OBJECTIVE To compare the effects of an interdisciplinary pain management programme with those of standard in-patient rehabilitation by comprehensive biopsychosocial self--assessment. METHODS In this naturalistic prospective controlled cohort study, 164 chronic pain patients who participated in the interdisciplinary pain programme and 143 who underwent standard rehabilitation were assessed using standardized instruments. Effect differences were compared bivariately and analysed by multivariate logistic regression to control for baseline differences in the outcome variables and confounders. RESULTS On entry into the clinic, the interdisciplinary pain programme patients were younger and showed significantly worse mental and psychosocial health than the standard rehabilitation patients. At discharge, the interdisciplinary pain programme patients reported greater improvement on pain (multivariate p = 0.034), social functioning (bivariate p = 0.009), and in trend in catastrophizing and ability to decrease pain. At the 6-month follow-up, the effects experienced by the standard rehabilitation group were higher on physical functioning, social functioning, anxiety, and life control (multivariate p = 0.013-0.050). CONCLUSION Intensive interdisciplinary rehabilitation with more behavioural therapies was accompanied by a greater improvement in patients who were severely affected by pain, compared with standard rehabilitation by the end of the stay, but not in the mid-term. Highly resource-consuming patients may benefit from subsequent, individually tailored outpatient care.

BackgroundPatients with non-specific back pain are not a homogeneous group but heterogeneous with regard to their bio-psycho-social impairments. This study examined a sample of 173 highly disabled patients with chronic back pain to find out how the three subgroups based on the Multidimensional Pain Inventory (MPI) differed in their response to an inpatient pain management program.MethodsSubgroup classification was conducted by cluster analysis using MPI subscale scores at entry into the program. At program entry and at discharge after four weeks, participants completed the MPI, the MOS Short Form-36 (SF-36), the Hospital Anxiety and Depression Scale (HADS), and the Coping Strategies Questionnaire (CSQ). Pairwise analyses of the score changes of the mentioned outcomes of the three MPI subgroups were performed using the Mann-Whitney-U-test for significance.ResultsCluster analysis identified three MPI subgroups in this highly disabled sample: a dysfunctional, interpersonally distressed and an adaptive copers subgroup. The dysfunctional subgroup (29% of the sample) showed the highest level of depression in SF-36 mental health (33.4 ± 13.9), the interpersonally distressed subgroup (35% of the sample) a modest level of depression (46.8 ± 20.4), and the adaptive copers subgroup (32% of the sample) the lowest level of depression (57.8 ± 19.1). Significant differences in pain reduction and improvement of mental health and coping were observed across the three MPI subgroups, i.e. the effect sizes for MPI pain reduction were: 0.84 (0.44 - 1.24) for the dysfunctional subgroup, 1.22 (0.86 - 1.58) for the adaptive copers subgroup, and 0.53 (0.24 - 0.81) for the interpersonally distressed subgroup (p = 0.006 for pairwise comparison). Significant score changes between subgroups concerning activities and physical functioning could not be identified.ConclusionsMPI subgroup classification showed significant differences in score changes for pain, mental health and coping. These findings underscore the importance of assessing individual differences to understand how patients adjust to chronic back pain.

