The Effect of Neuroscience Education on Pain, Disability, Anxiety, and Stress in Chronic Musculoskeletal Pain

OBJECTIVE To evaluate the evidence for the effectiveness of neuroscience education (NE) for pain, disability, anxiety, and stress in chronic musculoskeletal (MSK) pain. DATA SOURCES Systematic searches were conducted on Biomed Central, BMJ.com, CINAHL, the Cochrane Library, NLM Central Gateway, OVID, ProQuest (Digital Dissertations), PsycInfo, PubMed/Medline, ScienceDirect, and Web of Science. Secondary searching (PEARLing) was undertaken, whereby reference lists of the selected articles were reviewed for additional references not identified in the primary search. STUDY SELECTION All experimental studies including randomized controlled trials (RCTs), nonrandomized clinical trials, and case series evaluating the effect of NE on pain, disability, anxiety, and stress for chronic MSK pain were considered for inclusion. Additional limitations: studies published in English, published within the last 10 years, and patients older than 18 years. No limitations were set on specific outcome measures of pain, disability, anxiety, and stress. DATA EXTRACTION Data were extracted using the participants, interventions, comparison, and outcomes (PICO) approach. DATA SYNTHESIS Methodological quality was assessed by 2 reviewers using the Critical Review Form-Quantitative Studies. This review includes 8 studies comprising 6 high-quality RCTs, 1 pseudo-RCT, and 1 comparative study involving 401 subjects. Most articles were of good quality, with no studies rated as poor or fair. Heterogeneity across the studies with respect to participants, interventions evaluated, and outcome measures used prevented meta-analyses. Narrative synthesis of results, based on effect size, established compelling evidence that NE may be effective in reducing pain ratings, increasing function, addressing catastrophization, and improving movement in chronic MSK pain. CONCLUSIONS For chronic MSK pain disorders, there is compelling evidence that an educational strategy addressing neurophysiology and neurobiology of pain can have a positive effect on pain, disability, catastrophization, and physical performance.

Thoracic Spine Thrust Manipulation Versus Cervical Spine Thrust Manipulation in Patients With Acute Neck Pain : A Randomized Clinical Trial

STUDY DESIGN Randomized clinical trial. OBJECTIVE To determine if patients who met the clinical prediction rule (CPR) criteria for the success of thoracic spine thrust joint manipulation (TJM) for the treatment of neck pain would have a different outcome if they were treated with a cervical spine TJM. BACKGROUND A CPR had been proposed to identify patients with neck pain who would likely respond favorably to thoracic spine TJM. Research on validation of that CPR had not been completed when this trial was initiated. In our clinical experience, though many patients with neck pain responded favorably to thoracic spine TJM, they often reported that their symptomatic cervical spine area had not been adequately addressed. METHODS Twenty-four consecutive patients, who presented to physical therapy with a primary complaint of neck pain and met 4 out of 6 of the CPR criteria for thoracic TJM, were randomly assigned to 1 of 2 treatment groups. The thoracic group received thoracic TJM and a cervical range-of-motion (ROM) exercise for the first 2 sessions, followed by a standardized exercise program for an additional 3 sessions. The cervical group received cervical TJM and the same cervical ROM exercise for the first 2 sessions, and the same exercise program given to the thoracic group for the next 3 sessions. Outcome measures collected at 1 week, 4 weeks, and 6 months from start of treatment included the Neck Disability Index, numeric pain rating scale, and Fear-Avoidance Beliefs Questionnaire. RESULTS Patients who received cervical TJM demonstrated greater improvements in Neck Disability Index (P ≤.001) and numeric pain rating scale (P ≤.003) scores at all follow-up times. There was also a statistically significant improvement in the Fear-Avoidance Beliefs Questionnaire physical activity subscale score at all follow-up times for the cervical group (P ≤.004). The number needed to treat to avoid an unsuccessful overall outcome was 1.8 at 1 week, 1.6 at 4 weeks, and 1.6 at 6 months. CONCLUSION Patients with neck pain who met 4 of 6 of the CPR criteria for successful treatment of neck pain with a thoracic spine TJM demonstrated a more favorable response when the TJM was directed to the cervical spine rather than the thoracic spine. Patients receiving cervical TJM also demonstrated fewer transient side-effects. LEVEL OF EVIDENCE Therapy, level 1b.

Preoperative Pain Neuroscience Education for Lumbar Radiculopathy A Multicenter Randomized Controlled Trial With 1-Year Follow-up

