A Study of the Combination of Electrical Stimulation and Dysport® in Myofascial Pain Syndrome.

July 25, 2019 updated by: Ipsen

A 16-week Prospective Randomised Double-blind Study on Facilitation of DYSPORT® Effect on Myofascial Pain Syndrome (MPS) by Electrical Stimulation.

The purpose of this study is to determine whether electrical stimulation enhances the effect of botulinum toxin type A (Dysport®) on myofascial pain syndrome.

Description

Inclusion Criteria:

  • Chronic neck and shoulder pain for at least 6 months, refractory with other conservative treatments
  • Presents at baseline with pain score greater than 50mm on 100mm length VAS. Pain score will be measured as overall pain over the 7 days preceding the visit during activities
  • Active trigger point (TrP) defined as a tender spot localised in a taut band of muscle fibres associated with tenderness AND referred pain recognised by the patient into well-defined areas that are remote from the TrP area at palpation AND preferably local twitch response at palpation AND/OR jump sign at palpation

Exclusion Criteria:

  • Disc/bone disease
  • History of surgery on neck
  • Neurological deficits, neuromuscular junction disorder, Motor Neuron disease
  • Patient has received anesthetic injections to the target trigger point within 4 weeks of study enrolment, or corticosteroid injections within 3 months
  • Systemic inflammatory disease
  • Hypersensitivity to Dysport®
  • Diffuse tender points, or diagnosed with fibromyalgia
  • Previous electrical stimulation
  • Previous injection of Dysport® within 6 months of study enrolment

Primary Outcome Measures

Outcome Measure
Time Frame
Changes in mean pain measured by Visual Analogue Scale (VAS) will be assessed.
Time Frame: Comparison of VAS will be performed before Dysport® injection and at 16 weeks after injection
Comparison of VAS will be performed before Dysport® injection and at 16 weeks after injection
Number of patients in percentage whose pain intensity measured by VAS decreases to less than 50% of baseline.
Time Frame: Before Dysport® injection and at 16 weeks after injection
Before Dysport® injection and at 16 weeks after injection

Secondary Outcome Measures

Outcome Measure
Time Frame
Pain threshold measured by pressure algometer.
Time Frame: At each visit
At each visit
Neck Pain and Disability scale (NPAD) and Global Assessment of Impairment Scale (GAS) will be assessed.
Time Frame: At each visit
At each visit
