Functional Disability at 3 Months in Patients with Residual Limb Swelling after Snakebite Envenoming.

Limited data indicate that snakebite survivors have persistent musculoskeletal disability. We assessed the pain and functional disability at hospital discharge and after 3 months in 47 patients treated for snakebite envenoming and with at least a specified amount of local swelling at the time of hospital discharge, using the numerical pain rating scale and the Patient-Specific Functional Scale (PSFS). Russell's viper was the most common biting snake species identified. At hospital discharge, the median pain score was 2 (0-3); 9 (19%) patients reported mild persisting pain at 3 months. The median PSFS score at hospital discharge was 3.7 (3.3-4.0), which improved to 8.3 (6.3-9.0) on follow-up (P <0.001); 32 (68%) patients had a PSFS score of 8.9 or below on follow-up. We conclude that snakebite envenoming could be associated with persisting functional disability at 3 months even in the absence of local complications such as skin necrosis and compartment syndrome.

Reliability, measurement error, and validity of the Arabic version of the Patient-Specific Functional Scale in patients with upper extremity musculoskeletal disorders.

To evaluate the measurement properties of the Arabic Patient-Specific Functional Scale (PSFS) in individuals with upper extremity musculoskeletal disorders. Participants with upper extremity musculoskeletal disorders (N = 139) completed the PSFS, Upper Extremity Functional Index (UEFI), the Disabilities of the Arm, Shoulder and Hand (DASH), Numeric Pain Rating Scale (NPRS) and the Global Assessment of Function scale (GAF). The same outcome measures were completed again with one week in addition to the Global Rating of Change Scale. The test-retest reliability, measurement error, floor and ceiling effects, and construct validity of the PSFS were examined. The PSFS demonstrated very good test-retest reliability (ICC2,1 = 0.82; 95% CI: 0.71-0.88), with no evidence of floor or ceiling effects. The standard error of measurement was determined to be 0.74 while the minimal detectable change was 1.73 points. The PSFS demonstrated significant negative correlation with DASH, NPRS (-0.58, -0.35), and significant positive correlation with the UEFI and GAF (0.56, 0.50). The PSFS demonstrated statistically higher correlation with the DASH and UEFI compared with the NPRS (p < 0.004) supporting our predefined construct validity hypotheses. The Arabic PSFS is an applicable, reliable, and valid outcome measure of upper-extremity activity limitations for patients with upper extremity musculoskeletal disorders.

Effectiveness of gluteal control training in chronic low back pain patients with functional leg length inequality

Chronic low back pain (LBP) is a common musculoskeletal disorder and is often accompanied by functional leg length inequality (FLLI). However, little was known about the effects of gluteal muscle control training in patients with LBP and FLLI. This study was designed to investigate the effects of gluteal control training in patients with LBP and FLLI. This is a double-blinded, randomized controlled study design. Forty-eight LBP patients with FLLI were randomized to the gluteal control training (GT) (47.58 ± 9.42 years) or the regular training (RT) (47.38 ± 11.31 years) group and received allocated training for six weeks. The outcome measures were pelvic inclination (PI), ilium anterior tilt difference (IATD), FLLI, visual analogue scale (VAS), patient specific-functional scale (PSFS), Oswestry disability index (ODI), hip control ability, global rating of change scale (GRoC), and lower extremity strength and flexibility. The intervention effects were compared using two-way repeated measures analysis of variance and chi-square tests with α = 0.05. The results indicated that the GT group showed greater improvement (P < 0.01) in PI (1.03 ± 0.38∘ vs. 1.57 ± 0.51∘), IATD (0.68 ± 0.66∘ vs. 2.31 ± 0.66∘), FLLI (0.3 ± 0.22 vs. 0.59 ± 0.13 cm), VAS (1.41 ± 1.32 vs. 3.38 ± 1.51), hip control ability (2.20 ± 0.45 vs. 0.89 ± 0.74), GRoC at 3rd and 6th week as compared to the RT group. Hip strength and flexibility also improved more in the GT group (P < 0.05). In conclusion, gluteal control training was more effective in improving low back pain and dysfunctions, and should be integrated in the management plan in patients with LBP and FLLI.

