Resistance training in women with myotonic dystrophy type 1: a multisystemic therapeutic avenue.

Myotonic dystrophy type 1 (DM1) is a hereditary disease characterized by muscular impairments. Fundamental and clinical positive effects of strength training have been reported in men with DM1, but its impact on women remains unknown. We evaluated the effects of a 12-week supervised strength training on physical and neuropsychiatric health. Women with DM1 performed a twice-weekly supervised resistance training program (3 series of 6-8 repetitions of squat, leg press, plantar flexion, knee extension, and hip abduction). Lower limb muscle strength, physical function, apathy, anxiety and depression, fatigue and excessive somnolence, pain, and patient-reported outcomes were assessed before and after the intervention, as well as three and six months after completion of the training program. Muscle biopsies of the vastus lateralis were also taken before and after the training program to assess muscle fiber growth. Eleven participants completed the program (attendance: 98.5 %). Maximal hip and knee extension strength (p < 0.006), all One-Repetition Maximum strength measures (p < 0.001), apathy (p = 0.0005), depression (p = 0.02), pain interference (p = 0.01) and perception of the lower limb function (p = 0.003) were significantly improved by training. Some of these gains were maintained up to six months after the training program. Strength training is a good therapeutic strategy for women with DM1.

Age- and Parkinson-related differences in trunk and lower-limb muscle activation during four balance tasks: A case-control pilot study.

BACKGROUND: Poor postural control has been reported in people with Parkinson's disease, which could be explained by the changes in muscular activation patterns related to antigravitational muscles. This study aims to measure the muscle activation of antigravitational muscles during balance tasks in individuals, with and without Parkinson's. METHODS: Sixteen (16) participants (9 with Parkinson's), aged ≥65 yrs., performed 2 × 30-s trials of 4 balance tasks (bipodal and semi-tandem opened eyes and closed eyes) on a force platform (center of pressure measurement); while surface electromyography measurements were obtained bilaterally on the multifidus at L5, biceps femoris and medialis gastrocnemius. Electromyography amplitude analysis was processed by the Root Mean Square (250 ms window epochs) and normalized by the peak of activation during the balance task, to determine each muscle's activity level. FINDINGS: The Parkinson's group reported lower muscle activation than control across tasks (in mean for multifidus = 8%, biceps femoris = 16%, gastrocnemius = 7%), although not statistically significant. Parkinson's reported significantly poorer postural control than control, mainly for the center of pressure sway ellipse area (p = 0.016) from challenge balance tasks such as semi-tandem. INTERPRETATION: Poor postural control was confirmed in the Parkinson's group, but not significantly associated by the changes from muscle activation of trunk and lower limbs, during balance performance.

Physical impairments, activity limitations, and participation restrictions of childhood acute lymphoblastic leukemia survivors with and without hip osteonecrosis: a PETALE cohort study.

PURPOSE: Long-term musculoskeletal complications represent a growing burden for survivors of childhood acute lymphoblastic leukemia (cALL). This study aimed to describe physical impairments, activity limitations, and participation restrictions in a high-risk subgroup of cALL survivors of the PETALE cohort. METHODS: This cross-sectional study, using observational data from the PETALE cohort, included a subgroup of survivors who presented high-risk criteria for late effects. Outcomes measures consisted of hip magnetic resonance imaging, maximal isometric muscle strength (MIMS) or torque (MIMT), range of motion (ROM), Near Tandem Balance (NTB), 6-Minute Walk Test (6MWT), Five Time Sit-to-Stand Test (FTSST), and health-related quality of life. Descriptive statistics and regression analyses were performed. RESULTS: Survivors (n = 97, 24.2 ± 6.7 years old) showed limited grip strength, FTSST, and NTB performance compared to reference values (p < 0.001). Thirteen participants (14.6%, 18 hips) had hip osteonecrosis (ON) (53.8% male). Higher severity hip ON was found in female survivors (66.7% vs. 22.2%). Survivors with hip ON had reduced hip external rotation ROM compared to those without (p < 0.05). Relationships were found between MIMS and ROM outcomes (r = 0.32, p < 0.01) and with 6MWT (r = 0.39-0.41, p < 0.001). Our multiple linear regression model explained 27.6% of the variance of the 6MWT. CONCLUSIONS: Survivors in our subgroup had clinically significant physical impairments and activity limitations, and those with hip ON showed worst hip impairment outcomes. IMPLICATIONS FOR CANCER SURVIVORS: These findings emphasize the importance of long-term follow-up including physical therapy assessment to help early identification and management of physical impairments and activity limitations in survivors of cALL.

