ABSTRACT
BACKGROUND: People with chronic musculoskeletal pain (CMSP) often have low physical activity. Various factors can influence the activity level. The aim of this study was to monitor physical activity, assessed by the number of steps per day, over time in people with CMSP and identify factors that could be associated with this activity feature. METHODS: This prospective study involved people undergoing rehabilitation following an orthopedic trauma that had led to CMSP. At entry, participants completed self-reported questionnaires assessing pain, anxiety, depression, catastrophyzing, kinesiophobia, and behavioural activity patterns (avoidance, pacing and overdoing). They also underwent functional tests, assessing walking endurance and physical fitness. To determine daily step counts, participants wore an accelerometer for 1 week during rehabilitation and 3 months post-rehabilitation. The number of steps per day was compared among three time points: weekend of rehabilitation (an estimate of pre-rehabilitation activity; T1), weekdays of rehabilitation (T2), and post-rehabilitation (T3). Linear regression models were used to analyze the association between daily steps at T2 and at T3 and self-reported and performance-based parameters. RESULTS: Data from 145 participants were analyzed. The mean number of steps was significantly higher during T2 than T1 and T3 (7323 [3047] vs. 4782 [2689], p < 0.001, Cohen's d = 0.769, and 4757 [2680], p < 0.001, Cohen's d = 0.693), whereas T1 and T3 results were similar (p = 0.92, Cohen's d = 0.008). Correlations of number of steps per day among time points were low (r ≤ 0.4). Multivariable regression models revealed an association between daily steps at T2 and pain interfering with walking, anxiety and overdoing behaviour. Daily steps at T3 were associated with overdoing behaviour and physical fitness. CONCLUSIONS: Despite chronic pain, people in rehabilitation after an orthopedic trauma increased their physical activity if they were given incentives to do so. When these incentives disappeared, most people returned to their previous activity levels. A multimodal follow-up approach could include both therapeutic and environmental incentives to help maintain physical activity in this population.

Pain has multiple consequences, forcing people to change the way they carry out their activities (domestic, work, leisure, social). Classically, three behavioural strategies have been described: avoidance, modulation, and persistence. Recent research suggests that the use of these strategies is more complex and subtle than previously imagined. Identifying behavioural activity strategies early in the management process with simple, precise, and concrete questions is particularly useful for adapting treatment plans. From a therapeutic point of view, the recommendations for promoting activity are both to choose activities that are valued by the patient in order to reinforce his or her commitment, and to encourage flexibility in the choice of behavioural strategies depending on the context.
La douleur a de multiples conséquences et oblige les personnes en souffrant à changer la manière de réaliser leurs activités (domestiques, travail, loisirs, sociales). Classiquement, trois stratégies comportementales ont été décrites : l'évitement, la modulation et la persistance. La recherche actuelle met en avant plus de complexité et de subtilités dans l'utilisation de ces stratégies. Repérer les stratégies d'activité tôt dans la prise en charge avec des questions simples, précises et concrètes est particulièrement utile pour adapter le traitement. Du point de vue thérapeutique, les recommandations pour favoriser l'activité sont à la fois de choisir celles étant valorisées par le patient pour renforcer son engagement et de favoriser la flexibilité dans le choix des stratégies comportementales selon les contextes.

Physical and rehabilitation medicine (PRM) is an independent medical specialty, little known in Switzerland. This specialty, strongly linked to the holistic approach of the International Classification of Functioning, will be increasingly solicited by the epidemiology of disability and the imperatives of "ageing better". Its skills in prescribing human and material resources for rehabilitation provide added value in terms of loss of autonomy. Based on a biopsychosocial model, PRM has a high role to play in prevention and primary healthcare, as well as in the management and prevention of the consequences of functionally limiting diseases. There are, however, financial (pricing) and demographic (lack of representation) obstacles to effective action on behalf of the population and the healthcare system.
La médecine physique et de réadaptation (MPR), discipline indépendante, est peu connue en Suisse. Cette spécialité, liée à l'approche holistique de la classification internationale du fonctionnement, sera de plus en plus sollicitée par l'épidémiologie du handicap et les impératifs du « vieillir mieux ¼. Ses compétences de prescription des moyens humains et matériels en réadaptation apportent une plus-value sur la perte d'autonomie. Basée sur un modèle biopsychosocial, la MPR trouve sa place dans la prévention et les soins de santé primaires ainsi que dans la prise en charge et la prévention des conséquences des maladies induisant une limitation fonctionnelle. Il existe toutefois des obstacles financiers (tarification) et démographiques (insuffisance de représentation) pour une action efficace au service de la population et du système de santé.

