Introduction
My interests are the management of chronic pain. This includes best practice in synthesizing the available evidence of the effectiveness of interventions and the mechanisms of chronic back pain.
I have interests in the development of clinical practice guidelines and was on the guideline development group of the NICE guidelines for the management of low back pain and sciatica (NG59).
I am joint Co-ordinating editor of the Cochrane Pain, Palliative and Supportive Care review group (PaPaS).

The personal, social and economic burden of chronic pain is enormous. Yet patients with chronic pain, clinicians and the public are often poorly served by an evidence architecture that contains multiple structural weaknesses which reduce confidence in treatment practice. Weaknesses include incomplete research governance, a lack of diversity and inc...
Background
Randomised controlled trials (RCTs) inform healthcare decisions. Unfortunately, some published RCTs contain false data, and some appear to have been entirely fabricated. Systematic reviews are performed to identify and synthesise all RCTs which have been conducted on a given topic. This means that any of these 'problematic studies' are l...

To evaluate the effectiveness of physical activity, education abou...
We previously conducted an exploration of the trustworthiness of a group of clinical trials of cognitive behavioural therapy (CBT) and exercise in spinal pain. We identified multiple concerns in eight trials, judging them untrustworthy. In this study, we systematically explored the impact of these trials ("index trials") on results, conclusions and...
Background:
Complex regional pain syndrome (CRPS) is a chronic pain condition that usually occurs in a limb following trauma or surgery. It is characterised by persisting pain that is disproportionate in magnitude or duration to the typical course of pain after similar injury. There is currently no consensus regarding the optimal management of CRP...
Retraction is a mechanism for correcting the scientific record and alerts readers when a study contains unreliable or flawed data. Such data may arise from error or research misconduct. Studies examining the landscape of retracted publications provide insight into the extent of unreliable data and its effect on a medical discipline. We aimed to exp...
Background:
Pharmacological interventions are the most used treatment for low back pain (LBP). Use of evidence from systematic reviews of the effects of pharmacological interventions for LBP published in the Cochrane Library, is limited by lack of a comprehensive overview.

Background:
Complex regional pain syndrome (CRPS) is a painful and disabling condition that usually manifests in response to trauma or surgery and is associated with significant pain and disability. CRPS can be classified into two types: type I (CRPS I) in which a specific nerve lesion has not been identified and type II (CRPS II) where there is a...
Evidence-based medicine is replete with studies assessing quality and bias, but few evaluating research integrity or trustworthiness. A recent Cochrane review of psychological interventions for chronic pain identified trials with a shared lead author with highly divergent results. We sought to systematically identify all similar trials from this au...
Background:
Implanted spinal neuromodulation (SNMD) techniques are used in the treatment of refractory chronic pain. They involve the implantation of electrodes around the spinal cord (spinal cord stimulation (SCS)) or dorsal root ganglion (dorsal root ganglion stimulation (DRGS)), and a pulse generator unit under the skin. Electrical stimulation...
We aimed to evaluate the evidence reported to underpin exercise dose in randomised controlled trials (RCTs) using strengthening exercise in RA. We searched six different databases between 1 January 2000 and 3 April 2019. We included RCTs, where a main component of the intervention and/or control used strengthening exercise. Evidence sources cited t...

The burden that low back pain (LBP) presents to sufferers and society is well established. This ubiquitous condition is served by a complex global clinical marketplace offering a wide range of assessment alternatives and accompanying interventions. Yet, while the costs of care are rising, the global burden does not appear to be diminishing. Conside...
As a potential high-yield tool for disseminating information that can reach many people, social media is transforming how clinicians, the public, and policy makers are educated and find new knowledge associated with research-related information. Social media is available to all who access the internet, reducing selected barriers to acquiring origin...
Introduction: International clinical guidelines for Complex Regional Pain Syndrome recommend a wide range and variation of rehabilitation therapies as the core treatment. It is likely that most therapists employ a range of approaches when managing people with Complex Regional Pain Syndrome but a recent Cochrane review identified little evidence rel...
Chronic pain can be associated with movement abnormalities. The primary motor cortex (M1) has an essential role in the formulation and execution of movement. A number of changes in M1 function have been reported in studies of people with chronic pain. This review systematically evaluated the evidence for altered M1 structure, organization, and func...

Background:
Neuropathic pain, which is due to nerve disease or damage, represents a significant burden on people and society. It can be particularly unpleasant and achieving adequate symptom control can be difficult. Non-pharmacological methods of treatment are often employed by people with neuropathic pain and may include transcutaneous electrica...
The presence of bimodal outcome distributions has been used as a justification for conducting responder analyses, in addition to, or in place of analyses of the mean between-group difference, in clinical trials and systematic reviews of interventions for pain. The aim of this study was to investigate the distribution of participants' pain outcomes...
Background:
Cerebral palsy (CP) is a neurodevelopmental disorder resulting from an injury to the developing brain. It is the most common form of childhood disability with prevalence rates of between 1.5 and 3.8 per 1000 births reported worldwide. The primary impairments associated with CP include reduced muscle strength and reduced cardiorespirato...
Given the scale and cost of the low back pain problem, it is imperative that healthcare professionals involved in the care of people with low back pain have access to up-to-date, evidence-based information to assist them in treatment decision-making. Clinical guidelines exist to promote the consistent best practice, to reduce unwarranted variation...
Navigating the maze of evidence relating to clinical effectiveness in chronic pain is a challenge. In order to do it successfully we need an understanding of the various sources of bias and error that can occur in clinical trials, the broader biases and imperfect practices in the clinical research ecosystem, and all the ways in which we personally...

The presence of bimodal outcome distributions has been used as a justification for conducting responder analyses, in addition to, or in place of analyses of mean difference, in clinical trials and systematic reviews of interventions for pain. The aim of this study was to investigate the distribution of participants' pain outcomes for ev...
Upregulation of defensive reflexes such as the nociceptive flexion reflex (NFR) has been attributed to sensitisation of peripheral and spinal nociceptors and is often considered biomarkers of pain. Experimental modulation of defensive reflexes raises the possibility that they might be better conceptualised as markers of descending cognitive control...
Introduction:
Low back pain is the leading worldwide cause of disability, and results in significant personal hardship. Most available treatments, when tested in high-quality randomised, controlled trials, achieve only modest improvements in pain, at best. Recently, treatments that target central nervous system function have been developed and tes...
Background:
This review is an update of a previously published review in the Cochrane Database of Systematic Reviews, 2005, Issue 4 (and last updated in the Cochrane Database of Systematic Reviews, 2013 issue 8), on local anaesthetic blockade (LASB) of the sympathetic chain to treat people with complex regional pain syndrome (CRPS).
Objectives:...
Perspective:
Several lines of evidence suggest that body perception might be disturbed in people with chronic low back pain, possibly contributing to the condition and offering a potential target for treatment. The Fremantle Back Awareness Questionnaire was developed as a quick and simple way of measuring back specific body-perception in people wi...
Background:
Complex regional pain syndrome (CRPS) is a painful and disabling condition that usually manifests in response to trauma or surgery. When it occurs, it is associated with significant pain and disability. It is thought to arise and persist as a consequence of a maladaptive pro-inflammatory response and disturbances in sympathetically-med...
