1. Short-Term Effects of a Resistance Training Program Using Elastic Tubing in Patients with Heart Disease
Abstract Background Resistance training is effective in cardiac rehabilitation; however, it is conventionally performed using free weights or machines, which can pose logistic challenges to patients with restricted mobility. For its ease of access and cost-effectiveness, elastic tubing is a particularly appealing alternative, but it remains underutilized fo

2. Verbal instruction does not change myoelectric activity during seated row exercise in trained and untrained men
Abstract Aims: This study aimed to analyze the effect of verbal instruction on myoelectric activity (EMG) of the elbow flexors and shoulder extensors muscles during seated row exercise at 70%1RM, in trained and untrained individuals. Methods: The study sample comprised of seven males (21 ± 1.9 years) who had not practiced resistance training for at least

3. Can the positions of the spastic upper limb in stroke survivors help muscle choice for botulinum toxin injections?
RESUMO As deficiências motoras que ocorrem nos indivíduos com doença cerebrovascular (DCV) são prevalentes e contribuem para dependência, dor e incapacidade, o que pode atrasar a reabilitação do membro superior e sua funcionalidade. O tratamento com toxina botulínica do tipo A (BoNT-A) é indicado para a espasticidade focal e requer conhecimento da b

4. Acute effects of maximal isometric muscle action of the elbow extensors on contralateral dynamic task of the elbow flexors: a pilot study
ABSTRACT Aim the aim was to investigate the influence of a maximal isometric muscle action of the elbow extensors on the contralateral dynamic task of the elbow flexors. Methods Seventeen recreationally trained men (23.3 ± 4.9 yrs, BMI: 24.8 ± 2.2 Kg/m²) underwent two randomized different testing sessions separated by one week. In the control session (C

5. Estudo da fadiga dos músculos flexores do cotovelo e dos dígitos em contratação isométrica
O objetivo deste estudo foi analisar simultaneamente o comportamento de alguns músculos flexores e extensores do cotovelo durante fadiga isométrica do Bíceps Braquial. Foram coletados os EMG dos músculos Bíceps Braquial (BBL), Braquiorradial (BRD), Flexores Superficiais dos Dedos (FSD), Tríceps Braquial (TBL) e Extensores Comuns dos Dedos (ECD). Simult

6. Reciprocal inhibition between wrist flexors and extensors in man: a new set of interneurones?
1. Interneurones mediating reciprocal inhibition between wrist flexors and extensors in man are characterized using both Renshaw cells and transarticular group I afferent activation. 2. Renshaw cells were activated by reflex discharges evoked by a tendon tap. The tendon tap was applied to the tendon of the muscles from which the Ia fibres responsible for the

7. Voluntary muscle strength in hemiparesis: distribution of weakness at the elbow.
Maximal voluntary strength (torque) of the flexors and extensors of the elbow was measured in 56 normal subjects and 18 hemiparetic subjects. In normal subjects the ratio of extension to flexion strength averaged 55% and did not differ significantly between sides or sexes. The ratio of maximal extensor to flexor strength on the clinically unaffected side of

8. Pattern of cutaneous inhibition of the propriospinal-like excitation to human upper limb motoneurones.
1. The pattern of cutaneous inhibition of non-monosynaptic excitation (or 'propriospinal-like' excitation) to various species of motoneurones-wrist flexors and extensors, biceps and deltoid - was investigated in man. 2. Changes in the firing probability of individual voluntarily activated motor units were studied following various stimuli. The effects of wea

9. Pathological stretch reflexes on the "good" side of hemiparetic patients.
The reflex EMG responses from a tendon tap or an imposed, medium amplitude (30 degrees), stretch at a range of stretch velocities have been recorded from the triceps and biceps muscles of normal human subjects and in both the affected and "unaffected" arms of hemiparetic patients under relaxed conditions. In the hemiparetic arm, exaggerated tendon jerks were

10. Task-dependent changes in gain of the reflex response to imperceptible perturbations of joint position in man.
1. It has been demonstrated recently that, when suitably instructed, subjects could alter the stiffness at the elbow in response to a slowly and imperceptibly changing elastic load. Although evidence was provided in favour of this occurring via changes in gain of the reflex response to stretch, changes in the degree of co-contraction could not be entirely ru

11. Reciprocal Ia inhibition between elbow flexors and extensors in the human.
1. Reciprocal inhibition between elbow flexor and extensor muscles (biceps and triceps brachii) has been investigated in nine healthy subjects. Two techniques were used to assess changes in motoneurone excitability after stimulation of antagonist muscle afferents: (1) monosynaptic reflexes elicited by a mechanical stimulation of the distal muscle tendon (ten

12. Electromyographic responses evoked in muscles of the forelimb by intracortical stimulation in the cat.
Chronically implanted microwires were used to deliver brief trains of electrical stimuli (11 cathodal pulses at 330 Hz and intensity 5-35 microA) to sixty-two locations in the grey matter of the pericruciate cortex in cats. Electromyographic (e.m.g.) responses in the contralateral forelimb were recorded from a total of ten muscles (four to eight in each anim
