Post-stroke pathway analysis and link with one year sequelae in a French cohort of stroke patients: the PAPASePA protocol study.

BACKGROUND: Stroke is a health problem with serious consequences, both in terms of mortality, and after-effects affecting patient quality of life. Stroke requires both urgent and chronic management involving the entire health care system. Although large variability in the management of stroke patients have been noticed, knowledge of the diversity and the scalability of post-stroke pathways, whether it is the care pathway or the life pathway, is currently not sufficient. Moreover the link between post-stroke pathways and patients sequelae have not been yet clearly defined. All this information would be useful to better target the needs to improve stroke patient management. The purposes are to identify the post-stroke life pathways components associated with sequelae (activity limitations - main purpose, cognitive disorders, anxio-depressive disorders, fatigue, participation restrictions) at 3 months and 1 year post-stroke, to define a typology of life pathways of patients during the post-stroke year and to analyze the social and geographical inequalities in the management of stroke. METHODS: Design: a prospective multicenter comparative cohort study with a follow up to 1 year after the acute episode. Participant centers: 13 hospitals in the Aquitaine region (France). STUDY POPULATION: patients diagnosed with a confirmed ischemic or hemorrhagic stroke included in the Aquitaine Observatory of Stroke (ObA2) cohort and voluntary to participate. Data sources are existing databases (ObA2 database and the French National Health Data System - SNDS) to collect information about care pathways, patient characteristics and stroke characteristics and Ad hoc surveys to collect information about life pathways and post-stroke sequelae. The endpoints of the study are post-stroke activity limitations evaluated by the modified Rankin score, other post-stroke sequelae (Cognitive disorders, anxio-depressive disorders, fatigue, restriction of participation) assessed by standardized and validated scales and Clusters of patients responding to pathways with common or similar characteristics.; DISCUSSION: By integrating a longitudinal dimension and relying on a large cohort, the project will make it possible to identify the sources of disturbances and the factors favorable to the outcome of the life pathways, important for the planning of the offer and the management of the public policies concerning stroke pathways.

Five-year follow-up of persons with brain injury entering the French vocational and social rehabilitation programme UEROS: Return-to-work, life satisfaction, psychosocial and community integration.

BACKGROUND: Social and vocational reintegration of persons with brain injury is an important element in their rehabilitation. AIMS: To evaluate the 5-year outcome of persons with brain injury included in 2008 in the Aquitaine Unit for Evaluation, Training and Social and Vocational Counselling programme (UEROS). METHOD: 57 persons with brain injury were recruited from those who completed the 2008 UEROS programme. Five years later, an interview was done to assess family and vocational status, autonomy and life satisfaction. These results were compared with those from persons completing the 1997-1999 programme. RESULTS: The typical person entered the 2008 UEROS programme 6 years after a severe brain injury (42%) and was male, single and 35 years. At the 5-year follow-up, more persons lived with a partner (+23%) and lived in their own home (+21%). 47% were working vs 11% on entering the programme. Approximately half were satisfied or very satisfied with their quality of life. Having a job in 2013 was associated with a high education level, less cognitive sequelae, having a job in 2008 and no health condition. CONCLUSIONS: The UEROS programme is effective with regard to return-to-work and improvement of autonomy in persons with brain injury, irrespective of length of time from injury.

Diagnosis clinical criteria of sport related concussion: Toward an operational criteria definition in France.

