Repeating motions and actions whilst performing an activity increases an individual's risk of accumulating acute musculoskeletal injuries. Factors that affect sustaining these injuries include; duration of activity, the force required to complete the activity, the environment of the workplace and work postures.
MSD risk factors involve doing tasks with heavy force, repetition, or maintaining a nonneutral posture. [8] Of particular concern is the combination of heavy load with repetition. [8] Although poor posture is often blamed for lower back pain, a systematic review of the literature failed to find a consistent connection. [9]
The NIAMS is committed to pursuing new opportunities in genetics and genomics research, clinical trial design, pain, and biopsychosocial aspects of diseases in this portfolio. It is also committed to identification of risk factors for these disorders, enhancement of disease prediction, and advancement of prevention strategies.
Joint pain, stiffness, redness, swelling, decreased range of motion [2] [3] Complications: Amplified musculoskeletal pain syndrome [4] Types > 100, most common (osteoarthritis, rheumatoid arthritis) [5] [6] [7] Risk factors: Family history, age, sex trait, previous joint injury, obesity.

Explanatory model of chronic pain. Chronic pain is defined as reoccurring or persistent pain lasting more than 3 months. [1] The International Association for the Study of Pain (IASP) defines pain as "An unpleasant sensory and emotional experience associated with, or resembling that associated with, actual or potential tissue damage". [2]
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 insufficient rest breaks activities. The risk of injury is often magnified when multiple factors are present.
Women are more at risk for stress fractures than men due to factors such as lower aerobic capacity, reduced muscle mass, lower bone mineral density, among other anatomical and hormone-related elements. Women also have a two- to four-times increased risk of stress fractures when they have amenorrhea compared to women who are eumenorrheic. [18]
A repetitive strain injury (RSI) is an injury to part of the musculoskeletal or nervous system caused by repetitive use, vibrations, compression or long periods in a fixed position. [1] Other common names include repetitive stress injury , repetitive stress disorders , cumulative trauma disorders ( CTDs ), and overuse syndrome .
