RESUMO

BACKGROUND: The purpose of this study was to analyze the relationship between body posture and sagittal dental overjet in children before and after early orthodontic treatment with removable functional orthodontic appliances. METHODS: Angle Class II patients (mean age 8.2 ± 1.2 years; 29 males and 25 females) with a distinctly enlarged overjet (> 9 mm) were retrospectively examined regarding body posture parameters before and after early orthodontic treatment. In addition, changes in overjet were investigated with the aid of plaster models. Forms of transverse dysgnathism (crossbite, lateral malocclusions) and open bite cases were excluded. Body posture parameters kyphosis, lordosis, surface rotation, pelvic tilt, pelvic torsion and trunk imbalance were analyzed by means of rasterstereographical photogrammetry to determine, if the orthodontic overjet correction is associated with specific changes in posture patterns. RESULTS: In nearly all patients an overjet correction and an improvement regarding all body posture and back parameters could be noted after early orthodontic treatment. Overjet reduction (- 3.9 mm ± 2.1 mm) and pelvic torsion (- 1.28° ± 0,44°) were significantly (p < 0.05) and moderately correlated (R = 0.338) with no significant associations found for the other posture and back parameters (p > 0.05). CONCLUSION: Overjet reduction during early orthodontic treatment may be associated with a detectable effect on pelvic torsion.

RESUMO

The psychomotor disadaptation syndrome (PDS) was first described 34 years ago by the geriatric research team from Dijon, France. This syndrome was initially called "psychomotor regression syndrome". It was renamed PDS in the 1990s following considerable advances in the understanding of its pathophysiology and management. Since the 2000s, a condition known as sub-cortical-frontal dysfunction (syndrome sous-cortico-frontal) has become synonymous with PDS. Effective management of PDS requires a multidisciplinary approach that includes physicians, physiotherapists, psychologists and the entire geriatrics healthcare team.

RESUMO

Background: Neck pain (NP) is a common work-related disorder, with high prevalence in the profession of teaching. The daily duties of a school teacher involve head-down postures while reading and writing, which expose them to the risk of developing NP. Deep cervical flexor (DCF) muscles have been reported to have lower endurance in patients with cervical impairment, which has additionally been associated with disability. There is limited evidence regarding the efficacy of training of DCF muscles in occupational NP. The objective of this study was to investigate the effects of DCF muscle training on pain, muscle endurance, and functional disability using pressure biofeedback in school teachers with NP. Methods: Sixty-five teachers (age, 25-45 years) with more than 5 years of teaching experience participated in this study. They were randomly divided into two groups: the experimental (E) and control (C) groups. In the E group, the subjects underwent DCF muscle training using pressure biofeedback in addition to conventional exercises for neck pain, while those in the C group underwent conventional exercises only. Pain, muscle endurance, and disability were measured at day 0 (before the treatment) and days 14 and 42 after the treatment. Endurance of DCF muscles was measured by the craniocervical flexion test using pressure biofeedback, pain intensity was measured using the numeric pain rating scale, and functional disability was assessed using the neck disability index questionnaire. This study was performed in accordance with CONSORT guidelines. Results: On day 0, there were no significant differences in the age, pain, muscle endurance, and disability levels between the groups. After initiating the intervention, although there were improvements in both groups, there was a statistically significant improvement in muscle endurance, pain, and disability in subjects who received additional training with pressure biofeedback. Conclusions: Besides increasing muscle endurance, specific training of DCF muscles in addition to conventional exercises can improve neck pain and functional disability. These results should be further correlated clinically. A dedicated time for exercises at school could help prevent the development of NP in teachers. This trial is registered with ClinicalTrials.gov NCT03537300 May 24, 2018 (retrospectively registered).

RESUMO

INTRODUCTION: This study aimed to assess the static posture in patients with Angle Class II and III malocclusions in the first 2 months after orthognathic surgery. METHODS: This was a longitudinal observational study. Eligible participants were adult patients who had an indication of orthognathic surgery (bilateral sagittal split osteotomy of the maxilla and/or mandible, can be associated or not with genioplasty). Thirty-five patients were evaluated from the orthognathic surgery group (OSG) and control group (CG). Measurements in OSG were performed at 3 time points: preoperative orthognathic surgery (P0), first postoperative month (P1), and second postoperative month (P2). Static posture was evaluated using the PostureScreen Mobile (PostureCo Inc, Trinity, Fla) application in 4 views. RESULTS: Patients with Angle Class II malocclusion in the OSG evidenced a tendency to a left hip translation at P1 with a significant difference at P2 in the anterior view (P = 0.052). In the right lateral view, patients with Angle Class II malocclusion in the OSG at P1 presented an accentuated anterior shoulder translation when compared with CG (P <0.001). At P1, patients with Angle Class II malocclusion in the OSG showed a significant anterior knee translation compared with the CG and OSG at P0 and P2 (P <0.001 for all). Patients in the OSG with Angle Class III malocclusion presented an average posterior head translation in the right lateral view at P1 when compared with those in the CG and OSG at P0, who presented an anterior translation (P = 0.0008). CONCLUSIONS: These findings suggest a realignment of static posture in the first 2 months after orthognathic surgery.

