Objective[edit | edit source]
Grip strength is a measure of muscular strength or the maximum force/tension generated by one’s forearm muscles. It can be used as a screening tool for the measurement of upper body strength and overall strength. It is most useful when multiple measurements are taken over time to track performance.
Research indicates that grip strength in midlife can predict physical disability in senior years and help evaluate a patient’s overall health. All you need is a hand dynamometer and the handgrip strength norm tables.
Intended Population[edit | edit source]
Grip strength can be used in numerous situations to evaluate and track many health-related conditions
The Elderly.[edit | edit source]
Grip strength grows weaker as we age, which eventually begins to affect our day-to-day. Simple things like opening jars, carrying groceries, and turning doorknobs are made more or less difficult depending on the strength of the hands.
It is also a reliable indicator of many health conditions associated with ageing
- A 2018 prospective study found better handgrip strength was associated with cardiac structure and function in a pattern indicative of less cardiac hypertrophy and remodeling. These characteristics are known to be associated with a lower risk of cardiovascular events.
- In older patients with hip fractures, early grip strength evaluation might provide important prognostic information regarding the patient's future functional trajectory.
- A 2017 scoping review reported the use of handgrip strength as a way to monitor cognitive changes was important and that reduced handgrip strength over time may serve as a predictor of cognitive loss with advancing age. Similarly, a 2016 review found that handgrip strength has a predictive validity for the decline in cognition, mobility, functional status and mortality in older community-dwelling populations.
- ) as low grip strength in older inpatients is associated with poor healthcare outcomes including longer length of stay and mortality. A high percentage of older patients were identified to be at risk of poor healthcare outcomes as a result of low grip strength and would benefit from nutritional and exercise interventions.
- A cross-sectional study (2020) shows a low correlation between the handgrip strength and standard strength measures of the lower limbs (hip, knee, and ankle extensor/flexor muscles), and functional capacity in older women.
In Conditions of the Upper Limb[edit | edit source]
Method of Use[edit | edit source]
To assess grip strength, the Jamar dynamometer is recommended by the American Society for Surgery of the Hand and the American Society of Hand Therapists. These are expensive items and many cheap dynamometers are on the market on-line. They are quite is suitable for physical therapy, or in the doctor’s clinic.
- The client is seated with shoulder adducted, elbow flexed to 90 degrees, and forearm and wrist neutral. The therapist places the dynamometer in the client’s hand while gently supporting the base of the dynamometer, and he/she instructs the client to squeeze as hard as possible. Grip force should be applied smoothly, without rapid jerking motion. Allow the wrist to extend during the grip.
- Standard grip test: Three trials on the second handle-width setting.
- Normative data exists for grip and pinch strength testing. In addition, compare readings with the client’s opposite extremity.
- Before performing strength testing check whether there are any healing tissues that can be damaged by this test and use another outcome measure.
The study measuring the validity of the digital MicroFET3 dynamometer with Jamar dynamometer suggests good validity with the MicroFET3 dynamometer. The comparison showed that the MicroFET3 dynamometer indicated age-related declines in the maximum grip-force and showed slower and more inconsistent maximal hand-grip strength generation by the elderly.
