. Data are presented as mean + standard deviation. TPRF = transcutaneous pulsed radiofrequency; TENS = transcutaneous electrical nerve stimulation; n = number of the patients; ASA = American Society of Anesthesiologists physical status; CMS = Constant–Murley Shoulder score; PEG = pain, enjoyment of life, and general activity.
