I dislike this type of research. It is all about compensation, NOT RECOVERY.
Mechanical Design of a Modular Gripper for Rehabilitation of Stroke Patients with Hemiplegia
All Authors
Abstract:
Although
the success rate of clinical rescue of stroke patients has greatly
increased with the advancement of medical technology, the number of
patients with stroke sequelae has increased. Traditional Chinese massage
therapy can improve the local blood circulation of affected limbs,
promote the metabolism of muscle tissues, help maintaining muscle
tension and prevent muscle atrophy. However, improper massage techniques
and strength may lead to paralyzed limb spasm and myositis ossificans.
In addition, long-term massage may cause occupational injuries to
nurses. Robotic technology has achieved good results in the field of
medical rehabilitation surgery. In this paper, with the soft robotic
technology, the end gripper of a mechanical arm was designed. Based on
the working principle of the crank slider mechanism, the opening-closing
part of the gripper was designed to be composed of a linear cylinder
and a two-sectional rigid arc structure. Soft pneumatic actuators with a
high expansion ratio were distributed and arranged in the inner walls.
Massage therapy was implemented by activating different pneumatic
actuators and adjusting the inflation pressure and the gripper was in
the soft contact with the body. The designed gripper is compliant and
safe and has the broad application prospect.
