Impact of Geko Neuromuscular Stimulator on Preoperative Preparation in Ankle Fractures

To explore the impact of the Geko neuromuscular stimulator on preoperative preparation in patients with ankle fractures.

Quasi-experiment study. Place and Duration of the Study: Department of Foot and Ankle Surgery and Department of Orthopaedics, Beijing Tongren Hospital, Capital Medical University, Beijing, China, between December 2020 and 2021.

This quasi-experiment study included patients with ankle fractures treated with Geko neuromuscular stimulator before surgical fixation. The primary outcome was limb swelling at 24, 48, and 72 hours (h) after admission, and the secondary outcomes were pain according to visual analogue scale (VAS) at 12, 24, and 48 hours after admission, preoperative waiting time, and comfort 4 and 72 h after admission.

A total of 60 patients were included in the study; 30 in the conventional treatment group (mean age 41.16 ± 2.01 years) and 30 in the Geko group (mean age 40.22 ± 2.68 years). The limb swelling in patients was significantly different between the Geko and conventional treatment groups (p = 0.004). Besides, the swelling values at 48 (p < 0.001) and 72 (p < 0.001) hours were significantly lower than those at 24 hours. The pain in patients was significantly different between the Geko and conventional treatment groups (p = 0.007). Besides, the swelling values at 24 (p < 0.001) and 48 (p < 0.001) hours are significantly lower than those at 24 hours. Comfort was significantly higher at 4 h (69.54 ± 2.18 vs. 67.22 ± 3.14, p = 0.002) and 72 h [(88.50 (84.00 - 94.00) vs. 82.14 ± 3.08, p < 0.001)] after admission. The preoperative waiting time (3.52 ± 1.8 vs. 5.15 ± 2.1 hours, p = 0.002) was significantly shorter in the Geko group.

The Geko neuromuscular stimulator is a useful option for preoperative preparation in patients with ankle fractures to reduce local swelling and pain and improve patients' comfort.
