    Ergonomics In Dissection Ergonomics In Dissection Presentation Transcript

    • ERGONOMICS of Dissection Presented by: Patrick Tafoya Director of Educational Services Medical Hair Restoration Orlando, Florida
      • The term “ergonomics” is derived from two Greek words: “ ergon ”, meaning work and “ nomoi ”, meaning natural laws.
      • Ergonomics is the study of human capabilities in relationship to work demands.
    • Ergonomic Principles
      • All work activities should permit the worker to adopt several different, but equally healthy and safe postures.
      • Where muscular force has to be exerted it should be done by the largest appropriate muscle groups available.
      • 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 .
    • THE PROBLEM...
      • 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.
      • Any attempt to improve workplace conditions can have only limited success if this issue is ignored.
    • Repetitive Motion Disorders
      • 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.
      • 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.
    • Repetitive Motion Disorders
      • Carpal tunnel syndrome
      • Bursitis
      • Tendonitis
      • Epicondylitis
      • Ganglion cyst
      • Tenosynovitis
      • Trigger finger
    • Repetitive Motion Disorders
      • RMDs occur most commonly in the hands, wrists , elbows, and shoulders.
      • 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.
    • Treatment for RMDs usually includes reducing or stopping the motions that cause symptoms.
      • Taking breaks
      • Stretching and relaxation exercises
      • Applying ice to the affected area
      • Medications: pain relievers, cortisone, and anti-inflammatory drugs.
      • Splints: relieve pressure on the muscles and nerves
      • Physical therapy: relieve the soreness and pain
      • In rare cases, surgery may be required to relieve symptoms and prevent permanent damage
      • Developed ergonomic programs: help workers adjust their pace of work and arrange office equipment to minimize problems.
      • Without treatment, RMDs may result in permanent injury and complete loss of function in the affected area.
    • 100+ MHR Dissectors
      • Loupes
      • 2003: 8 cases RMD
      • 2004: 5 cases RMD
      • 2005: 7 cases RMD
      • Microscopes
      • 2006: 0 cases RMD
      • 2007: 0 cases RMD
      • 2008-Present: 2 cases RMD
      • (exclusive dissector and implanter)
    • Microscopy
      • Standard recommendations to control hazards associated with microscopy:
      • Place microscope toward the edge of the work surface to prevent a poor operating position (more upright posture).
      • Elevate the microscope. This can help position the operator in a more upright posture and reduce rounding of the shoulders and neck.
      • Maintain neutral spine.
    • Microscopy
      • Use an ergonomically designed chair that provides adequate back support, adjustable height, and adjustable seat angle.
      • Use armrests to support the operator's forearms.
      • Avoid leaning wrists and elbows on sharp edges.
      • Adequate room under the work surface so the operator can pull the chair up to the ocular(s).

    • Microscopy
      • 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.
      • Provide footrests.
      • Provide sit-stand seats for areas where there is restricted leg room.
      • Encourage frequent breaks as well as stretching exercises.
    • Instrumentation
      • Forceps (straight vs. angled)
      • Cutting Blades (scalpel vs. prep razors)
    • Dissection The Single Edge razor provides a more natural ergonomic position of the hands and wrist.
    • Dissection The 45 degree Jeweler’s Forceps provides a more natural ergonomic position of the hands and wrist.
    • Mom Was Right … Posture IS Important
      • 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.
    • A Productive Partnership
      • Poor working conditions are bad news for both employees and employers—resulting in physical suffering and adverse economic impact.
      • A partnership among staff, employers, and ergonomics principles can help redesign the workplace to meet the capabilities and potential of your hair technicians.
