Does having an external focus in immersive virtual reality increase range of motion in people with neck pain?

BACKGROUND: When instructing exercises to improve Range of Motion (ROM), clinicians often create an internal focus of attention, while motor performance may improve more when using an external focus. OBJECTIVES: Using Virtual Reality (VR), we investigated the effect of tasks with an internal and external focus on maximal ROM in people with neck pain and explored whether this effect was associated with fear of movement. METHOD: In this cross-over experimental design study, the cervical ROM of 54 participants was measured while performing a target-seeking exercise in a VR-environment (external focus task) and during three maximal rotation and flexion-extension movements with the VR-headset on, without signal (internal focus task). The main statistical analysis included two dependent T-tests. Pearson correlation coefficients were calculated to investigate whether the differences in ROM in both conditions were correlated to fear of movement. RESULTS: Maximal neck rotation was larger in the external focus condition than in the internal focus condition (mean difference: 26.4°, 95% CI [20.6, 32.3]; p < 0.001, d = 1.24). However, there was a difference favouring the internal focus condition for flexion-extension (mean difference: 8.2°, 95% CI [-14.9, -1.5]; p = 0.018, d = 0.33). The variability in ROM was not explained by variability in fear of movement (for all correlations p ≥ 0.197). CONCLUSION: An external focus resulted in a larger range of rotation, but our flexion-extension findings suggest that the task has to be specific to elicit such an effect. Further research, using a task that sufficiently elicits movement in all directions, is needed to determine the value of an external focus during exercise.

Online Exercise Programs for Chronic Nonspecific Neck Pain: A Randomized Controlled Trial Reveals Comparable Effects of Global, Local, and Combined Approaches.

OBJECTIVE: Specific neck exercises are recommended in the rehabilitation of chronic nonspecific neck pain. They are unfortunately often accompanied by acute pain flare-ups. Global exercises might be a beneficial addition, as they activate endogenous analgesia without overloading painful structures. However, it is still unclear which type of exercise is most effective. This randomized controlled trial was done to evaluate the effect of an online blended program of global and specific neck exercises, compared to programs including only 1 of both types of exercise. METHODS: Forty-eight patients with chronic nonspecific neck pain were randomized into 3 groups. Online questionnaires were collected at baseline, at midtreatment, immediately after treatment, and at the 3-month follow-up. Quantitative sensory testing and actigraphy were assessed at baseline and after treatment. Linear mixed-model analyses were performed to evaluate treatment effects within and between groups. Neck pain-related disability after treatment was considered the primary outcome. RESULTS: No time × treatment interaction effects were found. All groups improved in neck pain-related disability, pain intensity, self-reported symptoms of central sensitization, local pain sensitivity, physical activity, and pain medication use. No effects were found on quality of life, sleep quality, depression, anxiety, stress, widespread pain sensitivity, health economics, or actigraphy measurements. A higher global perceived effect was reported after performing the blended program, compared to the other groups. CONCLUSION: A blended exercise program was not superior to the stand-alone programs in reducing disability. Nevertheless, the global perceived effect of this type of exercise was higher. Future research necessitates larger sample sizes to adequately explore the optimal type of exercise for patients with chronic nonspecific neck pain. IMPACT: Exercise therapy should be an important part of the rehabilitation of patients with chronic nonspecific neck pain, regardless of the type of exercise.

Comparing physical therapy students' attitudes and beliefs regarding chronic low back pain and knee osteoarthritis: an international multi-institutional comparison between 2013 and 2020 academic years.