Personalised decision support in the management of patients with musculoskeletal pain in primary physiotherapy care: a cluster randomised controlled trial (the SupportPrim project).

We developed the SupportPrim PT clinical decision support system (CDSS) using the artificial intelligence method case-based reasoning to support personalised musculoskeletal pain management. The aim of this study was to evaluate the effectiveness of the CDSS for patients in physiotherapy practice. A cluster randomised controlled trial was conducted in primary care in Norway. We randomised 44 physiotherapists to (1) use the CDSS alongside usual care or (2) usual care alone. The CDSS provided personalised treatment recommendations based on a case base of 105 patients with positive outcomes. During the trial, the case-based reasoning system did not have an active learning capability; therefore, the case base size remained the same throughout the study. We included 724 patients presenting with neck, shoulder, back, hip, knee, or complex pain (CDSS; n = 358, usual care; n = 366). Primary outcomes were assessed with multilevel logistic regression using self-reported Global Perceived Effect (GPE) and Patient-Specific Functional Scale (PSFS). At 12 weeks, 165/298 (55.4%) patients in the intervention group and 176/321 (54.8%) in the control group reported improvement in GPE (odds ratio, 1.18; confidence interval, 0.50-2.78). For PSFS, 173/290 (59.7%) patients in the intervention group and 218/310 (70.3%) in the control group reported clinically important improvement in function (odds ratio, 0.41; confidence interval, 0.20-0.85). No significant between-group differences were found for GPE. For PSFS, there was a significant difference favouring the control group, but this was less than the prespecified difference of 15%. We identified several study limitations and recommend further investigation into artificial intelligence applications for managing musculoskeletal pain.

The Adolescent Patient Perspective on Activity Limitations After Sport-Related Concussion.

Assessment of sport-related concussion (SRC) has begun to include patient-reported outcome measures. However, understanding of which health limitations are most meaningful to adolescents after SRC is limited. To explore patient-perceived activity limitations after SRC and throughout recovery to return to play and mapped according to the International Classification of Functioning, Disability, and Health (ICF) model. Longitudinal study. Secondary school athletic training facilities. Fifty patients (41 males, 5 females, 4 sex not reported, age = 14.9 ± 3.5 years, grade = 10.2 ± 0.93 level) with a medically diagnosed SRC. The Patient Specific-Functional Scale (PSFS) was used to assess changes in the patient's condition and the effect the injury posed on their ability to perform activities. The PSFS is a self-reported assessment of health used to identify activity limitations and rate the difficulty of performing those tasks. The PSFS was administered to patients on days 3 (D3) and 10 (D10) after SRC and at return to play. Activities affected by injury were coded into common categories and themes by a 3-person research team for subsequent analysis. The coded themes were also mapped to the ICF domains, chapters, and categories. The dependent variables were the PSFS themes, number of activities endorsed, PSFS scores, ICF domains, chapters, and categories. Descriptive analyses and frequencies were reported for the dependent variables. A total of 157 different activities were identified at D3 and coded into 28 categories that fit into 6 themes: activities of daily living, cognitive and school (COG), sports and physical activity (SPA), screen time, sleep, and social. On D3, all patients (50/50) identified at least 1 activity limitation. Most related to SPA (37.6%) and COG (31.2%). Sixty percent of patients endorsed activity limitations at D10, primarily in COG (38.6%) and SPA (36.6%). All (100%) response categories were mapped to the ICF, with most (75%) fitting the activities and participation domain. Our primary findings suggest that SRC influences many facets of the lives of adolescent athletes. Specifically, adolescent athletes identified activity restrictions primarily related to physical activity and sports participation.

