OBJECTIVE This study compared the relationship between some clinical factors and the size of neck flexors in participants with or without chronic neck pain. DESIGN In this case-control study, the correlation between flexor endurance capacity as well as thickness, cross-section area, and shape ratio of longus colli/capitis and sternocleidomastoid muscles(More)
OBJECTIVE The purpose of this study was to compare the effect of abdominal hollowing (AH) and abdominal bracing (AB) maneuvers on the activity pattern of lumbopelvic muscles during prone hip extension (PHE) in participants with or without nonspecific chronic low back pain (CLBP). METHODS Twenty women with or without CLBP participated in this(More)
The aim of this study was to systematically review the evidence on respiratory function changes in patients with chronic neck pain. MEDLINE, Elsevier, ProQuest, PubMed, Scopus, Springer, and Google scholar electronic databases were explored thorough December 2015. English-language studies investigating cervical musculoskeletal and respiratory parameters in(More)
The aim of this randomized controlled trial was to assess the effect of an occupational therapy protocol of teaching the usage of adaptive devices to older individuals in Iran who have had a total hip replacement as compared with conventional occupational therapy on functional outcomes and independence.