Group Physical Therapy Programs for Military Members With Musculoskeletal Disorders: A Pragmatic Randomized Controlled Trial.

OBJECTIVE: To compare the effects of personalized, supervised group-based programs (ie, group physical therapy programs) and usual one-on-one physical therapy care (ie, usual physical therapy care) on disability for military personnel suffering from low back pain, rotator cuff-related shoulder pain, patellofemoral pain syndrome, or lateral ankle sprain. Secondary outcomes were pain severity, pain-related fear, health-related quality of life, and patients' satisfaction with their condition and care. DESIGN: Non-inferiority pragmatic randomized clinical trial. METHODS: One hundred twenty military personnel from the Canadian Armed Forces, experiencing 1 of 4 targeted musculoskeletal disorders, were consecutively recruited and randomly assigned to group physical therapy programs or usual physical therapy care. Disability, pain severity, pain-related fear, and health-related quality-of-life outcomes were measured at 6, 12, and 26 weeks after baseline. Satisfaction with treatment was evaluated at the end of the intervention. Intention-to-treat analyses using linear mixed models with random effects were used to compare the effects of interventions. Chi-square tests were used to compare satisfaction. RESULTS: There were no significant Time × Group interactions for any of the primary and secondary outcomes (Time × Group: P>.67). Satisfaction with treatment also did not differ between groups (P>.05). Statistically significant and clinically important improvements were observed in both groups for all outcomes after 12 weeks (Time effect: P<.01), except for health-related quality of life (P = .13). CONCLUSION: Group physical therapy programs were not inferior to usual physical therapy care for managing pain, functional capacity, and patients' satisfaction with care of military personnel presenting with various musculoskeletal disorders. Both interventions led to clinical and statistical improvement in pain and function in the mid and long term. Group physical therapy could be an effective strategy to enhance access to care.

Conditioned pain modulation, kinesiophobia, and pain catastrophizing as prognostic factors for chronicity in a population with acute low back pain: An exploratory prospective study.

BACKGROUND: Psychosocial factors and alteration of the somatosensory functions have been associated with persistent low back pain (LBP). A decreased capacity of the central nervous system to modulate pain has been suggested as a potential contributor to the persistence of pain. OBJECTIVE: To investigate whether conditioned pain modulation (CPM), initial symptoms/disability, kinesiophobia, and pain catastrophizing is associated with the transition from acute to chronic LBP. DESIGN: Prospective cohort study. METHOD: Fifty participants presenting with acute LBP (<6 weeks) took part in three evaluation sessions (baseline, 3 and 6 months). At baseline and 3-month evaluations, all participants completed self-administered questionnaires (Oswestry Disability Index [ODI], Short Form of Brief Pain Inventory [BPI-SF], Tampa Scale of Kinesiophobia [TSK] and Pain Catastrophizing Scale [PCS]) and CPM was assessed. At the 6-month evaluation, questionnaires were readministered, and participants were dichotomized according to their status (Non-chronic LBP [NCLBP] or chronic LBP [CLBP]). Univariate tests were used to compare baseline variables between NCLBP and CLBP. RESULTS: No significant baseline difference was found for TSK (p = 0.48), PCS (p = 0.78), CPM (p = 0.82), ODI (p = 0.78), BPI-SF severity (p = 0.50), and interference subscales (p = 0.54) between those categorized as NCLBP or CLBP at 6 months. CONCLUSIONS: This exploratory study failed to support the hypothesis that inefficient CPM mechanisms and the presence of psychological factors could be factors associated with the transition to chronic pain in individuals with acute LBP.

Natural History of Autosomal Recessive Spastic Ataxia of Charlevoix-Saguenay: a 4-Year Longitudinal Study.

