Dry Needling Versus Manual Therapy for Patients With Mechanical Neck Pain: A Randomized Controlled Trial.

OBJECTIVE: To compare the short- and intermediate-term effects of dry needling to manual therapy on pain, disability, function, and patient-perceived improvement in patients with mechanical neck pain. DESIGN: A single (therapist) blinded randomized controlled trial. METHODS: Seventy-eight patients (mean ± SD age, 50.74 ± 13.81) were randomly assigned to one of the 2 groups: (1) dry needling and therapeutic exercises (DN + Exercises) and (2) manual therapy and therapeutic exercises (MT + Exercises). Both groups received 7 treatment sessions over a maximum of 6 weeks. Outcome measures, collected at baseline, 2 weeks, discharge (7th treatment session), and 3 months after discharge, were as follows: Neck Disability Index (NDI), numeric pain-rating scale (NPRS), Patient-Specific Functional Scale (PSFS), global rating of change (GROC), Fear-Avoidance Belief Questionnaire (FABQ), and Deep Neck Flexor Endurance Test (DNFET). Data were analyzed with mixed-model analysis of covariance (ANCOVA), using pretest scores as covariates, and a Mann-Whitney U test for GROC scores. RESULTS: The ANCOVA revealed significant group-by-time interaction for all variables. Significant between-group differences, favoring MT + Exercises, were observed at all 3 time points on the NDI (2 weeks: F1,446 = 172.68, P≤.001, [Formula: see text] = .27; discharge: F1,446 = 254.15, P≤.001, [Formula: see text] = .36; and 3 months: F1,446 = 339.40, P≤.001, [Formula: see text] = .43). Results for the MT + Exercises group exceeded recommended minimal clinically important difference for all variables, at all follow-up points. CONCLUSION: MT + Exercises was more effective, both in the short term and intermediate term, than DN + Exercises in reducing pain, disability, and improving function in patients with mechanical neck pain.

Pain Neuroscience Education in Elementary and Middle Schools.

PURPOSE: The purpose of this study was to deliver pain neuroscience education (PNE) to participants in grades 3 to 8 to determine whether participants in these grades had positive shifts in pain knowledge and beliefs. METHODS: Three hundred twenty participants, grades 3 to 8, received a 1-time, 30-minute PNE lecture. The Neurophysiology of Pain Questionnaire and the Health Care Provider's Pain and Impairment Relationship Scale were administered before and after the PNE lecture. RESULTS: All grades improved in pain knowledge and beliefs. Higher-grade school participants (sixth to eighth grades) experienced larger shifts in pain knowledge and attitudes and beliefs than lower-grade (third to fifth grades) participants. CONCLUSION: PNE results in changes in pain knowledge and beliefs in school participants in grades 3 to 8.

Differing Effects of Nociception and Pain Memory on Isometric Muscle Strength in Participants With and Without a History of Injury: A Quasi-Experimental Study.

OBJECTIVE: The goals of this study are to establish whether mechanical pressure pain, short-term memory recall of a painful stimulus, or long-term memory of a previous painful lower limb injury alters isometric muscle strength and whether there was a difference in responses between participants with and without a previous history of injury. DESIGN: Fifty-nine pain-free participants (29 with previous injury and 30 without) participated in this study. Tibialis anterior isometric muscle strength was compared pre- and post-noxious mechanical stimulus with instructions to recall pain (short- and long-term). RESULTS: Short- and long-term pain recall produced a significant reduction in muscle strength (short-term: F (1,57) = 160.472, P < 0.001; long-term: F (1,57) = 128.899, P < 0.001). A greater decrease was experienced with short- and long-term pain memory than exposure to mechanical pain (mechanical pain: -14.8% or -32.98 kg, 95% confidence interval [CI], -41.57 to -24.19; short-term: -24.1% or -52.70 kg, 95% CI = -60.98 to -44.34; long-term: -20.3% or -44.63 kg, 95% CI = -52.77 to -36.95). There was no significant difference in responses associated with an injury history. CONCLUSIONS: Findings suggest that recalled pain memory can impact motor responses and calls attention to the role of past injury history in the rehabilitation process.