STUDY QUESTION: Do ovarian hormone changes influence the levels of cell-free or circulating microRNA (cf-miRNA) across the menstrual cycle? SUMMARY ANSWER: This exploratory study suggests that fluctuations in hormonal levels throughout the menstrual cycle may alter cf-miRNAs levels. WHAT IS KNOWN ALREADY: cf-miRNA levels vary with numerous pathological and physiological conditions in both males and females and are regulated by exogenous and endogenous factors, including hormones. STUDY DESIGN, SIZE, DURATION: A prospective, monocentric study was conducted between March and November 2021. Since this was a pilot study, the sample size was based on feasibility as well as previous similar human studies conducted in different tissues. A total of 20 participants were recruited for the study. PARTICIPANTS/MATERIALS, SETTING, METHODS: We conducted an exploratory study where blood samples were collected from 16 eumenorrheic females in the early follicular phase, the ovulation phase and the mid-luteal phase of the menstrual cycle. The levels of oestrogen, progesterone, LH and FSH were measured in serum by electrochemiluminescence. The levels of 174 plasma-enriched miRNAs were profiled using a PCR-based panel, including stringent internal and external controls to account for the potential differences in RNA extraction and reverse-transcription stemming from low-RNA input samples. MAIN RESULTS AND THE ROLE OF CHANCE: This exploratory study suggests that cf-miRNAs may play an active role in the regulation of the female cycle by mediating the expression of genes during fluctuating hormonal changes. Linear mixed-models, adjusted for the relevant variables, showed associations between phases of the menstrual cycle, ovarian hormones and plasma cf-miRNA levels. Validated gene targets of the cf-miRNAs varying with the menstrual cycle were enriched within female reproductive tissues and are primarily involved in cell proliferation and apoptosis. LARGE SCALE DATA: All relevant data are available from the Mendeley database: LEGER, Bertrand (2022), 'MiRNA and menstrual cycle', Mendeley Data, V1, doi: 10.17632/2br3zp79m3.1. LIMITATIONS, REASONS FOR CAUTION: Our study was conducted on a small participant cohort. However, it was tightly controlled for endogenous and exogenous confounders, which is critical to ensure robust and reproducible cf-miRNA research. Both adjusted and non-adjusted P-values are presented throughout the article. WIDER IMPLICATIONS OF THE FINDINGS: Measures of ovarian hormones should be rigorously included in future studies assessing cf-miRNA levels in females and used as time-varying confounders. Our results reinforce the importance of accounting for female-specific biological processes in physiology research by implementing practical or statistical mitigation strategies during data collection and analysis.

