This study investigates the biomechanical impact of a passive Arm-Support Exoskeleton (ASE) on workers in wool textile processing. Eight workers, equipped with surface electrodes for electromyography (EMG) recording, performed three industrial tasks, and without exoskeleton. All tasks were an upright stance involving repetitive upper limbs actions overhead work, each presenting different physical demands terms cycle duration, load handling percentage time shoulder flexion over 80°. The use ASE consistently lowered muscle activity anterior medial deltoid compared to free condition (reduction signal Root Mean Square (RMS) −21.6% −13.6%, respectively), while no difference was found Erector Spinae Longissimus (ESL) muscle. reported complete satisfaction effectiveness as rated Quebec User Evaluation Satisfaction Assistive Technology (QUEST), 62% subjects usability score very high (>80 System Usability Scale (SUS)). reduction flexor during performance is not correlated level ergonomic risk involved. preliminary affirms potential adoption support activities processing, emphasizing its efficacy reducing activity.

Many physically straining occupations involve lifting movements over the full-vertical range of motion, which time may lead to development musculoskeletal injuries. To address this, occupational exoskeletons can be designed provide meaningful support back and shoulders during movements. This paper introduces main functional design features OmniSuit, a novel passive exoskeleton. We present technical biomechanical considerations for expected level, as well an evaluation physiological benefit usability exoskeleton in sample 31 healthy volunteers performing demanding tasks laboratory setting. The OmniSuit significantly reduced Deltoid, Trapezius Erector Spinae muscle activity between 4.1%MVC 15.7%MVC when 2.5kg weight above shoulder level (p<0.001), corresponding reduction up 49.1% compared without A position-dependent was observed with reductions ranging 4.6%MVC 14.0%MVC leaning squatting, 41.5% measured muscular predicted torque based on model were found show similar profile those phases movement are most muscles.

AbstractBack exosuits deliver mechanical assistance to reduce the risk of back injury, however, minimising restriction is critical for adoption. We developed adaptive impedance controller minimise while maintaining by modulating based on user's movement direction and nonlinear sine curves. The objective this study was compare active assistance, delivered a exosuit via our controller, three levels from passive elastics. Fifteen participants completed five experimental blocks (4 1 no-suit) consisting maximum flexion constrained lifting task. While higher stiffness elastic reduced extensor muscle activity 13%, it restricted range motion (RoM) 13°. approach did not restrict RoM reducing 15%, when lifting. This highlights an might improve usability circumventing assistance-restriction trade-off inherent approaches.Practitioner summary: demonstrates soft that delivers with can provide reductions in overall without impacts or perception discomfort.Keywords: Low painelectromyographybiomechanicsexosuitwearable robotics AcknowledgementsWe would like thank who volunteered as well Sarah Sullivan Wyss Institute Clinical Research team.Author contributionsConceptualisation: JC, MA, CJW; Development: JC; Protocol design: DAQ, DD, LA, Data collection: MA; analysis: DAQ; Funding acquisition: Writing – original draft: JMC; review & editing: JMC, CJWDisclosure statementCJW JC are inventors at least one patent application describing components described paper have been filed U.S. Patent Office Harvard University.

Performing Salah (Islamic prayer) is a fundamental practice for all Muslims worldwide, involving physical movements such as standing, bowing, and prostrating. However, these can be challenging individuals with disabilities, who often rely on conventional chairs to support their bodies during Salah. Using presents limitations in mosques, disrupting congregation alignment hindering mobility due bulky size lack of portability. To address challenges, this study aimed design develop SolatExo, passive exoskeleton prototype tailored assist disabilities The evaluated SolatExo’s impact range motion (ROM), muscle contraction using electromyography (EMG), usability, user experience. Key findings indicated no significant reduction ROM between wearing not SolatExo. EMG analysis revealed reduced suggesting its potential alleviate muscular effort Usability assessments yielded moderate good System Scale (SUS) score 68, although feedback highlighted operational difficulties, particularly transitions postures. This underscores the importance interdisciplinary collaboration biomechanics, assistive technology design, religious studies inclusive solutions enhancing accessibility. Future research should focus refining improve usability experience, addressing comfort issues incorporating advanced ergonomics principles better serve diverse needs within Muslim community. ABSTRAK: Mendirikan solat merupakan amalan wajib bagi semua umat Islam di seluruh dunia. Solat melibatkan pergerakan fizikal seperti berdiri, rukuk, dan sujud. Pergerakan ini sukar dilakukan oleh yang mempunyai kecederaan fizikal. Mereka akan menggunakan kerusi konvensional untuk solat. Walau bagaimanapun, mencetus beberapa kelemahan ketika dalam masjid, menjejaskan lurusnya saf jemaah, menghalang mobiliti mengganggu ruang jemaah lain kerana saiznya agak besar. Untuk menangani ini, kajian bertujuan mereka bentuk membangunkan sebuah eksoskeleton pasif dicipta membantu individu mendirikan Kajian telah menilai kesan SolatExo terhadap julat pergerakan, penguncupan otot elektromiografi, kebolehgunaan, pengalaman pengguna. Penemuan utama menunjukkan tiada perbezaan ketara antara memakai tidak Analisis elektromiografi pengurangan bermakna ianya berpotensi mengurangkan usaha semasa Penilaian kebolehgunaan menghasilkan skor Skala Kebolehgunaan Sistem sederhana tinggi iaitu 68. Dari aspek maklum balas pengguna, memerlukan penambahbaikan terutamanya peralihan lancar. menekankan kepentingan kerjasama pelbagai disiplin biomekanik, reka teknologi bantuan, fiqh berimpak tinggi.
