Information of hotel cleaners’ musculoskeletal pain can be acquired by subjective survey on patients. The ultrasonic waves and X-ray examination can reveal the parts of muscular trauma, bones and joints, and fracture. Medical instruments can recognize the situation musculoskeletal pain and related treatment and recovery will be offered. However, after pain is relieved, hotel cleaners often expe...

This work presents a system that permits a real-time ergonomic assessment of manual tasks in an industrial environment. First, a biomechanical model of the upper body has been developed by using inertial sensors placed at different locations on the upper body. Based on this model, a computerized RULA ergonomic assessment was implemented to permit a global risk assessment of musculoskeletal diso...

The Rapid Upper Limb Assessment (RULA) survey is a posture-sampling tool used specifically to examine the level of risk associated with upper limb disorders of individual workers. This paper examines the relationship between RULA's postural scoring system and measures of surface electromyography (EMG), self-reports of discomfort, and job attitude questionnaires. Twenty participants each perform...

Evaluation of potential risks of musculoskeletal disorders in real workstations is challenging as the environment is cluttered, which makes it difficult to correctly assess the pose of a worker. Being marker-free and calibration-free, Microsoft Kinect is a promising device to assess these poses, but it can deliver unreliable poses especially when occlusions occur. To overcome this problem, we p...

New technologies and changes in dental care aimed to give the dentist better comfort and better health condition, among them Proprioceptive derivation (Pd) concept was introduce in Thailand. The aim of this study was to investigate the differences in dentist’s working posture when adopting different work concepts: Pd and Conventional concept. The result show differences in dentists’ sitting pos...

We hypothesized that a laparoscopic technique for Roux-en-Y gastric bypass surgery is associated with more musculoskeletal discomfort and ergonomic strain than a robotic technique. This pilot project studied one surgeon while he performed four laparoscopic and four robotic (da Vinci system) Roux-en-Y gastric bypass procedures. We measured musculoskeletal discomfort with body part discomfort sco...