BackgroundAccording to Antonovsky’s salutogenic concept, a strong sense of coherence is associated with physical and psychological health. The goal of this study was to analyze the association of Antonovsky’s sense of coherence with physical and psychosocial health components in patients with hip and knee osteoarthritis before and after in- and outpatient rehabilitation.MethodsProspective cohort study with 335 patients, 136 (41%) with hip and 199 (59%) with knee osteoarthritis. The outcome was measured by Short Form-36 (SF-36), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and the Sense of Coherence (SOC-13). Baseline scores of the SF-36 and WOMAC scales and the observed effect sizes after rehabilitation were correlated with the baseline SOC-13. These correlations of the SF-36 scales were compared to the Factor Score Coefficients for the Mental Component Summary of SF-36, which quantify the factor load on the psychosocial dimension. Predictive impact of the baseline SOC-13 for the SF-36 and WOMAC scales (baseline scores and effect sizes) was then determined by multivariate linear regression controlled for possible confounders.ResultsAt baseline, the SOC-13 correlated with the WOMAC scores between r = 0.18 (stiffness) and r = 0.25 (pain) and with the SF-36 scores between r = 0.10 (physical functioning) and r = 0.53 (mental health). The correlation of these SF-36 correlation coefficients to the Factor Score Coefficient of the SF-36 Mental Component Summary was r = 0.95. The correlations for the effect sizes (baseline → discharge) with the baseline SOC-13 global score were all negative and varied between r = 0.00 (physical functioning) and r = −0.19 (social functioning). In the multivariate linear regression model, the explained variance of the SF-36 scores by the baseline SOC-13 increased continuously from physical to psychosocial health dimensions (from 12.9% to 29.8%). This gradient was consistently observed for both the baseline scores and the effect sizes. The results of the WOMAC were consistent with the physical health scales of SF-36.ConclusionsThe sense of coherence was associated with psychosocial health dimensions but hardly with physical health. The higher the load of a scale on the psychosocial dimension the higher was its correlation to the sense of coherence. This is in contrast to the idea of Antonovsky who predicted high associations with both mental and physical health.

Objective: To determine and compare the sensitivity to change of the condition-specific cervical Northern American Spine Society (NASS) and the generic Short Form 36 (SF-36). Design: Prospective cohort study. Subjects: One hundred and seventy five patients after whiplash injury. Interventions: Four-week inpatient interdisciplinary pain management programme. Main measures, analysis: Responsiveness of the NASS and the SF-36 was quantified by effect size and standardized response mean and compared within the same construct by the modified Jacknife test. Ability to detect improvement was compared using sensitivities determined from receiver operating characteristics curves. Results: In pain, the NASS was comparable responsive to the SF-36 at the one-month follow-up (n = 175): effect sizes: 0.62 (NASS) versus 0.61 (SF-36), P = 0.914. The NASS was less responsive than the SF-36 in function: 0.23 versus 0.63, P < 0.001 and in pain+function: 0.35 versus 0.58 (P = 0.001). These relationships remained consistent using standardized response means, at the six-month follow-up (n = 103), and in the comparison of the sensitivities. Sensitivities at one month, pain: 70% (NASS) versus 62% (SF-36), P = 0.234; function: 65% versus 80%, P = 0.002; pain+function: 68% versus 78%, P = 0.035. The six-month data were similar. Conclusions: The generic SF-36 was more responsive in function and equally responsive in pain when compared to the condition-specific NASS. The SF-36 can be recommended as a responsive instrument for measurement of pain and function in chronic whiplash syndrome.

BackgroundThis cross validation study examined the reliability of the Multidimensional Pain Inventory (MPI) and the stability of the Multidimensional Pain Inventory Classification System of the empirically derived subgroup classification obtained by cluster analysis in chronic musculoskeletal pain. Reliability of the German Multidimensional Pain Inventory was only examined once in the past in a small sample. Previous international studies mainly involving fibromyalgia patients showed that retest resulted in 33–38% of patients being assigned to a different Multidimensional Pain Inventory subgroup classification.MethodsParticipants were 204 persons with chronic musculoskeletal pain (82% chronic non-specific back pain). Subgroup classification was conducted by cluster analysis at 4 weeks before entry (=test) and at entry into the pain management program (=retest) using Multidimensional Pain Inventory scale scores. No therapeutic interventions in this period were conducted. Reliability was quantified by intraclass correlation coefficients (ICC) and stability by kappa coefficients (κ).ResultsReliability of the Multidimensional Pain Inventory scales was least with ICC = 0.57 for the scale life control and further ranged from ICC = 0.72 (negative mood) to 0.87 (solicitous responses) in the other scales. At retest, 82% of the patients in the Multidimensional Pain Inventory cluster interpersonally distressed (κ = 0.69), 80% of the adaptive copers (κ = 0.58), and 75% of the dysfunctional patients (κ = 0.70) did not change classification. In total, 22% of the patients changed Multidimensional Pain Inventory cluster group, mainly into the adaptive copers subgroup.ConclusionTest-retest reliability of the German Multidimensional Pain Inventory was moderate to good and comparable to other language versions. Multidimensional Pain Inventory subgroup classification is substantially stable in chronic back pain patients when compared to other diagnostic groups and other examiner-based subgroup Classification Systems. The MPI Classification System can be recommended for reliable and stable specification of subgroups in observational and interventional studies in patients with chronic musculoskeletal pain.