BACKGROUND: The Constant-Murley Score (CMS) is a relatively unique shoulder assessment tool because it combines patient-reported outcomes (pain and activity), performance measurement and clinician-reported outcomes (strength and mobility). With these characteristics, the effect of patient-related psychological factors on the CMS remains debated. We aimed to investigate which parameters of the CMS are influenced by psychological factors by assessing the CMS before and after rehabilitation for chronic shoulder pain. METHODS: This retrospective study screened all patients (18-65 years old) who were admitted for interdisciplinary rehabilitation for chronic shoulder pain (≥ 3 months) between May 2012 and December 2017. Patients with unilateral shoulder injuries were eligible. Exclusion criteria were shoulder instability, concomitant neurological injuries, complex regional pain syndrome (including Steinbrocker syndrome), heavy psychiatric issues, and missing data. The Hospital Anxiety and Depression Scale, Pain Catastrophizing scale, and Tampa Scale of Kinesiophobia were administered before and after treatment. Regression models were used to estimate associations between psychological factors and the CMS. RESULTS: We included 433 patients (88% male, mean age 47±11 years) with a median duration of symptoms of 392.2 days (interquartile range: 266.5-583.5). Rotator cuff issue was present in 71% of patients. During interdisciplinary rehabilitation, patients were followed for a mean of 33.6±7.5 days. The mean CMS at entry was 42.8 ±15.5. The mean gain in CMS after treatment was 10.6 ±10.9. Before treatment, psychological factors were significantly associated with only the pain CMS parameter: -0.37 (95% CI: -0.46 to -0.28), p <0.001. After treatment, psychological factors were associated with the evolution of the four CMS parameters: -0.12 (-0.23 to -0.01) to -0.26 (95% CI: -0.36 to -0.16), p<0.05. CONCLUSIONS: This study raises the question of a distinct assessment of pain when assessing shoulder function with CMS in patients with chronic shoulder pain. The separation of the "pain parameter" from the overall CMS score seems illusory with this tool that is used worldwide. However, clinicians should be aware that psychological factors can negatively influence the evolution of all CMS parameters during follow-up, which argues for a biopsychosocial approach to patients with chronic shoulder pain.

BACKGROUND AND AIMS: While a causal relationship between pain-related fear and spinal movement avoidance in patients with chronic low back pain (CLBP) has frequently been postulated, evidence supporting this relationship is limited. This study aimed to test if decreases in pain-related fear or catastrophizing were associated with improvements in spinal biomechanics, accounting for possible changes in movement-evoked pain. METHODS: Sixty-two patients with CLBP were assessed before and after an interdisciplinary rehabilitation program (IRP). Pain-related fear was assessed with general and task-specific measures. Lower and upper lumbar angular amplitude and velocity as well as paraspinal muscle activity were recorded during five daily-life tasks to evaluate spinal biomechanics. Relationships were tested with multivariable linear regression analyses. RESULTS: The large decreases in pain-related fear and catastrophizing following the IRP were scarcely and inconsistently associated with changes in spinal biomechanics (< 3% of the models reported a statistically significant association). Results remained comparable for activities inducing more or less fear, for specific or general measures of pain-related fear, and for analyses performed on the entire population or limited to subgroups of patients with higher levels of task-specific fear. In contrast, reductions in task-specific pain-related fear were significantly associated with decreases in movement-evoked pain in all tasks (r = 0.26-0.62, p ≤ 0.02). CONCLUSION: This study does not support an association between pain-related fear and spinal movement avoidance. However, it provides evidence supporting a direct relationship between decreased pain-related fear and decreased movement-evoked pain, possibly explaining some mechanisms of the rehabilitation programs.

OBJECTIVE: To use the self-assessment INTERMED questionnaire to determine the relationship between biopsychosocial complexity and healthcare and social costs of patients after orthopaedic trauma. DESIGN: Secondary prospective analysis based on the validation study cohort of the self-assessment INTERMED questionnaire. SETTING: Inpatients orthopaedic rehabilitation with vocational aspects. SUBJECTS: In total, 136 patients with chronic pain and impairments were included in this study: mean (SD) age, 42.6 (10.7) years; 116 men, with moderate pain intensity (51/100); suffering from upper (n = 55), lower-limb (n = 51) or spine (n = 30) pain after orthopaedic trauma; with minor or moderate injury severity (severe injury for 25). MAIN MEASURES: Biopsychosocial complexity, assessed with the self-assessment INTERMED questionnaire, and other confounding variables collected prospectively during rehabilitation. Outcome measures (healthcare costs, loss of wage costs and time for fitness-to-work) were collected through insurance files after case settlements. Linear multiple regression models adjusted for age, gender, pain, trauma severity, education and employment contract were performed to measure the influence of biopsychosocial complexity on the three outcome variables. RESULTS: High-cost patients were older (+3.6 years) and more anxious (9.0 vs 7.3 points at HADS-A), came later to rehabilitation (+105 days), and showed higher biopsychosocial complexity (+3.2 points). After adjustment, biopsychosocial complexity was significantly associated with healthcare (ß = 0.02; P = 0.003; expß = 1.02) and social costs (ß = 0.03; P = 0.006, expß = 1.03) and duration before fitness-to-work (ß = 0.04; P < 0.001, expß = 1.04). CONCLUSION: Biopsychosocial complexity assessed with the self-assessment INTERMED questionnaire is associated with higher healthcare and social costs.