OBJECTIVE: An expert working group was set up at the initiative of the French Ministry of Sports with the objective of harmonising the management of sport related concussion (SRC) in France, starting with its definition and diagnosis criteria. RESULTS: Definition: A clinical definition in 4 points have been established as follows: Concussion is a brain injury: 1) caused by a direct or indirect transmission of kinetic energy to the head; 2) resulting in an immediate and transient dysfunction of the brain characterised by at least one of the following disorders: a) Loss of consciousness, b) loss of memory, c) altered mental status, d) neurological signs; 3) possibly followed by one or more functional complaints (concussion syndrome); 4) the signs and symptoms are not explained by another cause. Diagnosis criteria: In the context of the direct or indirect transmission of kinetic energy to the head, the diagnosis of concussion may be asserted if at least one of the following signs or symptoms, observed or reported, is present within the first 24hours and not explained by another cause: 1) loss of consciousness; 2) convulsions, tonic posturing; 3) ataxia; 4) visual trouble; 5) neurological deficit; 6) confusion; 7) disorientation; 8) unusual behaviour; 9) amnesia; 10) headaches; 11) dizziness; 12) fatigue, low energy; 13) feeling slowed down, drowsiness; 14) nausea; 15) sensitivity to light/noise; 16) not feeling right, in a fog; 17) difficulty concentrating. CONCLUSION: Sharing the same definition and the same clinical diagnostic criteria for concussion is the prerequisite for common rules of management for all sports and should allow the pooling of results to improve our knowledge of this pathology.

[Analysis of the discrimination of the final marks after the first computerized national ranking exam in Medicine in June 2016 in France]. / Analyse de la discrimination des notes aux ECN informatisées de 2016.

INTRODUCTION: The first computerised national ranking exam (cNRE) in Medicine was introduced in June 2016 for 8214 students. It was made of 18 progressive clinical cases (PCCs) with multiple choice questions (MCQs), 120 independent MCQs and 2 scientific articles to criticize. A lack of mark discrimination grounded the cNRE reform. We aimed to assess the discrimination of the final marks after this first cNRE. METHODS: A national Excel® file gathering overall statistics and marks were transmitted to the medical faculties after the cNRE. The mean points deviation between two papers and the percentage of points ranking 75% of students allowed us to analyse marks' discrimination. RESULTS: The national distribution sigmoid curve of the marks is superimposable with previous NRE in 2015. In PCCs, 72% of students were ranked in 1090 points out of 7560 (14%). In independents MCQs, 73% of students were ranked in 434 points out of 2160 (20%). In critical analysis of articles, 75% of students were ranked in 225 points out of 1080 (21%). The above percentages of students are on the plateau of each discrimination curve for PCCs, independent MCQs and critical analysis of scientific articles. CONCLUSION: The cNRE reduced equally-ranked students compared to 2015, with a mean deviation between two papers of 0.28 in 2016 vs 0.04 in 2015. Despite the new format introduced by the cNRE, 75% of students are still ranked in a low proportion of points that is equivalent to previous NRE in 2015 (between 15 et 20% of points).

[Educational assessment of the first computerized national ranking exam in France in 2016: Opportunities for improvement]. / Analyse docimologique des premières Épreuves classantes nationales informatisées (ECNi) de 2016 : propositions d'amélioration.

In June 2016, 8124 medical students in their sixth year of graduation passed the first computerized national ranking exam (CNRE) in France after which they will have to choose what medical specialty they will be practicing all their life. We conducted the first educational assessment of this CNRE according to two criteria: the relevance of the questions and the cognitive domain mainly required to answer these questions. We propose two improvements for the future CNRE: promote student reasoning in the multiple choices questions, reduce to 10 the number of multiple choice questions in the progressive clinical cases and increase by 9 their total number (from 18 to 27), and use a majority of mini-clinical cases for isolated multiple choice questions in order to focus students on reasoning instead of simple knowledge restitution.

A randomized controlled trial on early physiotherapy intervention versus usual care in acute care unit for elderly: potential benefits in light of dietary intakes.

