Spine Kinematics And Muscle Activities In Non-Specific Chronic Low Back Pain Subgroups In Sitting, Mansoor Ahmed Alameri

Loma Linda University Electronic Theses, Dissertations & Projects

Background: Although, non-specific chronic low back pain (NSCLBP) has been associated with motor control impairments, little is known about the possible driving mechanisms of pain development overtime during prolonged sitting period. Therefore, the purpose of this study was to examine the differences in lumbosacral postures and muscle activities in adults with and without NSCLBP, and their role on pain development during a 1-hour of prolonged sitting task.

Methods: Twenty NSCLBP subjects with motor control impairment (MCI) [10 classified as having flexion pattern (FP) disorder, and 10 with active extension pattern (AEP) disorder], and 10 healthy controls participated in …

Inter-Rater Reliability Of Lumbar Segmental Instability Tests And The Subclassification, Faisal Mohammad Alyazedi

Loma Linda University Electronic Theses, Dissertations & Projects

Objectives: This study investigated the inter-rater reliability of three structural end-range lumbar segmental instability tests with the highest positive Likelihood Ratio against flexion-extension radiographs, and three functional mid-range clinical tests that predict the success of lumbar stabilization exercises in patients with recurrent or chronic low back pain (R/CLBP). It also investigated the reliability of lumbar segmental instability subclassification as: Functional, Structural and Combined Instability. Method: 40 adult with R/CLBP patients (30 men and 10 women), 18 to 80 years of age, underwent repeated measurements of specific clinical tests for structural or functional lumbar segmental instability. Results: Other than the Lack …