Applying Clinical Practice Guidelines on Chronic Headaches, Neck Pain, and Chest Symptoms: A Single Case Report

BACKGROUND: Neck pain and headaches are common conditions in physical therapy practice. Clinical practice guidelines (CPGs) are forms of evidence designed to decrease practice variability and guide care. CPG recommendations are general, with few specific tactics recommended, which could be a factor in their limited adoption and poor application. This case report demonstrates an example of implementing the Academy of Orthopedic Physical Therapy Neck Pain Revision CPG while also highlighting limitations and areas lacking specificity. CASE PRESENTATION: The patient was a 37-year-old female with neck pain, chest pain, and headaches. She was treated following the recommendations within the Academy of Orthopedic Physical Therapy CPG along with psychologically informed practice. The Neck Disability Index (NDI), Patient-Specific Functional Scale, Fear-Avoidance Beliefs Questionnaire, symptoms, and impairments were measured at evaluation, discharge, and 2 months post discharge. OUTCOMES: Clinically meaningful improvements in NDI and Patient-Specific Functional Scale scores, improved cervical endurance, scapular strength, and cervical motor control were observed at discharge. Additional improvements in NDI scores were seen at 2 months post discharge. DISCUSSION: While the CPG promotes the use of manual therapy, exercise, and general screening, the authors demonstrate specific techniques for identifying and managing fear-avoidance behavior with cognitive and graded exposure techniques.

The Patient Specific Functional Scale - Brazil as an instrument for the functional assessment of patients with chronic non-specific low back pain: Construct validity (hypothesis testing and structural validity) and test-retest reliability

The objective was to assess the validity and reliability of the Patient-Specific Functional Scale-Brazil (PSFS-B) in patients with non-specific chronic low back pain. A methodological study was conducted, and 101 volunteers with chronic non-specific low back pain were interviewed and asked to complete the PSFS-B questionnaire and the Oswestry Disability Index-Brazil 2.0 reference questionnaire. The Oswestry Disability Index-Brazil 2.0 is a standardized tool used to assess functional disability of the lumbar spine. A new assessment (follow-up) was conducted one week later using the same instruments. The COSMIN checklist was utilized as a guide. Two questionnaires were employed to assess patients: the Patient-Specific Functional Scale-Brazil (PSFS-Br) and the Oswestry Disability Index-Brazil 2.0 (ODI-Br). Data were analyzed to assess construct validity (hypothesis testing and structural validity), internal consistency, and test-retest reliability. The statistical methods employed included Pearson's correlation coefficient, confirmatory factorial analysis, Cronbach's alpha, and intraclass correlation coefficient. The results of the Patient-Specific Functional Scale-Brazil demonstrated a moderate negative correlation with the ODI-Br in hypothesis testing (r = −0.691 and r = −0.754) and in structural validity (Comparative Fit Index (0.986), Tucker-Lewis Index (0.958), Root Mean Square Error of Approximation (0.194), and Standardized Root Mean Square Residual (0.134). Furthermore, the instrument demonstrated excellent internal consistency (α = 0.951) and test-retest reliability (intraclass correlation coefficient = 0.978), and was additionally validated by the Bland-Altman plot (0.125). In conclusion, the Patient-Specific Functional Scale-Brazil is a valid and reliable tool for the evaluation and follow-up of patients with non-specific chronic low back pain.

Lumbar Spine and Neural Tissue Mobilizations Improve Outcomes in Runners Presenting With Foot/Ankle Pathology: A Case Series.

