Foot, ankle and lower leg exerciser |
摘要 |
The exerciser described herein for strengthening or rehabilitating the feet, ankles and lower legs of the user comprises two foot pedals supported on a vertical bar screwed into the support for the pedals and having a ball joint at the bottom thereof which fits into a cavity in the base support and thereby permits a swivelling action. Between the pedals and the base support there is also a supporting spring for which the compression can be increased or decreased by turning the threaded part of the bar one way or the other way in a threaded opening in the underside of the pedal supporter.
