OBJECTIVE To examine the effectiveness of task-oriented progressive resistance strength training on lower extremity strength and functional performance in chronic stroke subjects. DESIGN Single-blind, randomized controlled trial. SETTING Medical centre and district hospital. SUBJECTS Forty-eight subjects at least one year post stroke. INTERVENTIONS(More)
The relationship of plantar skin temperature to diabetic neuropathy was studied using clinical, nerve conduction and autonomic evaluations. The sympathetic skin response (SSR) was found present in both feet of 25 control subjects and 29 (out of 69) diabetic patients (SSR+ group). For those diabetic patients absent with the SSR in both feet, 18 patients(More)
The aim of the study was to investigate if an abnormal brain response to pain exists in patients with myofascial pain syndrome (MPS) when stimulated in a hypersensitive myofascial trigger point (MTP). Event-related functional magnetic resonance imaging was used to characterize the brain response to pain evoked from an MTP. Activation patterns from patients(More)
OBJECTIVES To evaluate the therapeutic effect of extracorporeal shock wave therapy (ESWT) in shoulders with chronic calcific tendinitis, to compare the functional outcomes of ESWT and transcutaneous electric nerve stimulation (TENS) therapy, and to investigate which types of calcium deposit effectively respond to ESWT. DESIGN Randomized controlled trial.(More)
OBJECTIVES Low-intensity low-frequency electrostimulation delivered within a myofascial trigger point (MTP) has been used as intervention to deactivate MTPs. The therapeutic effect has been suggested to be due to peripheral mechanisms. However, nonpainful stimuli are also known to reduce simultaneous pain through central effects. The primary objective of(More)
OBJECTIVE To systematically review evidence of the accuracy of the procalcitonin test for diagnosis of bacterial infection in patients with autoimmune disease. METHODS The major databases Medline, EMBase, and the Cochrane Library were searched for studies published between January 1966 and October 2011 that evaluated procalcitonin, alone or in comparison(More)
OBJECTIVE To quantitatively evaluate the difference of posture control in sitting position between children with spastic cerebral palsy and normal subjects. DESIGN Twenty children with spastic cerebral palsy who could sit independently and 20 age- and sex-matched normal children were enrolled. The Chatteex Balance System was used to evaluate static and(More)
Impaired cutaneous blood flow and sweating dysfunction might be among the earliest manifestations of diabetic autonomic neuropathy. This study assessed the pathophysiological basis underlying skin vasomotion changes and their relation with progressive sudomotor dysfunction and other autonomic and somatic measures in subclinical diabetic feet.

OBJECTIVES The present study examines functional electric stimulation (FES) applied on patients with hemiplegia of short and long duration for the purpose of upper limb motor recovery and increasing shoulder range of motion. DESIGN Patients with hemiplegia with subluxation participating in the study were placed into a short-duration group or a(More)