Autosomal recessive spastic ataxia of Charlevoix-Saguenay (ARSACS) is a neurologic disorder with generally well-known clinical manifestations. However, few studies assessed their progression rate using a longitudinal design. This study aimed to document the natural history of ARSACS over a 4-year period in terms of upper and lower limb functions, balance, walking capacity, performance in daily living activities, and disease severity. Forty participants were assessed on three occasions over 4 years. Participant performance was reported in raw data as well as in percentage from reference values to consider the normal aging process. Severe balance and walking capacity impairments were found, with a significant performance decrease over the 4 years. Balance reached a floor score of around 6 points on the Berg Balance Scale for participants aged >40 years, while other participants lost about 1.5 points per year. The mean loss in walking speed was 0.044 m/s per year and the mean decrease in the distance walked in 6 min was 20.8 m per year for the whole cohort. Pinch strength, balance, walking speed, and walking distance decreased over time even when reported in percentage from reference values. Major impairments and rapid progression rates were documented in the present study for upper limb coordination, pinch strength, balance, and walking capacity in the ARSACS population. A progression rate beyond the normal aging process was observed. These results provide fundamental insights regarding the disease prognosis that will help to better inform patients, develop specific rehabilitation programs, and improve trial readiness.

Toward a Better Understanding of Walking Speed in Ataxia of Charlevoix-Saguenay: a Factor Exploratory Study.

Mobility limitations, including a decrease in walking speed, are major issues for people with autosomal recessive spastic ataxia of Charlevoix-Saguenay (ARSACS). Improving our understanding of factors influencing walking speed in ARSACS may inform the development of future interventions for gait rehabilitation and contribute to better clinical practices. The objective of the study was to identify the factors influencing the self-selected walking speed in adults with ARSACS. The dependent variable of this cross-sectional study was the self-selected speed and the factors (independent variables) were age, sex, balance, balance confidence, knee flexion and extension cocontraction indexes, lower limb coordination, passive range of motion of ankle dorsiflexion, knee and hip extension, and global spasticity. Multiple regression models were used to assess the relationships between walking speed and each factor individually. Six factors were significantly associated with walking speed and thus included in regression models. The models explained between 42.4 and 66.5% of the total variance of the self-selected walking speed. The factors that most influence self-selected walking speed are balance and lower limb coordination. In order of importance, the other factors that also significantly influence self-selected walking speed are ankle dorsiflexion range of motion, lower limb spasticity, knee extension range of motion, and confidence in balance. Balance and lower limb coordination should be targeted in rehabilitation interventions to maintain walking ability and functional independence as long as possible. The six factors identified should also be included in future studies to deepen our understanding of walking speed.

A proposal for a universal physical therapy diagnostic concept.

BACKGROUND: In Canada, as in other countries, the physical therapist (PT) must make a diagnosis to comply with direct access responsibilities. This means making a diagnosis is an entry-to-practice essential competency. However, there is no consensus across physical therapy practice domains and contexts regarding the diagnostic concept, i.e., the classification system, labelling and diagnostic format that should be used. OBJECTIVE: To propose a universal diagnostic concept, one a PT could use regardless of their practice domain or context. METHODS: The relevant scientific and grey literature (1986-2022) were searched and key information was synthesized. RESULTS: Information from 194 retained documents (8506 identified) was synthesized to a list of seven essential criteria that were then used to develop a universal physical therapy diagnostic concept (PT-Dx-C). The PT-Dx-C format consists of three labels in the following order: (1) health problem, (2) primary impairment, and (3) primary activity limitation or participation restriction. Label definitions are those used by the World Health Organization. The specific health problem, impairment, and limitation or restriction making up the diagnosis are determined for each patient using valid tests and measures. CONCLUSIONS: The PT-Dx-C is consistent with best practices and could be applied to all patients, in all PT practice domains and contexts. It reflects the PT's expertise in the human movement system and their unique contribution to health care. Furthermore, its use may allow for communication of the PT's conclusions in a manner that can be understood by others thereby facilitating collaborative practice.

Integration of primary contact physiotherapists in the emergency department for individuals presenting with minor musculoskeletal disorders: Protocol for an economic evaluation.

