A handle for sport equipment comprises a tubular body (7) which extends along a longitudinal axis (L) and has an outer peripheral surface (8) adapted to be grasped by a user and shaped with a plurality of longitudinal faces (9) placed side by side in correspondence of edges (10) adapted to facilitate the positioning of the finger joints of the gripping hand by the user. The edges (10) are arranged along at least one pair of helical or spiral paths that develop around said longitudinal axis (L) with mutually opposite sign to subdivide each of said longitudinal faces (9) into a plurality of areas or flat surfaces (11) sized to accommodate a corresponding phalanx of the gripping hand of the user, each of said areas or flat surfaces (11) being perimetrically delimited by at least one pair of edges (10, 10) of each of the helical or spiral paths.

A batting aid to be worn on a thumb of a distal hand of a baseball player while gripping a handle of a baseball bat. The batting aid includes a thumb ring to secure the batting aid to the thumb, and a cushioning saddle integrated with the thumb ring. The saddle has a crest portion configured to engage a portion of the index finger of the distal hand, also having at least one resiliently deformable flap configured to extend substantially along a middle portion of the metacarpal bone of the index finger. The batting aid minimizes the transmission of vibration and impact from the bat hitting a ball, thereby reducing pain and injury. The batting aid conforms to the bat handle and improves a player's grip on the bat. Because the resiliently deformable flap is self-aligning on the player's hand, the player can more easily concentrate on hitting pitched balls.

Devices systems and methods are disclosed. Among other things, the devices systems and methods can facilitate ergonomic gripping of a handle; conform to the shape of a wrist; enhance golf techniques or performance; enhance racket sport technique or performance; protect a head of a user engaged in contact sports or other hazardous activities; identify concussions, in some cases in substantially real time; provide sterilization of garments; control surgical robots; allow for medical treatment of multiple subjects without disrobing; provide biometric or other data; and/or be used to train muscles or body parts for, for example, performing specified tasks using a body part.

A rotational assistive device includes a first end portion configured for operable connection with a user, and a second end portion configured for operable connection with an implement utilized via a swinging motion. A main body portion extends between the first end portion and the second end portion. The main body portion includes a plurality of telescoping leg portions, such that when the implement and rotational assistive device are swung, the main body portion moves between a closed position having a closed length and an extended position having an extended length greater than the closed length.

An improved putter grip is provided. In one embodiment, the putter grip includes an enlarged heel portion that can be held in the fore-to-aft direction or the side-to-side direction, dependent upon the user's preference. The putter grip includes a front-facing surface between a right side surface and a left side surface. The putter grip also includes a rear-facing surface that is opposite of the front-facing surface. The rear-facing surface includes an upper portion, defining the enlarged heel, a lower portion, and an intermediate portion. The lower portion of the rear-facing surface is spaced apart from the front-facing surface by a reduced distance, and the intermediate portion is a continuous extension of the lower portion. As a result, the front-to-back width of the putter grip is greater in the upper portion than in the lower portion, with the intermediate portion defining a slightly concave exterior curvature.

A table tennis paddle or like table tennis racket designed so the player can us the expert shake hands serve grip for the entire game. The present invention features a handle that comfortably fits into the cavity formed by the three fingers behind the handle of the conventional paddle when the expert player serves. This serve grip allows the player to rotate his wrist during the forehand stroke imparting more spin to the ball, more easily use the wrist rotation in the backhand stroke, and to play the entire game with the serve grip, thus not changing his grip during the entire game.
