Functional Independence ≠ Optimal Functional Status: An Exploratory Study Demonstrating the Usefulness of Comprehensive Physiotherapy Assessment for Detecting Hidden Functional Risk

Abstract

Introduction

Functional independence is often considered an indicator of healthy aging; however, it does not always guarantee the absence of physical, emotional, or functional impairments that may compromise the quality of life of older adults. From a physiotherapy perspective, a comprehensive assessment allows for the identification of risk factors that frequently go unnoticed when only traditional functional independence scales are used, thus facilitating early detection and the implementation of preventive strategies.

Objective

To analyze the presence of hidden functional risk in apparently independent older adults through a comprehensive physiotherapy assessment of functional status.

Methodology

An observational, descriptive, and cross-sectional study was conducted with 11 adults over 60 years of age recruited during the practical activities of the Physiotherapy for Older Adults course at the Physiotherapy Clinic of the Universidad del Valle de Puebla, Tehuacán Campus, from February to April 2016. The assessment included standardized instruments such as the Barthel Index, Katz Index, Lawton and Brody Index, FRAIL, Mini Nutritional Assessment, Mini-Mental State Examination, Mini-Cog, and geriatric depression scales. Functional tests such as Time Up and Go (TUG), tandem gait, Dual Task, and Short Physical Performance Battery (SPPB) were also administered. Data were analyzed using descriptive statistics with frequencies and percentages.

Results

90.9% of the participants demonstrated functional independence according to the Barthel Index, and 63.6% showed complete independence according to the Katz Index. However, the comprehensive physiotherapy assessment identified relevant alterations that were not evident using these scales. 90.9% presented functional impairment in instrumental activities of daily living according to Lawton and Brody; 36.4% showed pre-frailty or frailty; 27.3% presented poor physical performance on the SPPB test; and 27.3% reported significant depressive symptoms. Additionally, the functional tests revealed factors associated with decreased mobility, balance impairments, and a potential risk of falls.

Conclusions

The results suggest that functional independence does not always reflect optimal functional status in older adults. Although most participants demonstrated independence in basic activities of daily living, the comprehensive assessment identified risk factors associated with frailty, functional impairment, depressive symptoms, and risk of falls that could be overlooked when the assessment is limited solely to traditional scales.

The findings should be interpreted with caution due to the exploratory nature of the study and the small sample size, which consisted of older adults recruited in a clinical-academic setting during practical activities of the Physiotherapy for Older Adults course. Nevertheless, the results identified clinically relevant trends that support the usefulness of comprehensive physiotherapy assessment for detecting hidden functional risk in apparently independent older adults and reinforce the importance of continuing to promote preventive strategies aimed at healthy aging.
