An ankle exosuit tuned to the measured muscle dynamics of user during multiple walking tasks improves energy economy.

The human body constantly experiences mechanical loading. However, quantifying internal loads within the musculoskeletal system remains challenging, especially during unconstrained dynamic activities. Conventional measures are constrained to laboratory settings, and existing wearable approaches lack muscle specificity or validation movement. Here, we present a strategy for estimating corresponding joint torque from muscles with different architectures various activities using A-mode...

The MIT-Skywalker is a novel robotic device developed for the rehabilitation or habilitation of gait and balance after neurological injury. It represents an embodiment concept exhibited by passive walkers training. Its novelty extends beyond walker quintessence to unparalleled versatility among lower extremity devices. For example, it affords potential implement training approach built upon our working model movement primitives based on submovements, oscillations, mechanical impedances. This...

Exosuits have the potential to assist locomotion in both healthy and pathological populations, but effect of exosuit assistance on underlying muscle-tendon tissue loading is not yet understood. In this study, we used shear wave tensiometers characterize modulation Achilles tendon force with load carriage at ankle. When walking (1.25 m/s) unassisted a treadmill weights 15 30% body weight, peak increased by 11 23%, respectively. Ankle significantly reduced relative unassisted, although...

Within the human population, there is large interindividual variability in timing of sleep and circadian rhythms. This has been attributed to individual differences physiology, and/or light exposure. Recent experimental evidence suggests that latter necessary evoke timing. We used a validated model physiology test hypothesis intrinsic are amplified by self-selected use artificial sources. tested under 2 conditions motivated an study (Wright et al., 2013): (1) “natural” cycle, (2) “realistic”...

Evidences suggest that the presence of chronic kidney disease (CKD) is associated with cerebrovascular diseases related cognitive decline in dialysis patients. As mitochondrial dysfunction implicated neurodegenerative disorders, we hypothesized changes brain mitochondria occur due to vascular calcification induced by renal failure and opening potassium channel using nicorandil may prevent its dysfunction. Brain tissues from rats were studied. Nicorandil (7.5 mg/kg b.wt.) was given either...

Abstract Background Individualized, targeted, and intense training is the hallmark of successful gait rehabilitation in people post-stroke. Specifically, increasing use impaired ankle to increase propulsion during stance phase has been linked higher walking speeds symmetry. Conventional progressive resistance one method used for individualized rehabilitation, but often fails target paretic plantarflexion walking. Wearable assistive robots have successfully assisted ankle-specific mechanisms...

Over the years, there has been a slow but steady change in attitude of society towards different kinds sexuality. However, on social media platforms, where people have license to be anonymous, toxic comments targeted at homosexuals, transgenders and LGBTQ+ community are not uncommon. Detection homophobic can useful making internet safer place for everyone. For this task, we used combination word embeddings SVM Classifiers as well some BERT-based transformers. We achieved weighted F1-score...

Ankle-targeting resistance training for improving plantarflexion function during walking increases rehabilitation intensity, an important factor motor recovery after stroke. However, understanding of the effects resisting stance on joint kinetics and muscle activity-key outcomes in evaluating its potential value rehabilitation-remains limited. This initial study uses a unilateral exosuit that resists mid-late unimpaired individuals to test hypotheses when is resisted, would (1) increase...

Exosuits can reduce metabolic demand and improve gait. Controllers explicitly derived from biological mechanisms that reflect the user's joint or muscle dynamics should in theory allow for individualized assistance enable adaptation to changing With goal of developing an exosuit control strategy based on power, we present approach estimating, at real time rates, when soleus begins generate positive power. A low-profile ultrasound system recorded B-mode images walking individuals. An...

A quantitative analysis of human gait patterns in space–time provides an opportunity to observe variability within and across individuals varying motor capabilities. Impaired significantly affects independence quality life, thus a large part clinical research is dedicated improving through rehabilitative therapies. Evaluation these paradigms relies on understanding the characteristic differences kinematics underlying biomechanics impaired unimpaired locomotion, which has motivated...

This paper aims to present the results of a survey conducted determine use online public accesscatalogue (OPAC) at library Anna University Regional Campus, Coimbatore. The questionnairebased library. 190 samples questionnaire is distributed randomly between thestaff and students Coimbatore, out which 154 completed validquestionnaires (81.00%) are received for analysis. data from respondents through thequestionnaires analyzed. result study reveals that significant number users...

This paper describes the results of a month-long case study stroke patient training with anklebot conducted at MIT Newman Laboratory for Biomechanics. The provides promising evidence reducing paretic impairment using in patients. We found statistically significant increase soleus and tibialis anterior EMG levels following training.

Abusive language has lately been prevalent in comments on various social media platforms. The increasing hostility observed the internet calls for creation of a system that can identify and flag such acerbic content, to prevent conflict mental distress. This task becomes more challenging when low-resource languages like Tamil, as well often-observed Tamil-English code-mixed text, are involved. approach used this paper classification model includes different methods feature extraction use...

Road commuting often bears unnoticed risks, contributing significantly to fatalities and injuries across the world. Alarmingly, India tops list of harm caused by road accidents with 1.5 million annual fatalities. In this scenario, real-time speed estimation, facilitated vehicle-mounted cameras, can potentially be an excellent tool for averting enhancing traffic management. This paper explores complexities emphasizing efficient object detection tracking vehicles on Indian roads through...

Reading is primarily an intellectual activity of learning new things, developing ideas and it provides a sense completeness. The reading has always been seen as important element in person’s culture education. In this paper discussed about the newspaper habits among Arts College students Madurai. A total 220 questionnaires were administered to students, 174 received response rate was 79%. From analysis discovered that majority respondents daily (66.09%) time spent less than 30 minutes are 92...

The task identifying in given text many practical applications ranging from screening public health business and management. In this paper, we propose language-agnostic model focuses on Tamil text. Our experiments yielded an F1-score 0.010.

Stroke is a leading cause of gait disability that leads to loss independence and overall quality life. The field clinical biomechanics aims study how best provide rehabilitation given an individual's impairments. However, there remains disconnect between assessment tools used in biomechanical analysis clinics. In particular, 3-dimensional ground reaction forces (3D GRFs) are quantify key characteristics, but require lab-based equipment, such as force plates. Recent efforts have shown...
