BACKGROUND: Various exercises have been proposed to mitigate chronic low back pain (LBP). However, to date, no one particular exercise has been shown to be superior. Hence, the aim of this study was to compare the efficiency between 2 exercises: the individualized graded lumbar stabilization exercise (IGLSE) and walking exercise (WE). METHODS: A randomized controlled trial was conducted in 48 participants with chronic LBP. After screening, participants were randomized to 1 of 4 groups: flexibili

Voice analysis is a safe, noninvasive, and reliable screening tool for patients with dysphagia and can detect patients at high risk of clinically significant aspiration, thereby augmenting clinical bedside examination.

The prevalence of spasticity in stroke patients transferred to our Department of Rehabilitation Medicine was 42.4%. NIHSS scores, nonoperative treatment, and low Motricity Index scores were significantly predictive of spasticity. A nonspastic group showed greater functional improvement during rehabilitation.

The pharyngeal phase of swallowing is a complex event consisted with subsequent muscular contractions and pressure gen-eration to move a bolus from the mouth to the esophagus. Recently, high-resolution impedance manometry (HRIM) was devel-oped and used for the evaluation of pharyngeal dysphagia. Although HRIM provides precise pharyngeal pressure information, it has yet to be used as part of routine clinical practice for the assessment of dysphagia. The main reasons are thought to be that the tes

Abstract There have been many studies on adolescent idiopathic scoliosis related abnormal muscle contractions of the spine. However, previous studies using surface electromyography to investigate paraspinal muscle asymmetry are controversial, lacking in clarity of results, and hindered by methodological limitations. The purpose of this study was to investigate the relationship between imbalance factors including surface electromyography activity according to the scoliosis curve type and leg leng

BACKGROUND: Lumbar stabilization exercises are effective for the treatment of patients with low back pain. However, personalized exercise programs are required to facilitate more efficient treatment, as each individual exhibits the different characteristics of the trunk muscles and pain. OBJECTIVE: To determine the effects of graded lumbar stabilization exercises on the trunk muscles in healthy individuals, using surface electromyography. DESIGN: A cross-sectional prospective study. SETTING: Out

Age-related weakness due to atrophy and fatty infiltration in oropharyngeal muscles may be related to dysphagia in older adults. However, little is known about changes in the oropharyngeal muscle activation pattern in older adults. This was a prospective and experimental study. Forty healthy participants (20 older [> 60 years] and 20 young [< 60 years] adults) were enrolled. Six channel surface electrodes were placed over the bilateral suprahyoid (SH), bilateral retrohyoid (RH), thyrohyoid (TH),

The bolus volume was shown to have significant effect on pharyngeal pressure and timing, but the texture did not show any effect on pharyngeal swallowing. The parameters of HRM were more sensitive than those of kinematic analysis. As the parameters of HRM are based on precise anatomic structure and the kinematic analysis reflects the actions of multiple anatomic structures, HRM and VFSS should be used according to their purposes.

In summary, the phenotype of neuropathic pain was associated with the efficacy of different pharmacologic treatments. Symptom-based treatment, therefore, can lead to more efficient analgesia.
