Practical Advantages
TThe kBox offers everything from low force, low speed training up to high forces, power training and the possibility of everything from pure concentric contractions to eccentric overload.
- Safe, ergonomic , and maximally silent training with minimal risk of injury
- With its small and portable size, the kBox also fits easily into more compact clinics or even the patient’s home when convenient.
- The kMeter lets you monitor your patient’s power output, adjust training load, and track their progression over time.


Physiological Advantages
Variable resistance controls force output for a safer, more effective workout with reduced injury risk. It strengthens muscles through the full range of motion and seamlessly accommodates rehabilitation needs.
- Adjustable ROM prevents your patient working beyond certain angles, a common requirement during various rehabilitation pathways. (Watch video).
- The kBox harness distributes pressure evenly across both shoulders and reduces torque on the lower back. This ensures safer lifting, particularly for patients new to squatting or functional lower limb exercises, helping to prevent injuries due to poor technique.
- Eccentric load is key for treating tendinosis and kBox flywheel training simplifies its application across various exercises.
- Convincing examples include studies eccentric training in tendinopathy (Murtaugh & Ihm 2013), eccentric training for elderly (Gault & Willems 2013) and flywheel training with elderly (Onambele 2008).
Applications
Some examples of applications of the kBox in rehab settings include:
- post-operative rehabilitation after anterior cruciate ligament (ACL) reconstruction (read more),
- rehabilitation of tendinopathies,
- prevention of recurrent injuries, or prehab,
- treatment of patellofemoral knee pain syndrome, and
- adapted training during periods of injury.
Flywheel training on the Exxentric kBox is already being utilised by rehab clinics in the Netherlands, Sweden and the UK, with several other countries following close behind. The kBox is also in use in sports medicine for rehab and injury prevention, including in European elite football teams and cycling, as well as emergency services.