OBJECTIVE: To evaluate effects of early intensive physiotherapy during acute illness on post hospitalization activity daily living autonomy (ADL). DESIGN: Prospective randomized controlled trial of intensive physiotherapy rehabilitation on day 1 to 2 after admission until clinical stability or usual care. SETTING: acute care geriatric medicine ward. PATIENTS: A total of 76 acutely ill patients, acutely bedridden or with reduced mobility but who were autonomous for mobility within the previous 3 months. Patients in palliative care or with limiting mobility pathology were excluded. Mean age was 85.4 (SD 6.6) years. MEASUREMENTS: At admission, at clinical stability and one month later: anthropometry, energy and protein intakes, hand grip strength, ADL scores, and baseline inflammatory parameters. An exploratory principal axis analysis was performed on the baseline characteristics and general linear models were used to explore the course of ADL and nutritional variables. RESULTS: A 4-factor solution was found explaining 71.7% of variance with a factor "nutrition", a factor "function" (18.8% of variance) for ADL, handgrip strength, bedridden state, energy and protein intakes, serum albumin and C-reactive protein concentrations; a factor "strength" and a fourth factor . During follow-up, dietary intakes, handgrip strength, and ADL scores improved but no changes occurred for anthropometric variables. Intervention was associated only with an increase in protein intake. Better improvement in ADL was found in intervention group when model was adjusted on "function" factor items. CONCLUSION: Physical intervention programs should be proposed according to nutritional intakes with the aim of preventing illness induced disability.

Electrical stimulation and muscle strengthening.

OBJECTIVES: To identify the effects of application methods and indications of direct muscle electrostimulation on strength gain. METHODS: Literature review and analysis of articles from Medline database with the following entries: muscular or neuromuscular, electromyostimulation, electrical stimulation, strengthening, strength training, immobilization, muscle dystrophy, bed-rest, bed-bound, knee or hip surgery, postoperative phase, cachexia, sarcopenia, and their French equivalent. RESULTS: Because of its specific muscle recruitment order, different from that of voluntary contraction, direct muscle electrostimulation is theoretically a complementary tool for muscle strengthening. It can be used in healthy subjects and in several affections associated with muscle function loss. Its interest seems well-established for post-traumatic or postsurgery lower-limb immobilizations but too few controlled studies have clearly shown the overall benefits of its application in other indications. Whatever the indication, superimposed or combined electrostimulation techniques are generally more efficient than electrostimulation alone. CONCLUSION: Even though widely used, the level of evidence for the efficiency of electromyostimulation is still low. For strength gains, it yielded no higher benefits than traditional strengthening methods. Its interest should be tested in medical affections leading to major muscle deconditioning or in sarcopenia.

Disability and quality of life in elderly people with diabetes.

To implement preventive policies of disability in older diabetic people, the role of diabetes in the disablement process should be investigated. Diabetes mellitus is consistently associated with a higher prevalence of disability at all states, as well as with a progression in disability states and may be considered as a brake on recovery. This association is partially explained by existing complications, associated conditions (obesity, depression, arterial hypertension) treatment burden, and other social characteristics (lower income, lower educational level). Finally, in the disablement process, the role of altered muscle metabolism due to diabetes, aging, nutrition and sedentary lifestyle may represent a major target for interventions to improve functions and potentially activities in elderly people.

Muscle phosphocreatine post-exercise recovery rate is related to functional evaluation in hospitalized and community-living older people.

OBJECTIVE: to explore muscle mitochondria function with respect to age, functional status and nutrition in community-living and recovering hospitalized older subjects. MEASUREMENTS: subjects were assessed for nutrition, hand-grip strength, 10-meter gait time, a modified timed get-up-and-go test and activities of daily living score (ADL). 31P magnetic resonance spectroscopy (31P MRS) was used to assess the initial rate of post-exercise phosphocreatine recovery (ViPCr) for mitochondrial function evaluation in 25 hospitalized older subjects (86.1 + 5.3 y) and in 25 community-living younger ones (74.5 + 6.2 y). RESULTS: in multiple linear regression, longer time on the get-up-and-go test was independently associated with lower values of ViPCr (p = 0.008). For all subjects and in the 8 patients unable to perform this test, ViPCr was negatively correlated with the ADL score (respectively p < 0.001 and p = 0.025). CONCLUSION: particularly in hospitalized and frail older subjects, muscle mitochondrial function was related to the global physical functional assessment.

