Measuring Deep and Superficial Multifidus and the Activation Pattern During Dynamic Task Correlating With Trunk Stability Ability and Functional Performance in Different Ages Asymptomatic and Unspecific Low Back Pain Adult

• Conditions: Low Back Pain

• Registration Number: NCT04772950
• Lead Sponsor: National Taiwan University Hospital

Brief Summary

The first propose of the study is to understand the contraction of deep and superficial multifidus in patients with non-specific low back pain and the elderly. The second purpose of the study is to understand the relationship between the multifidus and the functional performance in patients with non-specific low back pain and the elderly. The hypothesis is that the patients with non-specific low back pain and the elderly have less ability to contract the deep multifidus then asymptomatic adults and younger adults. Besides, the multifidus is correlated to the functional performance.

Primary Outcome Measures

Name	Time	Method
Countermovement jump test	3 minutes	The subjects start from an upright standing position, makes a preliminary downward movement by flexing at the knees and hips, then immediately extends the knees and hips again to jump vertically up off the ground. The distance which the subjects jump for will be recorded.
Disability index	5 minutes	use Oswestry Disability Index
Timed up and go test	3 minutes	Examiner will record the seconds the subjects spend in the test including standing up, walking, turn around and sit down.
Change of deep multifidus	10 minutes	change of deep multifidus during contraction by using ultrasound image
Change of superficial multifidus	10 minutes	change of superficial multifidus during contraction by using ultrasound image
Sahrmann five-level core stability test	5 minutes	Examiner will use stabilizer pressure biofeedback unit to detect whether there is lumbar motion during different levels of lower extremities movement.
Rotatory stability test	3 minutes	Rotatory stability test is one of the test from functional movement screen. Subjects will start in quadruped position and move the extremities to maintain the spine in neutral position.
Sit to stand test	3 minutes	Subjects will repeat 5 times sit to stand and the seconds subjects spend will be recorded.
