Construction and feasibility study of the SOFMER Activity Score (SAS), a new assessment of physical and cognitive activity.

OBJECTIVES: For hospitalizations in rehabilitation centers (RCs) in France, the quantification of healthcare givers' activity is based on the dependency of the patients, defined as a total or partial inability to perform activities required for daily living without help. The tools currently used to quantify dependency are not sufficiently precise. Here we describe the construction of a new tool, the SOFMER Activity Score (SAS scoring), which allows for a good description of the level of activity of patients hospitalized in RCs, and a feasibility study of the tool. METHODS: After a study group proposed the first version of the SAS, the validity of its content was studied by the Delphi consensus method: 26 physicians or healthcare professionals known for their expertise in PMR responded to the first round. The feasibility study was prospective and involved multi-site professionals. Data related to the SAS determined by a multidisciplinary team were collected and compared to the Activité de la Vie Quotidienne (AVQ) scale, which is administered to all patients and included in medical and administrative data. RESULTS: We included 81 patients in the feasibility study. The mean (SD) time to obtain the SAS was 4.5 (3.3) min. For 97.5% of scorings, the participating professionals judged that the SAS was compatible or fairly compatible with clinical practice. The internal structure of the SAS scale seemed better than that of the AVQ scale, for which the present study confirmed a floor effect for all items. CONCLUSIONS: The SAS allows for measuring the level of physical and cognitive activity of a patient hospitalized in an RC. If validation studies for the SAS, exploring its reliability, construct validity or criterion validity, confirm the tool's good metrological qualities, the SAS will allow for a good quantification of the burden of care.

Oral anticoagulant treatment - evaluating the knowledge of patients admitted in physical medicine and rehabilitation units.

INTRODUCTION: While numerous therapeutic education programs exist in physical medicine and rehabilitation (PM&R), they rarely concern pharmacological treatments. Nevertheless, drugs prescribed during a hospital stay can have a significant risk of adverse events. Vitamin K antagonists (VKA) are among them. OBJECTIVE OF THE STUDY: To assess patients' knowledge on their oral anticoagulant treatment before their hospital discharge. METHODS: Fifty patients were enrolled in this prospective, monocenter study. Their level of knowledge was assessed by a semi-structured interview between the pharmacist and the patients and/or their caregivers. RESULTS: Seventy percent of patients were able to give the name of the drug they were taking, 82% could explain its effect and finally, 24% of patient knew their INR target values. Twenty-two percent of patients were able to describe the symptoms in case of overdose and what to do in that case. Forty percent of patients were aware of food interactions and 60% of self-medication risks. The patient's knowledge and behavior acquired during their hospital stay are not enough to guarantee a safe treatment management upon discharge. Based on this study, therapeutic patient education sessions were implemented. CONCLUSION: These results suggest that specific drug therapy management sessions should be developed as part of PM&R's therapeutic education programs for patients.

[Three dimensional gait analysis and controlling spastic foot on stroke patients]. / Intérêt de l'analyse tridimensionnelle de la marche, dans la prise en charge du pied spastique.

INTRODUCTION: The purpose of this work is to assess the interest of three dimensional gait analysis in measuring the effect of orthesis and of selective tibial neurotomy without visual analysis. METHOD: After clinical examination, gait in the two groups was recorded by a three dimensional motion system (Vicon-Oxford Metrics) with free velocity. The gait of ten stroke patients was compared bare-foot and with ankle-foot orthesis. The gait of nine stroke patients was compared bare-foot before and six month after selective tibial neurotomy. Kinematics data were studied in the sagittal plane, and muscular electrical activity was detected on the affected side by a ten-channel telemetry system using surface electrodes. An analogic visual scale ( EVA) was used by the patient, to assess discomfort during walking. RESULTS: In the "orthesis" group, calf spasticity was 2.5 on the Ashworth scale. With ankle-foot orthesis, the walking discomfort on EVA was significantly reduced from 4.25 to 1.16. Gait speed increased significativelly at 0.42 m s(-1) to 0.59 m s(-1). In swing phase, equinus disappeared. In stance phase equinus and recurvatum were controlled, anterior pelvic tilt decreased and hip extension increased. In the "neurotomy" group, 6 months after the tibial neurotomy, calf spasticity decreased from 3.4 to 0. The walking discomfort on EVA, was significantly reduced from 5.97 to 3.6. Gait speed increased from 0.51 m s(-1) to 0.54 m s(-1). Ankle dorsiflexion on the affected side, was possible during stance for five patients and residual motricity was released during swing phase for two patients. Stance knee recurvatum was corrected in five patients. CONCLUSION: Three dimensional analysis specifies the functional gait disability in stroke patients. It specifies the degree of correction provided by orthesis or tibial neurotomy in the various gait cycle phases and the impact on the superior joints.

[3D preliminary analysis gait in stroke patients: knee flexion in compensatory strategies]. / Analyse préliminaire 3D de la marche de l'hémiplégique: rôle de la flexion du genou dans la stratégie de récupération fonctionnelle.

OBJECTIVE: The aim of this preliminary study was to assess strategies of walking a stride in stroke patients with spastic right hemiplegia. MATERIAL AND METHODS: Gait was recorded in 3D in seven patients without other locomotion disorders. Kinematics data were studied only on the sagittal plane. The position and trajectory markers on the right side were studied during the swing phase in comparison with static standing position. Results were confronted with angular data. RESULTS: Three walking models were defined: 1) near normal gait with normal mobility in the knee; 2) gait with hicking while the flexion of the knee was reduced; 3) gait with a "talus" foot without motor recovery necessitating a pendular movement. DISCUSSION: The second pathological group was characterized with insufficient flexion in the knee in lifting the foot from the floor. In this group, patients adopted a compensation strategy with hicking in making the stride without touching the floor. We raised the question of limiting this adaptive strategy in order to enhance their remaining mobility. CONCLUSION: A 3D strategy gait analysis, before therapeutic choices, seems to confirm the value of analysing kinematic data in stroke patients with hemiplegia. The amplitude of knee mobility and hip compensation strategy can be specifically studied to improve the effectiveness of therapeutic strategies (orthesis, selective tibial neurotomy, botulinum toxin).

[The development of gait in the hemiplegic patient after selective tibial neurotomy]. / Etude de l'évolution de la marche chez le patient hémiplégique après neurotomie tibiale sélective.

BACKGROUND AND PURPOSE: Spastic Foot may constitute a severe functional deficit leading to instability in stance and inappropriate prepositioning of the foot for its initial contact with the ground. The purpose of the study was to analyze the results of selective tibial neurotomy on gait. METHOD: After clinical examination of nine hemiplegic patients, gait was recorded before surgery and six months after. Three-dimensional bilateral kinematic data were obtained with a motion measurement system (VICON), and muscular electrical activity on affected side was detected with surface electrodes. The patient walked barefoot, with his free velocity, on a ten meter track in the lab. An analogic visual scale was used by the patient to evaluate gait discomfort. RESULTS: After neurotomy, triceps surae spasticity decreased and passive motion of ankle increased. Gait comfort was better, claw toes and sore skin disappeared. Kinematics data were modified by neurotomy in all patients. On the affected side, ankle dorsiflexion improved during stance for five patients and residual motricity improved during the swing phase for two patients. Stance knee hyperextension was corrected in the five patients. EMG data: Selective tibial neurotomy caused disappearance of triceps surae peak activity at the beginning of the stance phase and at the end of swing phase. The time activity of the other muscles did not change. CONCLUSION: Selective tibial neurotomy can cure foot deformity and modify ankle motion during gait. It corrects knee hyperextension during stance phase.
