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.

The Effects of Thrust Joint Manipulation on the Resting and Contraction Thickness of Transversus Abdominis in Patients With Low Back Pain: A Randomized Control Trial.

OBJECTIVE: To investigate the immediate changes in resting and contracted thickness of the transversus abdominis (TrA) muscle after application of thrust joint manipulation (TJM) vs sham manipulation in participants with low back pain. METHODS: A pretest-posttest randomized controlled trial design was performed. Consecutive subjects satisfying eligibility criteria completed patient-report outcome baseline measures, pretreatment rehabilitative ultrasound imaging (RUSI) measurements, followed by the randomly assigned intervention then, post-treatment RUSI measurements, and post-treatment & final patient-reported outcome measures. To compare the outcomes of TJM and sham manipulation on the TrA muscle thickness, a 2-by-2 analysis of variance (treatment [TJM and sham manipulation]) by time (pretreatment and post-treatment) was completed for both the TrA muscle thickness at rest and muscle thickness during contraction. Descriptive statistics including independent-sample t tests for continuous variables and χ2 tests for categorical variables were used to analyze differences in patient-reported outcome measures between groups. RESULTS: Sixty-seven eligible participants agreed to participate. No significant interactions were identified for either muscle thickness at rest or contraction. CONCLUSION: This study did not support the hypothesis that manipulation would result in greater changes in TrA thickness at rest or during contraction in participants with low back pain. Based on prior research that identified subgroups of participants likely to respond to manipulation, future research should include participants more likely to respond favorably to TJM. This study was a priori registered with clinicaltrails.gov (NCT02558855).

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.

Measurement of anterior translation of the mandibular condyle using sonography.

[Purpose] To establish a standardized sonographic approach to quantify anterior translation of the mandibular condyle during mouth opening by examining the reliability of image acquisition and processing, and to understand how anterior condylar translation contributes to mouth opening. [Participants and Methods] Twenty-eight participants without temporomandibular disorder (TMD) participated. During day 1 of data collection, all participants performed maximal mouth opening while an examiner recorded anterior condylar translation using sonography. The mouth opening range of motion was also obtained. On day 2 of data collection, the same procedure was performed on 6 participants that participated in day 1 of data collection. To establish reliability of image processing, 3 examiners measured condylar translations on 2 separate days. To determine reliability of image acquisition, images obtained from 2 days of data collection were analyzed. [Results] Excellent intra-class correlation coefficients (ICCs) and small standard errors of measurement (SEMs) for image acquisition and processing were shown. A significant, linear model was found to describe the relationship between condylar anterior translations and mouth opening. [Conclusion] Anterior condylar translation during mouth opening can be reliably measured using sonography. The linear relation between condylar motion and mouth opening can be used to guide clinical practices.

Knowledge and pre-thoracic spinal thrust manipulation examination: a survey of current practice in the UK.

OBJECTIVES: The perceived relative safety of thoracic thrust joint manipulation (TTJM) has contributed to evidence supporting its use. Yet, TTJM is not without risk, where transient side effects (SE) and severe adverse events (AE) have been documented. With evidence supporting the importance of prethrust examination in reducing AE in other spinal regions this study investigated TTJM knowledge and pre-TTJM examination. Method: An e-survey, informed by existing evidence and expertise was designed and piloted. Eligibility criteria: UK-trained physiotherapists who use TTJM. Recruitment via professional networks and social media from December 2016 to February 2017. Data analysis included descriptive analyses (means, standard deviation and frequencies/central tendencies), and content analysis (themes and frequencies) for free text data. Results: From 306 responses, the sample comprised 146 (53%) males, mean (SD) age 36.37(8.68) years, with 12.88(8.67) years in practice, 11.07(8.14) years specialization, working in National Health Service/private practice (81%) and performing 0-5 TTJM/week (86%). EXAMINATION: 40% (n = 83) utilized pre-TTJM examination with 45% (n = 139) adapting the examination for different regions. Technique selection and effect: preferred technique was prone rotational TTJM (67%). Perception of the primary underlying effect was neurophysiological (54%), biomechanical (45%) or placebo (1%). Knowledge: Levels of agreement were found for contraindications (85%), precautions (75%), and red flags (86%) with more variability for risks including AE and SE (61%). DISCUSSION: UK physiotherapists demonstrated good knowledge and agreement of contraindications, precautions, and red flags to TTJM. With <50% respondents utilizing pre-TTJM examination, variable knowledge of TTJM risks, and therapeutic effects of TTJM further research is required.

