Asymétries chronométriques, cinétiques et cinématiques de l''initiation de la marche chez un sujet hémiplégique

OBJECTIVE: To investigate the temporal, kinetic and kinematic asymmetry of gait initiation in one subject with hemiplegia with an equinus varus foot. MATERIAL AND METHODS: A kinetic analysis with two AMTI force plates and a kinematic analysis with an ELITE optoelectronic system of gait initiation were performed in one subject with hemiplegia. RESULTS: The duration of the gait initiation phases was asymmetrical. The monopodal phase was shorter when the affected lower limb was supporting than when the healthy one was supporting. The propulsion resulted from the force exerted on the healthy lower limb. The distribution of body weight on the lower limbs was asymmetrical. Body weight support was more important on the healthy side than on the affected side. Maximal extension of the ankle on the hemiplegic side occurred during the swing phase. Ground clearance was increased by elevating the knee higher on the affected side than on the healthy side during the swing phase. Initial contact with the floor was performed with the foot flat on the affected side. CONCLUSION: This preliminary study has shown that gait initiation in one subject with hemiplegia was asymmetrical in kinetics and kinematics. The results concerning kinematics have not been reported previously for gait initiation in subjects with hemiplegia. The study of gait initiation should allow for better understanding postural and movement control strategies developed by patients with hemiplegia.     

Évaluation de l'efficacité des injections locorégionales de buflomédil par la mesure de TcPO2 au cours du syndrome épaule-main de l'hémiplégique

The authors have evaluated the efficiency of loco-regional injections of buflomedil in the shoulderhand syndrome in hemiplegic patients by using a clinical score and the measure of transcutaneous pression of oxygen (TcPO₂) at wrist. The study was carried out in 15 patients who were given three injections of 100 mg on D1, D3, D5, five weeks post stroke. They were evaluated on D12 and D26 and their conditions were compared with five hemiplegic untreated patients. The study confirms the clinical efficiency of the treatment as regards pain and vasomotor disorders in algodystrophy. TcPO₂ data confirms the clinical improvement in vasomotor disorders. Indeed TcPO₂ initial decrease reflecting the local hypoxia notably improves thanks to treatment without returning to normal.     

Apport de l’exercice physique et du régime dans la prise en charge de la gonarthrose chez l’obèse

Objective

Our objective was to determine whether exercise and weight loss are more effective either separately or in combination, in improving pain and physical function in obese adults with moderate knee osteoarthritis (OA).

Patients and methods

Forty-five obese adults, with a body mass index greater than 35 kg/m² or 30 ≤ BMI < 35 associated to at least one cardiovascular risk factor, suffering from knee pain with evident radiographic signs of knee OA, were involved in our study. All patients were evaluated at baseline and at the end of the study. The assessment parameters were weight loss, the bioelectric impedance analysis, pain, six-minute walk distance, cardiovascular parameters, and muscular strength. The physical function was measured with the Womac and the Lequesne indexes. Patients were randomized into four groups, a control group (G1), exercise only group (G2), diet plus exercise group (G3) and diet only group (G4).

Results

There was no difference between the four groups at baseline. Significant improvement of function (Womac) was noticed in groups performing exercise only (G2) (26 %), diet plus exercise (G3) (37,89 %) and diet only (G4) (18,34 %). We also noticed an improvement in pain in G2 (p = 0.04), G3 (p < 0.001) and G4 (p = 0.02). The improvement of quadriceps strength was noted only in G2 (p = 0.01) et G3 (p = 0.001) without any change in control group and diet only group (G4). The improvement of cardiovascular parameters was observed only in G2 and G3. Weight loss, decreased BMI and waist circumference was more important in diet plus exercise group (G3).

Conclusion

The combination of weight loss and exercise provide better improvements in physical function and pain in obese adults with knee OA compared with either intervention alone. Exercise used alone or associated to dietary provides better improvements in physical capacity and muscle strength.     

Évaluation de l''attitude vis-à-vis des personnes handicapées des étudiants en médecine de 3 et 4 année par le questionnaire « Attitude towards disabled persons ». Effets de l''enseignement théorique et de stages dans les services de médecine physique et réadaptation

Modifications of the medical curriculum have included a compulsory course on disability. OBJECTIVE: To determine whether attendance in a course on disability and/or rotations in physical medicine and rehabilitation departments modify the attitude of medical students towards disabled people. METHODS: All third- and fourth-year students completed a translated version of the ATDPb. This questionnaire rates items evaluating attitude towards disabled people on a 6-point scale (minimum 0; maximum 180). Retro-translation was performed to control the translation. During the second year, all students had attended a general course in ethics. Fourth-year students had attended a 17 hours course on disability, and 21 of 78 had spent 9 weeks in the physical medicine and rehabilitation department. The study compares fourth-year students to third-year students, considered as controls, and students having spent a rotation in the physical medicine and rehabilitation department to others. RESULTS: The mean score of all students was 108.86+/-15.84 (73-160) on the ATDP scale. Males and females did not differ significantly, and the score did not change from that before the course on disability (109.95+/-14.98 vs 107.6+/-16.65, P=0.23) nor after a rotation in the physical medicine and rehabilitation department (113.52+/-11.42 vs 108.54+/-16.03, P=0.14). CONCLUSION: Development and validation of scores that would fit better to the European cultural context would be useful. The present method of theoretical courses and rotations do not improve the attitude of students towards disabled people and should be modified if this objective is to be achieved.     

