Background and study aims
Cerebral palsy is a highly debilitating disorder that results from brain damage during development or birth. It can cause motor and language disabilities. Spasticity is one common complication of cerebral palsy which makes movement of upper and lower limbs difficult and often causes joint deformities. To manage spasticity, less intrusive recommendations include the use of hand orthotics. However, in resource-constrained areas, orthotics are often unaffordable and poorly constructed. 3D-printed orthotics could provide an innovative solution, as they utilize high precision manufacturing with low-cost materials. The aim of this study is to determine whether 3D printed orthotics are as effective as conventional orthotics at preventing hand deformities in children with cerebral palsy.
Who can participate?
Children under 12 years old with cerebral palsy
What does the study involve?
Participants are randomly allocated to use either 3D-scanned-and-printed hand orthoses or conventional orthoses hand-made by an orthopedist. The total length of orthotics use is 4 months. Participants receive the orthotics and maintenance service free of cost. In case of side effects, such as the developments of blisters, all treatment costs are covered by the researchers. After 4 months, improvements in hand range of movement are compared between users of 3D-printed orthoses and conventional orthoses.
What are the possible benefits and risks of participating?
Immediate benefits include monitoring of hand function for participants and guaranteed replacement of the orthoses if they break. Also, if the orthoses prove to be equivalent and effective, participants are given access to them after the study. The main risks include the development of skin blisters that can be prevented with proper use of the orthoses. Participants are provided with instructions and are monitored for side effects.
Where is the study run from?
Hospital de Rehabilitacion del Callao (Peru)

| Scientific title | An equivalence trial comparing 3D-printed hand orthotics and conventional orthoses in maintaining the range of wrist extension and the management of spasticity among children with cerebral palsy |
| Study objectives | The results of wrist extension ranges in the group treated with 3D-printed hand orthotics are better than the ranges in the group treated with conventional orthoses. |
| Ethics approval(s) | Institutional Ethics Committee for Humans of Cayetano Heredia University, 04/04/2017, ref: 182-21-16 |
| Health condition(s) or problem(s) studied | Children diagnosed with cerebral palsy |
| Intervention | One hundred children <12 years old diagnosed with cerebral palsy will be recruited from a local rehabilitation hospital over the course of 6 months and invited to participate in the study. The intervention consists of the use of hand orthoses, commonly known as splinting, for 4 months. The randomization process will be carried out through the online system www.randomization.com. The intervention group A will receive 3D-scanned-and-printed hand orthotics. The intervention group B will receive conventional orthoses hand-made by an orthopedist. In addition, both groups will receive reminder phone-calls of the proper use of the orthoses. Hand orthoses should be used permanently, even when sleeping, in one or both hands if necessary. Both groups will receive this information. The orthosis can only be removed during the activities of cleaning, dress and during the rehabilitation sessions. Participants will receive the orthotics and maintenance service free of cost. In case of adverse events, such as the developments of blisters, all treatment costs will be covered by the researchers. After 4 months, improvements in hand range of movement from baseline will be compared between users of 3D-printed orthoses and conventional orthoses. |

Eligibility
| Participant type(s) | Patient |
|---|---|
| Age group | Child |
| Upper age limit | 12 Years |
| Sex | Both |
| Target number of participants | The total number of participants to recruit will be 130 participants in total |
| Key inclusion criteria | This study will include children younger than 12 years with a diagnosis of spastic cerebral palsy who have a score of >1+ on the Ashworth scale. These criteria are applied because, at that age, children with cerebral palsy are at an age where there is a greater risk of suffering from deformities but also, they are preventable. Parents of children who meet the inclusion criteria should be able to understand the study objectives and not intend to move in the next 6 months. These criteria are applied as part of the information in the study will be obtained from the parents. If they are not able to understand the objectives of the study or plan to move, this will not allow adequate measurements or allow them to be attended in a timely manner in case of an emergency or adverse event. |
| Key exclusion criteria | This study will not include children who have undergone surgical intervention for the treatment of spasticity or who have indication for surgery to correct hand deformities. Neither will children who are currently receiving botulinum toxin for the treatment of spasticity or any other treatment for spasticity, including prior use of orthoses. The presence of allergic reactions to contact with orthotic material will also be considered as an exclusion criterion. These criteria are to be applied in order to ensure the orthoses effectiveness. If participants are already receiving some others treatments for spasticity, they will not require the use of orthoses. If during the study the participants require surgery or are prescribed the use of Botox, it will also be considered an exclusion criterion for the analysis of the study. |
