Background: Children's motor skills are inversely related to sedentary screen time. COVID-19-lockdown during the pandemic has caused a further increasing on screening time. Aim: The current research aims at investigating the impact of Stickygym games on motor development of children. Materials and Methods: Twenty-eight eligible subjects (4-6 years old) were chosen and randomly grouped into control group (n=13) and experimental group (n=15). Using TGMD-2 test, gross motor development was measured. The experimental group performed online Stickygym games for 8 weeks. Stickygym kit includes Hook & Loop strips, with two linear polyester strips being easily but firmly attached together. Trained instructors performed online training sessions. In the end, TGMD-2 test was conducted again in person. Data analysis was done using Shapiro-Wilk, Levene and the analysis of covariance tests were with the significance level of 0.05 in SPSS 24. Results : Some locomotion skills were significantly improved by Stickygym games: bound ( P =0.005), galloping ( P =0.012), and running ( P =0.003), as well as object control skills: overhand throw ( P =0.004), underhand roll ( P =0.01), and striking a stationary ball ( P =0.021). Conclusion : This play kit can be utilized by pre-school educators and parents for improving object control and locomotion skills in preschool children.

Background: flatfoot is a common deformity characterized by the midfoot arch collapses during walking. As the midfoot is responsible for shock absorption, persons with flatfoot experience increased risk of injuries Aim: to the purpose of this study was to compare some motor-physical factors, lower extremity performance and stability index in male adolescents 10-12 having structural flat foot with and without insole. Materials and Methods: Subjects who utilized medical insoles for four to six months were selected in access from technical orthopedic in Karaj. After parents got aware of the purpose and conditions participating in research, their height and weight were measured. In the first day, they were assessed by motor-physical factors test (agility, speed, endurance), lower extremity performance (one-leg jump, cross jump, maximum distance access, walking six meters) and stability index wearing insole and on the next day without wearing insole. To analyze data, paired t-test was utilized. Wilcoxson was used respectively for parametric and non-parametric data. Results : According to the paired t-test a significant difference was observed in the 6-meter timed test. Mean difference was slower in wearing insole compared to not wearing insole. Moreover, stability index results showed more stability when not wearing insole which eyes were closed to significant. Conclusion: According to the results, wearing insole in individuals with flat foot, could slow down the walking speed. However, wearing insole may improve stability index when visual input is not in access.