Virtual McKenzie extension exercises for low back and leg pain: a prospective pilot exploratory case series.

INTRODUCTION: Current evidence supports the inclusion of directional preference exercises for a subgroup of patients with low back (LBP) and leg pain. Recent pain neuroscience strategies have suggested that cortical restructuring associated with movement activating the body map representation in the brain might account for the observed improvement with the directional preference approach. OBJECTIVES: To explore whether or not a motor imagery directional preference approach would result in any changes in patients with LBP and leg pain. METHODS: A consecutive convenience sample of patients with LBP and leg pain were recruited at two outpatient physical therapy clinics. Measurements of LBP, leg pain, fear-avoidance beliefs (FABQ), pain catastrophizing (PCS), active lumbar flexion, and straight leg raise (SLR) were compared before and immediately after a virtual (motor imagery) directional preference exercise. RESULTS: Statistically significant differences for LBP, FABQ, PCS, active lumbar flexion, and SLR were observed, but only SLR changes met or exceeded the minimally clinically important difference (MCID). CONCLUSIONS: A brief virtual motor imagery extension treatment yielded some immediate positive shifts in patients presenting to physical therapy with LBP and leg pain. Our results indicate that randomized comparison trials are needed to determine the effect of this intervention on the short- and longer-term outcomes in patients with LBP and leg pain.

Pain neuroscience education and graded exposure versus Pilates and postural education: A pilot study in an occupational context.

INTRODUCTION: Pain neuroscience education (PNE) and graded exposure have not been explored in occupational settings for low back pain (LBP). AIM: To pilot feasibility and assess preliminary effectiveness of PNE and graded exposure for LBP. METHODS: A pilot study where workers were randomized to either PNE and graded exposure or Pilates and postural education. Both interventions consisted of weekly individual face-to-face sessions for 8 weeks (a total of 8 sessions). The primary outcome was pain intensity. Secondary outcomes were disability, catastrophizing, fear-avoidance, sleep, endurance of back extensor muscles, and patient's perceived impression of change. RESULTS: Seventeen participants entered the PNE and graded exposure group and 20 the Pilates and postural education group. PNE and graded exposure were feasible to implement. Between-group comparisons suggest higher improvements in the PNE group for extensor muscle endurance (p < .001, η2p = .29), pain catastrophizing (p < .001; η2p = .56) and fear-avoidance related to physical activity (p < .001; η2p = .48) and work (p < .001; η2p = .47). In the PNE group, at least 13 (76.5%) participants reported being at least "moderately better" against 6 (30%) participants in the Pilates group. CONCLUSION: PNE and graded exposure can be successfully implemented in an occupational context and is potentially more beneficial than Pilates and postural education for extensor muscle endurance, catastrophizing, and fear avoidance and similarly as beneficial for pain intensity and disability. Further studies are needed to confirm these results.

Relationships Between the Physical Work Environment, Postures and Musculoskeletal Pain During COVID-19: A Survey of Frequent Computer Users.

OBJECTIVE: To understand the flexible work practices during the COVID-19 pandemic and their impact on work-related musculoskeletal disorders (MSDs) and depression in frequent computer users. METHODS: An e-survey determined the extent of workplace changes and MSD, and the relationships between them using descriptive-statistics and chi-squared tests. RESULTS: Of 700 who commenced the survey, 511 were analyzed. Since the pandemic commenced, 80% of respondents reported they were working more from home; and 89% reported some musculoskeletal pain. Compared with prepandemic, more people worked in nonergonomic environments, computer configurations and body postures. Work location was associated with upper back pain ( P = 0.011); body posture with headache ( P = 0.027) and low back pain ( P = 0.003). CONCLUSION: Nonergonomic work environments of frequent computer users during COVID-19 are related to having upper back pain, whereas nonergonomic postures are related to having headache and low back pain.

