Manipulating device-to-body forces in passive exosuit: An experimental investigation on the effect of moment arm orientation using passive back-assist exosuit emulator.

Passive exosuits have been vastly researched in the past decade for lifting tasks to alleviate the mechanical loading on the spine and reduce the lower back muscle activities in lifting tasks. Despite promising advantages of exosuits, factors such as comfort directly influence the user's acceptability of such body-worn devices. Exosuits' routing/anchoring points, which transmit device-to-body forces, remain the leading cause of discomfort among users.

Learning complex upper-limb movements through practicing movement elements.

Upper-limb complex movements constitute a major part of our daily activities. Research shows complex movements are generated by sequences of movement elements represented by a unimodal bell-shaped velocity curve. We utilized this understanding in the field of motor skill acquisition and hypothesized that practicing a movement element of a complex movement trajectory will facilitate the performance on the respective complex movement trajectory.

Vibratory cue training elicits anticipatory postural responses to an external perturbation.

Anticipatory postural adjustments (APAs) represent the feedforward mechanism of neuromuscular control essential for maintaining balance under predictable perturbations. The importance of vision as a distal sensory modality in the generation of APAs is well established. However, the capabilities of external cues in generating APAs are less explored.

Lower limb rehabilitation robotics: The current understanding and technology.

Background: With the increasing rate of ambulatory disabilities and rise in the elderly population, advance methods to deliver the rehabilitation and assistive services to patients have become important. Lower limb robotic therapeutic and assistive aids have been found to improve the rehabilitation outcome.

Objective: The article aims to present the updated understanding in the field of lower limb rehabilitation robotics and identify future research avenues.

Finite Element Analysis (FEA) of Perpendicular Plating Versus Conventional Plating in Mandibular Symphysis Fracture.

Aim And Objective: To perform the comparative finite element analysis of conventional and perpendicular plating in mandibular symphyseal fracture.

Material And Method: Two FE model of mandible were developed and symphyseal fracture was created in both of them. Each fractured model was fixed by conventional method 2.

Lower limb rehabilitation using multimodal measurement of sit-to-stand and stand-to-sit task.

Purpose: Assistive and rehabilitation devices are dependent upon detecting the user intent through physiological and kinematics changes. Rising from a chair and vice-versa have been less investigated for the purpose of rehabilitation-aids. This study investigates the muscle activation along with trunk and knee biomechanics in sagittal plane during sit-to-stand and stand-to-sit transfer.

Ergonomics investigation for orientation of the handles of wood routers.

Objectives: Improperly designed hand tools not only expose workers to potential health risks but also hamper their productivity. This study tries to improve the ergonomics of wood routing tasks, suggesting better handle orientations for hand-held wood routers.

Methods: Seven different handle combinations were tested over two routing tasks (beading and dado) with regard to perceived discomfort, electromyography (EMG) of biceps brachii and extensor carpi radialis brevis and hand-arm vibrations (HAV).

Role of 1.5 mm microplates in treatment of symphyseal fracture of mandible: A stress analysis based comparative study.

Aims And Objectives: To perform comparative finite element analysis (FEA)for 2.0 mm standard miniplate and 1.5 mm microplate in isolated symphyseal mandibular fractures.

Evaluation of Wound Morphology of Sclerotomy Sites of Sutureless Vitrectomy Using Spectralis Anterior Segment Optical Coherence Tomography.

Purpose: The aim of the study was to evaluate wound morphology in vivo in eyes undergoing sutureless vitrectomy.

Design: This was a prospective consecutive case series.

Methods: Twenty eyes undergoing sutureless vitrectomy were evaluated using anterior segment optical coherence tomography on days 1, 15, and 30.

Wavelength scaling of high harmonic generation close to the multiphoton ionization regime.

We study the wavelength scaling of high harmonic generation efficiency with visible driver wavelengths in the transition between the tunneling and the multiphoton ionization regimes where the Keldysh parameter is around unity. Our experiment shows a less dramatic wavelength scaling of efficiency than the conventional case for near- and mid-IR driver wavelengths, and it is well explained by a generalized three-step model for increased Keldysh parameters that employs complex ionization times in addition to the nonadiabatic ionization. The complex ionization time is critical to avoid the divergence when replacing the quasistatic ionization model by the more general nonadiabatic ionization model.
