Stimulation frequency and pulse width will be uniformly held constant at 60 Hz and pulse width at 450 ms. The perception and discomfort amplitude will be defined by increasing the stimulation amplitude in steps of 0.1 V. The amplitude at which the patient starts feeling paraesthesis is called the perception threshold. The threshold at which the patient does not want the voltage to be increased any further because of painful sensations is designated the discomfort threshold. 100% stimulation is defined as stimulation at 90% of the range between perception and discomfort thresholds.

30% stimulation means a stimulation level at 30% of the range between perception threshold and 100% stimulation level

Occipital Nerve Stimulation in Medically Intractable Chronic Cluster Headache

An attack is defined as any attack recognised by the patient as being a CH attack. So also the attacks treated with oxygen or triptans.

The investigators will ask the patient whether he/she would recommend the treatment to another patient using a 5 point (Likert) scale: Strongly disagree, disagree, neither agree nor disagree, agree, strongly agree.

It is also investigated whether predictive factors can be identified with respect to the outcome in a hypothesis generating manner. We will look at the body mass index (BMI) and assess the predictive value of response after 5-7 days.

All and treatment-related adverse events will be documented by the investigators.

MAF: We will repeat the primary analysis, with the MAF as outcome instead of the logarithm of the MAF.
