A combined analysis of input data, EMG data, and video data can be used to evaluate miss-hits and hitting form. Until now, there was only data on whether the speed was fast or slow for rapid key hits. Video results demonstrated that some subjects hit in a flexible manner, while others hit with unnatural form. Matching input and surface EMG data revealed movement with muscle activity, but without an input, that is, a miss-hit. The results indicated that the input speed of a continuous single hit (6.48 Hz for 0–5 s) decreased over time (5.02 Hz for 25–30 s). Ten male subjects were asked to repeatedly hit the same key on a keyboard quickly using their left ring finger for 30 s. Therefore, in this study, we evaluate rapid key hits using a combination of input data, video data, and surface electromyography (EMG) for fingers that are not accustomed to moving rapidly. Numerous studies have focused on key hits however, those studies have primarily focused on speed. It is unknown whether such hits can be a burden on fingers or cause overuse injuries. Los resultados obtenidos ponen de relieve la alta validez concurrente del programa.Įsports players often use the fingers on their left hand to produce quick key hits on keyboards. Se encontraron correlaciones entre los pulsos de la modalidad clásica y versión movimiento y con algunas de las escalas de los cuestionarios utilizados como fue supresión emocional, ansiedad cognitiva y somática y, especialmente, autoconfianza. Se utilizaron dos versiones informáticas del FTT, junto a los cuestionarios Inventario del Estado de Ansiedad en Competición-2 (CSAI2), Cuestionario de Ansiedad Estado-Rasgo (STAI), Inventario de Situaciones y Respuestas de Ansiedad (ISRA), Inventario de Ansiedad Competitiva (SCAT) y Cuestionario de Regulación Emocional (ERQ). El 34’31% de la muestra fueron hombres y el 65’68% mujeres. Formaron parte del estudio 102 participantes, de los cuales 47 practicaban actividad físico-deportiva de forma habitual y 55 no. El objetivo de la presente investigación fue validar una versión informatizada del FTT, estimando su validez concurrente con pruebas estandarizadas de ansiedad y ansiedad precompetitiva. Įl Finger Tapping Test (FTT) es una prueba neurofisiológica con largo bagaje en el campo de la neuropsicología, utilizada para examinar el control motor. The pilot study indicated that the tapping rate does not change significantly after 30-s duration for a 2-min tapping. The tapping duration of 1 min per finger was determined based on the results of the pilot study performed prior to the actual study. The participant was seated in neutral sitting posture with keyboard at about elbow height while the thumb and bottom part of palm were supported and forearm unsupported. Immedi- ately after 1 min tapping for every finger, the participant was asked for his or her subjective rat- ing about the fatigue in the associated finger accord- ing to Borg's 10-point scale of ratings of perceived exertion (Borg, 1998). For instance, for left little finger, the participant typed on key A (on standard QWERTY layout) repetitively with his or her maximum voluntary tempo for 1 min. For each of the tapping tasks, the participant, using the corresponding finger, tapped the key in the standard position on the home row of a conventional keyboard for touch typing ( Figure 1). experimental task consisted of 1-min max- imum volitional tapping with each of eight fingers (excluding thumbs).
