Occupational rehabilitation programs for musculoskeletal pain and common mental health disorders: study protocol of a randomized controlled trial

BackgroundLong-term sick leave has considerably negative impact on the individual and society. Hence, the need to identify effective occupational rehabilitation programs is pressing. In Norway, group based occupational rehabilitation programs merging patients with different diagnoses have existed for many years, but no rigorous evaluation has been performed. The described randomized controlled trial aims primarily to compare two structured multicomponent inpatient rehabilitation programs, differing in length and content, with a comparative cognitive intervention. Secondarily the two inpatient programs will be compared with each other, and with a usual care reference group.Methods/designThe study is designed as a randomized controlled trial with parallel groups. The Social Security Office performs monthly extractions of sick listed individuals aged 18–60 years, on sick leave 2–12 months, with sick leave status 50% - 100% due to musculoskeletal, mental or unspecific disorders. Sick-listed persons are randomized twice: 1) to receive one of two invitations to participate in the study or not receive an invitation, where the latter “untouched” control group will be monitored for future sick leave in the National Social Security Register, and 2) after inclusion, to a Long or Short inpatient multicomponent rehabilitation program (depending on which invitation was sent) or an outpatient cognitive behavioral therapy group comparative program. The Long program consists of 3 ½ weeks with full rehabilitation days. The Short program consists of 4 + 4 full days, separated by two weeks, in which a workplace visit will be performed if desirable. Three areas of rehabilitation are targeted: mental training, physical training and work-related problem solving. The primary outcome is number of sick leave days. Secondary outcomes include time until full sustainable return to work, health related quality of life, health related behavior, functional status, somatic and mental health, and perceptions of work. In addition, health economic evaluation will be performed, and the implementation of the interventions, expectations and experiences of users and service providers will be investigated with different qualitative methods.Trial registrationClinicalTrials.gov: NCT01926574.

Sick-listed persons’ experiences with taking part in an in-patient occupational rehabilitation program based on Acceptance and Commitment Therapy: a qualitative focus group interview study

BackgroundOccupational medicine has shifted emphasis from disease treatment to disability rehabilitation and management. Hence, newly developed occupational rehabilitation programs are often generic and multicomponent, aiming to influence the sick-listed persons’ perception on return to work, and thereby support the return to work process. The aim of this study was to explore sick-listed persons’ experiences with taking part in an in-patient occupational rehabilitation program based on Acceptance and Commitment Therapy.MethodsTwenty-nine adults on sickness benefit or work assessment allowance due to musculoskeletal and/or common mental health disorders participated in this study. They were interviewed in focus groups at the beginning and at the end of a 3.5 week inpatient group-based occupational rehabilitation program in Central Norway. Key elements in the program were Acceptance and Commitment Therapy (ACT), physical exercise and creating a work-participation plan. The program was mainly group-based including participants with different diagnoses. Data was analyzed according to a phenomenological approach.ResultsAt the start of the program most participants expressed frustration regarding being sick-listed, external anticipations as well as hindrances towards returning to work, and described hope that the program would provide them with the skills and techniques necessary to cope with health problems and being able to return to work. At the end of the program the participants described that they had embarked upon a long process of increased awareness. This process encompassed four areas; an increased awareness of what was important in life, realizing the strain from external expectations and demands, a need to balance different aspects of life, and return to work as part of a long and complex process.ConclusionsThe occupational rehabilitation program induced a perceived meaningful reorientation encompassing several aspects of life. However, the return to work process was described as diffuse and uncertain for most participants. The providers of occupational rehabilitation program should balance this reorientation with specific steps towards return to work. Effect studies and long-term qualitative studies evaluating how this affects long-term work- and health outcomes are underway.

Evidence for a general stiffening motor control pattern in neck pain: a cross sectional study

