Tying shoelaces is a real challenge for bionic hands because it requires significant dexterity. For a hand to truly play its part in this task, it should have good hand speed and the ability to switch grips with ease.
Ossur i-Limb
The i-Limb is one of the top-tier bionic hands both in terms of price and features. But we’re not that impressed with its role here. For more information, see our Ossur i-Limb.
Ottobock Michelangelo
The Michelangelo is widely considered the Cadillac of bionic hands and is likely the most expensive. It fairs a little better than the i-Limb but not enough to celebrate. For more information, see our Ottobock Michelangelo.
Taska Hand
The Taska Hand is a fairly recent entry into the bionic hand market. At almost half the price, it fairs no worse at tying shoelaces than its priciest competitors. For more information, see Taska Hand.
Ottobock beBionic
This video is a bit older than the others but demonstrates a similar technique. For more information, see Ottobock beBionic.
Vincent Evolution 3
This one is a bit of a different task than the others but still shows an over-reliance on the natural hand. For more information, see Vincent Evolution 3.
All it all, it looks as if bionic hands still have a ways to go before they can tie shoelaces with the same dexterity as natural hands.