Sham Surgery in Orthopedics: A Systematic Review of the Literature.

Objective: To evaluate the evidence for the effectiveness of sham surgery in orthopedics by conducting a systematic review of literature. Methods: 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. All randomized controlled trials comparing surgery versus sham surgery in orthopedics were included. Data were extracted and methodological quality was assessed by two reviewers using the Critical Review Form-Quantitative Studies. Levels of scientific evidence, based on the direction of outcomes of the trials, were established following the Australian National Health and Medical Research Council (NHMRC) Hierarchy of Evidence (Australian National Health and Medical Research Council, 1999). Results: This review includes six randomized controlled trials (RCTs) involving 277 subjects. All six studies were rated as very good on methodological quality. 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, demonstrated that sham surgery in orthopedics was as effective as actual surgery in reducing pain and improving disability. Conclusions: This review suggests that sham surgery has shown to be just as effective as actual surgery in reducing pain and disability; however, care should be taken to generalize findings because of the limited number of studies.

Immediate Effects of Mirror Therapy in Patients With Shoulder Pain and Decreased Range of Motion.

OBJECTIVE: To determine the effects of a brief single component of the graded motor imagery (GMI) sequence (mirror therapy) on active range of motion (AROM), pain, fear avoidance, and pain catastrophization in patients with shoulder pain. DESIGN: Single-blind case series. SETTING: Three outpatient physical therapy clinics. PARTICIPANTS: Patients with shoulder pain and limited AROM (N=69). INTERVENTION: Patients moved their unaffected shoulder through comfortable AROM in front of a mirror so that it appeared that they were moving their affected shoulder. MAIN OUTCOME MEASURES: We measured pain, pain catastrophization, fear avoidance, and AROM in 69 consecutive patients with shoulder pain and limited AROM before and immediately after mirror therapy. RESULTS: There were significant differences in self-reported pain (P=.014), pain catastrophization (P<.001), and the Tampa Scale of Kinesiophobia (P=.012) immediately after mirror therapy; however, the means did not meet or exceed the minimal detectable change (MDC) for each outcome measure. There was a significant increase (mean, 14.5°) in affected shoulder flexion AROM immediately postmirror therapy (P<.001), which exceeded the MDC of 8°. CONCLUSIONS: A brief mirror therapy intervention can result in statistically significant improvements in pain, pain catastrophization, fear avoidance, and shoulder flexion AROM in patients presenting with shoulder pain with limited AROM. The immediate changes may allow a quicker transition to multimodal treatment, including manual therapy and exercise in these patients. Further studies, including randomized controlled trials, are needed to investigate these findings and determine longer-term effects.

Immediate Changes in Resting and Contracted Thickness of Transversus Abdominis After Dry Needling of Lumbar Multifidus in Healthy Participants: A Randomized Controlled Crossover Trial.

OBJECTIVE: The purpose of this study was to investigate changes in resting and/or contraction thickness of the transversus abdominis (TrA) muscle after dry needling (DN) of the lumbar multifidus (LM) in asymptomatic participants. METHODS: A randomized controlled laboratory trial with crossover design was performed. Forty-seven healthy individuals who had not experienced low back pain in the previous 6 months were randomly assigned to receive DN to the LM or a sham-DN intervention. Participants received both interventions separated at least 7 days apart. They were instructed on how to perform a concentric contraction of TrA. Resting and contraction thicknesses of the TrA were obtained through real-time ultrasound measurements before and immediately after each intervention by an assessor blinded to the intervention received. Data from 4 individuals had to be excluded because of poor image quality. RESULTS: Two-way analysis of variance revealed a significant contraction with treatment interaction (F[1,42] = 11.489; P = .002). Simple main effects using paired-samples t tests and a Bonferroni post hoc analysis revealed differences in contracted states of the TrA for DN vs sham-DN (P = .009) and between contracted and resting states for the DN group (P = .001): after DN, TrA thickness at rest exhibited a mean decrease of 0.03 cm and a mean increase of 0.05 cm during contraction. CONCLUSION: This study suggests that application of DN to LM was accompanied by a decreased resting thickness and an increased contraction thickness of the TrA in asymptomatic participants.

An abbreviated therapeutic neuroscience education session improves pain knowledge in first-year physical therapy students but does not change attitudes or beliefs.

