Summary

Delayed sensory rehabilitation significantly improved two-point discrimination in toe-to-hand transfers. This sensory reeducation program, even when started years after surgery, enhanced tactile sensation for patients.

Area of Science:

  • Reconstructive Surgery
  • Neurorehabilitation
  • Sensory Physiology

Background:

  • Toe-to-hand transfer is a reconstructive surgical technique to restore hand function.
  • Sensory feedback is crucial for the functional success of replanted or transferred digits.
  • Optimal timing for sensory rehabilitation after digit reconstruction remains an area of investigation.

Purpose of the Study:

  • To evaluate the efficacy of a delayed sensory rehabilitation program in patients who underwent toe-to-hand transfers.
  • To determine if sensory reeducation initiated long after the surgical procedure can yield significant improvements in tactile sensibility.

Main Methods:

  • A cohort of 13 patients with 22 toe-to-hand transfers participated in the study.
  • Sensory reeducation commenced at a mean of 38 months post-transfer, utilizing a home-based Disk-Criminator (TM) program.

  • Therapist monitoring occurred monthly for a mean of 3.3 months, followed by final sensory evaluations.

    • Main Results:

    • A statistically significant improvement in two-point discrimination was observed across all 22 toe transfers.
    • Average improvement was 7 mm for static two-point discrimination and 6 mm for moving two-point discrimination.
    • The observed enhancements were highly significant (P < 0.0001).

    Conclusions:

    • Delayed sensory rehabilitation is effective in improving tactile sensibility after toe-to-hand transfers.
    • Even years after surgery, structured sensory reeducation can lead to measurable functional gains.
    • These findings support the implementation of sensory reeducation protocols regardless of the time elapsed since digit reconstruction.
