It depends on whether you are using IQoro to cure problems caused by neurological injury – like stroke, which has caused dysphagia or facial paralysis, or whether you are training because of a muscular weakness such as Hiatus hernia, snoring or apnoea.
If it is muscular weakness, then maintenance training will be required. Once you have achieved your desired result you should continue to train with a reduced number of sessions per day. You’ll need to find the right level for yourself.
