Abstract
OBJECTIVE: The aim of this study was to investigate the impact of untreated hand diseases on hand grip strength, a value that is commonly used as a diagnostic parameter for sarcopenia and frailty in geriatric populations. We hypothesized that individuals with untreated hand diseases would have lower grip strength than those without hand diseases. METHODS: A total of 240 individuals aged at least 65 years were recruited and divided into two groups based on the presence or absence of typical hand diseases. Grip strength was compared between the two groups separately for men and women using a t-test, with each group consisting of 60 women or 60 men. RESULTS: Both women and men in the hand disease group exhibited significantly lower grip strength than those in the control group. CONCLUSIONS: These findings suggest that untreated hand diseases have a negative impact on grip strength, and this may introduce bias in the screening or diagnosis of sarcopenia and frailty. It is essential to consider the presence of hand diseases when measuring hand grip strength in older adults.
