The Effect of Paraffin Treatment with Exercise on Muscle Strength and Fatigue of the Hand According to the Use of Smartphone

Purpose: This study examined the effects of a paraffin treatment with exercise on the muscle strength and fatigue of the hand according to the use of smartphones.Methods: The measurement subjects were 30 healthy males in their 20s who were divided randomly into the control and paraffin treatment groups.A typing exercise using a smartphone was performed.The pinch grip force was measured to evaluate the muscle strength of the thumb, and muscle fatigue analysis using electromyography was performed to analyze muscle fatigue.Results: The functional changes to the arm and the fatigue of the hand through the use of a smartphone were examined to determine the effects of the paraffin treatment.The dominant hand-pinch grip force test did not show a significant difference, but the non-dominant hand-pinch grip force test showed a significant difference between the groups (p= 0.030).In the dominant hand fatigue test, there was a significant difference between the groups (p= 0.037).In the non-dominant hand, there was a significant difference between time (p= 0.012) and the groups (p< 0.001). Conclusion:The effects of paraffin intervention on the hand muscle strength and fatigue due to repeated use of the smartphone were confirmed.These results can be used as a basis for clinical use and can be a guide for the correct use of smartphones, which are essential in modern life.
