Abstract


Objective: To ascertain isometric knee extensor muscle strength prediction formula using hand-held dynamometer (HHD) through modified aneroid sphygmomanometer (MAS). Isometric knee extensor muscle strength examination is required to diagnose and evaluate quadriceps femoris weakness treatments.

 

Methods: This was a quantitative observational and correlational analysis study. The design used in the study was cross-sectional. Isometric knee extensor muscle strength was measured by using HHD and MAS. Correlational tests were performed to investigate the correlation between HHD and MAS with other variables. Regression test was carried out to analyze knee extensor strength regression using HHD through MAS. This study was conducted at Department of Department of Physical Medicine and Rehabilitation, Faculty of Medicine, Padjadjaran University-Dr. Hasan Sadikin General Hospital in the period of December 2015–February 2016 enrolled 25 healthy females aged 23–52 years old as the subjects.

 

Results: The correlation between HHD and MAS was considered significant while age, weight, height, and body mass index (BMI) did not show correlation with HHD and MAS. The isometric knee extensor muscle strength using HHD could be predicted by generating the formula=0.1041xMAS.

 

Discussion: Isometric knee extensor muscle strength using HHD determined a correlation with MAS and could be predicted through the MAS values. Therefore, the formula discovered in this study is only suitable for females.
