Abstract: Prosthetic feet that provide for variable and adjustable stiffness are provided. A foot element can include a tongue portion defined or formed by a slot in the foot element that at least partially separates the tongue portion from a remainder of the foot element. The tongue portion can be operably connected to the remainder of the foot member to increase the stiffness of the foot member or operably disconnected from the remainder of the foot member to increase the flexibility of the foot member. The prosthetic foot further includes a mechanism for adjusting whether the tongue portion is operably connected or disconnected from the remainder of the foot member. The mechanism can be selectively actuated to adjust the stiffness of the foot element in dorsiflexion and/or plantarflexion and/or to adjust the degree to which the tongue portion is allowed to flex relative to the remainder of the foot member.

The toe region can include a U-shaped cut out to define a big toe. Various features of the foot element can guide rollover of the foot through the big toe during use. A foot cover can be designed to receive a prosthetic foot including such a foot element. The foot cover can have a region of increased flexibility at a transition between the forefoot region and toe region. The foot cover can also have a padded area extending from the heel region across a lateral part of the arch region and forefoot region.

The device has a continuously knit elasticized fabric layer including a first set of yarns located about a circumference of the device through the first and second regions. The fabric layer has different knit structures in the first and second regions to obtain different elasticity while sharing the first set of yarns so that the first region has a first elasticity, and the second region has a second elasticity greater than the elasticity of the first region. An elastomeric layer secures an interior surface of the fabric layer.

The orthopedic device has various embodiments of strap assemblies for securing components to cuff assemblies.

Abstract: Prosthetic and/or orthotic devices (PODS), control systems for PODS and methods for controlling PODS are provided. As part of the control system, an inference layer collects data regarding a vertical and horizontal displacement of the POD, as well as an angle of the POD with respect to gravity during a gait cycle of a user of the POD. A processor analyzes the data collected to determine a locomotion activity of the user and selects one or more control parameters based on the locomotion activity. The inference layer may be situated between a reactive layer control module and a learning layer control module of the control system architecture.

Abstract: A pad assembly comprises a padding defining first and second surfaces, and includes a first layer being resilient and accessible from the first surface and a second layer being resilient and underlying and secured to the first layer. The first and second removable sections are formed from at least one of the first and second layers and are arranged in a pattern and separated by edge clearances. Each of the first and second removable sections is tearable from the padding such that a residual portion of the removable section remains when at least one of the first and second removable sections is removed from the padding. The pad assembly may include a strap, and a substantially rigid or rigid shell connecting to the padding and strap.

Abstract: A prosthetic foot has a plate-like foot member with a core section substantially defined by one or more layers comprising a first material fiber, an upper section disposed above the core section, the upper section substantially defined by one or more layers comprising a second material fiber, and a lower section disposed below the core section, the lower section substantially defined by one or more layers comprising a third material fiber, where the upper, lower and core sections together define a total thickness of the plate-like elongate foot member. An idealized ratio of the cross sectional area of each section can be determined such that under an applied load provided to the hybrid layup, the ratio of maximum stress of a given section over the flexural strength of that given section is approximately equal for all sections of the hybrid layup. The hybrid layup arrangement can be configured to have a greater strength, but generally the same stiffness, as a similar foot member made of carbon fiber.

Abstract: A vacuum assisted suspension system includes an elongate compression transfer element and a pump housing. The pump housing defines an enclosed space to receive a fluid. At least one wall of the housing and at least one movable wall define a fluid compartment and a non-fluid chamber. The at least one movable wall is connected to the compression transfer element. The compression transfer element causes the at least one movable wall of the fluid compartment to reciprocate in the fluid compartment to increase the volume of the fluid compartment in response to a compressive force on the compression transfer element and enables the at least one movable wall to decrease the volume of the fluid compartment in the absence of a compressive force.
