Article Synopsis
- Non-invasive neuromodulation, particularly transcranial focused ultrasound (FUS), holds potential for brain interventions but requires further understanding of its effects.
- The study involved 22 healthy volunteers to explore the temporal dynamics of FUS, comparing brain activity before and after stimulation in two different brain areas: the right inferior frontal cortex and the right thalamus.
- Results showed that FUS effects are time-sensitive and connected to brain areas related to the stimulation, with notable behavioral changes linked to the right inferior frontal cortex, influenced by the acoustic pressure applied during FUS.
Article Synopsis
- Low-frequency transcranial ultrasound stimulation (TUS) can influence brain function with high precision and deep target reach, but the duration and dynamics of its effects are not well understood.* -
- In a study with three monkeys, TUS was applied to specific brain areas, and resting-state fMRI scans were conducted to analyze changes in brain connectivity over time and between individuals.* -
- The findings revealed that TUS leads to varied functional connectivity changes, with six distinct time-courses of effects identified, and emphasized the importance of tracking brain changes over time and considering individual differences in responses to TUS.*
Purpose: As most of the cases of avascular necrosis (AVN) in Saudi Arabia is seen in young population and as literature showed good effect of extracorporeal shock wave therapy (ESWT) in reducing pain and oedema in avascular necrosis and delaying the need of surgical intervention. Our purpose of this study is to assess the effectiveness of ESWT in reducing pain, improving range of motion (ROM) and delaying the surgical intervention in patient with AVN of femoral head and compare our results to published literature.
Material And Methods: We have treated 24 patients, 13 males and 11 females with a mean age of 29 years (range 14-48) with 34 hips affected.
