Tandem stance ability may be a sensitive test in the onset of gait and balance dysfunction

Development of gait and balance dysfunction is part of the progressive nature of Parkinson’s Disease (PD). Balance dysfunction is often self-reported by individuals only after it has developed. Greater postural sway by individuals with PD has been shown even early in disease progression and thus may be a sensitive measure to detect balance dysfunction prior to onset. Our data shows that the ability to stand tandem is indicative of better gait, mobility, and dynamic and static balance. Assessments that objectively identify individuals at risk for developing gait and balance dysfunction before onset can allow clinicians to intervene earlier to preserve balance.
