The SEM Glove™ is an active and intuitive aid that amplifies a reduced but existing function of the hand. This means that to use the SEM Glove™ to its full potential the user should have a slight hand function left to initiate the grip.



User criteria:

  • Some form of active flexion and extension (10 degrees). Not necessary that the user has to be able to actively stretch her/his fingers fully
  • Mild spasticity
  • No contractions that affect the user’s ability to grip an object
  • Cognitive level: possibility to understand the benefits of using the glove and the way it operates
  • Possibility to move the whole arm enough to fulfill the intended task


To have impaired strength and endurance in the hand is not unusual and can be found amongst a large group of patients. Within these groups, there is a huge variation when it comes to the level of remaining hand function. It is therefore vital to do an individual assessment of the patients remaining range of functions in order to see if the SEM Glove™ is suitable. Please do not hesitate to contact us, we are always at your disposal for guidance and discussion.

The SEM Glove™ is mostly used within the following patient groups:

Local arm and hand injuries
One of the reasons for weak hand or impaired hand function can be a damage locally in the arm or hand, both in the bones, muscles and/or nerves. Hand injuries can be very diverse. In cases where strength and/or endurance is impaired but some movement is still present our SEM Glove™ can help.

Rheumatic diseases

Most rheumatic diseases have in common that it is positive to exercise and to continue to use the affected hand. The level of strength assistance that can be set in the SEM Glove™ is to be discussed with the responsible physiotherapist or occupational therapist so that the user can train their muscles and get help to get over the initial resistance and possible pain.

Neurological injuries / diseases

There are many different injuries and diseases where the central and peripheral nerve system are affected and hence the symptoms include impaired strength and/or endurance. Some of these diseases also affect the strength and/or endurance of the hand. Examples are Carpal Tunnel Syndrome, MS and Parkinson.
Traumatic or congenital brain injury
Traumatic or congenital brain injury often cause among others symptoms of reduced mobility and strength in the arm and hand. The most common traumatic brain injury is a stroke. Depending on the degree of the remaining capacity of the hand, the SEM Glove™ can help compensate to a certain degree the impaired hand function.

Spinal cord injuries

Damage to the nerves in the spine can also affect the hands. Depending on the nature and level of injury the patient may have some movement in the arms and hands, but weakened strength and impaired hand function.

Temporarily impaired hand strength

Patients can be affected by a weak grip even for a short period in combination with certain diseases and injuries, for example, Carpal Tunnel Syndrome or caused by Borrelia.
