Abstract
Objective
To investigate whether varying practice context during gait training could reduce
context dependency and facilitate transfer of improved gait performance to a new context.
Design
A single-blind, parallel-group randomized controlled trial.
Setting
Medical university rehabilitation settings.
Participants
Forty-nine participants with Parkinson disease were recruited and randomized into
the constant (CONS) or varied (VARI) context group.
Interventions
All participants received 12 sessions of treadmill and over-ground gait training.
The CONS group was trained in a constant environmental context throughout the study,
whereas the VARI group received training in 2 different contexts in an alternating
order.
Main Outcome Measures
The primary outcome was gait performance, including velocity, cadence, and stride
length. The participants were assessed in the original training context as well as
in a novel context at posttest to determine the influence of changed environmental
context on gait performance.
Results
Though both groups improved significantly after training, the CONS group showed greater
improvement in stride length than the VARI group when assessed in the original practice
context. However, the CONS group showed a decreased velocity and stride length in
the novel context, whereas the VARI group maintained their performance.
Conclusions
Varying practice context could facilitate transfer of improved gait performance to
a novel context.