The clinical impact of pain neuroscience continuing education on physical therapy outcomes for patients with low back and neck pain.

OBJECTIVES: Research suggests that attendance by physical therapists at continuing education (CE) targeting the management of low back pain (LBP) and neck pain does not result in positive impacts on clinical outcomes. The aim of this study was to determine if therapists attending a self-paced 3-hour online Pain Neuroscience Education (PNE) program was associated with any observed changes to patient outcomes and also clinical practice. METHODS: Participants were 25 different physical therapists who treated 3,705 patients with low back pain (LBP) or neck pain before and after they had completed an online PNE CE course. Change in outcomes measures of pain and disability at discharge were compared for the patients treated before and after the therapist training. Clinical practice patterns of the therapists, including total treatment visits, duration of care, total units billed, average units billed per visit, percentage of 'active' billing units and percentage of 'active and manual' billing units, were also compared for the patient care episodes before and after the therapist training. RESULTS: There was no significant difference for change in pain scores at discharge for patients treated after therapist CE training compared to those treated before regardless of the condition (LBP or neck pain). However, patients with LBP who were treated after therapist CE training did report greater improvement in their disability scores. Also after CE training, for each episode of care, therapists tended to use less total visits, billed fewer units per visit, and billed a greater percentage of more 'active' and 'active and manual' billing units. DISCUSSION: Attending an online 3-hour CE course on PNE resulted in improved disability scores for patients with LBP, but not for those with neck pain. Changes in clinical behavior by the therapists included using less visits, billing fewer total units, and shifting to more active and manual therapy interventions. Further prospective studies with control groups should investigate the effect of therapist CE on patient outcomes and clinical practice.

Effectiveness of training physical therapists in pain neuroscience education for patients with chronic spine pain: a cluster-randomized trial.

ABSTRACT: Chronic spinal pain poses complex challenges for health care around the world and is in need of effective interventions. Pain neuroscience education (PNE) is a promising intervention hypothesized to improve pain and disability by changing individuals' beliefs, perceptions, and expectations about pain. Pain neuroscience education has shown promise in small, controlled trials when implemented in tightly controlled situations. Exploration of promising interventions through more pragmatic methodologies is a crucial but understudied step towards improving outcomes in routine clinical care. The purpose was to examine the impact of pragmatic PNE training on clinical outcomes in patients with chronic spine pain. The cluster-randomized clinical trial took place in 45 outpatient physical therapist (PT) clinics. Participants included 108 physical therapists (45 clinics and 16 clusters) and 319 patients. Clusters of PT clinics were randomly assigned to either receive training in PNE or no intervention and continue with usual care (UC). We found no significant differences between groups for our primary outcome at 12 weeks, Patient-Reported Outcomes Measurement Information System Physical Function computer adaptive test {mean difference = 1.05 (95% confidence interval [CI]: -0.73 to 2.83), P = 0.25}. The PNE group demonstrated significant greater improvements in pain self-efficacy at 12 and 2 weeks compared with no intervention (mean difference = 3.65 [95% CI: 0.00-7.29], P = 0.049 and = 3.08 [95% CI: 0.07 to -6.09], P = 0.045, respectively). However, a similar percentage of participants in both control (41.1%) and treatment (44.4%) groups reported having received the treatment per fidelity question (yes or no to pain discussed as a perceived threat) at 2 weeks. Pragmatic PT PNE training and delivery failed to produce significant functional changes in patients with chronic spinal pain but did produce significant improvement in pain self-efficacy over UC PT.

Thoracic thrust joint manipulation: An international survey of current practice and knowledge in IFOMPT member countries.

