Background Diagnoses and treatments based on movement system impairment syndromes
were developed to guide physical therapy treatment. Objectives This masterclass aims to …

Clinicians use forward bending and backward return in routine clinical examinations for
evaluating spine mobility. The magnitude and timing of lumbar spine and pelvic …

Although biomechanics plays a role in the development and perhaps the persistent or
recurrent nature of low back pain (LBP), whether biomechanics alone can provide the basis …

Background It is unknown if low back pain (LBP) outcomes are enhanced by classification-
specific treatment based on the Movement System Impairment classification system. The …

Background Based on the kinesiopathologic model, the Movement System Impairment (MSI)
classification of LBP has shown that repetitive movements could contribute to pathoanatomic …

The flexion-relaxation phenomenon (FRP) is frequently absent among non-specific chronic
low back pain (NSCLBP) patients. However, it is unknown whether this absence is intrinsic …

Background Prior studies have reported differences in lumbo-pelvic kinematics during a
trunk forward bending and backward return task between individuals with and without …

Study Design. A cross-sectional comparative study. Objective. The present study aimed to
investigate the relationship between the FR phenomenon asymmetry of lumbar muscles and …

Background The correlation between hamstring muscle shortening and nonspecific low
back pain and compensatory lumbar movements is still controversial. The purpose of this …

Objective The aim of the study was to determine whether gluteus medius muscle thickness
or activation differed between left and right sides and was associated with patellofemoral …
