Persistent cognitive deficits in ACL-injured athletes despite of rehabilitation: an observational longitudinal study by Jesús Jiménez-Martínez, Jesús Jiménez-Martínez, Francisco Alarcón-López, Luis Javier Chirosa-Ríos, Luis Javier Chirosa-Ríos, Alejandro Gutiérrez-Capote, Alejandro Gutiérrez-Capote, David Cárdenas-Vélez, David Cárdenas-Vélez

“…Finally, ACL injury athletes did not reach a cognitive performance comparable to healthy athletes, for example on mean reaction time in the Flanker Task (BF₁₀ = 60.64) and the 3-ball tracking at speeds of 19.9 and 28.8 deg/s (BF₁₀ = 16.30, BF₁₀ = 12.12, respectively).ConclusionsACL injury athletes show improvements in cognitive performance post-surgery, but it stabilizes at the end of the rehabilitation and remains lower than that of athletes who did not suffer an ACL injury. …”

Tongue Muscle Training App for Middle-Aged and Older Adults Incorporating Flow-Based Gameplay: Design and Feasibility Pilot Study by Kuan-Chu Su, Ko-Chiu Wu, Kuei-Ru Chou, Chia-Hsu Huang

“…This pilot study used an image recognition system to detect the tongue movements of 32 healthy middle-aged and older adults (7 males, 21.9%; 25 females, 78.1%) during 3 game training tasks, each requiring different reaction speeds. Their physiological and psychological signals, as well as the results of the Flow State Scale 2 (FSS2) questionnaire, were used for correlation analysis regarding relevant flow experiences to establish and evaluate the feasibility of our method. …”
