– Contributing factors• Type of grip• Weight of object• Body posture• Type and duration of

the task

RISK FACTOR IN ERGONOMICSRepetitive Motion

(kerja berulang kali)

– Stress on muscles and tendons

– Contributing factors• Duration and speed of

repetitious movement• Number of muscles

involved• Required force

– Raising and lowering the arm over and over again

RISK FACTOR IN ERGONOMICSAwkward or Static Postures

Lifting while twisting, reaching, or turning

MUSCULOSKELETAL DISORDERS (MSDs)

1. Carpal tunnel syndrome (CTS) Carpal tunnel syndrome (CTS), or median neuropathy at the wrist, is a medical condition in which the median nerve is compressed at the wrist, leading to paresthesias, numbness and muscle weakness in the hand. This is due to repetitive and forceful movements

MUSCULOSKELETAL DISORDERS (MSDs)

2. Whole Body vibration Whole Body exposure

to vibration results from vehicles such as forklifts, cranes, trucks, buses subways and aircraft.

High or prolonged exposure to whole body vibration can affect the skeletal muscles and cause low- back pain

MUSCULOSKELETAL DISORDERS (MSDs)

3. vibration syndrome (HAVS) The hand-arm vibration syndrome (HAVS) also named as 'white finger'. It may also cause permanent numbness of fingers. It is caused by working with vibrating tools, usually over a number of years. If you stop working with vibrating tools it may prevent mild symptoms from getting worse
