OBJECTIVE To compare transverse abdominis (TrA) contractility in stroke patients with hemiparesis and healthy adults using musculoskeletal ultrasonography. METHODS Forty-seven stroke patients with hemiparesis and 25 age-matched healthy control subjects participated in this study. Stroke patients were divided into three groups on the basis of their degree of ambulation. Group A consisted of 9 ...

This study investigated the relationship of lower extremity joint torques and weight-bearing symmetry to sit-to-stand (STS) performance in individuals with chronic stroke. A motion analysis system and two force plates measured STS duration and weight-bearing symmetry (determined by ground reaction forces) during three self-paced and three fast-paced conditions. An isokinetic dynamometer measure...

Stroke patients suffer from gait disturbance due to altered leg muscle actions. Many kinesiological studies have investigated muscle actions, but the metabolic activity of muscles in stroke patients remains to be investigated. We therefore evaluated energy consumption in lower extremity muscles during level walking in hemiparetic individuals. Glucose uptake was measured by positron emission tom...

Abstract Repetitive transcranial magnetic stimulation (rTMS) is commonly dosed using resting motor threshold (rMT), i.e., the minimal stimulator power needed to elicit a response in musculature. Many stroke survivors do not present with rMT, necessitating rTMS dosing during active contractions, or an (aMT). However, relationship between rMT and aMT post-stroke unknown. We conducted cross-sectio...

Lately it has been indicated that the stimulation of both sides of the motor cortices with different frequencies of rTMS can improve the behaviour of a paretic arm. We studied the effect of rTMS in severe cases of post-stroke after nearly 10 years. They had wide hemispheric lesion and their paresis had not changed for more than 5 years. The majority of patients could not move their fingers on t...

BACKGROUND Stroke is the first cause of morbidity all around the world. Entrapment neuropathies are a known complication of stroke. The objective of this study is to assess the frequency of subclinical carpal tunnel syndrome in the healthy and paretic hands of stroke patients. METHODS The authors performed nerve conduction study in the first three days after admission in 39 stroke patients wi...

An experimental lesion in the primary motor or sensory cortices in monkeys leads to functional reorganization in areas surrounding the lesion or in contralateral homologous regions. In humans, task-dependent brain activation after motor stroke seems to be multifocal and bilateral. Although many active structures are seen after stroke, their roles are unclear. For instance, the uninjured primary...

Objectives: Upper limb motor impairment causes limited activities of daily living in stroke survivors. Bimanual therapy is based on Bimanual movement that facilitates cortical balancing by simultaneous movement of paretic and non-paretic arms while performing a task. Studies aimed at exploring the effects of resisted Bimanual therapy with rhythmic auditory cues on arm function, balance, and end...

The relations between surface EMG and isometric force generated by elbow flexor muscles were compared in normal and paretic limbs of 17 hemiparetic human subjects. Similar analyses were performed on both arms of 11 normal subjects. In almost half of the hemiparetic subjects examined (8/17), the slope of the relation between elbow flexion force and surface EMG, measured over the biceps-brachiali...

[Purpose] The purpose of this study was to investigate the effects of the speed of squat exercises on paretic lower extremity muscle activity in patients with hemiplegia following a stroke. [Subjects and Methods] Ten stroke patients performed fast and slow squat exercises for 2 seconds and 8 seconds, respectively. The muscle activities of the paretic and non-paretic sides of the rectus femoris ...
