Study summary

Chemotherapy, hormone therapy and radiotherapy used in the treatment of breast cancer try to prevent the recurrence of cancer. In addition to the benefits of radiotherapy, such as a decrease in recurrence and an increase in long-term survival, it may have side effects that may affect the well-being and daily life activities of patients. One of the treatment modalities used to cope with treatment-related side effects is myofascial release exercises. Myofascial release exercises can help reduce adhesions caused by scar tissue and fibrosis caused by radiation. In the literature, there is no study investigating the effect of myofascial release exercises on pectoralis major muscle viscoelastic structure. For this purpose, our study aims to investigate the effect of myofascial release exercises performed in addition to home exercise programme on pectoralis major muscle viscoelastic structure, pain, range of motion and shoulder functionality.

What researchers measure

Primary outcomes

  1. Tone - pectoralis major

    Myoton® PRO (Myoton Ltd, Myoton AS, Estonia) device will be used to objectively evaluate the measurement of Pectoralis Major muscle tone of the patients who will participate in the study. Myoton® PRO is a portable digital device that measures the tone with an objective and noninvasive method. A constant pre-pressure (0.18 N) is applied to the skin surface to compress the subcutaneous superficial tissues. The tension state of the tissue that characterized by the natural oscillation frequency; Hz.

    Time frame: 6 weeks

  2. Range of motion

    Shoulder range of motion will be evaluated by digital goniometer. Shoulder flexion degree, shoulder extension degree, abduction and adduction degree, internal rotation and external rotation degree will be assessed with digital goniometer. The results will be recorded in degrees.

    Time frame: 6 weeks

Secondary outcomes

  1. Pain - Visual Analogue Scale

    Visual Analogue Scale is one of the simple and common methods used in pain assessment. Self reported pain intensity during the rest and the activity measured by 0-10 centimeter chart. Visual Analogue Scale (VAS), where 0 indicates no pain or best and 10 indicates the most intense pain imaginable or worst. The patient will mark the severity of the pain on a 10 cm long chart

    Time frame: 6 weeks

  2. Shoulder Pain and Disability Index- SPADI

    Shoulder Pain and Disability Index: The Shoulder Pain and Disability Index (SPADI) is used to assess the pain and disability of individuals during certain activities. The SPADI is an assessment method consisting of two sub-headings, pain and functional status, which are completed in approximately 5-10 minutes. The first part consists of 5 questions to assess the level of pain during lying down, lying on the affected side and pushing activities. The second part consisting of 8 questions evaluates the functional status by questioning dressing, personal care and carrying activities. The subjects answer each question using a 10 cm Visual Analogue Scale. The answers to the questions are calculated as percentiles. The total score varies between 0-130, with the higher percentile indicating increased disability.

    Time frame: 6 weeks

  3. Quality of Life- Functional Assessment of Cancer Therapy-Breast" (FACT-B)

    It is designed to evaluate the quality of life in breast cancer patients from multiple perspectives. Its validity and reliability have been demonstrated. It consists of 5 subscales that assess quality of life as physical condition (7 questions), social life and family status (7 questions), emotional status (6 questions), activity status (7 questions), and other breast cancer-specific concerns (9 questions). The survey has 5-point likert scoring (0=not at all, 1=a little, 2=a little, 3=quite a lot, 4=a lot) . The total score is calculated by summing the subscale scores. A higher score on the questionnaire indicates a higher quality of life

    Time frame: 6 weeks
