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

Work. 2010;35(4):467-76. doi: 10.3233/WOR-2010-0983.


Purpose: 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.

Methods: 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.

Conclusion: 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.
