Strong hands are essential to everyday function. Whether you’re opening jars, carrying bags of groceries, typing at a keyboard, or holding a steering wheel, you rely on powerful, coordinated hands for countless activities. Weak grip strength can make even basic tasks frustrating and difficult.
Many people believe that weak hands are simply a part of aging. While age is certainly a factor, weakness can be caused by a variety of underlying conditions that impact the muscles, tendons, nerves and joints that facilitate hand movements.
When patients notice a sudden decrease in hand strength, they may benefit from seeing an orthopaedic hand specialist. A hand doctor will work to determine exactly what is causing your symptoms and which treatment will provide the best solution.
Age-related muscle loss
Sarcopenia, or age-related muscle loss, is one of the most common causes of diminished grip strength. As you age, you gradually lose muscle mass and strength throughout your body, including your hands and forearms.
This can make it difficult to hold onto things or maintain a strong grip for long periods of time. While you can’t stop the aging process, exercising and strength training can help slow down muscle loss and keep your hands as strong as possible.
Arthritis of the hand and wrist
Arthritis is another common cause of weak grip strength. Conditions like osteoarthritis and rheumatoid arthritis affect the small joints in your hands and wrists. Over time, the surfaces of these joints can become damaged or worn down, leading to pain and stiffness. You may begin to compensate by not using your hand as much, which can cause your strength to diminish over time.
In severe cases, arthritis can cause deformities in the joints of your hand, making normal function difficult. Thumb arthritis is also well known for limiting pinch and overall grip strength.
Carpal tunnel syndrome
When the median nerve is compressed as it travels through the wrist, you can experience symptoms of carpal tunnel syndrome. This condition often causes numbness, tingling and weakness in the hand.
Many people begin to notice their weak grip strength when items start slipping from their hands. Simple tasks that require fine motor skills may become more difficult to perform. As the condition progresses, muscles at the base of your thumb can weaken, leading to a loss of overall grip strength. Treating carpal tunnel early can prevent permanent nerve damage and loss of hand function.
Tendon injuries
Tendons in your hand help connect muscles to bone and allow your fingers and thumb to move freely. If you injure your tendons, you may experience a dramatic decrease in your grip strength.
These injuries can occur from traumas, sports accidents, workplace injuries or even deep cuts. Sometimes, even minor tendon injuries can cause issues with how your hand functions.
Treatment for tendon injuries varies with severity and may include splinting, hand therapy, surgery and rehabilitation.
Nerve compression
In addition to carpal tunnel syndrome, other conditions can cause nerve compression and weaken your grip. One of the more common is cubital tunnel syndrome. This condition is caused by compression of the ulnar nerve, which passes near the elbow. This nerve branches into many small muscles in your hand, which allow your fingers and thumb to move.
Weakness may occur when gripping objects, picking up small items, or turning doorknobs. Loss of finger control is also common with this condition. If left untreated, long-term nerve compression can cause muscle atrophy and permanent weakness.
Hand/wrist fractures
Broken bones in your hand, fingers, or wrist can affect your grip strength. This can be especially true if the fracture affects the joint’s alignment or fails to heal properly.
Even if the bone heals correctly, you may experience weakness, stiffness, and swelling for several months after the injury. Some people develop scar tissue or a limited range of motion that prevents their fingers from closing completely around objects. Physical rehabilitation is often necessary to restore strength and function to your hand after a fracture.
Repetitive stress injuries
Have you ever experienced tendonitis in your hand or wrist? Inflammation due to overuse can really take a toll on your hands. Whether you work in construction or type all day at a desk, your hands can become weary from repetitive tasks.
Over time, repeating the same hand motions can cause increased weakness. Simple movements like gripping something for too long can cause pain and discomfort. Taking breaks, adjusting your workspace, and doing hand exercises can help.
If you are experiencing weakness in your hand that does not seem to be going away on its own, contact a hand specialist. Simply searching online for a “hand surgeon near me” can help you find a qualified specialist in your area. They can diagnose the cause and develop a treatment plan to help maintain your quality of life. Early intervention can increase your chances of restoring full strength to your hands.