PURPOSE: To determine the levels of perceived work demand capacity corresponding to the Modified Spinal Function Sort (M-SFS) score and precise reliability validity and responsiveness. METHODS: This prospective validation study included patients with chronic musculoskeletal impairments who underwent multidisciplinary occupational rehabilitation. After determining the percentiles of the work demand thresholds corresponding to the spinal function sort (SFS), the percentiles were transposed to the M-SFS. Reliability was assessed using the intraclass correlation coefficient and limits of agreement. Correlations with other questionnaires and a lifting task were measured to assess validity. Responsiveness was determined using anchor- and distribution-based approaches. RESULTS: 288 patients were included. The following thresholds were obtained for the M-SFS: 0-43 points, minimal; 44-50, very light; 51-58, light; 59-64, light to medium; 65-70, medium; 71-76, heavy; and 77-80, very heavy. Reliability was confirmed. The correlation between the M-SFS and SFS scores was good at 0.89 (95% CI, 0.86-0.91) and moderate according to the PILE-test result of 0.60 (95% CI, 0.50-0.67). We could not calculate a valid anchor-based minimal clinically important difference. The standard error of measurement was 3.9 points, and the smallest detectable change was 10.8 points. CONCLUSIONS: On the basis of the comparison of the M-SFS and SFS scores, the M-SFS score can be interpreted in relation to the levels of work demand. This study confirms the good reliability and validity of the M-SFS questionnaire in assessing perceived physical capacity. Further studies are needed to determine its responsiveness.

The shortening of hospital stays implies rethinking the pre- and post-operative management of lower limb arthroplasty. Optimal preparation of the patient and anticipation of the postoperative process are necessary to limit the length of stay and ensure quality, safety and patient satisfaction. This article summarises what is known about preoperative information, education and rehabilitation for primary care physicians. Physical rehabilitation is not recommended in isolation. However, patient-centred information and education is recommended for those at risk of complicated postoperative outcomes. Interdisciplinary collaboration is needed to coordinate the whole process effectively in a context of shortened lengths of stay.
Le raccourcissement des séjours hospitaliers implique de repenser la prise en charge pré et postopératoire après arthroplastie du membre inférieur. Une préparation optimale du patient et une anticipation du processus postopératoire sont nécessaires pour limiter le séjour et assurer la qualité, la sécurité et la satisfaction des patients. Cet article synthétise, à l'intention des médecins de premier recours, les connaissances concernant l'information, l'éducation et la réadaptation préopératoires. Une réadaptation physique n'est pas recommandée isolément. En revanche, l'information et l'éducation centrées sur le patient sont recommandées chez les sujets à risque de suites opératoires compliquées. Une collaboration interdisciplinaire est nécessaire pour coordonner efficacement l'ensemble du processus avec des durées de séjours réduites.