OBJECTIVES: 1) To compare the average cost of an emergency department (ED) visit for various minor musculoskeletal disorders between two models of care (physiotherapist and ED physician or ED physician alone); 2) To evaluate the incremental cost-effectiveness ratio (ICER) of these two models of care over a 3-month period post-initial visit; and 3) To estimate the ICER of three ED models of care (physiotherapist and ED physician, ED physician alone, physiotherapist alone) over a two-year period. METHODS: Obj.1: The costs incurred by participants in the two groups during their ED visit will be calculated using the Time-Driven Activity-Based Costing (TDABC) method. These costs will be compared using generalized linear models. Obj. 2: The ICER of the two models will be evaluated over three months via a cost-utility analysis that will combine costs and effectiveness data (quality-adjusted life years) using both Health system and Societal perspectives (patient + health system costs). Obj. 3: The 2-year ICER of the three above-mentioned models will be estimated using a mathematical model including a decision tree (0-3 months post-visit) and a Markov model (3-24 months post-visit), also using both Health system and Societal perspectives. Data to answer the three objectives will come from data collected during a randomized clinical trial (n = 78, CHU de Québec)which will be supplemented with data obtained via some of the CHU de Québec administrative databases (nominative data; SIURGE (ED management software), Cristal-Net (patient electronic record), and the ED's pharmacy transactions directory; administrative data: drug costs repository), the literature, and public cost repositories. CONCLUSION: This study will help to determine which model of care is most efficient for the management of individuals who come to the ED with minor musculoskeletal disorders. The increased involvement of various health professionals in the management of patients in the ED paves the way for the development of new avenues of practice and more efficient organization of services.

Measuring upper limb active joint position sense: Introducing a new clinical tool - The Upper Limb Proprioception Reaching Test.

BACKGROUND: Proprioception is our sense of body awareness, including the sub-category of active joint position sense (AJPS). AJPS is fundamental to joint stability and movement coordination. Despite its importance, there remain few confident ways to measure upper limb AJPS in a clinic. OBJECTIVE: To assess a new AJPS clinical tool, the Upper Limb Proprioception Reaching Test (PRO-Reach; seven targets), for discriminant validity, intra-rater and absolute reliability. DESIGN: Cross-sectional measurement study. METHODS: Seventy-five healthy participants took part in a single session with 2 consecutive evaluations (E1 and E2) (within-day reliability). Twenty participants were randomly selected to perform a dominant shoulder fatigue protocol (discriminant validity), whereafter a third evaluation was repeated (E3). The PRO-Reach was analyzed with paired t tests (discriminant validity), intra-class correlation coefficients (ICCs) and minimal detectable change [MDC]) (intra-rater: within-day and between-trial relative and absolute reliability). RESULTS: The PRO-Reach supports moderate (mostly superior targets) to excellent (mostly inferior targets) reliability. Between-trial ICCs (T1/T2/T3) varied between 0.72 and 0.90, and within-day (E1/E2) ICCs between 0.45 and 0.72, with associated MDC95 values (3.9-5.0 cm). The overall scores (seven targets) supported the strongest within-day reliability (ICC = 0.77). The inferior targets demonstrated the highest between-trial and within-day reliability (ICCs = 0.90 and 0.72). A fatigue effect was found with the superior and superior-lateral targets (P < .05). CONCLUSIONS: The inferior targets and overall scores demonstrate the strongest reliability. The use of the PRO-Reach tool may be suitable for clinical use upon further psychometric testing amongst pathological populations. LEVEL OF EVIDENCE: Level III cross-sectional study.

Psychometric properties of a standardized protocol of muscle strength assessment by hand-held dynamometry in healthy adults: a reliability study.