BACKGROUND: The perceived relative safety of thoracic thrust joint manipulation (TTJM) has contributed to a growth in evidence supporting use in practice. Yet adverse events (AE) have been documented following TTJM. Knowledge of current practice is therefore required to support further research. PURPOSE: To investigate TTJM knowledge and pre-TTJM examination across IFOMPT Member Organisations (MO) and Registered Interest Groups (RIG). METHODS: An e-survey was designed based on existing evidence and piloted. Eligibility criteria: physiotherapists from member countries of the International Federation of Orthopaedic Manipulative Physical Therapists (IFOMPT) who use TTJM. Recruitment was through IFOMPT networks (May 2018-March 2019). Data analyses included descriptive analyses and content analysis for free text data. RESULTS: Respondents (n = 363) from 20 countries. Pre-TTJM examination included patient history (22%, n = 81) and physical examination (69%, n = 248). Across presentations (>80% threshold of agreement) contraindications included osteomyelitis, fracture and metastatic disease. Spinal deformity, respiratory disease, serious joint disease and hypermobility achieved >60% agreement as precautions. Consent was obtained by 93% respondents (n = 250). Preferred technique was PA/AP thrust (61%, n = 144). Perception of primary effect was neurophysiological (52%, n = 134), biomechanical (42%, n = 109) and placebo (3%, n = 8). From those who reported AE (n = 100), these included fractures (36%, n = 42) and cord signs/symptoms (6%, n = 7). CONCLUSION: Pre-TTJM examination is common, although bias towards physical examination. Differential testing for upper versus lower thoracic spine is limited. Inconsistencies across knowledge of contraindications and precautions, and beliefs for biomechanical effect were found. Findings highlight the importance of high levels of clinical reasoning during patient history for TTJM.

Scapular movement impairments in individuals with subacromial pain syndrome based on scapular assistance test and scapula reposition test outcomes.

BACKGROUND: Individuals with subacromial pain present with a variety of contributing impairments related to the movement problem. The scapular assistance test (SAT) and scapula reposition test (SRT) are proposed to identify shoulder pain related to abnormal scapular movement or position. It remains unknown if scapular movement related impairments are present in those with positive tests. OBJECTIVES: To determine if scapular motion related impairments differ based on the result of the SAT or SRT in individuals with subacromial pain syndrome. DESIGN: Cross-sectional METHOD: Sixty individuals with subacromial pain syndrome were included. Prior to obtaining results of the SAT and SRT, a single examiner measured scapular upward rotation and posterior tilt active and passive motion, pectoralis minor length, and strength of the middle trapezius, lower trapezius, and serratus anterior. Dynamic scapular motion was qualitatively assessed with the Scapular Dyskinesis Test. The Mann-Whitney U test assessed for differences based on the outcome of the SAT and SRT. RESULTS: There was a significant difference (P = .023) in pectoralis minor length for the SAT. Participants with a positive SAT had decreased muscle length compared to those who tested negative. There were no significant differences in scapular motion or strength based on the result of either the SAT or SRT. CONCLUSIONS: A positive SAT was associated with greater pectoralis minor length impairment, but not muscle strength or mobility. The SRT did not identify greater impairments in any of the scapular movement related impairments assessed. Individuals may vary in contributing impairments related to SAT or SRT results.

Behavior Change Following Pain Neuroscience Education in Middle Schools: A Public Health Trial.

Chronic pain and the opioid epidemic need early, upstream interventions to aim at meaningful downstream behavioral changes. A recent pain neuroscience education (PNE) program was developed and tested for middle-school students to increase pain knowledge and promote healthier beliefs regarding pain. In this study, 668 seventh-grade middle-school students either received a PNE lecture (n = 220); usual curriculum school pain education (UC) (n = 198) or PNE followed by two booster (PNEBoost) sessions (n = 250). Prior to, immediately after and at six-month follow-up, pain knowledge and fear of physical activity was measured. Six months after the initial intervention school, physical education, recess and sports attendance/participation as well as healthcare choices for pain (doctor visits, rehabilitation visits and pain medication use) were measured. Students receiving PNEBoost used 30.6% less pain medication in the last 6 months compared to UC (p = 0.024). PNEBoost was superior to PNE for rehabilitation visits in students experiencing pain (p = 0.01) and UC for attending school in students who have experienced pain > 3 months (p = 0.004). In conclusion, PNEBoost yielded more positive behavioral results in middle school children at six-month follow-up than PNE and UC, including significant reduction in pain medication use.

