified duties at work. Analyses were restricted to 170 participants who reported being in pre-injury paid work and had provided information at either 12 months only or at both 12 and 24 months. Return to usual activities was assessed using the European Quality of Life-5 Dimensions (EQ-5D) scale 'Usual Activities' dimension.

RESULTS

Twenty-four months after injury 82% (n=121) had returned to work. After multivariable adjustment, not being admitted to hospital was associated with 44% higher likelihood of returning to work at 24 months. Not having any pre-injury chronic illness was associated with returning to work after 24 months, multivariable-adjusted risk ratio (RR), 1.21 (95% confidence intervals, CI: 1.02-1.45). Each 1-SD increase in Medical Outcomes Survey Short Form-12 Mental Component Summary (SF-12 MCS) score at baseline was associated with returning to work at 24 months RR 1.13 (95% CI: 1.02-1.25). Younger age, higher SF-12 physical component summary (PCS), and EQ-5D visual analogue scale (VAS) scores were mutually independent predictors of returning to usual activities 24 months later.

CONCLUSION

A range of bio-psychosocial factors, particularly quality of life measures, independently predicted social outcomes including return to work and return to usual daily activities. These determinants could be measured early in the recovery process and be potentially amenable to intervention.

Several submaximal exercise tests are reliable, valid and acceptable in people with chronic pain, fibromyalgia or chronic fatigue: a systematic review

QUESTION

Are submaximal and maximal exercise tests reliable, valid and acceptable in people with chronic pain, fibromyalgia and fatigue disorders?

DESIGN

Systematic review of studies of the psychometric properties of exercise tests.

PARTICIPANTS

People older than 18 years with chronic pain, fibromyalgia and chronic fatigue disorders.

INTERVENTION

Studies of the measurement properties of tests of physical capacity in people with chronic pain, fibromyalgia or chronic fatigue disorders were included.

OUTCOME MEASURES

Studies were required to report: reliability coefficients (intraclass correlation coefficient, alpha reliability coefficient, limits of agreements and Bland-Altman plots); validity coefficients (intraclass correlation coefficient, Spearman's correlation, Kendal T coefficient, Pearson's correlation); or dropout rates.

RESULTS

Fourteen studies were eligible: none had low risk of bias, 10 had unclear risk of bias and four had high risk of bias. The included studies evaluated: Åstrand test; modified Åstrand test; Lean body mass-based Åstrand test; submaximal bicycle ergometer test following another protocol other than Åstrand test; 2-km walk test; 5-minute, 6-minute and 10-minute walk tests; shuttle walk test; and modified symptom-limited Bruce treadmill test. None of the studies assessed maximal exercise tests. Where they had been tested, reliability and validity were generally high. Dropout rates were generally acceptable. The 2-km walk test was not recommended in fibromyalgia.

CONCLUSION

Moderate evidence was found for reliability, validity and acceptability of submaximal exercise tests in patients with chronic pain, fibromyalgia or chronic fatigue. There is no evidence about maximal exercise tests in patients with chronic pain, fibromyalgia and chronic fatigue.

Coping and disability: evidence from a developing country

AIM

In view of the increasing burden of musculoskeletal-related disability, the growing number of older persons and the scarcity of research on musculoskeletal conditions in the Eastern Mediterranean region, coping with musculoskeletal problems deserves special attention. This paper examines how good coping links to musculoskeletal-related disability among Lebanese citizens aged 15 years and older.

METHODS

The sample included 200 people living in southern Lebanon and who participated in the Community Oriented Program for Control of Rheumatic Diseases (COPCORD) survey. Disability and coping were assessed using self-reported questions. Covariates included demographics, musculoskeletal pain variables, and body mass index (BMI).

RESULTS

Around one-third of the sample had lifetime functional disability due to musculoskeletal problems and 62% were coping well with their problems. Adjusted data showed that the odds of musculoskeletal-related disability among individuals who were not coping well was 2.35 times the odds of disability among individuals who were coping well with 95% CI = 1.10-5.02.

CONCLUSION

This study provides evidence of the importance of complementing pharmacological treatment with a cognitive-behavioral approach for management of musculoskeletal problems.

Depression and age as predictors of patient-reported outcome in a multidisciplinary rehabilitation programme for chronic musculoskeletal pain

BACKGROUND

The recommended treatment for chronic musculoskeletal pain is multidisciplinary, with a cognitive approach. The aim of this study was to investigate health-related quality of life (HRQoL) outcome after a multidisciplinary treatment with a cognitive approach.

