Abstract

OBJECTIVE:

Magnetic therapy has been used in the treatment of a wide variety of chronic pain syndromes. It has not been studied in the treatment of myofascial shoulder pain in persons with spinal cord injury (SCI). Because this type of pain is commonly refractory to traditional therapy, alternative treatments often are considered. The primary objective is to determine whether myofascial shoulder pain in persons with SCI can be temporarily ameliorated with static magnetic fields.

DESIGN:

Case series.

SETTING:

Clinic of a university hospital system.

PARTICIPANTS:

A volunteer sample of 8 participants with SCI; 3 women, 5 men; mean age = 45 years; mean duration of injury = 12.3 years.

INTERVENTIONS:

Placement of a commercially available magnet with a static magnetic field of 500 gauss on the affected shoulder for 1 hour.

MAIN OUTCOME MEASURES:

Pretreatment and posttreatment scores on the short-form McGill Pain Questionnaire and pressure algometry were compared.

RESULTS:

The short-form McGill Pain Questionnaire descriptors demonstrated significant decreases: stabbing, 0.75 +/- 0.71 (P < 0.02); sharp, 0.50 +/- 0.53 (P < 0.033); and tender, 0.88 +/- 0.83 (P < 0.021). They also demonstrated a significant decrease in the present pain intensity of 0.63 +/- 0.52 (P < 0.011). Participants demonstrated a nonsignificant decrease of 0.813 +/- 0.998 (P < 0.55) on the visual analog scale. Pressure algometry was nonsignificant with a difference of 0.062 +/- 1.17 (P < 0.885).

CONCLUSION:

Static magnetic fields may decrease the sensory dimensions and intensity of myofascial shoulder pain in persons with SCI.
