Abstract

A shoe comprising a pressure sensor connected to a feedback system, e.g. providing a pressure threshold-related visual, auditory or sensory signal to a patient who is limited to partial weight bearing following injury or surgery. The sensor may comprise a removable electronic or mechanical pressure transducer under the heel and optionally the front part of the foot. The pressure limit may be varied by means of a dial and may be set to a percentage (e.g. 50%, 75%) of the patientâ s weight. The feedback may comprise an alarm; colour-coded lights; vibrations in the sole of the shoe or transmitted to a wrist or leg band; or words or sounds emitted via speakers in the shoe or transmitted (e.g. wirelessly) to an ear-piece or bracelet. The shoe may include ties and may be adjusted to a range of sizes.

Description

Partial weight bearing shoe
Statement of Invention
The idea to design a system of biofeedback to patients who need to walk partial weight bearing after sustaining injuries to the lower limbs, and also as part of rehabilitation process after surgery like joint replacement.
Advantage: Providing a clear measurement to what the patient can do,will improve the patient confidence in achieving progression and aid develop a clear language for health care worker to communicate the medical order in regard to the weight bearing status of patients.
Description:
Shoe that has pressure or force measurement circuit connected to an alarm feedback, pressure transducer can be calibrated to certain percentage of the body weight that can be put on it, and when the set measurement is exceeded an alarm would be set.
In more details: The shoe: An adjustable shoe e.g. with ties, contain pressure(force) measurement mechanism (can be mechanical or electronic) transducer at the heel part (and possibly the front part of the foot (forefoot). which is connected to an accessible dials that set the limit of the force that can be exerted through.
The shoe can be designed in way that is adjustable to a range of sizes.
The heel part that contains the pressure transducer, this piece is transferrable, so after calibrating it on the sound leg, it can be transferred to the special shoe to be connected to the electronic circuit.
Force measurement circuit is connected to a visual or audio or sensory feedback output, a light in the front of the shoe, or a sound spoken through some speakers in the shoe, or transmitted to an earpiece or a bracelet.
Another Version.
Two pressure transducers to be fitted under the heel part and the front part of the foot below the forefoot, let's say a 75% weight bearing status is required, the two pressure inputs will fire alarm separately in case the limit has been exceeded. So if patient exceeded the 75% in early phase of the stance when the heel part first on the floor, the feedback will be sent, in few seconds if it is exceeded while in full stance phase, the other transducer will fire the alarm.
The pressure measurement mechanism A small scale (example: electronic scale) with adjustable upper limit, a form of weight measurement device that can be calibrated to maximum limit.
The Calibration: Make the patient stand on the sound leg alone, wearing the same shoe design with the pressure transducer ( act like a scale) inserted through comparable site ( practically making the patient wear the other opposite special shoe) ; the force measurement device to set ( record) the 100% limit.
The pressure transducer in the shoe can be set to 75% or 50% ....etc. of this value, so when the patient starts putting weight on the affected leg in which the special shoe is wore, it will give a feedback to the patient in case the patient exceeded the limit.
Feedback mechanism: Can be 1-Visual (lights in the shoe itself): ex.: green if patient walking within the limits, Red if it is exceeded.
2-Sensory: by sending some vibration to patient skin according to the weight bearing limits, this can be achieved directly through the sole of the shoe from inside, or by transmitting signal to a wrist bracelet or leg band. Teaching the patient that a short vibration is (ok) longer transmission mean (it is above limits) 3-Audio by putting certain sound or words 4-An earphone that transmit wirelessly a sound feedback directly to the patient ear.

Claims (1)