BACKGROUND: In 2013, physical therapy students demonstrated low guideline-adherent recommendations regarding chronic low back pain (CLBP) for spinal pathology, activity, and work. OBJECTIVES: To assess the differences in physical therapy students' attitudes, beliefs, and adherence to guideline recommendations regarding CLBP and knee osteoarthritis between 2013 and 2020. METHODS: In 2013 and 2020, second and fourth-year physical therapy students were recruited from 6 Belgian and 2 Dutch institutions. Attitudes and beliefs regarding CLBP and knee OA were evaluated using the Pain Attitudes and Beliefs Scale for Physiotherapists (PABS-PT), the Health Care Providers' Pain and Impairment Relationship Scale (HC-PAIRS), and a questionnaire regarding therapeutic exercise and knee osteoarthritis. A clinical vignette was used to measure guideline-adherent recommendations regarding spinal pathology, activity, and work. RESULTS: In 2013, 927 second-year and 695 fourth-year students; in 2020, 695 second-year and 489 fourth-year students; were recruited to participate in the study. Compared to 2013, students had less biomedical and stronger biopsychosocial attitudes and beliefs regarding CLBP, more guideline-adherent recommendations for activity, and more biopsychosocial beliefs regarding the benefits of exercise for patients with knee osteoarthritis in both the second and fourth year. Only fourth-year students in 2020 scored significantly better on HC-PAIRS and guideline-adherent recommendation relating to spinal pathology. No differences were found regarding work recommendations. CONCLUSIONS: Between 2013 and 2020, physical therapy students made a positive shift towards a more biopsychosocial approach to CLBP and knee osteoarthritis management. Guideline-adherent recommendations for CLBP concerning activity improved, however, concerning work and spinal pathology, it remained low.

Nociceptive, neuropathic, or nociplastic low back pain? The low back pain phenotyping (BACPAP) consortium's international and multidisciplinary consensus recommendations.

The potential to classify low back pain as being characterised by dominant nociceptive, neuropathic, or nociplastic mechanisms is a clinically relevant issue. Preliminary evidence suggests that these low back pain phenotypes might respond differently to treatments; however, more research must be done before making specific recommendations. Accordingly, the low back pain phenotyping (BACPAP) consortium was established as a group of 36 clinicians and researchers from 13 countries (five continents) and 29 institutions, to apply a modified Nominal Group Technique methodology to develop international and multidisciplinary consensus recommendations to provide guidance for identifying the dominant pain phenotype in patients with low back pain, and potentially adapt pain management strategies. The BACPAP consortium's recommendations are also intended to provide direction for future clinical research by building on the established clinical criteria for neuropathic and nociplastic pain. The BACPAP consortium's consensus recommendations are a necessary early step in the process to determine if personalised pain medicine based on pain phenotypes is feasible for low back pain management. Therefore, these recommendations are not ready to be implemented in clinical practice until additional evidence is generated that is specific to these low back pain phenotypes.

Illness perceptions in people with chronic and disabling non-specific neck pain seeking primary healthcare: a qualitative study.

BACKGROUND: Illness perceptions can affect the way people with musculoskeletal pain emotionally and behaviorally cope with their health condition. Understanding patients illness perceptions may help facilitate patient-centered care. The purpose of this study was to explore illness perceptions and the origin of those perceptions in people with chronic disabling non-specific neck pain seeking primary care. METHODS: A qualitative study using a deductive and inductive analytical approach was conducted in 20 people with persistent (> 3 months) and disabling (i.e., Neck Disability Index ≥ 15) neck pain. Using a semi-structured format, participants were interviewed about their illness perceptions according to Leventhal's Common Sense Model. Purposive sampling and member checking were used to secure validity of study results. RESULTS: Participants reported multiple symptoms, thoughts and emotions related to their neck pain, which continuously required attention and action. They felt trapped within a complex multifactorial problem. Although some participants had a broader biopsychosocial perspective to understand their symptoms, a biomedical perspective was dominant in the labelling of their condition and their way of coping (e.g., limiting load, building strength and resilience, regaining mobility, keep moving and being meaningful). Their perceptions were strongly influenced by information from clinicians. Several participants indicated that they felt uncertain, because the information they received was contradictory or did not match their own experiences. CONCLUSION: Most participants reported that understanding their pain was important to them and influenced how they coped with pain. Addressing this 'sense making process' is a prerequisite for providing patient-centered care.

Exercise-Induced Hypoalgesia in Patients with Chronic Whiplash-Associated Disorders: Differences between Subgroups Based on the Central Sensitization Inventory.

