Background. Idiopathic scoliosis is among the most common spinal disorders diagnosed in 1–3% of children and adolescents. Treatment choice is related to disease severity, with a Cobb angle of 20–40°, a corrective brace or physiotherapy can stop its progression. However, insufficient research has shown whether combined treatment is better than monotherapy.
Aim. To evaluate the effect of combining bracing and physiotherapy to reduce spinal deformity, improve quality of life and lung function, and compare the results with those of monotherapy. Determine the optimal duration of combined rehabilitation to reduce the angle of deformity.
Methods. Relevant articles published from 2014 to 2024 in the databases PubMed, Scopus, Cochrane (CENTRAL), Web of Science, and ScienceDirect were selected based on the PRISMA 2020 guidelines. Paediatric patients (up to 19 years, before skeletal maturity) diagnosed with idiopathic scoliosis (Cobb angle > 10°), undergoing combined bracing and physiotherapy, were studied.
Results. Of 2 729 articles, nine were included. The analysis showed a statistically significant change in the combined therapy group: mean difference –2.93 [–4.77; –1.09], p = 0.04, I2 = 57.33%. Long-term treatment effect size was –6.71 [–10.89; –2.53], p < 0.82, I2 = 0%, while short-term treatment showed no statistically significant result. Quality of life improved in the research group, with no significant change in most control group areas. Due to the high risk of bias, lung function changes were not assessed.
Conclusions. Combined therapy appears to reduce spinal deformity in children with idiopathic scoliosis and improve health-related quality of life, with better results than monotherapy. Longer treatment may improve Cobb angle correction but evidence is limited.

The sport of rodeo is recognized as a high velocity, high intensity activity with a wide range of varying dynamic movements occurring across different rodeo events. High velocities and extreme dynamic range of motion movements, compounded with uncooperative livestock, contribute to elevated risk of injury. While these factors are generally attributed to rodeo injuries, little is known regarding movement limitations of rodeo athletes.
# PURPOSE
Therefore, the purpose of the current investigation was to identify movement pattern differences among athletes from various rodeo events using the Functional Movement Screening (FMS™) test.
# METHODS
College rodeo athletes from a mid-size university in the southwest region were recruited as participants for this study. Athletes were categorized according to their respected rodeo event: steer wrestling (n = 12), breakaway roping (n = 44), goat tying (n = 17), barrel racing (n = 30), team ropers (n = 23) bronc riding (n = 18), tie down roping (n = 8), or bull riding (n = 10). All rodeo athletes completed an FMS™ test to establish movement efficiency. A General Linear Model was applied to assess event/group FMS™ mean differences to control for heterogeneity of variance across the groups. A repeated Measures ANOVA was utilized to illustrate variance in FMS™ scores within rodeo events.
# RESULTS
Study participants consisted of 162 collegiate rodeo athletes, including 71 males (m ± sd; age: 20.5 ± 1.35 years) and 91 females (20.2 ± 1.38 years). There was a significant interaction effect between event and FMS™ tests (F(7, 55) = 8.11, p \<.0.01) with robust standard errors applied. The aggregate FMS™ scores did not differ significantly (p = 0.438) between athletes of various rodeo events.
# CONCLUSION
These results suggest event specific movement patterns associated with various rodeo events may affect FMS™ test results for rodeo athletes. Additionally, event specific, preventative exercise prescription can be derived from these findings and may serve as a useful strategy for decreasing potential injury.

Subsequently, 200 participants with acute lower back pain episodes (7– 21 days) and sports participation were identified in each country and completed surveys (Step 2) about sociodemographic, pain, treatment characteristics, and causes/triggers of long-lasting acute lower back pain episodes.Results: In the United States, China, Russia, and Germany, respectively, 59%, 49%, 61%, and 63% of respondents reported ≥ 1 episode of nonspecific acute back pain in the previous 6 months. Average numbers of monthly nonspecific acute back pain episodes in the United States, Russia, Germany, and China were 2.5, 1.8, 1.3, and 0.8, respectively. Prevalence of acute lower back pain associated with sports/leisure activities ranged from 20% (Russia and Germany) to 46% (China). Onset of long-lasting acute lower back pain was between ages 30 and 33 years, limiting usual activities and reducing walking distance in 60% to 85% of respondents across all countries. Acute lower back pain started post-exercise within the first day for ≥ 75% of respondents. Most popular nonprescription and prescription treatments for acute lower back pain were creams/gels in Russia, creams/gels and oral painkillers in Germany, oral painkillers in the United States, and hot/cold patches in China.Conclusion: These results help to better understand acute back pain triggers, features, and treatment preferences among sports participants in different countries. Further research is warranted to develop preventative strategies.Trial Registration: Not applicable.Keywords: lower back pain, surveys and questionnaires, acute pain, sports

