Objective To explore the effect of sensory integration training on the development level of gross motor movements and balance ability in children with motor developmental delay. Methods This study was a prospective randomized controlled trial. A total of 88 children aged 3 to 6 years with motor developmental delay admitted to Handan Maternal and Child Health Hospital from May to November 2024 were included and randomly divided into the control group (n=44) and the experimental group (n=44) using a simple random number table. The control group received conventional motor training, while the experimental group received sensory integration training in addition to the conventional training. The children were evaluated before and after the intervention using the Sensory Integration Rating Scale, Test of Gross Motor Development-3 (TGMD-3), and the Berg Balance Scale (BBS). Statistical analysis was performed using independent samples t-test, paired samples t-test, rank sum test and χ2 test. Results After intervention, the sensory integration score of the experimental group was (46.35±5.24) points, which was higher than (35.29±7.30) points in the control group, and the difference was statistically significant (P<0.001).
After intervention, the scores of mobility skills (one-footed jump, forward slide step, standing long jump)
in the experimental group were 3 (2, 4) points, 1 (1, 2) points, and 1 (0, 2) points, respectively; the scores of ball control skills (ball bouncing in place, hitting a fixed ball, ground ball rolling) were 1 (1, 3) points, 2 (2,3) points, and 2 (1, 4) points, respectively, with a total score of 24 (17, 26) points. The corresponding scores in the control group were 2 (1, 2) points, 0 (0, 1) points,0 (0, 1) points, 0 (0, 1) points,1 (1, 2) points, 1 (1,2) points, and 20 (12, 22) points. All indexes in the experimental group were higher than those in the control group, and the difference were statistically significant (all P<0.05). After intervention, the scores of static balance, dynamic balance and total score in the experimental group were (26.73±1.25) points, (14.24±3.73) points and (42.51±5.86) points, respectively, which were higher than (21.66±2.04) points, (12.77±2.14) points and (38.99±6.13) points in the control group, and the differences were all statistically significant (all P<0.05). Conclusion Sensory integration training can benefit children with motor developmental delay by improving their sensory integration ability and positively influencing the development level of gross motor skills and balance ability.