BACKGROUND: Physical exercise is an important element in the rehabilitation of chronic whiplash-associated disorders, with the physiological process underlying pain reduction called exercise-induced hypoalgesia. In chronic whiplash-associated disorders, exercise-induced hypoalgesia appears impaired, and the research suggests a relationship with symptoms of dysfunctional nociceptive processing, such as central sensitization. This study improves our understanding of exercise-induced hypoalgesia in chronic whiplash-associated disorders by examining the differences between the extent of exercise-induced hypoalgesia in subgroups based on scores on the central sensitization inventory (CSI). METHODS: Data were collected from 135 participants with chronic whiplash-associated disorders who completed a set of questionnaires. Pain pressure thresholds and temporal summations were assessed before and after a submaximal aerobic bicycle exercise test. RESULTS: We observed no interaction effect between exercise-induced hypoalgesia and the CSI scores for both pain pressure threshold and temporal summation. No overall statistical effect was measured in the analysis of the effect of time. The pain pressure threshold significantly related to the CSI. The temporal summation showed no correlation. CONCLUSIONS: During this study, we did not find evidence for a difference in the presence of exercise-induced hypoalgesia when the subgroups were created based on the central sensitization cluster calculator. Limited evidence was found for the influence of CSI scores on the delta pain pressure threshold.

Physical therapists' perspectives of patient values and their place in clinical practice: a qualitative study.

BACKGROUND: In physical therapy practice patients and therapists exchange their perspectives on musculoskeletal health problems and their meaning for both of them. However, literature indicates that physical therapists find it difficult to enquire about the patients' values during clinical encounters. OBJECTIVES: The aim of this study was to gain deeper insight into the perspectives of physical therapists about patient values. DESIGN: Explorative qualitative focus group study. METHOD: Twenty-three physical therapists were interviewed in the Netherlands from March to May 2021. Two researchers analyzed the interviews and derived relevant codes. After an iterative process of comparing, analyzing, conceptualizing and discussing the codes, themes were identified through a thematic framework, illustrated with meaningful quotes. RESULTS: Three major themes were identified: Humane, Tacit, and Responsive. It appeared that patient values play unconsciously a major role in daily practice and are associated with humanity, not technical or procedural aspects of the encounter. Responsive denotes that all values require interaction in which aligning with the individual patient forms the basis of treatment. Barriers for being responsive are identified as subthemes: Choices, Trust, Diverseness, and Boundaries. CONCLUSION: The concept of patient values appeared to be implicit. The professional intuitively attunes as a fellow human being to values and expectations of the individual patient. This study contributes to finding a balance and mutual reinforcement of implicit and explicit knowledge. With all found experiences and insights the concept of patient values became more explicit in physical therapy to create a framework for education and research in the future.

Exercise into pain in chronic rotator cuff related shoulder pain: a prospective single-group feasibility study.

OBJECTIVES: This study evaluated the feasibility of exercising into pain in rotator cuff related shoulder pain (RCRSP), data collection procedures, feedback from physiotherapists and patients, and clinically important changes in patient-reported outcome measures (PROMs). DESIGN: Unblinded non-randomised single-group study. SETTING: Physiotherapy clinic in Belgium. PARTICIPANTS: Twelve patients with unilateral RCRSP for minimum 3 months, aged 18-65 years. INTERVENTIONS: Twelve weeks of four individualised exercises, with nine physiotherapist-led sessions with pain ratings 4-7 out of 10 on a verbal Numeric Pain Rating Scale for 9 weeks and then pain ratings 0-2 for 3 weeks. Every physiotherapy session included 15 min of manual therapy. Non-supervised exercises were: 2×/week in weeks with physiotherapy session, 3×/week in weeks without physiotherapy session. OUTCOME MEASURES: Primary: adherence, where patients were considered adherent with 78% (7/9 sessions) attendance for supervised sessions and 81% (22/27 sessions) completion for non-supervised exercises, and Shoulder Pain and Disability Index (SPADI); secondary: fear-avoidance behaviour, fear of pain, physical outcomes (strength, range of motion, scapular dyskinesis); others: ultrasound (US) imaging outcomes (acromionhumeral distance, supraspinatus tendon thickness, occupation ratio), global perceived effect (GPE). PROMs were collected via online survey, except for the GPE (via closed envelope). US measures were taken after physical measures. RESULTS: Adherence and adverse effects were analysed in patients who had the possibility to attend minimum seven supervised sessions (n=8): 88% of them adhered to supervised sessions, 50% to non-supervised exercises; none of them withdrew from the study, three of them obtained individual clinically important improvements in SPADI score above 20 points. The measurement protocol of physical and ultrasonographic outcomes took around 60 min. CONCLUSIONS: Adherence to supervised sessions was satisfactory, the adherence to non-supervised exercises must be improved. Data collection procedures were feasible to perform, but some changes are recommended. TRIAL REGISTRATION NUMBER: NCT04154345.