OBJECTIVE: To determine if a 3-hour therapeutic neuroscience education session alters physical therapy student's knowledge of pain and effects their attitudes and beliefs regarding treating chronic pain. METHODS: Seventy-seven entry-level doctoral physical therapy students participated in the study. Following consent, demographic data were obtained and then the subjects completed the Neuroscience of Pain Questionnaire, the Health Care Provider's Pain and Impairment Relationship Scale and an additional questionnaire designed by the researchers. The subjects then received a 3-hour educational session developed by the researchers, focusing on the neurobiology and physiology of pain. The questionnaires were re-administered immediately after the educational session and at 6 months post-education. RESULTS: Seventy-seven subjects (mean age = 24.7 years, 57.1% female and 81.8% white) completed the questionnaires pre- and post-educational session with 75 completing the questionnaires at 6 months. To assess the effect of the education on the scores of the questionnaires, a repeated measures ANOVA was conducted. Students demonstrated significantly higher scores on the neuroscience of pain questionnaire (p < 0.001) with no significant effect found on the attitudes and beliefs questionnaire at any of the time points. There were significant differences found on some of the individual questions that were part of the additional questionnaire. DISCUSSION: An educational session on the neuroscience of pain is beneficial for educating entry-level doctoral physical therapy students immediately post-education and at 6 months. This educational session had no effect on the student's attitudes and beliefs regarding treating the chronic pain population. There were additional significant findings regarding individual questions posed to the subjects.

A clinical perspective on a pain neuroscience education approach to manual therapy.

In recent years, there has been an increased interest in pain neuroscience education (PNE) in physical therapy. There is growing evidence for the efficacy of PNE to decrease pain, disability, fear-avoidance, pain catastrophization, limited movement, and health care utilization in people struggling with pain. PNE teaches people in pain more about the biology and physiology of their pain experience including processes such as central sensitization, peripheral sensitization, allodynia, inhibition, facilitation, neuroplasticity and more. PNE's neurobiological model often finds itself at odds with traditional biomedical models used in physical therapy. Traditional biomedical models, focusing on anatomy, pathoanatomy, and biomechanics have been shown to have limited efficacy in helping people understand their pain, especially chronic pain, and may in fact even increase a person's pain experience by increasing fear-avoidance and pain catastrophization. An area of physical therapy where the biomedical model is used a lot is manual therapy. This contrast between PNE and manual therapy has seemingly polarized followers from each approach to see PNE as a 'hands-off' approach even having clinicians categorize patients as either in need of receiving PNE (with no hands-on), or hands-on with no PNE. In this paper, we explore the notion of PNE and manual therapy co-existing. PNE research has shown to have immediate effects of various clinical signs and symptoms associated with central sensitization. Using a model of sensitization (innocuous, noxious, and allodynia), we argue that PNE can be used in a manual therapy model, especially treating someone where the nervous system has become increasingly hypervigilant. Level of Evidence: VII.

Thrust joint manipulation utilization by U.S. physical therapists.

STUDY DESIGN: Online survey study. OBJECTIVE: To determine physical therapists' utilization of thrust joint manipulation (TJM) and their comfort level in using TJM between the cervical, thoracic, and lumbar regions of the spine. We hypothesized that physical therapists who use TJM would report regular use and comfort providing it to the thoracic and lumbar spines, but not so much for the cervical spine. BACKGROUND: Recent surveys of first professional physical therapy degree programs have found that TJM to the cervical spine is not taught to the same degree as to the thoracic and lumbar spines. METHODS: We developed a survey to capture the required information and had a Delphi panel of 15 expert orthopedic physical therapists review it and provide constructive feedback. A revised version of the survey was sent to the same Delphi panel and consensus was obtained on the final survey instrument. The revised survey was made available to any licensed physical therapists in the U.S.A. using an online survey system, from October 2014 through June 2015. RESULTS: Of 1014 responses collected, 1000 completed surveys were included for analysis. There were 478 (48%) males; the mean age of respondents was 39.7 ± 10.81 years (range 24-92); and mean years of clinical experience was 13.6 ± 10.62. A majority of respondents felt that TJM was safe and effective when applied to lumbar (90.5%) and thoracic (91.1%) spines; however, a smaller percentage (68.9%) felt that about the cervical spine. More therapists reported they would perform additional screening prior to providing TJM to the cervical spine than they would for the lumbar and thoracic spines. Therapists agreed they were less likely to provide and feel comfortable with TJM in the cervical spine compared to the thoracic and lumbar spines. Finally, therapists who are male; practice in orthopedic spine setting; are aware of manipulation clinical prediction rules; and have manual therapy certification, are more likely to use TJM and be comfortable with it in all three regions. CONCLUSION: Results indicate that respondents do not believe TJM for the cervical spine to be as safe and efficacious as that for the lumbar and thoracic spines. Further, they are more likely to perform additional screening, abstain from and do not feel comfortable performing TJM for the cervical spine. CLINICAL RELEVANCE: Our research reveals there is a discrepancy between utilization of TJM at different spinal levels. This research provides an opportunity to address variability in clinical practice among physical therapists utilizing TJM.

