Purpose: To explore the effects of customized 3D-printed assistive technology (AT) on functional performance and feasibility in patients with neurological impairment.
Methods: Patients with neurological impairment were recruited and randomized into customized 3D-printed assistive device group (group 1; = 17) or standard device group (group 2; = 14). The device was designed to assist their writing, spoon using, and typing. Each patient underwent 4-week intervention with the device (30 min per session, twice a week).
Results: We observed significant differences in shoulder abduction ( = .00), external rotation ( = .01), and internal rotation ( = .02) in group 1. And significant differences in abduction ( = .05) and external rotation ( = .05) between the 2 groups. Group 1 achieved significant improvements in writing without AT ( = .04) and with AT ( = .02), spoon use without AT ( = .02) and with AT ( = .03), and hemiplegia-side typing with AT ( = .00). Group 2 achieved significant improvements in writing without AT ( = .01), hemiplegia-side typing without AT ( = .01), and bil-side typing with AT (P = .05). Moreover, no significant differences were noted in other outcome measures.
Conclusions: This study demonstrated that customized 3D-printed AT can improve shoulder active motion for patients with neurological impairment. A positive effect in functional hand tasks after AT intervention. Offering customized AT with specific training could enhance the efficacy of interventions. The feasibility of using 3D printing technology to produce customized AT, which has the potential to be cost-effective and efficient.

Although severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) primarily affects the respiratory system, neurological symptoms were reported both during acute and post-acute COVID-19. Notably, patients with no history of epilepsy or other neurological conditions developed new-onset refractory status epilepticus (NORSE) weeks, months, or even up to a year following the viral infection. While NORSE is uncommon, it carries a high mortality rate and can result in permanent epilepsy.

Introduction: Pneumocephalus and pneumorrhachis are rare postoperative complications, commonly occurring within a few days to months after spinal surgery. They are very rarely reported after thoracic surgeries. This case highlights a unique presentation in the emergency department involving headache and vomiting caused by late complications following thoracic surgery with a titanium rib implant.

Multiple sclerosis (MS) is an autoimmune demyelinating disease of the central nervous system (CNS) that is usually diagnosed between the ages of 20 and 40. Changes in the immune system also observed in cancer may suggest a higher prevalence of cancer in the MS patient population. In recent years, many highly effective immunosuppressive drugs have been introduced into disease-modifying therapy (DMT) which may be associated with a higher risk of cancer development in patients with MS.

Background: Olfactory neuroblastoma (ONB) is a rare sinonasal malignancy primarily treated with surgery. For tumors arising from the olfactory area, traditional treatment involves transcribriform resection of the anterior cranial fossa. Surgery can be performed with unilateral or bilateral resection depending on extent of involvement; however, there are currently no studies comparing outcomes between the two.

Background: Multiple sclerosis is a central neurogenic demyelinating disease. This is one of the most common neurological diseases in humans and is the most debilitating at a young age. Symptoms of multiple sclerosis include vision problems, balance problems, dizziness, sensory disturbances, chronic neuropathy, and fatigue.
