Hands and Parkinsons - the Research

Do you avoid writing letters, opening jars, and wearing clothing with buttons because it has become more difficult? We use our hands all day to help us with activities like getting dressed, eating, and even communicating with others whether it be mailing a card or sending a text message. You might be doing exercises to improve your leg strength and your endurance, but are you doing any exercises to improve your hand strength, flexibility, and coordination? Read ahead as Calli Hutchison, PT, DPT shares how our hands can be affected by Parkinson’s disease and what the research suggests can be done to improve hand strength, coordination, and flexibility.


Many people with Parkinson’s have a tremor that can make daily activities such as handwriting, eating, and dressing more challenging1. But even those without a tremor can have a harder time using their hands because of bradykinesia and rigidity making hand movement slower and smaller1-4. You may also notice muscle weakness and decreased dexterity in your hands1,4. Unfortunately, research suggests medication and deep brain stimulation do little to improve hand dexterity2-5. The good news is just like we can exercise to improve our walking and balance, research indicates we can exercise to improve our hand strength and coordination too1,2,5


When exercising your hands, apply the same principles that you would in other Parkinson specific exercises including making the hands as big as possible, fast movements, or adding dual tasking for an increased challenge4. Also remember the importance of specificity, meaning if you want to improve your handwriting, practice handwriting or if you want to improve your ability to pick up small objects, practice picking up small objects3,5.


Research has shown that even one 15-minute exercise session can increase hand strength and dexterity short term suggesting that you can use hand exercises prior to activities to help prepare and activate the muscles needed for improved performance of a task1. Use of visual targets can also improve your performance such as writing on lined paper to increase letter size and legibility2. 

To Improve Handwriting

Hand and finger flicks

Holding a scarf as you write big letters in the air

Writing on lined paper with each letter taking up 3+ lines

To Improve Opening jars or doors

Squeezing a stress ball

Wringing out a towel

Holding a weight as you move your wrist in different directions

To Improve Picking up small objects

Pinch putty between thumb and fingers on both hands and pull apart

String beads together

Pick up different sized coins

To Improve Buttoning a shirt

Cut a slit in a piece of felt and push coin or button through slit

Thread nuts on a bolt

Pull apart small pieces of putty

Hand exercises are some of the easiest to fit into your schedule. They can be performed while riding in the car, waiting for an appointment, or watching tv. Just like with other exercises, do these regularly to maintain and improve fine motor skills needed for your everyday activities like dressing, eating, and writing2,4. Learn more about what exercises you can do to improve your hand movement in our new guided plan all about hands!

Calli Hutchison, DPT Parkinson Disease Exercise Specialist

Calli first discovered her passion for working with people with Parkinson disease in 2014, as an undergrad working on a PD research study.  A few years later, she first joined the PWR! family as a physical therapy student on a clinical rotation. Calli found working at the PWR!Gym so deeply rewarding that, after graduation, she accepted a position as one of our full-time physical therapists, and she, her husband, and their three cats, Nugget, Peanut, and Khaleesi, moved to Tucson. In addition to treating clients, Calli organizes our Wellness Series and social events.

Calli offers physical therapy to clients in Arizona and wellness consultations to those outside of Arizona.

Outside the gym, Calli loves to travel—she’s been to four continents and she and her husband, Taylor, visit craft breweries everywhere they travel to.
