Laser Pointer For Parkinson’s

Canada: Laser Used To Help Parkinson’s Patients Walk More Steadily Now Available

Laser pointer helps Parkinson’s Disease Patient

According to the manufacturer, “Path Finder is a shoe attachment that provides visual laser cues for patients suffering from Freezing of Gait , a symptom of Parkinsons and other neurological disorders, severely impacting gait and quality of life. These visual laser cues are in the form of horizontal lines, prompting the individual to take steady steps with both feet, one after another. This hands-free device is meant for individuals with unsteady gait, and can be used to gain confidence, regain mobility, prevent falling and improve quality of life.”It uses a green Class 2 laser, meaning the light is considered safe for normal operation. According to LaserSafetyFacts.com’s page on Class 2 lasers, “It normally would not harm an eye unless a person deliberately stared into the beam.”The idea for Path Finder came to inventor Lise Pape in 2014, after watching her father struggle with Parkinson’s. She became aware that visual cues such as lighted canes had been used with some success to help trigger a normal step response. She started work on a prototype in 2014, and the product came to market in 2017. It has won more than fifteen awards, including the AXA Health Tech and You Award in the UK in 2016 and Vodafone TechStarter in the UK in 2019.

The Story Behind The Lasercue

We were inspired to design the LaserCue by Michael J. Fox. He encouraged us to make a version of our LaserCane® that can be retrofitted to any cane so you can benefit from this technology while using the cane of your choice. Through our collaboration we have created the LaserCue module that allows you to enjoy an easier stride, while choosing a cane to fit your needs and personalityfrom classy to bold, wood or metal.

We are proud that with every purchase of the LaserCue, a donation is made to the Michael J. Fox Foundation for helping in finding a cure for Parkinsons disease.

This is a breakthrough product for Parkinsons patients with freezing issues. I use it often and it always works great. I really think that this product could change and possibly even save lives.

-Michael J. Fox

Laser Cueing Has Been Proven Effective in Clinical Research

This study identified that the LaserCane was the most effective cueing device for people with Parkinsons disease compared to the other interventions tested.

Allied Health Research Unit, University of Central Lancashire, Preston, UK.

The current study demonstrates that adding a laserlight visual cue to a cane or walker can lead to a modest reduction in FOG and may substantially reduce the frequency of falls in PD patients with FOG .

What Is Freezing Of Gait

This Laser Pointer Stablizes The Laser From Hand Tremors

Freezing of gait is an abnormal gait pattern that can accompany Parkinsons disease as well as other parkinsonian disorders in which there are sudden, short and temporary episodes of an inability to move the feet forward despite the intention to walk. In a sense, youre stuck. This results in the characteristic appearance of the feet making quick stepping movements in place. However, while the feet remain in place, the torso still has forward momentum which makes falls unfortunately common in the context of freezing of gait. For some, these episodes can simply be frustrating, annoying and perhaps embarrassing for others freezing of gait can become incredibly disabling and lead to injury.

Freezing of gait episodes tend to occur least often when walking on an unobstructed, straight path. Any deviation from that can induce freezing for example, when you first try to start walking, when you go to make a turn, or try to navigate around obstacles or through narrow spaces any of these can cause you to get stuck.

The particular triggers for one person may be different than for another. An episode is typically very brief, often lasting only 1-2 seconds, although they can last longer. Freezing of gait can be affected by anxiety, so if a person feels rushed , freezing may be particularly prominent.

Can Laser Shoes Help People With Parkinson’s Walk

Many people with Parkinson’s disease have freezing episodes when they walk. They suddenly come to a standstill and even though they want to move, they can’t.

One London-based entrepreneur has come up with a solution – lasers fitted to their shoes.

What Does It Do

This laser light accessory provides visual and auditory cues, providing something to focus on that would naturally initiate the ability to walk again. It isnt uncommon for those with PD to suffer from reoccurring freezing episodes, theyre random at best and theres no real warning for when theyll come on. When the laser light accessory is attached, there are buttons near the handle to initiate the laser, after ten minutes of idle use, the laser will turn off automatically.

