Early mobilisation robot

A tilt table with integrated robotic leg drive. The patient is brought from lying towards upright in controlled increments while the legs are cycled through a stepping pattern. The leg movement is not decorative: it drives the calf muscle pump, which keeps blood returning to the heart and substantially reduces the fainting that plain tilt tables cause.

So a patient who could not tolerate being sat up can often tolerate 60 to 80 degrees on this device 1.

Patients in the early phase after severe stroke, traumatic brain injury, spinal cord injury or prolonged intensive care — anyone who has been in bed long enough that standing has become physiologically difficult. Also patients with disorders of consciousness, where upright positioning and leg movement are part of the stimulation programme.

It requires cardiovascular stability within defined limits, no unhealed lower limb fracture, and no deep vein thrombosis that has not been treated. Blood pressure and heart rate are monitored throughout and the table is lowered on protocol, not on judgement alone.

Prolonged bed rest causes rapid bone loss, muscle loss, circulatory deconditioning and joint stiffness, and it is the reason many patients are weaker at the end of a hospital stay than the original injury accounts for. Time upright counteracts all four.

This is a bridge, not a treatment in itself. It exists to bring a patient to the point where real gait and strength work can start.

It brings a patient upright gradually while moving the legs, which allows very early mobilisation in people who cannot yet tolerate sitting up. The leg movement helps maintain blood pressure during the tilt.

This matters because the losses of immobility — muscle, bone, circulatory regulation, pressure areas — begin within days, and waiting until someone can stand costs more than it saves.

The clearest finding concerns tolerance of being upright. In a small crossover trial in nine patients who were still unconscious after brain injury, six had near-fainting episodes on a conventional tilt table but not on a tilt table with integrated stepping 2. A meta-analysis of nine randomised trials with 347 patients found the stepping tilt table safe for people with neurological injury, with some reduction in spasticity after stroke but no clear gain in muscle strength 3.

Its effects on function, walking, balance and level of consciousness remain uncertain, and the trials are of limited quality 3. Gains seen in studies without a comparison group cannot be separated from natural recovery and the rest of the rehabilitation programme 1.
