Background: Frozen shoulder is a condition of the shoulder joint that experiences inflammation, pain, adhesions, atrophy
and shortening of the joint capsule resulting in limited motion. In frozen shoulder patients, the limited range of motion of
the shoulder joint can affect and reduce functional ability. This study aims to analyze the correlation between the limited
area of motion of the shoulder joint with the functional ability of frozen shoulder patients at the Medical Rehabilitation
Installation Dr. Mohammad Hoesin Palembang. Methods: This study was an observational analytic study, correlation
test, with a cross sectional design. There were 29 frozen shoulder patients who met the inclusion criteria in the Medical
Rehabilitation Installation Dr. Mohammad Hoesin Palembang in November 2018 was taken as a sample using consecutive
sampling techniques. Functional ability was assessed using the quickDASH questionnaire and the area of motion was
measured using a goniometer, then analyzed. Results: The results of the correlation test showed significant results
between functional abilities and the area of motion of the shoulder joints. Active flexion (p = 0.000; r = -0.669), active
extension (p = 0.004; r = -0.520), active abduction (p = 0.000; r = -0.663), active adduction (p = 0.022; r = -0.423 ), passive
flexion (p = 0.001; r = -0.589), passive extension (p = 0.002; r = -0.543), passive abduction (p = 0.000; r = -0.676), passive
adduction (p = 0.038; r = -0.388). Conclusion: There is a significant correlation between limited joint motion and
functional ability in frozen shoulder patients at the Medical Rehabilitation Installation of Dr. Mohammad Hoesin
Palembang.
