The European iNPH Multicentre Study on the predictive values of resistance to CSF outflow and the CSF Tap Test in patients with idiopathic normal pressure hydrocephalus.

Objective: The objective was to determine the sensitivity, specificity, and positive and negative predictive values of the CSF Tap Test (CSF TT) and resistance to CSF outflow (Rout) for the outcome of shunting in a sample of patients with idiopathic normal pressure hydrocephalus (iNPH).

Methods: 115 patients were included in this European multicentre study. Diagnosis was based on clinical symptoms and signs, and MRI changes.

Root compression on MRI compared with clinical findings in patients with recent onset cervical radiculopathy.

Objectives: To evaluate the occurrence of symptomatic and asymptomatic root compression caused by herniated discs and spondylotic foraminal stenosis by MRI in patients with recent onset cervical radiculopathy.

Participants: 78 patients with symptoms and signs of cervical radiculopathy of less than one month's duration.

Methods: The authors determined the clinically suspected level of root compression in each patient.

Cervical collar or physiotherapy versus wait and see policy for recent onset cervical radiculopathy: randomised trial.

Objective: To evaluate the effectiveness of treatment with collar or physiotherapy compared with a wait and see policy in recent onset cervical radiculopathy.

Design: Randomised controlled trial.

Setting: Neurology outpatient clinics in three Dutch hospitals.
