A model-based approach to stabilizing crutch supported paraplegic standing by artifical hip joint stiffness [PDF]

, 2003
The prerequisites for stable crutch supported standing were analyzed in this paper. For this purpose, a biomechanical model of crutch supported paraplegic stance was developed assuming the patient was standing with extended knees.

Vascularized pedicle iliac bone grafts as a hip-preserving surgery for femur head necrosis: a systematic review

Journal of Orthopaedic Surgery and Research, 2019
Background Osteonecrosis of the femoral head was gradually concerned as a global disease for its progression to collapse of the femoral head, ultimately causing the arthritic change. Due to the high incidence of this disease in young people, arthroplasty

Cycle-to-cycle control of swing phase of paraplegic gait induced by surface electrical stimulation [PDF]

, 1995
Parameterised swing phase of gait in paraplegics was obtained using surface electrical stimulation of the hip flexors, hamstrings and quadriceps; the hip flexors were stimulated to obtain a desired hip angle range, the hamstrings to provide foot ...
