Abstract

|
|
Background : Mobilization movements was applied with different forces and frequencies for different clinicians. Force transmission varies with frequency.
Objectives : The purpose of this study was to examine the effects of frequency- specific application of grade III PA movement on muscle tone and muscle activity around the lumbar vertebrae.
Design : A one group pretest-posttest design.
Methods : Twenty study subjects applied grades III of PA movement exercise of 0.5 Hz and 1 Hz with a force of 13 N around the 1st and 3rd lumbar vertebrae, and muscle tone and muscle activity were measured and compared before and after.
Results : This study showed that 0.5 Hz grade III PA activity exerted an effect on the decrease in muscle tone of the 1st and 3rd right and left lumbar muscles. It was found that 0.5 Hz affected the right side of L1 and 1.0 Hz affected the left side of L1 in near-activity when applying the grade III PA movement by frequency.
Conclusion : In the future, it will be necessary to investigate the effect of applying frequency according to various grades of PA movement.
