Light Therapy

Lightwave Stimulation (LWS)

In addition to its role in vision, light exerts strong effects on behaviour. Its powerful role in the modulation of mood is well established, yet remains poorly understood.

There are physiological mechanisms, such as the pathway for light’s effects on the endocrine system through the retino-hypothalamic tract, which provide a scientific basis for beginning to understand the critical ways that light influences performance.

Our Light Therapy programme, known as Lightwave Stimulation (LWS), is intended to address light processing deficiencies which often seem to correlate with various learning, behavioural, reading and social difficulties. These may have profound effects on physical and emotional well-being.

The literature on coloured light indicates both the importance of light for the functioning of the body and its usefulness for psychological and emotional healing and light has a long history of therapeutic use. The more modern pioneers include Edwin Babbit, Auguste Rollier, Niels Finsen (Nobel Prize winner), Dinshah Ghadiali, Harry Riley Spitler, John Downing and Jacob Liberman.

When Lightwave Stimulation (LWS) has been used by us, many clients have reported improvements that include:

  • Increased alertness
  • Improved concentration
  • Improved sleeping
  • Eating or toileting patterns
  • Reduced tantrums and aggressiveness
  • Reduced impulsivity or overactive behaviour.

Who We Help

We have frequently found that constricted visual fields of awareness are related to inadequate functional visual abilities and overall learning and performance deficits.

Striking changes in quality of test results, symptom reductions, performance, behaviour and mood can occur as a result of Lightwave Stimulation (LWS).

Lightwave Stimulation (LWS) therapy may be helpful in association with:

  • Low self-esteem
  • Poor sleeping patterns
  • Educational difficulties
  • Anxiousness
  • Socialisation difficulties
  • Visual perceptual problems and reading difficulties
  • Overactive or impulsive behaviour
  • Eating problems, faddy eating
  • Sadness

Therapy
Following an assessment a personalised protocol is prepared. Lightwave Stimulation (LWS) involves looking at a low intensity, pulsed, coloured light, emitted by a Lumatron or Photron machine.

  • The programme normally consists of two, 20-minute sessions each day for ten days.
  • During treatment the client sits comfortably in a darkened room.
  • The programme is individually tailored to each client.
  • Lightwave Stimulation (LWS) is often used in combination with Auditory Integration Training (AIT).
  • Wherever possible, we measure colour visual fields and visual perceptual profiles before and after treatment.

How Light Helps
It is evident to most of us that light is required for vision, since without light we cannot see. What is not always recognised (but has been widely demonstrated) is that light also influences our eating and sleeping patterns, circadian rhythms, hormone production and regulation, emotional state and libido.

When light rays strike the retina of the eye, they are converted into nerve current, sometimes termed photocurrent, which travels via the optic nerve not only to the visual cortex but also to many other brain centres. These include the pineal gland and the hypothalamus, the brain’s master controller. Light thus effects not only our vision but also profoundly influences effective functioning of these other systems on which physical and emotional well-being depend.

KEY:
Light received by the eye is converted to neural signals that pass via the optic nerve to these visual and nonvisual pathways. POT = Primary optic tract. RHT = Retino-hypothalamic tract. LGN/IGL = Lateral geniculate nucleus / Intergeniculate leaflet. SCN = Suprachiasmatic nucleus of the hypothalamus. PVN = Paraventricular nucleus of the hypothalamus.IMLCC = Intermediolateral cell column of the spinal cord. SCG = Superior cervical ganglion. CRH = Corticotropic releasing hormone. ACTH = adrenocorticotropic hormone.

The rationale of Lightwave Stimulation (LWS) is that it stimulates the non-visual receptive system to respond more efficiently and use available light more effectively. In turn this can lead to improved mental, emotional and physical well-being resulting in enhanced performance in many areas.

Please Note: Lightwave Stimulation (LWS) is not a medical treatment.

Although our experience shows that clients have experienced a wide range of improvements in social, emotional, behavioural or academic performance following our therapies we do not claim to diagnose, treat, cure or prevent any disease or any other physical or mental disorder and always recommend that clients consult their medical practitioners as appropriate and do their own research before commencing any of our therapies.

Some further background information on the use of coloured light through the eyes.
Not all retinal (light-sensitive) nerves in the eyes serve vision. Some connect the retina directly to non-visual brain centres such as the hypothalamus and pineal gland. These centres influence electrical, chemical and hormonal balances which affect many body functions including vision. Years of clinical application and research have demonstrated that certain selected light frequencies (colours), applied by way of the eyes to these centres, can produce beneficial results in the body.

Controlled clinical studies by Dr Robert Michael Kaplan (1983) and Dr Jack (Jacob) Liberman (1986) demonstrated that the usual result of this relatively short-term treatment is improvement in visual skills, peripheral vision, memory, behaviour, mood, general performance and academic achievement.

Their research showed that large numbers of children with learning problems may have reduced visual fields. During and after photo-therapy they demonstrated improvement of peripheral vision and visual skills. Control subjects who did not receive therapy showed no improvement in their peripheral vision, symptoms or performance.

In 1986 Jack (Jacob) Lieberman, author of Light Medicine of the Future, published his study which documented the therapeutic use of light with a wide range of difficulties and how the presence of these difficulties correlated with restricted visual field of awareness. He also showed how expanding these fields with the use of coloured light therapy correlated with improvement in performance for those with those difficulties.

Since then there has been a surge in research dealing with the effects of the ‘energetic action’ of light via the retino-hypothalmic pathway which has provided evidence for the influence of light via the eye on the human organism.

In the past few years convincing evidence has emerged of, previously unknown, intrinsically photosensitive Retinal Ganglion Cells (ipRGCs). These form a third, light sensitive receptor system in the eye and are not involved in vision. They are additional to the rod and cones This discovery has provided a further rationale for the therapeutic use of light through synchronisation of the mammalian circadian rhythms with environmental time by modulating retinal input to the circadian pacemaker-the suprachiasmatic nucleus (SCN) of the hypothalamus.