BACKGROUND: Maximal isometric muscle strength (MIMS) assessment is a key component of physiotherapists' work. Hand-held dynamometry (HHD) is a simple and quick method to obtain quantified MIMS values that have been shown to be valid, reliable, and more responsive than manual muscle testing. However, the lack of MIMS reference values for several muscle groups in healthy adults with well-known psychometric properties limits the use and the interpretation of these measures obtained with HHD in clinic. OBJECTIVE: To determine the intra- and inter-rater reliability, standard error of measurement (SEM) and minimal detectable change (MDC) of MIMS torque values obtained with HHD. METHODS: Intra and Inter-rater Reliability Study. The MIMS torque of 17 muscle groups was assessed by two independent raters at three different times in 30 healthy adults using a standardized HHD protocol using the MEDup™ (Atlas Medic, Québec, Canada). Participants were excluded if they presented any of the following criteria: 1) participation in sport at a competitive level; 2) degenerative or neuromusculoskeletal disease that could affect torque measurements; 3) traumatic experience or disease in the previous years that could affect their muscle function; and 4) use of medication that could impact muscle strength (e.g., muscle relaxants, analgesics, opioids) at the time of the evaluation. Intra- and inter-rater reliability were determined using two-way mixed (intra) and random effects (inter) absolute agreement intraclass correlation coefficients (ICC: 95% confidence interval) models. SEM and MDC were calculated from these data. RESULTS: Intra- and inter-rater reliability were excellent with ICC (95% confidence interval) varying from 0.90 to 0.99 (0.85-0.99) and 0.89 to 0.99 (0.55-0.995), respectively. Absolute SEM and MDC for intra-rater reliability ranged from 0.14 to 3.20 Nm and 0.38 to 8.87 Nm, respectively, and from 0.17 to 5.80 Nm and 0.47 to 16.06 Nm for inter-rater reliability, respectively. CONCLUSIONS: The excellent reliability obtained in this study suggest that the use of such a standardized HHD protocol is a method of choice for MIMS torque measurements in both clinical and research settings. And the identification of the now known metrological qualities of such a protocol should encourage and promote the optimal use of manual dynamometry.

Wheelchair mobility, motor performance and participation of adult wheelchair users with ARSACS: a cross-sectional study.

PURPOSE: Although approximately 45% of adults with Autosomal Recessive Spastic Ataxia of Charlevoix-Saguenay (ARSACS) are permanent wheelchair users, this sub population has been less studied. The purpose of this study was to document wheelchair mobility, motor performance, and participation in a cohort of adult wheelchair users with ARSACS. METHODS: We recruited 36 manual and powered wheelchair users with ARSACS, aged between 34 and 64 years, for this cross-sectional study. Participants completed measures regarding wheelchair mobility (Wheelchair Skills Test Questionnaire [WST-Q-F], Wheelchair Use Confidence Scale [WheelCon-F] and Wheelchair Outcome Measure [WhOM-F]), motor performance (Scale for the Assessment and Rating of Ataxia [SARA], Disease Severity Index for adults with ARSACS [DSI-ARSACS], Upper Extremity Performance Test for the Elderly [TEMPA], Standardised Finger to Nose Test [SFNT], grip strength, pinch strength, Lower Extremity Motor Coordination Test [LEMOCOT], Berg Balance Scale [BBS], Timed Up and Go [TUG] and 10-meter Walk Test [10mWT]), and participation (Barthel Index, LSA-F and LIFE-H). Results were compared between age groups (≤49 years and ≥50 years), types of wheelchair used, and available reference values. Correlations were computed between wheelchair mobility, upper limb function, and participation. RESULTS: Participants presented limitations regarding wheelchair skills, motor performance, and participation in daily activities. Despite preserved upper limb strength, wheelchair skills, upper and lower limb coordination, standing balance, and functional independence were generally more impaired after 50 years of age and among powered wheelchair users. Significant moderate correlations were found between wheelchair skills and self-efficacy, upper limb strength and coordination, and participation in daily and social activities. CONCLUSIONS: This study provided the first data sets describing specific characteristics of manual and powered wheelchair users with ARSACS. It supports a need to offer wheelchair skills training interventions to adults with ARSACS, which could increase their daily and social participation.IMPLICATIONS FOR REHABILITATIONAdult wheelchair users with ARSACS present with limited wheelchair skills, significantly impaired motor performance, and reduced participation that generally decreases with age. This profile may serve as comparative data for clinicians to anticipate disease progression.This study provides the first data on distinguishing characteristics between PWC users and MWC users with ARSACS. The main characteristics of PWC users include more severe functional limitations and motor impairments, as well as limited grip strength that contrasts with the general preservation of this function among other adults with ARSACS.There is a need to offer and evaluate wheelchair skills training interventions in the future for adults with ARSACS. The general preservation of grip and pinch strength observed in this population suggests a potential for improvement. Considering the associations found between wheelchair mobility and participation, such interventions may increase users' daily and social participation.

Impact of a 12-week Strength Training Program on Fatigue, Daytime Sleepiness, and Apathy in Men with Myotonic Dystrophy Type 1.

