In sports, the<unk>  (in gymnastics, lost move syndrome or the twisties) are a sudden and unexplained loss of ability to execute certain skills in experienced athletes. Symptoms of the<unk>  are losing fine motor skills and psychological issues that impact on the muscle memory and decision-making of athletes, leaving them unable to perform basic skills of their sport. Common treatments include clinical sport psychology therapy as well as refocusing attention on the underlying biomechanics of their physical actions. The impact varies widely. A<unk>  event may last a short time before the athlete regains their composure or it can require longer term adjustments to technique before recovery occurs. The worst cases are those where the athlete does not recover at all, forcing the player to abandon the sport at the highest level. Originally used to describe a sudden and inexplicable loss of the ability to putt correctly, the term has later been broadened to apply to any unexplained loss of skill, and has been applied to athletes in a wide variety of sports.
