Gait analysis plays a key role in the diagnosis of Parkinson’s Disease (PD), as patients generally exhibit abnormal gait patterns compared to healthy controls. Current and severity assessment procedures entail manual visual examinations motor tasks, speech handwriting, among numerous other tests, which can vary between clinicians based on their expertise observation tasks. Automating differentiation procedure serve useful tool early PD limits data collection solely walking gait. In this...

Biofeedback is known to improve postural control and shorten rehabilitation periods among the young elderly. A biofeedback system communicates with human central nervous through a variety of feedback modalities. Vibrotactile devices are gaining attention due their desirable characteristics simplistic manner presenting biofeedback. In this study, we investigate potential incorporating real-time artificial intelligence for wobble board training, aimed at improving ankle proprioception. The...

Diabetes is a medical condition affecting multiple organs and systems due to high blood glucose levels in the body which cause diabetic neuropathy foot ulcers. Conventionally, diabetes detected using invasive methods such as pricking finger measuring glucose. However, are not convenient can pain patients. An alternative method detect use gait analysis abnormalities be analysed patterns predict severity. To our best knowledge, no studies have investigated of acceleration for detection hybrid...

Gait events and temporal parameters are presently identified by requiring both patient healthcare professional to be present at a gait laboratory. This requirement is not feasible for the general population in developing countries, where access such laboratories limited costly. Therefore, an inexpensive monitoring device has great potential address this limitation. paper presents development of low cost wearable wireless that relies on gyroscopic data to: 1) identify events, is, heel-strike...

Abstract This paper presents a wavelet neural network (WNN) based method to reduce reliance on wearable kinematic sensors in gait analysis. Wearable hinder real-time outdoor monitoring applications due drawbacks caused by multiple sensor placements and offset errors. The proposed WNN uses vertical Ground Reaction Forces (vGRFs) measured from foot kinetic as inputs estimate ankle, knee, hip joint angles. Salient vGRF are extracted primary event intervals. These selected facilitate future...

Abstract Sit-to-walk (STW) is a crucial daily task that impacts mobility, independence, and thus quality of life. Existing repositories have limited STW data with small sample sizes (n = 10). Hence, this study presents dataset obtained via the time-up-and-go test, for 65 healthy adults across three age groups – young (19–35 years), middle (36–55 years) older (above 56 years). The contains lower body motion capture, ground reaction force, surface electromyography, inertial measurement unit...

This simulation study aimed to explore the effects of mass and distribution powered ankle-foot orthoses, on net joint moments individual muscle forces throughout lower limb. Using OpenSim inverse kinematics, dynamics, static optimization tools, gait cycles ten subjects were analyzed.

It was found when device...

Forward continuation, balance, and sit-to-stand-and-walk (STSW) are three common movement strategies during sit-to-walk (STW) executions. Literature identifies these through biomechanical parameters using gold standard laboratory equipment, which is expensive, bulky, requires significant post-processing. STW strategy becomes apparent at gait-initiation (GI) the hip/knee primary contributors in STW, therefore, this study proposes to use joint angles GI as an alternate method of...

A force-sensing platform (FSP), sensitive to changes of the postural control system was designed. The measured effects perturbations in static and dynamic conditions. This paper describes implementation an FSP using resistors as sensing elements. Real-time qualitative assessment utilized a rainbow color scale identify areas with high force concentration. Postprocessing logged data provided end-users quantitative measures control. objective this research establish feasibility test gauge human...

Abstract Oil palm harvesting is a labor-intensive activity and yet it was rarely investigated. Studies showed that complementing human motion analysis with musculoskeletal modelling simulation can provide valuable information about the dynamics of joints muscles.

Six Inertial Measurement Units (IMU) Surface...

Blood Pressure (BP) is one of the vital signs in clinical assessment patients both acute and chronic care settings. However, existing BP measurement devices are less portable or invasive do not allow continuous ambulatory monitoring.