Kinematic and electromyographic analysis of rising from a chair during a "Sit-to-Walk" task in elderly subjects: role of strength.

BACKGROUND: With aging, the deterioration of the ability to rise from a chair constitutes a major source of disability and a factor contributing to the loss of autonomy. The aim of this study was to describe kinematic and electromyographic characteristics of rising from a chair during a Sit-to-Walk task and to investigate the relationships between lower limb muscle strength and Sit-to-Walk characteristics. METHODS: Twenty-four healthy elderly subjects (mean age: 73.8 (6.4) years) were included. The task analyzed consisted in standing up and taking a step. Kinematic data were obtained using a 3D motion analysis software. Surface electromyography of eight lower limb muscles was recorded. Isokinetic strength of ankle plantar flexor and knee flexors and extensors was evaluated. FINDINGS: The Sit-to-Walk was divided into four phases. For 19 subjects, this task can be considered as a continuum with an overlap of the phases. In comparison with the Sit-to-Stand description, the Sit-to-Walk transition phase, which combined trunk flexion and knee extension, appeared longer in order to increase the body forward transfer for gait initiation. In most cases, the tibialis anterior and peroneus longus muscles were first activated. The isokinetic strength of the knee extensors was negatively correlated with the amplitude of trunk flexion and the knee flexors/extensors torque ratio was correlated with the length of this phase. INTERPRETATION: Characterization of Sit-to-Walk movement provides information about the ability to rise from a chair. In the elderly, a better knowledge of its determinants could lead to improve strategies for rehabilitation of this critical task.

No beneficial effect of bracing after anterior cruciate ligament reconstruction in a cohort of 969 athletes followed in rehabilitation.

OBJECTIVE: Compare the clinical outcomes of different knee braces in the early phase of rehabilitation after anterior cruciate ligament reconstruction (ACLR) in athletes. MATERIALS AND METHODS: We conducted a retrospective database study of athletes during early rehabilitation in a tertiary referral hospital between 1 February 2008 and 30 October 2010 after ACLR using bone patellar tendon bone (BPTB) or hamstring autograft. Differences in mid-patellar knee circumference, pain, and range of motion were assessed at admission. All patients followed the same rehabilitation protocol. Patients who had complications preventing them from following the assigned rehabilitation program were analyzed separately. Patients who completed their rehabilitation program were also assessed for thigh muscle atrophy, extension deficit≥2°, quality of walking, PPLP1 and subjective IKDC scores. The type and frequency of complications and their frequency was documented. The above-mentioned parameters were analyzed in 3 different groups: rigid brace in full extension, articulated brace (0°-90° for first 3 weeks then 0-120°) or no brace. RESULTS: The analysis included 969 patients. Rehabilitation started at 4.5±2.9 days after surgery and ended at 32.4±3.0 days postoperative. At the beginning, flexion was lower in patients with a rigid brace (P<0.01). There was no difference in the frequency or severity of complications between the three study groups, nor was there a significant difference in the clinical outcomes listed above. CONCLUSION: Postoperative bracing after ACLR has not beneficial effect on clinical outcomes and the complication rate. Patients who wore the rigid brace had limited flexion early on.

Fatigue after spinal cord injury.

