This study is a case control pilot study to investigate the impact of a short-term intervention on training anticipatory postural adjustments in a population of people with neurodevelopmental disabilities.
Data will be collected by using a weighted pendulum to provide a posterior perturbation to test subjects' postural reactions pre and post-intervention. Intervention will include four sessions of weighted ball tosses/weighted tether ball stops to improve muscle activation patterns and efficiency. EMG sensors, 3D motion analysis, and force plates will be used to collect the necessary data.

Muscle activation timing
Evaluation in change in muscle activation timing of anterior tibialis, soleus, gastroc, rectus femoris, biceps femoris, rectus abdominis using electromyography
Time frame: Pre-intervention muscle activation timing will be assessed on the initial visit. Post-intervention muscle activation timing will be assessed immediately after the fourth training session, at most, 7 days later.
Muscle amplitude response
Evaluation in change in amplitude of anterior tibialis, soleus, gastroc, rectus femoris, biceps femoris, rectus abdominis using electromyography
Time frame: Pre-intervention muscle amplitude response will be assessed on the initial visit. Post-intervention muscle amplitude response will be assessed immediately after the fourth training session, at most, 7 days later.
