How to Manage Finger Weakness in Welander Distal Myopathy

At a Glance

Finger extension weakness is an early hallmark sign of Welander distal myopathy. While there is no medical cure, occupational therapy, adaptive tools, and customized hand splints provide essential mechanical support, improve grip, prevent contractures, and help maintain daily independence.

What to Keep in Mind

Losing fine motor skills and having trouble straightening your fingers can be incredibly frustrating and scary. This finger extension weakness is one of the hallmark early signs of Welander distal myopathy (WDM) [1]. While the underlying muscle weakness cannot be reversed or “fixed” with medication [2], there are effective strategies to manage it. By working with specialists and using adaptive devices, you can support your hands, improve your grip mechanics, and maintain your independence in daily tasks [3].

The Role of Specialized Therapists

Because WDM is rare, a multidisciplinary approach is highly recommended. Working with an occupational therapist (OT)—ideally a certified hand therapist (CHT) or someone with experience in neuromuscular conditions—is a key part of your care [3]. Occupational therapy focuses on helping you perform the activities of daily living that matter most to you, such as eating, dressing, or working at a computer [4].

A specialized therapist can evaluate your hand function and help you:

  • Adapt daily tasks: Learn new ways to approach activities that require finger extension, such as typing or buttoning clothes.
  • Select adaptive tools: Identify specialized utensils, easy-grip pens, or altered keyboards that reduce the strain on your hand muscles.
  • Prevent contractures: When extensor muscles weaken, the stronger flexor muscles can cause your fingers to permanently curl inward (a contracture). A therapist can teach you gentle range-of-motion exercises and passive stretches to maintain joint flexibility.
  • Conserve energy: Develop strategies to manage fatigue and protect your joints during repetitive tasks.

Hand Splints and Assistive Devices

One of the most effective ways to manage finger weakness in WDM is through the use of customized, lightweight hand splints or orthoses. Because WDM affects the extensor muscles (the muscles that pull the fingers straight and lift the wrist), a splint can provide the mechanical support that your muscles can no longer fully supply. It is important to know that wearing a supportive splint does not make your muscles “lazy” or accelerate muscle wasting; rather, it allows you to use your hands more effectively.

Assistive devices can significantly improve usability and enhance your quality of life [5]. These devices help by:

  • Supporting natural posture: Splints keep your fingers and wrist in a functional, neutral position, preventing your fingers from curling into a fist.
  • Improving grip mechanics: To grasp an object effectively, your hand first needs to open. By helping you straighten your fingers, a splint allows you to position your hand around objects like a cup or a steering wheel.
  • Maintaining independence: Lightweight supports can make daily tasks like typing, eating, and personal care much more manageable.

What to Keep in Mind

There is currently no pharmacological cure for WDM [2], but researchers continue to study the genetics and molecular causes of the disease to develop future therapies [6][7]. Because WDM is slowly progressive [1][8]—meaning changes typically happen over years rather than months—your needs may gradually change over time. It is important to have your hand splints regularly evaluated and adjusted to ensure they remain comfortable and effective.

Finally, while this page focuses on the hands, it is common for similar progressive weakness to affect the extensor muscles in the feet and toes (which can cause tripping or foot drop) [1]. Discuss any changes in your walking with your care team so they can provide appropriate lower-body support as well.

Common questions in this guide

How can occupational therapy help with finger weakness from Welander distal myopathy?
An occupational therapist can teach you new ways to perform daily tasks and recommend adaptive tools to reduce hand strain. They also provide gentle stretching exercises to maintain joint flexibility and prevent your fingers from curling permanently inward.
Will wearing a hand splint make my WDM hand muscles weaker?
No, wearing a supportive splint does not make your muscles lazy or accelerate muscle wasting. Instead, a custom splint provides necessary mechanical support to hold your fingers in a functional position, allowing you to use your hands more effectively.
Is there a medication to fix finger extension weakness in WDM?
Currently, there is no pharmacological cure to reverse muscle weakness in Welander distal myopathy. However, adaptive devices, specialized hand splints, and occupational therapy can effectively help manage symptoms and maintain your independence.
What should I do if I also start tripping or noticing foot weakness?
It is common for the progressive weakness seen in WDM to also affect the extensor muscles in the feet and toes, which can cause foot drop or tripping. You should discuss any changes in your walking with your doctor so they can provide appropriate lower-body support.

Questions to Ask Your Doctor

Curated prompts to bring to your next appointment.

  1. 1.Can you refer me to an occupational therapist or a certified hand therapist who has experience working with neuromuscular conditions?
  2. 2.What type of lightweight hand splint (static vs. dynamic) would you recommend for my specific pattern of finger weakness?
  3. 3.How frequently should my hand function and grip strength be evaluated?
  4. 4.Are there specific passive stretching exercises I should do to prevent contractures without causing overwork fatigue?
  5. 5.How can we ensure that my care plan also addresses any similar weakness developing in my feet or toes?