Physician-Delivered Pain Neuroscience Education for Opioid Tapering: A Case Report.

We describe the case of a 75-year-old female with chronic low back pain (CLBP), on opioids for more than 15 years. She presented with an acute episode of nausea, vomiting, abdominal pain, and shortness of breath. After a complete work-up, it was concluded that her presenting symptoms were likely due to her high levels of CLBP and high dose opioids. At the time of intervention, her opioid dosage was between 50-90 MME (Morphine milligram equivalent) (Norco 8 × 7.5 mg/day + Fentanyl 12 mcg patch). She was subsequently seen by the physician for seven outpatient internal medicine appointments over nine months and received Pain Neuroscience Education (PNE) in conjunction with monitored tapering of opioids and other medication associated with her CLBP. This case report demonstrates how a physician might deliver PNE as a viable nonpharmacological treatment option for the tapering of long-term opioids for chronic pain.

Effectiveness of Cervical Spine High-Velocity, Low-Amplitude Thrust Added to Behavioral Education, Soft Tissue Mobilization, and Exercise for People With Temporomandibular Disorder With Myalgia: A Randomized Clinical Trial.

OBJECTIVE: To determine the immediate and short-term effects of adding cervical spine high-velocity, low-amplitude thrust (HVLAT) to behavioral education, soft tissue mobilization, and a home exercise program on pain and dysfunction for people with a primary complaint of temporomandibular disorder (TMD) with myalgia. DESIGN: Randomized clinical trial. METHODS: Fifty individuals with TMD were randomly assigned to receive cervical HVLAT or sham manipulation for 4 visits over 4 weeks. Participants in both groups received other treatments, including standardized behavioral education, soft tissue mobilization, and a home exercise program. Primary outcomes included maximal mouth opening, the numeric pain-rating scale, the Jaw Functional Limitation Scale (JFLS), the Tampa Scale of Kinesiophobia for TMD (TSK-TMD), and a global rating of change (GROC). Self-report and objective measurements were taken at baseline, immediately after initial treatment, and follow-ups of 1 week and 4 weeks. A 2-by-4 mixed-model analysis of variance was used, with intervention group as the between-subjects factor and time as the within-subject factor. Separate analyses of variance were performed for dependent variables, and the hypothesis of interest was the group-by-time interaction. RESULTS: There was no significant interaction for maximal mouth opening, the numeric pain-rating scale, or secondary measures. There were significant 2-way interactions for the JFLS (d = 0.60) and TSK-TMD (d = 0.80). The HVLAT group had lower fear at 4 weeks and improved jaw function earlier (1 week). The GROC favored the HVLAT group, with significant differences in successful outcomes noted immediately after baseline treatment (thrust, 6/25; sham, 0/25) and at 4 weeks (thrust, 17/25; sham, 10/25). CONCLUSION: Both groups improved over time; however, differences between groups were small. There were significant differences between groups for the JFLS, TSK-TMD, and GROC. The additive clinical effect of cervical HVLAT to standard care remains unclear for treating TMD. J Orthop Sports Phys Ther 2020;50(8):455-465. Epub 6 Jan 2020. doi:10.2519/jospt.2020.9175.

Pain neuroscience education: Which pain neuroscience education metaphor worked best?

