Abstract
Introduction:
Postoperative exercise improves arteriovenous fistula maturation for hemodialysis. However, scarce evidence exists about hand grip device on fistula maturation process.
Objective:
To evaluate the efficacy of a hand grip training program on arteriovenous fistula maturation in population with Chronic Kidney Disease 5-5D.
Methodology:
Prospective study (15 months). Patients were randomized to handgrip (HG) or control group (CG) postoperatively. HG performed a training program using a hand grip device. CG received conventional care. Upper limb muscle strength (ULMS), Duplex ultrasonography, and clinical arteriovenous fistula maturation were assessed at 4 and 8 weeks postoperatively.
Results:
At 8 weeks after fistula creation, upper limb muscle strength was increased only in the handgrip group (from 18 ± 6 to 23 ± 9 kg, p = 0.023). Clinical maturation was significantly greater in handgrip group versus control group, both at 4 weeks after intervention (62% vs 23%, p = 0.004) and at 8 weeks (65% vs 27%, p = 0.004). Similarly, the Doppler ultrasonography maturation rates were significantly greater in the HG, both at 4 weeks (HG: 84% vs CG: 47%; p = 0.004) and at 8 weeks (HG: 89% vs CG: 50%; p = 0.002).
Conclusions:
The hand grip is a useful and safety training device to improve the arteriovenous fistula maturation. This device results a new therapeutic option for maturation in arteriovenous fistula, particularly in distal arteriovenous fistula. Further studies are required to support these results.