Study Design. Multicenter, randomized, controlled trial on preoperative pain neuroscience education (NE) for lumbar radiculopathy. Objective. To determine if the addition of NE to usual preoperative education would result in superior outcomes with regard to pain, function, surgical experience, and health care utilization postsurgery. Summary of Background Data. One in 4 patients after lumbar surgery (LS) for radiculopathy experience persistent pain and disability, which is nonresponsive to perioperative treatments. NE focusing on the neurophysiology of pain has been shown to decrease pain and disability in populations with chronic low back pain. Methods. Eligible patients scheduled for LS for radiculopathy were randomized to receive either preoperative usual care (UC) or a combination of UC plus 1 session of NE delivered by a physical therapist (verbal one-on-one format) and a NE booklet. Sixty-seven patients completed the following outcomes prior to LS (baseline), and 1, 3, 6, and 12 months after LS: low back pain (numeric rating scale), leg pain (numeric rating scale), function (Oswestry Disability Index), various beliefs and experiences related to LS (10-item survey with Likert scale responses), and postoperative utilization of health care (utilization of health care questionnaire). Results. At 1-year follow-up, there were no statistical differences between the experimental and control groups with regard to primary outcome measure of low back pain (P = 0.183), leg pain (P = 0.075), and function (P = 0.365). In a majority of the categories regarding surgical experience, the NE group scored significantly better: better prepared for LS (P = 0.001); preoperative session preparing them for LS (P < 0.001) and LS meeting their expectations (P = 0.021). Health care utilization post-LS also favored the NE group (P = 0.007) resulting in 45% less health care expenditure compared with the control group in the 1-year follow-up period. Conclusion. NE resulted in significant behavior change. Despite a similar pain and functional trajectory during the 1-year trial, patients with LS who received NE viewed their surgical experience more favorably and used less health care facility in the form of medical tests and treatments.

Preoperative education addressing postoperative pain in total joint arthroplasty: Review of content and educational delivery methods.

Objective: Evaluate content and educational delivery methods of preoperative education in total joint arthroplasties of the hip and knee (THA and TKA) addressing postoperative pain. Data sources: Systematic searches conducted on Biomed Central, BMJ.com, CINAHL, the Cochrane Library, NLM Central Gateway, OVID, ProQuest (Digital Dissertations), PsycInfo, PubMed/Medline, ScienceDirect, and Web of Science. Secondary searching (pearling) was undertaken. Data extraction: Data were extracted utilizing the participants, interventions, comparisons, and outcomes approach. Study selection: All randomized controlled trials (RCTs) evaluating the effect of preoperative education on postoperative pain in THA and TKA surgery were considered for inclusion. Limitations: Studies published in English; published within the last 20 years and patients over the age of 18. No limitations were set on specific outcome measures of pain. Data synthesis: This review included 13 RCTs involving a total of 1,017 subjects who underwent THA or TKA. Educational delivery methods comprised verbal one-on-one or group education sessions, delivered within 4 weeks of surgery lasting an average of 30 minutes, and accompanied by other written materials. The educational content centered on descriptions of preoperative preparation, hospital stay, surgical procedure, immediate/intermediate experiences, expectations following surgery, rehabilitation, encouragement/reassurance, and answering common question associated with the surgical experience. Conclusions: Preoperative education centered on a biomedical model of anatomy and pathoanatomy as well as procedural information has limited effect in reducing postoperative pain after THA and TKA surgeries. Preoperative educational sessions that aim to increase patient knowledge of pain science may be more effective in managing postoperative pain.

Conclusions: Current evidence supports the use of PNE for chronic MSK disorders in reducing pain and improving patient knowledge of pain, improving function and lowering disability, reducing psychosocial factors, enhancing movement, and minimizing healthcare utilization.

Safety of cervical spine manipulation: are adverse events preventable and are manipulations being performed appropriately? A review of 134 case reports

Abstract Background Cervical spine manipulation (CSM) is a commonly utilized intervention, but its use remains controversial. Purpose To retrospectively analyze all available documented case reports in the literature describing patients who had experienced severe adverse events (AEs) after receiving CSM to determine if the CSM was used appropriately, and if these types of AEs could have been prevented using sound clinical reasoning on the part of the clinician. Data sources PubMed and the Cumulative Index to Nursing and Allied Health were systematically searched for case reports between 1950 and 2010 of AEs following CSM. Study selection Case reports were included if they were peer-reviewed; published between 1950 and 2010; case reports or case series; and had CSM as an intervention. Articles were excluded if the AE occurred without CSM (e.g. spontaneous); they were systematic or literature reviews. Data extracted from each case report included: gender; age; who performed the CSM and why; presence of contraindications; the number of manipulation interventions performed; initial symptoms experienced after the CSM; and type of resultant AE. Data synthesis Based on the information gathered, CSMs were categorized as appropriate or inappropriate, and AEs were categorized as preventable, unpreventable, or unknown. Chi-square analysis with an alpha level of 0·05 was used to determine if there was a difference in proportion between six categories: appropriate/preventable, appropriate/unpreventable, appropriate/unknown, inappropriate/preventable, inappropriate/unpreventable, and inappropriate/unknown. Results One hundred thirty four cases, reported in 93 case reports, were reviewed. There was no significant difference in proportions between appropriateness and preventability, P = .46. Of the 134 cases, 60 (44·8%) were categorized as preventable, 14 (10·4%) were unpreventable and 60 (44·8%) were categorized as ‘unknown’. CSM was performed appropriately in 80·6% of cases. Death resulted in 5·2% (n = 7) of the cases, mostly caused by arterial dissection. Limitations There may have been discrepancies between what was reported in the cases and what actually occurred, since physicians dealing with the effects of the AE, rather than the clinician performing the CSM, published many of the cases. Conclusions This review showed that, if all contraindications and red flags were ruled out, there was potential for a clinician to prevent 44·8% of AEs associated with CSM. Additionally, 10·4% of the events were unpreventable, suggesting some inherent risk associated with CSM even after a thorough exam and proper clinical reasoning.

