The future of human movement control ?
Really interesting study: in-race cadence data from world 100K
champs. Fatigue matters less than expected;
A new study shows a majority (82%) of adolescent patients presenting with FAI syndrome can be managed nonoperatively, with significant improvements in outcome scores at a mean follow-up of two years: ow.ly/GXtC30n49nc pic.twitter.com/dyr4f6pEOU
" Rehabilitation of gait in PSP should also include oculomotor training because the ability to control eye movements is directly related to the control of gait and safe ambulation. Vision plays a critical role in the control of locomotion because it provides input for anticipatory reactions of the body in response to constraints of the environment. Anticipatory saccades occur normally in situations that involve changing the direction of walking17 or avoiding obstacles.18 When downward saccades are not frequently generated during obstacle avoidance tasks, there is an increase in the risk for falling. Di Fabio et al19 reported that elderly people at a high risk for falling generated fewer saccades than their low-risk counterparts during activities involving stepping over obstacles. In addition, foot clearance trajectories were asymmetric in the high-risk group, with the lag foot trajectory being significantly lower than the lead foot trajectory. Similar behavior has been observed in patients with PSP during stair-climbing activities. Di Fabio et al20 recently reported that patients with severe oculomotor limitations had a lower lag foot trajectory than those with mild oculomotor limitations. "
" The content of the eye movement program was as follows: First, a picture card was shown to the patient, and then mixed with 20 other cards and spread face up on the desk. The patient was instructed to find that one card. This task was repeated approximately 20 times. Second, the therapist moved a baton slowly while drawing curves and the patient was instructed to keep his or her gaze fixed on the tip of the baton. In this task, the distance between the baton and the patient was maintained at approximately 1 m and the task was performed for approximately five minutes. Third, the patient was instructed to shake his or her head laterally as quickly as possible and a letter card with letters written upside down was presented to the patient to read. This task was repeated approximately 10 times. Fourth, the therapist moved a baton slowly from a point approximately 5 cm away from the patient to a point approximately 50 cm away and the patient was instructed to keep his or her eyes on the baton. This task was performed for approximately five minutes. The experimental group underwent eye movement training while the control group underwent gait training for 20 minutes per session, five times per week for six months in total."
