Orthotic technique for dystonia musculorum deformans

Area of Science:

• Neurology
• Orthopedics
• Rehabilitation Medicine

Background:

• Traditional orthotic interventions, including tone-reducing, inhibitive casting, and standard ankle-foot orthoses, are established treatments for improving gait and reducing tone in patients with cerebral palsy and head injuries.
• Dystonia musculorum deformans presents unique challenges in managing severe foot deformities, such as inversion and supination, particularly during weight-bearing activities.

Observation:

• A patient diagnosed with dystonia musculorum deformans exhibited significant inversion and supination of the left foot during weight-bearing.
• This patient experienced suboptimal outcomes and issues with abrasions when fitted with conventional metal double-upright ankle-foot orthoses incorporating a lateral T-strap.

Findings:

• A novel tone-reducing ankle-foot orthosis (TRAFO) was implemented for the patient with dystonia musculorum deformans.
• The TRAFO demonstrated significant success in mitigating the patient's foot deformities, specifically reducing inversion and supination during weight-bearing.

Implications:

• The successful application of the TRAFO suggests its potential as an effective treatment for severe foot deformities in dystonia musculorum deformans.
• This case highlights the TRAFO's ability to improve patient mobility by allowing unaided walking and minimizing skin complications, offering a promising alternative to conventional orthoses.