OBJECTIVES: To identify variables increasing fatigue following spinal cord injury (SCI) and their functional consequences. METHODS: A search of the Medline and Reedoc databases with the keywords SCI, fatigue, intrinsic muscular fatigue, chronic fatigue, aging, training, electrostimulation, quality of life and the same words in French. RESULTS: Two kinds of fatigue are identified following SCI. Intrinsic fatigue in muscles totally or partially paralysed at the level of or below the spinal cord lesion; this peripheral fatigue is due to denervation, total or partial loss of motoneurons, or histological and metabolical changes in muscle; it is well-defined by electrophysiological technology; spasticity and spasms have little influence on its development; it is reversible in part with long term electrostimulation, but at this time, electroneuroprosthetic techniques do not reduce the excessive energetic cost to stand up and walk. Chronic fatigue appears in the long term following SCI; it is linked with aging, physiological, and psychological deconditioning; some data point to chronic fatigue after SCI similar to post-polio syndrome and chronic fatigue syndrome, which may explain the central nature of the fatigue; training programs could be useful in delaying this chronic fatigue and as a consequence, increasing the latent quality of life. CONCLUSION: Muscular intrinsic fatigue after SCI is always of a peripherical nature in muscles partially or totally paralysed. Chronic fatigue during aging greatly decreases quality of life. Both intrinsic and chronic fatigue could be anticipated by electrostimulation technique on the one hand and long term training on the other.

Post-acute referral of stroke victims in a French urban area: Results of a specific program.

OBJECTIVE: The main objective of this study was to describe the distribution of referrals offered to patients assessed in the "Post-Acute Stroke program" of Bordeaux University Hospital (France). This program was developed in 2008 to organize the dispensation of care in rehabilitation units specialized in neurological diseases. MATERIAL AND METHODS: This was a single-centre observational study. Between July 2008 and December 2012, data on the number of stroke patients hospitalized at the Bordeaux University Hospital and their post-acute referral were collected from the local hospital discharge database. Some of these patients were assessed by Physical Rehabilitation and Medicine physicians participating in the program. Proposed and actual referrals, time from admission to assessment and functional status were also collected. RESULTS: Among 4189 stroke patients, 1465 (35%) survivors were assessed, of whom 932 (22.2%) were discharged to inpatient rehabilitation facilities. There were no patients discharged to this type of unit without an assessment. Among the 1465 patients who were assessed, 57.2% were referred to specialized rehabilitation units, 6.3% were discharged to non-specialized rehabilitation units and 26% returned home directly. The median total length of stay in acute units varied from 10 to 15days depending on referral orientation. CONCLUSION: Patients that were assessed were more likely to be transferred to specialized rehabilitation units than to non-specialized rehabilitation units. The Post-Acute Stroke program has the particularity of combining private and public specialized rehabilitation units in a common collaborative referral system while retaining the control and flexibility of personalised referral for each patient in the light of local care availability.

Early changes in isokinetic lower limb muscle strength in recovering geriatric subjects on the basis of nutritional status.

BACKGROUND: In older people, the decrease in muscle mass and strength has a bad effect on functional status. Malnutrition and lack of physical activity exacerbate this phenomenon. OBJECTIVE: The main purpose of this study was to estimate isokinetic lower limb muscle strength in recovering older subjects on the basis of nutritional status. DESIGN: Twenty-eight elderly subjects hospitalized for an acute event (85.8 +/- 6 years), including 16 malnourished, were enrolled in this study when clinically stable (T0). Re-assessment at one-month was performed in nine after oral supplementation and conventional physiotherapy (T1). The Maximal Peak Torque (MPT) of the ankle plantar flexors was estimated in concentric mode at 30 and 60 degrees /s. The MPT of the knee flexors and extensors was evaluated in the same mode at 30 degrees /s, 60 degrees /s and 120 degrees /s. All patients underwent a nutritional examination with anthropometric measures, dietary intake survey, biochemical indexes and determination of the medial gastrocnemius volume by magnetic resonance imaging. RESULTS: At T0, whatever the muscle group tested (except at 120 degrees /s for the knee), the MPT appeared significantly lower in the malnourished group. At T1, the increase in MPT (plantar flexors) in malnourished patients was greater at 60 degrees /s (+23.8 %) than at 30 degrees /s (+14.8 %). Correlations between MPT and nutritional parameters were observed in the malnourished group only at T1 and in the normal-nourished group. CONCLUSION: Isokinetic assessment seems to be a pertinent method to estimate lower limb muscle strength in older and frail subjects. Early modifications in strength were observed in malnourished patients who received oral supplementation and physiotherapy.

