Grip Strength and Frailty: The New Essential Biomarker
Grip strength has emerged as an indispensable data point for assessing and monitoring patients with complex health conditions. The measurement of grip strength in aging patients provides a fast, non-invasive gauge of functional health as it is closely linked to sarcopenia and frailty.
Imagine if a simple handshake could offer powerful insights into someone's frailty.
This isn't just a metaphor. Grip strength has emerged as an indispensable data point for assessing and monitoring patients with complex health conditions.
The measurement of grip strength in aging patients provides a fast, non-invasive gauge of functional health as it is closely linked to sarcopenia and frailty.
Frailty increases and physical function decreases as a result of reduced muscle strength.
This heightens the risk of events such as falls or infections, which drive up healthcare utilization and costs.
This document explains how grip strength can be used in clinical practice to assess sarcopenia and frailty in aging patients. Read on to find out, what does weak grip strength indicate?
Must-Know Metrics: Grip Strength and Frailty
Grip Strength and Frailty
Grip strength below 44.1 lbs* for men and 28.8 lbs* for women is one of the five key criteria for identifying frailty according to the Fried Frailty Phenotype (FFP). [Fried et al., 2011]
Grip Strength and Mobility Limitations
Grip strength below 48.7* lbs for men and 32.0 lbs* for women is a key threshold for identifying mobility limitations, particularly a walking speed of less than 0.8 m/s. [Delinocente et al., 2021]
Grip Strength and Sarcopenia
Grip strength below 41.0 lbs* for men 24.3 lbs* and for women is a key criterion for diagnosing sarcopenia, as defined by the European Working Group on Sarcopenia in Older People (EWGSOP2). [Cruz Jentoft et al., 2014]
*Note that all cut off points have been converted to GripAble-equivalent measurements for consistency
Grip Strength and Frailty in Practice
Clinical Application
Measure grip strength during routine check-ups to assess risk factors and track trends over time.
For high-risk patients, consider providing a hand dynamometer for regular, at-home monitoring and frailty assessment. Grip strength dropping below cut-off points or decreasing by more than a quartile requires attention.
Patient Empowerment
Give patients access to their grip strength scores. A clear, tangible measure they can easily understand and actively improve with guidance.
Unlike blood pressure, grip strength measurement is relatable and empowering, enabling patients to track their progress as a key indicator of their independence.
Practical Considerations
Let grip strength support other standard measurements in geriatric assessments:
- Replace gait speed tests with grip strength in scenarios where falls risk is significant
- Add objective insights to patient-reported outcomes with this minimally invasive tool.
Impact: Grip Strength and Frailty
Reduce Utilization: identify disease early and understand patient prognosis
Improve Patient Satisfaction: where appropriate, give patients a quick, non-invasive tool to monitor disease status and response to treatment at home
Support Risk Adjustment: quantify disease and treatment impact by using grip strength results as an objective measure of muscle loss