BACKGROUND: Myotonic dystrophy type 1 (DM1) is a multisystemic neuromuscular disorder causing a plea of impairments, of which fatigue and apathy are some of the most frequent non-muscular symptoms. No curative treatment exists to date, and patients only have access to limited effective care, which are intended to decrease the burden of specific symptoms in daily life. OBJECTIVE: This study aimed to assess whether a 12-week strength training program has an impact on fatigue/daytime sleepiness, apathy, and disease bruden in men with DM1. METHODS: Eleven participants completed the Fatigue and Daytime Sleepiness Scale (FDSS) and the Myotonic Dystrophy Health Index (MDHI) at baseline, at 6 and 12 weeks, and at 6 and 9 months. Also, the Apathy Evaluation Scale (AES) was filled out at baseline, at 12 weeks, and at 6 and 9 months. RESULTS: Results show significant effects of the training program both on apathy and fatigue/daytime sleepiness, effects that are respectively greater at three and six months after the end of the program than at its very end. However, no difference was observed regarding the overall disease burden. CONCLUSION: These findings are promising for patients with DM1 considering that few non-pharmacological treatments are available.

What is Known About Muscle Strength Reference Values for Adults Measured by Hand-Held Dynamometry: A Scoping Review.

Objective: To map the body of existing literature regarding reference values of maximal isometric muscle strength (MIMS) of upper and lower limbs obtained with handheld dynamometers (HHD) in healthy adults to identify potential gaps in the literature and specify future research needs. Data Sources: A scoping review in which PubMed, EMBASE, CINAHL plus, PEDRO, and Cochrane databases were searched before May 1, 2020. Study Selection: All studies using standardized HHD protocols for the purpose of establishing reference values in healthy adult population were included. Two independent reviewers completed an initial screening of article titles and abstracts, and the remaining articles were read in their entirety and screened according to the inclusion and exclusion criteria. Disagreements were discussed, with recourse to a third reviewer when needed. Data Extraction: Data of the selected studies were extracted and charted by 2 independent reviewers using a tested data extraction grid to ensure method standardization. Data were subsequently merged to produce the complete final extracted data. Data Synthesis: Titles and abstracts of 4015 studies were screened, 46 articles were fully reviewed, and 9 manuscripts were selected for the final analysis. A large variability exists between protocols used for muscle testing in terms of type of device, measurement units, subject positioning, and muscle groups tested. Conclusion: The existing literature regarding HHD reference values of MIMS is scarce and presents gaps notably relating to strength units and well-described protocols with known psychometric properties, despite the development and increased availability of high quality HHD. This observation emphasizes the critical need to develop reference values in manual dynamometry in adults to optimize the use of manual dynamometry for diagnostic and prognostic decisions.

Health-Related Quality of Life of Patients Presenting to the Emergency Department with a Musculoskeletal Disorder.

BACKGROUND: Musculoskeletal disorders (MSKDs) are among the most disabling and costly non-fatal health conditions. They may lead to long-term consequences such as chronic pain, physical limitations, and poorer quality of life. They also account for a significant proportion of emergency department visits, representing between 18% and 25% of all visits, depending on country. PURPOSE: To assess the health-related quality of life of patients presenting to the emergency department with a MSKD, to convert their answers to utility scores and to explore the association between diverse socio-demographic and clinical variables and patients' health-related quality of life. PATIENTS AND METHODS: This is an analysis of cross-sectional data obtained during the baseline assessment performed as part of a 6-month pragmatic randomized controlled trial conducted in an academic emergency department. We included patients aged 18-80 years with a minor MSKD. The main outcome measures were health-related quality of life (five dimensions: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression) and utility scores (-0.148 - worse than death, 0 - dead, 0.949 - perfect health) measured with the EQ-5D-5L. Possible associations were explored by comparing scores across subgroups based on certain socio-demographic (eg, age, gender, triage score) and clinical factors (eg, pain interference on function, pain intensity) and with reference values using descriptive statistics (mean, median), rankFD ANOVAs, and χ 2 tests. RESULTS: Sixty-nine participants completed the EQ-5D-5L. Mean and median utility scores were, respectively, 0.536 (95% CI: 0.479-0.594) and 0.531 (IQR: 0.356-0.760). Participants with higher levels of pain (<4/10: 0.741, 95% CI: 0.501-0.980; 4-7/10: 0.572, 0.500-0.644; >7/10: 0.433, 0.347-0.518) or pain interference on function (<4/10: 0.685, 95% CI: 0.605-0.764; 4-7/10: 0.463, 0.394-0.533; >7/10: 0.294, 0.126-0.463) presented significantly lower utility scores. No significant differences were found for other socio-demographic characteristics. CONCLUSION: In patients with MSKDs who present to the emergency department, higher levels of pain or pain interference are associated with decreased health-related quality of life. These findings need to be confirmed on a larger scale.

