Implementation of physiotherapy-led lung ultrasound in the intensive care unit.

The use of lung ultrasound (LUS) in clinical settings is emerging as an important tool in the assessment of lung pathology and/or function and has gained considerable acceptance. LUS is being integrated into clinical care by trained respiratory physiotherapists and has been shown to influence physiotherapists' clinical decision-making in the respiratory management of patients. Considering the use of LUS by physiotherapy is in its infancy and still evolving, there is likely variability in the ability and confidence of physiotherapists to use LUS in clinical practice, both in Australia and internationally. While the UK has had a rapid increase in the number of LUS-accredited physiotherapists (n = 111), the number of LUS-accredited physiotherapists in Australia remains very low (n = 4). There is a growing body of work in the UK on physiotherapy-led LUS in respiratory care, however, there is currently little work published on the practicalities of training and establishing physiotherapy-led LUS in Australia. This report describes the training and implementation of physiotherapy-led LUS in the intensive care unit from a regional hospital perspective.

Development of a physiotherapy-led bronchoscopy service: a regional hospital perspective.

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.

Diagnosis and management of chronic hip and knee pain in a Tasmanian orthopaedic clinic: a study assessing the diagnostic and treatment planning decisions of an advanced scope physiotherapist.

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.

Physiotherapy education and training prior to upper abdominal surgery is memorable and has high treatment fidelity: a nested mixed-methods randomised-controlled study.

OBJECTIVES: To (1) assess memorability and treatment fidelity of pre-operative physiotherapy education prior to elective upper abdominal surgery and, (2) to explore patient opinions on pre-operative education. DESIGN: Mixed-methods analysis of a convenience sample within a larger parallel-group, double-blinded, randomised controlled trial with concealed allocation and intention-to-treat analysis. SETTING: Tertiary Australian hospital. PARTICIPANTS: Twenty-nine patients having upper abdominal surgery attending pre-admission clinic within six-weeks of surgery. INTERVENTION: The control group received an information booklet about preventing pulmonary complications with early ambulation and breathing exercises. The experimental group received an additional face-to-face 30-minute physiotherapy education and training session on pulmonary complications, early ambulation, and breathing exercises. OUTCOME MEASURES: Primary outcome was proportion of participants who remembered the taught breathing exercises following surgery. Secondary outcomes were recall of information sub-items and attainment of early ambulation goals. These were measured using standardised scoring of a semi-scripted digitally-recorded interview on the 5th postoperative day, and the attainment of early ambulation goals over the first two postoperative days. RESULTS: Experimental group participants were six-times more likely to remember the breathing exercises (95%CI 1.7 to 22) and 11-times more likely (95%CI 1.6 to 70) to report physiotherapy as the most memorable part of pre-admission clinic. Participants reported physiotherapy education content to be detailed, interesting, and of high value. Some participants reported not reading the booklet and professed a preference for face-to-face information delivery. CONCLUSION: Face-to-face pre-operative physiotherapy education and training prior to upper abdominal surgery is memorable and has high treatment fidelity. TRIAL REGISTRATION: ACTRN-12613000664741.

Thinking about movement hurts: the effect of motor imagery on pain and swelling in people with chronic arm pain.

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.

Tactile discrimination, but not tactile stimulation alone, reduces chronic limb pain.

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.

Faulty proprioceptive information disrupts motor imagery: an experimental study.

QUESTION: Does faulty proprioceptive input disrupt the internal model of the body that the brain uses to control movement? DESIGN: Randomised, within-participant experimental study. PARTICIPANTS: Twenty-two (13 F) healthy adults. INTERVENTION: Participants performed a motor imagery task that involved making left/right judgements of pictured right and left hands in 16 different postures under five conditions involving stimuli being applied to the experimental (L) hand. The five conditions were: vibration (of the wrist extensor tendons to elicit the illusion of wrist flexion), sham (vibration of the ulna styloid), active flexion, passive flexion, and control (no stimulus). OUTCOME MEASURES: Accuracy and response time of the control (R) hand in making left/right judgements of the pictures. RESULTS: Response time during vibration was longer for those who reported the illusion of wrist flexion (n = 18) than for those who did not (p < 0.01) whereas accuracy was unaffected (p = 0.71). In those who reported the illusion, accuracy was unaffected by condition, hand or picture (p > 0.21). Response time during vibration was 910 ms longer (95% CI 730 to 1090) for pictures of the experimental (L) hand (mean 2731 ms, 95% CI 2543 to 2918) than it was for pictures of the control (R) hand (mean 1822 ms, 95% CI 1634 to 2009), and approximately 580 ms longer (95% CI 380 to 785) for pictures of either hand during any other condition (p < 0.025). CONCLUSION: Faulty proprioceptive input disrupted this motor imagery task, which suggests it can disrupt the model of the limb that the brain uses for movement.

Expectation of pain replicates the effect of pain in a hand laterality recognition task: bias in information processing toward the painful side?

BACKGROUND: People in pain, or expecting pain, sometimes bias their attention towards pain-relevant cues. Perhaps they also bias their attention towards the body part in question. AIM: To determine if experimentally induced pain, and the expectation of pain, involve an information processing bias towards the hand in question. METHODS: Seventeen asymptomatic subjects performed a hand laterality recognition task during three conditions: control, during hand pain induced by intramuscular injection of hypertonic saline (pain), and during expectation of hand pain, induced by isotonic saline injection (expectation). Mean response time (RT) was determined for three 45 s epochs within each condition and RT was compared between hands, conditions and epochs using a 2 x 3 x 3 repeated measures multivariate analysis of variance. RESULTS: There was a hand x condition interaction and a hand x condition x epoch interaction (p<0.05 for both). RT to recognise the opposite hand was approximately 600 ms longer during epochs when subjects were in pain or expected pain than during control trials. During those epochs, RT to recognise the opposite hand was approximately 600 ms longer than RT to recognise the injected hand, which was consistent across conditions and across epochs. CONCLUSIONS: 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.
