e30 SOFMER 2016 / Annals of Physical and Rehabilitation Medicine 59S (2016) e25–e33 The factors of good compliance are continence and auton- omy regarding the introduction of the catheter. Nevertheless, self-catheterization can be difficult because of the usual short- comings associated with bladder and sphincter disorders (motor, sensory...). We found only one study about one adaptive equipment to facilitate the gesture for monoplegic patients. Observations This case report concerns a 53-years-old man, left brachial amputated in 1987 because of a motorbike accident asso- ciated with primitive progressive multiple sclerosis since 1996. He has an overactive bladder syndrome and dysuria because of a detru- sor sphincter dyssynergia and overactive detrusor. Treatments by alpha bloquants then TENS on the tibial posterior nerve and finally neuromodulation of the posterior sacral roots did not succeed. The indication of self-catheterization was chosen and the patient’s education was organized in Physical Medicine and Rehabilitation unit in University Hospital of Rangueil. The team of therapists has manufactured adaptive equipment to enable the learning of intermittent self-catheterization despite his amputation. It consists in the realization of a thermo-formed plastic penile support, with a central channel to support the penis and a curved base on both sides for holding the device between the thighs. It was a success and the patient was able to independently urinary catheterism with one hand while the device correctly maintained his penis. Discussion/Conclusion Three months later, he no longer needed this assistance. To conclude, it can be conclude that a multidisciplinary management allowed a monoplegic patient to acquire the self- catheterization technique, avoiding him to undergo surgical treatment.

E-mail address: marie laberge@ssss.gouv.qc.ca (M. Laberge-Malo) Objective Toe filler combined to ankle-foot orthosis (AFO) can be used to improve gait after a partial foot amputation. The AFO supports the plantar aspect of the foot, and the toe filler gives a longer lever arm that helps for pivoting over the lost metatarsals. However, the AFO type can influence gait parameters. The objective of this study case was to evaluate the effect of pros- thesis with toe filler combined to: – an articulated AFO; – a fixed carbon-fiber AFO on gait. Patients and methods A gait analysis was practiced on a 20-year- old male with a partial foot amputation. Kinematic and kinetic data during walking, gait efficiency (Energy Expenditure Index), and postural control were evaluated in both conditions. Results An improved ankle power was observed at toe-off with the fixed carbon-fiber AFO. Moreover, spatiotemporal gait param- eters were more symetrical with the fixed carbon-fiber AFO. Gait efficiency was higher with the fixed carbon-fiber AFO compared to the articulated one. Discussion/Conclusion The fixed carbon-fiber AFO improves ankle kinematic and kinetic during walking and results in an improve- ment of walking efficiency in this participant with partial foot amputation.

E-mail address: fanette.chassagne@emse.fr (F. Chassagne) Objective Compression bandages are commonly used in the treatment of some venous or lymphatic pathologies. The success of the treatment relies on the applied pressure, which depends on several parameters, especially the bandage properties but also patients’ morphology. A previous experimental study showed that considering only patient’s morphology and bandage elastic properties were not suffi- cient to explain interface pressure distribution. However, these two parameters are the only one taken into account in Laplace’s Law, current standard method to explain interface pressure distribution. The objective of the study is to characterize and model compression bandages pressure generation mechanisms. Material and methods A patient-specific numerical simulation of 4 bandages application [Biflex ® 16 and Biflex ® 17 (Thuasne) applied with 2 and 3 layers on the leg] was developed for 5 sub- jects. The inputs of this simulation are the subjects’ morphology, the bandage’s and soft tissues’ elastic properties and the application technique. The results of this simulation were then confronted to the experi- mental results and pressure values computed with Laplace’s Law: P = nT/r, with P the pressure [N/mm 2 ], n the number of layers, T the bandage tension [N/mm] and r the local radius of curvature [mm]. Results The numerical simulation provides the complete pres- sure distribution over the leg but also considers the deformations of the leg, induced by bandage application. The comparison with the results given by Laplace’s law highlighted the influence of these leg geometry changes on the applied pressure. However, the 4 parameters considered in this simulation (leg morphology and deformations, bandage elastic properties and application technique) are not sufficient to completely explain pressure generation, and differences with the experiments still per- sist. Discussion/Conclusion Numerical simulation still needs to be enriched to consider other parameters which may impact interface pressure such as bandage to bandage interaction for example.