PurposeThis study aimed to investigate the effect of exercise intervention, and analyze exercise intervention strategies for adolescent depression through a meta-analysis of RCTs.MethodsAccordance to PRISMA guidelines, PubMed, Medline, EBSCO, Web of Science, SPORTDiscus, PsycINFO, ProQuest, and CNKI were searched for eligible records. Peer-reviewed studies were included if they met the following criteria: population (mean age of 10–18 years), intervention (physical activity, sport, or exercise), and outcomes (depression, adherence, ITT, dropout, adverse events, follow-up report). The protocol of this systematic review was registered in PROSPERO (CRD42022321683). Effect sizes calculations and methodological quality of exercise intervention (TESTEX scale) were carried out. The certainty of evidence was assessed by GRADE framework.ResultsThirteen randomized controlled trials were eligible for this review, which comprised a total of 433 adolescents. Compared with the control treatment, the effect of exercise on adolescent depression was moderate (SMD = −0.65, 95%CI: −1.03 to −0.27, p < 0.01). Heterogeneity was substantial (T2 = 0.30, I2 = 67%, p < 0.01). The moderating effect analysis showed that exercise intervention characteristics (organization form, exercise frequency, exercise intensity, exercise type, and single exercise session duration) of included studies varied greatly revealing multiple factors that may impact the antidepressant effect of exercise on adolescent depression (I2 > 50%, p < 0.05). Three studies show that the positive effect of exercise on reducing depression in adolescents remained 40 weeks after the intervention. Moreover, owing to the included studies contained methodological limitations, the certainty of evidence was reduced to moderate level.ConclusionThis study shows that exercise intervention has a moderate and sustained positive effect on adolescent depression. Our results recommended that adolescents with depression undertake moderate to high intensity group mixed exercise for more than 12 weeks, 20 to 60 min/time, more than 3 times/week. Additionally, our study also shows that the antidepressant effects remained for a long time after the end of exercise interventions. However, following the GRADE framework, we rated the certainty of evidence the primary meta-analysis as moderate evidence due to some limitations of included studies. Therefore, rigorous studies are still needed to verify the results.Systematic review registration[https://www.crd.york.ac.uk/PROSPERO/display_record.php?RecordID=321683], identifier [CRD42022321683].

