简要总结
This is a single-center prospective experimental pilot study to assess the feasibility, tolerability and effect of a 10-week gait training program combined with simultaneous blood flow restriction (BFR) on the walking speed of children, aged 8 to 18, with bilateral spastic cerebral palsy.
The children will receive a 10-week intervention (1 week of habituation without BFR + 9 weeks with BFR) comprising 3 30-minute treadmill sessions per week. At each session, the first 5 minutes will enable a gradual increase in speed, and then the maximum tolerated walking speed will be sought. Maximum speed corresponds to the walking speed maintained by the child for an effort of between 5 and 7 on Borg's 10-point VAS. The rehabilitator will encourage the child to maintain this speed and provide feedback on performance. The BFR setting will maintain an occlusion, at the root level of both lower limbs, of 60% of the total occlusal pressure.
Children receiving the 10-week EMBRIN program are expected to improve their walking ability and muscular strength, two targets recognized as priorities for individuals with CP by the HAS. In this population, a major limitation of implementing rehabilitation programs is the large amount of practice required to bring about significant changes. This large amount of practice requires a major investment on the part of the individual, as well as significant rehabilitation resources. Muscle-strengthening programs are also particularly repetitive and therefore not very motivating for children. The EMBRIN program could reduce the training load and duration required to impact functional performance in children with CP. It could also help reduce the cost of rehabilitation interventions and reduce physical therapy time for individuals with CP in favor of their social participation.
详细描述
Context :
Cerebral palsy (CP) is the leading cause of motor disability in children, with a prevalence of 1.77 cases per 1000 births. It is defined as a set of permanent developmental disorders of movement and posture, resulting from a non-progressive brain lesion affecting a developing brain. 60% of individuals with CP have a bilateral form. In this group, 98% of diplegics and 24% of quadriplegics will be "walkers", but more often than not with poor walking efficiency. In fact, these children show not only a reduction in walking speed, but also markedly reduced endurance. What's more, these children have reduced levels of physical activity, resulting in less participation in physical activities throughout their lives. Associated with these changes in motor activity, CP leads to morphological and architectural changes in the muscles, including reduced muscle volume, shorter muscle fascicles and increased intramuscular fat. These "bad" adaptations contribute to a reduction in muscle strength and power, leading to a progressive decline in functional capacity in adolescence and adulthood, associated with a sedentary lifestyle. In individuals with CP, gait training and muscle strengthening programs, carried out separately, have shown, respectively, a relative efficacy in improving walking activity and lower limb muscle strength. Rare programs combining these two interventions have been shown to be of interest in mildly affected children. In the geriatric population (without CP), where strengthening with heavy loads may be contraindicated and difficult to implement, Blood Flow Restriction (BFR) training has attracted considerable interest due to its simplicity of use and effectiveness. Indeed, the application of an inflatable cuff to the proximal part of a limb restricting blood flow, combined with low-load muscle strengthening, has shown similar effects to high-load strengthening on muscle function. BFR was also combined with functional training, and this combination showed superiority over functional training alone in improving functional activity. BFR does not appear to cause side-effects in typical adolescents, and has never been studied in children with CP.
Objectives and evaluation criteria :
Primary objective: to study the effect of a 10-week gait training program combined with simultaneous blood flow restriction (BFR), using a commercially available device, on the walking speed of children aged 8 to 18 with bilateral spastic cerebral palsy. To this end, a comparison of patients' walking speed will be carried out between the period D-70 to D0 (standard rehabilitation) and the period D0 to D+70 (walking training program + BFR). Walking speed will be assessed by the 10-meter walk test. The evaluation criterion is the change in walking speed between D-70-J0 and D0-J+70.

At each session, the first 5 minutes will enable a gradual increase in speed, and then the maximum tolerated walking speed will be sought. Maximum speed corresponds to the walking speed maintained by the child for an effort of between 5 and 7 on Borg's 10-point VAS. The rehabilitator will encourage the child to maintain this speed and provide feedback on performance. The BFR setting will maintain an occlusion, at the root level of both lower limbs, of 60% of the total occlusal pressure.
