Abstract

|
Objectives: The purpose of this study was to measure estheticians' grip and pinch strength in the hand parts and identify related factors according to general characteristics.
Methods: A Jamar dynamometer was used to measure grip strength and a Jamar pinch gauge was used to measure tip, palmar and lateral pinch strength. General data were collected through a questionnaire survey among 116 estheticians from 31 skin care centers and spas.
Results: The subjects' mean grip strength was 23.95 kgf for the right hand and 23.42 kgf for the left hand with the dominant right hand recording slightly higher mean grip strength. Their mean pinch strength was the highest with lateral pinch(right 4.89 kgf, left 4.69 kgf), which was followed by palmar pinch(right 3.77 kgf, left 3.88 kgf) and tip pinch(right 2.29 kgf, left 2.25 kgf), in that order.
Conclusions: The grip and pinch strength of the hand parts was high when estheticians' commonly used both hands for massage instead of just one. The use of both hands is recommended to protect the hand parts during massage.
