A proposed clinical conceptual model for the physiotherapy management of Complex Regional Pain Syndrome (CRPS).

There are no validated clinical models to show a reliable pathway of guaranteeing an effective recovery for Complex Regional Pain Syndrome (CRPS) with physiotherapy management. An array of medical, psychological and physiotherapy intervention methods show weak benefit. Spearman correlations, with significance p < 0.05, from an observational, prospective, longitudinal, multi-centre study of regional standard physiotherapy CRPS management showed complete recovery to be potentially associated with baseline factors of: better mental health; better functional ability and quality of life; higher scores of extraversion personality trait; lower scores of intraversion personality trait; and interventions such as concurrent prescription of the anticonvulsant secondary analgesia group and a higher intensity of physiotherapy education intervention. These correlations were integrated with the literature evidence and the crux of previously suggested models to conceptualise a clinical model that can contribute to the broader knowledge of physiotherapy management in CRPS that should be tested with future research.

Potential risk factors for the onset of complex regional pain syndrome type 1: a systematic literature review.

Anaesthetists in the acute and chronic pain teams are often involved in treating Complex Regional Pain Syndromes. Current literature about the risk factors for the onset of Complex Regional Pain Syndrome Type 1 (CRPS 1) remains sparse. This syndrome has a low prevalence, a highly variable presentation, and no gold standard for diagnosis. In the research setting, the pathogenesis of the syndrome continues to be elusive. There is a growing body of literature that addresses efficacy of a wide range of interventions as well as the likely mechanisms that contribute to the onset of CRPS 1. The objective for this systematic search of the literature focuses on determining the potential risk factors for the onset of CRPS 1. Eligible articles were analysed, dated 1996 to April 2014, and potential risk factors for the onset of CRPS 1 were identified from 10 prospective and 6 retrospective studies. Potential risk factors for the onset of CRPS 1 were found to include being female, particularly postmenopausal female, ankle dislocation or intra-articular fracture, immobilisation, and a report of higher than usual levels of pain in the early phases of trauma. It is not possible to draw definite conclusions as this evidence is heterogeneous and of mixed quality, relevance, and weighting strength against bias and has not been confirmed across multiple trials or in homogenous studies.

The Relationship between Beliefs about Pain and Functioning with Rheumatologic Conditions.

Pain beliefs influence understanding of pain mechanisms and outcomes. This study in rheumatologic conditions sought to determine a relationship between beliefs about pain and functioning. Participants in Arthritis New Zealand's (ANZ) exercise and education programmes were used. Demographic data and validated instruments used included the Arthritis Impact Measurement Scale 2nd version-Short Form (AIMS2-SF) to measure functioning, and two scales of organic and psychological beliefs in Pain Beliefs Questionnaires (PBQ) to measure pain beliefs. 236 Members of ANZ were surveyed anonymously with AIMS2-SF and PBQ, with a 61% response rate; 144 responses were entered into the database. This study used α of 0.05 and a 1-ß of 0.8 to detect for significant effect size estimated to be r = 0.25. Analysis revealed a significant relationship between organic beliefs scale of PBQ and functioning of AIMS2-SF, with an r value of 0.32 and P value of 0.00008. No relationship was found between psychological beliefs scale of PBQ and AIMS2-SF. Organic pain beliefs are associated with poorer functioning. Psychological pain beliefs are not. Beliefs might have been modified by ANZ programmes. Clinicians should address organic pain beliefs early in consultation. Causal links between organic pain beliefs and functioning should be clarified.

Multilevel lumbar fusion and postoperative physiotherapy rehabilitation in a patient with persistent pain.

There are no comparative randomised controlled trials of physiotherapy modalities for chronic low back and radicular pain associated with multilevel fusion. Physiotherapy-based rehabilitation to control pain and improve activation levels for persistent pain following multilevel fusion can be challenging. This is a case report of a 68-year-old man who was referred for physiotherapy intervention 10 months after a multilevel spinal fusion for spinal stenosis. He reported high levels of persistent postoperative pain with minimal activity as a consequence of his pain following the surgery. The physiotherapy interventions consisted of three phases of rehabilitation starting with pool exercise that progressed to land-based walking. These were all combined with transcutaneous electrical nerve stimulation (TENS) that was used consistently for up to 8 hours per day. As outcome measures, daily pain levels and walking distances were charted once the pool programme was completed (in the third phase). Phase progression was determined by shuttle test results. The pain level was correlated with the distance walked using linear regression over a 5-day average. Over a 5-day moving average, the pain level reduced and walking distance increased. The chart of recorded pain level and walking distance showed a trend toward decreased pain with the increased distance walked. In a patient undergoing multilevel lumbar fusion, the combined use of TENS and a progressive walking programme (from pool to land) reduced pain and increased walking distance. This improvement was despite poor medication compliance and a reported high level of postsurgical pain.