METHODS

A total of 131 subjects who participated in a multidisciplinary rehabilitation programme (2005-2008) were studied at baseline and after six months, using the Short Form Short Form 36-item Health Survey questionnaire (SF-36) as primary outcome (HRQoL), and the Hospital Anxiety and Depression Scale (HAD) and pain as secondary outcomes and possible baseline predictors for HRQoL.

RESULTS

Complete data were available for 97 subjects (85 women, mean age [SD] 44.6 [9.7] years). The SF-36 subscales physical function (PF), general health (GH), vitality (VT), social function (SF) and mental health (MH), the visual analogue scale for pain and the HAD improved significantly (p < 0.05) at follow-up compared with baseline. A pre-treatment probable depression (HAD score ≥11) was associated with a favourable outcome of the SF-36 subscales PF (odds ratio [OR] 5.6; p = 0.01), VT (OR 4.3; p = 0.02) and MH (OR 3.6; p = 0.02). A probable anxiety (HAD score ≥11) was associated with a favourable outcome of PF (OR 2.6; p = 0.05). There was an even stronger association for younger subjects (20-45 years), with probable depression scores at baseline and a favourable HRQoL outcome at follow up.

CONCLUSION

This multidisciplinary rehabilitation programme, using a non-pharmacological cognitive approach, seemed to yield a better outcome concerning HRQoL measures in younger subjects with higher depression scores at baseline. This information is important for clinics when tailoring a multidisciplinary rehabilitation programme for patients with musculoskeletal chronic pain.

Life dissatisfaction in the pre-operative and early recovery phase predicts low functional ability and coping among post-operative patients with lumbar spinal stenosis: a 2-year prospective study

PURPOSE

We examined the significance of life dissatisfaction in pre-operative and early recovery phases with respect to functional ability, pain and coping on 2-year follow-up of patients with lumbar spinal stenosis (LSS).

METHODS

Patients (n=90, mean age, 62 years, men 40%) with symptomatic LSS underwent decompressive surgery. Data collection took place with the same set of questionnaires before surgery and 3 months, 6 months and 2 years postoperatively. Life dissatisfaction was assessed with the four-item life satisfaction (LS) scale. In addition, a life dissatisfaction burden, comprising the sum of preoperative, 3-month and 6-month LS scores, was calculated. Physical functioning (Oswestry disability index), pain (VAS and pain drawing) and coping (sense of coherence, SOC) were assessed. Logistic regression analysis was used to examine life dissatisfaction as a predictor of the 2-year functional ability, pain and coping (SOC).

RESULTS

In these analyses, pain was not predicted by either pre-operative life dissatisfaction or life dissatisfaction burden. However, both disability and poor coping on 2-year follow-up were independently associated with both pre-operative and early recovery phase life dissatisfaction.

CONCLUSIONS

Our results show the importance of both pre-operative and early post-operative well-being regarding subsequent functioning. Thus, monitoring of the subjective well-being throughout the pre-operative and post-operative period may indicate those patients at risk of poorer post-operative recovery.

Perception of multimodal cognitive treatment for people with chronic widespread pain--changing one's life plan

PURPOSE

The aim of this study was to gain a deeper understanding of chronic widespread pain patients' perception of a multimodal treatment with a cognitive approach.

METHODS

A reformulated grounded theory study based on interviews with 16 participants in the programme was conducted at the end of a 6-month treatment period.

RESULTS

The result describes a conceptual model of the informants' perception of the treatment. The core category 'changing one's life plan' comprised of three categories: 'changing one's perception of life', 'depending on support' and 'managing one's life'. Changing one's perception of life could be deep and overwhelming 'overall life changes' or more superficial 'life adjustments'. Support by health professionals and the patient group were of importance. At the end of the rehabilitation program managing one's life was perceived as either 'reorientation' or 'stagnation'. The informants who experienced overall life changes achieved reorientation with support by others, while those who experienced life adjustments did not change their way of managing one's life to any great extent.

CONCLUSION

The core category changing one's life plan included the categories; changing one's perception of life, depending on support and managing one's life. Informants experiencing overall life changes were more likely to achieve reorientation than those who experienced life adjustments.
