DescriptionWhile the effects of physical risk factors on MSD development have been a primary focus of musculoskeletal research, it is clear that psychological stressors and certain personal characteristics (e.g., aging, sex, and obesity) are associated with increased MSD risk. The psychological and personal characteristics listed above share a common characteristic: all are associated with disruption of the body’s neuroendocrine and immune responses resulting in an impaired healing process. An impaired healing response may result in reduced fatigue life of musculoskeletal tissues due to a diminished ability to keep pace with accumulating damage (perhaps reparable under normal circumstances), and an increased vulnerability of damaged tissue to further trauma owing to the prolonged healing process. Research in engineered self-healing materials suggests that decreased healing kinetics in the presence of mechanical loading can substantially reduce the fatigue life of materials. A model of factors influencing damage accrual and healing will be presented.
