Motor Imagery Prior to or Alongside Initial Prosthetic Gait Training in Acute Transtibial Amputees: A Feasibility Pilot Study
In Brief
A clinical study evaluating Motor Imagery for Transtibial Amputation - Unilateral and 2 related conditions. Completed, enrolled 10 participants across 1 site.
Signals
Detailed Summary
This study included the development of motor imagery (i.e., the cognitive process of mentally reheasing a motor task) protocol for improving prosthetic gait among acute transtibial amputees. Further, the researchers investigated whether praciticng motor imagery before or alongside initial temporary prosthetic training (aka VESSA) would affect measures of functional status, pain, prosthethis embodiement and motor imagery ability.

Participants attended the motor imagery training alongside actual temporary prosthetic (VESSA) training
Interventions
The motor imagery intervention aimed to: (1) introduce rationale, mechanisms of action, and advantages of MI; (2) facilitate kinesthetic and functional familiarization with the prosthesis; and (3) enhance prosthetic gait, weight-bearing, balance and turning. The protocol followed MI paradigms and methodologies (e.g., combining visual and kinesthetic modalities), including the PETTLEP model that was previously used in amputees. The MI contents addressed movement range of motion, quality, timing, and lower extremity and whole-body intersegmental coordination with motor tasks serving as outcome measures not being explicitly practiced. The following components were included: 1. Introduction to MI- definition, mechanisms of effect, advantages, modalities, and perspectives. 2. Acquaintance with and embodiment of the stump, MI of the prosthesis and MI of the stump-prosthesis interaction (e.g., contact area, pressure). 3. Weight bearing and shifting during sit-to-stand, standing and gait.
