ObjectiveTo design a simple leg-sliding rehabilitation equipment for patients with lower limb dysfunction who need to exercise their leg muscles in bed at the early stage of rehabilitation. MethodsThe mechanism scheme was designed using the crank slider transmission system. The kinematic model was established and the structural dimensions were determined according to the human joint mobility, analysis and verification were then implemented; and the strutural strength of the machanism was verified, and based on the analysis, a protype was built to verify the feasibility of proposed scheme. ResultsThe range of joint activities of the proposed mechanism was in line with the normal human joint activities, the structural strength met the requirements, the prototype operated smoothly, and the actual running speed was basically consistent with the theoretical planning speed. ConclusionThis design could meet the needs of rehabilitation training for bedridden patients with lower limb dysfunction at the early stage of rehabilitation. It has the advantages of small size and light weight, which provides reference value for promoting the development of miniaturized and lightweight lower extremity rehabilitation equipment.

To summarize the clinical experience of Professor LIU Shangyi in treating pruritus vulvae. It is believed that women have the physiological characteristics of liver and kidney as the root， and their pubic area is easily attacked by wind-dampness pathogenic qi， so the core mechanism of pruritus vulvae is proposed as wind-dampness accumulation and deficiency of liver and kidney. The core treatment method is to dispel wind-dampness and nourish the liver and kidneys， and modify the Danggui Decoction （当归饮子） to form a self-prescribed Yinyang Formula （阴痒方） as the basic prescription to treat pruritus vulvaen.
