EVALUATION OF ANKLE MOVEMENTS ON A SUDDEN INVERSION PLATFORM
(2023) SANTOS, Leandro Dias dos; PEREIRA, César Augusto Martins; BOLLIGNER NETO, Raul; ALONSO, Angélica Castilho; GREVE, Júlia Maria D'Andrea
ABSTRACT Introduction: Ankle sprains are frequent in sports activities and can lead to joint instability with clinical and performance consequences. Sudden ankle inversion platforms have been used to study the mechanism of ankle sprain. Objectives: To test a static platform that simulates the movement of ankle sprain (sudden inversion) in soccer players. Methods: A platform was developed to perform the sudden movement of an ankle sprain dissociated in three axes: inversion, plantar flexion, and medial rotation. A computer program was also created to read the angular velocity and the time to reach the maximum amplitude of the three axes of movement, synchronized with the platform movements. Thirty soccer players without ankle sprains were evaluated on the sudden inversion platform. Each athlete performed 10 randomly initiated tests, with five per leg. Results: There was no statistical difference in angular velocity or time to reach maximum range of motion of plantar flexion and medial rotation between the tests. During the tests, the angular velocity of the inversion increased. Conclusion: The sudden static platform evaluated the movements performed by the ankle during the sprain reliably in the 10 tests with no difference in the mechanical behavior.

ABSTRACT Introduction: In March 2020, WHO officially decreed that the world was going through a pandemic, that of Covid-19. In May 2022, in Brazil, the end of measures to deal with the pandemic was decreed. In 2022, there was a movement to return to normal care in the provision of care. Objective: In the present study, we carried out a retrospective descriptive analysis of the epidemiological scenario of the ward of the Spine Group at the Hospital das Clínicas of the Faculty of Medicine of the Universidade de São Paulo (HC-FMUSP). Method: Data analysis was performed from information gathered in patients’ medical records. Results: In the analyzed period, there were 152 consultations in hospitalization, with the main cause being spinal trauma. Of all the cases, only 23.68% were scheduled on an elective basis, which despite being a lower than expected number, was shaped by the demands of urgent care channeled to the service in question. Conclusion: Despite a higher number of cases hospitalized in the post-pandemic period, there is still the expectancy of more elective cases to be treated in the future.

(2024) WIND, Aline J. Hakbijl-van der; ROHN, Edward J.; TATE, Denise G.; LEEUWEN, Christel M. C. van; FORCHHEIMER, Martin; STOLWIJK-SWUSTE, Janneke M.; CHARLIFUE, Susan; GREVE, Julia M. D.; NEW, Peter W.; POST, Marcel W. M.
Study designInternational Classification of Functioning, Disability and Health (ICF) linking study.ObjectiveAnalyze cognitive interview data using the ICF as an analytic framework, to examine aspects of social life relevant to quality of life (QoL) according to people with spinal cord injury or disease (SCI/D). This study builds upon results of an international study about the cross-cultural validity of the International SCI QoL Basic Data Set (QoL-BDS).SettingFour specialized outpatient clinics in SCI/D rehabilitation, from the US, Brazil and Australia.MethodsAnalysis of qualitative data from 39 cognitive interviews with SCI/D patients at least one year post onset. Participants were asked to define their concept of QoL, overall life satisfaction, physical health and psychological health, and other relevant matters. Four independent researchers coded text fragments related to the items, and fragments were linked to ICF chapters d6-d9, following established linking rules.ResultsThe proportion of text referring to social life was 35.8% (definition QoL), 24.9% (QoL life as whole), 6.0% (physical health) and 34.9% (psychological health). The most frequent ICF categories were d760 Family relationships, d770 Intimate relationships and d920 Recreation and leisure. Most frequent responded social topics to the 'other issues' item were d770 Intimate relationships, d760 Formal relationships, and d870 Economic self-sufficiency.ConclusionThe importance of social life aspects to the QoL was highlighted based on responses of SCI/D patients, clearly demonstrated through the ICF linking process. Adding a satisfaction with social life item to the QoL-BDS has made this instrument a more comprehensive measure.
Functional and morphological evaluation of the trapezius muscle after spinal accessory nerve transfer to brachial plexus nerves
(2024) SIMAO, Danielle Tiemi; HEISE, Carlos O.; RODRIGUES, Joao C.; YAMAUTI, Lucas S.; VILLEGAS, Robin I.; CHO, Alvaro B.; MATTAR JUNIOR, Rames
IntroductionThe main innervation of the trapezius muscle is provided by the spinal accessory nerve. Several studies describe the contributions of cervical plexus roots to the trapezius muscle innervation, either directly or through connections with the spinal accessory nerve. There is no adequate understanding of how the trapezius muscle is affected after using the spinal accessory nerve in nerve transfer procedures with the usual technique, preserving at least 1 branch for the upper trapezius.MethodsWe evaluated 20 patients with sequelae of traumatic brachial plexus injury who underwent surgical procedures for brachial plexus repair or free muscle transfer, which included the spinal accessory nerve transfer technique and were followed for a minimum of 1 year. The three portions trapezius muscle were evaluated by physical examination, magnetic resonance imaging (analysis of fatty degeneration) and electromyography.ResultsIn all evaluation methods, the middle and lower portions of the trapezius muscle showed more significant morphological and/or functional impairment than the upper portion, in most cases. There was a statistically significant difference in all the complementary exams results, between the affected side (with sacrifice of the nerve) versus the normal side, in the middle and lower portions of the trapezius muscle.ConclusionsPhysical examination alone is not sufficient to determine the residual functionality of the trapezius muscle. Magnetic resonance imaging and electromyography are useful tools to assess both morphological involvement of the trapezius muscle and nerve conduction impairment of the trapezius muscle, respectively. The results suggest that the middle and lower portions of the trapezius muscle are affected by previous SAN transfer and should be considered with caution for further muscle transfer procedures.