Foot/ankle pain is common among runners. Inadequate management of runners with foot/ankle pain can lead to lost training time, competition removal, and other activity limitations. Neurodynamics, which refers to the integrated biomechanical, physiological, and structural function of the nervous system during movement, can be overlooked in patients with foot/ankle pain. Although a link between the cervical spine, neurodynamics, and upper quarter pain has been studied, less is known about the relationship between the lumbar spine and lower quarter. This case series describes the successful management of 3 runners with foot/ankle pain. Three female runners (ages 23, 24, and 45y) presented to physical therapy with foot/ankle pain and difficulty running. Each patient had positive examination findings with local foot/ankle testing. A comprehensive lumbar spine examination demonstrated impairments in range of motion and joint mobility that were hypothesized to be contributing. Positive lower quarter neurodynamic tests were also found. All patients were treated with nonthrust lumbar spine mobilization and lower quarter neural tissue mobilization. Changes in the Patient-Specific Functional Scale, Numerical Pain Rating Scale, Lower Extremity Functional Scale, and Global Rating of Change occurred after intervention targeting the lumbar spine and lower-extremity neurodynamics in all patients. This case series demonstrates the importance of including a thorough lumbar spine examination and neurodynamic testing to identify appropriate interventions while managing patients with foot/ankle pain, even when patients have signs indicative of local ankle/foot pathology. These examination procedures should be performed particularly when a patient is not responding to management targeting local foot/ankle structures.

Psychometric properties of patient-reported outcome measures assessing recovery from hand fractures: a systematic review.

To extensively review Patient Reported Outcome Measures (PROMs) used to assess outcomes in persons with hand fractures in terms of their psychometric properties. A COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) methodological review was conducted. Six electronic databases were searched (Medline, Embase, Scopus, Web of Science, PsycINFO, CINAHL) for studies evaluating the psychometric properties of PROMs assessing recovery from hand fracture. Titles and abstracts, full text review, quality assessment and data extraction were performed by two reviewers. Any disagreements were resolved after review by a third, expert reviewer. Quality assessment of included studies was performed using the COSMIN checklist. This COSMIN review found that there were only 4 studies that fulfilled the inclusion criteria in terms of assessing measurement properties of PROMs in hand fractures. Only the construct validity of the Disabilities of the Arm, Shoulder, and Hand (DASH), the Quick DASH (QDASH) and the Duruoz Hand Index (DHI), and the responsiveness of the DASH, the Patient Specific Functional Scale (PSFS), the Patient-Rated Wrist and Hand Evaluation (PRWHE) and the Michigan Hand Outcomes Questionnaire (MHQ) were assessed in these studies. The overall rating of the studies was assessed as insufficient or indeterminate and quality of evidence was assessed as moderate, low, or very low by our team. This study identified that there is a lack of evidence in the medical literature with regards to the measurement properties of PROMs in patients with hand fractures. The 4 included studies do not provide good quality data to support the use of these PROMS in patients with hand fractures. There is a need for more studies for more PROMs. This has important consequences for how outcomes will be measured in clinical studies in hand research and in clinical practice.

Facial Swelling and Neuritis After Internal Carotid Endarterectomy in an 81-Year-Old Woman With Type 2 Diabetes Mellitus: A Case Report.

Patients with type 2 diabetes mellitus (DM2) may develop carotid artery stenosis (CAS), requiring surgical intervention. Nerve injury following carotid endarterectomy (CEA) is a rare and often unrecognized post-operative side effect. This case report describes the diagnostic process and rehabilitation course of a patient with greater auricular and trigeminal neuritis symptoms following internal CEA. The patient is an 81-year-old woman with DM2 who underwent a left internal CEA. She subsequently developed swelling in her left neck and face, and pain along the greater auricular and trigeminal nerve pathways. Pertinent examination findings included incision placement across the path of the greater auricular nerve and cervical lymphatic vessels that drain the face, with overlying scar adhesion. A course of physical therapy was initiated 12days after surgery, and included mobilization and manual lymphatic drainage, modalities, and application of kinesiotape. The Patient Specific Functional Scale (PSFS) improved from 10/30 at evaluation to 27/30 at discharge. Swelling and pain were significantly reduced, with patient reporting no difficulty with sleeping, chewing, or talking at discharge. The reported pain level consistently correlated with fluctuations in face swelling throughout treatment. Patients with DM2 may present with symptoms of cardiovascular disease, requiring invasive surgical procedures. DM2 can cause damage to neural and vascular structures, predisposing patients to nerve injuries or hypersensitivity following procedures. This case report demonstrates a likely connection between post-operative facial swelling and nerve irritation in the head and neck. Mobilization and manual lymphatic drainage, modalities, and kinesiotape were effective to reduce pain and swelling. Physical therapists are uniquely qualified to identify, evaluate, and treat post-operative swelling and nerve pain associated with CEA.