BackgroundNeck pain is associated with several alterations in neck motion and motor control. Previous studies have investigated single constructs of neck motor control, while few have applied a comprehensive set of tests to investigate cervical motor control. This comparative cross- sectional study aimed to investigate different motor control constructs in neck pain patients and healthy controls.MethodsA total of 166 subjects participated in the study, 91 healthy controls (HC) and 75 neck pain patients (NP) with long-lasting moderate to severe neck pain. Neck flexibility, proprioception, head steadiness, trajectory movement control, and postural sway were assessed using a 3D motion tracking system (Liberty). The different constructs of neck motion and motor control were based on tests used in previous studies.ResultsNeck flexibility was lower in NP compared to HC, indicated by reduced cervical ROM and conjunct motion. Movement velocity was slower in NP compared to HC. Tests of head steadiness showed a stiffer movement pattern in NP compared to HC, indicated by lower head angular velocity. NP patients departed less from a predictable trajectory movement pattern (figure of eight) compared to healthy controls, but there was no difference for unpredictable movement patterns (the Fly test). No differences were found for postural sway in standing with eyes open and eyes closed. However, NP patients had significantly larger postural sway when standing on a balance pad. Proprioception did not differ between the groups. Largest effect sizes (ES) were found for neck flexibility (ES range: 0.2- 0.8) and head steadiness (ES range: 1.3- 2.0). Neck flexibility was the only construct that showed a significant association with current neck pain, while peak velocity was the only variable that showed a significant association with kinesiophobia.ConclusionsNP patients showed an overall stiffer and more rigid neck motor control pattern compared to HC, indicated by lower neck flexibility, slower movement velocity, increased head steadiness and more rigid trajectory head motion patterns. Only neck flexibility showed a significant association with clinical features in NP patients.

Physical examination tests of the shoulder: a systematic review and meta-analysis of diagnostic test performance

BackgroundPhysical examination tests of the shoulder (PETS) are clinical examination maneuvers designed to aid the assessment of shoulder complaints. Despite more than 180 PETS described in the literature, evidence of their validity and usefulness in diagnosing the shoulder is questioned.MethodsThis meta-analysis aims to use diagnostic odds ratio (DOR) to evaluate how much PETS shift overall probability and to rank the test performance of single PETS in order to aid the clinician’s choice of which tests to use. This study adheres to the principles outlined in the Cochrane guidelines and the PRISMA statement. A fixed effect model was used to assess the overall diagnostic validity of PETS by pooling DOR for different PETS with similar biomechanical rationale when possible. Single PETS were assessed and ranked by DOR. Clinical performance was assessed by sensitivity, specificity, accuracy and likelihood ratio.ResultsSix thousand nine-hundred abstracts and 202 full-text articles were assessed for eligibility; 20 articles were eligible and data from 11 articles could be included in the meta-analysis. All PETS for SLAP (superior labral anterior posterior) lesions pooled gave a DOR of 1.38 [1.13, 1.69]. The Supraspinatus test for any full thickness rotator cuff tear obtained the highest DOR of 9.24 (sensitivity was 0.74, specificity 0.77). Compression-Rotation test obtained the highest DOR (6.36) among single PETS for SLAP lesions (sensitivity 0.43, specificity 0.89) and Hawkins test obtained the highest DOR (2.86) for impingement syndrome (sensitivity 0.58, specificity 0.67). No single PETS showed superior clinical test performance.ConclusionsThe clinical performance of single PETS is limited. However, when the different PETS for SLAP lesions were pooled, we found a statistical significant change in post-test probability indicating an overall statistical validity. We suggest that clinicians choose their PETS among those with the highest pooled DOR and to assess validity to their own specific clinical settings, review the inclusion criteria of the included primary studies. We further propose that future studies on the validity of PETS use randomized research designs rather than the accuracy design relying less on well-established gold standard reference tests and efficient treatment options.

Cognitive Interventions and Nutritional Supplements (The CINS Trial): A Randomized Controlled, Multicenter Trial Comparing a Brief Intervention with Additional Cognitive Behavioral Therapy, Seal Oil, and Soy Oil for Sick-Listed Low Back Pain Patients

Study Design. A randomized controlled trial. Objective. The aim of this study was to evaluate whether a tailored and manualized cognitive behavior therapy (CBT) or nutritional supplements of seal oil and soy oil had any additional benefits over a brief cognitive intervention (BI) on return to work (RTW). Summary of Background Data. Brief intervention programs are clinically beneficial and cost-effective for patients with low back pain (LBP). CBT is recommended for LBP, but evidence on RTW is lacking. Seal oil has previously been shown to have a possible effect on muscle pain, but no randomized controlled trials have so far been carried out in LBP patients. Methods. Four hundred thirteen adults aged 18 to 60 years were included. Participants were sick-listed 2 to 10 months due to LBP. Main outcome was objectively ascertained work participation at 12-month follow-up. Participants were randomly assigned to BI (n = 100), BI and CBT (n = 103), BI and seal oil (n = 105), or BI and soy oil (n = 105). BI is a two-session cognitive, clinical examination program followed by two booster sessions, while the CBT program is a tailored, individual, seven-session manual-based treatment. Results. At 12-month follow-up, 60% of the participants in the BI group, 50% in the BI and CBT group, 51% in the BI and seal oil group, and 53% in the BI and soy oil group showed reduced sick leave from baseline, and had either partly or fully RTW. The differences between the groups were not statistically significant (&khgr;2 = 2.54, P = 0.47). There were no significant differences between the treatment groups at any of the other follow-up assessments either, except for a significantly lower sick leave rate in the BI group than the other groups during the first 3 months of follow-up (&khgr;2 = 9.50, P = 0.02). Conclusion. CBT and seal oil had no additional benefits over a brief cognitive intervention on sick leave. The brief cognitive intervention alone was superior in facilitating a fast RTW. Level of Evidence: 2

