Ependymomas are a rare malignant neoplasm. Multifocal intradural extramedullary anaplastic ependymomas are even more of a rare entity with much of the current knowledge derived from case reports. We presented a case of a multifocal intradural extramedullary anaplastic ependymoma with intracranial involvement at presentation.

A 53-year-old male presented with urinary symptoms. Magnetic resonance imaging revealed two lesions along the spinal cord and two lesions, intracranially. Histopathological examination was consistent with the World Health Organization grade III anaplastic ependymoma. The patient was treated with the gross total resections of spinal cord lesions, followed by radiation therapy to the resection cavities and intracranial lesions. At the 10-month follow-up visit, he reported almost complete resolution of symptoms, and magnetic resonance imaging revealed no recurrence.

Despite their rarity, ependymomas should be considered as the differential diagnosis when evaluating spinal tumors. Gross total resection followed by targeted radiotherapy appears to be an effective treatment modality for high-grade lesions.

Ankle Foot Orthosis (AFOs) are frequently prescribed in the management of drop-foot patients. However, few studies have examined the benefits of different design of AFOs with elements added to AFOs like dampers or springs as an actuator, stored energy at the first half of the stance phase and restored at the entire swing phase.The objective of this study was to investigate the efficacy of articulated AFO with Hydra pneumatic damper, in biomechanical characteristic of drop foot patients.

Ten drop foot patients were recruited for this study, walked at self-selected comfortable speed. A three-dimensional motion analysis, were used for obtaining kinetic, spatio-temporal and kinematic gait parameters

The articulated AFO with Hydra pneumatic damper significantly improved self selected speed, cadence, step length in participants (P<0.005). Furthermore, the peak and mean of torque, push off velocity and energy storing/returning significantly improved by articulated AFO with Hydra pneumatic damper (P<0.005). 

The newly designed articulated AFO with Hydra pneumatic damper, as an actuator, provided adequate torque in drop foot patient. Kinetic, spatio-temporal and kinematic parameters improved by wearing this AFO at comfortable self-selected speed.

Drop foot syndrome is a disorder characterized by foot slapping after the initial contact and foot-dragging during the swing phase. Passive and hybrid passive ankle foot orthoses (AFOs) are often prescribed in these patients; however, the effects of these AFO designs on kinematic parameters during gait are unclear. The aim of this study was to compare the effect of innovative designed storing-restoring hybrid passive AFOs versus posterior leaf spring AFO on ankle joint kinematics in drop foot patients

The present study was a case series where a single case and 3 cases with drop foot syndrome were recruited. This study was designed in 2 phases: the baseline phase with their PLS AFOs and an intervention phase in which innovative designed AFO were assessed. Each phase included 5 measurement sessions which were performed in 5 consecutive weeks. The celeration line method was used to detect the significant differences between the phases.

The results of this study showed a significant increase in the kinematic angles parameters at the initial contact, the loading response, the mid stance, terminal stance, pre swing, initial swing, mid swing, and terminal swing with the innovative designed AFO than with PLS AFO (p<0.05).

The results of the present study suggested that use of the innovative designed AFO may have a positive effect on ankle joint kinematics parameters in people with drop foot.
