The present invention is directed to a physical therapy device capable of folding into a single portable device comprising a frame comprising a first lengthwise bar and a second lengthwise bar; and a first transverse bar and a second transverse bar. The frame is configured to be adjusted between an unfolded configuration for use and a folded configuration for storage; a first set of stanchions, each coupled to at least a portion of the first lengthwise bar; and a first handrail coupled to a top portion of each of the first set of stanchions. In the folded configuration, the first lengthwise bar is parallel to the second lengthwise bar, and the first and second transverse bars are configured to hinge such that each bar folds towards a center region of the frame to be substantially parallel to the first and second lengthwise bars.

A display method for outputting a result of scoring for a performance of a scoring competition, the display method includes obtaining input information regarding to the scoring competition, obtaining a recognition result of a plurality of elements included in the performance, determining a difficulty level of each of the plurality of elements based on the recognition result and a first rule, limiting a target to be used for the scoring to a part of the plurality of elements according to the difficulty level of each of the plurality of elements, and outputting a scoring screen that includes a first display area displaying the plurality of elements and the difficulty level, a second display area for an aggregate result, third display area for a score of the performance directed to the limited part of the elements, and a fourth display area for a 3D model of the athlete.
