Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

PURPOSE: The study aims to compare study between Botulinum toxin-A injection and shock waves therapy on hypertrophic scars in hand-burned children.

BACKGROUND: Burn injuries can cause significant physical and psychological distress, especially when they result in hypertrophic scarring. In children, who are particularly vulnerable to these injuries, it is important to accurately assess the severity of these scars and their impact on functionality.

HYPOTHESES: There is no significant difference between the combined effect of the traditional physical therapy program with botulinum toxin-A injection and the traditional physical therapy program with shock waves therapy on improving wrist extension, ulnar deviation, radial deviation, hand grip strength, and severity of the scar on hypertrophic scars in hand-burned children.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Control group

The control group will receive the physical therapy program and conduct five times per week over four consecutive weeks under the supervision of a physical rehabilitation specialist.

Group Type ACTIVE_COMPARATOR

physical therapy treatment

Intervention Type OTHER

The control group will receive the physical therapy program and conduct five times per week over four consecutive weeks under the supervision of a physical rehabilitation specialist. The primary focus of the program was to improve scar malleability, lengthen muscles and tendons, enhance joint mobility, and to restore functionality. Each session lasted almost for 45 minutes and consisted of therapeutic paraffin application; deep tissue massaging (5 minutes); stretching exercises; active ROM exercises.

Study group A

The study group A will receive Botulinum toxin-A injection in addition to physical therapy program as control group

Group Type ACTIVE_COMPARATOR

Botulinum toxin-A injection in addition to physical therapy program

Intervention Type OTHER

Two injection procedures will be used. The first is an EMG-guided BTX-A administration (Botox®, Allergan PLC, Dublin, Ireland) that will be localized to the motor endplate zone of the wrist flexors, radial and ulnar deviators. The second is a meso-injection procedure, where the BTX-A will be injected subdermal, intradermal, and into the scar (around the periphery and into the center).

Study group B

The study group B will receive shock wave therapy in addition to physical therapy program as control group.

Group Type ACTIVE_COMPARATOR

shock wave therapy in addition to physical therapy program

Intervention Type OTHER

After wound and skin graft healing (\~ 90 days post-surgery), the unfocused shockwave will be applied to the site of burn injury on the volar aspect of the hand of the subjects and will allocate to the shock wave therapy intervention arm. The treatment will be delivered using a portable shockwave device (Zimmer enPuls, EMS physio Ltd, Germany).
