Claim 29:
30. A knee brace comprising:
a flexible sleeve that comprises a flexible fabric;
a memory device configured to store a reference configuration of the flexible sleeve, wherein the reference configuration represents a reference angle of bending of the flexible sleeve;
a first sensor configured to measure an angle of bending of the flexible sleeve;
a sleeve tightening mechanism comprising at least one motor and configured to adjust a tightness of the flexible sleeve; and
a controller configured to receive a first measurement signal from the first sensor representing, or indicative of, the angle of bending (θmeasure) of the flexible sleeve, compare the angle of bending of the flexible sleeve with the reference angle of bending (θref) of the flexible sleeve, and control the sleeve tightening mechanism to tighten the flexible sleeve, as compared to a normal state of the flexible sleeve, upon determining that the flexible sleeve is bent past the reference angle of bending by a first threshold angle (θthreshold1), θmeasure>θref+θthreshold1;
wherein the controller is configured to continue to control the sleeve tightening mechanism to tighten the flexible sleeve until the controller receives a second measurement signal from the first sensor and determine that the angle of bending (θmeasure) of the flexible sleeve beyond the reference angle (θref) is less than a second threshold angle (θthreshold2), then the controller is configured to control the sleeve tightening mechanism to reduce the tightening of the flexible sleeve, θmeasure<θref+θthreshold2.
