Pain Neuroscience Education Following Arthroscopic Rotator Cuff Repair for Patients With Rotator Cuff Tears: A Double-Blind Randomized Controlled Clinical Trial

OBJECTIVE

This trial examines the efficacy of the pain neuroscience education on clinical outcomes in patients with arthroscopic rotator cuff repair.

DESIGN

A total of 36 participants undergoing arthroscopic rotator cuff repair were assigned to either the experimental group ( n = 18) or control group ( n = 18) in this randomized study. A 6-wk-long conventional physiotherapy program was administered for both groups. In addition, a pain neuroscience education protocol was administered for the experimental group for a whole period of 6 wks (1 session/week, 15-60 mins per session). The primary outcomes were to compare pretreatment and posttreatment scores of the experimental versus control groups on the pain and disability. Our secondary outcomes included the comparisons of scores on the catastrophizing, anxiety, depression, kinesiophobia, and quality of life. The participants were assessed both at baseline and posttreatment.

RESULTS

The improvement in pain catastrophizing, anxiety, depression, and kinesiophobia was greater in the experimental group ( P < 0.05). The improvement was similar in both groups in terms of the rest of outcome measures.

CONCLUSIONS

This study showed that the pain neuroscience education improved only psychological aspects of the chronic pain in arthroscopic rotator cuff repair. Therefore, adding pain neuroscience education to the conventional program might be useful to improve pain catastrophizing, anxiety, depression, and kinesiophobia in patients with arthroscopic rotator cuff repair.

Are Improvements in Pain Neurophysiology Knowledge Following Pain Science Education Associated With Improved Outcomes in People With Chronic Pain?: A Systematic Review and Meta-analysis

OBJECTIVE

This systematic review and meta-analysis aimed to determine the association between changes in patients' pain knowledge after pain science education (PSE) with treatment outcomes in people with chronic pain.

METHODS

Six electronic databases and 2 clinical trial registries were searched from inception to September 15, 2021 for studies where participants received PSE and had their pain knowledge and clinical outcomes assessed before and after PSE. Meta-analyses were performed for pain intensity, kinesiophobia, and pain catastrophizing. Physical function and quality of life outcomes were synthesized narratively. Risk of bias was assessed using the Cochrane tool for nonrandomized studies and the quality of evidence was assessed using GRADE.

RESULTS

Fourteen studies (n=1500 participants) were included. Meta-analyses revealed no significant associations between short-term (<12 wk) changes in pain neurophysiology knowledge with changes in pain intensity (n=1075, r=-0.01, 95% CI =-0.14 to 0.13, very low certainty), kinesiophobia (n=152, r=0.02, 95% CI =-0.27 to 0.24, very low certainty) and pain catastrophizing (n=976, r=-0.03, 95% CI=-0.18 to 0.11, low certainty). No significant associations were found between short-term changes in pain neurophysiology knowledge and physical function or quality of life either.

DISCUSSION

These findings do not support a short-term association between improvements in pain neurophysiology knowledge and better treatment outcomes in people with chronic pain. Increased understanding of how PSE works, as well as better ways to measure it, may help clinicians deliver more targeted education to help patients reconceptualize pain and promote engagement in active treatment strategies (eg, exercise).

What do community-dwelling older adults with chronic pain value in a program of combined pain neuroscience education plus exercise?

OBJECTIVE

To explore the experience of older adults after a pain neuroscience education (PNE) and exercise intervention.

METHODS

Focus group interviews were conducted with 14 older adults after receiving 8-weekly sessions of PNE and exercise and encompassed older adults' perceptions of the intervention and its impact. Interviews were transcribed verbatim and analyzed by 3 researchers using thematic analysis in a five-step approach (compiling, disassembling, reassembling, interpreting, and concluding).

RESULTS

Three themes emerged: pain reconceptualization, motivational factors, and perceived improvements. Pain reconceptualization was illustrated by participants' ability to use language that related to PNE concepts (n = 12), increased self-efficacy (n = 5), and adjusted emotions (n = 2) and behaviors (n = 6). Motivational factors were the group-administered intervention (n = 6) and the physical therapists' communication skills (n = 10). The intervention was perceived as having a positive impact on sleep (n = 3), well-being (n = 6), and activity/ability to perform activities (n = 8).

CONCLUSION

Older adults understand PNE concepts and reconceptualize pain. PNE and exercise were perceived as having a positive impact on day-to-day life.

PRACTICE IMPLICATIONS

Mode of administration, communication skills, and rapport are aspects of the intervention that are valued by older adults. Also, PNE might be used as a strategy to increase older adults' adherence to physical activity.

Pain neuroscience education and physical exercise for patients with chronic spinal pain in primary healthcare: a randomised trial protocol

BACKGROUND

Chronic musculoskeletal pain affects more than 20% of the population, and the prevalence is increasing, causing suffering, loss of quality of life, disability, and an enormous expenditure on healthcare resources. The most common location for chronic pain is the spine. Many of the treatments used are mainly passive (pharmacological and invasive) and poor outcomes. The treatments currently applied in the public health system do not comply with the recommendations of the main clinical practice guidelines, which suggest the use of educational measures and physical exercise as the first-line treatment. A protocol based on active coping strategies is described, which will be evaluated through a clinical trial and which could facilitate the transfer of the recommendations of the clinical practice guidelines to a primary care setting.

METHODS

Randomised and multicentre clinical trials, which will be carried out in 10 Primary Care centres. The trial will compare the effect of a Pain Neuroscience Education program (six sessions, 10 h) and group physical exercise (18 sessions program carried out in six weeks, 18 h), with usual care physiotherapy treatment. Group physical exercise incorporates dual tasks, gaming, and reinforcement of contents of the educational program. The aim is to assess the effect of the intervention on quality of life, as well as on pain, disability, catastrophism, kinesiophobia, central sensitisation, and drug use. The outcome variables will be measured at the beginning of the intervention, after the intervention (week 11), at six months, and a year.

DISCUSSION

Therapeutic interventions based on active coping strategies are essential for the treatment of chronic pain and the sustainability of the Public Health System. Demonstrating whether group interventions have an effect size is essential for optimising resources in such a prevalent problem.
