Abstract Background Ankle sprain is the most common lower limb injury in physically active individuals. Loss of function, decreased postural control (PC), strength deficit, and reduced range motion (ROM) are after acute lateral ankle sprains. Some patients experienced long lasting symptoms, with recurrent sprains, episodes giving-way: a condition known as chronic instability (CAI). Evaluating function CAI clinical environment important to identify severity condition, addition allowing assess...

Achilles tendinopathy (AT) is one of the most frequent overuse injuries in ankle. The evidence base for its conservative management AT continues to evolve, but there still a gap efficacy any modality treatment high-quality studies. This systematic review and meta-analysis investigated EE improving pain function adult patients with mid-portion compared other forms exercise. A search was performed PubMed, BIREME, SportDiscus, Cinahl, Web Science PEDro, November 2022. methodological quality...

Infiltration of surgical wounds with long‐acting local anaesthetics (LA) is used to reduce postoperative incisional pain. We hypothesised that infiltration LA interferes wound healing in rats. Seventy‐two rats were allocated into nine groups. After intraperitoneal anaesthesia, the interscapular dorsal region was infiltrated equivolumes saline, 0·5% bupivacaine or ropivacaine, a randomised double‐blind fashion. A standardised incision performed area and sutured closed. The euthanised on 3rd...

We assessed and compared the effects of swimming, jumping, vibration therapies on prevention bone loss because unloading. Eighty W istar rats were randomly divided into eight groups: S , permanent hind limb‐suspended rats; CON control + wim, unloading interrupted by swimming exercise; C Swim suspension regular weight‐bearing with same duration as in wim protocol; J ump, jumping Jump for group; V ibr, vibration; Vibr interruptions protocol that used ibr rats. At end experiment, mineral...

The aim of this study was to compare the effect standing frame and electrical stimulation on bone quality in a rodent transection model spinal cord injury (SCI).Seven-week-old male Wistar rats were divided into four groups: sham, n = 10; SCI, 7; SCI + frame, stimulation, 7. Complete generated by surgical at T10 level. Therapies initiated 3 days after surgery, days/wk, 20 mins/day, for 30 days. Animals killed day 33 postinjury.No treatment preserved mineral density any skeletal site tested (P...

Background: Unstable distal femoral fractures in children are challenging lesions with restricted surgical options for adequate stabilization. Elastic nails have become popular treating shaft fractures, yet they still using fractures. The aim of this study was to test whether end caps (CAP) inserted into the nail extremity improved mechanical stabilization a segmental defect at metaphyseal-diaphyseal junction created an artificial pediatric bone model. Methods: Two 3.5-mm titanium elastic...

Transcutaneous electrical nerve stimulation (TENS), manual acupuncture (MA), and spinal cord (SCS) are used to treat a variety of pain conditions. These non-pharmacological treatments often thought work through similar mechanisms, thus should have effects for different types pain. However, it is unclear if each these equally well on type condition. The purpose this study was compared the TENS, MA, SCS neuropathic, inflammatory, non-inflammatory models.TENS 60 Hz, 200 μs, 90% motor threshold...

Rat tail suspension is an accepted method to create experimental osteopenia. However, periods longer than 3 wk may cause skin sloughing or rat slippage. The hypothesis was that a traction system with skeletal anchorage through one vertebra would prolong the time without significant complications.There were 80 young adult female Wistar rats submitted of following interventions: (N = 20), no intervention and baseline control 20). All animals followed up either for 10) 6 wk. Animals assessed...

High intensity functional training (HIFT), usually called CrossFit, is a physical that has gained much popularity in the past few years. The risk of acute and overuse injuries HIFT unclear. This study evaluated incidence HIFT, characterizing severity, location, associated factors.This cross-sectional was conducted between January May 2021. practitioners were recruited through social media answered an online questionnaire on characteristics injury history.A total 606 subjects (264 male 342...

The shoulder joint is the most commonly injured in CrossFit practitioners, because of high intensity and loads associated with this sport. Despite large number clinical cases, there a shortage studies that investigate influence biomechanical aspects upper limbs' injuries on practitioners. This study hypothesized would be difference function, strength, muscle activation between Crossfit practitioners without pain.We divided 79 into two groups according to whether they reported pain (n = 29)...

To mechanically and histologically evaluate the application of low-level laser therapy to reparative process on lesions caused by impact gastrocnemius muscles rats.45 female Wistar rats were divided into three groups (n=15/ group): C (control, no lesion), ML (muscle lesion) ML-L lesion therapy). The experimental muscle was produced letting a 250 g load drop from height 30 cm, directly onto muscle. animals in group subjected 960 nm laser, 2 J/cm(2), site, for days, twice day. Mechanical tests...

OBJETIVO: Avaliar, mecânica e histologicamente, a aplicação do laser terapêutico de baixa potência, no processo reparativo lesões provocadas por impacto em músculos gastrocnêmios ratas. MÉTODOS: 45 ratas Wistar foram divididas três grupos (n=15/grupo): C (controle, sem lesão), LM (lesão muscular) LM-L muscular laserterapia). A lesão experimental foi produzida pela queda uma carga 250 g, altura 30cm, diretamente sobre o músculo. Os animais grupo submetidos à 960nm, 2J/cm², durante dias, duas...

OBJETIVO: Avaliamos a influência do diâmetro e modo de preparação orifício piloto na resistência ao arrancamento no torque inserção dos parafusos pediculares com interno cônico. MÉTODOS: Ensaios mecânicos foram realizados alma cônica 4,2mm 5,2mm inseridos nos pedículos vertebrais lombares suínos. O foi confeccionado broca sondas (pontiaguda cortante) diferentes diâmetros. RESULTADOS: Testando o parafuso perfuração igual ou inferior menor parafuso, aumentou arrancamento. Perfurações...

OBJETIVO: Realizar um estudo biomecânico de quatro técnicas fixação das fraturas em partes da cabeça umeral. MÉTODOS: A fratura foi reproduzida 40 úmeros plásticos, divididos grupos dez conforme a técnica fixação, cada uma delas empregando diferentes recursos configurações distintas. Os modelos umerais foram montados escápula alumínio, com tiras couro mimetizando os tendões do capuz rotador, e submetidos ensaios encurvamento torção máquina universal ensaios, usando rigidez relativa como...

INTRODUÇÃO: A realização de atividade física garante benefícios ao tecido ósseo uma vez que o estresse provocado pelo carregamento promove adaptações positivas em suas propriedades mecânicas, sendo sua utilização estratégia não farmacológica para fortalecimento ósseo. OBJETIVO: investigar efeito protocolos treinamento alto impacto com frequências semanais e períodos diferentes nas mecânicas ossos ratas Wistar. MÉTODOS: Foram utilizadas 54 Wistar, idade média 10 semanas, divididas seis grupos...