Unravelling Impaired Hypoalgesia at Rest and in Response to Exercise in Patients with Chronic Whiplash-Associated Disorders: Effects of a Single Administration of Selective Serotonin Reuptake Inhibitor versus Selective Norepinephrine Reuptake Inhibitor.

(1) Background: Noradrenaline and serotonin have modulatory roles in pain signaling and in exercise-induced hypoalgesia. Patients with chronic whiplash-associated disorders often show impaired exercise-induced hypoalgesia. Therefore, this study aimed to examine the isolated effect of activating serotonergic or noradrenergic descending pathways on hypoalgesia at rest and in response to exercise in patients with chronic WAD by using respectively a single dose of a selective serotonin reuptake inhibitor (SSRI) and a selective norepinephrine reuptake inhibitor (NRI). (2) Methods: Twenty-five people with chronic WAD participated in this double-blind randomized controlled crossover experiment. Serotonin and noradrenaline concentrations were modulated by the oral ingestion of a single dose of citalopram (i.e., SSRI) or atomoxetine (i.e., SNRI). Quantitative sensory testing (including pressure pain thresholds and conditioned pain modulation) was measured before and after exercise in combination with no medication (1), atomoxetine (2), or citalopram (3) at three different test days. (3) Results: Random-intercept linear mixed models analysis was used to analyze pain outcomes (i.e., pain at rest and exercise-induced hypoalgesia) before and after exercise over the three conditions in patients with chronic WAD. No differences in pain at rest were found between the three conditions before exercise. The effect of exercise on pain outcome measures was not influenced by medication intake. The occupational status of the participants had a significant influence on the effect of exercise and medication on pain outcomes (p < 0.05). Patients working full-time had some positive effect of atomoxetine on pain facilitation (p < 0.05). Unemployed patients had some negative effect of citalopram on pain tolerance and experienced exercise-induced hypoalgesia (p < 0.05). (4) Conclusions: A single dose of citalopram or atomoxetine did not result in changes in hypoalgesia at rest and in response to exercise. These results do not support the use of SSRI or selective NRI to overcome impaired hypoalgesia at rest or in response to exercise in people with chronic WAD. Effect of exercise and medication on pain in patients with chronic WAD is influenced by the occupational status.

Visual feedback manipulation in virtual reality to influence pain-free range of motion. Are people with non-specific neck pain who are fearful of movement more susceptible?

