We are looking for a strong method for the measurement of core muscle strength, which is reliable and valid in patients with chronic low back pain.

They stated that ' there is not a research-proven, valid testing regimen for core stability. However, Shirley Sahrmann has proposed a test called the Sahrmann Core Stability Test which is the most common test of function. It involves the use of a pressure cuff placed under the lumbar spine to measure one’s ability to maintain pelvic neutral while performing five exercises of progressive difficulty. '

However, there are many problematic issues regarding the concept of core muscle!
Please check the following link which is an interview with Prof Peter O'Sullivan talking about core stability

Good Luck!
I would look at the textbook by Dr. Stuart McGill "Low back disorders: Evidenced-based prevention and rehabilitation" (3rd ed). Dr. McGill, in my opinion, is likely one of the most prolific scholars in the study of low back disorders from a biomechanical perspective. I agree that core is a term that has an unclear definition but certainly has some traction in the popular press.
Hi Syed
Are you looking for a clinical measure or diagnostic measure.

The use of the ultrasound imaging (USI) is very interesting and not invasive. The use of ultrasound to assess muscle morphology.

An another my article: " The use of RUSI in the clinical practice is recommended for understand the relationships between
motor control and muscular functionality, to enhance the performance by increasing
the feedback and to document the benefits of a specific therapeutic approach
[17]. It includes a program of core strengthening/stabilization [18]. It is
expected that core exercises will attempt to allow the patient to control pelvic
position and motion to minimize symptoms while standing and walking"

Best regards and success in your study.
Dear dr.syed .I am also with giovana about RUSI technique. To make it precise and simple you follow the isolated muscle contraction by this technique. i had my own research done on this which is about transverse abdominus muscle contraction after giving a specialized physiotherapy exercise for abdomen.the paper is under peer review. the other techniques also mentioned above has good reliabilty and validity. hope it helps
The best way in my opinion is
Stuart mcgill core endurance test battery
It's evidence based, and invented by the pioneer if our age in core stability
