Improving Fine Motor Skills

A loss of fine motor skills is a common symptom of neurologic conditions. Try these creative ways to improve dexterity or adapt to changes.

Eight years ago, Schuetz’s creative passions were threatened when he was diagnosed with Parkinson’s disease and began experiencing worsening tremors in his right hand. Eventually his writing diminished, as did the beautiful lettering he once was so proud of. The loss was a wake-up call, says the 66-year-old resident of Timonium, MD.

“I have a lot to lose if I let this disease take away my hand dexterity,” says Schuetz. “Not only the sense of feeling productive, but a bit of my identity, too. It’s important to keep my hand skills up to par.”

Decreased Dexterity

Parkinson’s disease, with its tremors, freezing, and stiffness, is not the only neurologic condition that can cause hand and finger difficulties like Schuetz’s. For people with essential tremor, the shaking worsens with activity. Those with multiple sclerosis (MS) often experience lack of coordination and hand weakness. Dystonia, a movement disorder that causes uncontrollable muscle contractions, can result in twisted posture and cramping, which can affect hand dexterity. Neuropathies may cause numbness and weakness. And about eight out of 10 stroke survivors experience weakness on one side of the body, including the hand, according to a 2014 study in the Journal of Neuroengineering and Rehabilitation.

For people with MS, trouble with dexterity can happen at any stage of the disease, says Michael J. Olek, DO, associate professor of neurology at the Touro University Nevada College of Osteopathic Medicine in Henderson, NV. “Patients may have trouble with handwriting, using keyboards, and preparing meals.”

Dearth of Studies

Research on how to improve fine motor skills affected by neurologic disorders is minimal, especially compared with research on aerobic exercise, says Lisa M. Shulman, MD, FAAN, distinguished professor in Parkinson’s disease and movement disorders at the University of Maryland School of Medicine.

Patients often worry more about improving their walking and balance and less about improving dexterity, Dr. Shulman says. “I think that’s because there are many workarounds for weak hands.” For example, people with poor fine motor skills can buy clothing with fewer buttons and zippers and shoes with easy fasteners, she says. They can also pick up prepared meals so they don’t have to cook.

Still, it’s important to focus on dexterity, Dr. Shulman says. She and patients like Schuetz offer the following advice for retaining dexterity or adjusting to its loss.

8 Ways To Address Dexterity

  1. Talk to your doctor. Patients are more likely to tell their doctors about problems with walking than loss of dexterity, says Dr. Shulman. “What I’ve observed is that patients who exercise are almost always using their larger muscles, especially in the lower body, when using a treadmill or stationary bike, which preserves lower body function. Meanwhile, their fine motor dexterity disproportionately worsens.” She encourages all patients to inform their neurologists and health care team about any loss of fine motor skills and ask for help in improving and maintaining function.
  2. Work with an occupational therapist. Physical therapy and speech therapy are more commonly part of a treatment plan than occupational therapy, says Dr. Shulman. “It’s important that neurologists encourage more patients to engage in occupational therapy.” It helps enhance independence, productivity, and safety in all activities related to personal care, leisure, and employment, says Kathy Zackowski, PhD, OTR, senior director of patient management, care, and rehabilitation research at the National Multiple Sclerosis Society.
  3. Consider writing aids. For many people, the simple task of signing a check or restaurant bill or writing a to-do list becomes problematic. To make writing easier, use a pen grip or fatter pens, advises Rick Schrader, 64, a former software salesman in Herndon, VA, who has hereditary ATTR amyloidosis, a rare condition that affects his nerves and hand mobility. His hands get cold easily and lose sensation, but he still balances his business checkbooks every Saturday. “I don’t write fast anymore, but if I take my time I can still write clearly.”
  4.  Write mindfully. Writing quickly and unthinkingly may result in small, cramped handwriting and tightness in your hand, said Dr. Zackowski. “Try not to rush your writing, and switch to print instead of cursive. Using lined paper provides a guide and forces you to use bigger letters, which helps keep writing more legible.” She adds that using a computer keyboard may be easier if you don’t mind typing. And for those who are used to typing but now find it difficult, many keyboard modifications are available, including a key guard that helps users press the key they want without accidentally pressing other keys.
  5. Use adaptive devices. For assistance when getting dressed, you can use reaching aids, button hooks, zipper pulls, Velcro shoe fasteners, or shoe horns, says Dr. Zackowski. To help with cooking and navigating the kitchen, she recommends tools such as nonskid placemats, utensils with oversized or angled handles, and rocking T knives, which cut food using a rocking motion. In the bathroom, Dr. Zackowski suggests getting a shower chair and a nonskid bath mat and installing grab bars. For grooming, Schrader uses an electric toothbrush and razor. Others may want to install a hands-free hairdryer on the wall or vanity.
  6. Try different utensils. Poor dexterity can make eating with a fork difficult, says Kathy Villella, who has primary progressive MS. Whenever she eats in a restaurant, Villella orders food such as ravioli that is easy to pick up with a spoon. John Martin, 82, of Independence, MO, who was diagnosed with essential tremor in 2008, uses weighted spoons and knives and eats with his left hand because his right hand is more affected by tremors.
  7. Keep fit. Staying active is the key to maintaining function and dexterity, says Carolee J. Winstein, PhD, PT, director of the motor behavior and neurorehabilitation laboratory at the University of Southern California in Los Angeles. “Work with your doctor and therapists to find a fitness and exercise plan that will help you maintain function in your hands and fingers.” Schuetz practices yoga, which he says helps him maintain strength and dexterity in his arms and hands.
  8. Improve fine motor skills. To keep his fingers flexible and loose, Schuetz kneads therapy putty, a thick Play-Doh-like paste that varies in pliability from easy to hard. In addition to practicing yoga and kneading therapy putty, Schuetz continues to draw and paint. He says gripping the pencils and paintbrushes strengthens his fingers.

