56 Chapter 4 the 34 participants; however, none of these falls occurred during the training itself. Lastly, during the five-week waiting-list period, a total of ten falls (range 1-3 falls per participant) were reported among 7 out of 18 participants. Participant characteristics and co-interventions The participants randomized to either the gait-adaptability training group or waitinglist control group did not differ in demographic or clinical characteristics (Table 1). A total of 16 participants received physical therapy as a co-intervention: in the gaitadaptability training group, 10 of the 18 participants received physical therapy for an average of 70 minutes per week (range 20-270); in the waiting-list control group, 6 of the 18 participants received physical therapy for an average of 100 minutes per week (range 20-180). No other co-interventions were reported. Intervention effects The time required to perform the EFAP obstacle subtask did not decrease more in the gait-adaptability training group compared to the waiting-list control group after adjustment for baseline differences (mean group differences: -0.33 seconds, 95% CI: -1.3;0.6; p=0.471). Similar non-significant results were found for the secondary outcomes, except for the single run of the WALT (mean group differences: -2.14 seconds; 95% CI: -4.1;-0.1; p=0.037, see table 2).