RESUMO

OBJECTIVE: To fluoroscopically evaluate the effects of head posture and sedation on the laryngopharyngeal anatomic structures in dogs. ANIMALS: 6 clinically normal Beagles (mean age, 6.2 years; mean weight, 10.4 kg). PROCEDURES: Each dog was sedated and placed in right lateral recumbency, and fluoroscopic examinations were performed with flexed, neutral, and extended head postures (FHP, NHP, and EHP, respectively). During 3 respiratory cycles, the angle between the basisphenoid bone and nasopharyngeal dorsal border (ABN), thickness of the soft palate, diameter of the nasopharyngeal lumen (DNL), overlapping length between the epiglottis and soft palate, and distance between the epiglottis and tympanic bulla (DET) were measured and percentage difference in the DNL (PDNLD) during a respiratory cycle was calculated. RESULTS: For the FHP, NHP, and EHP, median ABN was 91.50° (interquartile range [IQR], 86.75° to 95.00°), 125.00° (IQR, 124.50° to 125.50°), and 160.00° (IQR, 160.00° to 163.50°), respectively, with no significant differences between ABN and posture angle. For the FHP, median DNL and DET significantly decreased, compared with values for the NHP, and median thickness of the soft palette significantly increased. For the EHP, the minimal DNL and DET significantly increased, and the median overlapping length between the epiglottis and soft palate significantly decreased, compared with values for the NHP. The PDNLD significantly increased and decreased with FHP and EHP, respectively, compared with the PDNLD with NHP. Sedation did not affect upper airway structure changes. CONCLUSIONS AND CLINICAL RELEVANCE: Results indicated that head posture significantly affected the laryngopharyngeal structures in dogs. Fluoroscopic examination of the upper respiratory tract of a dog should be performed with an NHP to minimize posture-induced changes in measurements.

RESUMO

CONTEXT: Evidence concerning a systematic, comprehensive injury risk assessment in the elite swimming population is scarce. OBJECTIVE: To evaluate the quality of current literature regarding clinical assessment techniques used to evaluate the presence and/or development of pain/injury in elite swimmers and to categorize objective clinical assessment tools into relevant predictors (constructs) that should consistently be evaluated in injury risk screens of elite swimmers. DATA SOURCES: PubMed, Embase, Scopus, CINAHL, SPORTDiscus, PEDro, and the Cochrane Library Reviews were searched through September 2018. STUDY SELECTION: Studies were included for review if they assessed a correlation between clinic-based objective measures and the presence and/or development of acute or chronic pain/injury in elite swimmers. All body regions were included. Elite swimmers were defined as National Collegiate Athletic Association, collegiate, and junior-, senior-, or national-level swimmers. Only cohort and cross-sectional studies were included (both prospective and retrospective); randomized controlled trials, expert opinion, and case reports were excluded, along with studies that focused on interventions, performance, or specific swim-stroke equipment or technology. STUDY DESIGN: Systematic review and qualitative analysis. LEVEL OF EVIDENCE: Level 3. DATA EXTRACTION: PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines were utilized at each phase of review by 2 reviewers; a third reviewer was utilized for tie breaking purposes. Qualitative analysis was performed using the Methodological Items for Non-Randomized Studies (MINORS) assessment tool. RESULTS: A total of 21 studies assessed the presence and/or development of injury/pain in 3 different body regions: upper extremity, lower extremity, and spine. Calculated average MINORS scores for comparative (n = 17) and noncomparative (n = 4) studies were 18.1 of 24 and 10.5 of 16, respectively. Modifiable, objectively measurable injury risk factors in elite swimmers were categorized into 4 constructs: (1) strength/endurance, (2) mobility, (3) static/dynamic posture, and (4) patient-report regardless of body region. CONCLUSION: Limited evidence exists to draw specific correlations between identified clinical objective measures and the development of pain and/or injury in elite swimmers.

