This study will quantify the muscle function after breast reconstruction using a minimally invasive latissimus dorsi flap. The proposed measures (clinical, isokinetic, electrophysiology, function and quality of life questionnaires) allow a precise, multidisciplinary, objective evaluation of the capacity of the latissimus dorsi muscle before surgery, 3 months, 6 months and 12 months after surgery. A function deficit is expected (decreased moment of adduction and internal rotation) 3 months after surgery and a return to the preoperative state 6 months and 12 months after surgery.

Before the surgery, patient will be completed two questionnaire DASH and BREAST-Q. Two tests will be performed (isokinetic test and EMG). After the surgery, at one month : 2 Questionnaires (DASH / BREAST-Q) will be performed At three months, six months and 12 months: 2 questionnaires + two tests will be perfomed

Measurement of the muscular moment
Measurement of the muscular moment of shoulder adduction preoperatively and at 3 months on an isokinetic dynamometer (Biodex®, New York, USA) at an adduction speed of 60 degrees per second during a maximal voluntary contraction
Time frame: During the 12 months post operation
Evaluation of muscle moments
Evaluation of muscle moments, isokinetic measurements, performed on an isokinetic dynamometer (Biodex®, New York, USA) at different speeds (isometric, 30, 60 and 120 degrees per second) of adduction and internal rotation after flap surgery minimally invasive latissimus dorsi (measurements before surgery, at 3, 6 and 12 months)
Time frame: During the 12 months post operation
Comparison of muscular moments
Comparison of muscular moments on the operated and "healthy" sides at 3 months, 6 months and 12 months. Perfomed on an isokinetic dynamometer (Biodex®, New York, USA) at different speeds (isometric, 30, 60 and 120 degrees per second) of adduction and internal rotation after flap surgery minimally invasive latissimus dorsi
Time frame: During the 12 months post operation
Calculation of adduction deficit
Calculation of adduction deficit is defined as a relative difference of more than 5% compared to the measurement taken preoperatively. Patients who completed at least one physiotherapy session post-surgery and before 3 months will be compared to the others.
Time frame: During the 12 months post operation
Measurement of surface electromyographic activity
Measurement of surface electromyographic activity (sEMG) of the latissimus dorsi, teres major and pectoralis major muscles is measured before surgery, 3 months, 6 months and 12 months post-surgery
Time frame: During the 12 months post operation
Functional clinical impact and quality of life
Functional clinical impact and quality of life is evaluated by DASH questionnaire. These questionnaire will be administrated before surgery, 1 month, 3 months, 6 months and 12 months post-surgery. The DASH self-questionnaire is an upper limb function assessment scale. It offers the ability to perform 23 activities, the severity of the symptoms and optional sports or instrumental and professional activity.
Time frame: During the 12 months post operation
Functional clinical impact and quality of life
Functional clinical impact and quality of life is evaluated by BREAST-Q questionnaire. These questionnaire will be administrated before surgery, 1 month, 3 months, 6 months and 12 months post-surgery. The BREAST-Q questionnaire is a self-administered quality of life questionnaire assessing satisfaction after breast reconstruction.
Time frame: During the 12 months post operation
