Until recently, the hospital bed was merely considered as a passive tool aimed at providing the patient with a place to sleep and rest. In time, the hospital bed evolved into a device designed to assist health practitioners: a first fundamental step was replacing with an electric motor the manual activity necessary to mobilize the patient, decreasing personnel workload.
BTS ANYMOV completes the technological evolution introducing a generational leap: the hospital bed becomes a robot for patient focused mobilization, performing the motor therapy directly in the hospital bed, as the first rehabilitation stage following a stroke or a traumatic brain injury event. Almost all the patients in post-stroke or post- traumatic brain injury condition show mobility deficits. Mobilization during the acute phase represents a key factor for a successful rehabilitation.
BTS ANYMOV is the only robotic device beneficial for patient rehabilitation, even when un-cooperative, directly in the hospital bed.
Robotic rehabilitation, directly performable in the hospital bed
BTS ANYMOV is a rehabilitative robotic hospital bed that permits a specific andrepeatable training made of gradual passive exercises. It allows an active, assisted, segmented and multi-segmented mobilization of hip, knees and tibiotarsal joints, through active and against-resistance exercises, coherently with patient’s possibilities.
It is made of 4 movable sections using high precision motors: the whole bed base can be controlled in lift and lateral movement thanks to telescopic pillars; the back can be inclined up to 90°; the lower limb dedicated bases allow hip abduction-adduction movements.
The tibiotarsal joint dorsi-plantaflextion and the knee flexi-extension are actuated by two dedicated motors, presenting clutches on guides placed under the lower limb bases.
An air compressor, providing resistance related to the patient’s push force, is used for the active reinforcement exercises. The same air compressor can be by-passed by the compressed air normally provided in hospital rooms. The particular attention to design and production guarantees the highest standard of operational safety, for both the therapist and the patient.
Combined functional evaluation
During the rehabilitation process, the EMG data acquisition is an effective tool that provides important clues about the patient’s recovery potential. Data from the EMG system can be evaluated as to how and when the patient is trying to generate movement (during active exercises) and also the presence of muscular activity in the passive mobilization phases.
BTS ANYMOV optionally integrates, a totally wireless surface EMG system provided with protocols for the acquisition of several muscle configurations, according to the exercises performed in bed.
1) Knee flex/extension: Evaluation of 3 channels (muscles) for each limb: Vastus Lateralis, Recto Femoris and Semitendinosus.
2) Foot flex/extension (dorsi/plantar flexion): Evaluation of 3 channels (muscles) for each limb: Tibialis Anterior, Gastrocnemius (Medialis or Lateralis), Soleus.
The system automatically provides a structured report showing the concept of muscle contraction intensity and the evidence of muscle contraction work. Specifically the index provides understanding as to muscle activity, quantifying it and consequently monitoring it during the patient follow up for evaluation of progress.