RESUMO

Ergonomic research in the field of interventional radiology remains limited. Existing literature suggests that operators are at increased risk for work-related musculoskeletal disorders related to the use of lead garments and incomplete knowledge of ergonomic principles. Data from existing surgical literature suggest that musculoskeletal disorders may contribute to physician burnout and female operators are at a higher risk of developing musculoskeletal disorders. This review article aims to summarize the existing ergonomic challenges faced by interventional radiologists, reiterate existing solutions to these challenges, and highlight the need for further ergonomic research in multiple areas, including burnout and gender.

RESUMO

ABSTRACT: This study identified the effects of pursed-lip breathing (PLB), forward trunk lean posture (FTLP), and combined PLB and FTLP on total and compartmental lung volumes, and ventilation in patients with chronic obstructive pulmonary disease (COPD). Sixteen patients with mild to moderate COPD performed 2 breathing patterns of quiet breathing (QB) and PLB during FTLP and upright posture (UP). The total and compartmental lung volumes and ventilation of these 4 tasks (QB-UP, PLB-UP, QB-FTLP, PLB-FTLP) were evaluated using optoelectronic plethysmography. Two-way repeated measures ANOVA was used to identify the effect of PLB, FTLP, and combined strategies on total and compartmental lung volumes and ventilation. End-expiratory lung volume of ribcage compartment was significantly lower in PLB-UP than QB-UP and those with FTLP (P < .05). End-inspiratory lung volume (EILV) and end-inspiratory lung volume of ribcage compartment were significantly greater during PLB-FTLP and PLB-UP than those of QB (P < .05). PLB significantly and positively changed end-expiratory lung volume of abdominal compartment (EELVAB ) end-expiratory lung volume, EILVAB, tidal volume of pulmonary ribcage, tidal volume of abdomen, and ventilation than QB (P < .05). UP significantly increased tidal volume of pulmonary ribcage, tidal volume of abdomen, and ventilation and decreased EELVAB, end-expiratory lung volume, and EILVAB than FTLP (P < .05). In conclusion, combined PLB with UP or FTLP demonstrates a positive change in total and compartmental lung volumes in patients with mild to moderate COPD.

RESUMO

Huntington's disease (HD) is an inherited neurodegenerative disorder characterized by severe disruption of cognitive and motor functions, including changes in posture and gait. A number of HD mouse models have been engineered that display behavioral and neuropathological features of the disease, but gait alterations in these models are poorly characterized. Sensitive high-throughput tests of fine motor function and gait in mice might be informative in evaluating disease-modifying interventions. Here, we describe a hypothesis-free workflow that determines progressively changing locomotor patterns across 79 parameters in the R6/2 and Q175 mouse models of HD. R6/2 mice (120 CAG repeats) showed motor disturbances as early as at 4 weeks of age. Similar disturbances were observed in homozygous and heterozygous Q175 KI mice at 3 and 6 months of age, respectively. Interestingly, only the R6/2 mice developed forelimb ataxia. The principal components of the behavioral phenotypes produced two phenotypic scores of progressive postural instability based on kinematic parameters and trajectory waveform data, which were shared by both HD models. This approach adds to the available HD mouse model research toolbox and has a potential to facilitate the development of therapeutics for HD and other debilitating movement disorders with high unmet medical need.

RESUMO

According to several theories, the oro-facial sphere would be interconnected with the rest of the body justifying the requests for care to improve a body zone at a distance. The aim of this literature review was to look for potential distant links of dysmorphoses of the three dimensions of space according to the etiopathogenic theories and the data of science. We carried out a keyword search leading to 58 references. In the transverse dimension, the transverse maxillary hypoplasia and dissymmetry of the molar class of the transverse dimension would not induce a change in the distribution of the weight of the body on a stabilometric platform. In the vertical dimension, hyperdivergent patients have a decreased bite force, cephalic extension with respect to the spine, an extension of the base of the skull, and decreased cervical lordosis. In the anteroposterior dimension, skeletal classes II would be associated with increased cervical lordosis and posterior cephalic extension according to the « true vertical ¼ (inversely for classes III). The prevalence of dental classes II would be increased in scoliosis subjects. Studies with a low level of evidence (grade III, IV or even V) should be interpreted with caution because the simultaneous presence of concomitant anomalies does not allow us to conclude that there is a cause-and-effect relationship.

