Effects of Selected Exercise Program on Microcirculation and Lymphedema in Postmastectomy Patients

Study Overview
=================
Brief Summary
-----------------
PURPOSE: to assess the efficacy of Qigong exercise on microcirculation in postmastectomy lymphedema patient. BACKGROUND: Qigong is a mind-body integrative exercise originating from traditional Chinese medicine and is used to improve health and energy levels through regular training, yet its effects are not empirically assessed. Qigong may be a potentially beneficial exercise for survivors of breast cancer and could be used to regulate upper limb blood flow and decrease lymphedema. There is lack in knowledge and information in published studies about the efficacy of Qigong exercise on microcirculation in postmastectomy lymphedema patient. So, this study will be designed to provide a guideline about the efficacy of Qigong exercise on microcirculation in postmastectomy lymphedema patient. HYPOTHESES: It will be hypothesized that: It was hypothesized that Qigong exercise has no or limited effect in microcirculation in postmastectomy lymphedema patient. RESEARCH QUESTION: Does Qigong exercise an effect on microcirculation in postmastectomy lymphedema patient?

Detailed Description
-----------------
Measurement procedure: Both methods of measurements will be done before the beginning of the treatment (pre-treatment) then at the end of the study after 2 months of treatment (post treatment) for both groups of the study. A-Upper Limb Circumference by manual goniometer B- LASER Doppler Imaging: Treatment procedures: In this study the treatment protocol was presented in the form of an exercise program lasted for 60 minutes, twice weekly for 8 weeks postmastectomy and achieved under the following phases: Warming up phase: The main aim of this phase was to get the muscles warm and loose for strength training. The subject has to train for ten minutes aerobic exercise at a mild velocity before the beginning of each exercise session. Warming up helps direct needed blood flow to the muscles and prepares the body for exercise. Warming up is important for preventing injury as well as gaining maximal benefit from the exercise, because loose and warm muscles respond better to the challenge of the program. Exercise phase: Participants in the experimental group were qigong practitioners. The qigong style they learned is known as 18 Forms Tai Chi Internal Qigong, which is quite popular among Chinese breast cancer patients. It is a kind of physical and mental exercise (internal qigong) that focuses on relaxation, deep breathing, and slow and coordinated movements and uses the mind to guide these movements. There are a total of 18 upper and lower body movements, and all of the techniques are performed while either standing or semi squatting. Qigong practice session was initiated immediately and continued for about 6 minutes. Each participant in the qigong group performed 18 Forms Tai Chi Internal Qigong once and was assessed immediately afterward in sitting (to measure the vascular outcomes) and lying (to measure the upper limb circumference) positions. The control participants were given no specific exercise instruction after the baseline assessment. Instead, they were asked to rest (sit quietly in the laboratory) for 6 minutes and then participated in the post assessment directly

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| microcirculation of blood cells | As these blood cells are moving, the reflected light is subject to the Doppler shift, which is a small change in frequency. When laser light penetrates the tissue under study it is scattered and partly absorbed. Some of the scattered light returns to the tissue surface, where it is registered by a photo detector inside the instrument. This signal is then processed to extract information about the microcirculatory blood flow. According to the Doppler principle, light particles which hit moving blood cells undergo a change in wavelength/frequency (a Doppler shift), while light particles which encounter static structures return unchanged. The perfusion can be calculated since the magnitude and frequency distribution of the doppler shifted light are directly related to the number and velocity of blood cells but unrelated to their direction of movement. | changes from the baseline at 2 months after treatment | 
| Upper Limb Circumference | The circumferences of both arms that represented the participants' lymphedema status were taken at the level of (a) 10 cm proximal to the lateral epicondyle; (b) the elbow joint, right at the lateral epicondyle; (c) 10 cm distal to the lateral epicondyle; and (d) the wrist joint, just distal to the ulnar styloid process. The upper limb circumferences were measured with a cloth measuring tape. The difference in each circumference measurement between the ipsilateral and contralateral arms was calculated to detect a 2 cm between-side difference. | changes from the baseline at 2 months after treatment |
