Effectiveness of Diacutaneous Fibrolysis in Painful Shoulder

Effectiveness of Diacutaneous Fibrolysis on Pain and Mobility in Patients Suffering From Painful Shoulder. A Randomized Pilot Study.

While Diacutaneous fibrolysis (DF) has achieved promising results empirically, its effectiveness has not been tested in clinical trials. The investigators hypothesized that the use of DF in patients suffering from painful shoulder would increase the active mobility and reduce the pain during movement. To test the hypothesis a double blind (patient and investigator) randomized clinical trial was carried out in two public Primary Health Care Centres. Fifty patients were randomly allocated to two groups: the intervention group, who received a real DF session, and the control group, who received a placebo DF session.

Study Overview

• Status: Completed
• Conditions: Shoulder Pain
• Intervention / Treatment: Other: Diacutaneous Fibrolysis; Other: Diacutaneous Fibrolysis (placebo)

Detailed Description

Background and objectives:

Diacutaneous fibrolysis (DF) is a manual technique to treat the mechanical pain of the musculoskeletal system. While this technique has achieved promising results empirically, its effectiveness has not been tested in clinical trials. We aimed at evaluating the effectiveness of a single session of DF on pain and mobility in patients suffering from painful shoulder.

Subjects and methods:

This clinical trial took place in two public Primary Health Care Centres. Fifty patients were randomly allocated to two groups: the intervention group, who received a real DF session, and the control group, who received a placebo DF session. The degree of active mobility (flexion, abduction, extension, external and internal rotation), the pain in the hand behind back position and the participant's perception of the technique in terms of comfort and results obtained were measured.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Intervention Group; The intervention group was treated with a single session of DF following the procedure as described by the authors.	Other: Diacutaneous Fibrolysis; The implementation of the technique consists of three consecutive stages: The first stage involves manual palpation, which is carried out by the hand that is not holding the hook, with the objective to find the area to be treated; the second, or instrumental palpation stage, is carried out by introducing the spatula of the hook together with the index finger of the palpatory hand to locate with precision the adherent connective fibers or fibrous corpuscles; the third, or fibrolysis stage, is the actual treatment. Here, a brief supplementary traction is carried out with the hook.; Other Names: Manual therapy
Placebo Comparator: Control Group; The control group was treated with a single placebo session of DF.	Other: Diacutaneous Fibrolysis (placebo); The placebo was designed for this study and the stages of manual and instrumental palpation occur strictly at a superficial level. In the third stage, instead of fibrolysis a pinch of skin is hold with the thumb of the palpatory hand and the tip of the spatula, so that the patient feels the hook distinctly but without any action taking place on the deep tissular planes.; Other Names: Manual therapy

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change in Active Flexion Movement After Intervention Minus Baseline	A universal double armed goniometer was used to measure change in active flexión movement in the sagital plane with the elbow fully extended and the forearm in indifferent pronosupination (thumb forward)	Baseline and the same day (just after intervention)
Change in Active Abduction Movement After Intervention Minus Baseline	A universal double armed goniometer was used to measure change in active abduction movement in the scapular plane with the elbow in extension and the forearm in supination	Baseline and the same day (just after intervention)
Change in Active extensión Movement After Intervention Minus Baseline	A universal double armed goniometer was used to measure change in active extensión movement in the sagital plane with the elbow fully extended and the forearm in indifferent pronosupination (thumb forward)	Baseline and the same day (just after intervention)
Change in Active External Rotation After Intervention Minus Baseline	A universal double armed goniometer was used to measure change in active external rotation measured in the neutral position of the shoulder (arm pinned to the trunk), elbow flexed to 90º and the forearm in indifferent pronosupination (thumb forward)	Baseline and the same day (just after intervention)
Change in Active Internal Rotation After Intervention Minus Baseline	Change in active internal rotation was measured with the hand behind back test. The position achieved by the tip of the thumb was marked and with a flexible metric tape (always the same) the distance in centimetres between this mark and the inferior tip of the spinous process of C7 was measured; the shorter the distance, the better the mobility	Baseline and the same day (just after intervention)

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change in Pain in the Hand Behind Back Position After Intervention Minus Baseline	An unmarked Visual Analogue Scale from 0 (no pain) to 100 (worst pain) millimeters was used. At baseline, participants registered the pain perceived in the position used to measure the internal rotation. After intervention, they registered the pain with the hand placed in the same position taking as a reference the mark in the first evaluation.	Baseline and the same day (just after intervention)