[Decision making and executive function in severe traumatic brain injured patients: validation of a decision-making task and correlated features]. / Prise de décision et fonctions exécutives chez le patient atteint de traumatisme crânien grave: validation d'une tâche de prise de décision et facteurs corrélatifs.

OBJECTIVE: At the chronic stage, severe traumatic brain injured (TBI) patients experience difficulty in making decisions. Several studies have demonstrated the involvement of the prefrontal cortex, in particular the orbitofrontal region, in decision-making. The aim of the present study was to validate a decision-making task in this population and to ascertain whether the components of their dysexecutive syndrome may affect their decision-making and lead to difficulties for social rehabilitation. PATIENTS AND METHODS: Fifteen TBI patients and 15 controlled subjects matched for age, sex and years of education were assessed by a battery of executive tests (GREFEX) and by the gambling task (GT). RESULTS: The TBI subjects performed significantly worse than the controlled group in five out of six GREFEX tests. The TBI choices are significantly more disadvantageous than the choices of the control group when considering the three last blocks of 20 cards of the GT. The GT total score correlated significantly with execution time of the Stroop interference condition and the Trail Making Task B, as well as with the two measures (correct sequence span and number of crossed boxes) of the double condition of Baddeley's task. CONCLUSION: We postulate that executive functioning (supervisory attentional system) influence performance in the gambling task through mechanisms of inhibitory control, divided attention and working memory. Thus, this task seems to be determined by multiple factors; the process of decision-making may depend on frontal integrity.

Functional and metabolic early changes in calf muscle occurring during nutritional repletion in malnourished elderly patients.

BACKGROUND: Metabolic alterations in skeletal muscle associated with malnutrition and the potential reversibility of such alterations during refeeding are not fully understood. OBJECTIVE: We characterized early changes in muscle during refeeding in malnourished, hospitalized elderly subjects. DESIGN: Muscle function, metabolism, and mass were evaluated in 24 clinically stable patients (11 were malnourished) by using isokinetic plantar flexor torque measurements and nuclear magnetic resonance (NMR) imaging for medial gastrocnemius mass assessment and 31P and 13C NMR spectroscopy for inorganic phosphate (Pi), phosphocreatine, and glycogen quantitation. RESULTS: Malnourished subjects had lower muscle mass (P < 0.02) and tended to have lower strength than did control subjects. In malnourished subjects, muscle strength increased after refeeding (P < 0.01) whereas muscle mass was unchanged. The ratio of Pi to ATP was lower in malnourished than in control subjects (P < 0.001) and increased during refeeding (P < 0.01). The mean ratio of phosphocreatine to ATP was lower in malnourished than in control subjects (P < 0.01) and increased to control values after refeeding. Muscle glycogen showed a scattered distribution for malnourished subjects; the mean value did not differ significantly from that of control subjects, either at baseline or after refeeding. CONCLUSIONS: The lower ratio of phosphocreatine to ATP in malnourished subjects could have resulted from either lower total muscle creatine or reduced oxidative capacities. High or normal glycogen associated with a low Pi-to-ATP ratio in malnourished subjects suggested preferential use of lipid over carbohydrate for energy supply, which is known to reduce muscle performance. The data suggest that normalization of muscle metabolite content after refeeding improves muscle strength in malnourished subjects.

[Non verbal communication abilities in severe traumatic brain injury]. / Compétences de communication non verbale des traumatisés crâniens graves.