Transdiagnostic group-based occupational rehabilitation for participants with chronic pain, chronic fatigue and common mental disorders. A feasibility study

Abstract Purpose: The aim was to investigate the feasibility of introducing a novel transdiagnostic occupational rehabilitation program delivered in groups mixing participants with chronic pain, chronic fatigue and common mental disorders. Materials and methods: Observational data on group climate and individual participation were triangulated with qualitative data from focus group interviews on the participants’ experiences with transdiagnostic groups. Results: The study included 222 participants receiving a temporary work disability benefit. Self-reported chronic pain (75%), chronic fatigue (79%), and mental distress (62%) were prevalent and the majority reported overlapping conditions (78%). Program completion among participants was high (96%). Those completing participated actively (95%) in the program. Overall group climate was stable with moderately high engagement. Participants with clinically confirmed mental disorders (22%) showed similar outcomes. Self-reported problems with “working in a group” prior to rehabilitation were not associated with how participants experienced group climate. Qualitative data supported the findings of positive participant experiences with transdiagnostic group settings. Conclusions: Transdiagnostic groups showed high participation rates, moderately high group engagement across symptom profiles and positive participant experiences. Implementing transdiagnostic occupational rehabilitation in groups mixing participants with chronic pain, chronic fatigue and common mental disorders was feasible and acceptable to participants. Implications for rehabilitation Most research has been done on disorder-specific occupational rehabilitation programs, but emerging evidence supports a more generic approach. Transdiagnostic therapies, such as Acceptance and Commitment Therapy (ACT), have shown promising results for both somatic and mental disorders. The feasibility of implementing transdiagnostic rehabilitation groups, their acceptability to participants and the demand for such groups has not been established. This study indicates that it is feasible to introduce a novel transdiagnostic group-based occupational rehabilitation program for mixed groups of sick-listed participants with chronic pain, chronic fatigue and/or common mental disorders.

The feasibility of occupational rehabilitation in transdiagnostic groups for participants with chronic pain, chronic fatigue and common mental disorders

SamenvattingMost occupational rehabilitation programmes target specific disorders. Crossover between programmes for mental and somatic disorders has been discussed and it has been pointed out that interventions may be applicable across different diagnostic categories. This study aimed to investigate the feasibility of introducing a novel transdiagnostic occupational rehabilitation programme that was delivered in groups mixing participants with chronic pain, chronic fatigue and common mental disorders.

The acceptance and commitment therapy model in occupational rehabilitation of musculoskeletal and common mental disorders: a qualitative focus group study

Abstract Aims: The aim of this study was to examine whether and how intended processes of behavioural change were reflected in participants’ experiences after an inpatient occupational rehabilitation programme. The programme was transdiagnostic, lasted 3½ weeks and was based on the acceptance and commitment therapy model. Methods: Twenty-two participants (17 women and 5 men) took part in five qualitative focus group interviews after the programme. Analysis was data-driven, categorising participants’ experiences using an initial explorative phenomenological approach. The emerging data-driven categories were re-contextualised within the theoretical framework of the therapy model. Results: The participants referred to experiences within all three intended domains of the model (openness, awareness, and engagement). Our results indicate that the transdiagnostic approach may have facilitated openness, while the attainment of flexible self-awareness was less evident. Participants expressed engagement and behavioural changes linked to personal values, but did not mention actions leading to imminent return to work. Conclusions: The results imply that for implementation in occupational rehabilitation, further development of this model is needed specifically regarding processes related to self-awareness and committed action towards work. These findings are relevant for the interpretation of results from randomised clinical trials on acceptance and commitment therapy in occupational rehabilitation. Implications for rehabilitation Acceptance and commitment therapy seems to be a feasible component in an occupational rehabilitation programme for persons with different diagnoses. A transdiagnostic approach mixing musculoskeletal pain disorders and common mental disorders in the same rehabilitation programme seems to facilitate the process of openness and acceptance. There is a need to further develop and operationalise some of the processes in Acceptance and commitment therapy to accommodate the approach to the occupational rehabilitation context.
