Task-specific fall prevention training is effective for warfighters with transtibial amputations.

Area of Science:

• Rehabilitation science
• Biomechanics
• Prosthetics and orthotics

Background:

• Falls and fear of falling limit functional capabilities in lower extremity amputees.
• Existing fall prevention programs have not been tested in amputee populations.
• Transtibial amputations present unique challenges to balance and mobility.

Purpose of the Study:

• To assess the effectiveness of a task-specific fall prevention training program in unilateral transtibial amputees.
• To quantify improvements in trunk control and responses to simulated trips.
• To evaluate the retention of training benefits and patient-reported outcomes at 3 and 6 months post-intervention.

Main Methods:

• A prospective cohort study involving 14 male military service members with unilateral transtibial amputations.
• A six-session, 2-week training program utilizing a microprocessor-controlled treadmill to deliver task-specific postural perturbations.
• Assessment of trunk kinematics (peak flexion angle and velocity) during virtual reality-simulated trips and patient-reported balance confidence questionnaires.

Main Results:

• Significant improvements in peak trunk flexion angle and velocity were observed post-training, indicating enhanced postural control.
• Training benefits, including improved trunk control, were maintained up to 6 months after the program completion.
• Subjects reported a reduction in stumbles, semicontrolled falls, and uncontrolled falls following the training intervention.

Conclusions:

• Task-specific fall prevention training is an effective rehabilitation strategy for reducing falls in individuals with transtibial amputations.
• The training program enhances trunk control and balance confidence, leading to improved functional mobility.
• This approach offers a promising method for improving safety and independence in amputee populations.