A descriptive study of the utilization of physical therapy for postoperative rehabilitation in patients undergoing surgery for lumbar radiculopathy.

PURPOSE: To determine the referral patterns, utilization and indications for postoperative physical therapy (PT) for lumbar radiculopathy. At least 50 % of patients following lumbar surgery (LS) for radiculopathy are referred for PT to address postoperative pain and disability. Very little is known regarding factors following LS that predict referral to PT, patient perceptions, satisfaction of postoperative PT and predictors of success for PT following LS for radiculopathy. METHODS: Sixty-five patients who underwent LS for radiculopathy completed outcome measures on pain and disability prior to, and 1, 3, 6 and 12 months after LS. They also completed a questionnaire regarding postoperative PT at the 12-month follow-up. RESULTS: The majority of patients (59.32 %) attended PT after LS for an average of 14 visits and rated PT favorably. Forty-five percent of the patients who did not attend PT after LS were of the opinion that they would have benefitted from PT after LS, and 62.5 % of these patients reported the surgeon not discussing postoperative PT after LS. Patients with longer duration of symptoms prior to surgery, with greater leg pain scores 1 month after surgery, and who did not feel as well prepared for surgery at the 1 year follow-up were more likely to receive PT, but this did not result in significantly better outcomes on any measure at any follow-up period and did not predict attendance in PT after LS. CONCLUSION: There is a need to determine if a subgroup of patients following LS exists who will respond favorably to postoperative PT.

The immediate effects of soft tissue mobilization versus therapeutic ultrasound for patients with neck and arm pain with evidence of neural mechanosensitivity: a randomized clinical trial.

STUDY DESIGN: Randomized clinical trial. OBJECTIVES: To investigate the immediate effects of soft tissue mobilization (STM) versus therapeutic ultrasound (US) in patients with neck and arm pain who demonstrate neural mechanical sensitivity. BACKGROUND: While experts have suggested that individuals with neck and arm pain associated with neural tissue mechanical sensitivity may benefit from STM, there has been little research to investigate this hypothesis. METHODS: Twenty-three patients with neck and arm pain and a positive upper limb neurodynamic test (ULNT) were randomly assigned to receive STM or therapeutic US during a single session. Outcome measures were collected immediately before and after treatment, and at 2-4 day follow-up. Primary outcomes were the Global Rating of Change (GROC), range of motion (ROM) during the ULNT, and pain rating during the ULNT. Secondary measures included the Neck Disability Index (NDI), Patient-Specific Functional Scale (PSFS), Numeric Pain Rating Scale (NPRS), and active range of shoulder abduction motion combined with the wrist neutral or wrist extension. RESULTS: A greater proportion of patients in the STM group reported a significant improvement on the GROC immediately after treatment (P = 0·003, STM = 75%, US = 9%), and at 2-4 day follow-up (P = 0·027, STM = 58%, US = 9%). Patients who received STM demonstrated greater improvements in ROM during ULNT (P = 0·026), PSFS (P = 0·007), and shoulder active ROM combined with wrist extension (P = 0·028). Improvements in Numeric Pain Rating Scale and pain during the ULNT were observed only in the STM group. There was no difference between groups for the NDI or shoulder abduction ROM with wrist neutral. CONCLUSION: Patients with neck and arm pain demonstrated greater improvements in ULNT ROM, GROC, and PSFS, and pain following STM than after receiving therapeutic US. LEVEL OF EVIDENCE: Therapy, level 1b.

Safety of thrust joint manipulation in the thoracic spine: a systematic review.

