Accurate and Reliable Gait Cycle Detection in Parkinson's Disease.

There is a growing interest in the use of Inertial Measurement Unit (IMU)-based systems that employ gyroscopes for gait analysis. We describe an improved IMU-based gait analysis processing method that uses gyroscope angular rate reversal to identify the start of each gait cycle during walking. In validation tests with six subjects with Parkinson disease (PD), including those with severe shuffling gait patterns, and seven controls, the probability of True-Positive event detection and False-Positive event detection was 100% and 0%, respectively.

Clinical evaluation of a combined regenerative technique with enamel matrix derivative, bone grafts, and guided tissue regeneration.

The goal of this study was to evaluate the clinical changes obtained when intra-bony defects were treated with an enamel matrix derivative (EMD), a bone graft, and guided tissue regeneration. Fifty patients with a periodontal defect not associated with a furcation and with an attachment loss of at least 7.0 mm were included in this study.

A comparison of three techniques to obtain root coverage on mandibular incisors.

Background: Multiple variations on the subepithelial connective tissue graft have been shown to produce good clinical results. The goal of this study was to compare three variations in the treatment of recession on mandibular incisors.

Methods: An a priori analysis was done to determine the sample size.
