Values are given as Mean (SD) or frequency. Gait performance is registered as 1–6: 1 = normal; 2 = insecure; 3 = insecure cane; 4 = bimanual support; 5 = aided; 6 = wheelchair. 1–4: 1 = none; 2 = slight; 3 = moderate; 4 = severe. IW = Impairment of wakefulness (1 = none; 2 = slight; 3 = moderate; 4 = severe). MoD = mean of differences which is a measure of overall improvement (see statistics). Significant differences between SNPH and INPH patients preoperatively are indicated in the Preop INPH column. Differences between the pre- and postoperative assessment were analysed for SNPH and INPH patients as indicated in the Postop columns. ns = non significant; * = p ≤ 0.05; ** = p ≤ 0.01; *** = p ≤ 0.001. | |||||
