Kinetics of Lower Limb Prosthesis: Automated Detection of Vertical Loading Rate

An autologus lower limb prosthesis.

Van Nes rotationplasty is a reconstructive and salvage procedure of the lower limb. The technique replaces the amputated thigh and knee with an autologus biological 'prosthesis', the patient's own ipsilateral ankle, which is rotated 180 degrees and fixed at the level of the contralateral knee. This procedure was first adapted by Borggreve of Germany in 1930 to treat a knee joint destroyed by tu...

Estimating Lower Limb Skeletal Loading

Assessment of Lower Limb Prosthesis through Wearable Sensors and Thermography

This study aimed to explore the application of infrared thermography in combination with ambulatory wearable monitoring of temperature and relative humidity, to assess the residual limb-to-liner interface in lower-limb prosthesis users. Five male traumatic transtibial amputees were involved, who reported no problems or discomfort while wearing the prosthesis. A thermal imaging camera was used t...

Pseudo-Kaposi's sarcoma because of suction-socket lower limb prosthesis.

Pseudo-Kaposi sarcoma is a benign reactive vascular proliferation mainly involving the lower legs, which can be related to acquired chronic venous insufficiency or congenital arteriovenous malformations. In its most common presentation, acroangiodermatitis is seen in patients with chronic venous insufficiency of the lower limbs as an exaggeration of the stasis dermatitis. However, rare reports ...

Investigation of lower-limb tissue perfusion during loading.

An extant tissue indentor used for amputee residual limb tissue indentation studies was modified to include laser Doppler flowmetry (LDF) to enable measurement of tissue perfusion during indentation. This device allows quantitative assessment of the mechanical and physiological response of soft tissues to load, as demonstrated by indentation studies of the lower-limb tissues of young healthy su...
