Stroke
Problem: Man in his 60s who suffered a right-sided stroke a few years ago. Poor balance, difficulty in coordination of movement and difficulties keeping a firm grip with the left hand. Sensitivity in the same hand is impaired. This leads to an unreliable grip. He has lost the feeling for how hard he must grip in order not to lose an object placed in his hand at the same time he has no strength. He has relatively good grip if he is standing / sitting completely still and, for example, has to lift a cup. As soon as he must move an object from one place to another, his grip is much more unreliable. He has, therefore, difficulties to use his left hand in the everyday chores at home and is completely dependent on his wife.
He loves gardening, but as this often requires two hands, he is unable to do that since his stroke. It is hard to plant and take care of plants with one hand only.

Solution: He uses a SEM Glove™ on his left hand. Not many adjustments needed on the glove as it sits well on his hand.

Result: With the SEM Glove™, he has become more independent at home and does not have to ask his wife for help all the time. He can also work more in the garden again which, also affects his mental well-being highly.

Neuromuscular Disease
Problem: Woman in her 60s with neuromuscular disease (Charcot Marie Tooth).
Generally weak throughout the body but especially her hands. She has very poor grip. Right hand is the weakest so mostly her left hand is active. This weakness makes it difficult to perform common household chores involving gripping and lifting things. She needs both hands to lift a coffee cup. She is unable e.g. to lift a milk carton out of the fridge, lift washing detergent, dishes etc.

Solution: She gets a SEM Glove™ size Small for her left hand as this hand is strongest. Her right hand is too weak. The artificial tendons in the glove’s fingers are slightly shortened and the sensors are moved higher into the fingertip area.

Result: With the SEM Glove™ she is more independent at home. She does not have to ask for help with everything or wait for a family member to come by her home to take out a milk carton from the refrigerator, lift her coffee pot or a pan.
