Abstract

Objective: To examine effectiveness of standardized occupational therapy and physical therapy assessments in detecting functional changes and predicting clinical improvement in patients with suspected normal pressure hydrocephalus undergoing cerebrospinal fluid drainage.
Design: Cohort study. Patients: Eighty-seven patients admitted to an inpatient neurology unit for elective cerebrospinal fluid drainage for suspected normal pressure hydrocephalus.
Methods: Before and after a protocol of continuous cerebrospinal fluid drainage via spinal catheter, patients were administered the Functional Independence Measure (FIMTM), Timed Up and Go (TUG), Tinetti Assessment Tool of Gait and Balance, 9-hole peg test, and Cognitive Assessment of Minnesota (CAM). Following cerebrospinal fluid drainage, changes in functional performance were compared for responders to cerebrospinal fluid drainage and non-responders to cerebrospinal fluid drainage.
Results: At baseline, CAM was more sensitive than the Mini Mental State Exam in predicting responders. Post-drainage: responders improved on 52% of tests while non-responders improved on only 11%. Assessments that differentiated magnitude of improvement in responders vs non-responders were: TUG (p<0.05), Tinetti total (p<0.001), Tinetti balance (p<0.001), Tinetti gait (p<0.001), FIM toilet transfer (p<0.001), and FIM lower body dressing (p<0.001).
Conclusion: Specific occupational therapy and physical therapy assessments demonstrate sensitivity to change and predictive value with patients with suspected normal pressure hydrocephalus undergoing cerebrospinal fluid drainage.
