Part 1 Patients with idiopathic Normal Pressure Hydrocephalus (iNPH) have variable disabilities regarding gait, balance, cognition and continence. Analysis of the gait pattern in iNPH has an important part in clinical diagnosing and evaluation of outcome after shunt surgery. The gait pattern is only partly explained and more detailed information about gait in iNPH is needed in relation with ordinary clinical measurements. Part 2 Approximately 70 % of patients with iNPH improve after shunt surgery. Commonly different grading scales and measurements regarding functions are used in the evaluation. To some extent, patients improve in Quality of life after surgery (QoL). In this study, the patient´s own grading of improvements in relation with QoL, sense of coherence (SOC) and symptoms of depression and anxiety are analyzed.
