Clinical Trial Summary

Breast cancer is the most frequent cancer type in women globally. In conjunction with the new developments, breast cancer survival has increased therefore the management of long-term complications has gained importance. Breast cancer survivors can face the loss of muscle strength, increased fatigue and diminished physical function associated with treatment-related long term effects and psychological affection and thereby reduced quality of life. Upper extremity lymphedema or breast cancer-related lymphedema (BCRL) is one of the most prominent long term complications which affects breast cancer survivors in many ways after breast cancer surgery. It has been reported that breast cancer survivors with BCRL have the lower muscle strength and more activity limitations when compared to the ones free of BCRL. In BCRL, affected extremity has been found to 36% more weaker when compared to the unaffected side. Fatigue is one of the most prominent symptoms when considering cancer-related symptoms in cancer survivors. It has been stated that increased fatigue is correlated with increased activity limitation and deterioration in physical function. The hand-grip test which is frequently used in the assessment of decreased muscle function has been stated as a reliable and repeatable test in breast cancer survivors. In addition, this test is frequently applicable to assess mortality, physical and functional capacity, symptoms after surgery and to designate an exercise program. There are studies that investigate upper extremity function associated with hang-grip strength in breast cancer survivors. Yet, there is a lack of the objective result or conclusion of the BCRL effect on upper extremity function which is assessed with hang-grip strength when compared without BCRL. Therefore, this study is planned to investigate of cumulative effects of factors such as lymphedema severity, age, fatigue, body mass index, muscle strength, physical activity level, pain level, exercise benefits/barriers scale score on hand-grip strength related upper extremity functionality in breast cancer survivors.

Outcome

Type Measure Description Time frame Safety issue
Primary Hand-Grip Strength Handgrip strength will be assessed with LaFayette Professional Hand Dynamometer, Model 5030L1, LaFayette Instruments, NY, USA). The standard position which can be achieved by 90-degree elbow flexion, shoulder abducted, and hand mid-prone positioned; 90-degree shoulder abduction and 90-degree shoulder abduction positions will be used to assess hang-grip strength. Three measurements will be requested and the maximum value of them will be recorded. 1 minute resting period will be provided between the positions at which handgrip is assessed. 15 minutes
Secondary Tissue Dielectric Constant Measurement: Sub-tissue fluid proportion will be evaluated via Moisture Meter D (Delfin Technologies, Kuopio, Finland) on both upper extremity (right and left) in predefined reference points on volar side (6 cm distal and 8 cm proximal points from cubital crease, 10 cm inferior side point from axilla and dorsal point of web space in the hand) by using four different probes which can assess 0.5 mm, 1.5 mm, 2.5 mm and 5.0 mm depth. Values taken by 2.5 mm depth probe will be used to calculate the ratio (affected side TDC value/Unaffected side TDC value) to stage lymphedema severity along with the International Society of Lymphology staging system. 30 minutes
Secondary Muscle strength Participants' muscle strength of shoulder flexion, abduction, and elbow flexion will be assessed via Handheld digital dynamometer (Lafayette Manual Muscle Tester, Model 01165, LaFayette Instruments, NY, USA). Both upper extremities will be assessed three times and the average value will be recorded. 1 minute resting period will be provided between the positions at which muscle strength is assessed. 10 minutes
Secondary Pain Threshold Measurement The sensitive pain threshold and normal pain threshold will be evaluated by a digital algometer (Wagner FDIX, Greenwich, USA) on reference points as follows: C5-C6 zygapophyseal joints' lateral points, upper trapezius (proximal, middle and distal lateral points, length measured by a tape from C7 Processus spinosus to acromion and this length will be divided equally into three parts for proximal, middle and distal lateral point), deltoid muscle (crista deltoidea), dorsum of the webspace. Measurements will te took both for right and left upper extremity. Units will be recorded as kgf. 8 minutes
Secondary International Physical Activity Questionnaire-Short Form (IPAQ-SF) This scale was intended to be filled to assess participants' physical activity levels within the last seven days. Then, MET calculations will be done via a basic Excel Spreadsheet which is pre-defined MET values formulated inside. Scale data then obtained according to the participants' answers and recorded. 3 minutes
Secondary Fatigue Impact Scale This scale has 9 items that can be answered as "Strongly Disagree" through "Strongly Agree" by numbered as 1 and 7, respectively. Then total points will be calculated and divided into 9 to achieve the Fatigue Impact Scale score. The higher points will be indicated more perceived fatigue, while lower points indicate less. 3 minutes
Secondary Disabilities of Arm, Shoulder and Hand Scale (DASH) DASH has 30 items related to upper extremity function. Participants will be requested to grade some expressions related to the function within a 5-point Likert scale as follows: "No difficulty: 1, Mild Difficulty:2, Moderate Difficulty: 3, Severe Difficulty: 4 and Unable to perform: 5). The symptom score of the DASH will be calculated as dividing filled items total score to filled items' number and minus one from this data then multiplying with 25. The higher points indicate a deteriorated shoulder and hand function while lower points indicate a better upper extremity function. 10 minutes
Secondary Exercise Benefits/ Barriers Scale Exercise Benefits/Barriers Scale has 43 items each can be graded within a four-point Likert type scale. Barrier items are reverse coded. 43 items are all related to exercise and exercise beliefs in both in the aspect of health and general. Strongly disagree, disagree, agree, strongly agree will be scored as 1,2,3,4 or vice versa whether the item should de reversely coded, respectively. Total scores ranged between 29 and 172. The barrier scale score is ranged between 14 and 56. The benefits scale is also ranged between 29 and 116. The higher the score of Barriers scale, the greater the perception of barriers to exercise. 20 minutes
