An exercise glove for intrinsic muscles and method of use. The exercise glove incorporates rigid ribs having rib distal end angles corresponding to patient metacarpal phalangeal joint angles. The ribs passively hold the patient metacarpal phalangeal joint angles in extension, while the patient actively flexes the proximal interphalangeal joints and distal interphalangeal joints to obtaining optimal intrinsic muscle stretching. The rib distal end angles may be set by a physical therapist to correspond to individual patient metacarpal phalangeal joint angles, or alternately an array of ribs of different rib distal end angles may be provided with the exercise glove, from which rib assortment the physical therapist may choose ribs having appropriate rib distal end angles ribs to attach to the exercise glove. The method includes the steps of using the exercise glove to passively hold metacarpal phalangeal joints in extension, while actively flexing proximal and distal interphalangeal joints.

A robotic gripping device allows for pinch and power grasps using interconnected phalanges with configurable connections. A distal phalange is rotatably connected to a proximal phalange. A contact phalange is rotatably connected to the proximal phalange. The contact phalange is rotatably connected to the distal phalange via a contact-distal pivot or rotation connection. In response to sufficient contact between the contact phalange and an object, the contact phalange is configured to rotate in a first direction toward the proximal phalange. The rotation of the contact phalange causes rotation of the distal phalange in a second direction toward the object. The contact-distal connection may be a configurable gear connection for adjusting the movement ratio of the contact and distal phalanges.

The invention relates to a fixing orthosis after the restoration of extensor tendon rupture, which is characterized in that: the fixing orthosis after the restoration of extensor tendon rupture is made of thermoplastic mounded plastic, and is divided into five parts: a front arm part, a hand back part, a proximal phalanx part, a middle phalanx part, and a distal phalanx part. Each part is provided with a fixing band and a woolen hasp, and an angle-adjusting hinge axis is arranged between two parts. During use, after the angles among the parts are adjusted by adjusting the hinge axes, the fixing orthosis can be fixed on the affected limb through the fixing band and the woolen hasp which are arranged on each part. The fixing orthosis has the following advantages that: the fixing orthosis can selectively fix corresponding joints, only fixes the joints of injured fingers and avoids the stiffness of normal finger joints; and after the operation, flexion angles of the fingers are gradually reduced by adjusting the hinge axes, and the defect that the fixing orthosis is always fixed at a strong flexion position after the operation is overcome.
