Frontal Assessment Battery and Falling Related with Freezing of Gait in Parkinson’s Disease

In Japan owing to the recent growth of the elderly population, the number of patients with Parkinson’s disease (PD) is expected to double by 2030 [1]. According to this expectation, the number of patients with PD will increase. Patients with PD are at high risk for falling [2,3], and the risk of fall-related fractures is increasing. Fall-related fractures can lead to serious complications even among patients with good motor ability, and an appreciable number of patients become bedridden or require assistance in daily activities. Thus, “falling” is one of the most disabling features of PD.
