This meta-analysis investigated whether more negative psychological factors are associated
with less spinal amplitude of movement and higher trunk muscle activity in individuals with …

Objective To investigate the relationship between changes in volitional spinal movement
(including muscle activity) and changes in pain or activity limitation at the individual level in …

Purpose The flexion relaxation phenomenon (FRP) is characterized by the reduction of
paraspinal muscle activity at maximum trunk flexion. The FRP is reported to be altered …

Biofeedback is a process in which biological information is measured and fed back to a
patient and clinician for the purpose of gaining increased awareness and control over …

Abstract Background and Objectives The role of spinal movement alterations in low back
pain (LBP) remains unclear. This systematic review and meta‐analyses examined the …

Objective Although pain-related fear and catastrophizing are predictors of disability in low
back pain (LBP), their relationship with guarded motor behavior is unclear. The aim of this …

The flexion relaxation phenomenon (FRP) is characterized by the reduction of paraspinal
muscle activity at maximum trunk flexion. FRP is reported to be altered (persistence of spinal …

Objective To investigate the levels of kinesiophobia, physical activity, depression, disability,
and quality of life in patients with knee osteoarthritis. Design A cross-sectional study. Setting …

Background Among the main methods used to identify an altered flexion relaxation
phenomenon (FRP) in nonspecific chronic low back pain (NSCLBP), it has been previously …

This review sought to identify, critically appraise, compare, and summarize the literature on
the reliability, discriminative validity and responsiveness of the flexion relaxation ratio (FRR) …
