Development of integrated jaw-neck motor function in children at 6, 10 and 13 years of age compared to adults: A kinematic longitudinal study.

BACKGROUND: The functional integration of the jaw and neck motor systems, of great importance to everyday oral activities, is established in early childhood. Detailed characterisation of this developmental progress is largely unknown. OBJECTIVE: To establish developmental changes in jaw-neck motor function in children over the ages 6-13 years compared to adults. METHODS: Jaw and head movement kinematics during jaw opening-closing and chewing were longitudinally recorded in 20 Swedish children (8 girls) at 6 (6.3 ± 0.4), 10 (10.3 ± 0.3) and 13 (13.5 ± 0.7) years of age and 20 adults (9 women, 28.2 ± 6.7). Movement amplitudes, jaw movement cycle time (CT), coefficient of variation (CV) and head/jaw ratio for amplitudes were analysed. Linear mixed effect analysis and Welch's t-test were used. RESULTS: Children showed pronounced movement variability and longer CT at 6 and 10 years old during opening and chewing (p < .001). Compared to adults, 6-year-olds showed higher head/jaw ratios (p < .02) and longer CT (p < .001) during opening and chewing, and higher CV-head (p < .001) during chewing. Whereas 10-year-olds showed larger jaw and head amplitudes (p < .02) and longer CT (p < .001) during opening, and longer CT (p < .001) and higher CV-head (p < .001) during chewing. For 13-year-olds, longer CT (p < .001) during chewing was found. CONCLUSION: Children showed pronounced movement variability and longer movement cycle time at 6-10 years and developmental progress in jaw-neck integration from 6 to 13 years, with 13-year-olds displaying adult-like movements. These results add new detailed understanding to the typical development of integrated jaw-neck motor function.

Jaw-neck movement integration in 6-year-old children differs from that of adults.

BACKGROUND: A functional integration between the jaw and neck regions during purposive jaw movements is well described in adults, but there is a lack of knowledge of such integration during jaw function in children. OBJECTIVES: To determine the movement integration between the jaw and neck during jaw motor tasks in 6-year-olds, whether there is a difference between children and adults. METHODS: Jaw and neck movements were recorded with an optoelectronic 3D system in 25 healthy 6-year-olds (12 girls, 13 boys) and 24 healthy adults (12 women, 12 men) during paced jaw opening-closing and self-paced gum chewing. Jaw and neck movement amplitudes, intra-individual variation in movement amplitude, ratio between neck-jaw movement amplitudes and movement cycle time were analysed. Differences between children and adults were evaluated with Mann-Whitney U test for independent samples. RESULTS: Compared to adults, 6-year-old children showed larger neck movement amplitudes (P = .008) during chewing, higher intra-individual variability in amplitudes of jaw (P = .008) and neck (P = .001) movements, higher ratio between neck-jaw movement amplitudes for jaw opening-closing (P = .026) and chewing (P = .003), and longer jaw movement cycle time (P ≤ .0001) during the jaw opening-closing task. CONCLUSION: Despite integrated jaw-neck movements in 6-year-old children, the movement pattern differs from that of adults and may be interpreted as an immature programming of jaw-neck motor behaviour. The well-integrated movements observed in adults most likely develop over years, perhaps into adolescence, and needs further research including well-controlled longitudinal studies to map this development in order to provide appropriate age-related clinical treatment for functional disorders.

Nursing Diagnoses Panorama in a Swedish Forensic Psychiatric Setting Using NANDA-International Taxonomy.

More than 1,000 Swedish hospital beds are occupied by patients in forensic psychiatric settings; their average length of hospitalization is 3-7 years. In this context, nursing diagnoses could be extremely useful to make nursing care structured, measurable, and internationally comparable. The study aimed to describe nursing diagnoses in a Swedish forensic psychiatric setting. METHODS: Data were collected from electronic patient records of 55 patients in a medium-secure forensic psychiatric setting in Sweden. Anonymized data were entered into a database where entries were transformed into figures. Descriptive statistics were used, and frequencies, means, and percentages were calculated. The variables employed were characteristics and related factors, according to NANDA-International (NANDA-I) and International Statistical Classification of Dieseases and Related Heatlh Problems, 10th Revision (ICD-10), diagnoses. RESULTS: The patients had between 1 and 13 NANDA-I diagnoses each. Forty-one of the 55 patients had psychosis as the primary ICD-10 code. The identified nursing diagnoses described the patients' status upon arrival in the forensic psychiatric setting. Of the 55 patients, entries in the patient records describing 300 signs and symptoms (i.e., characteristics and related factors) were found. From these signs and symptoms, 371 entries that fit NANDA-I diagnoses were identified, representing 20 different NANDA-I diagnoses. CONCLUSION: NANDA-I diagnoses individualize patient care, making care person centered. NANDA-I is used all over the world and has the potential to make nursing care structured, measurable, and internationally comparable.
