A study testing Absorptiometry and indirect calorimetry and Questionnaires in people with Cerebral Palsy and Scoliosis, run by University Hospital, Montpellier at 1 site in France.
Trial summary
Cerebral palsy is the primary cause of disability in France. It is a non-progressive condition leading to movement and posture troubles, but also to cognitive and sensory problems. Spasticity is one of the most regular consequences. It leads to a muscular failure with permanent contractions. Read more about this study

About this study
Cerebral palsy is the primary cause of disability in France. It is a non-progressive condition leading to movement and posture troubles, but also to cognitive and sensory problems. Spasticity is one of the most regular consequences. It leads to a muscular failure with permanent contractions. Muscular dysfunction can generate scoliosis (in 60% of cases). Scoliosis can lead to pain, sitting difficulties (with chances of bedsores), and cardiopulmonary complications.
These children often have cachexia (eating difficulties, trouble with deglutition). It leads to a weakening of their immune defenses, which favors post-operative infections, a weakening of their respiratory muscles, and circulatory difficulties with negative effects on scarring. Cachexia is a pessimistic prognosis.

A back brace can be used to contain the scoliosis but never cures it. Another option for treating this affection would be surgery. Surgery is another treatment. It consists in straightening and holding the spine with metal rods, held by vertebral anchors placed at both ends of the scoliosis. Surgery is the gold standard.
Surgery induces risks such as bleeding, healing complications and infection. The probability to face complications increases with malnutrition.
The first hypothesis is that surgery could improve the nutrients intakes and the weight of the patient.
The investigators also believe that it could improve the patient's body composition (body fat and lean mass) and their basic metabolic rate.
The third hypothesis is that surgery-involved changes (nutrition enhancement, sitting improvement, decrease of respiratory work) could lead to an improvement of the patient's quality and life and respiratory functions.
The SORONOUS project aim to prove the benefits of this surgery from a nutritional and from a general point of view in order to help make the surgical decision and avoid any care delay. In addition, it aim to identify and quantify the post-operative weight gain; while providing us with a better understanding of the behavior of pre-operative cachexia among these patients.

What is being measured
The primary outcome is the main question the study is designed to answer.
Dietary intakes modifications before and after scoliosis surgery
Assessment of the dietary intakes in kcal/day (dietary intakes per os and/or gastrostomy and/or nasogastric tube) by nutrition questionnaires and based on the average food intake over the last 7 days. Caregivers will provide information on food intake for each day and each meal during the seven days preceding the consultation using a food intake sheet. A standardized table will be used to calculate the equivalents between food intake and energy intake (kcal). An average will be calculated over the 7 days to obtain a dietary intake in kcal/day. Comparison of the dietary intakes between one month before scoliosis surgery and six months after surgery
Measured: Between 1 month before surgery and 6 months after surgery
Secondary outcomes (17)

Comparison of the body composition one month before surgery and six months after surgery
Measured: Between one month before surgery and six months after surgery
Assessment of the achievement of customized goals established one month before the scoliosis surgery

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Cerebral palsy is the primary cause of disability in France. It is a non-progressive condition leading to movement and posture troubles, but also to cognitive and sensory problems. Spasticity is one of the most regular consequences. It leads to a muscular failure with permanent contractions. Muscular dysfunction can generate scoliosis (in 60% of cases). Scoliosis can lead to pain, sitting difficulties (with chances of bedsores), and cardiopulmonary complications.
These children often have cachexia (eating difficulties, trouble with deglutition). It leads to a weakening of their immune defenses, which favors post-operative infections, a weakening of their respiratory muscles, and circulatory difficulties with negative effects on scarring. Cachexia is a pessimistic prognosis.
A back brace can be used to contain the scoliosis but never cures it. Another option for treating this affection would be surgery. Surgery is another treatment. It consists in straightening and holding the spine with metal rods, held by vertebral anchors placed at both ends of the scoliosis. Surgery is the gold standard.
Surgery induces risks such as bleeding, healing complications and infection. The probability to face complications increases with malnutrition.
The first hypothesis is that surgery could improve the nutrients intakes and the weight of the patient.

The SORONOUS project aim to prove the benefits of this surgery from a nutritional and from a general point of view in order to help make the surgical decision and avoid any care delay. In addition, it aim to identify and quantify the post-operative weight gain; while providing us with a better understanding of the behavior of pre-operative cachexia among these patients.

Where is the study taking place?
The record lists 1 site in France. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
