ISB recommendation on definitions of joint coordinate systems of various joints for the reporting of human joint motion-Part II: shoulder, elbow, wrist and hand

Fiber-based structures are highly desirable for wearable electronics that are expected to be light-weight, long-lasting, flexible, and conformable Many fibrous structures have been manufactured by well-established lost-effective textile processing technologies, normally at ambient conditions The advancement of nanotechnology has made it feasible to build electronic devices directly on the surface or inside of single fibers, which have typical thickness of several to tens microns However, imparting electronic functions to porous, highly deformable and three-dimensional fiber assemblies and maintaining them during wear represent great challenges from both views of fundamental understanding and practical implementation This article attempts to critically review the current state-of-arts with respect to materials, fabrication techniques, and structural design of devices as well as applications of the fiber-based wearable electronic products In addition, this review elaborates the performance requirements of the fiber-based wearable electronic products, especially regarding the correlation among materials, fiber/textile structures and electronic as well as mechanical functionalities of fiber-based electronic devices Finally, discussions will be presented regarding to limitations of current materials, fabrication techniques, devices concerning manufacturability and performance as well as scientific understanding that must be improved prior to their wide adoption

Quantification of physical activities in daily life in patients with chronic obstructive pulmonary disease has increasing clinical interest.However,detailedcomparisonwithhealthysubjectsisnotavailable.Furthermore,itisunknownwhethertimespentactivelyduring daily life is related to lung function, muscle force, or maximal and functional exercise capacity. We assessed physical activities and movement intensity with the DynaPort activity monitor in 50 patients (age 64 7 years; FEV1 43 18% predicted) and 25 healthy elderly individuals (age 66 5 years). Patients showed lower walking time (44 26 vs. 81 26 minutes/day), standing time (191 99 vs. 295 109 minutes/day), and movement intensity during walking (1.8 0.3 vs. 2.4 0.5 m/second 2 ;p 0.0001 for all), as well as higher sitting time (374 139 vs. 306 108 minutes/day; p 0.04) and lying time (87 97 vs. 29 33 minutes/day; p 0.004). Walking time was highly correlated with the 6-minute walking test (r 0.76, p 0.0001) and more modestly to maximal exercise capacity, lung function, and muscle force (0.28 r 0.64, p 0.05). Patients with chronic obstructive pulmonary disease are

BackgroundStress fractures are common overuse injuries in runners and appear most frequently in the metatarsals.PurposeTo investigate fatigue-related changes in surface electromyographic activity patterns and plantar pressure patterns during treadmill running as potential causative factors for metatarsal stress fractures.Study DesignProspective cohort study with repeated measurements.MethodsThirty experienced runners volunteered to participate in a maximally exhaustive run above the anaerobic threshold. Surface electromyographic activity was monitored for 14 muscles, and plantar pressures were measured using an in-shoe monitoring system. Fatigue was documented with blood lactate measurements.ResultsThe results demonstrated an increased maximal force (5%, P < .01), peak pressure (12%, P < .001), and impulse (9%, P < .01) under the second and third metatarsal head and under the medial midfoot (force = 7%, P < .05; pressure = 6%, P < .05; impulse = 17%, P < .01) toward the end of the fatiguing run.

The influence of muscle fatigue on electromyogram and plantar pressure patterns as an explanation for the incidence of metatarsal stress fractures

BackgroundPrevious studies have shown that eccentric training has a positive effect on chronic Achilles tendinopathy. A new strategy for the treatment of chronic Achilles tendinopathy is the AirHeel brace.HypothesisAirHeel brace treatment improves the clinical outcome of patients with chronic Achilles tendinopathy. The combination of the AirHeel brace and an eccentric training program has a synergistic effect.Study DesignRandomized controlled clinical trial; Level of evidence, 1.MethodsOne hundred patients were randomly assigned to 1 of 3 treatment groups: (1) eccentric training, (2) AirHeel brace, and (3) combination of eccentric training and AirHeel brace. Patients were evaluated at 6, 12, and 54 weeks after the beginning of the treatment protocol with ultrasonography, visual analog scale (VAS) for pain, American Orthopaedic Foot and Ankle Society (AOFAS) ankle score, and Short Form-36 (SF-36).ResultsThe VAS score for pain, AOFAS score, and SF-36 improved significantly in all 3 groups at all 3 follow-up...
