Article Synopsis
  • This study looked at how physical and occupational therapists treat upper limb paralysis after a stroke and what factors influence their treatment choices.
  • A total of 638 therapists participated, indicating their preferred methods for treating different severity levels: task-specific training for mild cases, repetitive facilitative exercise for moderate, and electrical stimulation for severe.
  • Results showed that strong evidence supporting treatments and patient preferences significantly impacted therapists' decision-making processes.

Article Synopsis
  • * The study involved 203 stroke patients and utilized segmental regression analysis to evaluate the relationship between FMA-Upper Extremity (FMA-UE) scores and MAL Amount of Use (MAL-A) scores, finding an important inflection point at 45.3 points for the FMA-UE.
  • * Results indicated differences in the frequency of upper extremity use post-stroke, highlighting the importance of refining assessments to better capture the functional disparities

Background: Transcranial direct current stimulation, a therapeutic modality to modulate the excitability of injured and uninjured brain hemispheres in stroke patients, is expected to be effective in treating upper limb paralysis. We describe the use of transcranial direct current stimulation to improve the function and frequency of use of the paralyzed hand of a patient with lenticulostriate artery occlusion.

Case Presentation: A Japanese man in his fifties developed a left internal hindfoot perforator branch infarction owing to lenticulostriate artery occlusion, and presented with severe right upper and lower limb paralysis.

Background:  In order to establish an effective screening method for respiratory inhibition after crying (RIAC), we prospectively studied the correlations between infant RIAC and perinatal factors.

Methods: We monitored infants (n=141) born from May through July 2009 with polygraphy and evaluated the presence of RIAC and respiratory pause that occurred when feeding was initiated immediately after crying with a decrease in oxygen saturation (SpO(2) ) to <60%. The infants were screened for increased echogenicity, a cyst in the ganglionic eminence (GE), or a subependymal cyst by cranial ultrasound.

Background: The QOL questionnaire version 2001 for pediatric patients with bronchial asthma and their parents or caregivers includes 15 questions for patients under the age of 4 years and 20 questions for patients over the age of 4 years. We have already reported that the QOL questionnaire version 2001 reflects reliability (including reproducibility), factorial validity, and changes in paroxysmal attacks of asthma. In this study, we revised the questionnaire for use in routine medical practice.
