Saccadic Eye Movements and EMDR Therapy

In EMDR Therapy two different kinds of eye movements are employed.  One is “saccadic” and the other is “smooth pursuit” eye movement.  In saccadic eye movement, the eyes shift back and forth between two fixed targets while in smooth pursuit the eyes are tracking a moving target

Saccadic eye movements are preferred to smooth pursuit tracking in EMDR Therapy

  • Dr. Francine Shapiro’s discovery was based on observation of her own involuntary saccadic eye movements (2001)
  • Repetitive redirecting of attention in EMDR induces a neurobiological state, similar to that of REM sleep” (Stickgold, 2002, p.61) implicating the involuntary saccadic eye movements that occur in REM sleep
  • Compared to smooth pursuit and vertical eye movements, only horizontal saccadic eye movements enhance episodic memory retrieval (Christman et. al. 2003)

  • Saccadic eye movements are easier to perform by younger children and clients with TBI who may have difficulty in crossing the midline which is required in smooth pursuit

  • Once the eyes become habituated to the location of fixed targets, saccadic eye movements are easier to perform since they consume less attentional resource and cause less strain on the eyes than the smooth pursuit


EMDR Therapy Tool Kit

  • SEMS-200, TS-200, Remote control, AC power supply, Heavy duty tripod, Carry Case (Accessory), Portable power supply (Accessory), Portable compact tripod (Accessory/Substitute)

  • Saccadic Eye Movement Simulator (SEMS-200)

            SEMS is a device used to simulate saccadic eye movements in EMDR Therapy.  SEMS consists of detachable optical arms and  the central processor unit controlled by a Remote.  The central processor unit is powered by AC adapter and has outlets for  tactile and audio signals synchronized with the lights. The EMDR Therapy Took Kit comes with all the component devices to  simulate Saccadic Eye Movements (SEMS-200) synchronized with Tactile Stimulator (TS-200) and Audio stimulation                    through Head Phones. The device can be used as a stand-alone tactile/audio stimulator by detaching the optical arms from            the central processor unit. Our unique design simulates saccadic eye movements with least strain on the eyes permitting                        longer processing sessions

  • Detachable optical arms that slide into central processor unit, Interchangeable six colored light filters, Wider lighted target spots (2x1.5 inch) with different colors makes it easier to focus, Change the orientation from horizontal to diagonal by a simple  tilt of the unit, Light, easily disassembled and portable, Operated by a handy remote control, Lifetime warranty on any production/material defects

  • TS-200

            Its cylindrical shape and size makes it possible to hold the Tactile Stimulator in a clasp rather than having to clench it                      reducing the strain on the hand.  The TS can also be cradled in an open palm.  Its waterproof smooth surface makes it

            easy to disinfect with a wipe and hygienic to use client after client. 

  • Cylindrically shaped 5.25 inch long and 1.25 inch wide, Made of cast aluminum, High quality engine, Durable custom designed cable, Non-Porous surface & easy to disinfect, Soft and soothing tactile stimulation without jarring vibrations or noise, Lifetime Warranty

The ideas for SEMS-100 & TS-100 was originally conceived by Dr. Chandra Nagireddy, an EMDRIA Approved Trainer & Consultant and brilliantly engineered and brought to life by Shawn Rife, an Engineer & an Entrepreneur
