How ddrobotec® can test and assess impairments after ACL injury

Ahead of CASES BIG 2025, the annual meeting of The Chartered Association of Sport and Exercise Science (formerly known as BASES) , we’re shining a spotlight on how ddrobotec ^® can be used for testing, training and assessing impairment after ACL injury.

About ddrobotec®

Launched in the UK back in April 2024, ddrobotec ^® is an innovative smart resistance training system developed by Swiss-based company Dynamic Devices.

ddrobotec ^® is more than a simple leg press or exercise machine. ddrobotec ^® tracks and analyses the interaction between the central and peripheral nervous system with the lower extremities in real-time. Smart data analytics offers performance tracking and measurement of cognitive, sensori-motor and physical performance of the brain, nerves and legs.

To precisely monitor coordination, strength, power and endurance, ddrobotec ^® employs a unique combination of sensors, artificial muscles and high-speed visual feedback.

How ddrobotec® can be used for ACL injury

Impairments	Measurables	Tests	Biomarkers	Insights
Joint instability Compensatory movements	Dynamic knee instability	Stiffness Control	Stiffness control: Deviation between the target and actual knee angles during external disturbances Left/Right asymmetry	Lower extremity intramuscular coordination stiffens and stabilises the knee angle.
Loss of knee control Joint instability Delayed reaction time	Proprioception in the lower extremities	Position Sense	Position sense: Deviation from the previously perceived knee angle Left/Right asymmetry	Neuromotor control and proprioceptive awareness for lower extremity joint positioning.
Reduced functional strength Difficulty with high-impact activities (e.g. jumping, sprinting, squatting) Compensatory movement Prolonged recovery	Concentric power	Real Power	Peak power Peak speed Rate of power development Left/Right asymmetry	Lower limb concentric power. Ability to generate force and speed concentrically without utilisation of stretch-shortening cycle.
Difficulty with high-impact activities (e.g. jumping, sprinting, cutting) Slow reaction time Limited jumping and landing ability Reduced speed and acceleration	Ballistic strength	Reactive Power	Peak power Rate of power development Left/Right asymmetry	Lower limb ballistic strength, efficiency, and utilisation of stretch-shortening cycle. Pre-planned agility.
Reduced shock absorption Decreased explosive power Delayed neuromuscular response Altered landing mechanics	Landing ability and reactive strength	Negative Power	Plyometric reaction time Plyometric power index Left/Right asymmetry	Quick reaction to sensory input, efficient force absorption and rebound capability. Reactive unplanned agility.
Reduced functional strength Altered movement patterns Decreased joint stability Impaired proprioception and balance Delayed rehabilitation progress	Strength in the lower extremities	Force Power	One repetition maximum (1-RM load); 80% of estimated maximum force Left/Right asymmetry	Maximal lower limb strength through Force-Velocity (F-V) profiling.
