Does Manual Therapy Provide Immediate Improvement in Lumbar Range of Motion?

Not Applicable

Completed

• Conditions: N/A Healthy Individuals

• Registration Number: NCT05926674
• Lead Sponsor: New York Institute of Technology

Brief Summary

The goal of this clinical study is to determine if manual therapy can improve lumbar mobility in healthy individuals.

The main questions it aims to answer are:

* Is there an immediate local spinal effect?

* Is there an associated distal effect?

Researchers will compare an experimental group and a control group to examine the effects.

Detailed Description

Upon consent, participants will be assessed for lumbar spine mobility using inclinometers, hamstring flexibility using the active knee extension test and the modified sit-and-reach test, and ease of lifting a small, weighted object. After baseline measures are recorded, the participants will receive an intervention that will be either therapeutic (myofascial release) or sham (non-therapeutic hand placement). The choice of intervention received will be previously determined through the use of randomization software. The intervention provided will be applied to the low back and last for a total of 10 minutes. Immediately following the intervention, participants will again be assessed for lumbar spine mobility, hamstring flexibility, and ease of lifting a small, weighted object as noted above.

Primary Outcome Measures

Name	Time	Method
Lumbar Range of Motion	3 minutes	Upon arrival, the participant will be greeted and directed to the research room. The participant will be instructed to stand comfortably with their feet shoulder width apart, followed by one inclinometer placed at the level of S2 and the other 15cm above S2 by the designated researcher. The placement of the inclinometers is necessary to establish proper measurement of the lumbar spine, independent of outside influence. Inclinometers are valid and reliable tools for measuring lumbar ROM. Lumbar flexion will be measured first, followed by lateral flexion to the left and right. Lumbar ROM will be measured before and after each treatment.
Active Knee Extension test	3 minutes	The test is performed supine with the tested leg bent to 90° of supported hip flexion. The participant will be asked to actively extend his or her knee as fully as possible. Any lag from full extension will be measured with a standard goniometer. This test is a valid and reliable tool for hamstring length assessment. An extension lag of greater than 20° indicates a lack of hamstring flexibility. This will be performed on both lower extremities before and after each treatment.
Modified Sit and Reach test	3 minutes	The modified sit and reach test is a valid and reliable tool for assessing hamstring flexibility. This assessment will be implemented by the designated researcher. The modified sit and reach test will be administered before and after each treatment.
Functional Movement Assessment	1 minute	Each participant will be asked to perform a low-level functional activity (picking up a light-weight object) to help identify any perceived change in ability following the intervention.
