Time to Navigate: A Practical Objective Clinical Measure for Freezing of Gait Severity in People With Parkinson Disease.

Objectives: To provide an easy-to-use measure, as existing objective assessments for freezing of gait (FOG) severity may be unwieldy for routine clinical practice, this study explored time taken to complete the recently validated FOG severity tool and its components.

Design: A cross-sectional study.

Setting: Outpatient clinics of a tertiary hospital.

Validity and reliability of a new clinician-rated tool for freezing of gait severity.

Purpose: The Freezing of Gait Severity Tool (FOG Tool) was developed because of limitations in existing assessments. This cross-sectional study investigated its validity and reliability.

Methods: People with Parkinson's disease (PD) were recruited consecutively from clinics.

Detection of Freezing of Gait Using Convolutional Neural Networks and Data From Lower Limb Motion Sensors.

Parkinson's disease (PD) is a chronic, non-reversible neurodegenerative disorder, and freezing of gait (FOG) is one of the most disabling symptoms in PD as it is often the leading cause of falls and injuries that drastically reduces patients' quality of life. In order to monitor continuously and objectively PD patients who suffer from FOG and enable the possibility of on-demand cueing assistance, a sensor-based FOG detection solution can help clinicians manage the disease and help patients overcome freezing episodes. Many recent studies have leveraged deep learning models to detect FOG using signals extracted from inertial measurement unit (IMU) devices.

Convolutional Neural Network for Freezing of Gait Detection Leveraging the Continuous Wavelet Transform on Lower Extremities Wearable Sensors Data.

Freezing of Gait is the most disabling gait disturbance in Parkinson's disease. For the past decade, there has been a growing interest in applying machine learning and deep learning models to wearable sensor data to detect Freezing of Gait episodes. In our study, we recruited sixty-seven Parkinson's disease patients who have been suffering from Freezing of Gait, and conducted two clinical assessments while the patients wore two wireless Inertial Measurement Units on their ankles.

A Wearable, Patient-Adaptive Freezing of Gait Detection System for Biofeedback Cueing in Parkinson's Disease.

Freezing of Gait (FoG) is a common motor-related impairment among Parkinson's disease patients, which substantially reduces their quality of life and puts them at risk of falls. These patients benefit from wearable FoG detection systems that provide timely biofeedback cues and hence help them regain control over their gait. Unfortunately, the systems proposed thus far are bulky and obtrusive when worn.

Regression analysis of gait parameters and mobility measures in a healthy cohort for subject-specific normative values.

Background: Deviation in gait performance from normative data of healthy cohorts is used to quantify gait ability. However, normative data is influenced by anthropometry and such differences among subjects impede accurate assessment. De-correlation of anthropometry from gait parameters and mobility measures is therefore desirable.

A systematic review of the diagnostic utility of simple tests of change after trial removal of cerebrospinal fluid in adults with normal pressure hydrocephalus.

Objective: To synthesize the evidence regarding the diagnostic value of simple ancillary tests post cerebrospinal fluid drainage in normal pressure hydrocephalus.

Data Sources: MEDLINE, CINAHL, PsycINFO, Scopus, Web of Science, and Cochrane library databases; last searched on 12 September 2017.

Review Methods: This review was performed applying the steps of the PRISMA statement.

The effects of toe spreader in people with overactive toe flexors post stroke: a randomized controlled pilot study.

Objectives: To investigate the long-term effects of the toe spreader on gait characteristics, pain, activity level and balance in individuals with chronic stroke who exhibited tonic toe flexion reflex. The secondary objectives were to determine the sample size for future studies and to assess compliance to the use of the toe spreader.

Design: Single-blind, randomized controlled pilot trial.
