Jumping for people with disabilities is dangerous even in adulthood. Yes, they can be spectacular, but they carry a high physiological load, so I advise you to use them very carefully in your training.
For jumps, the following are important: a developed joint-ligamentous apparatus, good mobility of the ankle, no problems with the spine, vestibular and proprioreceptive system, good development of the muscles of the lower leg, thighs, buttocks, cortex muscles, as well as the ability to bend the knees and coordinate the work of the arms and legs.
To teach a child to jump (if we are talking from the point of view of biomechanics), you need to:
1. Determine the functional state of the ODE, the state of muscle tone.
2. Determine whether the child needs to jump with his type of self-stimulation, if the child has them.
3. Evaluate the jump technique during testing (in three phases).
4. Remember that there are summing up (preparatory) exercises in the training.
It is important to take into account the limitations in jumping - excess weight, problems with the feet, joints, instability of the cervical region, posture disorders, intracranial pressure, EPI-activity, connective tissue dysplasia.
Therefore, we first study the recommendations from the orthopedist and neurologist, evaluate the child's ODE and behavior, and then build a program.
The exercises leading up to the jumps are:
1. Walking
2. Oversteps
3. Walking and descending from the platform
4. Extension and flexion of the legs while sitting and lying down
5. Crawling, climbing
When you have "built a base", with a confident one, then we learn to jump.
