MultiMotion Dynamic Corrective System Joints

Basko Healthcare supplies high-quality orthopedic aids for the professional healthcare sector with sales markets mainly in Western European countries and the United States. Basko’s portfolio includes a range of specialized components for orthoses, of which the MultiMotion Dynamic Corrective System Joint hinges form an important part. These system hinges are specifically aimed at the treatment of correctable contractures and find wide application in orthoses for both children and adults.

Functionality of the MultiMotion correction joint is based on the LLPS principles (Low Load Prolonged Stretch). This process of gradual, precise and evenly applied tension, stimulates the growth of the shortened tissue and increases joint mobility. The use of a low, ongoing correction force extends altered tissue, thereby increasing the functionality of the joint.

Basko Healthcare approached Helder-id with the challenge to modernize the existing range of MultiMotion system hinges, especially looking at smaller and flatter hinges.

Search for the right spring

There has been a desire to expand the program with a smaller and perhaps also flatter hinges. Unfortunately, previous attempts to generate the desired spring force using a smaller diameter flat coil spring did not have the desired result. It turned out that the desired spring dimensions were very close to the theoretically physically achievable. And most spring manufacturers were unable to produce these springs at an acceptable cost. Helder-id therefore set up a sourcing process to find a suitable supplier. Several prototypes were made and tested to find out whether smaller and flatter versions of the hinge were at all feasible.

Updated design

When the right spring manufacturer was finally selected, Helder-id developed a completely new design with an updated look & feel that is much better in line with the current market needs. The plastic enclosure of the previous model was replaced by a mostly metal version. By using stainless steel, the housing could be much more compact, and this also gave a much higher quality appearance. This was further enhanced by the smooth easy-to-clean finish and the flush mounted window for reading the spring setting. The new design was therefore ultimately applied to update the entire MultiMotion series.

FreeMotion joints

The MultiMotion dynamic corrective system is mostly applied for orthoses in a combination of two components: the corrective joint and a free motion joint. Both the corrective and the free motion joints are available in different sizes and different versions, including pre-drilled and integrated straight or T-bars models. Helder-id took care of the design for the entire new program.

Easy integration

The new range includes different sizes with many different options to be used by orthopedic technicians for the treatment of wrist, knee, elbow and ankle joints, both for children and adults. The torque output of the hinges can be easily adjusted to treat the contracture in either flexion or extension, on either the left or right side, with a range of motion from +120° to -120°, using adjustable flexion and extension stops with 12° or 14° increments.

Animated instruction videos

Helder-id also took care of the production of a series of instructional videos to illustrate the working of the MultMotion joints and its various parts. Also, the use of the locking mechanism and the options for setting the torque output and the flexion/extension stops are further clarified. The videos were all rendered and animated in Keyshot and post-processed using Adobe After Effects.