Schuetz also makes rings out of spoons, a hobby he started in the 1970s. Today, it provides another way to stay physically and creatively engaged. He hopes to move beyond rings into small bronze sculptures of yoga poses. “I want to bring together my two main interests—art and yoga—and keep my hands busy and happy.”

Spinal Cord Stimulation as PD therapy

A new study finds that spinal cord stimulation could represent an alternate therapy for people with Parkinson’s disease that is resistant to conventional treatments. The researchers claim that this emerging technology may help decrease pain and improve mobility.

Close to 1 million people may be living with Parkinson’s disease in the United States. This long-term degenerative disorder results from damage to nerve cells in the brain that produce dopamine.

As the symptoms of Parkinson’s develop, a person may first experience a tremor in one hand and stiffness elsewhere in the body. The four key symptoms are:

  • a tremor
  • stiffness or tightness in the arms, legs, or elsewhere in the body
  • slowed movement and difficulty initiating and coordinating movement — possibly presenting as a loss of facial expression or a slow, stuttering walk
  • difficulty with fine movements, such as doing up buttons

Ultimately, a person experiences problems maintaining balance, and some people with Parkinson’s also develop dementia. Certain people only develop motor symptoms and others have cognitive symptoms, and doctors are still unsure why this is.

Some people refer to dopamine as the “feel-good” hormone or chemical messenger. It has various roles, including in movement coordination, and it is an active player in the brain’s reward system.

Most people with Parkinson’s also develop at least one nonmotor symptom. The most common of these are sleep disturbances, a loss of smell, pain, constipation, and excessive sweating.

People may also experience anxiety and neuropsychiatric symptoms, such as depression, apathy, or psychosis.

This wide array of symptoms can affect relationships and cause people with Parkinson’s to have lower self-worth and lose their sense of identity.

While the cause of Parkinson’s remains unknown, prescription treatments for dopamine deficiency and deep brain stimulation (DBS) are the gold-standard approaches.

But dopamine treatment can cause side effects, such as dyskinesias, involuntary twisting movements of the body. These usually diminish as the drug wears off. Other adverse effects include gastrointestinal disturbances, hallucinations, anxiety, and muscle fatigue.

Meanwhile, DBS can cause brain bleeding, infection, and seizures.

Given the urgent need for treatments that alleviate Parkinson’s symptoms with minimal risks, a group of researchers has now investigated an alternate approach: spinal cord stimulation. They have published their findings in the journal Bioelectronic Medicine.

Assessing an alternate therapy

The researchers set out to determine whether spinal cord stimulation could be a singular therapy for Parkinson’s disease and a salvage therapy, in people for whom DBS is increasingly ineffective.

The study included 15 participants, with a mean age of 74 years. On average, they had received the diagnosis of Parkinson’s disease 17 years earlier.

Eight had undergone DBS previously, and the others had only received medication, including pain relievers, as Parkinson’s treatment.

All experienced chronic pain that was resistant to pain relief medication and changes in their treatment for the disease. When a particular nerve was involved, drugs called nerve blocks had been ineffective.

Once the study had begun, electrodes were surgically implanted under the participants’ skin near their spines.

The participants could choose to receive mild electric currents in three stimulation modes: continuous tonic stimulation, continuous burst stimulation, or a cycling mode with burst stimulation, which provided stimulation for 10–15 seconds at a time, separated by pauses of 15–30 seconds.

 
Relief from pain and improved mobility

The researchers observed that the 15 patients experienced “significant improvement” after using the spinal cord stimulator device.

