Introduction

There are many neurodegenerative disorders that have one main occuring symptom in common. Tremors. These tremors have a unknown cause, for example Parkinson’s disease, paraneoplastic syndrome, extrapyramidal syndrome and Idiopathic parkinson. It is very difficult to determine which disorder is related to which tremor. A recent report of the Public Health England shows trends in death numbers of neurological diseases in England between 2001-2014. Mortality associated with Parkinson’s disease and other similar neurodegenerative disorders has increased substantially between 2001-2014. (Darweesh et al., 2018) Since neurodegenerative diseases significantly decrease the quality of life and the incidence is high and still rising, helping these patients becomes of increasing importance for our society.

These neurodegenerative disorders cause tremors with differents stages and different rates that affects a patient in their everyday life. Tremors can be caused by different malfunction in the neurons in the part of the brains. This causes difficulties in controlling movements. Tremors worsen because of stress or anxiety and can also cause Bradykinesia; slowed movements, which can cause feelings of tiredness and weakness. This causes a shuffling way of walking and falling since they cannot adjust their footing quickly enough. Moreover, this causes difficulty when buttoning clothes, brushing their teeth or typing something. They can suffer from decreased movement and range of motion due to muscle stiffness, which causes discomfort. Determining the disease is of high importance, since the health risks of each disorder differs. Also a lot of these disorders have serious tremors that contribute to difficulties in maintaining everyday life activities.

The problem we want to address is to distinguish which tremor related to which disorder by a soft mechanical sleeve. Since it is essential to determine the disorder, because of medication and health risks differs per disorder. Patients with tremors therefore could benefit from a personalized mechanic soft sleeve that would measure the amplitude and frequency of the movements which the tremors create. By these measurements, the sleeve makes it possible to determine the disorder beforehand. Which would result in time and resources to diagnose a disorder with tremors, since specialists are less needed.

Problem statement

"Diagnose similar diseases where tremors occur, by distinguishing the different kinds of tremors based on the amplitude and frequency of these tremors. A doctor can prescribe a patient to wear a sleeve that uses sensors and the model we produced to store data for the doctor to read. Based on this data, a diagnosis can be determined without going to specialists."

Objectives

- Help family medicine doctors diagnose a patient correctly without the help of specialists

- Make diagnosis of tremor diseases quicker and easier

- User-friendly

- Design should be appealing to age demographic (50+)

Users

Primary users

The primary users are the primary family medicine doctors. The problem that they face is that there aren’t any medical tests to identify tremor-related diseases. As such it is not always as clear what disease a patient may have when they are in the beginning stages. They have to work with symptom-based judgment. Even though the main symptom that we are looking at is the same: Involuntary limb movements, the types of medication differ from each other. That is why it is of great importance to come to the right diagnosis right away. With the help of the sleeve, the family medicine doctors have an additional measuring tool to help to conclude the right diagnosis.

The second primary users are the patients that suffer from an early stage tremor-related disease. As said previously, the sleeve is useful in getting to the right conclusion. This prevents cases of misdiagnosis which would result in taking the wrong medication. Taking the wrong medication can be very bad for someone’s general health and it can also cause tedious side effects. Furthermore, the sleeve prevents having to go to a specialist. This can save a lot of money and can also save time.

Secondary users

Secondary users of the sleeve are the companies that create the product. Eventually, if there is a high enough demand for the product, companies will be producing the sleeve. New technologies such as the sleeve may create good business opportunities for both well-established companies and for newer companies.

Tertiary users

The tertiary users are the neurologists. In case of suspicion with a disease caused by a neurological issue, the patient is normally send to a neurologist. The goal of the sleeve is that family doctors would already be able to accurately diagnose patients with tremors being a result due to neurological causes without the help of neurologists. This has a negative impact on neurologists as in this case they would lose a portion of their patients.

Product

The product will be a sleeve. This sleeve will consist of a gyroscope, an accelerometer, and an Arduino. The sleeve uses a model to process the data of the tremors and converts it into a frequency and amplitude spectrum.

Requirements

The requirements of the product are separated for the two primary users

Requirements for family doctors

• The sleeve needs to be able to accurately measure the frequency of the tremors

• The sleeve needs to be able to accurately measure the amplitude of the tremors

• The sleeve needs to be able to use sensor data to compute a model

• The sleeve needs to be able to send data wirelessly to the computer or phone of the doctor via an app

Requirements for the patients

• The sleeve needs to be easy to equip

• The sleeve needs to be comfortable (e.g. by size, weight and feeling)

• The sleeve needs to be useful for a diagnosis

Progress of Project

This project started with developing a soft skeleton to help the physically disabled. Feedback on this was that this subject was too broad for the scope of this class, and not focused on a relevant user problem. The focus then shifted from doing literature research on exoskeletons to finding an important and interesting user problem that we can try to find a solution for. Soft exoskeletons can be used for extra stabilization and support, which is how we thought about Parkinson’s disease.