BACKGROUND: The use of pain neuroscience education (PNE) has been shown to be effective in reducing pain, improving function and lowering fear and catastrophisation. Pain neuroscience education utilises various stories and metaphors to help patients reconceptualise their pain experience. To date no individualised study has looked at which stories and metaphors may be the most effective in achieving the positive outcomes found with the use of PNE. OBJECTIVES: This study examined patient responses to the usefulness of the various stories and metaphors used during PNE for patients who underwent surgery for lumbar radiculopathy. METHOD: Twenty-seven participants who received preoperative PNE from a previous randomised control trial (RCT) were surveyed 1-year post-education utilising a 5-point Likert scale (0 - 'do not remember', 4 - 'very helpful') on the usefulness of the various stories and metaphors used during the PNE session. Participant demographics and outcomes data (pain intensity, function and pain knowledge) were utilised from the previous RCT for analysis and correlations. RESULTS: Nineteen surveys were returned for a response rate of 70%. No story or metaphor mean was below 2 - 'neutral', lowest mean at 2.53; 6 of the 11 stories or metaphors scored a mean above 3 - 'helpful'. CONCLUSION: No individual story or metaphor stood out as being predominately important in being helpful in the recovery process through the use of PNE. CLINICAL IMPLICATIONS: The overall messages of reconceptualising pain during PNE may be more important than any individual story or metaphor.

A controlled clinical trial of preoperative pain neuroscience education for patients about to undergo total knee arthroplasty.

OBJECTIVE: The aim of this study was to determine if a preoperative pain neuroscience education program would result in superior outcomes compared to usual preoperative education for total knee arthroplasty. DESIGN: Controlled clinical trial with alternating allocation. SETTING: Community-based hospital. SUBJECTS: Consecutive sample of 120 patients scheduled for total knee arthroplasty. INTERVENTION: Traditional hospital preoperative total knee arthroplasty education program on its own, or with an additional 30-minute group pain neuroscience education session. MAIN MEASURES: Primary outcomes were measurements at one, three, and six months for pain, function, fear of movement, and pain catastrophization. We also compared opioid usage, healthcare expenses, and patient satisfaction between groups. RESULTS: There were no statistically significant differences in any outcome measures between the two groups over time, except for patient satisfaction. Those in the experimental group had more agreement with statements about "preparation for surgery" (P = .038), "would do again" (P = .032), and "met expectations" (P = .033) compared to those in the control group averaged over the three measurement times. Patients improved in several outcome measures over time regardless of group assignment, with a 34% improvement in pain, 36% improvement in function, 16% improvement in fear of movement, and 23% improvement in pain catastrophization scores. CONCLUSION: Adding a brief 30-minute pain neuroscience education session to a traditional preoperative total knee arthroplasty education program did not result in any significant improvements, except patient satisfaction.

Immediate effect of pain neuroscience education for recent onset low back pain: an exploratory single arm trial.

Study Design: A prospective, single-arm, pre-postintervention study.Objective: To determine the preliminary usefulness of providing pain neuroscience education (PNE) on improving pain and movement in patients presenting with non-chronic mechanical low back pain (LBP).Background: PNE has been shown to be an effective intervention for the treatment of chronic LBP but its usefulness in patients with non-chronic LBP has not been examined.Methods: A single group cohort pilot study was conducted. Eighty consecutive patients with LBP < 3 months completed a demographics questionnaire, leg and LBP rating (Numeric Pain Rating Scale - NPRS), disability (Oswestry Disability Index), fear-avoidance (Fear-Avoidance Beliefs Questionnaire), pain catastrophizing (Pain Catastrophizing Scale), central sensitization (Central Sensitization Inventory), pain knowledge (Revised Neurophysiology of Pain Questionnaire), risk assessment (Keele STarT Back Screening Tool), active trunk flexion and straight leg raise (SLR). Patients received a 15-minute verbal, one-on-one PNE session, followed by repeat measurement of LBP and leg pain (NPRS), trunk flexion and SLR.Results: Immediately after intervention, LBP and leg pain improved significantly (p < 0.001), but the mean change did not exceed minimal clinically important difference (MCID) of 2.0. Active trunk flexion significantly improved (p < 0.001), with the mean improvement (4.7 cm) exceeding minimal detectible change (MDC). SLR improved significantly (p = 0.002), but mean change did not exceed MDC.Conclusions: PNE may be an interesting option in the treatment of patients with non-chronic mechanical LBP. The present pilot study provides the rationale for studying larger groups of patients in controlled studies over longer periods of time.