Based on the visual analog scale of pain intensity — the seven patients who had never received DBS experienced a 57% reduction, on average. For those who had received DBS in the past, the average reduction in pain intensity was 61%.

In addition, the researchers found that participants who opted for the cycling mode experienced, on average, a 67% reduction pain, using the same scale. By comparison, those who chose continuous burst stimulation had, on average, a 48% reduction in their pain scores.

Of the 15 patients, 11 had been able to complete a 10-meter walk before and after the study. After the stimulation, eight people (73%) in this group showed an average improvement of 12% during their 10-meter walks. The researchers used these walks to assess the participants’ mobility and gait.

They also used a “timed up-and-go” test to measure how long it takes a person to get up from a chair, walk 3 meters, turn around, walk back to the chair, and sit down. Among the 11 participants who completed this test, seven (64%) showed improvement in their completion times.

The patients who chose a continuous burst pattern had an 18% improvement in their timed up-and-go scores. However, those who chose the cycling mode had a 7% worsening in these scores.

While many of the results seem promising, it is important to note that spinal cord stimulation carries some risks and may cause complications, including bleeding at the site of insertion.

The researchers also acknowledge that their study design had a limitation: They were unable to determine whether the improvements in scores stemmed from the stimulation itself or the resulting decrease in pain, which allowed for more mobility.

The team of researchers, based in the U.S. and Japan, observe:

“Spinal cord stimulation is an emerging technology that can potentially be utilized to treat both the motor and nonmotor symptoms, such as pain, that patients with Parkinson’s disease deal with on a daily basis.”

Another limitation involved the fact that the patients did not receive the spinal cord stimulators in the exact same location, due to differences in how their pain presented. Also, not every patient was able to return and complete the mobility tests, which reduced the already small sample size.

In addition, this small study did not include a control group, so some changes in pain scores could result from a placebo effect.

This research should thus be regarded as a proof-of-concept study. Further evaluation in larger trials is needed.

Finally, some researchers involved in this study have disclosed potential conflicts of interests due to affiliations with medical device companies and pharmaceutical companies, including Medtronic, Abbott, Boston Scientific, Kyowa Kirin, Boehringer Ingelheim, AbbVie, and FP Pharmaceutical.

Best Workout for Brain Health

We know that exercise is stellar for brain health, and a good sweat can even help generate new neurons in the hippocampus—aka, the brain region associated with memory, learning, and emotions. But when it comes to the different types of movement—running, squats, yoga, et al.—does one workout reign supreme?

Of course, any type of movement that gets your blood flowing is brain-healthy—we like to say here at mbg, the healthiest exercise for you is the one you love. But if neurologists Dean Sherzai, M.D., and Ayesha Sherzai, M.D., had to pick a favorite? Well, it would be stairs. 

The best exercise for brain health, according to the Sherzais. 

In terms of growing BDNF (brain-derived neurotrophic factor), a molecule that can actually grow brain cells, “leg strength is by far the most important,” notes Dean. In fact, research shows that using the legs, particularly in weight-bearing exercise, sends signals to the brain that are crucial for producing healthy neural cells. Another 2015 study showed that out of 324 healthy older women, those with stronger leg power had fewer brain changes associated with cognitive aging after 10 years. “It’s almost like bigger legs, bigger brain,” Ayesha adds. 

So what, specifically, makes stairs so sublime? Well, not only do they target leg strength (a nod to the research mentioned above), but there’s also an aerobic component to it. Many experts believe aerobic (read: cardio) exercise is the best for your brain since it increases your heart rate, which means it pumps more oxygen to your body and brain. “I think [stairs] may be one of the healthiest exercises that I can think of,” Dean says. 

How long should you climb stairs?

You may be thinking: How long should I climb stairs to reap these benefits? According to the Sherzais, any amount that gets your blood pumping is great for brain health—so the specific time may vary depending on your personal workout habits.  

Of course, you can calculate just how much your heart rate increases (with wearable monitors and the like), but in case you don’t have that tech on hand, Ayesha recommends noticing when you’re out of breath. “As soon as you feel that you have difficulty finishing a sentence, you’re panting, and you’re breaking a sweat, I think that’s a great place to be,” she notes. “That’s a great place where your BDNFs are flushing your body.” 

Although, if you do choose to climb stairs (without a machine, we should add), be super careful trotting down: “There’s more damage to the menisci and the ligaments going down,” Dean notes. So be gentle during your reps.

The takeaway. 

While the Sherzais love a good stair workout for brain health, just remember that the “healthiest” exercise is the one you love—because that means you’ll stick to it consistently. If that happens to be a nonaerobic exercise, like yoga, so be it! You can certainly find some research to tout its positive effects on the brain, too
