Validation of temporal gait metrics from three IMU locations to the gold standard force plate.

The purpose of this work is to compare temporal gait parameters from three different IMU locations to the gold standard force platform. 33 subjects (12 F, 21 M) performed twenty gait trials each while wearing inertial measurement units (IMUs) on the trunk, both shanks and both feet. Data was simultaneously collected from a laboratory embedded force plate.

Validation and comparison of shank and lumbar-worn IMUs for step time estimation.

Gait assessment is frequently used as an outcome measure to determine changes in an individual's mobility and disease processes. Inertial measurement units (IMUs) are quickly becoming commonplace in gait analysis. The purpose of this study was to determine and compare the validity of shank and lumbar IMU mounting locations in the estimation of temporal gait features.

Fluoroscopically guided transurethral removal and/or replacement of ureteric stents in women.

Background: Traditionally double J ureteric stents have been removed and replaced via cystoscopy. Fluoroscopically guided procedures for the removal/replacement of stents using endovascular snare devices have previously been described as a successful alternative.

Purpose: To evaluate the technical and clinical success of fluoroscopically guided transurethral removal and/or replacement of ureteric stents in women.

Objective diagnosis of ADHD using IMUs.

This work proposes the use of miniature wireless inertial sensors as an objective tool for the diagnosis of ADHD. The sensors, consisting of both accelerometers and gyroscopes to measure linear and rotational movement, respectively, are used to characterize the motion of subjects in the setting of a psychiatric consultancy. A support vector machine is used to classify a group of subjects as either ADHD or non-ADHD and a classification accuracy of greater than 95% has been achieved.

Combined thrombin-collagen injection for the management of an iatrogenic pseudoanuerysm in the popliteal region.

Pseudoaneurysm formation is a rare but recognized complication of total knee arthroplasty (TKR), with fewer than 20 cases described in the literature. Multiple management techniques have been described for such pseudoaneurysms. As thrombin injection is an established technique, we report a case of a post-TKR tibioperoneal pseudoaneurysm successfully occluded via percutaneous injection of a dual thrombin-collagen preparation.