RESUMO

Noisy galvanic vestibular stimulation (nGVS) involves the application of a weak, noisy, electrical current to the vestibular end organs and their afferent nerves, through electrodes placed bilaterally over the mastoid process. Center of pressure (COP) sway was shown to decrease during nGVS under conditions of static standing posture. However, whether nGVS can improve balance functions other than the static standing posture remains unclear. This study aimed to elucidate the effects of nGVS on COP sway during one-legged standing. We randomly assigned 36 participants to either a control group (sham stimulation), a 0.2 mA group (nGVS at 0.2 mA), or a 0.4 mA group (nGVS at 0.4 mA). All participants were measured for COP sway standing on one leg, with open eyes, both before and during stimulation. In the 0.2 mA group, the sway path length, mediolateral mean velocity, and anteroposterior mean velocity decreased during stimulation compared with before stimulation. Conversely, no significant differences in COP sway were detected for either the control group or the 0.4 mA group. The stimulation effects for all COP sway parameters were significantly higher in the 0.2 mA group than in either the control group or the 0.4 mA group. The results of this study suggested that nGVS not only decreases COP sway during static standing postures but can also reduce COP sway during one-legged standing.

RESUMO

A 44-year-old male person with tetraplegia (C-5 AIS-A (American Spinal Cord Injury Association Standard Neurological Classification of Spinal Cord Injury Impairment Scale)) developed urinary tract infection and received appropriate antibiotic. Subsequently, he started sweating and shivering when he was sitting up; these symptoms resolved while lying on his back. Autonomic dysreflexia triggered by truncal movements continued to occur for 3 months. CT of the spine showed L5-S1 discitis. MRI of the spine showed diffuse marrow oedema in L5 and S1 vertebrae and a large abscess at L5/S1 level. Blood culture yielded Serratia marcescens sensitive to meropenem. Meropenem followed by ertapenem was given for 12 weeks. After 11 months, MRI showed resolution of discitis and epidural collection. The patient was able to sit up for 9 hours without developing autonomic dysreflexia. If a person with cervical spinal cord injury develops posture-related autonomic dysreflexia (eg, in sitting position, lying on sides or while hoisted), disco-vertebral pathology should be suspected.

RESUMO

Introduction: In the world, 75 million people require a wheelchair (W/C) but only between 5% and 15% of them have one. The WHO defines a W/C as adequate if it meets the needs of the user and their environment, offers appropriate seating and postural support and if it is safe and durable. Objective: The primary objective is to describe the seating, postural support and safety of W/Cs users who attend the I.Re.P kinesiology service. The secondary objective is to learn about their satisfaction with their W/Cs and related services. Subjects and method: The subjects were W/C users who attend the I.Re.P. kinesiology service. The W/Cs were evaluated following the WHO guidelines, and the satisfaction using the QUEST 2.0 questionnaire. Results: Within 30 patients, 21 were men aged around 48.17 years. Only 1 subject had all the correct measures of safety, seating and posture adjustment. 6 had all the correct measures for an adequate seating and 5 had all the safety measures. Regarding satisfaction, high scores have been found with respect to W/C and low scores with respect to related services. All in all, the total satisfaction got mostly medium and high scores. Conclusion: Only 1 subject out of the 30 evaluated complied with all the seating, postural adjustment and safety requirements necessary to consider an adequate W/C. Most subjects reported being more satisfied with their W/C than with the related services.

RESUMO

AIMS: The complex relationship between acetabular component position and spinopelvic mobility in patients following total hip arthroplasty (THA) renders it difficult to optimize acetabular component positioning. Mobility of the normal lumbar spine during postural changes results in alterations in pelvic tilt (PT) to maintain the sagittal balance in each posture and, as a consequence, markedly changes the functional component anteversion (FCA). This study aimed to investigate the in vivo association of lumbar degenerative disc disease (DDD) with the PT angle and with FCA during postural changes in THA patients. METHODS: A total of 50 patients with unilateral THA underwent CT imaging for radiological evaluation of presence and severity of lumbar DDD. In all, 18 patients with lumbar DDD were compared to 32 patients without lumbar DDD. In vivo PT and FCA, and the magnitudes of changes (ΔPT; ΔFCA) during supine, standing, swing-phase, and stance-phase positions were measured using a validated dual fluoroscopic imaging system. RESULTS: PT, FCA, ΔPT, and ΔFCA were significantly correlated with the severity of lumbar DDD. Patients with severe lumbar DDD showed marked differences in PT with changes in posture; there was an anterior tilt (-16.6° vs -12.3°, p = 0.047) in the supine position, but a posterior tilt in an upright posture (1.0° vs -3.6°, p = 0.005). A significant decrease in ΔFCA during stand-to-swing (8.6° vs 12.8°, p = 0.038) and stand-to-stance (7.3° vs 10.6°,p = 0.042) was observed in the severe lumbar DDD group. CONCLUSION: There were marked differences in the relationship between PT and posture in patients with severe lumbar DDD compared with healthy controls. Clinical decision-making should consider the relationship between PT and FCA in order to reduce the risk of impingement at large ranges of motion in THA patients with lumbar DDD.

