Simply Effective Hand Therapy with DigiTrainer
DigiTrainer (formerly RehaDigit) can reduce the muscle tone and increase mobility in the fingers of the hand.
Following a stroke, brain injury or spinal cord injury, for example, the muscles and soft-tissues of the hand can become tight and the sensory pathways disrupted.
In order to recover lost tactile sense and to trigger new movement capabilities, intensive rehabilitation is needed and this should start as soon as possible following the injury.
For example, with a cervical level spinal cord injury it is important to avoid complications by early positioning, stretches and oedema management. The hand is perhaps the most important resource after the brain in these cases so the hands must be kept supple if we are to have a chance of developing functional activities. The DigiTrainer makes intensive rehab possible.
DigiTrainer provides both motor and sensory rehabilitation in a simple and effective manner. Through a series of finger-rolls the patient's fingers are alternately bent and stretched (flexion/extension of the finger joints). The specially designed motor induces a slight vibration into the hand and this supports the relaxation of the finger muscles.
Hand Therapy with DigiTrainer
DigiTrainer mobilises hands that have limited finger movements and prevents muscle and tendon shortening. The objective of treatment is the improvement of your patients‘ motor and sensory functions.
Various hand rests, types of vibration and rotation speeds allow DigiTrainer to be adjusted according to the needs of each particular patient. The vibration improves the sensory and circulation aspect of the hand and reduces spasticity. The motorised movement moves and stretches every digit whilst ensuring the correct position of the fingers.
What it does
Check out the video below to see DigiTrainer in action. The unit accomodates left or right hands of various sizes and allows easy programming via a touch screen interface. The therapist can control the specific nature and speed of the movement as the DigiTrainer stretches and massages the fingers. Integrated vibration relaxes tight fingers in a safe and effective way. DigiTrainer has a unique operating principle - most devices focus on movement whereas DigiTrainer also targets the sensorimotor system. Studies have confirmed the effectiveness of the device.
Overview of the main functions:
works for the left and the right hand
adjustable rotation velocity
adjustable vibration frequency
continues or periodic crescendo and decrescendo vibrations
ergonomic hand rest (height adjustable)
usage via touch screen
therapy time: 5-30 min
Indications for Use
DigiTrainer can be used for the following indications:
passive bend and stretch movement of the II-V fingers in the rehabilitation of patients with hemi- and tetraparesis from moderate to strong paresis of the upper extremity
for example, after stroke, paraplegia, traumatic brain injury, M. Parkinson or joint injuries
for patients without distal activity of the wrist and finger flexors
incomplete and complete motoric paraplegia after spinal cord injury
for patients with spasticity in arms, low blood circulation and impaired hand mobility
for patients with functional loss after injury or surgery
Contraindications for DigiTrainer include patients with:
fully developed shoulder-arm syndrome
acute arthritis in finger joints, thumb joints and/or wrist
severe contractures of the finger joints, thumb joints and/or wrist
acute disorders requiring special treatment of fingers or hand (e.g. tendinitis)
massively swollen hand
allergic exanthema of hand
DigiTrainer is a CE marked Class II medical device. The items included are 1 DigiTrainer, 2 adapter plates for hand rest (25mm and 20°), 1 power supply and appropriate cable and 1 user manual
Expected Life 3722 therapy hours
