Active upper limb exercises will be conducted (flexion-extension and adduction-abduction) of large joints (shoulder, elbow and wrist) Associated with upper limb exercises, patients will undergo a series of exercises ergometer with lower limb (LL). The mobilization will be conduct on a cycle ergometer in an active, lasting 20 minutes, divided into three steps: heat 5 minutes; 10 minutes of low-intensity exercise, with a speed of 30 revolutions per minute (rpm); and 5 minutes recovery. The patient remains in the supine position with the head of the bed elevated to 45 degrees, while the lower limbs will remain planned

Sub-maximal test evaluates the aerobic endurance. The 6-minute walk test (6MWT) assesses distance walked over 6 minutes as a sub-maximal test of aerobic capacity/endurance.

Evaluate the fear of movement during activity ,17 items a self-reporting questionnaire based on evaluation of fear of movement, fear of physical activity, and fear avoidance. Individual item scores range from 1-4, with the negatively worded items (4,8,12,16) having a reverse scoring (4-1). The 17 item TSK total scores range from 17 to 68 where the lowest 17 means no or negligible kinesiophobia, and the higher scores indicate an increasing degree of kinesiophobia. Changes will be measured at baseline and at completion of 4th week
