Abstract
Background and Aim: The previous studies conducted that the contribution of lumbar spine segment and hip motion during functional activities of daily livings, however, it is still unknown whether different spinal segment and hip motion occur in a specific sequence during functional tasks. The current study aimed to identify the movement sequence of cephalocaudal and hip regions while performing several dominant daily activities.

Methods: Twelve male participants (mean age = 29.6 ± 4.2 years; weight = 73.4 ± 8.4 kg; height = 1.76 ± 0.08 meters) recruited in this study. Five Tri-axial accelerometer sensors used to collect data of a novel approach to understand the multicephalocaudal regions and hip movement sequences when performing several dominant daily activities.

Results: Regional sequences during flexion and extension tasks at starting phase of movement illustrated (92%) of participants move their head cervical region first as well as object lifting (80%). first. Regional sequences during standing-to-sitting task at starting phase of movement found (70%) of participants move their lumbar region first, while (78%) of participants during sitting-to-standing task moved their hip first.

Conclusions: This study indicates variations of movement sequence of cephalocaudal and hip regions at different phase. While the head-cervical region moved first in starting phase of flexion, extension, and lifting task, hip region moved first in the end phase of flexion, extension, and standing-to-sitting task.
