Passive motion therapy for infants with arthrogryposis

Area of Science:

• Pediatric Orthopedics
• Rehabilitation Medicine
• Developmental Pediatrics

Background:

• Arthrogryposis multiplex congenita (AMC) presents significant challenges due to contractures affecting multiple extremities.
• A substantial portion of AMC patients (40%) also exhibit multiple congenital anomalies, complicating treatment.
• Previous treatment approaches for AMC have varied, necessitating a structured, evidence-based program.

Purpose of the Study:

• To present a comprehensive treatment program for arthrogryposis multiplex congenita.
• To evaluate the efficacy of early passive stretching and serial splinting in improving joint motion and function in infants and young children with AMC.
• To define the role of surgical intervention within a multidisciplinary AMC treatment regimen.

Main Methods:

• Development of a treatment program based on clinical experience with 95 pediatric patients diagnosed with AMC.
• Implementation of daily intensive passive stretching exercises for affected joints.
• Application of serial splinting techniques to progressively correct joint contractures.
• Selective use of surgical procedures for residual deformities unresponsive to conservative management.

Main Results:

• The developed program, emphasizing early passive stretching and serial splinting, demonstrated substantial improvements in patient function.
• Ninety percent of patients presented with contractures in all extremities, highlighting the severity and widespread nature of the condition.
• Conservative management (stretching and splinting) was effective in increasing joint mobility and functional capacity for the majority of the study cohort.

Conclusions:

• A comprehensive, conservative program focused on early passive stretching and serial splinting is highly effective for managing arthrogryposis multiplex congenita.
• This regimen significantly enhances joint motion and functional outcomes in infants and young children with AMC.
• Surgical intervention should be reserved for cases with persistent deformities that do not respond adequately to intensive non-operative treatment.
