Study design: A cross-sectional non-experimental study. Objectives: To collectively detect the reliability and feasibility of the five types of clinical tests that have been used to measure endurance of the trunk muscles in subjects with and without low back pain (LBP) and identifY the sensitivity of each test to predict the probability of the occurrence ofLBP.



Post exercise proteinuria and increased urinary Gamma-Glutamyl transferase (GGT) levels can be indicative of exercise-induced renal damage. The aim of this investigation is to study the effect of one session of intensive training on renal damage markers and compare their values to those 6 hours after training.



The purpose of this study was to compare the effects of end range loading (ERL) vs harmonic technique (HT) on patients with chronic low back pain (LBP).

Study Design: A multifactorial cross-sectional nonexperimental design. Objectives: To collectively investigate the association among 17 mechanical factors and occurrence of low back pain (LBP). Background: Several physical characteristics, based on assumptions, clinical findings, and scientific experiments, have been associated with the development of LBP. Controversy exists regarding the degree of association between some of these physical characteristics and LBP. Information regarding the degree of association of each factor to LBP is needed for effective prevention and appropriate treatment strategies.

Objective: To determine if combining intermittent cervical traction with conventional physical therapy methods is more effective than using conventional approaches alone in the improvement of the grip strength and treatment of the patients with unilateral cervical 7 (C7) radiculopathy.

Design: Randomized controlled trial (RCT).

Setting: An outpatient physical therapy clinic, University of Social Welfare and Rehabilitation Science, Iran.
