Intervention Details:
  • Biological: Botulinum toxin type A
    Other Name: AbobotulinumtoxinA (Dysport®)

Primary Outcome Measures :
  1. 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 ]
  2. 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 ]

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

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
