Changes in posture: a case study of a dental hygienist's use of magnification loupes

Evidence suggests that using magnification loupes will improve the posture of dental clinicians, thus decreasing work-related musculoskeletal disorders. The purpose of this case study was to document the experiences of a dental hygienist during a four week acclimatization period.

Documentation was comprised of self-reports from the dental hygienist's reflective journaling and postural measurements made by a trained observer using Branson's Posture Assessment Instrument (BPAI), a validated posture assessment instrument. Journal reports and postural measurements were made prior to the use of the magnification loupes and over the subsequent three week trial.

Use of the magnification loupes was a positive experience. The BPAI results indicated a positive change in neck and low back posture. Further trials of the effectiveness of magnification loupes in reducing musculoskeletal disorders with this occupational group are recommended.
