The Explorer System can be used for unilateral amputees from amputation height transradially or in case of dysmelia in forearm fittings (according to ISO 8548-2:2020). The system is suitable for persons from 2 years of age. In the case of very young users, we recommend clarifying together with the parents and the doctor whether the child can actually receive the desired benefit from the aid. The activity modules can also be used independently of the macu4 Explorer socket after consultation with the specialist.
