To quantify the reliability of these gait characteristics of the APDM mobility lab.
Design : For studies of screening and diagnostic tests: criterion standard
Setting : In the Affiliated Suzhou Hospital of Nanjing Medical University.
Participants (or Animals, Specimens, Cadavers) :
31 participants were recruited for this study and they included 15 healthy adults(10females 23±1years), 8 healthy older adults(4females, 65±6years) and 7 patients with PD(3females, 65±8years H-Y:Ⅰ-Ⅱ) who were able to walk continuously for at least 2 minutes without assistance.
Interventions : Interventions: Not applicable
Main Outcome Measure(s) :
The gait of 15 young adults(5males 10females), 8 old adults(5males 3females) and 7 patients with Parkinson Disease(4males 3females) was assessed with 2-minutes-walk test twice for each participant on a 15m walkway each 5 days apart. These tests were operated by one operator. The intra-class correlation coefficient(ICC) of three groups were analyzed.
A total of 43 gait variables were obtained such as gait speed, gait cadence, foot strike angle, step duration and so on. 20 variables of young people, 40 variables of the elderly and 33 variables of the patients with PD had high ICC which ranged from 0.8-0.99. 17 variables of young people , 3 variables of the elderly and 6 variables of the patients with PD had moderate ICC ranged from 0.6-0.8. There were 6 variables of the young people and 4 variables of the patients with PD having fair ICC which was less than 0.6.
The study demonstrated that the APDM mobility lab has a good reliability to evaluate spatial-temporal gait in the elderly and patients with PD.