BACKGROUND Little is known about comprehensively measured health and quality of life of lower limb lymphedema (LLL). The aim of this study was to determine health and quality of life of LLL patients stratified by primary and secondary lymphedema compared to a normative population-based data stratified by age, sex and comorbidity. PATIENTS AND METHODS A cross-sectional study of patients after treatment at the department of angiology of a rehabilitation clinic was conducted. Self-assessment was performed by the Short Form 36 (SF-36) and two condition-specific measures. RESULTS Primary LLL (n = 52) 75 % female, mean age 47.1 years) reported health comparable to normative values, e. g. SF-36 physical functioning 80.4 (norm 84.1, p = 0.512) and SF-36 vitality 62.7 (59.7, p = 0.117) (mean scores, 100 = best). Secondary LLL (n = 60, 68 % female, mean age 60.6 years) scored 68.1 (73.9, p = 0.049) and 55.2 (56.2, p = 0.800) on the corresponding scales. Mean symptoms and function scores on the specific measures ranged from 70.0 to 83.1 for primary LLL (100 = best) and from 63.3 to 80.6 for secondary LLL. Function, vitality and both SF-36 role dimensions were higher in primary LLL than in secondary LLL, (mean SF-36 vitality 62.7 versus 55.2, p = 0.035). CONCLUSIONS Overall health and quality of life was high and comparable to the general population norms in primary LLL. The same was true for most psycho-social scales in secondary LLL whereas functionally some deficits were recorded. Cancer as the most frequent cause for secondary LLL may affect health in these dimensions. Reported negative effects of LLL seem to be well compensated, especially in primary LLL and under optimal treatment.

Felix Angst; Martin Verra; Susanne Lehmann; Thomas Benz; André Aeschlimann

OBJECTIVES To quantify pain, function, and health-related quality of life in comparison with normative data, and to quantify intervention effects. DESIGN Naturalistic cohort study without a control group. Correction of the effects observed during the intervention by those observed during waiting time prior to the intervention. SETTING Inpatient rehabilitation clinic. PARTICIPANTS Patients with hip (n=88) and knee (n=164) osteoarthritis. INTERVENTION Comprehensive, multidisciplinary inpatient rehabilitation lasting 3 weeks. MAIN OUTCOME MEASURES Medical Outcomes Study 36-Item Short-Form Health Survey and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). RESULTS Four or more comorbid conditions had 45.3% of the hip and 51.8% of the knee patients on entry to and discharge from the clinic. On entry, physical health and some dimensions of psychosocial health were significantly diminished compared with population norms. At discharge, hip osteoarthritis had improved by a corrected effect size of .20 to .47 in pain, .04 to .39 in function, and -.04 to .32 in psychosocial health. Knee osteoarthritis showed a corrected effect size of .43 to .62 in pain, .19 to .51 in function, and .19 to .30 in psychosocial health. All but 1 effect in WOMAC pain and WOMAC function were higher than the minimal clinically important differences. CONCLUSIONS Hip and knee osteoarthritis patients admitted to the inpatient intervention were affected by a substantial burden of disease and comorbidities. Inpatient rehabilitation resulted in small to moderate, statistically significant, and clinically important improvements in pain, function, and psychosocial health.

