Etiologic Factors of Temporomandibular Disorders: A Systematic Review of Literature Containing Diagnostic Criteria for Temporomandibular Disorders (DC/TMD) and Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) from 2018 to 2022.

This study aims to conduct a systematic analysis of literature published between 1 January 2018 and 1 September 2022, exploring factors influencing the progression or development of temporomandibular disorders (TMD), diagnosed using the Diagnostic Criteria for Temporomandibular Disorders (DC/TMD) or Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD). Three electronic databases were reviewed to identify papers that examined TMD factors using DC/TMD or RDC/TMD. Inclusion criteria encompassed original research published in English between 1 January 2018 and 1 October 2022, online, and complete DC/TMD or RDC/TMD studies on human participants aged 18 or older. Two authors independently assessed the risk of bias using The Joanna Briggs Institute (JBI) Analytical cross-sectional studies' Critical Appraisal Tool. Of 1478 articles, 11 were included. The studies revealed strong associations between TMD and factors such as female, poor sleep quality, depression, oral parafunction, anxiety, somatization, and anatomical features. However, variables such as education, living conditions, socioeconomic status, marital status, chronic pain, and stress did not exhibit statistically significant correlations. Based on the obtained data, it can be concluded that the causes of TMD are largely related to psychological factors, which supports the biopsychosocial theory of the disorder.

Comparison of the six-minute walk test performed over a 15 and 30 m course by children with cerebral palsy.

BACKGROUND: The aim of this study was to compare performance on the six-minute walk test (6MWT) performed over 15 m and 30 m courses by children and youths with cerebral palsy (CP). METHODS: Children and youths with CP at Gross Motor Function Classification System levels I-IV performed the 6MWT in a straight 15 m-long corridor (first trial) and 30 m-long corridor (second trial). The intraclass correlation coefficient (ICC) and Bland-Altman plots were used to evaluate the agreement between the 6MWT results for the two corridor lengths. RESULTS: We included 82 children and youths with CP (36 girls, 46 boys), with a mean age of 11.7 years (SD 4.2, range 5-22 years). There was high agreement between the results of the two 6MWTs: ICC 0.93 (95% confidence interval 0.76-0.97). The total walking distance was longer for the 30 m course (median 399 m, range 44-687 m) than the 15 m course (median 357 m, range 24-583 m). CONCLUSIONS: We observed good agreement for the performance of the 6MWT in the 15 m and 30 m courses, although the total walking distance was greater for the 30 m course. We recommend that the same distance is used when evaluating changes in walking ability for an individual child. Both distances are appropriate when measuring endurance in children and youths with CP.

Analysis of the Relationship Between Regulation Disorders of Sensory Processing (RDSP) and the Development of the Gait Function and Motor Learning Processes in Children and Adolescents with Cerebral Palsy.

1. These results correlate with the outcomes of other studies on the relationship between sensory impairment and motor skills. 2. The study may contribute to the identification of more predictors of the effectiveness of rehabilitation of patients with CP, which can be used in the longer term to forecast the effects of therapy and the development of personalized medicine, as manifested in comprehensive therapeutic approaches (e.g. supplemented with sensory integration therapy).

Assessment of the relationship between Val66Met BDNF polymorphism and the effectiveness of gait rehabilitation in children and adolescents with cerebral palsy.

Cerebral palsy (CP) is associated with the non­progressive damage of upper motor neurons, which is manifested by a variety of symptoms, particularly motor and functional deficits. During the rehabilitation of patients with CP, attention is paid to improving mobility which can have a significant impact on the child's development. The effectiveness of rehabilitation depends on the plasticity of the nervous system, which may be genetically determined. Of importance are the various polymorphisms of the brain derived neurotrophic factor (BDNF) gene. It has been shown that the Val/Val genotype may predispose children to greater improvements in function and its maintenance. However, subjects with the Met allele showed a reduced tendency to improve their motor functions but had significantly better results on indirect tests assessing gait function. Fifty subjects with CP participated in this study. They were divided into two groups by genotype and examined on their rehabilitation progress in terms of improved gait function. The results correlated with other studies describing the relationship between the BDNF genotype and learning motor functions in CP, and with numerous studies on the relationship between BDNF genotype and neuroplasticity in stroke patients. This research provides a basis for the identification of genetic biomarkers in patients with CP which can be used to predict the effects of rehabilitation therapy and help with the development of personalized treatments.

Parents and Caregivers Satisfaction After Palliative Treatment of Spastic Hip Dislocation in Cerebral Palsy.

