Design outcomes

Primary

Measure	Time frame
The primary objective of this study is to analyse the difference in functional outcome, measured by the Constant Murley Scale at midterm follow-up, after treatment with high-energy ESWT versus ultrasound-guided needling in patients with symptomatic calcific tendinitis of the rotator cuff.	—

Secondary

Measure	Time frame
* VAS (pain) scale * VAS (satisfaction) scale * Patient reported change in symptoms (7 point likert scale) * Disability of the Arm Shoulder and Hand (DASH) score * The presence or resorption of the calcific deposits on conventional radiography of the shoulder * Work-ability score questionnaire	—