BACKGROUND: There appears to be very little in the research literature on the safety of thrust joint manipulation (TJM) when applied to the thoracic spine. PURPOSE: To retrospectively analyze all available documented case reports in the literature describing patients who had experienced severe adverse events (AE) after receiving TJM to their thoracic spine. DATA SOURCES: Case reports published in peer reviewed journals were searched in Medline (using Ovid Technologies, Inc.), Science Direct, Web of Science, PEDro (Physiotherapy Evidence Database), Index of Chiropractic literature, AMED (Allied and Alternative Medicine Database), PubMed and the Cumulative Index to Nursing and Allied Health (CINHAL) from January 1950 to February 2015. STUDY SELECTION: Case reports were included if they: (1) were peer-reviewed; (2) were published between 1950 and 2015; (3) provided case reports or case series; and (4) had TJM as an intervention. Articles were excluded if: (1) the AE occurred without TJM (e.g. spontaneous); (2) the article was a systematic or literature review; or (3) it was written in a language other than English or Spanish. DATA EXTRACTION: Data extracted from each case report included: gender; age; who performed the TJM and why; presence of contraindications; the number of manipulation interventions performed; initial symptoms experienced after the TJM; as well as type of severe AE that resulted. RESULTS: Ten cases, reported in 7 case reports, were reviewed. Cases involved females (8) more than males (2), with mean age being 43.5 years (SD=18.73, Range = 17 -71). The most frequent AE reported was injury (mechanical or vascular) to the spinal cord (7/10), with pneumothorax and hematothorax (2/10) and CSF leak secondary to dural sleeve injury (1/10). LIMITATIONS: There were only a small number of case reports published in the literature and there may have been discrepancies between what was reported and what actually occurred, since physicians dealing with the effects of the AE, rather than the clinician performing the TJM, published the cases. CONCLUSIONS: Serious AE do occur in the thoracic spine, most commonly, trauma to the spinal cord, followed by pneumothorax. This suggests that excessive peak forces may have been applied to thoracic spine, and it should serve as a cautionary note for clinicians to decrease these peak forces.

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 for Acute Pain.

In musculoskeletal and sports medicine, pain has traditionally been linked to tissue injury, often assuming a linear correlation between tissue damage and pain intensity. However, modern pain science has illuminated the complexity of the human pain experience, incorporating psychosocial elements, nervous system sensitization, immune responses, and structural changes in the brain as factors. This contemporary understanding of pain has proven highly beneficial for both clinicians treating individuals in pain and those experiencing pain. Pain neuroscience education (PNE) provides individuals in pain with an understanding of the underlying neurobiology and neurophysiology of their pain experience, which has been shown to result in decreased self-reported pain, reduced disability, the alleviation of fear and fear-avoidance behaviors, diminished pain catastrophizing, and improved movement. Currently, research on PNE predominantly focuses on interventions with individuals with persistent or chronic pain conditions. However, those who experience acute, sub-acute, and perioperative pain also have the potential for elevated levels of fear, fear-avoidance, and pain catastrophizing, indicating potential benefits from PNE. This invited commentary seeks to inform readers about the latest advancements in pain science and propose a conceptual model for delivering PNE in acute pain experiences. Level of Evidence: 5.

The correlation of trust as part of the therapeutic alliance in physical therapy and their relation to outcomes for patients with chronic low back pain.

BACKGROUND: Previous qualitative research has listed trust as a component of the therapeutic alliance in physical therapy. OBJECTIVE: Quantitatively correlate trust and therapeutic alliance in physical therapy care for patients with chronic low back pain. The secondary aim was to investigate the relation of trust and therapeutic alliance with outcomes over the course of treatment. METHODS: The Primary Care Assessment Survey was used to measure trust and the Working Alliance Inventory-Short Revised tool measured therapeutic alliance. The patient recorded these measures after the initial visit and at discharge. Self-report patient outcome measures for pain, function, and global rating of change were also measured at the same time points. RESULTS: A strong correlation (rs = 0.747 and rs = 0.801) was found between trust scores and therapeutic alliance measures post-initial visit and at discharge, respectively. In addition, there were moderate to strong correlations between trust and therapeutic alliance scores with the various improved outcome measures of pain, function, and global rating of change. CONCLUSION: There appears to be a connection between trust and therapeutic alliance along with improved patient outcomes related to higher trust and therapeutic alliance scores in a cohort with chronic low back pain.

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.

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.

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.
