The present device relates to an apparatus and a method for allowing a golfer to properly grip a golf club. A proper grip is one that allows for the most efficient radial deviation (abduction) and ulnar deviation (adduction) as well as flexion and extension of the wrist of the golfer's upper hand, while also minimizing club head and shaft axis rotation during a golf swing. This grip can be achieved through the use of a marking system comprising the golfer's glove and the grip of the golf club. By matching one or more markings on the glove, placed in specific locations on its anterior, with one or more markings located on specific positions on a golf club grip, the proper location of the golfer's upper hand can be found and the proper grip can then be made.

A golf swing and putting stroke training device is provided that comprises a forearm connection strap, a pivoting member, and a connection means adapted to secure to a golfing glove closure strap. The device firmly secures to the forearm of the forward arm of a golfer, wherefrom a first member is supported therefrom extending toward the user's wrist. A second member is pivotably attached to the distal end of the first member and connects to the user's golfing glove along the top of the user's upper hand. The pivot joint therebetween allows for rotation of the second member in single plane and thus limits the user's wrist to single degree of freedom. Wrist movement is limited during a full swing to radial and ulnar deviation only, while the device is adapted to remain attached while putting to prevent wrist flexion or extension (e.g. wrist “breaking”) during a putting stroke.

A kit of components of a multi-functional group of hand/forearm exercise tools wherein each tool permits the user to strengthen one or more muscles associated with the hand/forearm of the user, and/or to increase radial and ulnar deviation and forearm pronation and supination, or permits the user to mimic a functional task, such as turning a door knob, opening a bottle cap, inserting and turning a key, turning and tightening a nut, and turning and tightening a bolt.

The invention relates to a lasso driving mechanism with two degrees of freedom. One end of a forearm part of the lasso driving mechanism is connected with a wrist elbow connector; one end of a wrist joint radial deviation/ulnar deviation moving part is hinged with a first mounting spindle head while the other end is connected with one end of a wrist joint flexion and extension moving part; a first encoder mounting rack and a first encoder are successively arranged on a second mounting spindle head from inside to outside; the first encoder mounting rack is hinged with the second mounting spindle head and is fixedly connected with a first wrist joint; the other end of the wrist joint flexion and extension moving part is hinged with a joint shaft; one end of a palm part is fixedly arranged on the joint shaft while the other end is connected with a palm support part; a second encoder is arranged on the joint shaft; the left ends of a first rope and a second rope are both fixedly arranged on a first output wheel while the right ends are fixed on the wrist joint radial deviation/ulnar deviation moving part; and the left ends of a third rope and a fourth rope are fixedly arranged on a second output wheel while the right ends are fixed on the palm part. The lasso driving mechanism with two degrees of freedom is used for auxiliary and rehabilitation training of the aged and the disabled.

The invention relates to a 2-SPU/RR parallel pneumatic wrist rehabilitation device. The device adopts a 2-SPU/RR parallel configuration, wherein the 2-SPU/RR parallel configuration mainly comprises two SPU branch chains, an RR branch chain, a forearm semi-ring, a base semi-ring, an arc-shaped supporting plate and supports; the SPU branch chains comprise ball pairs S, air cylinders and Hooke pairsU, and the RR branch chain comprises a flexion/extension semi-ring, a radial deviation/ulnar deviation semi-ring and a corresponding rotating shaft assembly. The lower portion of the base semi-ring isprovided with a bottom plate structure with a long-strip-shaped rectangular cross section, the forearm semi-ring is arranged on the bottom plate structure, and the front and rear ends of the base semi-ring are supported by the two supports together; the RR branch chain is arranged in the base semi-ring, the SPU branch chains connect the forearm semi-ring and the RR branch chain together, the arc-shaped supporting plate is arranged on the bottom plate structure of the base semi-ring, and the axes of the forearm semi-ring, arc-shaped supporting plate and base semi-ring coincide. The 2-SPU/RR parallel pneumatic wrist rehabilitation device has the advantages that the bearing capacity is strong, the structure is compact, the size is small, the range of motion is large, and all parts in contactwith the upper limbs of the human body adopt opening structures, thereby greatly improving the wearing convenience and comfort of patients.

The invention relates to the technical field of medical rehabilitation adjuvant therapy equipment, and particularly discloses a forearm fracture reduction hand clamping device. The device comprises abase mechanism, slide rail mechanisms and a palm clamping mechanism; the palm clamping mechanism is fixed to the slide rail mechanisms, the palm clamping mechanism and the slide rail mechanisms are entirely fixed to the base mechanism; the base mechanism comprises a base, a lifting sleeve whose height can be adjusted freely and a slide rail fixing seat; the lifting sleeve and the slide rail fixingseat are fixed to the base; the palm clamping mechanism comprises a thumb clamping part, a palm clamping part and an adjustment part; the thumb clamping part is connected with the palm clamping part;the adjustment part is used to make the palm clamping mechanism adapt to palms with different sizes; the slide rail mechanism comprise a transverse slide rail mechanism and a longitudinal slide railmechanism; the transverse slide rail mechanism is used to drive the palm clamping mechanism to move transversely, so that the fixation of ulnar deviation angle is realized; the longitudinal slide railmechanism is used to drive the palm clamping mechanism to move longitudinally, so that the fixation of the palm tilt angle is realized.

The invention discloses a distal radius fracture wrist fixation protection tool. The distal radius fracture wrist fixation protection tool comprises a fore arm binding mechanism, a TDOF (Two-Degree of Freedom) mechanism and a palm binding mechanism which are sequentially connected in a fore arm direction, wherein the fore arm binding mechanism comprises an upper clamping plate for fore arm fixation, a rear restraint strap for fore arm fixation and a lower clamping plate for fore arm fixation, the rear restraint strap for fore arm fixation is fixed to the upper clamping plate for fore arm fixation, and the lower clamping plate for fore arm fixation is connected with the upper clamping plate for fore arm fixation by virtue of the restraint strap; the palm binding mechanism comprises a hand back fixation clamping plate, a palm fixation restraint strap arranged on the hand back fixation clamping plate and a palm fixation clamping plate connected with the hand back fixation clamping plate through the restraint strap; the TDOF mechanism comprises a rotary joint pedestal connected with the upper clamping plate for fore arm fixation, an ulnar-deviation radial-deviation rotary joint connected with the hand back fixation clamping plate, and a palm-inclination back-extending rotary joint arranged between the rotary joint pedestal and the ulnar-deviation radial-deviation rotary joint. The distal radius fracture wrist fixation protection tool is capable of replacing gypsum, achieving an effect of fixing a wrist of a patient suffering from distal radius fracture, and improving certain defects of gypsum fixation.
