Table 1 Basic data of active and passive joint position senses (AJPS, PJPS) for internal and external rotation (IR and ER) and isokinetic parameters for 180° speed for the involved (I) and uninvolved (U) shoulders of 23 patients operated on for idiopathic frozen shoulder, with statistical data regarding the particular comparisons between them (Wilcoxon test; p <0.05)

From: Shoulder proprioception – lessons we learned from idiopathic frozen shoulder