Strategies to reduce waiting times in outpatient rehabilitation services for adults with physical disabilities: A systematic literature review.

OBJECTIVE: Identifying effective strategies to reduce waiting times is a crucial issue in many areas of health services. Long waiting times for rehabilitation services have been associated with numerous adverse effects in people with disabilities. The main objective of this study was to conduct a systematic literature review to assess the effectiveness of service redesign strategies to reduce waiting times in outpatient rehabilitation services for adults with physical disabilities. METHODS: We conducted a systematic review, searching three databases (MEDLINE, CINAHL and EMBASE) from their inception until May 2021. We identified studies with comparative data evaluating the effect of rehabilitation services redesign strategies on reducing waiting times. The Mixed Methods Appraisal Tool was used to assess the methodological quality of the studies. A narrative synthesis was conducted. RESULTS: Nineteen articles including various settings and populations met the selection criteria. They covered physiotherapy (n = 11), occupational therapy (n = 2), prosthetics (n = 1), exercise physiology (n = 1) and multidisciplinary (n = 4) services. The methodological quality varied (n = 10 high quality, n = 6 medium, n = 3 low); common flaws being missing information on the pre-redesign setting and characteristics of the populations. Seven articles assessed access processes or referral management strategies (e.g. self-referral), four focused on extending/modifying the roles of service providers (e.g. to triage) and eight changed the model of care delivery (e.g. mode of intervention). The different redesign strategies had positive effects on waiting times in outpatient rehabilitation services. CONCLUSIONS: This review highlights the positive effects of many service redesign strategies. These findings suggest that there are several effective strategies to choose from to reduce waiting times and help better respond to the needs of persons experiencing physical disabilities.

Measurement properties of wheelchair use assessment tools in adults with autosomal recessive spastic ataxia of Charlevoix-Saguenay.

PURPOSE: To establish the reliability and construct validity of two French-Canadian versions of assessment tools for manual (MWC) and powered wheelchair (PWC) users with autosomal recessive spastic ataxia of Charlevoix-Saguenay (ARSACS): the Wheelchair Skills Test Questionnaire (WST-Q-F) version 5.0 and the Wheelchair Use Confidence Scale (WheelCon-F) Short Form. METHODS: We recruited 32 MWC and PWC users with ARSACS aged between 34 and 64 years. Participants completed measures twice within 2 weeks for test-retest reliability and to determine the standard error of measurement. Construct validity was established by verifying hypothesized relationships between wheelchair use scores and other variables regarding personal factors, body functions, and activities. Participants' scores were also compared with those of MWC and PWC users with other diagnoses to explore known-groups validity. RESULTS: Adequate to excellent test-retest reliability values were found for all questionnaires (intraclass correlation coefficients between 0.506 and 0.995). SEMs were acceptable, ranging from 3.3 to 9.1 on the WST-Q-F and from 0.7 to 1.2 on the WheelCon-F. Moderate to excellent correlations supported construct validity for the WST-Q-F and the WheelCon-F. Compared with other populations, adults with ARSACS reported limited wheelchair skills, but similar wheelchair confidence. CONCLUSIONS: The WST-Q-F and the WheelCon-F have excellent test-retest reliability, acceptable measurement errors, and support for construct validity in adults with ARSACS. This study was the first to evaluate these assessment tools in this population, and the results support a need to implement wheelchair skills training interventions in this population.IMPLICATIONS FOR REHABILITATIONThe WST-Q-F version 5.0 and the WheelCon-F Short Form are reliable and valid assessment tools to measure manual and powered wheelchair skills and self-efficacy in adults with autosomal recessive spastic ataxia of Charlevoix-Saguenay (ARSACS).The WST-Q-F version 5.0 and the WheelCon-F Short Form can be used to evaluate and describe wheelchair skills and wheelchair use self-efficacy in clinical practice and are recommended for future research in adults with ARSACS. These outcome tools may be especially useful to measure the effects of a wheelchair training program.

