Hazards for musculoskeletal disorders can be minimized

Musculoskeletal disorders (MSDs) are very common, but few people know what they are until they are suffering with pain. This document contains a list of common MSDs that can occur in people prior to entering the work-force because people use computers now for fun.

MSDs are common in office workers

The U.S. Department of Labor Occupational Safety and Health Administration defines musculoskeletal disorders (MSDs) as “injuries and disorders of the soft tissues (muscles, tendons, ligaments, joints and cartilage) and nervous system.  They can affect nearly all tissues, including the nerves and tendon sheaths, and most frequently involve the arms and back.”  

Up to 85 percent of the population will suffer from musculoskeletal pain.  

Musculoskeletal disorders (MSDs) are known by many names, such as cumulative trauma disorders (CTDs).

MSDs are also called repetitive motion disorders (RMDs),  overuse syndromes,  repetitive strain injuries, and “office syndrome.”

Poor ergonomic posture can cause MSDs  

When workers sit or stand in a posture that is not ergonomically correct, they can experience musculoskeletal pain.

Because musculoskeletal pain and musculoskeletal disorders (MSDs) are a major source of suffering, health care, and utilization of compensation, there is a definite need for prevention (2).

OSHA – MSDs have a variety of names

Ergonomics:  The Study of Work, OSHA 3125, page 2, states “Occupational safety and health professionals have called these disorders a variety of names, including cumulative trauma disorders, repeated trauma, repetitive stress injuries, and occupational overexertion syndrome.”

Cumulative Trauma Disorders (CTDs) defined by PEOSH:

“Cumulative trauma disorders (CTDs) are injuries of the musculoskeletal and nervous systems that may be caused by repetitive tasks, forceful exertions, vibrations, mechanical compression (pressing against hard surfaces) or sustained or awkward positions.  Cumulative trauma disorders are also called repetitive motion disorders (RMDs), overuse syndromes, regional musculoskeletal disorders, repetitive motion injuries, or repetitive strain injuries.”

Musculoskeletal Disorders in office workers:

Carpal Tunnel Syndrome – a compression of the median nerve in the wrist that may be caused by swelling and irritation of tendons and tendon sheaths.

Tendinitis – An inflammation (swelling) or irritation of a tendon. It develops when the tendon is repeatedly tensed from overuse or unaccustomed use of the hand, wrist, arm, or shoulder.

Tenosynovitis – An inflammation (swelling) or irritation of a tendon sheath associated with extreme flexion and extension of the wrist.

Low Back Disorders – These include pulled or strained muscles, ligaments, tendons, or ruptured disks. They may be caused by cumulative effects of faulty body mechanics, poor posture, and/or improper lifting techniques.

Synovitis – An inflammation (swelling) or irritation of a synovial lining (joint lining).

DeQuervain’s Disease – A type of synovitis that involves the base of the thumb.

Bursitis – An inflammation (swelling) or irritation of the connective tissue surrounding a joint, usually of the shoulder.

Epicondylitis – Elbow pain associated with extreme rotation of the forearm and bending of the wrist. The condition is also called tennis elbow or golfer’s elbow.

Thoracic Outlet Syndrome – a compression of nerves and blood vessels between the first rib, clavicle (collar bone), and accompanying muscles as they leave the thorax (chest) and enter the shoulder.”

Cervical Radiculopathy – A compression of the nerve roots in the neck.

Ulnar Nerve Entrapment – A compression of the ulnar nerve in the wrist.

Symptoms of MSDs or CTDs

The following symptoms may involve the back, shoulders, elbows, wrists, or fingers.  If symptoms last for at least one week or if they occur on many occasions a doctor should be consulted. 

  • Numbness,
  • Decreased joint motion,
  • Swelling,
  • Burning,
  • Pain,
  • Aching,
  • Redness,
  • Weakness,
  • Tingling,
  • Clumsiness,
  • Cracking or popping of joints

MSDs can be caused by work and non-work activities

These disorders can result from work and other than work activities that involve repetitive motions or sustained awkward postures, such as sports or hobbies. 

“These painful and sometimes crippling disorders develop gradually over periods of weeks, months, or years. . .Work and non-work activities may together contribute to cumulative trauma disorders.  These disorders can also be aggravated by medical conditions such as diabetes, rheumatoid arthritis, gout, multiple myeloma, thyroid disorders, amyloid disease and pregnancy.”

I was a court reporter for 10 years then became an inventor. I invented The Buttpillow™ and was granted a patent called the "Pillow with Cantilever Supports." At the same time, I also submitted a patent for "The Carpal Tunnel Chair," which I was advised I did not get. After R&D on The Buttpillow™, the patent for the "Ergonomic Seating Cushion" was filed and later amended to include an embodiment for women during pregnancy. The USPTO granted the "Ergonomic Seating Cushion" patent in late 2002. Subsequently, in 2003, I also invented Ergosoft™ break reminder software to remind people to take breaks with an Ergo-Tip™ so people can identify and minimize ergonomic risk factors around them.
