The game “Parkour Fever” is based on active movement. The patient’s task is to control the character to move to higher platforms. On the left side of the screen, there is a bar depicting the lower limb position within the full range of motion, along with a marked threshold. When the patient moves the lower limb upward and crosses the threshold, a line appears indicating the character’s jump path. When the patient moves the lower limb down and the indicator goes below the threshold, the character jumps. The game ends after the timer expires.
