Abstract

A ergonomic handle that can be added to existing haptic devices, composed by a spherical mechanism providing hand orientation and a grasping mechanism is shown. Both the proposed spherical mechanism and the handle have been ergonomically designed to avoid postures that could lead to physical discomfort or cumulative traumas such as carpal tunnel syndrome or tenosynovitis.

Ergonomic hazard

Ergonomic hazards are physical conditions that may pose a risk of injury to the musculoskeletal system due to poor ergonomics. These hazards include awkward or static postures, high forces, repetitive motion, or short intervals between activities. The risk of injury is often magnified when multiple factors are present. Environmental, operational, or design factors can all negatively impact a worker or user; examples include whole-body or hand/arm vibration, poor lighting, or poorly designed tools, equipment, or workstations.

Human factors and ergonomics

Human factors and ergonomics (commonly referred to as human factors engineering or HFE) is the application of psychological and physiological principles to the engineering and design of products, processes, and systems. Primary goals of human factors engineering are to reduce human error, increase productivity and system availability, and enhance safety, health and comfort with a specific focus on the interaction between the human and equipment.

Carpal tunnel syndrome

Carpal tunnel syndrome (CTS) is the collection of symptoms and signs associated with median neuropathy at the carpal tunnel. Most CTS is related to idiopathic compression of the median nerve as it travels through the wrist at the carpal tunnel (IMNCT). Idiopathic means that there is no other disease process contributing to pressure on the nerve. As with most structural issues, it occurs in both hands, and the strongest risk factor is genetics. Other conditions can cause CTS such as wrist fracture or rheumatoid arthritis.
