Inclusion Criteria

To be included in the study, the subjects with Active-MTrPs (A-MTrPs) must have experienced low back pain consistently over the past 3 months prior to the investigation and did not receive any physical therapy for at least 3 months. The cause of the back pain was diagnosed by an orthopedic physician to be low back dysfunction, due to postural imbalances, where an X-ray and MRI ruled out any spinal involvement. Subjects with Lantent-MTrPs (L-MTrPs) were pain-free subjects (they had no low back pain over the past 3 months), however they were referred for treatment for other conditions. Normal (20-24.9) and overweight (25-29.9) body mass index subjects were included in the study.

Exclusion Criteria

Exclusive criteria included active rheumatoid arthritis, fractures and structural deformities of trunk, hip, knee and ankle joints, neurological symptoms, disc prolapse, previous spinal surgery, pregnancy and body mass index of class II to III.

Primary Outcome Measures

Name	Time	Method
Tissue strain of MTrPs and its surrounding myofasical structure as well as the strain ratio by vibration sonoelastography[Directly after clinical identification of MTrPs by palpation and algometric measurements]

Secondary Outcome Measures

Name	Time	Method
Vibration sonoelastography assessed stiffness through a colored image, where the blue color represented the stiffest tissue, while the green, yellow and red represented the softer tissue.[Directly after clinical identification of MTrPs by palpation and algometric measurements];2-Dimensional grey scale ultrasound (B-mode), was implemented on the clinically identified MTrPs to assess echogenicity of MTrPs and surrounding myofasical structure. [Directly after clinical identification of MTrPs by palpation and algometric measurements];After completion of the imaging procedure by both modes, the images were printed out and a second radiologist was asked to identify, locate and score the MTrPs on the 2-Dimensional grey scale ultrasound image; where he was blinded from the colored vibration sonoelastography image at first, then he was shown the colored E-mode image and was asked to locate and score MTrPs again. This was done to measures accuracy of both modes.[After completion of the imaging procedure by both modes]
