The aim of the paper was to determine a correlation between the weight of a child’s backpack, their body weight, and certain features of their body posture.Material and Methods. The study group consisted of 109 children, all aged seven years. The parameters of body posture were determined using the Zebris Ultrasonic System.Results. The number of children carrying a school backpack in accordance with recommendations was 44 subjects (40.37%). Statistically significant changes were found in the total length of the spine (Z=2.223,p=0.026) and between backpack weight and changes in the following parameters: the total length of the spine (rs=-0.3999,p=0.017), the length and the angle of the lumbar lordosis (rs=-0.3352,p=0.049), the angle of the lumbar lordosis (rs=-0.5065,p=0.002), and the sacral angle (rs=-0.4279,p=0.010).Conclusions. Wearing a backpack heavier than 10% of one’s body weight can cause shallowing of the lumbar lordosis and a tendency towards a vertical position of the sacrum. Monitoring the weight of children’s school backpacks and enabling them to leave books and notebooks at school would probably be beneficial in reducing the daily burden put on children’s spines.

Ankyloglossia, commonly known as tongue-tie, is the most common disorder of tongue morphology characterized by aberrant attachment of the lingual frenum. This study aimed to provide a comprehensive literature review and evaluate the effectiveness of various laser wavelengths in the surgical treatment of patients with ankyloglossia. An electronic screening of PubMed and the Cochrane Central Register of Controlled Trials (CENTRAL) databases was conducted on 8 November 2021. The following search terms were used to review the available data on the subject of interest: (ankyloglossia OR tongue tie OR short lingual frenulum OR lingual frenectomy OR lingual frenulectomy OR lingual frenotomy OR lingual frenulotomy) AND laser. The use of lasers in ankyloglossia treatment resulted in shorter procedure time, reduced indications for general anesthesia, reduced administration of postoperative analgesics, fewer sutures or none needed, reduced postoperative bleeding, and improved healing. Despite many advantages, this method has its clinical limitations: it requires the use of expensive equipment; well-trained personnel familiar with lasers; and personal protective equipment for the patient, caregiver, operator, and assistant. The laser procedure does not eliminate the need for myofunctional exercises and work with a speech therapist.

The purpose of the study was to investigate correlations between parameters of anteroposterior spinal curvatures in the sagittal plane, measured with the use of photogrammetric technique and inclinometer in healthy elderly women.

Background. Spinal cord injuries are one of disability in Poland and in the world. Methods: 80 subjects with a transverse injury of the cervical spinal cord were enrolled in the study. The study group included men aged 20–50, 33.1 ± 7.5. A total of 40 (50%) of the subjects comprised the physically active group (AG)—subjects doing wheelchair sport twice a week for 90 min a day. The physically inactive group (IG) comprised 40 (50%) subjects who had not participated in any sports activities. Statistical analyses were carried out using Shapiro-Wilk W-test and Mann-Whitney U test. Results. Significant differences were found between the physically active and inactive men with regard to their functionality status. The biggest differences were found for turning over (p < 0.001) and in adopting a sitting position (p < 0.001). Persons in the AG group had better results in all assessed activities. The biggest differences were observed in the field of toilet and dressing up: tooth-brushing p < 0.007 and washing the top part of the body p < 0.002. Conclusions. People participating in regular physical activity–wheelchair rugby–after spinal cord injury have a better relationship with better fitness, greater independence and a better functional status.

Aim: The study was designed to assess the effects of surface instability in the response of the balance control system in children and youths with visual impairment (BL) and in normally sighted controls (NE). Materials and Methods: The empirical research study involved 80 individuals, aged from 6 to 20 years, with a mean age of 14.37 (±4.68), including 40 blind individuals and a randomly selected control group 40 normally sighted. Stabilometric measurements were performed with the use of the Platform CQ Stab 2P, with eyes open (EO) and closed (EC) on the solid surface, and then, the same procedure was performed on the platform covered with 1-centimetre-thick foam. Results: Statistical analyses (Wilcoxon matched-pairs test, Mann–Whitney U test) of the results identified during the trials reveal the following findings in the BL group in the EO and EC tests. The results of the foam surface test were higher and the differences were statistically significant in the BL group (sway path EO p = 0.009, EC p = 0.006; mean amplitude EC p = 0.030; mean velocity EO p = 0.009, EC p = 0.006; sway area EO p = 0.017, EC p = 0.009; and number of COP deflections along the sagittal plane EO p = 0.004). No similar correlations were observed in the NE group, except for the mean amplitude EO p = 0.033 and sway area EO p = 0.030. There was one difference between the BL and the NE group for the mean amplitude parameter, p = 0.018, in a solid surface test with open eyes. The results were higher in the BL group. Conclusions: The present study showed no worse balance in the BL group than in the NE group but worse performance on the foam than without it. It indicates the need to develop body balance skills in blind people by improving their proprioceptive sensitivity. In everyday life and training, blind people should experience exteroceptive stimuli, different textures, and unstable surfaces as much as possible.
