While a growing number of studies have investigated the effects of
concussion or mild traumatic brain injury (mTBI) on gait, many studies use
different experimental paradigms and outcome measures. The path for translating
experimental studies for objective clinical assessments of gait is unclear.
This review asked 2 questions :
1) is gait abnormal after
concussion/mTBI, and 2) what gait paradigms (single-task,
dual-task, complex
gait) detect abnormalities after concussion. METHODS:
Data sources included
MEDLINE/PubMed, Scopus, Web of Science, and Cumulative Index to Nursing and
Allied Health Literature (CINAHL) accessed on March 14, 2017. Original research
articles reporting gait outcomes in people with concussion or mTBI were included.
Studies of moderate, severe, or unspecified TBI, and studies without a comparator
were excluded. RESULTS: After screening 233 articles, 38 studies were included
and assigned to one or more sections based on the protocol and reported outcomes.
Twenty-six articles reported single-task simple gait outcomes, 24 reported
dual-task simple gait outcomes, 21 reported single-task complex gait outcomes,
and 10 reported dual-task complex gait outcomes. SIGNIFICANCE: Overall, this
review provides evidence for two conclusions: 1) gait is abnormal acutely after
concussion/mTBI but generally resolves over time; and 2) the inconsistency of
findings, small sample sizes, and small number of studies examining homogenous
measures at the same time-period post-concussion highlight the need for
replication across independent populations and investigators. Future research
should concentrate on dual-task and complex gait tasks, as they showed promise
for detecting abnormal locomotor function outside of the acute timeframe.
Additionally, studies should provide detailed demographic and clinical
characteristics to enable more refined comparisons across studies.
