Development and validation of a physical frailty phenotype index-based model to estimate the frailty index.

Background: The conventional count-based physical frailty phenotype (PFP) dichotomizes its criterion predictors-an approach that creates information loss and depends on the availability of population-derived cut-points. This study proposes an alternative approach to computing the PFP by developing and validating a model that uses PFP components to predict the frailty index (FI) in community-dwelling older adults, without the need for predictor dichotomization.

Methods: A sample of 998 community-dwelling older adults (mean [SD], 68 [7] years) participated in this prospective cohort study.

A Clinician-Free Method Using Top-View Photography for Screening and Monitoring Hallux Valgus.

Background: Hallux valgus is a progressive foot deformity that commonly affects middle-aged women. The aim of this study was to develop a novel method using only top-view photographs to assess hallux valgus severity.

Methods: A top-view digital photograph was taken of each foot of 70 female participants.

Reliability of peak foot pressure in patients with previous diabetic foot ulceration.

Background: Previous reliability studies on peak plantar pressure measurements in patients with previous diabetic foot ulceration (DFU) did not stratify their analyses according to whether the foot had a previous ulcer.

Research Question: Does test-retest reliability of peak foot pressure measurements from the various foot regions differ between the ulcerated and non-ulcerated feet?

Methods: Data from 23 participants with peripheral neuropathy and healed plantar DFU were analysed in this test-retest reliability comparison study. Plantar pressure was evaluated on two sessions using Pedar-X in-shoe system, with a mean of 7.
