We normally explain them to the patient with this example to make it easier to understand: if you've never gone to a gym or done exercise and start to do weightlifting, for example, it is likely that it will be a waste of time. You need to start with a personal trainer who improves your muscle strength, then you can 'go it alone'. It is a similar scenario with these exercises: the synoptophore will help us to gain a good level of strength, then we can do them at home. If we start with therapy at home alone, it will not be enough to improve the little muscle strength.
