Yubi Wakka Finger Ring Test
Purpose[edit | edit source]
The“Yubi-wakka" (finger-ring) test is a simple self-screening tool developed by the Japanese to check for sarcopenia among community-dwelling older adults.[1]
Technique[edit | edit source]
Conduct self-test in a seated position, no instrument required.
- Make a ring with the index fingers and thumbs of both hands
- Gently circle the thickest part of the non-dominant calf of the leg which is bent at a 90° angle
- Check whether or not the non-dominant calf circumference is“bigger,”“just fits”or“smaller” as compared with the finger-ring circumference.
Evidence[edit | edit source]
The "Yubi-wakka" assessment represents a highly useful approach for pinpointing older individuals who are vulnerable to sarcopenia, disability, and the risk of mortality.
- This test has the potential to enhance proactive measures in preventing sarcopenia by acting as an early warning for older adults to guard against developing this condition.[1][2]
- Given the generally robust health and longevity of the Japanese population, addressing sarcopenia becomes particularly crucial, particularly for individuals aged over 75 years.
- The existence of metabolic syndrome, as identified through the Yubi-wakka test, might constitute a potential risk factor for sarcopenia and subsequent frailty. This warrants heightened vigilance, particularly in the case of women[3].
