Dropping things can be a sign of multiple sclerosis, but it’s not specific to MS on its own. Loss of grip strength, fumbling with objects, and difficulty with fine motor tasks like buttoning a shirt are all recognized symptoms of MS that result from nerve damage in the brain or spinal cord. Up to 66% of people with MS experience some degree of upper limb dysfunction during the course of the disease, making it one of the more common physical effects.
That said, dropping things frequently has a long list of possible causes, from carpal tunnel syndrome to vitamin deficiencies to simple fatigue. What matters is context: whether you’re experiencing other symptoms alongside it, how suddenly it started, and whether it’s getting worse.
Why MS Causes You to Drop Things
MS damages the protective coating around nerve fibers in the brain and spinal cord. When that coating breaks down, electrical signals between your brain and your hands slow down or get scrambled. The result can show up in several ways that all lead to the same frustrating outcome of objects slipping from your grasp.
Weakness is the most straightforward cause. If the nerves controlling your hand and forearm muscles aren’t firing properly, your grip simply isn’t strong enough to hold a coffee mug or a pen. Numbness or reduced sensation plays a role too. Your hands rely on constant feedback from touch receptors to adjust grip pressure. When that feedback is dulled, you may not realize you’re loosening your hold on something until it’s already falling.
Tremor is another contributor. Even a mild tremor can make it hard to hold a full cup steady or manage small objects. The MS Society lists tremor as an early sign of MS, noting it can range from barely noticeable shaking to movements pronounced enough to spill a drink. Spasticity, or involuntary muscle stiffness, can also interfere by making your fingers less responsive when you need them to react quickly.
There’s also a cognitive component. Research has found a correlation between manual dexterity problems and cognitive changes in MS. Damage to the white matter in the brain can affect both thinking speed and motor coordination simultaneously, which means tasks that require you to plan a movement (like catching something that’s slipping) may be slower than they used to be.
Dropping Things as an Early Symptom
Hand clumsiness can appear early in MS, sometimes as part of the very first episode of symptoms. It doesn’t always show up dramatically. You might notice you’re dropping your phone more often, struggling to open jars, or having trouble with zippers. These changes can be subtle enough that you dismiss them for weeks or months before recognizing a pattern.
In MS, early symptoms tend to cluster. If dropping things is related to MS, you would typically notice at least one or two other symptoms alongside it. Common early signs include numbness or tingling in the hands or feet, vision problems (especially blurriness or pain in one eye), unusual fatigue that doesn’t improve with rest, or balance difficulties. A single symptom in isolation is less likely to point toward MS than a combination of symptoms, particularly ones that come and go in episodes lasting days to weeks.
The 2024 revisions to the McDonald criteria, which neurologists use to diagnose MS, now recognize that even neurological symptoms that don’t constitute a clear attack can sometimes contribute to a diagnosis when supported by MRI findings and other lab evidence. This means subtler symptoms like grip problems are taken more seriously in the diagnostic process than they once were.
Other Conditions That Cause Grip Problems
Before assuming MS, it’s worth knowing that several far more common conditions cause people to drop things regularly:
- Carpal tunnel syndrome compresses a nerve in the wrist and causes numbness, tingling, and weakness in the thumb and first three fingers. It’s one of the most frequent reasons people start dropping objects.
- Cervical radiculopathy (a pinched nerve in the neck) can weaken grip on one side and often comes with neck pain or pain radiating down the arm.
- Peripheral neuropathy from diabetes, B12 deficiency, or alcohol use damages nerves in the hands and feet, reducing sensation and coordination.
- Essential tremor causes shaking that worsens with movement and is far more common than MS-related tremor.
- Arthritis in the hands can weaken grip through joint pain and inflammation rather than nerve damage.
The key distinguishing features of MS-related grip problems are that they tend to come and go in episodes, may affect one side more than the other, and are usually accompanied by symptoms in other parts of the body (not just the hands).
How Doctors Assess Hand Function in MS
If a neurologist suspects MS, they’ll order an MRI of the brain and spinal cord to look for areas of nerve damage. But they also measure hand function directly. The Nine-Hole Peg Test is considered the gold standard for assessing manual dexterity in MS. It’s simple: you pick up nine small pegs one at a time and place them into holes on a board, then remove them. The test is timed, and your speed is compared to age-matched norms.
This test matters because standard disability scales used in MS don’t capture upper limb problems very well. Someone can score as mildly affected on a general disability measure while still struggling significantly with hand tasks. The peg test fills that gap and helps track whether hand function is stable, improving with treatment, or declining over time.
Exercises That Help Maintain Hand Function
Whether or not dropping things turns out to be MS-related, targeted exercises can improve grip strength and coordination. Occupational therapists who specialize in neurological conditions typically recommend a combination of strengthening, stretching, and fine motor practice.
A routine recommended by the MS Trust includes seven exercises targeting the arms and hands: single and double arm raises for shoulder stability, finger touch exercises to improve coordination between your thumb and each fingertip, table slides to maintain range of motion, wrist control movements, and forearm rotations. These are designed to be done seated or standing and can be adapted based on your current ability level. Consistency matters more than intensity. Doing a short routine several times a week preserves function better than occasional longer sessions.
Adaptive tools can also make a meaningful difference in daily life. Mugs with two handles, jar openers, button hooks, and weighted utensils reduce the dexterity demands of everyday tasks. These aren’t signs of giving up. They’re practical ways to stay independent while your hands aren’t cooperating.
