Reducing or preventing injuries; Reducing workers’ efforts by decreasing forces in lifting, handling, pushing, and pulling materials; Reducing risk factors for musculoskeletal disorders (e.g., awkward postures from reaching into containers) Increasing productivity, product and service quality, and worker morale
This lifting and holding can strain the lower back, shoulders, neck, arms, hands, and wrists. [16] Many tools used today are mechanical, but some tasks still need to be done manually. [ 16 ] Using a power vacuum to lift large, lighter items (such as a pane of glass) can remove the need to lift items manually and can take most, if not all, of ...
The DASS (Depression Anxiety Stress Scales) contains a scale for stress based on self-report items. Changes in blood pressure and galvanic skin response can also be measured to test stress levels. A digital thermometer can be used to evaluate changes in skin temperature, which can indicate activation of the fight-or-flight response drawing ...
Strains can include mental and physical health problems. Misfit can also lead to lower productivity and other work problems. [ 9 ] The P–E fit model was popular in the 1970s and the early 1980s; however, since the late 1980s interest in the model has waned because of difficulties representing P–E discrepancies mathematically and statistical ...
Occupational stress, anxiety, and depression can be directly correlated to psychosocial hazards in the workplace. [ 13 ] Exposure to workplace psychosocial hazards has been strongly correlated with a wide spectrum of unhealthy behaviors such as physical inactivity, excessive alcohol and drug consumption, nutritional imbalance and sleep ...
Suggestions for preventing various back injuries primarily address the causes of those injuries. The risk for back sprains and strains may be reduced with lifestyle choices, including smoking cessation, limiting alcohol, maintaining a healthy weight, and keeping bones and muscles strong with adequate exercise and a healthy diet.

Sprains may be mild (first degree), moderate (second degree), or severe (third degree), with the latter two classes involving some degree of tearing of the ligament. Sprains can occur at any joint but most commonly occur in the ankle, knee, or wrist. [2] An equivalent injury to a muscle or tendon is known as a strain.
Mild sprains (Grades 1-2) relating to over stretching or partial tears typically begin to feel better in a few days to a week and heal by six weeks. More severe ankle sprains (Grades 2-3) involving a full tear or rupture could take more than a few weeks or months to fully recover. [39] The mean time patients return to sports is 12.9 weeks.