The Comparative Effects of Upper Thoracic Spine Thrust Manipulation Techniques in Individuals With Subacromial Pain Syndrome: A Randomized Clinical Trial.

BACKGROUND: Subacromial pain syndrome (SPS) accounts for as much as 44% of shoulder pain encountered by physical therapists. Thoracic spine thrust manipulation (TSTM) is effective in the short term for improving pain and function in individuals with SPS, but its mechanisms remain elusive. Furthermore, it is unknown whether individuals with SPS respond differently based on the TSTM technique received. OBJECTIVES: To compare the immediate effects of a supine TSTM, seated TSTM, and sham manipulation on the primary outcomes of self-reported pain, function, and satisfaction and secondary biomechanical impairments examined in individuals with SPS. METHODS: Participants in this randomized clinical trial were randomized to receive a seated TSTM (n = 20), supine TSTM (n = 20), or sham manipulation (n = 20). The primary outcomes of self-reported pain, function, and satisfaction were measured via the Penn Shoulder Score. Secondary outcomes were changes in scapular upward rotation and posterior tilt; peak force generated in tests for the middle trapezius, lower trapezius, and serratus anterior; and pectoralis minor muscle length. Impairment measures were immediately reassessed, and the Penn Shoulder Score was reassessed after 48 hours. RESULTS: There were no significant between-group differences in immediate or short-term follow-up outcomes. CONCLUSION: Two TSTM techniques resulted in no differences in pain, satisfaction, and function when compared to a sham manipulation. Thoracic spine thrust manipulation did not have an immediate effect on the scapular impairments examined. LEVEL OF EVIDENCE: Therapy, level 1. J Orthop Sports Phys Ther 2019;49(10):716-724. Epub 12 Mar 2019. doi:10.2519/jospt.2019.8484.

Immediate preoperative outcomes of pain neuroscience education for patients undergoing total knee arthroplasty: A case series.

BACKGROUND: Standard preoperative education for total knee arthroplasty (TKA) has been shown to have no effect on postoperative outcomes. This may be because such education programs fail to educate patients about pain. Pain neuroscience education (PNE) focuses on teaching people more about pain from a neurobiological and neurophysiological perspective. DESIGN AND SETTING: Case Series. AIM: To determine the immediate effects, if any, of providing PNE before TKA surgery on patient self-report measures. PARTICIPANTS: Twelve patients (female = 10) prior to TKA for knee osteoarthritis (OA). INTERVENTION: Preoperative educational session by a physical therapist on the neuroscience of pain, accompanied by an evidence-based booklet. MAIN OUTCOME MEASURES: Comparison of pre- and post-PNE self-report measures on knee pain (NPRS), Pain Catastrophization Scale (PCS), fear of movement (TSK), and beliefs about TKA; as well as three physical performance measures - knee flexion active range of motion, 40 m self-paced walk, and pressure pain threshold (PPT). RESULTS: Immediately following the PNE, patients had statistically significant lower TSK scores, increased PPT, and improved beliefs about their upcoming surgery. There were no significant changes in knee pain, function, or flexion active range of motion. CONCLUSIONS: Results appear to suggest that immediately after PNE, patients scheduled for TKA had statistically significant changes in fear of movement, decreased sensitivity to pain and positive shifts in their beliefs about their future knee surgery. Larger trials with control/comparison groups are warranted to determine the true effects of preoperative PNE for patients about to undergo TKA.