(2024) BISNETO, Edgard de Novaes Franca; FERNANDES, Laura Filippini Lorimier; PAULA, Emygdio Jose Leomil de; MATTAR JUNIOR, Rames
Introduction:We present 6 cases of children with atypical cleft hand and discuss a surgical technique. Clinically, participants presented with a lack of pulp-to-pulp pinch due to metacarpophalangeal ligament insufficiency and difficulty grasping large objects because of the narrowed first web.Materials and Methods:Second metacarpal resection and Z-plasty, creating a wide first web. The second extensor digitorum communis tendon was transferred to improve the thumb metacarpophalangeal joint stability.Conclusions:The surgical technique presented in this paper did improve function in oligodactyly or type-IIA atypical cleft hand.
Optimised return to play: high treatment success rate in core muscle injury with surgical release of the anterior tendon of the rectus abdominis muscle and proximal tenotomy of the adductor longus muscle
(2024) PEDRINELLI, Andre; FERNANDAS, Joao Vitor de Castro; LEITE FILHO, Carlos Guilherme Dorile; ALMEIDA, Adriano Marques de; FERNANDES, Tiago Lazzaretti; HERNANDEZ, Arnaldo Jose
Objectives: Core muscle injury is a debilitating condition that causes chronic groin pain in athletes, particularly common in soccer players. The condition is characterised by pain in the inguinal region and can lead to a significant number of absences from high-intensity physical activity. It is caused by repetitive overload without proper counterbalance from the abdominal muscles, hip flexors, and adductors in susceptible athletes. Surgical indications for core muscle injury consider cases where non-surgical treatments have not provided sufficient relief. The aim of this study was to assess the results of surgical intervention for core muscle injury using the technique employed by the Sports Medicine Group of (Institute of Orthopedics and Traumatology of Hospital das Clinicas - Universidade de Sao Paulo). The procedure involves releasing the anterior portion of the tendon of the rectus abdominis muscle near the pubic symphysis, along with proximal tenotomy of the adductor longus muscle tendon. Methods: This study utilised a consecutive historical cohort analysis of the medical records of 45 male athletes, of which, 75.6% were professional soccer players, who underwent surgical treatment between January 1, 2002, and December 31, 2021. The participants included active athletes aged between 18 and 40 years, with a mean age of 23.9 years, and were diagnosed with myotendinous core muscle injury. These athletes experienced pain in the pubic symphysis and adductor tendon region and had previously undergone medical treatment and physical therapy for a duration of three to six months without significant improvement. Results: The average time for athletes to return to sport after surgery was 135 days, with a majority of participants being soccer and futsal players. The surgical intervention yielded promising results, with a positive correlation between unilateral injuries and the time taken to return to sport. The complication rate was low, at 6.7%. Notably, the rate of symptom resolution was high, at 93.3%. Furthermore, the analysis indicated that the player's position on the field significantly influenced the discharge period, suggesting that the game position plays a role in the recovery process. Conclusion: The combined surgical procedure involving the release of the rectus abdominis tendon and adductor longus muscle tenotomy demonstrates favourable outcomes for athletes with core muscle injury. This study provides strong support for the effectiveness of this surgical approach in managing the condition and offers a potential path to recovery and return to sports activities. Study design: Cross-sectional study.