Les textes réglementant l’activité en soins de suite et de réadaptation du décret du 9 mars 1956 aux décrets du 17 avril 2008. Place de la médecine physique et de réadaptation

In France, inpatient care is provided in three different sectors: "medicine, surgery and obstetrics", "follow-up care and rehabilitation" (soins de suite et de réadaptation=SSR) and "long-term care". Physical medicine and rehabilitation is involved mainly in SSR. As of April 2008, there are new regulations aiming to improve prior texts, to implement rules that will be identical for public and private sectors and to prepare for the new payment-by-the-act funding system (in place of the prior global funding). Now, all SSR structures have a common general basis in terms of purpose and means and specific rules for various specialties. For example, coordination of a multidisciplinary team in specialized facilities dealing with musculoskeletal and nervous system disorders must be conducted by a physical medicine and rehabilitation (PMR) specialist. Patient admission criteria still need to be defined, as does the assessment of therapeutic objectives. The expertise of SSR facilities is recognized by the possibility of direct admission from home for ambulatory patients. Nevertheless, many specifics are missing in these new decrees. These specifications will be elaborated on a regional basis, in future endeavours within regional healthcare organizations.     

La prééclampsie: Physiopathologie et perspectives de dépistage précoce

Preeclampsia is a complication of pregnancy characterized by hypertension, edema and proteinuria, beginning after 20 weeks of gestation. Six percent of the pregnant women in North America develop this disease, which is associated with increased morbidity and mortality for the mother and her baby. The physiopathology remains uncertain despite many research efforts. Actual hypotheses seek to explain the vasospasm that characterizes the disease. Among the many factors influencing vascular reactivity and possibly implicated are: the renin-angiotensin system, prostaglandins, progesterone and its metabolites, calcium, magnesium, digoxin-like immunoreactive substance(s), auricular natriuretic factor, substances secreted by platelets and leukotrienes. Prevention of the disease is limited by the absence of a biological or clinical marker with good sensitivity and appropriate specificity. Many biochemical or hematological parameters have been reported: uric acid, calcium, magnesium, proteinuria, blood iron, hematocrit, platelet count, antithrombin III, estrogen and progesterone. The combination of several tests could be superior to the use of each test individually, providing a better sensitivity and improving the positive predictive value. With early detection, new therapies for the prevention of the disease could be experimented on the higher risk women before the apparition of clinical symptoms or signs. Furthermore, those tests could be used in the study of the pathophysiology and in the choice of the best therapy.     

Intérêt du simulateur de conduite pour la reprise de la conduite automobile en situation de handicap

AIMS: To evaluate the value of our driving simulator in deciding whether or not to allow patients with physical and/or cognitive deficits to resuming driving and to analyze whether or not the medical expert's final decision is based more on the results of the driving simulator than those of the neuropsychological examination. METHODS: One hundred and twenty-three patients were evaluated with the driving simulator. Thirty-five of those with cognitive deficits also underwent a neuropsychological examination prior to the medical expert's decision on driving aptitude. In cases of uncertainty or disagreement, a driving assessment in real conditions was performed by a driving instructor. RESULTS: In cases of physical handicap, the medical expert's decision concurred with that of the occupational therapist. For brain-injured patients, there was a significant correlation between the neuropsychologist's opinion and that of the occupational therapist (kappa=0.33; P=0.01). However, the sensibility and specificity were only 55 and 80%, respectively. The correlation between an occupational therapy decision based on the driving simulator and that of the medical expert was very significant (kappa=0.81; P<0.0001) and the sensibility and specificity were 84 and 100%, respectively. In contrast, these values were lower (63 and 71%, respectively) for the correlation between the neuropsychologist's opinion and that of the medical expert. CONCLUSION: Our driving simulator enables the danger-free evaluation of driving aptitude. The results mirror an in situ assessment and are more sensitive than neuropsychological examination. In fact, the neuropsychologist's opinion often is more negative or uncertain with respect to the patient's real driving aptitude. When taking a decision on a patient's driving aptitude, the medical expert is more inclined to trust the results of the driving simulator.
