Hand Therapy with RehaDigit

RehaDigit from Hasomed

RehaDigit can reduce the muscle tone and increase mobility in the fingers of the hand. Following a stroke, brain inuryor 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.  RehaDigit 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 Rehadigit

RehaDigit 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 allowRehaDigit 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 RehaDigit 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 RehaDigit stretches and massages the fingers. Integrated vibration relaxes tight fingers in a safe and effective way. RehaDigit has a unique operating principle - most devices focus on movement whereas RehaDigit also targets the sensorimotor system. Studies have confirmed the effectiveness of the device.

Indications for Usage

RehaDigit 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

Contraindication for RehaDigit 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
  • fixed fingers

Features

RehaDigit is a CE marked Class II medical device.
