Hand strength is the ability to perform tasks such as grasping and pinching. Medical professionals measure hand strength using the Medical Research Council scale and a second degree scale to determine any disabilities. Various exercises can help improve hand strength, including gripping and pinching exercises. Tools such as hand grippers, stress balls, and extension bands can also aid in improving hand strength.
Hand strength refers to the hand’s ability to perform tasks such as grasping and pinching, and how well these tasks can be performed. Different types of motion can help an individual determine a measure of hand strength, including finger flexion. If an individual wishes to improve hand strength, various exercises can help build muscles in the hands. Understanding hand strength measurements is important because the numbers can indicate possible neuromuscular disorders.
Medical professionals typically measure hand strength along a spectrum such as the Medical Research Council scale. In this method, the practitioner will ask the patient to perform hand muscle strength tests manually or using a machine such as a dynamometer. The evaluator then rates the patient’s abilities on a scale of one to five, with one representing no muscle movement and five representing normal muscle contraction.
A second degree is then awarded in order to determine any disabilities. This second degree scale measures a patient’s muscle function or dysfunction based on skill tests and scores. Grades range from one to ten on the clinical rating scale, and a higher grade indicates worsening muscle function. For example, a grade of two might signal a mild neuromuscular disability such as carpal tunnel syndrome, while a grade of nine is likely indicative of tetraplegia. Decreased muscle strength and function in the hand can emerge as a symptom in a range of conditions, from nerve damage to tendon injuries.
Several methods can assess hand strength, especially gripping and pinching exercises. Grip strength, also known as crush strength, refers to how much force a hand produces when it transfers from an open-palm position to a clenched fist. The force created when you press your fingers together is another good indicator of hand strength. Other movements used to evaluate hand function include wrist flexion, palm flexion, and gripping an object with the fingers and thumb for a specified amount of time.
Many tools can serve as aids in improving hand strength, and all of these tools should be used in proportion to hand size. The opening and closing of a hand gripper can facilitate an increase in grip strength, while dexterity or maneuvering of the stress ball and extension bands placed on the fingers can also improve overall muscle strength in the hand. Additionally, individuals should keep their hands warm and maintain blood flow to the hands to preserve hand function. After a hand grip workout, many trainers will also use a contrast bath, in which the hands are immersed in alternating 90-second cycles of hot and cold water. Any serious exercise regimen should be discussed with a certified medical professional.