Whole-brain morphometry in Canadian soldiers with posttraumatic stress disorder.

Patients with posttraumatic stress disorder (PTSD) display several structural brain differences when compared with healthy individuals. However, findings are particularly inconsistent for soldiers with PTSD. Here, we characterized the brain morphometry of 37 soldiers from the Canadian Armed Forces with adulthood war-related PTSD using structural magnetic resonance imaging. We assessed time since trauma, as well as PTSD, depressive, and anxiety symptoms with the Modified PTSD Symptoms Scale, Beck Depression Inventory, and Beck Anxiety Inventory, respectively. Whole-brain morphometry was extracted with FreeSurfer and compared with a validated normative database of more than 2700 healthy individuals. Volume and thickness from several regions differed from the norms. Frontal regions were smaller and thinner, particularly the superior and rostral middle frontal gyri. Furthermore, smaller left rostral middle frontal gyrus, left pericalcarine cortex, and right fusiform gyrus were associated with more recent trauma. All subcortical structures were bigger, except the hippocampus. These findings suggest a particular brain morphometric signature of PTSD in soldiers. Smaller and thinner frontal and larger subcortical regions support impaired top-down and/or downregulation of emotional response in PTSD. Finally, the correlation of smaller frontal, temporal, and occipital regions with more recent trauma might inform future therapeutic approaches.

Functional mobility in walking adult population with ataxia of Charlevoix-Saguenay.

BACKGROUND: This study aimed to describe lower limbs impairments, balance and activity limitations related to indoor mobility in adult walkers with autosomal recessive spastic ataxia of Charlevoix-Saguenay (ARSACS). RESULTS: Twenty-five participants were recruited with a mean age of 32.2 (± 10.4) years with 45.7% using a walking aid. There is a significant difference between participants with and without a walking aid in terms of lower limbs coordination, balance and mobility. Although participants who walk without a walking aid perform better than the others and they are below predictive or reference values. Despite significant mobility limitations, only mild spasticity and passive range of motion limitations were observed. However, there is a significant difference between unaffected individuals and participants with ARSACS for lower limb muscle cocontraction. CONCLUSIONS: Results show a high level of lower limb impairments, balance and mobility limitation in adults' participants with ARSACS that are still walking, including people not using a walking aid. One of the most original finding is the presence of excessive cocontraction and a relatively mild level of spasticity in the lower limbs muscles. Results of this study better circumscribes the impairments and activities that should be the focus of intervention including rehabilitation in ARSACS.

An in-home rehabilitation program for the treatment of urinary incontinence symptoms in endometrial cancer survivors: a single-case experimental design study.

INTRODUCTION AND HYPOTHESIS: There is a high prevalence of urinary incontinence among endometrial cancer survivors. They are also known to present with pelvic floor muscle alterations. Evidence on the effects of conservative interventions for the management of UI is scarce. This study aims at verifying the effects of an in-home rehabilitation program, including the use of a mobile technology, to reduce UI severity in endometrial cancer survivors. METHODS: This study used a single-case experimental design with replications. Primary outcome for UI severity was the pad test, and secondary outcomes were the ICIQ-UI SF questionnaire and 3-day bladder diary. Pelvic floor muscle function was assessed using 2D-transperineal ultrasound and intravaginal dynamometry. Adherence was documented using mobile technology and an exercise log. Visual and non-parametric analyses of longitudinal data were conducted. RESULTS: Results show a reduction in UI severity for 87.5% of participants, with a significant relative treatment effect of moderate size (RTE: 0.30). Significant small relative treatment effects were found for the quick contraction and endurance dynamometric tests. CONCLUSION: This study provides new evidence that endometrial cancer survivors can improve the severity of their UI following an in-home rehabilitation program, including the use of a mobile technology. This mode of delivery has the potential to address a gap in access to pelvic floor physiotherapy services for survivors of EC living in rural and remote communities.
