Brief Summary

Shoulder pain is one of the most common reasons people consult with their primary health care provider, and 40-50% of these patients with shoulder pain continued to complain of persistent symptoms after 6 to 12 months. It has been suggested that the presence of myofascial trigger points (MTrPs) may contribute to the chronicity of shoulder symptoms. An MTrP is a hyperirritable taut band of tissue within a muscle that produces pain when stimulated MTrPs are common in patients with shoulder disorders and occur most often in the infraspinatus muscle of a painful shoulder MTrPs were associated with an acidic biochemical environment with elevated levels of inflammatory mediators, neuropeptides, and proinflammatory cytokines such as bradykinin and calcitonin g-related peptide. It was hypothesized that metabolic demands on muscle and capillary constrictions may contribute to the development of MTrPs. To date, only a few studies have examined the vascular environment of MTrPs and surrounding areas before and after dry needling. No studies have yet examined whether dry needling would change blood flow in patients with shoulder pathology. Therefore, the purpose of this pilot study is to examine the effect of dry needling on blood flow of the infraspinatus muscle using color Doppler imaging in individuals with and without shoulder pain.

Outcome Measures

Primary Outcomes (4)

  • Peak Systolic Velocity (PSV)

    On a Doppler waveform, the PSV corresponds to each "peak" within the spectral window. These values will be used to calculate the RI with the formula RI = (PSV - EDV)/PSV.

    Change from baseline PSV immediately

  • End Diastolic Velocity (EDV)

    EDV corresponds to the point marked at the end of the cardiac cycle just prior to the systolic peak.

    Change from baseline EDV immediately

  • Resistive Index (RI)

    Resistive Index is used to assess the resistance in a pulsatile vascular system.The RI is defined by the the formula RI = (PSV - EDV)/PSV.

    Change from baseline RI immediately

  • Pulsatile Index (PI)

    Pulsatility index (PI) is defined as the difference between the peak systolic flow and minimum diastolic flow velocity, divided by the mean velocity recorded throughout the cardiac cycle. It is a non-invasive method of assessing vascular resistance with the use of Doppler ultrasonography. PI is defined with the formula PI = (PSV - EDV)/mean velocity, where mean velocity is the average flow velocity during the cardiac cycle.

    Change from baseline PI immediately

Secondary Outcomes (2)

  • Pain Pressure Thresholds

    Change from baseline Pain Pressure Threshold immediately

  • Shoulder Range of Motion

    Change from baseline shoulder range of motion immediately

Study Arms (1)

Individuals with and without Shoulder Pain

EXPERIMENTAL

Individuals with shoulder pain will receive dry needling to the two to four most tender points in the infraspinatus based on examiner palpation Individuals without shoulder pain will receive dry needling to two points in the muscle belly of the infraspinatus near the insertion and below the midpoint of the spine of the scapula

Other: Dry Needling

Interventions

A sterile, disposable, solid filament needle (Seirin Corp., Shizuoka, Japan) will be inserted manually into the MTrP of the infraspinatus muscles. Once the needle has been inserted, the technique described by Hong (1994) will be used. The needle will be pistoned in an up and down motion within the infraspinatus muscle at approximately 1Hz for 10 seconds with the aim of eliciting local twitch responses.

  • non-traumatic origin of pain
  • presence of at least one MTrP with referral pain pattern in the infraspinatus muscle determined through palpation.

You may not qualify if:

  • systemic joint disease (e.g. rheumatoid arthritis)
  • evidence of red flags (e.g. fracture, infection, tumor, cauda equina syndrome)
  • cancer
  • neurological disorders
  • neuropathy
  • Raynaud's disease
  • pregnancy
  • previous shoulder surgery
  • repeated infection
  • immunocompromised disease (e.g., diabetes mellitus, HIV, AIDS, lupus)
  • inability to maintain the testing and treatment positions (i.e., supine and prone-lying) for 15 minutes at a time.
