Shoulder pain, range of motion, and functional motor skills after acute tetraplegia

Abstract

Salisbury SK, Choy NL, Nitz J. Shoulder pain, range of motion, and functional motor skills after acute tetraplegia. Arch Phys Med Rehabil 2003;84:1480–5. Objectives To investigate (1) the prevalence and course of shoulder pain in acute tetraplegia and (2) its relationship with range of motion (ROM) and function and any associated risk factors. Design A longitudinal prospective study. Setting Spinal injury unit in an Australian hospital. Participants Inpatients with acute tetraplegia. Interventions Not applicable. Main outcome measures Demographics, pain intensity, shoulder ROM, and functional motor skills. Results The prevalence of pain during rehabilitation was 85%. Risk factors associated with pain during rehabilitation included age less than 30 years or more than 50 years (F=8.892, P=.064), admission motor level at C2–5 (F=5.833, P=.016), admission sensory level at C2–5 (F=7.543, P=.006), lower left upper limb ( P=.005; 95% confidence interval [CI], −14.74 to −2.86) and total American Spinal Injury Association motor scores ( P=.009; 95% CI, −29.53 to −4.67), and a shorter duration of bedrest (F=5.794, P=.055). Subjects with pain lost ROM in left abduction ( P=.038; 95% CI, −25.9 to −0.9) and right abduction ( P=.05; 95% CI, −30 to 9.3). No relationship existed between shoulder pain and functional motor skills on discharge. Conclusion Shoulder pain is common in acute tetraplegia and is associated with loss of shoulder ROM. Risk factors identified include age, injury level, and duration of bedrest. Areas for further study are identified.
