Background: The aim of this study was to describe the outcome measure timed up and go (TUG) in a large, nationwide cohort of patients with idiopathic normal pressure hydrocephalus (iNPH) pre- and post-operatively. Furthermore, to compare the TUG test to the 10-m walk test (10MWT), the iNPH scale, the modified Rankin scale (mRS) and the Mini Mental State Examination (MMSE), which are commonly applied in clinical assessment of iNPH. Methods. Patients with iNPH (n = 1300), registered in the Swedish Hydrocephalus Quality Registry (SHQR), were included. All data were retrieved from the SHQR except the 10MWT, which was collected from patient medical records. Clinical scales were examined pre- and 3 months post-operatively. Data were dichotomised by sex, age, and preoperative TUG time. Results: Preoperative TUG values were 19.0 [14.0-26.0] s (median [IQR]) and 23 [18-30] steps. Post-operatively, significant improvements to 14.0 [11.0-20.0] s and 19 [15-25] steps were seen. TUG time and steps were higher in women compared to men (p < 0.001) but there was no sex difference in improvement rate. Worse preoperative TUG and younger age favoured improvement. TUG was highly correlated to the 10MWT, but correlations of post-operative changes were only low to moderate between all scales (r = 0.22-0.61). Conclusions. This study establishes the distribution of TUG in iNPH patients and shows that the test captures important clinical features that improve after surgery independent of sex and in all age groups, confirming the clinical value of the TUG test. TUG performance is associated with performance on the 10MWT pre- and post-operatively. However, the weak correlations in post-operative change to the 10MWT and other established outcome measures indicate an additional value of TUG when assessing the effects of shunt surgery. ; Funding Agencies: Umeå University; Rune and Ulla Amlöv foundation; Edit Jacobson foundation; Hjalmar Svenssons foundation; Swedish government; Swedish county councils; ALF-agreement [ALFGBG 720121]

Background: Rehabilitation in iNPH is suggested to be an important factor to improve patientsfunctions but there are lack of clinical trials evaluating the effect of rehabilitation interventions after shunt surgery in iNPH. The objective of this study was to evaluate the effect of a physical exercise programme and goal attainment for patients with idiopathic normal pressure hydrocephalus (iNPH) after surgery compared to a control group. Methods: This was a dual centre randomised controlled trial with assessor blinding, intention-to-treat (ITT) and per protocol (PP) analysis. Individuals diagnosed with iNPH scheduled to undergo shunt surgery at the Linkoping University Hospital in Linkoping and Sahlgrenska University Hospital in Gothenburg, Sweden were consecutively eligible for inclusion. Inclusion was conducted between January 2016 and June 2018. The patients were randomised 1:1 using sequentially numbered sealed envelopes to receive either written exercise information (control group) or written information and an additional supervised high-intensity, functional exercise programme (HIFE) executed twice weekly over 12 weeks (exercise group). Preoperatively, the patients set individual goals. The primary outcome was change from baseline in the total iNPH scale score at the post-intervention follow-up. Secondary outcomes were goal attainment, and change in the separate scores of gait, balance, neuropsychology and continence and in the total score after 6 months. Results: In total, 127 participants were randomised to the exercise group (n = 62) and to the control group (n=65). In the ITT population (exercise group, n =50; control group, n=59), there were no between-group differences in the primary outcome, but the attrition rate in the exercise group was high. The exercise group improved more than the control group in the balance domain scores after 6 months. Post-intervention, the PP exercise population achieved their set goals to a greater extent than the controls. Conclusions: An additional effect of the 12-week HIFE-programme on the overall improvement according to the iNPH-scale after shunt surgery in iNPH was not shown. This could be due to high attrition rate. However, the longterm effect on balance and higher goal achievement indicate beneficial influences of supervised physical exercise. ; Funding Agencies|Linkoping University; Region Ostergotland; Rune and Ulla Amlov foundation; Edit Jacobson foundation; foundation Hjalmar Svenssons forskningsfond; Swedish government [ALFGBG 720121]; Swedish County Councils, the ALF-agreement [ALFGBG 720121]
