Direct continuous electromyographic control of a powered prosthetic ankle for improved postural control after guided physical training: A case study.

Despite the promise of powered lower limb prostheses, existing controllers do not assist many daily activities that require continuous control of prosthetic joints according to human states and environments. The objective of this case study was to investigate the feasibility of direct, continuous electromyographic (dEMG) control of a powered ankle prosthesis, combined with physical therapist-guided training, for improved standing postural control in an individual with transtibial amputation. Specifically, EMG signals of the residual antagonistic muscles (i.

The ability of MRI to predict failure of nonoperative treatment of pyogenic vertebral osteomyelitis.

Pyogenic vertebral osteomyelitis (PVO) can be treated most often by medical management. For those failing with medical management, surgical delay can result in increased morbidity. Therefore, the ability to predict failure of medical management on presentation would greatly improve the outcome.

Accessory tragus: A report of 2 cases.

The purpose of this article was to review the embryology of the external ear, as related to the clinical finding of accessory tragus (ear tags). Medical management of the accessory tragus is discussed, as well as differential diagnoses and associated syndromes. A general clinical description of accessory tragus is described, and 2 specific cases in pediatric patients are presented.
