A limb stiffening device made of a length of tough, pliable and flexible material, preferably plastic, of open lattice pattern, having a continuous edge with radiused corners. The edge and the webs defining the open lattice pattern are substantially curvilinear in cross section. Fasteners are attached at opposite ends of the length of material for holding the length of material wrapped in the form of a sleeve around a limb, with the ends overlapped. The material is preferably provided with a pre-set bow tending to curl the length of material for facilitating wrapping around a limb, especially when a single hand is used for placing or removing the stiffening device, for example about the elbow of a golfer for preventing the golfer from bending his arm at the elbow while hitting a ball with a golf club.

A new and improved golfer's elbow stiffener apparatus includes a stiff continuous tubular assembly which is supported by and which encompasses a user's elbow, an upper portion of a user's arm adjacent to and above the elbow, and a lower portion of the user's arm adjacent to and below the elbow. The continuous tubular assembly includes a first side edge and a second side edge. A flaccid closure assembly is connected to the continuous tubular assembly and is adapted to secure the continuous tubular assembly to the user's elbow and adjacent arm portions. The continuous tubular assembly may be made from substantially inflexible material. Alternatively, the stiff continuous tubular assembly is capable of being flexed outward and inward longitudinally for placement around the user's elbow and adjacent arm portions. An inner liner assembly may be attached to an interior surface of the continuous tubular assembly. The inner liner assembly is made from a cloth material. The flaccid closure assembly includes a first flaccid portion connected to the first side edge of the continuous tubular assembly and extending distally therefrom. A second flaccid portion which is continuous with the first flacid portion is connected to the second side edge of the continuous tubular assembly and extends distally therefrom. A first hook-and-loop connector is connected to the first flaccid portion, and a complementary second hook-and-loop connector is connected to the second flaccid portion. A transverse cross-section of the continuous tubular assembly extends greater than 180 angular degrees.

A golf club swing teaching aid is provided having an elongated inflatable tubular sleeve adapted to be worn by the golfer to restrain bending of the golfer's leading arm during backswing. An alarm assembly which emits an audible signal is mounted on the sleeve for alerting the golfer that his or her leading alarm has been allowed to bend to an undesirable extent during backswing of the golf club. Means is provided for adjustably mounting the alarm actuating components of the alarm assembly on the sleeve so that the golfer may select the degree of bending of his or her leading arm that may take place during backswing of a golf club before the audible alarm is sounded. Selective adjustment by the golfer of the degree of adjustment of the sleeve also has an effect on the timing of the audible alarm. The audible alarm is initiated upon normal bending of the leading arm during swing follow-through thus alerting the golfer to the fact that he or she can now allow their eyes to leave the ball impact zone and focus on the ball flight path. The sleeve has a non-inflated area at the arm crease which allows substantially unimpeded arm bending at the elbow during follow-through so that the golfer is not restrained from executing a normal technique throughout the swing.

A reversible hand splint having utility in connection with either the left or right hands of stroke patients. A generally cane handle-shaped, pear or egg-shaped base member is fixedly secured to the end of an elongate flat base-supporting member that is covered on both sides with a hook and loop type of fastening material. A cradle for a forearm has a complemental strip of the same type of fastening material so that the base member is easily inverted when the splint is changed from one hand to another. Elongate straps having their forwardmost ends secured to opposite ends of the egg-shaped base member are wrapped in crisscrossing relation to one another to retain the patient's forearm in the splint.

A training aid for developing muscle memory in a golfer's leading hand for improving the ability to make chip and pitch shots has a hand-restricting wall which overlies the back of the golfer's hand and wrist. The wall has a lenthwise hinge which permits proper fitting. A pair of straps extending around the hand and wrist maintain the device in place.
