In this study, the investigators will compare effects of two types of 8-weeklong interventions: a) multimodal or b) general movement to facilitate social communication and motor skills of school-age children with Autism Spectrum Disorder (ASD). Recently, the investigators have identified cortical dysfunction patterns as markers of imitation/interpersonal synchrony difficulties in children with ASD using functional near-infrared spectroscopy. In this project, the investigators want to validate whether cortical markers can determine treatment responders and if such markers are sensitive to training-related changes. Following training, the investigators expect to see a variety of behavioral and neural changes in both groups. If the study aims are achieved, the investigators will validate the use of cortical markers as a treatment response measure. This research will build evidence for the use of various movement interventions for school-age children with ASD.
46 children with ASD between 5 and 15 years of age will be randomly assigned to the multimodal or general play or seated play groups. Each child will participate in 9 testing sessions (4 pretests, 3 posttests, and 3, 2-month follow-ups) and 8 weeks of multimodal or general intervention between pre-tests and post-tests. In the 8-week phase between the pre- and post-tests, each child will complete group-specific intervention-related activities with the expert clinician twice per week via telehealth or face-to-face interactions. Each session will last for around 1-1.5 hours. If the study aims are achieved, the investigators will validate the use of cortical markers as a treatment response measure. Findings from this research will offer evidence for the use of various movement interventions to promote motor, social communication, and cognitive skills in school-age children with ASD.

Multimodal intervention will involve hello songs, warm up mainly involve sensory and stretching games, music time involves playing instruments, moving game involves use of music or songs to move the whole body, yoga involves themes/songs to perform yoga poses, and good bye involves a goodbye song and reflections about the session. In all movement conditions, trainers emphasize complex and multilimb coordination (asymmetrical and ipsi/contralateral movements) and balance.
The general exercise group will begin with hello games/set up and end with reflections and cleanup. Children will engage in limb and body warmup routines, specific strengthening exercises (single-joint/single-limb/symmetrical), moderate intensity endurance exercises involving various obstacle courses, and a cool down routine.
The seated play group will also begin with hello/icebreaker games and end with goodbye and cleanup. In between, they will read books and review the story line and overall message and engage in fine-motor activities involving building supplies and art-craft.

Bruininks-Oseretsky Test of Motor Proficiency-Second Edition (BOT-2)
The 3 gross motor coordination and 1 fine manual control composite of the Bruininks-Oseretsky Test of Motor Proficiency-Second Edition (BOT-2) were administered as a measure of gross and fine motor coordination at each time point. BOT-2 standard scores will be reported for each composite: (i) body coordination composite comprises of balance and bilateral coordination, (ii) the strength/agility composite is comprised of running speed and agility, (iii) upper-limb coordination composite is comprised of upper-limb coordination and manual dexterity, and (iv) the fine manual control composite is comprised of fine motor precision and integration. Standard composite scores on the BOT-2 have a Mean=50 and a standard deviation (SD)=10 for body coordination, strength \& agility, manual coordination and fine motor coordination composite domains. Higher standard scores represent a better outcome. Note there are no T-scores as such for BOT-2; the term often used is a standard BOT composite score.

Praxis Subtests of the Sensory Integration and Praxis Testing (SIPT) - Postural Praxis Error
The praxis subtests of Sensory Integration and Praxis Testing (SIPT) are standardized and normed measures of examining motor coordination, sensory integration, and praxis. Specifically, the investigators are planning to use items from subtest of postural praxis subtest. The praxis subtests will examine a child's ability to generalize the imitation skills to novel actions involved in the SIPT postural praxis subtest. This test provides the number of errors per action copied and a total number of errors. There is no fixed range as such but the scores could range from 0 to 100. There are no T or standard scores available for this subtest. Higher number of errors indicates a poor outcome.
Time frame: Baseline to Post-test after 8 weeks of intervention, Baseline to Follow-up testing after 8 weeks from post-test
Flanker Task of Executive Functioning (EF)
In the EF task data will be collected. Children will completed the response inhibition task using the Flanker test. This involves making decisions about where a group of fish shown on the screen are looking (right or left). Reaction time in msec were calculated for each response and averaged across trials. Lower values of reaction times indicate faster or better responses.
Time frame: Baseline to Post-test after 8 weeks of intervention, Baseline to Follow-up testing after 8 weeks from post-test
Synchrony Errors During the Rhythmic Synchrony Task
In the rhythmic synchrony task children will perform social drumming (i.e., move in synchrony with an adult as the child follows the adult's drumming motions). Synchrony errors were coded when the child was not matching with the adult for each movement cycle. Higher number of errors indicate a poor outcome. This was an experimental paradigm, and not a standardize measure. Hence, there are no T-scores to report.
Time frame: Baseline to Post-test after 8 weeks of intervention, Baseline to Follow-up testing after 8 weeks from post-test
Number of Prosocial Behaviors
In a structured play task, the tester assessed a child's ability to engage in prosocial behaviors across multiple helping bids to engage the child in helping behaviors (e.g., clean up of pennies, peg, blocks, cards, and dropped pencils). There are no T or standard scores available for this behavioral measure (not a standardized test). Higher number indicates more prosocial behaviors by the child during the helping bids.
Time frame: Baseline to Post-test after 8 weeks of intervention, Baseline to Follow-up testing after 8 weeks from post-test
2-Minute Walk Test
Testers will use the 2-minute walk test to assess endurance of the participating children. The test will be chosen based on the walking tolerance of the child and the severity of locomotor impairments. The test assesses the maximum distance that the child can cover in 1 or 2 minutes. The 2-minute walk test distance has been found to be highly correlated with the gold standard 6-minute walk test commonly used to assess endurance. This test provides a distance measure and more the distance covered indicates better performance. The distance covered may range from 125-200 meters approximately. There are no T or standard scores available for this functional measure. Higher distance covered number indicates a better outcome.

Timed-Up & Go Test (TUG)
The Timed-Up \& Go test (TUG) measures the time taken in seconds to stand up from a chair with armrest, walk 3 meters, turn around, walk back to the chair, and sit down again. A higher value indicates poor performance and time taken is usually between 4 to 7 seconds. There are no T or standard scores available for this functional measure. Lower value of time taken indicates better outcome.

Developmental Coordination Disorder-Questionnaire
Motor coordination questionnaire provides a total score of motor performance. For Children Ages 5 years 0 months to 7 years 11 months, a score between 15 to 46 is an indication of DCD or suspect DCD and a score between 47 to 75 is probably not DCD. For Children Ages 8 years 0 months to 9 years 11 months, a score of 15 to 55 is an indication of DCD or suspect DCD and a score between 56 to 75 is probably not DCD. For Children Ages 10 years 0 months to 15 years, a score of 15 to 57 is an indication of DCD or suspect DCD and a score between 58 to 75 is probably not DCD. Higher number indicates better motor performance. There are no other T-scores associated with this measure.
Time frame: Baseline to Post-test after 8 weeks of intervention, Baseline to Follow-up testing after 8 weeks from post-test
Sensory Processing Measure (SPM)
Sensory Processing Measure (SPM) measures assesses challenges with social participation as well as sensory challenges. A standard T-score of 60-70 indicates some problems and a range of 70-80 indicates definite problems. Note the SPM T-score has a mean of 50 and a standard deviation (SD) of 10. Note a higher T-score indicates greater sensory processing problems.
