The goal of this observational study is to test the strength of the shoulder joint and elasticity of the deltoid muscle of the patients who had a reverse shoulder arthroplasty. The main questions are: • Whether there is a difference between the operated and healthy shoulders in terms of strength and deltoid elasticity of the patients. • Is there any correlation between the functional status, elasticity and strength of the operated shoulder? Participants will be asked to attend the isokinetic shoulder strength tests and shear wawe ultrasound elastography measurements. They will be also asked to fill the quick DASH and Constant score forms.