BACKGROUND: Movement-evoked pain may have a protective or learned component, influenced by visual cues which suggest that the person is moving towards a position that may be perceived as threatening. We investigated whether visual feedback manipulation in virtual reality (VR) had a different effect on cervical pain-free range of motion (ROM) in people with fear of movement. METHOD: In this cross-sectional study, seventy-five people with non-specific neck pain (i.e., neck pain without a specific underlying pathology) rotated their head until the onset of pain, while wearing a VR-headset. Visual feedback about the amount of movement was equal, 30% smaller or 30% larger than their actual rotation. ROM was measured using the VR-headset sensors. The effect of VR manipulation in fearful (N = 19 using the Tampa Scale for Kinesiophobia (TSK) and N = 18 using the Fear Avoidance Beliefs Questionnaire-physical activity (FABQpa)) and non-fearful (N = 46; non-fearful on both scales) people was compared using mixed-design ANOVAs. RESULTS: Fear of movement, influenced the effect of visual feedback manipulation on cervical pain-free ROM (TSK: p = 0.036, Õ²p2 = 0.060; FABQpa: p = 0.020, Õ²p2 = 0.077); a greater amplitude of pain-free movement was found when visual feedback reduced the perceived rotation angle compared to the control condition (TSK: p = 0.090, Õ²p2 = 0.104; FABQpa: p = 0.030, Õ²p2 = 0.073). Independent of the presence of fear, visual feedback manipulation reduced the cervical pain-free ROM in the overstated condition (TSK: p< 0.001, Õ²p2 = 0.195; FABQpa: p<0.001, Õ²p2 = 0.329). DISCUSSION: Cervical pain-free ROM can be influenced by visual perception of the amount of rotation and people with fear of movement seem to be more susceptible to this effect. Further research in people with moderate/severe fear is needed to determine whether manipulating visual feedback may have clinical applicability to make patients aware that ROM may be influenced more by fear than tissue pathology.

Reliability of coracohumeral distance and subcoracoid tendons in subacromial pain syndrome.

This study investigated the intra-rater reliability of a novice ultrasound (US) examiner and the inter-rater reliability of two examiners (novice, expert) in the measures of coracohumeral distance at rest (CHD) and at 60° of elevation without (CHD60) or with weights (CHD60w), tendon thickness of the long head of the biceps (LHB) and subscapularis (SCP). Twenty-one patients with subacromial pain syndrome (SAPS) and 20 asymptomatic participants were included. Intra and inter-rater reliability were tested with intraclass-correlation-coefficient (ICC), differences between raters were analyzed with Bland-Altman plots. Intra-rater reliability for CHD, CHD60 and CHD60w was excellent (ICC = 0.97-0.98) in asymptomatic participants, and good-to-excellent (0.88-0.93) in SAPS, while intra-rater reliability for LHB and SCP was good-to-excellent in asymptomatic participants (0.88-0.97) and in SAPS (0.90-0.92). Inter-rater reliability for CHD, CHD60 and CHD60w was moderate-to-good (0.70-0.90) in asymptomatic participants and good (0.85-0.87) in SAPS, in contrast inter-rater reliability for LHB and SCP was poor in asymptomatic participants (0.10-0.46) and poor-to-moderate (0.49-0.61) in SAPS. Bland-Altman plots revealed systematic and/or proportional bias for tendons' thickness. A novice showed good-to-excellent intra-rater reliability in all US measures, whereas in comparison to an expert a novice can measure reliably CHD, CHD60 and CHD60w, but not LHB and SCP, where more training is recommended.

Immediate effects of dry needling on pain sensitivity and pain modulation in patients with chronic idiopathic neck pain: a single-blinded randomized clinical trial.

BACKGROUND: Dry needling is frequently used for the treatment of neck pain but knowledge about its neurophysiological central effects is scarce. OBJECTIVES: To compare the immediate effects of a single session of dry needling (DN) and sham needling (SN) on local and distant pressure pain thresholds and conditioned pain modulation in patients with chronic idiopathic neck pain. METHOD: Participants with chronic idiopathic neck pain were randomly allocated to a DN or SN group. The primary outcome measure was the pressure pain threshold (PPT) at one peripheral location: quadriceps muscle (Q). Secondary outcome measures were local PPTs at the treated (most painful) (tUT) and non-treated upper trapezius muscle (ntUT), absolute and relative conditioned pain modulation (CPM) effects and pain during hot water immersion. Patients were assessed at baseline and immediately post intervention. Linear mixed models were used to examine interaction effects as well as between- and within-group differences. RESULTS: Fifty-four participants were included for statistical analysis. Linear mixed model analyses showed no significant "group X time" interaction effects for any of the outcome measures. The relative CPM effect at the Q was significantly higher post-intervention, compared to baseline within the DN group (mean difference= 13.52%; 95% CI: 0.46, 26.59). CONCLUSION: The present study shows no superior effect of DN, compared to SN, in the immediate effect on local and distant PPTs and CPM in patients with chronic idiopathic neck pain.

