After axillary nerve injury, the nature of the injury, the location of the injury, the extent of the injury and whether to carry out some early and effective intervention treatment will affect its recovery. The prerequisite for axillary nerve injury exercise is nerve recovery, so early surgical investigation is needed to determine the degree of nerve injury and early treatment with some neurotrophic drugs to promote nerve growth. The axillary nerve is mainly innervated by the deltoid muscle, which may innervate the anterior, middle or posterior part of the deltoid muscle depending on the injury site. The exercise of deltoid muscle is based on the size of its muscle strength, and different training methods are used: 1, 0 level of muscle strength is mainly based on low frequency electrical stimulation; 2, 1-2 level of muscle strength is mainly based on passive exercise training; 3, 3 level is mainly based on power-assisted exercise training; 4, about 4 level can be active training, including resistance training. Shoulder abduction movements are the main motor training method for deltoid or axillary nerve injuries.