Background: Closed finger flexor tendon pulley injuries occur most frequently in rock climbing but also during other heavy finger strength work or exercises. While single pulley injuries receive a conservative therapy, multiple pulley injuries often require a surgical repair, as otherwise they will lead to contracture and loss of range of motion and functionality. While established surgical techniques, which use bone encircling tendon graft techniques, were found to produce osteonecrosis of the phalanx, our new transosseous technique avoids this problem. Indications: All triple pulley injuries (A2,3,4) (grade-4b injuries) and double pulley injuries (A2,3 or A3,4) (grade-4a injuries) are indicated, if the injury is older than 10 days at the point of therapy start or the flexor tendons bowstringing is either not redressable in the ultrasound or extended. Also, grade-4a injuries are indicated, if a secondary contracture starts to build. Technique Description: Standard palmar-sided incision, followed by debridement of the tendon sheath, pulley flap, and, if applicable, scare tissue in between the flexor tendons and the bone is performed. Wire-guided 3.0-mm drill holes at the base phalanx at the level of the former distal portion of the A2 pulley are completed. Passing of the palmaris longus tendon through the drill hole and interlacing it as a “loop and a half” follows. Distal continuation through lacing the transplant through the remaining rims of the former pulleys and the flexor tendon sheath is then performed. Securing the repair after tendon gliding control to itself is completed. Postsurgically, the splint is immobilized for 2 weeks, followed by the use of a thermoplastic pulley support ring for 4 weeks with active mobilization. Results: No complications occurred during or after the surgery. In few cases, a restricted range of motion in the proximal interphalangeal (PIP) joint of the respective finger of up to 3 to 5 grade occurred. One patient, who had a presurgical PIP extension deficit of 30°, which was released during the surgery, developed over time again a 20° extension deficit. The functional outcome score ranged between good and excellent, with one case being only satisfactory. The sport-specific outcome score was either good or excellent for all patients, with one patient with contracture where it was satisfactory. No osteonecrosis of the phalanx was recorded. Discussion: For multiple pulley ruptures, various surgical techniques are described. We favored a modified “loop and a half” technique with a distal continuation to the A3 pulley. This combines the advantages of the “loop and a half” technique, as the strongest, and the Weilby repair, as the most functional repair. We recently noticed some cases with osseous necrosis of the phalanx following this repair, likely due to the high pressure of the circulation of the tendon graft onto the bone and its blood vessels. Therefore, we have modified our procedure into a transosseous repair, which is presented in this article. This approach was first evaluated in a cadaver study to exclude a potential risk of osseous failure (fracture) during stress caused by the drill hole. After ruling out this risk, the transosseous technique became our standard approach, as it combines the advantages of the “loop and a half” technique with those of the Weilby repair and decreases the pressure onto the dorsal cortex of the fingers base phalanx and thus the risk of osteonecrosis.

BackgroundRecent evidence suggests that the use of orthopedic manual therapy (OMT) may lessen the subsequent risk of low back pain (LBP), but this association has not been examined among pregnant women who are at higher risk of LBP. This study aims to determine whether the addition of OMT to conventional LBP treatment before pregnancy could decrease the subsequent risk of LBP during pregnancy.MethodsFrom Taiwan's National Health Insurance Research Database, we identified 68,960 women, 20–55 years of age, with first pregnancy between 2001 and 2012. We then performed a nested case-control study in which 3,846 women with newly diagnosed LBP were matched to 3,846 controls according to age and cohort entry year. Multivariate conditional logistic regression was employed to estimate the association between OMT use before pregnancy and LBP during pregnancy.ResultsOMT users had a lower risk of LBP than did non-users, with an adjusted OR of 0.86 (95% CI, 0.78–0.93). Subgroup analysis showed that women with high intensity use of OMT treatment prior to pregnancy reported the lowest level of LBP during pregnancy by nearly 30%.ConclusionThe pre-pregnancy use of OMT treatment significantly decreased LBP risk during pregnancy, especially with high-intensity use. Thus, clinicians may consider recommending OMT for pregnant women to avoid possible obstetric complications during the pregnancy.

The autonomic nervous system (ANS) maintains homeostasis through the balance of the sympathetic and parasympathetic subsystems or divisions. Currently, analysis of heart rate variability (HRV) offers an indirect, non-invasive assessment of ANS function. An irregular lifestyle and stress are known to affect ANS balance, influencing many diseases. Moreover, ANS disorder plays an important role in climacteric symptoms in menopausal females. The purpose of this study was designed to assess the effects of yoga practice sessions (herein referred to as “yoga”) on ANS function and focused on the relationship between ANS function and subject age or personal history of yoga. A total of 113 healthy females participated in this study. They attended a 90-120 minute yoga practice session conducted by a well-qualified instructor. ANS function was assessed before and after the yoga practice session by HRV power spectral analysis. As a result, in females, yoga reduced fatigue by primarily improving sympathetic activity. In addition, the LnHF values tended to be increased after yoga only in the over-60y (60 years) group. Furthermore, there were individual differences in the amount of change in the sympathetic and parasympathetic activity values. In females with a low activity level before yoga, values were increased; whereas values decreased in females with a high activity value before yoga. In subjects with ≥5-year history of yoga, there was no significant correlation between the ANS parameters and subject age. Our study suggests that yoga for females supports well-balanced ANS function, and that the continuation of yoga over a period of time contributes to an improvement in ANS function.
The value of experimental animals (white rats) erythrocytes in pathogenesis of parodontium inflammatory disease was searched. The dynamics of Hb changes, erythrocytes number and hematocrit were surveyed. Periodontitis was moulded by special diet. When periodontitis developed oxidative stress and enhanced generation of reactive oxygen species were observed as well as changes in the number of erythrocytes, hemoglobin and erythrocyte indices. The latter were caused by membrane destructive processes in erythrocytes, decrease in their absolute number due to hemolysis, and changes in hematocrit due to blood redistribution.

