This paper evaluates three methods for objectively measuring ROM while workers are wearing protective clothing: a universal goniometer, a Leighton Flexometer, and an electrogoniometer. Ten male subjects performed a set of nine gross body movements while semi-nude and while wearing each of nine configurations of coveralls. Coveralls varied in relative size and fabric weight, Changes in joint ang...

Human movement analysis have become fundamental for a wide range of applications, such as physical therapies, neuro-rehabilitation, sports medicine, human motor system performance assessment and occupational medicine. This paper focuses on the design, implementation and validation of an inertial sensor-based portable electrogoniometer aimed at measuring joint range of motion. The system is comp...

BACKGROUND The current investigation examined the inter- and intra-tester reliability of knee joint angle measurements using a flexible Penny and Giles Biometric electrogoniometer. The clinical utility of electrogoniometry was also addressed. METHODS The first study examined the inter- and intra-tester reliability of measurements of knee joint angles in supine, sitting and standing in 35 heal...

Sensory feedback is critical to the performance of neural prostheses that restore movement control after neurological injury. Recent advances in direct paralyzed arms present new requirements for miniaturized, low-power sensor systems. To address this challenge, we developed a fully-integrated wireless sensor-brain-machine interface (SBMI) system communicating key somatosensory signals, fingert...

purpose to examine the intra-rater reliability of knee movement data in sagital plane obtained from electrogoniometer (egm) in a basic, sport-specific task of karate. methods a total of 23 elite karate athletes (13 females and 10 males; mean age of 16.10±1.26 yrs) participated in this study. the task was defined as performing three consecutive zenkutsu-dachi in two sessions. the used egm was a ...

This paper presents the development of a bioinstrumentation system for the acquisition and pre-processing of surface electromyographic (SEMG) signals, as well as the proposal of a myoelectric controller for leg prostheses, using algorithms for feature extraction and classification of myoelectric patterns. The implemented microcontrolled bioinstrumentation system is capable of recording up to fo...

OBJECTIVES This study evaluated and validated the reliability of smartphones as measuring equipment for the dorsi-plantar flexion of ankle joint position sense (JPS) ability. METHODS The subjects were 20 healthy young students in their 20s. We confirmed the concurrent validity by comparison with existing electrogoniometer data. The reliability of the smartphone was confirmed using the test-re...
