Flow diagram showing the sequence of randomization, blinding, treatments, data collection, and analysis. TENS = transcutaneous electrical nerve stimulation; TPRF = transcutaneous pulse radiofrequency; CMS = Constant–Murley Shoulder score; PEG = pain, P (scored by visual analog score “VAS,” scored from 0 to 100), enjoyment of life, E (scored from 0 to 100), and general activity, G (scored from 0 to 100).
