Chronic pain is often associated with reduced tactile acuity. A relationship exists between pain intensity, tactile acuity and cortical reorganisation. When pain resolves, tactile function improves and cortical organisation normalises. Tactile acuity can be improved in healthy controls when tactile stimulation is associated with a behavioural objective. We hypothesised that, in patients with chronic limb pain and decreased tactile acuity, discriminating between tactile stimuli would decrease pain and increase tactile acuity, but tactile stimulation alone would not. Thirteen patients with complex regional pain syndrome (CRPS) of one limb underwent a waiting period and then approximately 2 weeks of tactile stimulation under two conditions: stimulation alone or discrimination between stimuli according to their diameter and location. There was no change in pain (100 mm VAS) or two-point discrimination (TPD) during a no-treatment waiting period, nor during the stimulation phase (p > 0.32 for both). Pain and TPD were lower after the discrimination phase [mean (95% CI) effect size for pain VAS = 27 mm (14-40 mm) and for TPD = 5.7 mm (2.9-8. ), p < 0.015 for both]. These gains were maintained at three-month follow-up. We conclude that tactile stimulation can decrease pain and increase tactile acuity when patients are required to discriminate between the type and location of tactile stimuli.

Objective. Chronic painful disease is associated with pain on movement, which is presumed to be caused by noxious stimulation. We investigated whether motor imagery, in the absence of movement, increases symptoms in patients with chronic arm pain. Methods. Thirty-seven subjects performed a motor imagery task. Pain and swelling were measured before, after, and 60 minutes after the task. Electromyography findings verified no muscle activity. Patients with complex regional pain syndrome (CRPS) were compared with those with non-CRPS pain. Secondary variables from clinical, psychophysical, and cognitive domains were related to change in symptoms using linear regression. Results. Motor imagery increased pain and swelling. For CRPS patients, pain (measured on a 100-mm visual analog scale) increased by a mean ؎ SD of 5.3 ؎ 3.9 mm and swelling by 8% ؎ 5%. For non-CRPS patients, pain increased by 1.4 ؎ 4.1 mm and swelling by 3% ؎ 4%. There were no differences between groups (P > 0.19 for both). Increased pain and swelling related positively to duration of symptoms and performance on a left/right judgment task that interrogated the body schema, autonomic response, catastrophic thoughts about pain, and fear of movement (r > 0.42, P < 0.03 for all). Conclusion. Motor imagery increased pain and swelling in patients with chronic painful disease of the arm. The effect increased in line with the duration of symptoms and seems to be modulated by autonomic arousal and beliefs about pain and movement. The results highlight the contribution of cortical mechanisms to pain on movement, which has implications for treatment.

Both pain and the expectation of pain increased RT to recognise the opposite hand. The findings are consistent with a bias in information processing toward the painful or impending painful hand.

In healthy volunteers, incongruent proprioceptive input does not cause discomfort or pain but does evoke feelings of peculiarity, swelling and foreignness in the limb.

Faulty proprioceptive input disrupted this motor imagery task, which suggests it can disrupt the model of the limb that the brain uses for movement.

The aim of this study is to investigate the clinical effectiveness of an advanced practice physiotherapist triaging patients referred from primary care to the orthopaedic clinic with chronic hip and knee pain. An exploratory study design was used to assess 87 consecutive patients referred from general practice in Northern Tasmania. Patients were assessed by both an advanced practice physiotherapist and a consultant orthopaedic surgeon. Diagnostic and treatment decisions were compared, with the orthopaedic consultant decision defined as the gold standard. By using these decisions, over and under referral rates to orthopaedics could be calculated, as well as the surgical conversion rate. Conservative care of patients referred to the orthopaedic clinic with hip and knee pain was limited. The diagnostic agreement between the advanced scope physiotherapist and the orthopaedic surgeon was almost perfect (weighted kappa 0.93 (95% CI 0.87–1.00)), with treatment agreement substantial (weighted kappa 0.75 (95% CI 0.62–0.89)). Under a physiotherapist-led triage service, the surgical conversion rate doubled from 38% to 78%. An advanced physiotherapist assessing and treating patients with chronic hip and knee pain made decisions that match substantially with decisions made by an orthopaedic consultant. A model of care utilising an advanced physiotherapist in this way has the potential to support high-quality orthopaedic care in regional centres.

Extended scope of practice (ESoP) and advanced scope of practice (ASoP) physiotherapy roles have been in place in the UK for over 20 years. However, interest in these types of services appears to be only just evolving within Australia. Although ESoP and/or ASoP cardiorespiratory roles in intensive care units (ICU) may be perceived to be more achievable in large metropolitan teaching hospitals, at least 67% of Australian ICUs provide physiotherapy services. Very little has been published on the practicalities (e.g. training pathways, evidence for use and guidelines) of developing advanced or extended scope cardiorespiratory physiotherapy services within Australian ICUs. This report describes the development and implementation of a physiotherapy-led bronchoscopy service from a regional hospital perspective. What is known about the topic? Although ESoP and ASoP physiotherapy roles are well established in the UK, such services appear to be only just evolving in Australia. Clarity on the definitions of extended and advanced physiotherapy roles have been articulated by the Australian Physiotherapy Association. However, there is a paucity of evidence published on the practicalities of establishing advanced or extended scope cardiorespiratory physiotherapy services within Australian ICUs. What does this paper add? One of the main emerging areas of ESoP and/or ASoP in the cardiorespiratory field is the use of bronchoscopy by physiotherapists. This paper describes the framework, implementation, limitations and barriers of developing a physiotherapy-led bronchoscopy service from a regional hospital perspective. What are the implications for practitioners? This paper allows the potential for our credentialing and practice framework model to be transferred in other public hospitals commencing or considering implementing physiotherapy-led bronchoscopy services within their ICU.