The theory behind these laser mechanisms is that the visible cue of the laser will bypass anything the brain might be telling the legs, resulting in the ability to walk towards the light. In some cases, it might not always work as there is no treatment for these freezing episodes, but it does help initiate the process of walking again.

While its very possible to simply just tape some laser pointers to your walker, we recommend using the actual product as it has better programming and is more functional to those with disabilities. Although, keeping a pocket laser here and there definitely couldnt hurt!

Limitations Side Effects And Long

Baltuch cautions, however, that focused ultrasound thalamotomy is not without risk or side effects, there are limitations, and there are not yet long-term studies.

  • Side effects: Side effects include difficulty walking or unsteadiness following the procedure, along with tingling or numbness in the lips or fingers. Most issues resolve within months.
  • Limitations: Currently, only one side of the body can be treated. Earlier forms of surgical ablation sometimes resulted in speech difficulties, so for now, the FDA has limited treatment to one side of the brain. The side that controls the patients dominant hand is usually targeted. INSIGHTEC is exploring bilateral treatment in medical centers outside the U.S. In addition, while treatment can reduce or eliminate tremors on one side of the body, it does not stop other symptoms of Parkinsons or slow disease progression.
  • Long-term studies: Because five- and 10-year studies have not yet been conducted, We dont yet long-term effectiveness of focused ultrasound thalamotomy for tremor-dominant Parkinsons and essential tremor, says Baltuch. The published data show that this may not be as effective in tremor reduction as, potentially, deep brain stimulation can. And, although its non-invasive, youre still making a thermal lesion .

Nir For Parkinsons Disease

Mainly due to the existence of effective toxin-based in vitro and in vivo models, there have been considerably more reports on the beneficial effects of NIr for Parkinsons disease .2). The first studies to report neuroprotection by NIr after parkinsonian insult demonstrated that NIr treatment reduced cell death, increased ATP content and decreased levels of oxidative stress in rat striatal and cortical cells exposed to the parkinsonian toxins rotenone and MPP+ in vitro . In cultures of human neuroblastoma cells engineered to overexpress -synuclein, NIr increased mitochondrial function and reduced oxidative stress after MPP+ exposure . Further, in hybrid cells bearing mitochondrial DNA from Parkinsons patients, mitochondrial movement along axons improved substantially after NIr treatment, with movement restored to near control levels .

How Does It Help Parkinsons Patients

Parkinsons disease occurs as a result of the death of certain cells in the brain. These cells produce a chemical called dopamine, which is a neurotransmitter responsible for controlled movement. It is due to the deficiency of dopamine that severely affects the brains ability to send movement signals to different parts of the body, including the legs. As a result, the patients get tired quickly and experience trouble walking. Most often, they stop suddenly whilst trying to step forward, this is called freezing. This sudden freezing can be hazardous for patients as it can make them fall and cause serious injuries.

The basic science behind the In-step LaserCane is the projection of visual cue in the form of a laser beam light, which sends a message to the brain to allow the leg to move forward.The laser line automatically projects right in front of the leg as soon as the cane comes in contact with the ground. This bright laser line serves as a safe, obstacle-free visual cue, which prevents falling and help Parkinsons patient to begin the step by stepping over the line. The laser line disappears when the cane is lifted and reappears when it touches the ground again for another step thus allows the patient to step after step and restore the normal walk.

Studies conducting PBM via transcranial, intracranial, systemic irradiation as well as whole-body irradiation approaches in PD models were included. Studies performed on ex vivo or in vitro , as well as clinical trials, were excluded. Additionally, studies conducted on intact animals were excluded from our review. Moreover, non-English language publications and studies involving NIR spectroscopy and conference papers were excluded.