BACKGROUND: Hand rehabilitation needs valid evaluation tools; the 400-point Hand Assessment (HA) is an exhaustive but not standardised tool. The aim of this study was to validate a standardised version of this test. METHODS: A modified version and a standardised prototype was made for this prospective validation study (four centres, three countries). Psychometric properties studied: reliability (intra-rater and inter-rater, standard error of measurement [SEM], minimum detectable change [MDC],internal consistency); content validity, construct validity with Jebsen Taylor hand function test, QuickDASH, MOS-SF 36 and pain; responsiveness, using an anchor-based approach (ROC curve with area under curve, mean response change) with calculation of MCID. For SEM, MDC and responsiveness, QuickDASH was used for comparison. RESULTS: One hundred and seventy-six patients with hand/wrist injuries were included between May 2013 and February 2015. One hundred and seventy were available for final analysis: 67% men; mean age 43.4 ± 13.2 years; both manual and office workers (46, 5% of each); 37% had a hand or wrist fracture. Reliability: ICC intra-rater = 0.967 [0.938-0.982]; inter-rater = 0.868 [0.754-0.932]. Distribution-based approach: for 400-point HA/QuickDASH: SEM = 3.48/4.52, MDC = 9.065/12.53, internal consistency of 400-point HA: Cronbach α = 0.886. VALIDITY: Content validity was good according to COSMIN guidelines. Construct validity: correlation coefficient: Jebsen-Taylor hand function test = - 0.573 [- 0.666-0.464], QuickDASH = - 0.432 at T0 [- 0.545-0.303], - 0.551 at T3 [- 0.648-0.436]; MOS-SF 36 physical component = 0.395 [0.263-0.513]; no correlation with MOS-SF 36 mental component = 0.142 [- 0.009 + 0.286] and pain = - 0.166 [- 0.306 + 0.018]. Responsiveness: Anchor-based approach: AUC Δ400-point HA = 0.666 [0.583-0.749], AUC ΔQuickDASH = 0.556 [0.466-0.646]. MCID (optimal ROC curve cut-off): 6.07 for 400-point HA, - 2.27 for QuickDASH. MCID with mean response change + 12.034 ± 9.067 for 400-point HA and - 8.03 ± -9.7 for QuickDASH. The patient's global impression of change was only correlated with the Δ400-point HA. CONCLUSIONS: The 400-point HA standardised version has good psychometric properties. For responsiveness, we propose an MCID of at least 12.3/100. However, these results must be confirmed in other populations and pathologies. TRIAL REGISTRATION: This study was retrospectively registered into ISCTRN registry (Number ISRCTN25874481) the 07/02/2019.

OBJECTIVE: First, to determine the number of accident-related complex regional pain syndrome (CRPS) cases from 2008 to 2015 and to identify factors associated with an increased risk for developing CRPS. Second, to analyze the duration of work incapacity and direct health care costs over follow-up periods of two and five years, respectively. DESIGN: Retrospective data analysis. SETTING: Database from the Statistical Service for the Swiss National Accident Insurances covering all accidents insured under the compulsory Swiss Accident Insurance Law. SUBJECTS: Subjects were registered after an accident between 2008 and 2015. METHODS: Cases were retrospectively retrieved from the Statistical Service for the Swiss National Accident Insurances. Cases were identified using the appropriate International Classification of Diseases, 10th Revision, codes. RESULTS: CRPS accounted for 0.15% of all accident cases. Age, female gender (odds ratio [OR] = 1.53, 95% confidence interval [CI] = 1.47-1.60), and fracture of the forearm (OR = 38, 95% CI = 35-42) were related to an increased risk of developing CRPS. Over five years, one CRPS case accumulated average insurance costs of $86,900 USD and treatment costs of $23,300 USD. Insurance costs were 19 times and treatment costs 13 times the average costs of accidents without CPRS. Within the first two years after the accident, the number of days lost at work was 20 times higher in patients with CRPS (330 ± 7 days) than in patients without CRPS (16.1 ± 0.1 days). Two-thirds of all CRPS cases developed long-term work incapacity of more than 90 days. CONCLUSION: CRPS is a relatively rare condition but is associated with high direct health care costs and work incapacity.

