A comparison of the efficacy of 5% glucose and saline solution in shoulder joint hydraulic distension for the treatment of frozen shoulder

For patients with painful frozen shoulder lasting over a month, both treatments resulted in substantial pain relief and improved function. The 5% glucose solution produced more pronounced benefits at 4 and 12 weeks, particularly with regard to pain relief and increased shoulder mobility. Key messages What is already known about this topic: Although extensive research has been conducted on frozen shoulder, the most effective treatment has yet to be identified. What does this study contribute: This is the first study to use a 5% glucose solution as the primary distending agent in shoulder joint hydraulic distension for frozen shoulder (FS), which is a novel approach not previously explored in the literature. How might this study affect research, practice or policy: This study provides a new clinical protocol for the treatment of frozen shoulder.
