Robot-assisted vs. Conventional Occupational Therapy of the Upper Limb in Individuals With Cervical Spinal Cord Injury

The goal of this clinical trial is to learn the effects of robot-assisted therapy using the ArmeoSpring on upper limb function compared to conventional occupational therpay in individuals with cervical spinal cord injury (cSCI). The main questions it aims to answer are: \- Which of the two forms of therapy, robot-assisted therapy or conventional occupational therapy, is more effective in terms of improving arm and hand function? The study is designed as a cross-over trial, which means that each participant will receive both therapy forms consecutively, whereas the order is assigned randomly (either robot-assisted therapy first and then occupational therapy, or vice versa). In addition to their clinical routine therapy , participants will: * complete a baseline assessment * practice one therapy form (either robot-assisted or occupational therapy) with one arm for 6 weeks (3 x 30 min per week) * complete a intermediate assessment * practice the other therapy form (either occupational or robot-assisted therapy) with one arm for 6 weeks (3 x 30 min per week) * complete a post assessment * complete a follow-up assessment (if the post assessment was completed prior to 150 days post-injury)