Subacromial space measured by ultrasound imaging in asymptomatic subjects and patients with subacromial shoulder pain: an inter-rater reliability study.

BACKGROUND: Acromiohumeral distance (AHD) and supraspinatus tendon thickness (STT) measured by ultrasound (US) can be combined in the occupation ratio (OR). Inter-rater reliability on these subacromial measures depends on the US experience of raters and on the subject status, differing between asymptomatic or patients with subacromial shoulder pain (SSP). OBJECTIVE: To evaluate inter-rater reliability between two raters with different US experience (experienced examiner and novice examiner). METHODS: In total, 20 asymptomatic subjects (controls) and 21 patients with SSP were examined on one shoulder. Inter-rater reliability was evaluated with intraclass correlation coefficient (ICC). RESULTS: ICC for controls was good for AHD at rest and at 60° (0.76-0.77), moderate for STT and AHD at 60° with weights (0.53-0.72), while OR was poorly reliable (below 0.44). ICC for SSP was moderate for AHD at rest and at 60°, STT, OR at rest and at 60° (0.52-0.74) and poor for AHD at 60° with weights and OR at 60° with weights (0.33-0.36). Bland-Altman plots showed systematic bias. CONCLUSION: Inter-rater reliability varied largely from poor to good between two examiners with different US experience. Clinicians might use the US as additional tool for detecting the subacromial structures, but a structured training including also symptomatic subjects is suggested. Researchers may further investigate the OR in matched case-control studies, and an overall agreement phase is recommended before starting the inter-rater reliability phase.

Risk Factors to Persistent Pain Following Musculoskeletal Injuries: A Systematic Literature Review.

BACKGROUND: Musculoskeletal (MSK) injury is one of the major causes of persistent pain. OBJECTIVE: This systematic literature review explored the factors that lead to persistent pain following a MSK injury in the general population, including athletes. METHODS: A primary literature search of five electronic databases was performed to identify cohort, prospective, and longitudinal trials. Studies of adults who diagnosed with a MSK injury, such as sprains, strains or trauma, were included. RESULTS: Eighteen studies involving 5372 participants were included in this review. Participants' ages ranged from 18-95 years. Most of the included studies were of prospective longitudinal design. Participants had a variety of MSK injuries (traumatic and non-traumatic) causing persistent pain. Multiple factors were identified as influencing the development of persistent pain following a MSK injury, including high pain intensity at baseline, post-traumatic stress syndrome, presence of medical comorbidities, and fear of movement. Scarcity of existing literature and the heterogeneity of the studies made meta-analysis not possible. CONCLUSIONS: This systematic review highlighted factors that might help predict persistent pain and disability following MSK injury in the general population, including athletes. Identification of these factors may help clinicians and other health care providers prevent the development of persistent pain following a MSK injury.

Differences in Quantitative Sensory Testing Outcomes Between Patients With Low Back Pain in Primary Care and Pain-free Controls.

OBJECTIVES: Quantitative Sensory Testing (QST) is used to test somatosensory functioning in on people with chronic LBP in secondary/tertiary health care facilities. Studies using QST-testing on LBP populations in primary care are scarce. Central Sensitization Inventory (CSI) measures central sensitization (CS)-related symptoms and studies investigating the differences between QST-testing and participants with LBP with a positive and negative score on the CSI questionnaire are also rare. This case-control study investigates differences of an extensive QST-measurement between patients with acute, chronic LBP, and pain-free controls (PFCs) in primary care. Secondary aim is to investigate differences of an extensive QST-measurement between "CS" and "no-CS" group. MATERIALS AND METHODS: Participants with LBP were recruited from November 2016 to October 2019. Demographic and clinical information was collected and a standardized QST protocol was taken. Data analysis involved determining differences between groups. RESULTS: Data of 100 participants with LBP and 50 PFCs were analyzed. Heat pain thresholds, pressure pain threshold, and conditioned pain modulation local and remote were significantly moderately to relatively strongly affected by acute, chronic LBP and PFCs (P<0.001 to 0.001). Lumbar temporal summation was significantly moderately affected by acute, chronic LBP, and PFCs (P=0.001). Only pressure pain threshold showed significant difference between "CS" and "no-CS" group (P=0.001 to 0.002). DISCUSSION: Signs of enhanced nociceptive processing and disturbed top-down nociceptive modulation are apparent in people with acute and chronic LBP in primary care. Results indicate existence of central mechanisms in LBP in primary care.

