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 patients own grading of improvements in relation with QoL, sense of coherence (SOC) and symptoms of depression and anxiety are analyzed.


Consecutive patients with iNPH, which are planed for shunt surgery at the neurological and neurosurgical departments of University Hospital of Linkping, are included. Before operation and 3 months postoperatively, the patients gait pattern are analyzed with RehaGait analysis system. The patients also fill in a questionnaire about SOC, QoL and symptoms of depression and anxiety at these assessment sessions. Additionally at the follow up, the patients are grading their overall experienced change and specified changes in gait, balance, continence and neuropsychology with the global Rating of Change Scale (GRC-scale). At baseline and at follow up, the patients also perform the ordinary clinical assessments with measurements covering the domains gait, balance, continence and neuropsychology in the iNPH-scale. A convenience sample of Healthy individuals aged > 60 years, conduct the same questionnaires: SOC, QoL and symptoms of depression and anxiety and perform the RehaGait analysis system once.
