Distributed practice, with one session daily, significantly improved microsurgical vascular anastomosis skills in neurosurgeons compared to massed practice. This learning protocol enhances fine motor skill acquisition for complex procedures.

Area of Science:

  • Neurosurgery
  • Microsurgery
  • Surgical Skills Training

Background:

  • Microsurgical vascular anastomosis (MVA) is a complex skill requiring extensive practice.
  • Optimal practice protocols for mastering MVA are not well-established.
  • This study investigates distributed versus massed practice for MVA learning.

Purpose of the Study:

  • To compare the efficacy of distributed and massed practice protocols for learning microsurgical vascular anastomosis.
  • To analyze the impact of different practice frequencies on fine motor skill acquisition in neurosurgery.

Main Methods:

  • Ten neurosurgeons with prior microsurgery experience but no MVA experience were randomized.
  • Participants practiced MVA using either a distributed (1 session/day) or massed (6 sessions/day) protocol over 24 sessions.

  • Performance was assessed via anastomosis scores, time per stitch, and total anastomosis time during practice and recall tests.

    • Main Results:

    • The distributed practice group demonstrated significantly higher anastomosis scores and shorter completion times in late practice trials and recall tests.
    • Massed practice exhibited a fatigue effect, negatively impacting performance towards the end of practice blocks.
    • Despite lower overall scores, massed practice showed a consistent improvement trend.

    Conclusions:

    • Distributed practice is more effective for learning microsurgical vascular anastomosis, likely due to the spacing effect.
    • Massed practice may be improved with modifications, such as increased practice blocks, for comparable outcomes.
    • Further research is needed to optimize massed practice protocols for surgical skill acquisition.