Patient-reported physical activity, pain, and fear of movement after cardiac surgery: a descriptive cross-sectional study

Objectives After cardiac surgery, there may be barriers to being physically active. Patients are encouraged to gradually increase physical activity, but limited knowledge exists regarding postoperative physical activity levels. This study aimed to assess patient-reported physical activity six months after cardiac surgery, determine adherence to WHO's physical activity recommendations, and explore potential relationships between pain, dyspnea, fear of movement, and activity levels. Methods The study design was a cross-sectional study at Örebro University Hospital, Sweden. Preoperative and surgical data were retrieved from medical records and questionnaires concerning physical activity (Frändin-Grimby Activity Scale, the Physical activity Likert-scale Haskell, Patient-Specific Functional Scale, and Exercise Self-efficacy Scale) were completed six months after surgery. Data were collected on pain, dyspnea, general health status and kinesiophobia i.e. fear of movement, using the Tampa Scale of Kinesiophobia Heart. Results In total, 71 patients (68 ± 11 years, males 82%) participated in this study. Most patients (76%) reported a light to moderate activity level (Frändin-Grimby levels 3-4) six months after cardiac surgery. In total, 42% of the patients adhered to the WHO’s physical activity recommendations (150 min/week). Pain and dyspnea were low. Patients with lower activity levels exhibited significantly higher levels of fear of movement (p =.025). Conclusions The majority of patients reported engaging in light to moderate activity levels six months after cardiac surgery. Despite this, less than half of the patients met the WHO's physical activity recommendations. Potential barriers to physical activity such as pain, dyspnea and fear of movement were reported to be low.

Factors associated with patient-reported mouth opening activity limitations in individuals with persistent intra-articular temporomandibular disorders: A cross-sectional study exploring physical and self-reported outcomes

BackgroundIndividuals living with intra-articular temporomandibular disorders (IA-TMDs) often report limitations with mouth opening activities. While clinical measures such as active range of motion (AROM) and movement quality are often used to assess mouth opening function, it is unclear if and how these relate to patient-reported limitations and whether other factors such as kinesiophobia influence mouth opening activities in those with IA-TMDs. ObjectivesCompare clinical measures of mouth opening function in those with IA-TMDs to asymptomatic controls. In those with an IA/TMD, explore relationships between patient-reported mouth opening limitations, and mouth opening function and kinesiophobia. DesignCross-sectional study. MethodClinical mouth opening function (AROM, movement quality, pain on movement/10, stiffness on movement/10) was compared between groups (n = 30 IA-TMD, n = 30 controls). Within the IA-TMD group, correlations between patient-reported mouth opening limitations (Patient specific functional scale), kinesiophobia (Tampa Scale for Kinesiophobia for Temporomandibular Disorders) and clinical measures of mouth opening function were explored. ResultsImpairments in AROM (-4 mm, p = 0.04, d = 0.5), movement quality (p < 0.01, φ = 0.6), pain on movement (p < 0.01, d = 0.8) and stiffness on movement (p < 0.01, d = 1.6) were observed in the IA-TMD group compared to controls. Patient-reported mouth opening limitations and kinesiophobia were significantly correlated (r = −0.48, p < 0.01); no correlation was found between patient-reported limitations and clinical mouth opening measures (r < 0.3, p > 0.05). ConclusionsMouth opening function is impaired in IA-TMD. However, kinesiophobia appears more related to patient-reported mouth opening limitations than clinical impairments. Consideration of clinical, kinesiophobia and patient-reported limitation measures are necessary to direct management of IA-TMD in those presenting for care.

