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

National Taiwan University Hospital60 enrolled

Overview

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.

Outcomes

Primary Outcomes

Change of superficial multifidus

change of superficial multifidus during contraction by using ultrasound image

Time frame: 10 minutes

Change of deep multifidus

change of deep multifidus during contraction by using ultrasound image

Time frame: 10 minutes

Disability index

use Oswestry Disability Index

Time frame: 5 minutes

Timed up and go test

Examiner will record the seconds the subjects spend in the test including standing up, walking, turn around and sit down.

Time frame: 3 minutes

Sit to stand test

Subjects will repeat 5 times sit to stand and the seconds subjects spend will be recorded.

Time frame: 3 minutes

Countermovement jump test

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.

Time frame: 3 minutes

Sahrmann five-level core stability test

Examiner will use stabilizer pressure biofeedback unit to detect whether there is lumbar motion during different levels of lower extremities movement.

Time frame: 5 minutes

Rotatory stability test

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.