Objectives: Pain appearance is one the most common complication of spastic hip disease in children with cerebral palsy (CP). It determines child and caregiver quality of life and life priorities. Reconstruction hip surgery should be considered as a treatment of choice. Some clinical conditions give the inability to perform such a procedure. In our paper, we would like to present four palliative methods of spastic hip dislocation treatment in children with CP. Material: We analyzed four groups of patients treated because of hip pain. Inclusion criteria were pain appearance (visual analog scale-11 or numeric rating scale-11) and hip joint dislocation (migration percentage >80%). All patients were admitted to our department between 2008 and 2018. In the first group, patients were treated only by steroid injections to hip joints; in the second group, patients were recruits after hip interposition arthroplasty with shoulder spacer; in the third group, they were patients after valgus subtrochanteric osteotomy (Schanz); and in the fourth group, these were patients after proximal femoral resection (Castle procedure). The minimal follow-up time was 2 years. The first group consisted of 15 patients (15 hips) with a mean age of 15.5 (8-17) years; the second group, 20 patients (24 hips) with a mean age of 14.2 (9-22.6) years; the third group, 22 patients (24 hips) with a mean age of 13.5 (7-20.5) years; and the fourth group, 10 patients (15 hips) with a mean age of 12.9 (7-17.6) years. Methods: Radiological evaluation was based on a standardized anteroposterior X-ray of the hip joints. Pain severity before surgery and at the last follow-up time was measured by visual analog scale-11. Parents or caregivers were asked about their child's pain during sitting, perineal care, and rest. During the visit, all caregivers were asked about treatment satisfaction (no 0 to max 10) and if they would decide again for the same surgery. Results: In all groups of patients, we observed a decrease in pain complaints. The observed reduction of pain in the first group was from 7.88 (4-10) to 3.08 (0-8) (p = 0.05), but results of injection were observed only for 4 months (2-8), and it has to be repeated (average: two times). In the second group, level of pain was reduced from 4.93 (1-10) to 0.93 (0-5) (p < 0.001); in the third group, from 6.22 (3-10) to 0.59 (0-6) (p < 0.001); and in the fourth group, pain reduces from 5.43 (2-10) to 2.13 (0-5) (p < 0.001). Observed changes concerned mostly sitting position and perineal care. The complication rate was in the second group, 6 of 24 cases of extraarticular ossification; in the third group, 2 of 24 cases with extraarticular ossification, two cases of revision surgery. In the fourth group, two cases needed another femoral resection. In the first group, five patients died during follow-up time, so they were excluded from the study. In the steroid injection group, parents' treatment evaluation was 6.83 (0-10), and only in three cases that they would resign from the treatment. In the hip interposition arthroplasty group, caregivers' evaluation was 7.41 (0-10), and in five cases, parents did not accept the surgery. In the Schanz osteotomy group, parents' evaluation was 5.9 (0-10), and in eight cases, caregivers would not repeat surgery. In the proximal femoral resection group, satisfaction was the highest, 8.3 (3-10), and only two parents would not decide for surgery again. Conclusion: All procedures can be considered as palliative treatment options for pain complain in a spastic hip joint dislocation in children with CP. Steroid injections to the hip joint need to be repeated, and with the follow-up time, it becomes less effective. Steroid injection seems to be the treatment of choice for patients with general anesthesia contraindications. Interposition arthroplasty of the hip joint seems to give better final results, but the highest parents' satisfaction surprisingly was observed in the proximal femoral resection group, but differences were not statistically significant.

Interrater reliability for unilateral and bilateral tests to measure the popliteal angle in children and youth with cerebral palsy.

BACKGROUND: Short hamstring muscles can cause several problems for children with cerebral palsy. The results of the clinical measurement of hamstring length are often used in decision-making about treatment of children with cerebral palsy. There are different ways of performing this measurement. The aim of this study was to evaluate the interrater reliability of the unilateral and bilateral measurement of the popliteal angle in children and youth with cerebral palsy. METHODS: Two methods for estimating hamstring length using unilateral and bilateral measurements of the popliteal angle were applied in children with cerebral palsy. Both tests were applied bilaterally by two independent examiners on the same day for each child. The intraclass correlation coefficient (ICC) was calculated to evaluate the interrater reliability of both measurements. Seventy young people with cerebral palsy (32 females, 38 males, mean age 10 years 8 months, range 5-22 years) at Gross Motor Function Classification System levels I (n = 17), II (n = 31), III (n = 12) and IV (n = 10) were included. RESULTS: The interrater reliability was good for both measurements. The ICC values were 0.80 on the right and 0.86 on the left for the unilateral popliteal angle, and 0.82 on the right and 0.83 on the left for the bilateral popliteal angle. CONCLUSIONS: Both unilateral and bilateral measurement of the popliteal angle is a reliable method for estimating hamstring length in children and youth with cerebral palsy.