Nir Therapy In Alzheimers And Parkinsons Disease Patients: Can It Work

Guiding light for Parkinson

The key question that still remains is whether NIr therapy can be neuroprotective in humans. In order for maximum effect, the primary goal would be for sufficient NIr signal to reach the main zones of pathology, to elicit a protective, or reparative effect within damaged cells a secondary goal would be for the NIr signal to also trigger systemic neuroprotective factors, for example circulating cells or molecules .

The issue of NIr reaching the zones of pathology is of most concern in humans. There are no such concerns when there are few or no tissue barriers, as in the culture dish , the retina or in the mouse brain . But can NIr be effective when there are many intervening body tissues, namely skin, thick cranium, and meninges, and brain parenchyma, as in humans?

Previous studies have estimated that NIr can be measuredthrough body tissuesat a distance of 2030 mm from the transmission source , albeit with a considerable dissipation of signal . For example, Moro et al. have noted that at a distance of 10 mm through brain parenchyma, the NIr signal is < 1% of that emitted from the source. They estimated a 65% reduction of signal across each millimeter of brain tissue.

Treating Freezing Of Gait For People With Parkinsons

Freezing of gait episodes often occur when a person is under-medicated and can improve with increased amounts of their PD meds, usually carbidopa/levodopa. However, as mentioned earlier, the brain abnormalities that lead to freezing of gait are very complex, so giving more dopaminergic medication is only part of the solution. In fact, some people have what is referred to as ON freezing. This means that freezing of gait episodes occur even when other PD symptoms are well treated with their medication regimen.

Cueing, or the introduction of an external sensory stimulus to facilitate movement, has been identified as a way to break a freezing episode. Terry Ellis, PhD, PT, NCS, Director of the APDA National Rehabilitation Resource Center at Boston University, and Tami DeAngelis, PT, GCS, compiled this list of cues that can be used to get out of a freezing episode:

Summary:
A patients discovery that an everyday laser pointer helps him walk may point the way toward an effective remedy for a common and frustrating symptom of Parkinsons disease.

A patients discovery that an everyday laser pointer helps him walk may point the way toward an effective remedy for a common and frustrating symptom of Parkinsons disease. The patients physicians at the University of Rochesters Strong Memorial Hospital are presenting the results of a study involving just a few patients at this weeks meeting of the American Academy of Neurology in Toronto. While the small size of the study should make patients and doctors pause before assuming the treatment will help, the authors say neurologists would do well to have a laser pointer handy to let patients give it a try.

The simple device seems to help patients overcome freezing episodes, where patients legs literally freeze in place as theyre trying to walk. For about 30 percent of Parkinsons patients, this sudden transient freezing is one of the most difficult symptoms of the disease. The episodes can last for seconds or even several minutes. Some patients experience only momentary hesitation occasionally, while for others the episodes occur dozens of times a day, making almost any simple movement from room to room a laborious task taking several minutes.

Brain surgery for Parkinsons disease is done to balance the activity in certain areas of the brain that control physical movement. The surgery can involve placement of a stimulator device or creation of a surgical lesion in the brain.

The areas of the brain that are affected by Parkinsons disease are very small, and they are located deep within the brain. These procedures are done with precision and often with imaging guidance so your surgeon can see the structure of your brain with real-time pictures during the surgery.

The majority of the studies reporting beneficial effects of NIr treatment in Alzheimers disease or dementia have been in transgenic animal models, in particular those displaying -amyloid , or tau pathologies .1). In general, with either acute or more chronic NIr treatment, these studies have reported reductions in -amyloid plaques, neurofibrillary tangles of hyperphosphorylated tau protein, inflammation and oxidative stress, together with increased ATP levels and improved overall mitochondrial function. In addition, NIr reduced the characteristic cognitive deficits associated with the CD1 and APP/PS1 transgenic mouse models. One in vitro study reported that, after internalization of -amyloid into human neuroblastoma cells, NIr treatment increased ATP levels and overall cell number, while reducing -amyloid aggregates .