The most well-known symptom of Parkinson’s disease is tremors, mostly of the arms, which proves to be the most bothersome when performing daily tasks. (National Tremor Foundation, 2020) However, for this only the arms need to be stabilized, so we realized an exoskeleton was not necessary for our demographic. Through further literature study on Parkinson’s disease, it was discovered that diseases with tremors as a symptom are very difficult to distinguish from each other. (Thenganatt & Louis, 2012) To diagnose such a patient correctly takes multiple trips to the hospital, MRI scans and other tests. (Nederlandse Huisartsen Genootschap, 2020) Tremor diseases are found to be distinguishable from each other by the amplitude and frequency, and this can be used to diagnose these diseases correctly. This diagnosis can be made faster and more efficient by our band.

Tremor related diseases

Essential tremor (ET)

ET is a progressive neurological disorder, which causes an involuntary rhythmic pure action tremor, and as such no tremors are experienced while in rest. ET can affect the whole body but it occurs most often in the hands. Due to the lack of medical tests for this disease the diagnosis is at first based on the symptoms. When one has the symptoms of ET then the medical history and family history of the patient is reviewed.

Essential tremor signs and symptoms: • Begin gradually, usually more prominently on one side of the body • Worsen with movement • Usually occur in the hands first, affecting one hand or both hands • Can include a "yes-yes" or "no-no" motion of the head • May be aggravated by emotional stress, fatigue, caffeine or temperature extremes

A patient with ET can be prescribed of multiple types of medication. Firstly Betablockers, these normally are used for treating high blood pressure but also tend to reduce the tremors of patients. Secondly, anti-seizure medication, these often are a replacement for people who don’t respond to betablockers. Lastly, tranquilizers. These are anti-anxiety medications for patients whose ET is affected by their emotional state. These are addictive.

Parkinson’s disease

Parkinson’s disease (PD) is a neurodegenerative disorder that is the second most prevalent in America today, only surpassed by Alzheimer disease. (Marshall & Hale, 2020) 500.000 people have been diagnosed with PD in the United States, but it is believed that this number would be nearing a million if we allowed for misdiagnosed on undiagnosed cases. It is considered a disease that comes with old age. Costs for treatment are high, around $14 billion, and there is no cure as of now.

PD is caused by a malfunction in the neurons in the part of the brain that produces dopamine. Because of this, it becomes harder to control movement. The cause for this degeneration is still unknown. The greatest risks for PD are old age, genetics or prolonged exposure to toxins such as pesticides. PD can come with both motor and nonmotor symptoms, however motor symptoms are most common. These symptoms can affect one side of the body and then later also affect the other side. Tremors most often occur at rest and subside when the patient performs purposeful movements. They worsen because of stress or anxiety. It can also cause Bradykinesia; slowed movements, which can cause feelings of tiredness and weakness. This causes a shuffling way of walking and falling since they cannot adjust their footing quickly enough. Other motor symptoms include: freezing, sudden stopping, slurred speech and stammering.

The most commonly prescribed medication for PD is Levodopa. Levodopa is changed in the brain into dopamine. As PD affects the dopamine production it is the best medication to help control the symptoms slow movements and stiff body parts. Levodopa is often taken along with Carbidopa as Carbidopa increases the effectiveness of Levodopa. This results in smaller doses of Levodopa which reduces the negative side effects. Other types of medication are dopamine agonists. These mimic the effects of dopamine however, they aren’t as effective as dopamine. Furthermore, anticholinergics have often been used in the past. These block involuntary movements to some degree however, it is not often used anymore due to its sideeffects. Amantadine is also used for PD. This increased the availability of dopamine. Lastly, both MAO B inhibitors and COMT inhibitors block the enzyme which is responsible for the breaking down of dopamine in the brain.

Essential tremor vs Parkinson’s disease

ET is occasionally confused with Parkinson’s disease however, there are some key differences. ET is only involved with tremors, there are no other health issues whereas PD may shorten a patient’s lifespan as it causes issues with the brain. Also the tremor affected parts of the body differ. ET involves the hand, head and the voice, while PD cannot be involved with the voice but can be involved with other body parts. Furthermore, ET is a pure action tremor whereas PD is more often a (pure) resting tremor. Lastly, there are difference with the timing of the tremors. ET tremors tend to be of a lower magnitude and with a higher frequency than PD tremors are

Dystonia

The cause of most cases of Dystonia is not currently known. However, in some cases it may be acquired due to brain damage or by genetics. Dystonia can occur at any age but it typically starts at an early age. It is characterized by involunatary muscle contractions causing slow repetitive movements and tremors. Dystonia may affect all parts of the body There are currently no treatments that can prevent dystonia or slow its progress. However, there are treatments that can lessen the symptoms. The most effective treatment is botulinum toxin. These injections are put in the affected muscles to prevent muscle contractions and also decreases muscle spasms. One injection can last for multiple months. Other drugs that are used as medication are anticholerinic agents. These block involuntary movements, however due to sideeffects aren’t used as often. Another type of drugs are GABAergic agents. These drugs regulate the GABA neurotransmitter. Lastly, Dopaminergic agents may be used. These act on the dopamine system which helps the control of muscle movement.

