The Intra- and Inter-rater Reliabilities of the Forward Head Posture Assessment of Normal Healthy Subjects

Abstract

[Purpose] Assessment of posture is an important goal of physical therapy interventions for preventing the progression of forward head posture (FHP). The purpose of this study was to determine the inter- and intra-rater reliabilities of the assessment of FHP. [Subjects and Methods] We recruited 45 participants (20 male subjects, 25 female subjects) from a university student population. Two physical therapists assessed FHP using images of head extension. FHP is characterized by the measurement of angles and distances between anatomical landmarks. Forward shoulder angle of 54° or less was defined as FHP. Intra- and inter-rater reliabilities were estimated using Kendall’s Taub correlation coefficients. [Results] Intra-class correlation of intra-rater measurements indicated an excellent level of reliability (0.91), and intra-class correlation of inter-rater measurements showed a good level of reliability in the assessment of FHP (0.75). [Conclusion] Assessment of FHP is an important component of evaluation and affects the design of the treatment regimen. The assessment of FHP was reliably measured by two physical therapists. It could therefore become a useful method for assessing FHP in the clinical setting. Future studies will be needed to provide more detailed quantitative data for accurate assessment of posture.

The effect of a newly developed wheelchair with thoracic and pelvic support on cervical movement and muscle activity in healthy elderly women

“…FHP increases with age [20,21] and is higher in elderly than in young individuals [20][21][22][23]. FHP causes the posterior neck muscles to shorten, increases the load on the joints and ligaments, and weakens the muscles [6,24]. Eliminating FHP reduces the load on the neck.…”

The effect of forward head posture on muscle activity during neck protraction and retraction

“…Forward head posture (FHP) is one of the most common types of postural abnormality, and it is generally described as an anterior position of the head in relation to the vertical line of the body’s center of gravity 6 , 7 ) . Many researchers have reported that several factors, including headache, neck pain, and musculoskeletal disorders such as temporomandibular disorders or rounded shoulders, are related to FHP 1 , 8 ) . In addition, FHP leads to lengthening and weakness of the anterior cervical muscles as well as shortening of the posterior cervical muscles.…”

Does Taping Change Anterior Tilt of the Head? Rigid and Kinesio Taping

“…1 Özellikle masa başı çalışanlarda, bilgisayar önünde geçirilen süre boyunca yanlış pozisyonda oturma ve ergonomik olmayan fiziki koşullar, kişide başın anterior tilti dediğimiz üst servikal vertebraların öne, üst torakal ve alt servikal vertebraların arkaya eğim yaptığı yuvarlak omuzla birlikte olan postüre yol açar. [2][3][4] Bu yüzden boyun kas-iskelet problemleri ve servikal disfonksiyon; yuvarlak omuz postürü ve torakalkifoz ile ilişkili-dir. 3,5 Yuvarlak omuz postürü, yani omuzların öne pozisyonlanması, skapulaların protraksiyonu ile ilişkilidir ve bu durum torakal kifozda artışa neden olmaktadır.…”