OBJECTIVE: Discursive abilities of severe brain injured patient are always impaired: loss of flexibility, lack of cohesion and coherence, often more elliptic. We know few about nonverbal competencies during discourse. The objective is to verify nonverbal abilities of these patients by pragmatic analysis. METHODS: Four men were examined more than 7 years after severe traumatic brain injury. Nonverbal Prutting and Kirchner Pragmatic Protocol (1987) were done allowing to a qualitative and quantitative measurement of paralinguistic behaviour: prosody and quality of speech, facial expression, posture, gaze, gesture. Two conditions were recorded: dual (descriptive discourse) and group (conversational discourse). Associated impairments such as cognitive and dysexecutive functioning were also investigated. RESULTS/DISCUSSION: Impoverishment (loss of ability) or impaired inadequacity was observed in all patients. Paralinguistic competences of conversational discourse was worse than descriptive one. Facial expression, gaze functioning, referential gesture were more often impaired. Maladjustment could be interpretated in reference with dysexecutive syndrome. CONCLUSION: In spite of the lack of information about the range of normal pragmatic behaviour, it seems that brain injured patients have shown poor nonverbal abilities during discourse. Rehabilitation training of communication skills would integrate this fact in order to improve interactivity and social relationship.

[Botulinum toxin and traumatic brain injury]. / Toxine botulique et traumatisme crânien.

Botulinum toxin is a successful focal spasticity therapy. The aim of this article is to study the data of the literature concerning its utilisation in traumatic brain injured patients, whom motor and tonus disturbances are polymorphic, in their clinical presentation as well as in their evolution. Although there are few studies concerning its utilisation in such patients, none of them being controlled, its use seems interesting in focal spasticity treatment. It can contribute to improve functional abilities and comfort for these patients.

[Botulinum toxin A and musculoskeletal pain]. / Toxine botulique A et douleurs musculosquelettiques.

INTRODUCTION: Relaxant muscle properties and pain relieve effectiveness in neurological spasmodic disorders of botulinum toxin A (BTXA) suggested its relevance to relieve musculoskeletal pain. The aim of this article was to collect literature data and to assess the different analgesia indications of BTXA proposed in the treatment of musculoskeletal pains. METHOD: The international literature was carried out with the Medline data bank using keywords toxin and pain. Only clinical trials have been analysed. RESULTS: Three hundred and seventeen articles were collected and 12 clinical trials were retained. They are focused on 4 chronic diseases, neck pain, tennis elbow, Piriformis syndrome and low back pain. Results of the 6 chronic neck pain studies are contradictory and emphasize the difficulty to display a satisfactory analgesia effect of BTXA in this indication. Results of the studies concerning other indications (tennis elbow, Piriformis syndrome and low back pain) seem to be more effective and clinically pertinent. DISCUSSION: Analgesia BTXA effect seems to be conditioned by the presence of an objective muscular spasm or stringy disease inducing musculoskeletal pain. CONCLUSION: The first data concerning use of BTXA to treat musculoskeletal pains are few and are worth specifying by other studies.

Acquired deforming hypertonia and contractures in elderly subjects: definition and prevalence in geriatric institutions (ADH survey).

OBJECTIVE: By proposing a new terminology (acquired deforming hypertonia or ADH) and a new definition for contractures, the main objective of this study was to establish their prevalence among institutionalized elderly patients. Secondary objectives were to analyze the negative impact of ADH and collect the opinions of clinicians on the possible treatments available. METHODOLOGY: A multicenter cross-sectional study was conducted among residents of 39 geriatric institutions (29 EHPAD and 10 USLD). All subjects presenting at least one ADH were surveyed over a one-week period. RESULTS: Among 3145 observed patients (mean age 88.9±9.7 years) 22% (n=692) presented at least one ADH. In average, each patient presented 4.4±3.2 ADHs. Negative consequences on self-care, nursing and difficulties in getting dressed were most frequently observed. Only 25.4% of clinicians considered the ADH to be potentially reversible. Physical therapy was the therapeutic option most frequently chosen over medication and surgery. CONCLUSION: This study confirms the important prevalence of ADH among elderly institutionalized patients. Consequences on the level of dependence were significant. It seems relevant to elaborate hierarchical therapeutic strategies in order to counter these disorders and the fatalism that ensues.
