Study type | Interventional |
Patients with lumbar disc herniation suffer from pain and morbidity. Surgical intervention
can be a quick and effective relief, however some individuals experience less favorable
outcome.
This study tries to investigate and test the differences in pain perception and pain
modulation between individuals. Using PET/CT scans the investigators try to visualize pain
perception and -modulation in the CNS. This is subsequently correlated with a battery of pain
tests and the surgical outcome of disc herniation surgery.

Primary | EuroQol-5D 3L | The 3-level version of EQ-5D (EQ-5D-3L) was introduced in 1990 by the EuroQol Group. The EQ-5D-3L descriptive system comprises the following five dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each dimension has 3 levels: no problems, some problems, and extreme problems. The patient is asked to indicate his/her health state by ticking the box next to the most appropriate statement in each of the five dimensions. This decision results into a 1-digit number that expresses the level selected for that dimension. The digits for the five dimensions can be combined into a 5-digit number that describes the patient's health state. The EQ VAS records the patient's self-rated health on a vertical visual analogue scale where the endpoints are labelled 'Best imaginable health state' and 'Worst imaginable health state'. The VAS can be used as a quantitative measure of health outcome that reflects the patient's own judgement. |

Primary | Oswestry Disability Index | The Oswestry Disability Index (also known as the Oswestry Low Back Pain Disability Questionnaire) is an extremely important tool that researchers and disability evaluators use to measure a patient's permanent functional disability. The test is considered the 'gold standard' of low back functional outcome tools. 0% to 20%: minimal disability: The patient can cope with most living activities. 21%-40%: moderate disability: The patient experiences more pain and difficulty with sitting, lifting and standing. Travel and social life are more difficult, and they may be disabled from work. 41%-60%: severe disability: Pain remains the main problem in this group but activities of daily living is affected. These patients require a detailed investigation. 61%-80%: crippled: Back pain impinges on all aspects of the patient's life. 81%-100%: These patients are either bed-bound or exaggerating their symptoms. |
