Suspension training: Slingexercisetraing, a strength training, functional muscle rehabilitation method. Suspension training highlights comprehensive motor-sensory training, emphasizing closed-chain exercises in an unstable state to achieve the best evoked effect on the sensory-motor organs and effectively improve the strength and stability of the core muscle groups. By strengthening the trunk muscles and non-dominant limbs, strengthening the feedback and integration between nerves and muscle groups to improve the body’s balance, control ability and stability in sports. Core muscle groups: the first group is the deep core muscle group, also known as the local stability muscle group, including transverse abdominis, multifidus, internal abdominal oblique and lumbar square muscle; the second group is the superficial core muscle group, also known as the overall stability muscle group, including rectus abdominis, internal abdominal oblique, external abdominal oblique, erector spinae, lumbar square muscle and hip muscle group. Core stability refers to the stable posture of the pelvis and trunk position during exercise, creating fulcrums for upper and lower extremity movements, and coordinating the force generation, transmission and control of the extremities to optimize. Stability is a prerequisite for movement and function. Advantages of S-E-T treatment 1. Active movement of the child can avoid the phenomenon of insufficient active movement of children with cerebral palsy 2. Deep stable muscle groups that are usually difficult to stimulate can be trained to avoid one-sided muscle strength training and prevent muscle strength imbalance 3. Coordinated muscle contraction can be improved (the rich closed-chain movement of S-E-T can activate active, synergistic and antagonistic muscles at the same time and make the three coordinate with each other to produce contraction). 4.It can stimulate the sensory-motor organs and improve the coordination of sensation and movement 5.Improve the core area function of children with cerebral palsy (the core area refers to the middle of the chest to the middle of the thigh), improve the control of the pelvis and trunk, and correct the spinal deformity
