Deshpande N, Metter EJ, Ferrucci L. Validity of clinically derived Cumulative Somatosensory Impairment Index. Objective: To develop a Cumulative Somatosensory Impairment Index for the lower limbs and evaluate its construct validity for discriminating relevant groups and predictive validity for predicting global postural control over time. Design: Prospective cohort study. Setting: Population-based cohort. Participants: InCHIANTI ("Invecchiare in Chianti" or aging in the Chianti area) study participants (N=960; age, 21-91y, 51.8% women). Interventions: Not applicable. Main Outcome Measures: The Cumulative Somatosensory Impairment Index was derived from baseline performance on clinical tests of pressure sensitivity, vibration sensitivity, proprioception, and graphesthesia. Global postural control was assessed using Frailty and Injuries Cooperative Studies of Intervention Techniques (FICSIT) balance test, time to complete 5 repeated chair stands, and fast walking speed, at baseline and at 3-year follow-up. Results: In participants without neurologic conditions (n=799), the Cumulative Somatosensory Impairment Index was significantly different in age groups classified by decades (P
