Postural stability is defined as the ability to maintain an upright position. It comes in two forms, static and dynamic. Static postural stability is when you are standing and not moving while dynamic stability is when you are moving or doing specific movements (Graves W, 2017). Considering postural stability as a sensorimotor process, it is conceivable that physical exercises, known to alter the peripheral proprioceptive system, the central processing of proprioception but also the force-generating capacity affects both the sensory and motor side of the process. (Akulwar and Mulgaonkar, 2017). Trunk extensors are physiologically postural muscles being rich in type 1 muscle fibers. The erectors spinae and multifidi are found to be tonically active in quiet standing and the erectors spinae contract eccentrically to control trunk flexion from a standing position and also when the head or upper limb is moved forward. (MacDonald D. et.al., 2006). It is suggested that although trunk extensor muscle strength is necessary for activities of daily living, its endurance has a very important role in spinal stability during prolonged physical activity and protects from injury (Granata KP et al., 2001). This study aimed to determine the relationship of trunk extensor muscle endurance on postural stability among the Physical Therapy students in UPH-DJGTMU. Specifically, if proven effective the results are beneficial to the respondents. The objective of the researchers is to determine if there is significant relationship between trunk extensor muscle endurance and Postural Stability after being tested using Bieriing-Sorensen Test and Functional Reach Test. This study utilized an experimental type of research that aimed to determine the relationship of trunk extensor muscle endurance on postural stability among students of College of Physical Therapy.


A total of fifty-one (51) physical therapy students of University of Perpetual Help-Dr. Jose G. Tamayo Medical University who have passed the required inclusion criteria set forth by the researchers were gathered as the respondents for the study. The study was held at Thera Lab, 5th floor of the Medical Building of UPH-DJGTMU. Biering-Sorensen Test was used to measure trunk extensor muscle endurance and postural stability variables were measured by using Functional Reach Test right after performing Biering-Sorensen Test. This test was performed at the 0.05 level 4 of significance. Based on the findings of the researchers, the measurements between Biering-Sorensen Test and Functional Reach Test yielded a very strong relationship(r=0.82) between the two variables and the relationship is significant (critical t-test 21.00). Therefore, based on the result of the study, the Biering-Sorensen Test or Trunk Extensor Muscle Endurance does have a significant relationship on Postural variables in terms of Functional Reach Test.
