Abstract

A night splint for a user'"'"'s foot having a frame member and a toe retainer that is releasably connected to the frame member. The toe retainer is configured to dorsiflex at least one toe of the user to allow for a dynamic stretch of the plantar fascia and to provide a low load stretch of the Achilles tendon, plantar fascia tendon, deep flexor muscles and calf muscles to relieve symptoms of plantar fasciitis.

Claims

1. A splint comprising:

a frame member; and

a toe retainer releasably connected to the frame member, the toe retainer configured to dorsiflex at least one toe of a user,

12. A splint comprising:

a frame member; and

a toe retainer releasably connected to the frame member, the toe retainer configured to dorsiflex at least one toe of a user,

wherein the toe retainer comprises a strap that has a connector provided at a first end thereof, the connector releasably connected to the frame member,

wherein the strap is configured to attach directly to the at least one toe, such that dorsiflexion of the at least one toe is controlled via the releasable connection between the connector of the strap and the frame member, and

wherein the frame member comprises a stretch adjustment portion having at least one connection point and the connector of the strap releasably connects to the at least one connection point.

13. The splint according to claim 12, wherein the stretch adjustment portion comprises a plurality of connection points and dorsiflexion of the at least one toe is varied depending upon which one of the plurality of connection points the connector of the strap is connected thereto.

14. The splint according to claim 12, wherein the second end of the strap is configured to attach directly to a plurality of toes of the user, respectively.

15. A splint comprising:

a frame member; and

a toe retainer releasably connected to the frame member, the toe retainer configured to dorsiflex at least one toe of a user,

wherein the frame member is configured to generally conform to a top surface of a user'"'"'s foot at a first portion and to a front surface of a lower leg of the user at a second portion, and

wherein the toe retainer comprises a strap that has a connector provided at a first end thereof, the connector connecting to the first portion of the frame member, extending around a front of a toe region of the user and connecting to a foot strap of the frame member underneath the toe region.

16. The splint according to claim 15, further comprising at least one side strap connecting between an upper portion of the strap that extends over the toe region and a lower portion of the strap that extends underneath the toe region.

17. A splint comprising:

a frame member; and
