Clinical Trial: Referred Pain Patterns Infraspinatus Muscle

Study Status: Completed
Recruit Status: Completed
Study Type: Interventional

Official Title: Referred Pain Patterns in Trigger Point 2 of the Infraspinatus Muscle in Patients With Shoulder Pain

Brief Summary: The first aim of the study will be to identify the most common ReP pattern and compare its coincidence with that described by Travell and Simons. Second, the study aim will be to verify whether there are any significant differences by sex and types of technique used in regard to the ReP pattern of TrP 2 of the infraspinatus muscle, an area described as more sensitive.Finally, the third aim of the study will be to determine whether deep dry needling will evoke the LTR and ReP more easily than manual palpation.

Detailed Summary: Patients will be recruited from a university's employee and student population by advertising at the university. Patients with shoulder complaints (described as pain felt in the shoulder or upper arm) will be randomly assigned to either an manual palpation or deep dry needling group. Participants will be randomly divided into 2 groups, a deep dry needling group and manual palpation group. Visual analogue scale (VAS), referred pain (ReP) pattern and features of referred pain of the infraspinatus muscle will be all assessed post-technique.

Current Primary Outcome: Mapping of Referred Pain Pattern [ Time Frame: One month ]

The participants from both groups will ask to report whether ReP is evoked and to describe the ReP pattern using an anatomical map of the upper half of the human body divided into eighteen areas. Nine areas corresponded to the anterior part of the body and the other nine to the posterior part of the body.


Original Primary Outcome: Same as current

Current Secondary Outcome:

  • Prevalence active trigger point [ Time Frame: One month ]
    Active trigger point is considered: Soreness taut band and familiar pain.
  • Evocation of Local Twitch Response [ Time Frame: One month ]
    These were assigned a numerical value of 0 (yes) or 1 (no) for better statistical handling of the data.
  • Subjective pain intensity: Visual Analogue Scale (VAS) [ Time Frame: One month ]
    The VAS for pain measures the amount of pain experienced by a subject on a continuum from 0 to 10, with 0 being no pain and 10 maximum pain.


Original Secondary Outcome: Same as current
