Chronic back strain occurs because of the sustained trauma and wearing out of the back muscles. [1] Acute back strain can occur following a single instance of over stressing of back muscles, as in lifting a heavy object. Chronic back strain is more common than the acute type. To avoid back strain it is important to bend the knees whenever you ...
A spasm is a sudden involuntary contraction of a muscle, [1] a group of muscles, or a hollow organ, such as the bladder. A spasmodic muscle contraction may be caused by many medical conditions, including dystonia. Most commonly, it is a muscle cramp which is accompanied by a sudden burst of pain.

Eperisone (formulated as the eperisone hydrochloride salt) is an antispasmodic drug.. Eperisone acts by relaxing both skeletal muscles and vascular smooth muscles, and demonstrates a variety of effects such as reduction of myotonia, improvement of circulation, and suppression of the pain reflex.
Applicable conditions include acute back [8] or neck pain, or pain after an injury. Long-term use of muscle relaxants in such cases is poorly supported. [8] Spasm may also be seen in movement disorders featuring spasticity in neurologic conditions such as cerebral palsy, multiple sclerosis, and spinal cord disease. Medications are commonly used ...

Any of these muscles can be involved or spasm with a painful and dysfunctional sacroiliac joint. [ 1 ] [ 8 ] [ 2 ] [ 3 ] [ 19 ] [ 12 ] The SI joint is a pain-sensitive structure richly innervated by a combination of unmyelinated free nerve endings and the posterior primary rami of spinal segments L2-S3.
The spasms can also affect the facial muscles, resulting in an appearance called risus sardonicus. Chest, neck, back, abdominal muscles, and buttocks may be affected. Back muscle spasms often cause arching, called opisthotonus. Sometimes, the spasms affect muscles utilized during inhalation and exhalation, which can lead to breathing problems. [10]
