PURPOSE: This study compared traditional rehabilitation as a treatment modality after plaster cast treatment of Colles' fracture with a combination of individualized blood flow restriction (BFR) and traditional rehabilitation. METHODS: Twenty-eight participants were randomized into a BFR group and a non-BFR group after plaster cast treatment of Colles' fracture. The BFR group completed traditional rehabilitation with a medical grade tourniquet applied to the upper arm, and the non-BFR group underwent traditional rehabilitation only. Patients were followed up with radiographic outcomes (palmar tilt and radial inclination) to ensure the stability of the fracture. Clinical assessment of patient-rated wrist evaluation (PRWE) score, grip strength, pinch strength, wrist range of motion (ROM), and muscle stiffness was conducted at cast removal and 6 wk after cast removal. Two-way repeated-measures ANOVA determined significant interactions between time and group in the aforementioned variables. An independent-sample t-test assessed the differences in baseline variables and radiographic outcomes. RESULTS: Significant interactions between time and group were noted for PRWE score (F 11.796, p = 0.002, eta2p 0.339), grip strength (F 5.445, p = 0.029, eta2p 0.191), and wrist ROM (ulnar deviation; F 7.856, p = 0.010, eta2p 0.255). No significant interactions between time and group were found in measurements of pinch strength or wrist ROM (flexion, extension, radial deviation, pronation, supination). An independent-sample t -test showed no significant difference in baseline variables and radiographic outcomes between the groups before or after intervention. CONCLUSIONS: This study found that combining individualized BFR with traditional rehabilitation resulted in greater increases in PRWE score, grip strength, and wrist ROM (ulnar deviation) than traditional rehabilitation alone. Therefore, adding individualized BFR to traditional rehabilitation might be a better option for treatment for similar patients.
