DeltaTwist

• With the loss of the foot and part of the leg, the amputee has lost important proprioceptors and muscle groups which, through their interplay, ensure a harmonious gait pattern under physiological conditions. 
• The DeltaTwist® shock absorber, which also features a torsion function, is able to compensate for this loss to a certain degree. 
• Its shock absorbing function and torsion function provide more safety, mobility and comfort. 
• With its integration into the prosthesis, a more symmetrical gait pattern can be achieved. 
• Instabilities can be eliminated and compensating movements are reduced. 
• It relieves the locomotor system and residual limb. 
• Both shock absorption and the torsion function can be adjusted individually and independently by means of various elastomer components of different durometers.
• This allows the specific movement pattern of every amputee as well as biomechanical insights to be taken into account. 
• When needed, interior or exterior torsion can also be suppressed using the rotation locking segment (see accessories). 
• The DeltaTwist® can be used for transfemoral as well as transtibial prostheses. 

Indications:

• Unnatural, asymmetrical gait pattern in terms of the rotation in transversal plane (around the body’s longitudinal axis)
• Overloading of the residual limb and locomotor system due to impact load and shear forces
• Significant sensibility against impact loads such as formation of oedema on the residual limb
• Pronounced dynamic gait patterns
• Frequent torsion stress (rotational movements) at work and during leisure activities
