SUMMARY:When One Size Doesn’t Fit All: Efficacy assessment of an engineeri
 ng control for endoscopic procedures
DESCRIPTION:Ke Ding, Anas Kachlan, Paula Baluyut, and Carolyn M. Sommerich
  (The Ohio State University)\n\nStudies report an elevated prevalence of e
 ndoscopy-related musculoskeletal disorders in gastroenterologists.  Interv
 entions primarily address work environment and work organization, not tool
  design (the endoscope).  This study evaluated an add-on adjustable suppor
 t strap designed to reduce the workload of the user’s left hand, which ope
 rates the endoscope’s control section.  Study participants (4 women, 7 men
 ) were experienced in endoscopy. After practicing, to familiarize them wit
 h the colonoscopy simulator, scope, and support strap, each participant pe
 rformed two simulated colonoscopies with the support strap and two without
  (within-subjects counter-balanced design). Effects of the support strap w
 ere assessed using normalized muscle activity (nEMG) from surface electrod
 es over finger and wrist flexors and extensors and trapezius m., video, an
 d usability data. With the strap, nEMG was reduced in most muscles for 3 p
 articipants (all women); mixed results for 4, and no reduced nEMG for 4 ot
 hers (all men).  Mode of ratings of usability, usefulness, and desirabilit
 y were 7, 5, 5, respectively (7=very good).  Results suggest the potential
  for benefits for some users.\n\n
