Processes of capturing solid geometry features as threedimensional data for analysis, simulation, or reverse engineering require the use of laser-based reverse engineering hardware, commonly known as digitizers. The most common digitizers used within manufacturing contexts are articulated arm-based coordinate measuring machines, which have been augmented with a laser-head probe. Typical usage t...

Neurons in monkey primary motor cortex (M1) tend to be most active for certain directions of hand movement and joint-torque loads applied to the limb. The origin and function of these biases in preference distribution are unclear but may be key to understanding the causal role of M1 in limb control. We demonstrate that these distributions arise naturally in a network model that commands muscle ...

Despite the critical role tendons play in transmitting loads throughout the musculoskeletal system, little is known about the microstructural mechanisms underlying their mechanical function. Of particular interest is whether collagen fibrils in tendon fascicles bear load independently or if load is transferred between fibrils through interfibrillar shear forces. We conducted multiscale experime...

Load Carriage using backpacks is an occupational task and can be a recreational pursuit. The aim of this study was to investigate the mechanisms responsible for changes in neuromuscular function of the m. quadriceps femoris following load carriage. The physiological responses of 10 male participants to voluntary and electrically stimulated isometric contractions were measured before and immedia...

The awkward movements and postures associated with childcare activities can lead to musculoskeletal symptoms in the neck and shoulders. "Dakko" is a method for carrying a child in Japan, and recently it has been reported to cause shoulder stiffness. To our knowledge, the relationship between childcare activities and the physical load on the neck and shoulders is poorly understood. The present s...

In this study, the accuracy of the inputs required for finite element analysis, which is mainly used for the biomechanical analysis of bones, was improved. To ensure a muscle force and joint contact force similar to the actual values, a musculoskeletal model that was based on the actual gait experiment was used. Gait data were obtained from a healthy male adult aged 29 who had no history of mus...

The introduction of Industrial Revolution 4.0 and the current pandemic has increased demand for food delivery services. However, riding motorcycles may pose risk experiencing musculoskeletal disorders. This study aimed to assess prevalence back pain among riders. A cross-sectional was conducted 39 riders in Kota Bharu. modified adapted questionnaire from Nordic Musculoskeletal Questionnaire use...
