OBJECTIVE: To collate and appraise empirical evidence relating to the effects of
verbal instructions (verbal commands given by another person) on stride length,
gait velocity and stride variability in people with Parkinson's disease. DATA SOURCES: Cinahl, Cochrane, Embase, Medline, PEDro, PsycINFO and Web of Science.
REVIEW METHODS: Independent reviewers extracted data from eligible studies and
assessed methodological quality. The level of evidence was determined by best
evidence synthesis based upon the experimental design, methodological quality and
statistical findings of individual studies. RESULTS: One randomized controlled
study and 12 non-controlled studies fulfilled the selection criteria and involved
149 participants. Five types of verbal instructions were examined which included
'take big steps', 'walk fast', 'swing arms when walking', 'count rhythm when
walking' and 'walk fast with big steps'. Best evidence synthesis found indicative
evidence in support of the use of the instruction to take big steps in walking
training for stride length improvement in people with mild to moderate
Parkinson's disease who are without cognitive impairment. There was insufficient
evidence in support of effects on gait velocity and stride variability. There was
also insufficient evidence in support of effects of other instructions on any of
the gait variables. CONCLUSION: The empirical evidence in support of the benefits
from verbal instructions is weak. The evidence is limited to short-term stride
length improvement from the use of the instruction to take big steps in walking training.