Effects of previous experience with dry needling therapy on blinding effectiveness and pain outcomes in people with neck pain: A preliminary sham-controlled study.

BACKGROUND: Participants' previous experience with an intervention may be an important variable when conducting sham-controlled trials. OBJECTIVE: This study explored if previous experience with dry needling (DN) influenced blinding effectiveness and pain outcomes, after the application of DN in patients with neck pain. DESIGN: A preliminary randomized, sham-controlled study. METHODS: Participants were randomized to receive a single session of real or sham DN. Previous experience with DN (yes/no) was recorded. Blinding effectiveness was assessed by asking participants to guess their group allocation (real/sham/not sure) 5 min post-intervention. Outcomes including pain intensity, pressure pain thresholds, and self-perceived improvement, were assessed by a blinded assessor at baseline, one- and seven-days post-intervention. RESULTS: Of 50 patients recruited, 30 had previous experience and 20 did not. Fifty-seven percent (n = 17/30) with previous experience and 35% (n = 7/20) without experience correctly identified their group allocation, but this difference was not significant (χ2 = 2.333; P = 0.127). No interaction between previous experience and clinical outcomes were found, except that participants with previous experience receiving real DN showed greater improvements in pain during cervical rotation than those without previous experience at one (Δ -11.5 mm 95%CI -22.0 to -1.0 mm) and seven days (Δ -8.5 mm, -16.00 to -1.0 mm) post-intervention. CONCLUSIONS: Participants with previous experience were 22% more accurate at identifying their group allocation than those without experience, but the difference was not significant. Previous experience did not influence most clinical outcomes, except for pain intensity after real DN. Future studies evaluating effects of previous experience of DN should include more detailed information of previous experience.

Can Patient Expectations Modulate the Short-Term Effects of Dry Needling on Sensitivity Outcomes in Patients with Mechanical Neck Pain? A Randomized Clinical Trial.

OBJECTIVE: Dry needling is commonly used for the management of patients with musculoskeletal pain. However, the effects of patient expectations are uncertain. Our aim was to determine the effect of patient expectations on short-term clinical outcomes after the application of a single session of dry needling in individuals with neck pain. METHODS: We conducted a randomized, placebo-controlled clinical trial including 50 patients with mechanical neck pain. Participants received a single session of dry needling or sham needling in a blinded design. Predicted patient expectation was categorized as positive, neutral, or negative. Outcomes including neck pain intensity (visual analog scale, 0-100), pressure pain thresholds, and self-perceived improvement (Global Rating of Change, -7 to +7) were assessed at baseline, 1 day after the intervention (immediately after), and 7 days after the intervention (1 week after) by a blinded assessor. Repeated-measures analyses of covariance were conducted to assess the effects of real/sham needling adjusted by patient expectations. RESULTS: Individuals receiving dry needling exhibited better outcomes immediately and 1 week after the intervention than did those receiving sham needling (all P < 0.01). No general effects of patient expectations, either related to pain recovery or functional improvement, were observed on the clinical outcomes, except for a small association of questionable clinical relevance between positive expectations and localized pressure pain thresholds in the dry needling group. CONCLUSION: This study did not find a significant effect of predicted patient expectations on the short-term effects of dry needling on pain intensity and pressure pain thresholds in people with mechanical neck pain.

Specific versus Non-Specific Exercises for Chronic Neck or Shoulder Pain: A Systematic Review.

