Abstract
Abstract A patient's lower leg and foot are received by a "boot" which is movable to guide and control the performance of various exercising functions. The sole of the boot is pivoted relative to the leg-receiving portions for soleus pumping exercises, and the entire boot is supported for vertical and horizontal pivoting movement on a longitudinally guided carriage which permits both longitudinal and transverse horizontal boot movement for knee bending and hip exercises.

90 words
Therapeutic exercising apparatus comprising, elongated guide means, a carriage assembly engaged with and guided by said elongated guide means, a boot assembly supported on said carriage assembly, said boot assembly including a leg receiving member for engaging the lower leg of a patient and a sole member for engaging the sole of a patient's foot, said sole member being movable relative to said leg receiving member about a substantially horizontal pivot axis, said boot assembly being movable in a substantially horizontal linear path and in a substantially horizontal arcuate path.
Claim 2
Dependent Claim
90 words
Therapeutic exercising apparatus comprising, elongated guide means, a carriage assembly engaged with and guided by said elongated guide means, a boot assembly supported on said carriage assembly, said boot assembly including a leg receiving member for engaging the lower leg of a patient and a sole member for engaging the sole of a patient's foot, said sole member being movable relative to said leg receiving member about a substantially horizontal pivot axis, said boot assembly being movable in a substantially horizontal linear path and in a substantially horizontal arcuate path.
Claim 3
Dependent Claim
21 words
The apparatus of claim 1 including pivot means which enables the boot assembly to swing horizontally about a substantially vertical axis.
Claim 4
Dependent Claim
49 words
The apparatus of claim 2 wherein the boot assembly is movable from a first position where it is oriented longitudinally of the guide means for knee flexion and extension exercises, to a second position where it is oriented transversely of the guide means for hip abduction and adduction exercises.
Claim 5
Dependent Claim
34 words
The apparatus of claim 2 wherein said boot assembly is connected to said carriage assembly for movement about a horizontal pivot axis to permit knee flexion and extension exercises during movement of the carriage.
Claim 6
Dependent Claim
25 words
The apparatus of claim 4 including lock means for preventing said boot assembly from moving relative to said carriage assembly about said horizontal pivot axis.
Claim 7
Dependent Claim
49 words
The apparatus of claim 4 wherein the boot assembly is movable from a first position where it is oriented longitudinally of the guide means for knee flexion and extension exercises, to a second position where it is oriented transversely of the guide means for hip abduction and adduction exercises.
Claim 8
Dependent Claim
34 words
The apparatus of claim 1 wherein said boot assembly is connected to said carriage assembly for movement about a horizontal pivot axis to permit knee flexion and extension exercises during movement of the carriage.
Claim 9
Dependent Claim
