Tandem gait (TG) abnormality is common in Parkinson disease (PD), precedes the development of antero-posterior postural instability, is associated with cognitive impairment, and may predict fall risk, according to a recent study. Researchers assessed subjective balance impairment, fall history, antero-posterior postural instability, and TG in PD patients (n=102) (Hoehn and Yahr [HY] stage 0–4). They recorded the age, sex, current medications, HY stage, Schwab and England (S&E) scale score, and Montreal Cognitive Assessment Test (MOCA) score for each patient. Logistic regression was used to evaluate age-adjusted associations between TG and other demographic and clinical factors. They found:
- Of total patient, 63.5% of HY 2 patients and 100% of HY 2.5 and 3 patients had a TG abnormality.
- The presence of TG abnormality was associated with subjective imbalance, falls, freezing of gait, S&E <80, and MOCA score <24 after adjustment for age.