The current systematic review aimed to compare the effect of injury-focused (specific) exercises versus more general (non-specific) exercises on pain in patients with chronic neck or shoulder pain. We searched PubMed, EMBASE, and Web of Science. Two reviewers screened and selected studies, extracted outcomes, assessed risk of bias, and rated the quality of evidence. A total of nine eligible studies, represented in 13 articles, were identified, with a considerable risk of bias. One article investigated the acute effect of single bouts of exercise on pain and reported an immediate pain reduction after non-specific exercise. Regarding short-term effects, seven out of the nine studies found no differences in pain between interventions, with inconsistent results among two other studies. Concerning the long-term effects, while pain reduction seems to be favored by specific exercises (two out of four articles), the best format is still unclear. Based on the acute effects, a single bout of non-specific exercise seems to be a better option for pain-relief for patients with chronic neck or shoulder pain. For short-term effects, there are no differences in pain between specific and non-specific exercises. Regarding long-term effects, specific exercises seem to be the best option. Nevertheless, more studies are warranted.

Nociplastic Pain Criteria or Recognition of Central Sensitization? Pain Phenotyping in the Past, Present and Future.

Recently, the International Association for the Study of Pain (IASP) released clinical criteria and a grading system for nociplastic pain affecting the musculoskeletal system. These criteria replaced the 2014 clinical criteria for predominant central sensitization (CS) pain and accounted for clinicians' need to identify (early) and correctly classify patients having chronic pain according to the pain phenotype. Still, clinicians and researchers can become confused by the multitude of terms and the variety of clinical criteria available. Therefore, this paper aims at (1) providing an overview of what preceded the IASP criteria for nociplastic pain ('the past'); (2) explaining the new IASP criteria for nociplastic pain in comparison with the 2014 clinical criteria for predominant CS pain ('the present'); and (3) highlighting key areas for future implementation and research work in this area ('the future'). It is explained that the 2021 IASP clinical criteria for nociplastic pain are in line with the 2014 clinical criteria for predominant CS pain but are more robust, comprehensive, better developed and hold more potential. Therefore, the 2021 IASP clinical criteria for nociplastic pain are important steps towards precision pain medicine, yet studies examining the clinimetric and psychometric properties of the criteria are urgently needed.

Physiotherapy in nursing homes. A qualitative study of physiotherapists' views and experiences.

BACKGROUND: There are distinct differences in the implementation of physiotherapeutic care in nursing homes. Both nationally and internationally staffing levels of physiotherapy differ significantly between and within nursing homes. Since legislation or guidelines that specify the parameters of physiotherapy required in nursing homes are lacking, it is unknown how physiotherapists currently estimate the usefulness and necessity of physiotherapy in individual situations in long-term care. The purpose of this study was to describe how physiotherapists actually work, and how they want to work, in daily practice in Dutch nursing homes. METHODS: We performed a qualitative study with an online questionnaire. We asked 72 physiotherapists working in Dutch nursing homes to describe as accurately as possible usual care in nine different cases in long-term care. Furthermore we asked them to describe their role in the prevention and treatment of a number of indicators that measure the quality of care in nursing homes. Two reviewers thematically analysed the answers to the questionnaires. RESULTS: Forty-six physiotherapists returned the questionnaire. Physiotherapy services include active exercise therapy aimed to improve mobility and movement dysfunctions, advising on prevention and management of falls, pressure ulcers, incontinence, malnutrition and sarcopenia, overweight, physical restraints, intertrigo, chronic wounds, behavioural and psychological symptoms in dementia, and physical inactivity, and ergonomic and behavioural training. The way and extent in which physiotherapists are involved in the various care- and functional problems differs and depends on organisational and personal factors such as, organisation's policy, type of ward, time pressure, staffing level, collaboration with other members of the multidisciplinary team, or lack of knowledge. CONCLUSION: Physiotherapists in nursing homes are involved in the prevention and management of different care situations and functional problems. The way in which they are involved differs between physiotherapist. Aiming for more uniformity seems necessary. A shared vision can help physiotherapists to work more consistently and will strengthen their position in nursing homes.
