Individually adjustable hand exoskeleton for restoring hand functionalities


This hand exoskeleton allows the hand to regain its moving ability, e.g. in paralysis after a stroke. Thanks to its modular design, the exoskeleton can be individually adapted to the conditions of the patient. It is compatible with various sensor inputs, easy to put on and particularly comfortable to wear due to its low weight.


Limited ability to use the hands due to muscle weakness, loss of muscle strength, apraxia or ataxias, spasticity or other motor skills disorders are symptoms of different diseases, including strokes. This often has a negative impact on the patient’s professional and private life. The restoration of the hand functionalities is therefore crucial in order to improve the quality of life of those affected.


Hand orthoses are mainly used for the therapy of impaired and paralyzed hands in order to maintain remaining functionalities or to restore the ability to grasp and hold things, for example. Glove systems with motorized pull/push systems also offer additional functionalities, such as opening and closing the hand or moving individual fingers.
However, such motor-assisted solutions are usually not suitable for everyday use. It is often necessary to create bulky superstructures for pressure tanks and compressors or to provide additional external modules, which must then be attached to wheelchairs, for example. Stroke patients may also have hands and fingers bent by spasms, making it difficult or even impossible for them to put on such a glove.


As part of a project funded by the Baden-Württemberg Stiftung gGmbH, scientists from the Institute of Industrial Manufacturing and Management (IFF) at the University of Stuttgart have developed a hand exoskeleton that can be used to restore the gripping ability of a paralysed hand. The hand exo­skeleton consists of a central assembly unit and in­dividual, movable finger modules, which can be ad­justed to the specific conditions of the hand (such as finger shape and length). The exoskeleton is compatible with a large number of sensor inputs (such as EEG, EOG or EMG). Therefore, it can be tailor-made to meet the user’s specific needs. In addition, the patient can easily put on the exoskeleton without additional help, making it the ideal daily companion. The lightweight exoskeleton is also comfortable to wear.
