Abstract

Objective: To determine which statistical techniques enhance our ability to predict ambulation and transfer ability in people with spina bifida (SB).

Design: Retrospective cohort study SETTING: 35 United States outpatient SB clinic sites PARTICIPANTS: individuals (n=4,589) with SB ages 5-73 (median age =13.59) INTERVENTION: not applicable MAIN OUTCOME MEASURE: ambulation ability, which consisted of the following categories: community ambulators, household ambulators, therapeutic ambulators, and non-ambulators SECONDARY OUTCOME: wheelchair transfer ability, as defined by the ability to transfer in and out of a wheelchair unassisted RESULTS: A Recurrent Neural Network (RNN) utilizing a multilayer perceptron discarded 76 cases during case processing, resulting in 4513 that were run through the RNN. The predictions in the resulting testing dataset were 83.22% accurate. Recall was 93.21% for community ambulators, 10.00% for household ambulators, 23.96% for therapeutic ambulators, and 76.70% for non-ambulators. Precision was 85.34% for community ambulators, 16.05% for household ambulators,16.67% for therapeutic ambulators, and 93.47% for non-ambulators. Total predictions included 68.39% for community ambulators, 2.25% for household ambulators, 3.83% for therapeutic ambulators, and 25.53% for non-ambulators. Correspondingly, the model accurately classified 70% of wheelchair transfers, while correctly identifying 97.3% of those able to transfer unassisted.

Conclusions: RNN models hold promise for prediction of functional outcomes such as ambulation and transfer ability in people with SB, particularly for community and non-ambulators. Compared to previous work utilizing traditional logistic regression approaches which misclassified 16% of cases, the RNN resulted in greater prediction accuracy with fewer than 7% of cases misclassified.

期刊介绍: The Archives of Physical Medicine and Rehabilitation publishes original, peer-reviewed research and clinical reports on important trends and developments in physical medicine and rehabilitation and related fields. This international journal brings researchers and clinicians authoritative information on the therapeutic utilization of physical, behavioral and pharmaceutical agents in providing comprehensive care for individuals with chronic illness and disabilities. Archives began publication in 1920, publishes monthly, and is the official journal of the American Congress of Rehabilitation Medicine. Its papers are cited more often than any other rehabilitation journal.