BACKGROUND: Functional tests are widely used to measure performance in patients with chronic musculoskeletal pain. Our objective was to determine the Minimal Clinically Important Differences (MCID) for the 6-min walk test (6MWT), the Steep Ramp Test (SRT), the 1-min stair climbing test (1MSCT), the sit-to-stand test (STS), the Jamar dynamometer test (JAM) and the lumbar Progressive Isoinertial Lifting Evaluation (PILE) in chronic musculoskeletal pain patients. METHODS: A single-center prospective observational study was conducted in a rehabilitation center. Patients with upper-limb, lower-limb or neck/back lesions were included over a period of 21 months. We used the anchor-based method as a reference method, supplemented by the distribution-based and opinion-based approaches, to determine the MCIDs. RESULTS: 838 chronic musculoskeletal pain patients were included. The estimation method and thelesion location had a significant influence on the results. MCIDs were estimated at +75m and +60m for the 6MWT (lower-limb and neck/back lesions, respectively), +18 steps for the 1MSCT (lower-limb and neck/back lesions) and +6kg for the JAM (upper limb lesions). The anchor-based method could not provide valid estimations for the three other scales, but distribution and opinion-based methods provided rough values of MCIDs for the SRT (+39w to +61w), the STS (-5 sec to -7 sec) and the PILE (+4kg to +7kg). CONCLUSION: The above MCID estimations for the 6MWT, 1MSCT and JAM can be used in chronic musculoskeletal pain patients participating in vocational multidisciplinary rehabilitation programs or in therapeutic trials. The use of specific anchors might give better estimations of MCIDs for the three other scales in future research.

BACKGROUND: Physical therapy and exercising are key components of biopsychosocial rehabilitation for chronic pain. Exercise helps reduce pain and improve physical functions. In addition, a high level of physical activity benefits quality of life and emotional well-being. However, the degree to which hospitalization for extensive rehabilitation effectively increases physical activity has not yet been studied. Therefore, we investigated the physical activity level and the walking behavior of inpatients with musculoskeletal pain. The objectives were 1) to compare physical activity level and walking with or without rehabilitation, 2) to evaluate whether pain site influences physical activity level, and 3) to measure the association between physical activity and pain-related interference with physical functioning. METHODS: During a rehabilitation stay, 272 inpatients with lower limb, spine, or upper limb pain wore an accelerometer over 1 week. We assessed the daily duration of the practice of moderate physical activity and walking. Weekend days, during which the participants went home (days off), were used as a reference for habitual activities. We also evaluated 93 patients before the hospitalization to validate the use of days off as a baseline. Pain interference was measured with the brief pain inventory questionnaire. Generalized linear mixed models analyzed the association between physical activity and walking levels, and 1) rehabilitation participation, 2) pain sites, and 3) pain interference. RESULTS: Weekend days during the stay have similar physical activity level as days measured before the stay (73 min / day at the clinic, versus 70 min / day at home). Rehabilitation days had significantly higher physical activity levels and walking durations than days off (+ 28 min [+ 37%] and + 32 min [+ 74%], respectively). Mixed models revealed 1) a negative association between physical activity and pain interference, and 2) no effect of pain sites. Overall, patients increased their physical activity level independently of reported pain interference. CONCLUSIONS: Despite their painful condition, the inpatients were able to engage themselves in a higher level of physical activity via increased participation in walking activities. We conclude that walking incentives can be a valid solution to help patients with chronic pain be more physically active.

This article aims to present the principles of rehabilitation following anatomical and reverse total shoulder arthroplasties. The rehabilitation consist of three phases: wound healing and movement initiation (weeks 0-6), movement recovery (7-12), strengthening and return to activity (13-18). At 6 to 12 months follow-up, most patients report a substantial decrease in pain and a return to light to moderate activity level. The rehabilitation of the reverse arthroplasty specifically requires deltoid muscle strengthening and dislocation prevention. The functional outcome is slightly inferior for reverse arthroplasty, which is indicated when musculotendinous lesions are associated to bone lesions, but satisfaction rates are comparable between the two types of implants. The durability of total shoulder arthroplasties is globally satisfying, though shorter in young active patients.
Cet article présente la rééducation après prothèses totales d'épaule anatomique (PTEa) et inversée (PTEi), qui se découpe en 3 phasesâ : cicatrisation et initiation du mouvement (semaines 0-6), récupération du mouvement (7-12), renforcement et retour à l'activité (13-18). Après 6-12 mois, la plupart des patients rapportent une nette diminution des douleurs et une reprise des activités légères à modérées. La rééducation de la PTEi implique spécifiquement de renforcer le muscle deltoïde et de prévenir la luxation. Le résultat fonctionnel est légèrement inférieur pour la PTEi, qui est posée lorsque des lésions musculo-tendineuses sont associées à des lésions osseuses, mais la satisfaction est comparable entre les deux types d'implants. La longévité de ces prothèses, bien que plus courte chez le patient actif jeune, est généralement bonne.