Isabelle Fuss; Felix Angst; Susanne Lehmann; Beat A. Michel; André Aeschlimann

Objective:To determine the factors associated with pain relief and improved physical functioning in chronic pain patients during outpatient management in the first 5 months immediately after a standardized inpatient pain management program. Methods:Prospective cohort study using standardized questionnaires on sociodemographic data, disease outcome, psychosocial factors, change in behavior, and outpatient therapies on discharge from inpatient rehabilitation and during the 5-month follow-up at home (observation period). Stepwise forward multivariate linear regression analysis examined the correlation of these factors with change in pain severity and change in physical functioning. Results:The study included 80.1% female patients, 90.0% had at least 1 comorbidity and 62.9% had chronic pain for≥5 years. On average, pain intensity and depression worsened slightly during the observation period, but the other outcomes remained almost stable. Relief from anxiety (20.7% explained variance) and low baseline depression (5.5%) were the most important predictors for pain relief. Relief from anxiety (13.3%) and low baseline depression (7.1%) were most strongly associated with functional improvement. Conclusions:This study found a strong association of change in pain severity and physical functioning with change in baseline level of affective health and coping during the first outpatient management period after inpatient rehabilitation. As a consequence, it may be possible to improve the treatment of chronic pain by therapy of mood and coping.

Abstract Whiplash injury associated disorders (WAD) cause high costs for public health care. Neck pain is number 16 on the global prevalence lists for the 50 most common sequelae. It is of importance to obtain long-term data on disability and working capacity outcomes after rehabilitation. Long-term prospective data of the outcome course of whiplash are sparse. The aim of this study was to quantify improvements of pain, function/role performance, vitality, and working capacity 5 years after whiplash injury and to compare the state of health to normative values at 5 years after rehabilitation. In this naturalistic, observational, prospective cohort study, 115 patients were assessed 5 years (60 months) after a multidisciplinary rehabilitation program. The assessment set consisted of the Short Form 36 (SF-36), parts of the North American Spine Societys cervical spine assessment questionnaire (NASS) and the coping strategies questionnaire (CSQ). The effects were quantified by effect size (ES) and standardized response mean (SRM). Score differences over the course were tested by the Wilcoxon–Mann–Whitney U test for significance. Comparing data between entry and 60 months after rehabilitation 8 of 15 parameters improved with large ES/SRM. Outcome between 6 and 60 months showed small to moderate ES/SRM. Working capacity increased from 0 at entry to rehabilitation to 21 h/wk at 6 months and to 30 h/wk at 60 months follow-up. After large improvements in health and working capacity in the mid-term, further important improvements were observed in the long-term course. It can be hypothesized that part of those can be attributed to the interventions during inpatient rehabilitation, for example, due to better coping strategies.

Multidimensional minimal clinically important differences in knee osteoarthritis after comprehensive rehabilitation: a prospective evaluation from the Bad Zurzach Osteoarthritis Study

Felix Angst; Thomas Benz; Susanne Lehmann; André Aeschlimann; Jules Angst

Objective To determine minimal clinically important differences (MCIDs) for improvement and worsening in various health dimensions in knee osteoarthritis under conservative therapy. Methods Health, symptoms and function were assessed by the generic Short Form 36 and the condition-specific Western Ontario and McMaster Universities Osteoarthritis Index in n=190 patients with knee osteoarthritis before and after comprehensive rehabilitation intervention (3-month follow-up). By means of construct-specific transition questions, MCIDs were defined as the difference between the ‘slightly better/worse’ and the ‘almost equal’ transition response categories according to the ‘mean change method’. The bivariate MCIDs were adjusted for sex, age and baseline score to obtain adjusted MCIDs by multivariate linear regression. They were further standardised as (baseline) effect sizes (ESs), standardised response means (SRMs) and standardised mean differences (SMDs) and compared with the minimal detectable change with 95% confidence (MDC95). Results Multivariate, adjusted MCIDs for improvement ranged from 2.89 to 16.24 score points (scale 0–100), corresponding to ES=0.14 to 0.63, SRM=0.17 to 0.61 and SMD=0.18 to 0.72. The matching results for worsening were –5.80 to –12.68 score points, ES=–0.30 to –0.56, SRM=–0.35 to –0.52 and SMD=–0.35 to –0.58. Almost all MCIDs were larger than the corresponding MDC95s. Conclusions This study presents MCIDs quantified according to different methods over a comprehensive range of health dimensions. In most health dimensions, multivariate adjustment led to higher symmetry between the MCID levels of improvement and worsening. MCIDs expressed as standardised effect sizes (ES, SRM, SMD) and adjusted by potential confounders facilitate generalisation to the results of other studies.
