Can fatigue predict walking capacity of patients with Parkinson's disease?

Unlabelled: Although fatigue is an expressive symptom of Parkinson's disease (PD), few studies have investigated the association between fatigue, mobility and walking capacity of these patients.

Objective: To investigate whether fatigue is an independent factor associated with mobility and the walking capacity in patients with PD.

Methods: Forty-eight patients with PD (22 with fatigue) were tested for mobility and their walking capacity: Timed Up and Go (TUG), 10-Meter Walk Test (10MWT) at usual and fastest speed, and 6-Minute Walk Test (6MWT).