The Complex Regional Pain Syndrome (previously algodystrophy) is a rare affliction that usually affects a distal extremity (hand, foot). It occurs most frequently within weeks following a traumatic injury or stroke. It is a syndromic entity whose diagnosis is based on precise criteria, known as the Budapest criteria, excluding any disease that better explains the symptoms. The treatment must be given early. Functional restoration (physiotherapy, occupational therapy) is at the heart of the treatment, along with psychoeducation. Inappropriate disuse and avoidance, often encountered, must be combated. Bisphosphonates or steroids are first-line drugs at early stages. The evolution is often long, but the prognosis is favorable in about 75â % of cases (≤ 1 year).
Le syndrome douloureux régional complexe (anciennement algodystrophie) est une affection rare qui touche préférentiellement une extrémité (main, pied). Il se développe le plus souvent dans les semaines qui suivent un traumatisme ou un accident vasculaire cérébral. Il s'agit d'une entité syndromique dont le diagnostic repose sur des critères précis, dits de Budapest, excluant toute atteinte expliquant mieux les symptômes. Le traitement doit être précoce. La restauration fonctionnelle en est le cÅur (physiothérapie, ergothérapie), associée à une psychoéducation. L'immobilisation inappropriée et l'évitement, souvent rencontrés, doivent être combattus. Bisphosphonates ou corticoïdes sont les médicaments de premier choix des formes précoces. L'évolution est souvent longue, mais le pronostic favorable dans environ 75â % des cas (≤ 1 an).

Neuroprosthetics research in amputee patients aims at developing new prostheses that move and feel like real limbs. Targeted muscle and sensory reinnervation (TMSR) is such an approach and consists of rerouting motor and sensory nerves from the residual limb towards intact muscles and skin regions. Movement of the myoelectric prosthesis is enabled via decoded electromyography activity from reinnervated muscles and touch sensation on the missing limb is enabled by stimulation of the reinnervated skin areas. Here we ask whether and how motor control and redirected somatosensory stimulation provided via TMSR affected the maps of the upper limb in primary motor (M1) and primary somatosensory (S1) cortex, as well as their functional connections. To this aim, we tested three TMSR patients and investigated the extent, strength, and topographical organization of the missing limb and several control body regions in M1 and S1 at ultra high-field (7 T) functional magnetic resonance imaging. Additionally, we analysed the functional connectivity between M1 and S1 and of both these regions with fronto-parietal regions, known to be important for multisensory upper limb processing. These data were compared with those of control amputee patients (n = 6) and healthy controls (n = 12). We found that M1 maps of the amputated limb in TMSR patients were similar in terms of extent, strength, and topography to healthy controls and different from non-TMSR patients. S1 maps of TMSR patients were also more similar to normal conditions in terms of topographical organization and extent, as compared to non-targeted muscle and sensory reinnervation patients, but weaker in activation strength compared to healthy controls. Functional connectivity in TMSR patients between upper limb maps in M1 and S1 was comparable with healthy controls, while being reduced in non-TMSR patients. However, connectivity was reduced between S1 and fronto-parietal regions, in both the TMSR and non-TMSR patients with respect to healthy controls. This was associated with the absence of a well-established multisensory effect (visual enhancement of touch) in TMSR patients. Collectively, these results show how M1 and S1 process signals related to movement and touch are enabled by targeted muscle and sensory reinnervation. Moreover, they suggest that TMSR may counteract maladaptive cortical plasticity typically found after limb loss, in M1, partially in S1, and in their mutual connectivity. The lack of multisensory interaction in the present data suggests that further engineering advances are necessary (e.g. the integration of somatosensory feedback into current prostheses) to enable prostheses that move and feel as real limbs.

