Article
Objective To determine the relation between the patient's actual pain, the electromyographer's perception of patient pain, and whether an electromyogram (EMG) is altered. Design Patients undergoing electromyography reported expected pain and p[...]Article
Objective To compare the effects of a vapocoolant spray and an eutectic mixture of local anesthetics (EMLA) cream in reducing pain during needle electromyography examination. Design Randomized controlled trial. Setting Physical medicine and r[...]Article
Objective To assess the diagnostic accuracy of the surface electromyography (sEMG) parameters associated with referred anterior knee pain in diagnosing patellofemoral pain syndrome (PFPS). Design Sensitivity and specificity analysis. Setting [...]Article
Objective To determine the incremental ability of different needle electromyography diagnostic criteria to detect lumbar radiculopathy. Design Blinded cross-sectional study. Setting University hospital. Participants Subjects aged 55 to 80 ye[...]Article
Objective To identify maximum voluntary isometric contraction (MVIC) test positions for the deeper-lying scapulothoracic muscles (ie, levator scapulae, pectoralis minor, rhomboid major), and to provide a standard set of a limited number of test[...]Article
Objective To characterize electromyographic abnormalities according to symptoms (asymptomatic, fatigue, pseudobotulism) reported 1 month after botulinum toxin injection. Design Retrospective, single-center study comparing single-fiber electrom[...]Article
Objective To analyze the ability to discriminate between healthy individuals and individuals with chronic nonspecific low back pain (CNLBP) by measuring the relation between patient-reported outcomes and objective clinical outcome measures of[...]Article
Marcelo Peduzzi de Castro ; Marcelo Peduzzi de Castro ; Heiliane de Brito Fontana ; Marina Costa Fóes ; Gilmar Moraes Santos ; Caroline Ruschel ; Helio Roesler |Background Hip internal and external rotation exercises are usually performed in clinical practice. However, given the synergies required to stabilize the hip in the frontal plane, it is not clear how the activation of target muscles will differ[...]Article
Objective To compare muscle endurance in adolescents with spastic cerebral palsy (CP) with typically developing (TD) peers using a submaximal repetitions-to-fatigue (RTF) protocol. Design Cross sectional. Setting Human motion laboratory. Part[...]Article
Objectives To determine the activation of the gluteus medius in persons with chronic, nonspecific low back pain compared with that in control subjects, and to determine the association of the clinical rating of the single leg stance (SLS) with [...]Article
Slavko Rogan ; Slavko Rogan ; Jan Taeymans ; Beatrice Eggertswyler ; Stefan Zuber ; Patric Eichelberger |Introduction Previous studies have analyzed the effects of manual therapy techniques (MTT) in patients with chronic ankle instability (CAI). Clinicians treat patients according the finding-oriented MTT approach. This approach is seldom pursued i[...]Article
Introduction Stretching and strengthening exercises are commonly used to improve muscle shortness. Consequently, the aim of this trial was to compare the flexion-relaxation response (electromyography activities of shortened hamstring and back mu[...]Article
Objective To investigate whether elastic resistance training can induce comparable levels of muscle activity as conventional machine training in patients with chronic stroke. Design Comparative study. Setting Outpatient rehabilitation facilit[...]Article
Objective To quantify changes in pinch force and brachioradialis (BR) activation after a task-based training program designed to improve pinch force after BR to flexor pollicis longus (FPL) transfer. Design One-group repeated-measures design c[...]Article
Objectives Growing evidence supports hip muscle activation and strengthening exercise prescription to prevent and treat various lower limb injuries. Common prescriptions include single-legged and double-legged squatting, with and without a Sw[...]Article
Objectives To investigate the activity of the thoracic erector spinae muscles and perceived pain intensity immediately after central postero-anterior (PA) mobilisation of the thoracic spine. Design Randomised, placebo-controlled, experimental [...]Article
Alexandre Wesley Carvalho Barbosa ; Fabio Luiz Mendoca Martins ; Debora Fernandes de melo vitorino ; et al. |Objective To evaluate the electrical behaviour of the biceps brachii (BB) and upper rectus abdominis (URA) by surface electromyography (sEMG) during a forearm flexion with and without the Pilates centring technique. Methods Ten female sub[...]Article
Objective To compare responsiveness and predictive ability of clinical and instrumented spasticity assessments after botulinum toxin type A (BTX) treatment combined with casting in the medial hamstrings (MEHs) in children with spastic cerebral [...]Article
Objective To investigate whether lower extremity muscle activation patterns differ in the strides leading to locomotive state transitions in the involved limb of individuals with transtibial amputation. It is hypothesized that all transitions e[...]Article
Background Activity of specific neck muscles is modulated by eye movement. This activity modulation is exaggerated in people with whiplash associated disorders (WAD), but it is unknown whether it is impacted by sitting posture. Objective This st[...]Article
Objective To identify the smallest combinations of maximum voluntary isometric contraction (MVIC) tests that produce near-maximum voluntary activation (MVA) for a large proportion of participants for the shoulder girdle muscles. Design Cross-s[...]Article
Objective To investigate the perception of muscular effort in individuals with multiple sclerosis (MS) and healthy controls during dynamic contractions. Design Case-control study. Setting MS day care center. Participants Individuals with MS [...]Article
Ritchele R. Marchese ; Ritchele R. Marchese ; Alexande Severo do Pinho ; Caroline Mazutti ; Kátia Daniele Rech ; Marcel Grzebellus ; Carsten Schäfer ; Leandro Giacometti da Silva ; Aline de Souza Pagnussat |Introduction This study aimed to evaluate the effectiveness of proprioceptive neuromuscular facilitation (PNF) in promoting muscle irradiation to the lower limbs and to relate these findings with muscle activation during the sit-to-stand task. M[...]Article
Objective To examine the validity and reliability of a sports-specific endurance plank test for the evaluation of global core muscle function. Design Repeated-measures study. Setting Laboratory environment. Participants Twenty-eig[...]Article
Objective To compare the kinematics and muscle activity of subjects with facioscapulohumeral dystrophy (FSHD) and healthy control subjects during the performance of standardized upper extremity tasks. Design Exploratory case-control study. Set[...]
