Can physiotherapy in an interdisciplinary pain rehabilitation setting improve physical function? A long-term mixed methods follow-up study.

PURPOSE: The aim of this study was to describe chronic pain patients' perception of their physical function and treatment factors for improving or maintaining physical function long-term after the completion of an Interdisciplinary Pain Rehabilitation Program (IPRP) and to compare physical function before, directly after and at long-term follow-up (16-20 months after treatment). MATERIALS AND METHODS: Patients with severe nonmalignant chronic pain, participating in an IPRP at a specialist clinic, were eligible for inclusion in a convergent mixed methods study. Quantitative data included aerobic capacity, level of physical activity (PA) and self-efficacy for exercise. Qualitative data were collected through semi-structured interviews. RESULTS: The qualitative analysis resulted in one theme: Orientation change and two categories: Permission to feel self-worth and Reclaiming life, which illuminated factors that enabled a sustained increase in PA. The quantitative data (n = 11) showed a significantly increased maximal oxygen uptake (VO2max) from 2.46 l/min (SD = 0.9) at baseline to 2.63 l/min (SD = 0.9, p = .03) on completion of the program. VO2max was sustained at long-term follow-up (2.56 l/min (SD = 1.0, p = .24). CONCLUSION: This study indicates that an orientation change process through an IPRP can lead to increased physical function and a sustainable level of PA. Furthermore, it highlights the importance of a person-centered approach to enable sustainable change in patients with chronic pain.

Reliability and aspects of validity of the Swedish version of self-efficacy for exercise scale for patients with chronic pain.

BACKGROUND: Active, specific, and professionally led physical exercise is an effective treatment for chronic pain, and self-efficacy is correlated to positive treatment outcomes. At present, there is limited knowledge of self-efficacy for exercise in patients with chronic pain. PURPOSE: To evaluate the reliability and aspects of validity of the Swedish version of the Self-Efficacy for Exercise Scale (SEE-SV) in patients with chronic pain. METHODS: Patients with chronic pain were recruited from a specialist clinic. The Swedish version of the SEE was used. Reliability was evaluated through internal consistency, test-retest, and measurement error (standard error of measurement, SEM and smallest detectable change, SDC). Construct validity was calculated using the correlation between the SEE-SV and other well-established evaluation instruments. Content validity was evaluated both from a patient and a health-care professional perspective. RESULTS: In total, 44 patients, 31 women and 13 men (mean age 40 years), participated in the study. The SEE-SV had good test-retest reliability (intra-class correlation coefficient (ICC) = 0.95) and internal consistency (Cronbach's alpha = 0.97). Regarding measurement error, SEM was 4.9 and SDC 13.5. Moderate correlation was seen between SEE-SV and a pain-specific self-efficacy questionnaire (rs = 0.52). The majority of patients and health-care professionals considered the SEE-SV to be relevant and easy to understand. CONCLUSION: The SEE-SV showed a good internal consistency, item-to-total correlation, and test-retest reliability (ICC). A relatively high SDC indicates an individual variability of the test results. The content validity was satisfactory. Regarding the construct validity, further studies are needed.

Physical activity, self-efficacy and quality of life in patients with chronic pain, assessed during and 1 year after physiotherapy rehabilitation - a prospective follow-up study.

PURPOSE: The aim of this prospective cohort study was to evaluate the level of physical activity, self-efficacy and health-related quality of life in patients with chronic pain, at baseline and one year after physiotherapy rehabilitation at a specialist pain clinic. MATERIALS AND METHODS: All patients who underwent rehabilitation at the physiotherapy unit at the Pain Centre at Sahlgrenska University Hospital/Östra in Gothenburg during a nine-month period were asked to participate in the study. The participants were evaluated regarding self-efficacy, health-related quality of life (HRQoL) and physical activity during physiotherapy treatment and one year later. Physical activity was measured both subjectively (self-reported physical activity) and objectively (accelerometer). RESULTS: Out of 42 patients who participated in the baseline evaluation, 28 (19 women and nine men) were included in the one-year follow-up. The patients had increased levels of vigorous physical activity at one-year follow-up, without deterioration of pain. There were no significant changes regarding self-efficacy and HRQoL. Levels of physical activity and perceived physical function may be associated to levels of physical activity 1 year after rehabilitation. CONCLUSION: Patients with chronic pain can increase their level of vigorous physical activity after a period of rehabilitation without deterioration of pain.IMPLICATIONS FOR REHABILIATIONPhysical activity is an important part of rehabilitation for chronic pain patients, but many patients expect more pain after exercise, which they fear may affect performance and maintenance of physical activity.Patients with chronic pain at a specialist clinic increased their level of vigorous physical activity one year after physiotherapist led rehabilitation without deterioration of pain.Levels of physical activity and perceived physical function during rehabilitation may predict levels of physical activity 1 year after rehabilitation.Physiotherapist led rehabilitation seems to be beneficial for long-term improved physical activity in patients with chronic pain.