Gender-stratified analysis of psychosocial factors and physical function in higher education students with musculoskeletal pain

Purpose To evaluate the prevalence of psychosocial factors in higher education students with musculoskeletal pain and whether these factors are associated with physical function. Materials and methods Participants were higher education students with musculoskeletal pain. The data were collected using questionnaires: the Patient-Specific Functional Scale, the Short Form of the Örebro Musculoskeletal Pain Screening Questionnaire (ÖMPSQ-SF) and the Mental Health Index (MHI-5). The associations were analysed using a generalised linear model, adjusted for the region of Finnish Student Health Service in Finland, age, level of education and field of study. Results A total of 242 women and 104 men (N = 346, mean age 28 ± 8 years) participated in the study. The prevalence of psychosocial factors varied from 16% to 25% among women and 14% to 18% among men, depending on the measurement tool used. Psychosocial factors were associated with lower physical function in women (p = .011) and men (p < .001) when measured with ÖMPSQ-SF, but not with MHI-5. Conclusions Psychosocial factors are prevalent among higher education students experiencing musculoskeletal pain. Furthermore, psychosocial factors exhibit an association with lower physical function when assessed using the ÖMPSQ-SF but not when using the MHI-5. These findings emphasise the importance of addressing psychosocial factors through screening in direct access physiotherapy.

The efficacy of an eight-week exercise program for the management of chronic low back pain in the equestrian population.

Equestrians (horse riders) are more susceptible to low back pain than the general population due to loads placed on their bodies during the activity. A specific eight-week exercise intervention program targeting the muscles used during horse riding was implemented for a group of equestrians with low back pain. Volunteers were invited to participate in the study through social media posts in Melbourne, Australia. The participants were required to complete an exercise screening test prior to enrolment in the study to ensure they were suitable to participate in the iteration program. Participants then completed the Brief Pain Inventory (BPI) (Short Form) and Patient Specific Functional Scale (PSFS) before commencing the exercise program. These outcome measures were completed again by participants after completing the 8-week exercise program. Nine equestrians (23-65 years of age; mean=43±14: average worst back pain on riding=7/10 with a range of 3-10/10) completed all outcome measures and the 8-week exercise intervention. Data indicate that all achieved improved pain severity, pain interference and riding functionality (P<0.01). An eight-week exercise program may be beneficial in improving a sample of equestrians' chronic LBP symptoms. From a practitioner's perspective, the findings provide an indication as to suitable exercises to prescribe to an equestrian to help reduce their LBP.

An EDucation and eXercise intervention for gluteal tendinopathy in an Irish setting: a protocol for a feasibility randomised clinical trial (LEAP-Ireland RCT).

Gluteal tendinopathy (GT) is a degenerative tendon condition characterised by pain over the greater trochanter of the hip. A randomised controlled trial (RCT) in Australia found that 14 sessions of EDucation on load management plus eXercise (EDX) delivered over 8 weeks resulted in greater improvements in global rating of change and pain outcomes at 8 and 52 weeks, compared with corticosteroid injection or 'wait and see'. Typically, 5-6 physiotherapy sessions are provided in public and private physiotherapy settings in Ireland, therefore, the aim of this study is to examine the feasibility of conducting a future definitive RCT to investigate effectiveness of 6 sessions of the EDX programme compared to usual care. We will randomly allocate 64 participants with GT to physiotherapist-administered EDX or usual care. The EDX intervention (EDX-Ireland) will be delivered in 6 sessions over 8 weeks.To determine feasibility of an RCT, we will assess recruitment and retention and outcome measure completion. The health status outcomes to be assessed at baseline, 8 weeks and 3 months include: Global Rating of Change, pain severity, the Victorian Institute of Sport Assessment-Gluteal Questionnaire (VISA-G), the Patient-Specific Functional Scale, the Pain Catastrophizing Scale, Patient Health Questionnaire (PHQ), Pain Self-Efficacy Questionnaire, the EQ-5D-5L, the Central Sensitisation Inventory and hip abductor muscle strength. We will explore acceptability of the EDX-Ireland intervention from the perspective of patients and treatment providers, and the perspective of referrers to the trial. A Study Within A Trial will be also applied to compare recording of exercise adherence using app-based technology to paper diaries. There is a need to establish effective treatments for GT that potentially can be implemented into existing health systems. The findings of this feasibility trial will inform development of a future definitive RCT. The trial is registered prospectively on ClinicalTrials.gov ( NCT05516563, 27/10/2022).

