Abstract
Background/objectives: Handgrip strength is a critical indicator of overall health, particularly in older adults, and is associated with frailty, sarcopenia and risk of adverse health outcomes. Precise and reliable measurement instruments are necessary to ensure accuracy in personalised diagnostic evaluations. This study aimed to assess the inter-instrument reliability and agreement between the Jamar Plus+ digital and Jamar hydraulic dynamometers in measuring handgrip strength.
Methods: A cross-sectional study was conducted to assess the handgrip strength of older individuals in the community aged more than 60, using the Jamar Plus+ digital and Jamar hydraulic dynamometers. The inter-instrument reliability and agreement between the devices were evaluated using Intraclass Correlation Coefficients (ICCs) and Bland-Altman analysis.
Results: A total of 109 participants with a mean age of 66±5.3 years were included in this study. The Jamar Plus+ digital dynamometer recorded significantly higher handgrip strength measurements (27.0±7.1 kg) compared with the Jamar hydraulic dynamometer (21.0±6.7 kg). The ICCs between the two devices ranged from 0.67 to 0.70, indicating moderate reliability. Bland-Altman analysis revealed a consistent overestimation of handgrip strength by the Jamar Plus+ digital dynamometer, with systematic biases of 4.8 kg in men and 6.26 kg in women compared with the Jamar hydraulic dynamometer.
Conclusion: The Jamar Plus+ digital dynamometer consistently overestimated handgrip strength compared with the Jamar hydraulic dynamometer, but both devices demonstrated moderate reliability. The Jamar Plus+ showed greater responsiveness to variations in strength. Selecting appropriate diagnostic tools is crucial for optimising individualised health assessments in older adults.
期刊介绍：
Published quarterly in print and continuously online, BMJ Supportive & Palliative Care aims to connect many disciplines and specialties throughout the world by providing high quality, clinically relevant research, reviews, comment, information and news of international importance.
We hold an inclusive view of supportive and palliative care research and we are able to call on expertise to critique the whole range of methodologies within the subject, including those working in transitional research, clinical trials, epidemiology, behavioural sciences, ethics and health service research. Articles with relevance to clinical practice and clinical service development will be considered for publication.
In an international context, many different categories of clinician and healthcare workers do clinical work associated with palliative medicine, specialist or generalist palliative care, supportive care, psychosocial-oncology and end of life care. We wish to engage many specialties, not only those traditionally associated with supportive and palliative care. We hope to extend the readership to doctors, nurses, other healthcare workers and researchers in medical and surgical specialties, including but not limited to cardiology, gastroenterology, geriatrics, neurology, oncology, paediatrics, primary care, psychiatry, psychology, renal medicine, respiratory medicine.