Purpose Measuring the predictive value of the Fear-Avoidance Model (FAM) on lifting tasks in Functional Capacity Evaluation (FCE), and on reasons for stopping the evaluation (safe maximal effort, versus self-limited). Methods A monocentric prospective study was conducted on 298 consecutive inpatients. Components of the FAM were analyzed using the Cumulative Psychosocial Factor Index (CPFI: kinesiophobia, catastrophizing, depressive mood) and perceived disability (Hand/Spinal Function Sort: HFS/SFS). Floor-to-waist, waist-to-overhead and dominant-hand lifting tests were measured according to the FCE guidelines. Maximal safe performance was judged by certified FCE assessors. Analyses were conducted with linear multiple regression models. Results The CPFI was significantly associated with the 3 FCE lifting tests: floor-to-waist (ß = - 1.12; p = 0.039), waist-to-overhead (ß = - 0.88; p = 0.011), and dominant-handed lifting (ß = - 1.21; p = 0.027). Higher perceived disability was also related to lower performances: floor-to-waist (ß = 0.09; p < 0.001), waist-to-overhead (ß = 0.04; p < 0.001), and dominant-handed lifting (ß = 0.06; p < 0.001). The CPFI was not related to performances of patients with self-limited effort despite higher psychological scores, while a relationship was found for patients who achieved a safe maximal performance. Higher perceived disability was related to performances in both situations. Conclusions FAM components should be taken into account when interpreting maximal physical performance in FCE. This study also suggests that factors other than pain-related fears may influence patients with self-limited effort.

Purpose Updating the Wallis Occupational Rehabilitation Risk (WORRK) model formula, predicting non-return to work (nRTW) at different time points (3 and 12 months) than in the validation study (2 years). Methods Secondary analysis of two samples was carried out (following orthopaedic trauma), including work status, the first at 3 months (428 patients) and the second at 12 months (431 patients) after discharge from rehabilitation. We used calibration (agreement between predicted probabilities and observed frequencies) and discrimination (area under the receiver operating characteristics curve) to assess performance of the model after fitting it in the new sample, then calculated the probabilities of nRTW based on the coefficients from the 2-year prediction. Finally, the intercepts were updated for both 3- and 12-month prediction models (re-calibration was necessary for the adjustment of these probabilities) and performance re-evaluated. Results Patient characteristics were similar in all samples (mean age 43 in both groups; 86% male at 3 months, 84% male at 12 months). The proportion of nRTW at 3 months was 63.8% and 53.4% at 12 months (50.36% at 2 years). Performance of the original WORRK for both 3- and 12-month prediction showed an AUC of 0.73, while statistically significant miscalibration was found for both time points (p < 0.001). After the updating of the intercept, calibration was improved and did not show significant miscalibration (p = 0.458 and 0.341). The AUC stayed at 0.73. Conclusion The WORRK model was successfully adapted by changing the intercept for 3- and 12-month prediction of nRTW, now available for use in clinical practice.

A century and a half after its first description, adhesive capsulitis (frozen shoulder) has revealed only part of its secrets. Its definition remains clinical since the imaging technology we have at our dis-posal is insufficiently sensitive and specific. Next to its idiopathic form, the most frequent and the most characteristic, there are numerous situations inducing a functional limitation of the glenohumeral joint and of its environment. The clinical course inexorably takes place in one to two years, and develops in 3 phases where successively pain, retraction, and then recovery, as a rule complete recovery, dominate. No treatment is likely to shorten it. In the absence of clearly established proof, our therapeutic approach must be prudent and conservative.
Un siècle et demi après sa première description, la capsulite rétractile de l'épaule n'a dévoilé qu'une partie de ses secrets. Sa définition reste clinique puisqu'on ne dispose d'aucune méthode d'imagerie suffisamment sensible et spécifique. A côté de la forme idiopathique, la plus fréquente et la mieux caractérisée, il existe une multitude de situations induisant une limitation fonctionnelle de l'articulation gléno-humérale et de son environnement. L'évolution se déroule inexorablement sur un à deux ans et comporte trois phases où dominent successivement la douleur, la rétraction puis la récupération en principe complète. Aucun traitement n'est susceptible de l'écourter. En l'absence de preuve clairement établie, l'approche thérapeutique doit être prudente et conservatrice.
