Multicenter Study
Variability of gait speed during six minutes walking test in COPD and cystic fibrosis patients.
Recently, gait speed reached an increasing importance in the management of respiratory patients. The aim of this retrospective study was to compare walking speed and physiological adaptations during the 6MWT in COPD and CF patients. ⋯ Walking speed and cardio-respiratory parameters evolution during 6MWT differ between COPD and CF patients.

Randomized Controlled Trial Multicenter Study
Gait and attentional performance in freezers under methylphenidate.
Attentional resources appear to be involved in the occurrence of FoG. The Parkgait study recently reported that methylphenidate reduces gait hypokinesia and freezing of gait (FoG) in advanced PD patients receiving STN-DBS in the off-dopaminergic drug condition. Methylphenidate is considered to improve attention. The primary objective of the present ancillary study was to determine whether methylphenidate reduced the interference between a cognitive task and gait in patients with FoG. The study's secondary objective was to compare attentional performance in methylphenidate-treated and placebo-treated patients. ⋯ As in the main Parkgait study, methylphenidate did not reduce gait hypokinesia in patients receiving dopaminergic treatment. Our present results suggest that the reduction in the number of FoG episodes previously observed in patients on methylphenidate was neither due to interaction between a dual-task and gait nor an increase in attentional performance.