Abstract Background The chiropractic profession has a long history of internal conflict. Today, the division is between the ‘evidence-friendly’ faction that focuses on musculoskeletal problems based on a contemporary and evidence-based paradigm, and the ‘traditional’ group that subscribes to concepts such as ‘subluxation’ and the spine as the centre of good health. This difference is becoming increasingly obvious and problematic from both within and outside of the profession in light of the general acceptance of evidence-based practice as the basis for health care. Because this is an issue with many factors to consider, we decided to illustrate it with an analogy. We aimed to examine the chiropractic profession from the perspective of an unhappy marriage by defining key elements in happy and unhappy marriages and by identifying factors that may determine why couples stay together or spilt up. Main body We argue here that the situation within the chiropractic profession corresponds very much to that of an unhappy couple that stays together for reasons that are unconnected with love or even mutual respect. We also contend that the profession could be conceptualised as existing on a spectrum with the ‘evidence-friendly’ and the ‘traditional’ groups inhabiting the end points, with the majority of chiropractors in the middle. This middle group does not appear to be greatly concerned with either faction and seems comfortable taking an approach of ‘you never know who and what will respond to spinal manipulation’. We believe that this ‘silent majority’ makes it possible for groups of chiropractors to practice outside the logical framework of today’s scientific concepts. Conclusion There is a need to pause and consider if the many reasons for disharmony within the chiropractic profession are, in fact, irreconcilable. It is time to openly debate the issue of a professional split by engaging in formal and courageous discussions. This item should be prioritised on the agendas of national associations, conferences, teaching institutions, and licensing/registration as well as accreditation bodies. However, for this to happen, the middle group of chiropractors will have to become engaged and consider the benefits and risks of respectively staying together or breaking up.

Suaugusieji turi daug vaiko negatyvaus elgesio korekcijos priemonių. Jie gali vaikui kantriai paaiškinti, kodėl jo
veiksmai yra netinkami ir kokio elgesio tikisi iš savo vaiko arba be komentarų taikyti įvairias bausmes. Aptarsime tik
fi zines bausmes, nes nėra vieningos mokslininkų nuomonės apie tokių priemonių pasekmes vaiko asmenybės raidai,
o suaugusieji jas ypač dažnai taiko vaiko elgesio korekcijai.
Tyrimo tikslas — suaugusiųjų požiūrio į fi zines bausmes, kaip į pedagoginę elgesio korekcijos priemonę, tyrimas.

Admission The first successful attempt to use stimulants neuro modulation properties date back to the first half of the twentieth century. Due to the high technological limitations, the use of peripheral nerve electrostimulators the early eighties
XX century was relatively small and involved few patients treated primarily due to neuropathic pain and patients psychosurgical.
The development of modern batteries in the eighties of the twentieth century, standardization and implementation process to achieve consensus on the guidelines for operations in the field of functional neurosurgery, they contributed to intensified "Renaissance" functional neurosurgery.
Material and methods Articles in the EBSCO database were analyzed using the keywords: peripheral nerves, stimulation, electrostimulation, neurosurgery. Furthermore, neural searched betting sites in terms of the technical aspects of this equipment. Available literature was subjectively selected. Then searched the latest version of each article.
Results Offered different tools offered technical specifications. Technological developments have allowed the convenience to use devices, min. by increasing control by the user or representative of the operation of the pacemaker.
Conclusions The development of technology and neuroscience neurostymulatorów resulted in the development of many available on the market. However, more research is needed to determine the exact parameters of stimulation, which would get the largest size stimulation effect while minimizing adverse effects.
Olympic weightlifting movements and their variations are believed to be among the most effective ways to improve power, strength, and speed in athletes. This study investigated the effects of two Olympic weightlifting variations (hang cleans and hang snatches), on power (vertical jump height), strength (1RM back squat), and speed (40-yard sprint) in female collegiate athletes. 23 NCAA Division I female athletes were randomly assigned to either a hang clean group or hang snatch group. Athletes participated in two workout sessions a week for six weeks, performing either hang cleans or hang snatches for five sets of three repetitions with a load of 80-85% 1RM, concurrent with their existing, season-specific, resistance training program. Vertical jump height, 1RM back squat, and 40-yard sprint all had a significant, positive improvement from pre-training to post-training in both groups (p≤0.01). However, when comparing the gain scores between groups, there was no significant difference between the hang clean and hang snatch groups for any of the three dependent variables (i.e., vertical jump height, p=0.46; 1RM back squat, p=0.20; and 40-yard sprint, p=0.46). Short-term training emphasizing hang cleans or hang snatches produced similar improvements in power, strength, and speed in female collegiate athletes. This provides strength and conditioning professionals with two viable programmatic options in athletic-based exercises to improve power, strength, and speed.

