    Opis:
    The head is an important element of the biokinetic chain. Under physiological conditions, it should extend along the midline of the body. Due to its location and the fact that it constitutes approx. 6% of the total body weight, many authors believe it has a significant impact on its functioning. The aim of this study was to conduct a systematic literature search and to synthesize the evidence of the impact of the head posture on the functioning of the human body. A systematic review was conducted within 3 databases: PubMed, Medline OVID, and EBSCO, using the following terms: “forward head,” “posture,” “position,” and “neck.” For the analysis, scientific articles published after 2013 were selected. A total of 16 studies matched the inclusion criteria of this systematic review. Their results have proven that the position of the head has a significant effect on the human body. Research findings show that abnormal head position changes affect muscle activity, proprioception, the pattern of breathing and neck pain. This is the first systematic review of the relationship between the head posture, and the functioning of the human body. The results of this study seem to be promising if used in therapeutic practice.

    Opis:
    ObjectivesThe objective of this study was to explore the relationship between seat armrest height and human neck comfort when using a smartphone while sitting on a passenger seat during the flight.Material and MethodsThe authors used a wireless angle-measuring instrument and subjective comfort scale to evaluate the changes of head flexion angle and neck comfort level of 24 young smartphone users in an aircraft simulated cabin.ResultsThe study results indicated that using a smartphone while sitting on a passenger seat during the flight would pose a larger discomfort to the neck, and the discomfort would be higher for gaming than reading tasks. Seat armrest height is related to the comfort level of the neck when using a smartphone, increasing the height of the armrest can effectively alleviate discomfort in this state.ConclusionsConsidering the prevalence of passengers using smartphones in aircraft, a seat armrest that can be properly adjusted in height, which can effectively reduce the risk of passenger head flexion angle and neck discomfort.

    Opis:
    Objectives The head constitutes 6% of the total body weight, which is linked to the cervical spine and all other joints through the kinematic chain by various muscles. The forward head posture is one of the most common postural disorders and seems to be especially dangerous. The goal of the work was to assess the impact of 4 weeks of training neck and nape muscles on the head posture. Material and Methods The subjects were 20 participants, who performed neck exercises for 20 days. The head posture in a sagittal and frontal plane was assessed photogrammetrically twice: before and after the exercises. The following have been used for the assessment: craniovertebral (CV) angle, head tilt angle (HT), and frontal head tilt angle (FHT). Results After a 20-day program of neck and nape exercises the values of specific angles were compared. The results indicated significant changes in the head posture. In the sagittal plane: the average value of the CV angle before the training was 47.17°, and 50.82° after the training; the average value of the HT angle before the exercises was at 20.99°, and 24.31° after. In the frontal plane the average value of the FHT angle before the exercises was at 2.71°, and after 20 days of training the average value of this angle decreased to 2°. Conclusions The results demonstrate that a short, home-based targeted exercise program can improve head posture. Int J Occup Med Environ Health. 2019;32(1):43–51

    Opis:
    Introduction Factors such as prolonged sitting at work or improper posture of head during work may have a great role in neck pain occurrence among office employees, particularly among those who work with computers. Although some studies claim a significant difference in head posture between patients and pain-free participants, in literature the forward head posture (FHP) has not always been associated with neck pain. Since head, cervical and thoracic postures and their relation with neck pain has not been studied in Iranian office employees, the purpose of this study was to investigate the relationship between some work-related and individual factors, such as poor posture, with neck pain in the office employees. Material and methods It was a cross-sectional correlation study carried out to explore the relationship between neck pain and sagittal postures of cervical and thoracic spine among office employees in forward looking position and also in a working position. Forty-six subjects without neck pain and 55 with neck pain were examined using a photographic method. Thoracic and cervical postures were measured using the high thoracic (HT) and craniovertebral (CV) angles, respectively. Results High thoracic and CV angles were positively correlated with the presence of neck pain only in working position (p < 0.05). In forward looking position, there was no statistically significant difference between the 2 groups (p > 0.05). Conclusions Our findings have revealed that office employees had a defective posture while working and that the improper posture was more severe in the office employees who suffered from the neck pain.
