Circumstances of falls and fall-related injuries among patients with Parkinson's disease in an outpatient setting

Falls represent continuing, disabling and costly problem in Parkinson's disease (PD). The study was carried out at the Neurology Clinic in Belgrade from August 2011 to December 2012. As many as 180 community dwelling persons with PD aged 22-83 years who sustained a fall in past 6 months were included. Characteristics of the most recent fall were obtained through detailed interviews. Inclusion criteria were: Mini Mental State Examination (MMSE) >= 24, ability to walk independently for at least 10 m and ability to statically stand for at least 90s. Exclusion criteria were: presence of other neurologic as well as psychiatric, visual, audio-vestibular and orthopedic impairments. Falls more frequently took place outside (57.2%) and in the morning (53.9%). As much as 38.9% of persons with PD sustained an injury. Soft-tissue contusion was the most common injury (71.8%) both after indoor and outdoor falls. Fractures accounted for 5% of all fall-related injuries. All the fractures were either arm, clavicle or rib fractures. Tripping was identified as risk factor for outdoor falls (OR = 7.90; 95% confidence interval [95% CI] 3.21-19.39; p = 0.001). In contrast, lower extremity weakness (OR = 0.20; 95% Cl 0.05-0.72; p = 0.015) and internal sense of sudden loss of balance (OR = 0.19; 95% CI 0.05-0.73; p = 0.015) were risk factors for indoor falls. To accomplish long-term results, development of particular prevention programs for persons with PD who fall at home vs. outdoors is recommended. (C) 2014 Elsevier Inc. All rights reserved.