Pain, Function and Trunk/Hip Flexibility Changes Immediately after Clinical Pilates Exercises in Young Adults with Mild Chronic Low Back Pain

Background: Pilates is among the best conservative management strategies for chronic low back pain. However, several variations of Pilates exist. This study aimed to investigate physical measures that would detect immediate changes after a brief session of Clinical Pilates exercises. Changes in self-reported clinical outcomes, pain and function were also evaluated. Methods: A prospective cohort study was conducted. Eighteen young adults with chronic low back pain participated in this study. Participants were assessed for pain and function subjectively, and hip/knee strength and trunk/hip flexibility objectively, followed by a session of Clinical Pilates assessment and exercises. After the exercises, the participants were immediately reassessed for pain, function, strength, and flexibility. Results: Trunk/hip flexibility showed statistically significant changes after exercise, which were measured with the sit-and-reach test (−3.44 cm, 95% CI [−5.10, −1.79], p &lt; 0.001) and the finger-to-floor test (−6.29 cm [−9.51, −3.06], p = 0.001). Statistical significance was not found in detecting strength changes in hip extension, hip abduction, and knee extension. Changes in pain (1.56 points [0.83, 2.28], p &lt; 0.001) and patient-specific functional scale (−1.52 points [−1.93, −1.10], p &lt; 0.001) were also found after exercise. Conclusions: Trunk/hip flexibility measures detected physical changes after Clinical Pilates exercise, as well as self-reported pain and function outcomes, without reducing strength performance.

The Validity and Responsiveness of the Patient-Specific Functional Scale in Patients With First Carpometacarpal Osteoarthritis

The purpose of this study was to assess the content, construct, and discriminative validity and responsiveness of the Patient-Specific Functional Scale (PSFS) in patients with thumb carpometacarpal arthritis. Data were collected at Xpert Clinics, comprising 34 outpatient hand surgery and hand therapy clinics in the Netherlands. We included 267 patients for content validity and 323 patients for construct validity and responsiveness. The PSFS items were classified into the International Classification of Function Core Set for Hand Conditions to assess content validity. We used hypothesis testing to investigate the construct validity and responsiveness. The Michigan Hand Outcomes Questionnaire was used as a comparator instrument. The standardized response mean was calculated to evaluate the magnitude of change. For discriminative validity, we used independent t tests to discriminate between satisfied and dissatisfied patients. We classified 98% of the PSFS items in the International Classification of Function "activities" and "participation" domains, indicating good content validity. Two of six hypotheses for construct validity and three of six hypotheses for responsiveness were confirmed. The standardized response mean for the PSFS was 0.57 (0.46-0.68) and 0.47 (0.35-0.58) for the Michigan Hand Outcomes Questionnaire total score. The mean PSFS score showed good discriminative validity because it could distinguish between satisfied and dissatisfied patients at the 3-month follow-up. The PSFS scores showed good content and discriminative validity in patients with first carpometacarpal arthritis. Hypothesis testing for responsiveness and construct validity indicates that the PSFS measures a unique construct different from the Michigan Hand Outcomes Questionnaire. The PSFS may be a useful scale for measuring the patient-specific status of individuals with thumb carpometacarpal arthritis.

