The active-knee-extension test (AKE) and the straight-leg-raise (SLR) are widely used for flexibility assessment. A number of investigations have tested reliability these measures, especially AKE. However, in most studies, sample involved subjects with normal flexibility. In addition, few studies determined standard error measurement (SEM) minimal detectable difference (MDD), which can provide complementary more clinically relevant information than intraclass correlation coefficient (ICC)...

It has been found that fractal-like patterns are present in the temporal structure of variability healthy biological rhythms, while pathology and disease lead to their deterioration. Interestingly, it recently suggested these rhythms related with each other, reflecting overall health or lack it, due interaction. However, underlying neurophysiological mechanisms responsible for such dependency remain unknown. In addition, this relationship between different elements needs be first verified...

The adoption of incorrect postures or carrying overweight backpacks may contribute to the development musculoskeletal disorders in school children.This study evaluated weight and postural habits adopted schools by Portuguese adolescents, their association with scoliosis low back pain (LBP).The sample comprised 966 students, aged between 10 16 years. instruments included a questionnaire characterize presence LBP weighing scoliometer evaluate scoliosis.No was observed assuming backpacks,...

SummaryIntroduction:overweight and obesity in adolescents are major public health problems with particular interest, because of their potential association risk factors for development diseases. The study aimed to determine the prevalence overweight southern Portugal investigate cardiovascular, respiratory musculoskeletal diseases.Methods:the sample consisted 966 aged 10 16 years. calculation body mass index (BMI), evaluation blood glucose, total cholesterol triglycerides, pressure,...

Cervical pain has been linked to increased motor unit activity, potentially associated with the initiation and progression of chronic neck pain. Therefore, this study aimed compare time-course changes in cervical superficial muscle activation patterns among dental students without throughout their initial semester clinical training. We used an online Nordic Musculoskeletal Questionnaire for group allocation between (NP) (n = 21) control (CG) 23). Surface electromyography (sEMG)...

The importance of 24-h movement behaviour, including sleep, physical activity (PA) and sedentary behaviour (SB), has gained prominence due to its significant impact on the health development children, those with cerebral palsy (CP). checklist for CP, a tool developed in Netherlands monitor CP paediatric population, requires translation cultural adaptation Portuguese use Brazil Portugal. This cross-sectional methodological study involved translating culturally adapting into Brazilian (BP)...

This study analyzes the immediate effects of wearing a Therasuit on sagittal plane lower limb angular displacements during gait in children with unilateral spastic cerebral palsy (US-CP). Seven participants (median age = 7.00 years; ranging from 5.83 to 9.00 years) US-CP, levels I and II Gross Motor Function Classification System, were assessed kinematic analysis three different conditions: (A) Baseline; (B) without elastics (C) elastics. Significant improvements observed at hip joint both...

In the last decade, clinical reasoning in physical therapy has been to develop systems for physiotherapists make decisions rapidly, effectively and efficiently, response increasingly complex needs of health rehabilitation units [1]–[3]. Some studies show importance walking aids during from some diseases, after surgery arthroplasty elderly population [4], patients with balance disorders, muscle weakness [5] or people diabetes mellitus [6]. Walkers are important devices that aid process. The...

This study aimed to compare the impact of two Back School Postural Education Programs on improving ergonomic knowledge postures adopted at school and home, as well reducing low back pain (LPB) in adolescents. The sample was constituted by 153 students, aged 10-16 years, with 96 (62.7%) girls, divided into 2 intervention groups (GA, GB). Two tests (theoretical practical) LBP questionnaire were applied 1 week before year after end program. In GA, three sessions performed for each class...

Young people tend to spend most of their time in activities involving inappropriate positions, which can promote musculoskeletal alterations and disorders.To investigate the prevalence low back pain (LBP) young analyse its associations with daily postural habits.Cross-sectional retrospective study evaluating 679 Brazilian (15 18 years old), using questionnaires about LBP awareness habits. The values were calculated for present moment, last three months throughout life. Mann-Whitney U test...

Neck pain can induce specific motor responses and alterations in muscle strength. Therefore, this study aimed to investigate compare the progression of cervical strength within between students with without neck over course their first semester clinical training. We used an online Nordic Musculoskeletal Questionnaire for group allocation, flexion, extension, lateral flexion on both sides was measured using KForce Bubble Pro hand-held dynamometer. Forty-four were divided into (n = 21)...

This article presents a serious game framework developed using Unity 3D engine and Kinect V2 sensor as natural user interface. The games are used for objective evaluation of physical rehabilitation considering the sensors motion detection different body joints training provide types data, such angles velocities, physiotherapists patients during process. data storage capability in remote database thus patient's biometric patients' medical record, obtained scores based values metrics distance...

Objectives The purpose of this study was to determine whether sciatic nerve stiffness is altered in people with chronic low back–related leg pain by using shear wave elastography. Methods In cross‐sectional study, the velocity (ie, an index stiffness) measured both legs 16 participants (8 unilateral and 8 healthy controls). Sciatic during a passive ankle dorsiflexion motion performed at 2°/s isokinetic dynamometer. range torque, as well muscle activity, were also measured. Results pain,...

Surfers are subjected to external factors (ocean currents, wind orientation, wave size, contact with the board and other surfers) that require quick efficient adaptations, increasing risk of injury while riding waves. This study aimed determine incidence injuries over a 12-month period in Portuguese surfers analyze associated factors.The sample included 1016 surfers, aged between 8 64 years; 853 (84%) were male. A questionnaire was administered during stages Regional Circuit Surf...

Abstract This study examined whether a knee flexor isometric contraction at 20% of maximal voluntary until exhaustion would alter the biceps femoris long head (BFlh) and semitendinosus (ST) active stiffness, assessed using ultrasound-based shear wave elastography. Twelve healthy individuals participated in 2 sessions separated by 7 days. Time to was similar both (day 1: 443.8 ± 192.5 s; day 2: 474.6 131.7 p = 0.323). At start fatigue task, ST showed greater stiffness than BFlh (p <...

Chronic ankle instability (CAI) is characterized by the occurrence of repetitive inversion mechanism ankle, resulting in numerous sprains. CAI occurs approximately 70% patients with a history lateral sprain. Many causes functional have been postulated and include deficits proprioception, impaired neuromuscular-firing patterns, disturbed balance postural control.The purpose this study was to compare control behaviour subjects chronic healthy subjects, using traditional linear nonlinear...