A neuroscience approach to managing athletes with low back pain

Low back pain (LBP) is a common complaint within the athletic population and is commonly managed through a biomedical approach. The injured or damaged structure causing the LBP is identified and treated, and complete recovery from the episode is expected. Clinical experience shows us that often, athletes with LBP will not recover from their episode and may continue their sports participation despite persistent pain, or they may limit participation. Recent neuroscience research into the biology of pain suggests that clinicians involved in the management of athletes with LBP should embrace a biopsychosocial approach by engaging the brain and nervous system. This manuscript provides an overview of such a biopsychosocial approach, and presents information on the neurobiology of the athletes pain experience.

Response of Pain Intensity to Soft Tissue Mobilization and Neurodynamic Technique: A Series of 18 Patients With Chronic Carpal Tunnel Syndrome

OBJECTIVE The purpose of this prospective case series was to examine the combined effects of soft tissue mobilization and nerve slider neurodynamic technique on pain and pressure sensitivity in women with chronic carpal tunnel syndrome (CTS). METHODS Eighteen women with a clinical and electromyographic diagnosis of CTS participated. Patients completed the numerical pain rating scale (NPRS) for current, worst, and lowest pain intensity and underwent pain pressure threshold (PPT) testing over the median, radial, and ulnar nerves; the C5-C6 zygapophyseal joint; the carpal tunnel; and the tibialis anterior muscle. Pain was assessed at baseline and 1-week follow-up, whereas PPT were assessed at baseline and immediately after and 1-week after intervention. Each received soft tissue mobilization and nerve slider neurodynamic technique directed at different anatomical sites of potential entrapment of the median nerve. RESULTS A decrease in the mean current intensity and worst level of hand pain (P<.01) was found 1 week after the treatment session (mean changes, 2.2±1.1 points). A treatment effect for PPT levels over the C5-C6 zygapophyseal joint (P<.001) was found: PPT increased bilaterally 1 week after the intervention. No other significant changes in PPT levels were found (P>.195). CONCLUSIONS The application of soft tissue mobilization and neurodynamic technique decreased the intensity of pain but did not change pressure pain sensitivity in this group of women with chronic CTS.

Use of Therapeutic Neuroscience Education to address psychosocial factors associated with acute low back pain: a case report

Abstract Acute low back pain (LBP) from injuries is prevalent in the work place. It has been shown that patients with psychosocial factors often progress with persistent pain and lead to significant workers compensation costs. Therapeutic Neuroscience Education (TNE) has been shown to be beneficial in changing a patient’s cognition regarding their pain state, which may result in decrease fear, anxiety and catastrophization. A 19-year-old female who developed LBP from a work injury was the patient for this case report. A physical examination, Numeric Pain Rating Scale (NRPS), Oswestry Disability Index (ODI), Fear-Avoidance Beliefs Questionnaire (FABQ), Keele STarT Back Screening Tool (Keele SBST) and Acute Low Back Pain Screening (ALBPS) Questionnaires were assessed during initial physical therapy visit and discharge. Treatment consisted of use of TNE, manual therapy and exercises. She attended five total visits over a 2-week period prior to full discharge. During the initial visit the patient reported NRPS = 3/10, ODI = 36%, FABQ-PA = 23, FABQ-W = 30, Keele SBST = 4/9, ALBPS = 101. At discharge the patient reported a 0 on all outcome questionnaires with ability to return to full work and no pain complaints.

Short-term effects of spinal thrust joint manipulation in patients with chronic neck pain: a randomized clinical trial

Objective: To compare the effects of an isolated application of cervical spine thrust joint manipulation vs. the application of cervical, cervico-thoracic junction and thoracic manipulation on neck pain, disability and cervical range of motion in chronic neck pain. Design: Randomized clinical trial. Setting: Clinical practice. Participants: Eighty-two patients (41 females) with chronic mechanical neck pain. Interventions: Patients were randomly assigned to a cervical spine manipulation group or a full manipulative group who received mid-cervical, cervico-thoracic and thoracic joint manipulations. Measurements: Neck pain intensity (11-point numeric pain rating scale), self-reported disability (Neck Disability Index) and cervical range of motion were collected at baseline and one week after the intervention by an assessor blinded to the allocation of the patients. Results: A significant Group * Time interaction for Neck Disability Index (P = 0.022), but not for neck pain (P = 0.612), was found: patients in the full manipulative group exhibited greater reduction in disability than those who received the cervical spine manipulation alone, whereas both groups experienced similar decreases in neck pain. Patients in both groups experienced similar increases in cervical range of motion (P > 0.4). No effect of gender was observed (P > 0.299). Conclusions: In patients with chronic mechanical neck pain, manipulation of the cervical and thoracic spine leads to a greater reduction in disability at one week than after manipulation of the cervical spine alone, whereas changes in pain and range of motion are not affected differently.