Patients with neurodegenerative diseases are required to use cognitive resources while maintaining postural control. The aim of this study was to investigate the effects of a frontal cognitive task on postural control in patients with Alzheimer, Parkinson and controls. Thirty-eight participants were instructed to stand upright on a force platform in two experimental conditions: single and dual task. Participants with Parkinson's disease presented an increase in the coefficient of variation greater than 100% in the dual task as compared to the single task for center of pressure (COP) area and COP path. In addition, patients with Parkinson's and Alzheimer's disease had a higher number of errors during the execution of the cognitive task when compared to the group of elderly without neurodegenerative diseases. The motor cortex, which is engaged in postural control, does not seem to compete with frontal brain regions in the performance of the cognitive task. However, patients with Parkinson's and Alzheimer's disease presented worsened performance in cognitive task.

It has recently been verified using the Nintendo Wii in the health context. The aim of this study was to analyze the acute cardiovascular responses monitored by the behavior of heart rate, systolic blood pressure, diastolic blood pressure and double product in an environment virtually simulated by Nintendo Wii. The sample was consisted of 18 health college students with mean age 22.07 ± 1.34 years. The variables were observed with use of delta analysis (post value – prior value) after 25 basketball shoots in two experimental situations: (I) seating and (II) jumping vertically. The results suggest the physical activity in a virtual environment emulated by Nintendo Wii is able to change the acute cardiovascular responses, mainly when performed in association with vertical jumps. Thus, the results support the feasibility use of the Nintendo Wii in training programs and favor its indication more securely.

O presente estudo foi delineado para avaliar os efeitos imediatos e tardios da restrição protéica durante a vida fetale neonatal sobre a ação periférica da insulina em ratos. Ratas grávidas da linhagem Wistar foram alimentadas,durante a gravidez e a lactação, com dietas isocalóricas hipoprotéica (6% de proteína) e normoprotéica (17% deproteína), servidas à vontade. As crias do sexo masculino foram avaliadas ao desmame (21 dias) e aos 90 dias.A partir daí, todos os animais passaram a receber a dieta normoprotéica. Ao desmame, os animais hipoprotéicosapresentaram peso corporal e teores séricos de glicose e de insulina significativamente menores em relação aosnormoprotéicos. A taxa de remoção de glicose após administração de insulina exógena (Kitt) foi significantemente superior nos animais hipoprotéicos em relação aos normoprotéicos. A captação e oxidação de glicose pelo músculo sóleo isolado estimuladas pela insulina não foram diferentes entre os animais dos dois grupos. Na idade adulta, os teores séricos de glicose, insulina e os valores de Kitt foram semelhantes nos animais de ambos os grupos,assim como a captação e a oxidação de glicose pelo músculo sóleo isolado. Por outro lado, quando submetidosaos estresses de jejum de 48 horas e exercício agudo, os animais hipo/normoprotéicos reduziram a captação eoxidação de glicose, fato este não observado entre os normoprotéicos. Esses resultados sugerem que o metabolismo glicídico dos animais possa estar restabelecido na ausência de fatores estressantes. A incapacidade em responder adequadamente a diferentes estresses pode levar à intolerância à glicose.