RESUMO

Mandibular proprioception would influence postural control. The development of spatial references are governed by the same afferences. This work aims to clarify the role of mandibular proprioception, implicated in postural and spatial dysfunctions, in the control of cephalic posture and spatial repositories. 24 subjects received a vibration of the masseter and temporal muscles. Measurements of head position (HP) (video), subjective visual vertical (SVV) and line bisection (LB) were obtained with and without vibration. Without vibration, HP (0.31 ° ± 1.76 °) was negatively correlated with SVV (+ 0.23 ° ± 0.62 °, r22 = -0.44, p = 0.033); with vibration, HP on the opposite side to the stimulated muscle (t23 = 2.77, p = 0.011). There is a correlation between LB and SVV. Without vibration, the Müller effect is found for SVV. The pseudo-negligence is not found. With vibration, the error of the HP and the SVV go in the same direction. No effects on the LB. Conclusion: Beyond local responses, the vibration can evoke global and oriented responses.

RESUMO

Measuring the center of pressure (CoP) for a subject positioned on a force plate is one of the most commonly used tools to investigate balance. Several studies have proven a significant degradation of the body's stability after the age of 60. The conclusions, however, are based on a limited number of indicators and without systematic nonlinear analysis methods being used to evaluate the progression of CoP parameter values. Neither the change in CoP movement in subjects over 60 years of age nor the considerations of their body mass index (BMI) has been systematically evaluated by nonlinear methods so far. This study is based on one of the frequent methods for nonlinear evaluation - the Recurrent Quantification analysis. This article discusses the applicability of this method with regards to the evaluation of changes in postural stability of subjects over 60 years of age. Postural stability changes were evaluated using CoP motion and tested by the nonlinear method. For this research purpose, a group of 103 elderly women were selected and divided into age-respective groups of 60-69 years and 70-79 years old. Each age group was further divided into a subgroup of normal and overweight subjects according to their BMI. The following recurrent analysis parameters were employed in the evaluation of CoP motion in medial-lateral and anterior-posterior directions: determinism (DET), laminarity (LAM) and trapping time (TT). The results of the Wilcoxon test revealed a statistically significant difference between the values in parameters for the different age groups of overweight subjects almost in all the cases. Conversely, statistically significant differences between age groups rarely occurred in a subgroup of subjects with a normal BMI.

RESUMO

Infarcts involving the thalamus can yield many deficits, including sensory syndromes, altered consciousness, and cognitive disturbances, depending on the thalamic vascular territory involved. Isolated truncal contrapulsion due to pure thalamic infarct has been rarely reported. Truncal lateropulsion is a compelling sensation of being pulled toward one side that cannot be explained by weakness or limb ataxia. It is commonly reported in lateral medullary infarcts. It may occur with lesions that involve the peripheral vestibular system, brainstem, cerebellum, basal ganglia, ponto-mesencephalic, and thalamic lesions. We hereby report a 64-year-old woman who presented with truncal contrapulsion as the sole manifestation of an acute right lateral thalamic infarct.

RESUMO

Despite acromioclavicular (AC) joint injuries being common, there are still controversies about the treatment; nonoperative versus surgical, who to operate, when to operate, which technique to use, and which rehabilitation protocol to use. Orthopaedic surgeons are often faced with these patients fearing not regaining normal function and to some degree acceptable cosmetic outcomes. Despite increasing interest in surgical management of type 3 AC joint injuries, surgical management has not been demonstrated to yield superior functional outcomes compared with nonoperative treatment. Interestingly, studies have demonstrated that good outcomes are achieved with most surgical techniques even though they are all associated with loss of initial reduction. This brings into question whether surgery is necessary in the early phase and how we can mitigate the effects of gravity to maintain reduction. Studies that can aid surgeons in patient selection for treatment protocols (nonoperative versus surgical) and timing of surgery are needed. We recommend early surgery, and restricted rehabilitation, for high-grade acromioclavicular joint dislocation.
