Further study details as provided by Ipsen:

Primary Outcome Measures:

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 ]
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:

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

Estimated Enrollment:	68
Study Start Date:	April 2005

Eligibility

Ages Eligible for Study:	21 Years and older
Genders Eligible for Study:	Both
Accepts Healthy Volunteers:	No

Criteria

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
