Two different interventional approaches in the conservative care of radiculopathic low back pain were presented in a poster today at the 28th Annual Meeting of the American Academy of Pain Medicine.

Results from a small study showed that patients receiving interlaminar lumbar epidural steroid injections (LESI), by either the midline (MIL) approach or the parasagittal (PIL) approach had significant improvement in pain relief, quality of life and everyday functionality.

However, the PIL approach was more effective in targeting low back pain with radicular pain that was secondary to lumbar disk disease, compared to the MIL approach. Kenneth D. Candido, Chairman, Department of Anesthesiology, Advocate Illinois Masonic Medical Center, Chicago, and Professor of Clinical Anesthesiology at the University of Illinois Hospitals in Chicago reported these results.

A lumbar epidural steroid injection (LESI) is an elective procedure for pain control. “Despite limited evidence for efficacy and long-term improvement in pain and functionality of LESI, this is one of the most commonly performed interventional pain management procedures in the U.S.,” comments Dr. Candido.

The purpose of this study was to evaluate the effect of interlaminar LESI on the quality of life and everyday functionality and to compare the two different approaches, the midline (MIL) approach and the parasagittal interlaminar (PIL) approach.

The two most accepted types of treatments in the conservative care of low back pain with radiculopathy secondary to lumbar disk disease have been the midline approach and the transforminal technique, with the transforminal technique thought to be superior in terms of providing more effective pain relief and more superior analgesia.

However, beginning in 2004, Dr. Candido indicated that they began to hear of several cases where permanent paraplegia and paralysis were associated with the transforminal technique. “This technique does not rely on approaching the interlaminar space but approaches the spine from a lateral aspect where the nerve root foramen is found.

Paralysis occurs because the nerve root has a radicular artery, and if that artery is violated, the medication that is typically injected into the artery can cause an infarction of the spinal cord,” Dr. Candido stated. The parasagittal interlaminar approach was developed to maintain the safety of the midline approach, but enhance the analgesic efficacy of using interlaminar LESI.

In the parasagittal interlaminar approach, the needle is inserted towards the angled corner of the interlaminar space, unlike the midline approach in which the injection is made in the center of the space. If a patient is having right-sided pain, the needle will be inserted into the right corner, and in the left corner for left-sided pain.

After Institutional Review Board approval and written informed consent, 44 adult patients scheduled to undergo LESI for radicular low back pain were randomly assigned to one of two groups. The first group (22 patients) received LESI using the midline (MIL) approach, and the second group (22 patients) received LESI using the parasagittal interlaminar (PIL).

The patients ranged in age from 18 to 80 and had a history of unilateral lumbosacral radiculopathic pain and lumbar disk disease including disk herniations, bulging discs and degenerated discs, where at least 50 percent of the disk height was preserved respective to contiguous levels (based on MRI findings). All patients completed the Oswestry Low Back Pain Questionnaire before injection and on days 1, 7, and 28 after injections.

The Oswestry Questionnaire is designed to give information about how the patients’ back pain affects their ability to manage everyday life. Sections on impairments, such as pain, and abilities that include personal care, lifting, walking, sitting, standing, sleeping, social life, sex life and traveling are included as well.

The injections included 120 mg (2mL) of MPA (Methylprednisolone Acetate) + 1 mL of NSS (normal saline solution, sterile, no preservatives) + 1mL of Lidocaine 1%. The NRS (Numeric Pain Rating Scale) was recorded at rest and during movement 20 minutes before, and on days 1, 7, and 28 after the injection.

The results showed no difference in the basal Oswestry Low Back Pain Score between the PIL and MIL group (21.25+/-7.60 vs. 19.50+/-5.13). Both groups of patients had significant improvement in pain relief, quality of life and everyday functionality. The results showed that the PIL approach was more effective than the MIL approach in targeting low back pain with radicular pain secondary to lumbar disk disease. At day 28, the PIL group had an 11 on the Oswestry Scale, from a starting point of 22 (on a scale from 1 to 50, with 50 being severe pain).

This was not only a statistically significant result but also a clinically significant result. “If we can improve a patient’s overall daily function by about 50 percent and if this improvement can be persistent as it was in this study following a single injection for up to one month’s time, the parasagittal interlaminar approach is a viable alternative to midline injection techniques, and a potentially safer alternative to the transforminal approach,” Dr. Candido concludes.

While music is both soothing and entertaining, several studies have also shown that music therapy can help people who have illnesses, learning disabilities or emotional problems.

Music therapy is a technique that uses music to improve a person’s mental as well as their social function. There are four ways of using this technique: listening to music, dancing, singing or making musical improvisation using all types of instruments. The therapy has been found very useful for helping people who have a wide array of health problems.

Music for the elderly

One of the most important areas where this therapy is getting great results is with the elderly. In the 50+ age groups, people can withdraw themselves from an active life and lose interest in what surrounds them, which can decrease their self-esteem. Music can help these individuals feel better and to diminish negative feelings.

In some nursing homes, staff organize music therapy group sessions with the goal of making communication easier. They use the music as a stimulant. Depending on the objectives they want to achieve, the staff will use different types of songs. If they want to arouse emotions they will use songs that remind patients of moments from their past. These kind of songs favor the memory.

Other times they use melodic songs to stimulate physical activity. With all these techniques, the goal is to overcome physical problems derived from boredom, fear of death, personal stagnation or loneliness.

Music to fight off diseases

Music has been shown to diminish pain and reduce anxiety and stress. Some researchers have demonstrated that people who have practiced this therapy before surgery have suffered less pain than the ones who didn’t. This therapy has also had positive results with people who suffer Alzheimer’s and schizophrenia.

Other ways music can help 

Music therapy is also used on pregnant women for their labor preparation because this is an important relaxation factor. You can also obtain benefits through singing practice. In some music therapy sessions they encourage people to sing to show their personality and to improve their diction, their attention and memory.

Types of music 

The type of music you use will depend on the person and his or her personal situation. Melodies should go against the patients state of mind. Paradoxically, when feeling depressed, the patient shouldn’t listen to any upbeat, rhythm song because in that case that song won’t have the same effect or meaning.

Similar to the treatment of the elderly, songs shouldn’t be completely unfamiliar, otherwise they won’t pay attention to them. However songs shouldn’t be very popular either because it will have a negative effect as well. It is very important to be treated by a credible therapist. He or she will be the one that will know which is the perfect song for each patient.
