ABSTRACT
BACKGROUND: Sarcopenia, common in the elderly, is characterized by the decline of muscle mass, strength, and physical performance, leading to gait instability and reduced functional independence. However, the biomechanical alterations in gait related to sarcopenia remain poorly understood.
OBJECTIVE: To investigate the relationship between plantar pressure distribution during the stance phase of gait and the suspicion of sarcopenia in elderly women.
METHOD: A descriptive, cross-sectional pilot study was conducted with 19 elderly women residing in southern Minas Gerais, Brazil. Data collected included sociodemographic and clinical variables, SARC-F scores for sarcopenia screening, handgrip strength as a measure of muscle strength, and plantar pressure distribution during gait as an indicator of physical performance.
RESULTS: Participants had a mean age of 75 years, with most being sedentary, right-handed, and overweight. The mean handgrip strength was 13 kgf (right) and 11 kgf (left), and the average SARC-F score was 6. Higher weight-bearing values were observed on the left foot during stance. A positive correlation was found between SARC-F scores and weight-bearing on the right medial foot edge. In contrast, right-hand grip strength was negatively correlated with SARC-F. No other significant correlations were observed.
CONCLUSION: In this sample, certain plantar pressure variables and grip strength were correlated with sarcopenia suspicion. Future research should include larger samples and further gait parameters to deepen understanding. Investigating the relationship between plantar pressure, fall risk, and functionality may support preventive strategies and inform interventions focused on strength and balance training.
