BACKGROUND AND AIM: Various measurement devices are available for detection of halitosis. For epidemiologic studies, it is necessary to use a portable and small device. This study aimed to investigation of correlation between measuring the device (Etiquette checker) with Halimeter. METHODS: One hundred volunteers (students and patients) participated in this study. The amount of volatile sulfur ...

This paper presents a biometric user authentication based on a person’s gait. Unlike most previous gait recognition approaches, which are based on machine vision techniques, in our approach gait patterns are extracted from a physical device attached to the lower leg. From the output of the device accelerations in three directions: vertical, forward-backward, and sideways motion of the lower leg...

Shuffling and freezing while walking can impair function in patients with Parkinson disease (PD). Open-loop devices that provide fixed-velocity visual or auditory cues can improve gait but may be unreliable or exacerbate freezing of gait in some patients. We examined the efficacy of a closed-loop, accelerometer-driven, wearable, visual-auditory cueing device in 13 patients with PD with off-stat...

BACKGROUND Previous studies have shown the effect of a unique therapy with a non-invasive biomechanical foot-worn device (AposTherapy) on Caucasian western population suffering from knee osteoarthritis. The purpose of the current study was to evaluate the effect of this therapy on the level of symptoms and gait patterns in a multi-ethnic Singaporean population suffering from knee osteoarthritis...

OBJECTIVE To compare the effect of a surface peroneal nerve stimulator (PNS) versus an ankle-foot orthosis (AFO) on spatiotemporal and kinematic parameters of gait in patients with multiple sclerosis. DESIGN This was a case series design. PARTICIPANTS Four subjects with multiple sclerosis and dorsiflexion weakness. INTERVENTION Quantitative gait analysis with the use of (1) no device, (2)...

Human Silhouette Extraction is one of the vital task in human abnormality gait detection. Hence in this study, extraction of human gait silhouette using Haar Cascade classifier is developed. This is done by detecting the region of interests (ROI) and by cropping the selected areas followed by background subtraction to eliminate unwanted background and further convert the images to silhouettes f...

A novel device for monitoring gait, which can be used in confined spaces, is described. In addition to distance/time assessment of gait, it measures foot separation whilst walking. A field trial illustrates its potential in the investigation of falls.

BACKGROUND Orthotic devices are used to help children progressively acquire a more physiologic walking pattern. METHODS To determine the effect of an orthotic device with an out-toeing wedge along with a physiologic shoe as treatment for in-toed gait, angle of gait was measured in 48 children aged 3 to 14 years with in-toed gait. The following comparisons were made: angle of gait in children ...

To examine the range of gait acceleration and cycle in daily walking of patients with Parkinson's disease (PD), we compared the gait of 40 patients with PD and 17 normal controls by using a newly developed long-term monitoring device that extracts gait-related accelerations from overall movements-related accelerations. The range of change in gait acceleration, relative to the control, was less ...

The problem of joint classification gait and device mode from inertial measurement units (IMU) measurements is considered. For this, an approach for computing unique signature using collected body-worn (IMUs) proposed.The represents one full cycle the human gait, suitable off-line or on-line mode. can also be used to jointly classify identifies how IMU-equipped being carried by user. method bas...