(2023) IAMAGUCHI, Raquel Bernardelli; DIAS, Guilherme Moreira; IWASE, Fernanda Do Carmo; REZENDE, Marcelo Rosa De; JR, Rames Mattar
We observe delayed referrals to appropriate Microsurgery Unit and definitive treatment of traumatic limb amputations. Cases with wrist proximal amputations have a deadline for surgical replantation as these configure life-threatening injuries. Ob-jective: To analyze patients with traumatic proximal wrist upper limb amputations with prolonged ischemic time who underwent temporary artery catheterization to assess stump viability and results. Methods: A case-series study including all patients with a proximal wrist upper limb amputation and a cold ischemic time equal to or above six hours from 2017 to 2021. Results: In total, two surgeons operated eight patients who had experienced forearm amputation injuries. Median ischemia time totaled eight hours. All patients required additional surgeries, most commonly split-thickness skin graft or fixation revision (three patients). This study obtained five successful macroreimplan-tations. The mean cold ischemia time was longer in the group with successful macroreimplantations (7.4 hours) than of the unsuccessful group (9 hours). Conclusion: Macroreplantations require immediate referral to microsurgery and, although tem-porary artery catheterization helps surgical decision making, the technique seems to fail to influence outcomes.

Introduction The COVID-19 pandemic has prompted global research efforts to reduce infection impact, highlighting the potential of cross-disciplinary collaboration to enhance research quality and efficiency.Methods At the FMUSP-HC academic health system, we implemented innovative flow management routines for collecting, organizing and analyzing demographic data, COVID-related data and biological materials from over 4,500 patients with confirmed SARS-CoV-2 infection hospitalized from 2020 to 2022. This strategy was mainly planned in three areas: organizing a database with data from the hospitalizations; setting-up a multidisciplinary taskforce to conduct follow-up assessments after discharge; and organizing a biobank. Additionally, a COVID-19 curated collection was created within the institutional digital library of academic papers to map the research output.Results Over the course of the experience, the possible benefits and challenges of this type of research support approach were identified and discussed, leading to a set of recommended strategies to enhance collaboration within the research institution. Demographic and clinical data from COVID-19 hospitalizations were compiled in a database including adults and a minority of children and adolescents with laboratory confirmed COVID-19, covering 2020-2022, with approximately 350 fields per patient. To date, this database has been used in 16 published studies. Additionally, we assessed 700 adults 6 to 11 months after hospitalization through comprehensive, multidisciplinary in-person evaluations; this database, comprising around 2000 fields per subject, was used in 15 publications. Furthermore, thousands of blood samples collected during the acute phase and follow-up assessments remain stored for future investigations. To date, more than 3,700 aliquots have been used in ongoing research investigating various aspects of COVID-19. Lastly, the mapping of the overall research output revealed that between 2020 and 2022 our academic system produced 1,394 scientific articles on COVID-19.Discussion Research is a crucial component of an effective epidemic response, and the preparation process should include a well-defined plan for organizing and sharing resources. The initiatives described in the present paper were successful in our aim to foster large-scale research in our institution. Although a single model may not be appropriate for all contexts, cross-disciplinary collaboration and open data sharing should make health research systems more efficient to generate the best evidence.
The Influence of Whey Protein on Muscle Strength, Glycemic Control and Functional Tasks in Older Adults with Type 2 Diabetes Mellitus in a Resistance Exercise Program: Randomized and Triple Blind Clinical Trial
(2023) SOARES, A. L. D. S.; MACHADO-LIMA, A.; BRECH, G. C.; GREVE, J. M. D.; SANTOS, J. R. dos; INOJOSSA, T. R.; ROGERO, M. M.; SALLES, J. E. N.; SANTAREM-SOBRINHO, J. M.; DAVIS, C. L.; ALONSO, A. C.
Objectives: To evaluate the effect of whey protein (WP) supplementation associated with resistance training (RT) on glycemic control, functional tasks, muscle strength, and body composition in older adults living with type 2 diabetes mellitus (T2DM). Secondly, to evaluate the safety of the protocol for renal function. Methods: The population comprised twenty-six older men living with T2DM (68.5 ± 11.5 years old). The participants were randomly assigned to the Protein Group (PG) and the Control Group (CG). The handgrip test and evolution of exercise loads, according to the Omni Resistance Exercise Scale, evaluated muscle strength. Functional tasks were assessed by force platform in three different protocols: Sit-to-Stand, Step/Quick Turn, and Step Up/Over. Body composition was evaluated by bioimpedance and glycemic control and renal function were assessed by biochemical analyses. Both groups performed RT for 12 weeks, twice a week, prioritizing large muscle groups. Protein supplementation was 20 g of whey protein isolate and the CG was supplemented with an isocaloric drink, containing 20 g of maltodextrin. Results: There was a significant difference in muscle strength, according to the evolution of the exercise loads, but it was not confirmed in the handgrip test. However, there was no significant difference between the groups, regarding performance in functional tasks, glycemic control, or body composition. Renal function showed no alteration. Conclusion: The intake of 20 g of WP in older male adults living with T2DM did not increase the effect of RT on muscle strength, functional tasks, and glycemic control. The intervention was proven safe regarding renal function.
