Why does your therapist care about your grip strength?

Whether you’re seeing a therapist or a doctor, grip strength is routinely tested — and for good reason. You might wonder why your hand strength matters when your knee or shoulder hurts. Grip strength is more than a hand measure: it’s a reliable indicator of overall function and an early sign of frailty.
Fried’s frailty criteria include five signs:

• Unintentional weight loss (≥10 lb or ≥5% in a year)

• Feeling exhausted

• Low physical activity

• Slow walking speed

• Weak grip

Three or more signs indicate frailty; one or two indicate prefrailty. Grip strength, measured with a hand dynamometer, is an objective and often early marker. Low grip strength predicts higher risk of disability, falls, hospitalizations, and death, and it frequently responds well to treatment.
Grip strength also reflects how much you can interact with your environment and maintain independence. If opening a water bottle is difficult, tasks like carrying groceries, putting away dishes, and doing laundry are likely more fatiguing or may not be done at all. That loss of function increases the chance you'll need caregiver support or more intensive interventions.
