The efficacy of upper extremity inhibitive casting: a single-subject pilot study

Area of Science:

• Neurology
• Pediatric Rehabilitation
• Orthopedic Technology

Background:

• Upper motor neuron damage can cause significant spasticity and functional limitations.
• Cerebral palsy is a common condition affecting motor function in children.
• Current treatments for spasticity include medication, physical therapy, and surgical interventions.

Purpose of the Study:

• To investigate the efficacy of short-term (48-hour) upper extremity inhibitive casting in managing spasticity.
• To assess the impact of inhibitive casting on active movement quality and hand use in a pediatric patient.
• To evaluate changes in spasticity and passive range of motion using objective clinical measures.

Main Methods:

• A single-case pilot study involving an 8-year-old girl with left upper extremity spasticity.
• Application of a 48-hour inhibitive cast with an integrated thermoplastic splint.
• Assessment of active movement quality via videotape analysis.
• Measurement of spasticity using the Modified Ashworth Scale.
• Quantification of elbow flexion/extension torque resistance using the Biodex System.

Main Results:

• Subjective improvements in active movement quality and increased hand awareness/use were reported post-casting.
• A trend towards decreased spasticity was observed with the Modified Ashworth Scale.
• A statistically significant reduction in passive movement resistance was recorded by the Biodex System.
• The observed symptom reduction was transient, with effects lasting under 3 days.

Conclusions:

• Short-term inhibitive casting shows potential as an adjunctive treatment for pediatric cerebral palsy with upper extremity spasticity.
• Further research with larger sample sizes and longer follow-up periods is warranted to confirm efficacy.
• The temporary nature of the benefits highlights the need for optimized casting protocols or combination therapies.