Embedded motivational interviewing combined with a smartphone application to increase physical activity in people with sub-acute low back pain: a cluster randomised controlled trial

BackgroundModerately vigorous physical activity (PA) may be beneficial for people with sub-acute low back pain (LBP), but may initially be painful for patients and challenging for physical therapists to facilitate. ObjectivesThis study investigated motivational interviewing (MI) delivered by physical therapists and a smartphone app for increasing PA in people with LBP. MethodsA mixed methods cluster randomised controlled trial involving 46 adults with LBP in Melbourne, Australia. Participants attended weekly 30-min physical therapy consultations for 6 weeks. Experimental group physical therapists were taught to embed MI into consultations and patients were provided with a self-directed app. The primary outcome was accelerometer-derived moderately vigorous PA. Secondary outcomes were LBP disability (Oswestry Disability Index), functional capacity (Patient Specific Functional Scale), and self-efficacy (Pain Self-Efficacy Questionnaire). Between-group differences were analysed by ANCOVA post-intervention. ResultsThere was no statistically significant difference between the experimental group and control group for PA. Between-group differences in LBP disability (MD= 19.4 units, 95% CI: 8.5, 30.3), functional capacity (primary MD= −4.1 units, 95% CI: −6.9, −1.3; average MD= −3.1, 95% CI: −4.9, −1.2) and self-efficacy (MD −11.3 units, 95%CI −20.2, −2.5) favoured the control group with small to moderate effect sizes. There were low levels of overall engagement with the app. ConclusionThe embedded MI intervention was no more beneficial than physical therapy alone for PA and was associated with poorer LBP disability, function, and self-efficacy. The effectiveness of embedding MI and a smartphone app into usual care for LBP was not supported.

PATH-2 TRIAL: PLATELET-RICH PLASMA FOR ACUTE ACHILLES TENDON RUPTURE. TWO-YEAR FOLLOW-UP OF THE RANDOMIZED, PLACEBO-CONTROLLED, SUPERIORITY TRIAL

BackgroundThe PATH-2 trial found no evidence of a benefit of Platelet Rich Plasma (PRP) injection versus a placebo after Achilles tendon rupture (ATR) at six-months. ATR often leave longer-term functional deficiencies beyond six-months. This study aim is to determine if PRP affect tendon functional outcomes at two-years after rupture.Study designRandomised multi-centre two-arm parallel-group, participant- and assessor-blinded, superiority trial.MethodsAdults with acute ATR managed non-surgically were recruited in 19 UK hospitals from 2015 to 2019. Exclusions were insertion or musculotendinous injuries, leg injury or deformity, diabetes, haematological disorder, corticosteroids and anticoagulation therapy. Participants were randomised via an online system 1:1 to PRP or placebo. Primary outcome was Achilles Tendon Rupture Score (ATRS) at two-years. Secondary outcomes were pain, Patient-Specific Functional Scale (PSFS), SF-12 and re-rupture. Assessors were blinded. Intention-to-treat and Compliance Average Causal effects (CACE) analyses were carried out. Consistency of effects across subgroups age, BMI, smoking and gender were assessed using Forest plots. Pearson's correlation was used to explore ATRS correlation with blood and growth factors.Results216/230 (94%) participants completed the 6-months follow-up were contacted. 182/216 (84%) completed the two-year follow-up. Participants were aged mean 46 (SD 13.0), 57 female/159 male. 96% received the allocated intervention. Two-years ATRS scores were 82.2 (SD 18.3) in the PRP group (n=85) and 83.8 (SD 16.0) in the placebo group (n=92). There was no evidence of a difference in the two-years ATRS (adjusted-mean difference −0.752 95%CI −5.523 to 4.020, p=0.757), or in any secondary outcome, and no re-rupture between at two-years. Neither PRP cellular or growth factors correlated with the two-year ATRS.ConclusionPRP did not improve patient-reported function or quality of life two-years after acute Achilles tendon rupture, compared with placebo, indicating that PRP offers no patient benefit in the longer term.
