Definitions
- the invention relates to apparatus for dorsiflexion of a user's foot and a method therefor.
- Foot dorsiflexion supports venous blood flow return in a subject's lower limbs and is particularly useful for prevention of venous thrombosis.
- Apparatus for effecting foot dorsiflexion has been proposed for able bodied subjects in US Patent
- apparatus for dorsiflexion of a seated user's foot comprising a rigid base with heel restraining means and foot restraining means for restraining the user's foot on said base; forefoot elevation means underlying the foot's front portion alternately disposable between a first state whereby the foot's front portion lies adjacent to said base and a second state whereby the foot's front portion is elevated relative to said base thereby effecting its dorsiflexion.
- the apparatus of the present invention is particularly suitable for use as an accessory to wheelchairs, the apparatus being provided as a stand alone unit thereby facilitating dorsiflexion of a wheelchair bound user's feet in a convenient and comfortable manner whilst not impairing his mobility to perform everyday activities.
- a method for dorsiflexion of a seated user's foot comprising the steps of:
- Fig. 1 is a pictorial view of apparatus for dorsiflexion in a seated user's foot in accordance with the present inevntion;
- Fig. 2 is a perspective view of the inflatable member of the apparatus of Figure 1;
- Figs. 3A and 3B are side views of the apparatus of Figure 1 during operation; and
- Fig. 4 is a pictorial view of a wheelchair fitted with the apparatus of Figure 1.
- apparatus 1 for dorsiflexion of a seated user's foot includes a rigid platform 2 with a heel support 3 and a foot strap 4, and an inflatable member 6.
- the inflatable member 6 is connected to a compressor 7 under the control of a controller 8 controlling the inflatable member's maximum degree of inflation and its cyclic rate of inflation and deflation.
- the inflatable member 6 assumes a generally flat configuration (dashed lines) when deflated and a generally wedge-shaped configuration (solid lines) having its leading edge 6A directed toward the heel support 3 when inflated, the latter configuration adapted for raising the front portion of a user's foot relative to the platform 2 for its dorsiflexion.
- the inflatable member 6 includes a three sectioned cover 9 having sections 9A, 9B and 9C, the sections 9A and 9B being formed as a pouch 11.
- the pouch 11 contains a generally square single inflatable cell 12 divided into two equal sized compartments 12A and 12B by two seams 13A and 13B lateral of a central portion 14 enabling flow communication between the two compartments 12A and 12B.
- Each compartment 12A and 12B has a rigid member 16 disposed therein and one of the compartments 12A and 12B is provided with an inlet port 18 which also serves to inflate the other compartment.
- the cover 9 is formed into a closed generally equilateral shape whereby the section 9B is adjacent the platform 2 whereby the section 9C acts as a restraining member for limiting the maximum height of the inflatable member 6 when fully inflated.
- the inflatable member 6 requires a relatively small volume of compressed air to assume its wedge-shaped configuration thereby facilitating a relatively rapid cyclic rate of inflation and deflation.
- a user's foot is placed on the platform 2 and strapped in using the foot strap 4.
- the user sets the controller 8 to his preferred settings for maximum inflation height of the inflatable member 6 and cyclic rate of inflation and deflation.
- the maximum inflation height is about 7 cm from the platform 2 whereby the user's foot subtends an angle of about 20 degrees relative thereto.
- the cyclic rate of inflation and deflation can be set between 1 to 3 cycles per minute.
- the inflatable member is cyclically inflated and deflated by intermittent operation of the compressor 7, deflation being assisted by the natural downward tendency of a person's foot.
- a wheelchair 19 having left and right foot supports 21 A and 21B is provided with a system 22 for effecting dorsiflexion of wheelchair bound user's both feet, the system 22 including a rechargeable battery operated compressor 23, a controller 24 and two apparatus 26A and 26B for his left and right feet, respectively.
- the compressor 23 and the controller 24 are carried on a rack 27 and the apparatus 26A and 26B are respectively mounted on the wheelchair's foot supports 21 A and 2 IB whereby the system 22 is fully portable and therefore does not preclude the user from continuing with his everyday activities.
- the forefoot elevation member can be implemented by other mechanical or hydraulic devices, for example, a motorized eccentrically mounted wheel, and the like.
- the apparatus is primarily designed for use by users wearing shoes whereupon the inflatable member can be disposed underneath a user's metatarsals and/or toes. Alternatively, the apparatus can be used by barefooted users whereby the inflatable member is disposed underneath a user's metatarsals.
