Ergonomics In Dissection

  1. 1. ERGONOMICS of Dissection Presented by: Patrick Tafoya Director of Educational Services Medical Hair Restoration Orlando, Florida
  2. 2. ERGONOMICS... <ul><li>The term “ergonomics” is derived from two Greek words: “ ergon ”, meaning work and “ nomoi ”, meaning natural laws. </li></ul><ul><li>Ergonomics is the study of human capabilities in relationship to work demands. </li></ul>
  3. 3. Ergonomic Principles <ul><li>All work activities should permit the worker to adopt several different, but equally healthy and safe postures. </li></ul><ul><li>Where muscular force has to be exerted it should be done by the largest appropriate muscle groups available. </li></ul><ul><li>Work activities should be performed with the joints at about mid-point of their range of movement. This applies particularly to the head, trunk, and upper limbs . </li></ul>
  4. 4. THE PROBLEM... <ul><li>In order to put these recommendations into practice, a person would have to be a skilled observer of his or her own joint and muscle functioning and would have to be able to change his or her posture to a healthier one at will. </li></ul><ul><li>Any attempt to improve workplace conditions can have only limited success if this issue is ignored. </li></ul>
  5. 5. Repetitive Motion Disorders <ul><li>Repetitive motion disorders ( RMDs ) are a family of muscular conditions that result from repeated motions performed in the course of normal work or daily activities. </li></ul><ul><li>RMDs are caused by too many uninterrupted repetitions of an activity or motion, unnatural or awkward motions such as twisting the arm or wrist, overexertion, incorrect posture, or muscle fatigue. </li></ul>
  6. 6. Repetitive Motion Disorders <ul><li>Carpal tunnel syndrome </li></ul><ul><li>Bursitis </li></ul><ul><li>Tendonitis </li></ul><ul><li>Epicondylitis </li></ul><ul><li>Ganglion cyst </li></ul><ul><li>Tenosynovitis </li></ul><ul><li>Trigger finger </li></ul>
  7. 7. Repetitive Motion Disorders <ul><li>RMDs occur most commonly in the hands, wrists , elbows, and shoulders. </li></ul><ul><li>Over time, RMDs can cause temporary or permanent damage to the soft tissues in the body -- such as the muscles, nerves, tendons , and ligaments - and results in compression of nerves or tissue. </li></ul>
  8. 8. Treatment for RMDs usually includes reducing or stopping the motions that cause symptoms. <ul><li>Taking breaks </li></ul><ul><li>Stretching and relaxation exercises </li></ul><ul><li>Applying ice to the affected area </li></ul><ul><li>Medications: pain relievers, cortisone, and anti-inflammatory drugs. </li></ul><ul><li>Splints: relieve pressure on the muscles and nerves </li></ul><ul><li>Physical therapy: relieve the soreness and pain </li></ul><ul><li>In rare cases, surgery may be required to relieve symptoms and prevent permanent damage </li></ul><ul><li>Developed ergonomic programs: help workers adjust their pace of work and arrange office equipment to minimize problems. </li></ul>
  9. 9. <ul><li>Without treatment, RMDs may result in permanent injury and complete loss of function in the affected area. </li></ul>
  10. 10. 100+ MHR Dissectors <ul><li>Loupes </li></ul><ul><li>2003: 8 cases RMD </li></ul><ul><li>2004: 5 cases RMD </li></ul><ul><li>2005: 7 cases RMD </li></ul><ul><li>Microscopes </li></ul><ul><li>2006: 0 cases RMD </li></ul><ul><li>2007: 0 cases RMD </li></ul><ul><li>2008-Present: 2 cases RMD </li></ul><ul><li>(exclusive dissector and implanter) </li></ul>
  11. 11. Microscopy <ul><li>Standard recommendations to control hazards associated with microscopy: </li></ul><ul><li>Place microscope toward the edge of the work surface to prevent a poor operating position (more upright posture). </li></ul><ul><li>Elevate the microscope. This can help position the operator in a more upright posture and reduce rounding of the shoulders and neck. </li></ul><ul><li>Maintain neutral spine. </li></ul>
  12. 12. Microscopy <ul><li>Use an ergonomically designed chair that provides adequate back support, adjustable height, and adjustable seat angle. </li></ul><ul><li>Use armrests to support the operator's forearms. </li></ul><ul><li>Avoid leaning wrists and elbows on sharp edges. </li></ul><ul><li>Adequate room under the work surface so the operator can pull the chair up to the ocular(s). </li></ul>
  13. 13. Dissection <ul><li>Comparative views of </li></ul><ul><li>Loupes/Backlight and Microscopic Dissection </li></ul>
  14. 14. Dissection <ul><li>Comparative views of </li></ul><ul><li>Loupes/Backlight and Microscopic Dissection </li></ul>
  15. 15. Microscopy <ul><li>Adjust the location of work and the angle of the work piece in such a way that your body can maintain an unstrained, comfortable position with your arms, forearms, and shoulders relaxed. </li></ul><ul><li>Provide footrests. </li></ul><ul><li>Provide sit-stand seats for areas where there is restricted leg room. </li></ul><ul><li>Encourage frequent breaks as well as stretching exercises. </li></ul>
  16. 16. Instrumentation <ul><li>Forceps (straight vs. angled) </li></ul><ul><li>Cutting Blades (scalpel vs. prep razors) </li></ul>
  17. 17. Dissection The Single Edge razor provides a more natural ergonomic position of the hands and wrist.
  18. 18. Dissection The 45 degree Jeweler’s Forceps provides a more natural ergonomic position of the hands and wrist.
  19. 19. Mom Was Right … Posture IS Important <ul><li>Poor posture (held for long periods), poorly designed work areas, poorly adjusted chairs and sustained activity without breaks can all contribute to varying amounts of back, shoulder, and neck pain. </li></ul>
  20. 20. A Productive Partnership <ul><li>Poor working conditions are bad news for both employees and employers—resulting in physical suffering and adverse economic impact. </li></ul><ul><li>A partnership among staff, employers, and ergonomics principles can help redesign the workplace to meet the capabilities and potential of your hair technicians. </li></ul>
