- Brief Summary
The aim of this study is to determine the effectiveness of a multimodal physiotherapy intervention including scapula exercises in addition to deep dry needling and neurodynamic techniques versus scapula exercises only versus conventional shoulder exercises on pain intensity, perceived disability, scapula muscle activity and health-related quality of life.
- Detailed Description
Introduction: chronic shoulder pain is a frequent consequence after breast cancer treatment with a reported prevalence of 25% to 60% and is commonly termed "Persistent Pain after Breast Cancer Treatment" (PPBCT). Frequently, PPBCT includes neuropathic pain due to damage of neural tissue during surgery. However, recent studies, consider that myofascial pain syndrome and heightened mechanosensitivity of neural tissue can be also present in this women. Although PPBCT is typically managed with pharmacological treatment,currently, physiotherapy is presented as an alternative method. Physiotherapy in relation to the shoulder, commonly, focuses its treatment with therapeutic exercise. In this sense, there is great controversy about which are the most appropriate exercises. Recent authors, bet for more precise and analytical exercises in relation with scapula and reject conventional exercises for the shoulder. Taking into account each of the sources of pain presented by these women and the benefits of therapeutic exercise, it would be interesting to study which approach of physiotherapy treatment would be more appropriate in these women.
Subjects and methods: A randomized clinical trial, the examiner being blinded unaware of the intervention group to which subjects were assigned. Participants will be randomly assigned to three groups:
An experimental group, where the participants will be treated with Multimodal Physiotherapy;
Another experimental group where will be realized Scapular Exercises only;
And a third group where will be done Shoulder Conventional Exercises.
Pre- intervention, immediate post-intervention, 3, and 6 months assessments will be made. The selection criteria will be: women with peripheral persistent pain following breast cancer treatment (surgery and/or radiotherapy and/or chemotherapy) with pain for at least 6 months. The participants must understand and sign freely Informed Consent.
Sample size: 30 women for each group.
Data Analysis: A descriptive analysis of all variables will be performed. It will be established for all cases a confidence level of 95% (p \<0.05). The effectiveness will be assessed by comparing the experienced change of the three goups in outcome variables between physicaltherapy examinations.

Group Intervention Description Shoulder Conventional Exercises Therapeutic Education The protocol consists in: * Flexibility and Strengthening Exercises of the shoulder muscles conventionally performed in shoulder pathology treatment. * Therapeutic Education about chronic shoulder pain. The treatment duration is 1 day per week during 6 weeks. Multimodal Physiotherapy Scapular exercises The protocol consists in: * Dry Needling in active myofascial trigger points. * Neurodynamic techniques. * Scapular exercises. * Therapeutic Education about chronic shoulder pain. The treatment duration is 1 day per week during 6 weeks.

- Primary Outcome Measures
Name Time Method Pain Intensity Change from baseline VAS at after 9 physical therapy sessions, 3 and 6 months after baseline assessments will be require Visual analogue scale (VAS).100 mm horizontal with pain descriptors marked "no pain" on the left side or "worst imaginable pain".
- Secondary Outcome Measures
Name Time Method Health-related quality of life At baseline, after 9 physical therapy sessions, 3 and 6 months after baseline assessments were required. Questionnaire: Assessment of Cancer Therapy-Breast (FACT-B) Spanish version 4
Pain and Disability At baseline, after 9 physical therapy sessions, 3 and 6 months after baseline assessments were required. The questionnaire Shoulder Pain and Disability Index validated in Spanish, to measure the intensity and information on the characteristics of pain and the level of shoulder disability is used. This questionnaire contains a numerical scale from 0 to 10 to collect each answer.
Root-Mean-Square (RMS) EMG Amplitude At baseline, after 9 physical therapy sessions, 3 and 6 months after baseline assessments were required. Quantification of motor unit recruitment (electrical activity), by analyzing the RMS, expressed in microvolts (normalized data expressed as a percentage) of the muscles: upper and lower trapezius, middle deltoid, infraspinatus and serratus anterior during Abduction Movement
Onset EMG At baseline, after 9 physical therapy sessions, 3 and 6 months after baseline assessments were required. Beginning of motor activation, expressed in seconds (s), of the muscles: upper and lower trapezius, middle deltoid, infraspinatus and serratus anterior during Abduction Movement.
Myofascial Pain Syndrome. Active myofascial trigger points of the muscles involved in shoulder. Travell and Simon's Criteria were used. At baseline, after 9 physical therapy sessions, 3 and 6 months after baseline assessments were required. Travell and Simon's Criteria consists in (Wolfe et al 1992):
The major criteria include:
1. A patient's regional pain complaint;
2. Palpation of a trigger point elicits a stereotypic zone of referred pain specific to that muscle;
3. Identification of a palpable taut band;
4. As well as a palpable, and exquisitely tender spot along the length of that taut band;
5. Some degree of restricted range of motion of the involved muscle.
Three minor criteria have been suggested to further aid in the diagnosis of myofascial pain syndrome:
1. Palpation of a trigger point should reproduce the clinical pain complaint;
2. A local twitch response may be elicited by transverse snapping or needling of the trigger point;
3. The alleviation of pain by trigger point inactivation.
