What patient need does Carbonhand address?

Many individuals with neurological, neuromuscular, orthopedic, or age-related conditions experience reduced grip strength and limited endurance in the hand, despite retaining the ability to initiate voluntary movement.

These patients often:

Can open and close the hand, but lack sufficient force to grasp, lift, or hold objects
Experience rapid fatigue during repetitive or sustained grasp
Rely on compensatory strategies or assistance, limiting independence in daily activities
Are unable to fully benefit from conventional therapy or passive assistive devices in real-world tasks

Carbonhand is designed to support patients who have preserved intention to grasp but insufficient strength or endurance to perform functional activities independently. By providing intention-controlled grip assistance during activity, Carbonhand addresses the gap between motor ability and functional performance, enabling patients to engage in meaningful tasks at home, at work, and in the community.

Who can benefit from Carbonhand – and who can't?

Carbonhand is beneficial for patients who:

Have reduced grip strength and/or limited hand endurance
Retain voluntary ability to initiate grasp and release
Experience functional limitations in activities of daily living (ADL), work, or leisure tasks
Have conditions such as:
- Stroke or other acquired brain injury
- Multiple sclerosis
- Spinal cord injury (incomplete)
- Neuromuscular diseases
- Orthopedic hand or upper-limb conditions
- Age-related hand weakness
Are motivated to use an assistive device in everyday life and can follow basic instructions

Carbonhand is generally not beneficial for patients who:

Lack the ability to initiate voluntary finger flexion
Have complete paralysis of the hand
Have severe joint contractures or deformities that prevent proper fitting

It is always the individual's conditions and needs that determine whether Carbonhand is appropriate. Contact Us to find out if Carbonhand would be beneficial for your patient.

What improves for the patient in real life?

Carbonhand is designed to improve functional performance in real-world activities, not just grip strength in isolation. By providing intention-controlled assistance during grasp, the device enables:

Ability to perform ADLs independently
Increased task endurance
Reduced need for compensatory movements
Reduced fatigue and overuse of proximal joints

Many patients are able to re-engage in meaningful activities at home, at work, and in leisure contexts that were previously difficult or impossible due to limited hand strength or endurance.

Meet some Carbonhand users

Hundreds of people have been helped by Carbonhand to regain independence and perform daily activities that would have been impossible without Carbonhand. Below are a few examples of the difference Carbonhand can make.

Terry suffered nerve damage during military service, watch him try Carbonhand.

John has inclusion body myositis, watch him try Carbonhand for the first time.

Effat had a stroke 3 years ago, now trying Carbonhand for the first time.
