The lumbar girth is a necessary protective support for the acute phase of lumbar disc herniation. Choose a lumbar brace with rigid support in order to protect the affected area by supporting and limiting the lumbar movement. Note: Acute short-term applications are necessary and effective, while long-term dependence can cause muscle dysfunction and atrophy, which may aggravate lumbar instability. Care must be taken when wearing the lumbar girth that the lower edge of the girth is fixed to the sacrum in order to conduct pressure to provide support and limit lumbar spine activity well.
