A neck brace and / or neck collar is very suitable to support the neck where it is needed.
For example after a trauma such as a fall on the neck or after a collision (whiplash). However, extra support or protection is also required for a neck hernia to reduce the load on the nerve root.
A neck brace relieves the muscles
A neck collar gives decompression space to the nerve roots and gives firmness and protection around the neck so that movements are inhibited where necessary and the muscles are relieved.
A neck brace and / or neck collar has different heights and, in some cases, different hardnesses.
