Effectiveness of Dry Needling as a Treatment of Shoulder Myofascial Pain Syndrome in Spinal Cord Injury Patients

Pressure Pain Thershold (algometry).

Baseline®dolorimeter - 22lb / 10kg, STOCK CODE: 12-1442 It will be measured with an algometer that is an instrument that provides quantitative / objective information on pain at a specific point, depending on the pressure on which it is applied. A circle is drawn around the trigger point on which the indelible marker test will be performed to confirm in the last measurement which is the exact point on which it is worked. 3 consecutive measurements are made at the same point, waiting between one and another measurement for a period between 30-60 seconds, and the average of the 3 measurements will be used as a statistical value.

Time frame: Change from baseline, immediately after intervention and one week later.

McGill Pain Questionnaire (Spanish version).

This scale consists of a set of 78 adjectives included in 20 groups (including 2 to 6 in each group) and that express a characteristic of pain. Within these 20 groups we find the Pain Rating Index (PRI) divided into: sensory (groups 1-10), affective (groups 11-15), evaluative (group 16) and miscellaneous (group 17-20) ), of which the patient can only choose one word from each of the 20 groups, choosing only those adjectives that best suit his pain sensation. It also includes a category on the changes that experimental pain, and another with a rate of pain intensity (Present Pain Index = PPI).

Time frame: Change from baseline and one week later.

Visual Analog Scale (VAS)

This scale is a line of 10 centimeters without marks between the parameters without pain and unbearable pain, where the patient has to mark between those parameters where his pain is.

Time frame: Change from baseline and one week later.

Shoulder Pain And Disability Index Spanish version (SPADIe).

It consists of a 10-item scale that assesses shoulder pain and the difficulties in activities of daily life that it generates, divided into two main sections: the first 4 items refer to the intensity of pain and the last 6 refer to the difficulty of carrying out specific activities. All the items have a minimum score of 0 and a maximum of 10, therefore the total score is between 0 and 100, with 0 being the best possible value in relation to pain and difficulty, and 100 being the highest value and so much more painful and disabling.

Time frame: Change from baseline and one week later.

Range Of Movement (ROM)

Objective will be to measure different ranges of movement of the affected upper limb (internal rotation and horizontal adduction) in question due to myofascial pain syndrome. In this case the movements that passively will be measured with a bubble inclinometer.

Time frame: Change from baseline, immediately after intervention and one week later.
