Patient XXX, female, 33 years old, was admitted to the hospital with the main cause of “bilateral lower extremity motor, sensory and bowel dysfunction for more than 7 months due to a fall”. Main diagnosis: spinal cord injury (incomplete) after L1 vertebral fracture. Major impairment: 1. AIS: grade D, motor incomplete spinal cord injury 2. motor plane R/L: L1/ L1, motor score 45 on the left side, 31 on the right side 3. decreased muscle strength of both lower limbs, with the right side being the focus: hip flexors R/L: 2/3; knee extensors R/L: 1/4; knee flexors R/L: 1/3; ankle dorsiflexors R/L: 1/5; thumb extensors R/L: 1/4; ankle plantar flexors 4.Standing balance level 0, right knee and ankle joint control is not possible. 5. Barthel index score 55, daily life needs assistance Key problems to be solved: 1.Squat training on inclined bed: instruct the patient to squat on the inclined bed from a small angle, the angle is appropriate for the patient to complete 5 squats of both lower limbs independently. Expand the scope of application of inclined bed and create conditions for closed chain movement under weight loss. 2. Suspension exercise training: use neuromuscular activation technique to improve right knee control. Discharge status: AIS: Grade D, motor plane R/L: L1/ L1, motor score 47 on the left side and 36 on the right side. The right lower limb straight leg raise could be done independently without knee extension delay; independent outdoor walking with one hand crutches, poor pelvic control. Hip flexor R/L: 4/4; knee extensor R/L: 3/5; ankle dorsiflexor R/L: 1/5; thumb extensor R/L: 1/4; ankle plantar flexor R/L: 2/4Barthel index score of 70, basic self-care of daily life.