Cerebrellar tremor

This type of tremor is caused by damage to the cerebellum and its pathways, which may be the result of a stroke, a tumor, alcoholism, or a disease. It is characterized by slow tremors with a high amplitude. The tremors always occur in the extremities such as the hands or legs. Cerebellar tremor are currently not effectively treated with the use of medications

Psychogenic tremor

These tremors are caused by some sort of psychiatric disorder such as PTSD. Its tremors can onset in all types of tremors. But are characterized by a few things. Its onset is always very sudden and may affect any part of the body. It is also affected by stress levels.

(Enhanced) Physiologic tremor

Physiologic tremor is not related to a disease but rather a human phenomenon. Any human has a small tremor in their hands and fingers. This tremor can be temporarily enhanced however due to drugs, drugs withdrawal and some medical conditions

Design

Band

If a patient experiences tremor symptoms, they pay a visit to the family doctor. Their doctor can then precribe them to wear this band according to the instruction manual. This band then collects data about the amplitude and frequency of the tremors of the patient.......

In order for the sleeve to be easily put on by tremor patients, the sleeve needs to have as little fastenings, zippers or buttons as possible. (Parkinson's News today, 2020) Patients can use force, however they just cannot complete actions that require detailed movement. Preferred is loose fitting clothing for easy removal. However, our band needs to stay in place, so making the band very loose would cause a hazard in case the band falls off of their arm. An elastic band that is not uncomfortably tight would be the best fit, since this band will stay in place, while the patients are able to put on or remove the band themselves without help.

Instruction manual

Testing should be for around one minute at a time to gather enough data and can be repeated if more data is desired. (Gallego, Rocon, Roa, Moreno, & Pons, 2010)

Model

This model can distinguish between deliberate movements and tremors in order to ensure a correct diagnosis, only based on the actual tremors of the patient. Hier moet nog een beetje uitleg over hoe het model kan zien wat bewuste bewegingen zijn en wat tremors zijn. Dit stond als het goed is in de bron van Jan over het model, dus misschien kan hij dit nog even aanvullen met een (paar) zinnen.

App

Data of the sleeve can be sent to an app on the phone of the doctor using an HC06 module. (Electronoobs, 2020) This allows for the sending of data via a Bluetooth connection between the HC06 module and the phone. The app shows a graph of the data, normalized using a Fourier transform (Ik weet niet of ik dit zo goed zeg, normaliseert een Fourier transform, of is het meer een filter ofzo?), from which the doctor can clearly read out the amplitude and frequency of the tremors of the patients.

By using this app, the doctor can examine the data on his own time and call the patient back later in the day with the results. This saves a lot of back and forth to the hospital for the patient to be examined by a neurologist or other specialists. Misschien kunnen deze laatste twee zinnen beter bij het stukje over hoe een neuroloog nu een diagnose stelt voor een tremorziekte, om te zeggen dat onze manier dus veel sneller en efficienter is etc.

Medical

It is challenging to distinguish between Parkinson’s disease and other diseases with tremor symptoms like essential tremor, both in the beginning and progressing stages of the diseases. (Thenganatt & Louis, 2012) Both essential tremor and Parkinson’s disease show tremor types like rest, postural, kinetic an intention tremors. Both diseases could even coexist in the same patient. Now, the diagnosis is determined by looking at things like tremor frequency and amplitude and associated neurological findings. Laboratory testing may also aid in differentiating these two diseases. Tests like this include: “accelerometry and surface electromyography, spiral analysis, dopamine transporter imaging, olfactory testing and, eventually, postmortem histopathology. These tests have limitations and their diagnostic utility requires additional study.” (Thenganatt & Louis, 2012) This difficulty with diagnosis shows the practicality of a model that could acquire data from which the doctor could determined the correct diagnosis, thus bypassing extensive clinical testing.

Frustration

PD patients get frustrated when they are dependent on partners or carers for performing daily tasks. (National Tremor Foundation, 2020) They often lack necessary confidence when these helpers are not there. Simple household tasks like cleaning and cooking are really difficult or even impossible. Carrying lightly weighted objects makes these tremors even worse. (Robakis & Louis, 2014) An early and correct diagnosis is thus very important to improve the quality of life of patients with tremor symptoms.

Ethical considerations

It is of utmost importance to pay attention to the balance between benefiting the patients’ quality of life, and avoiding damage, risk or injury. (Bulboacă, Bolboacă, & Bulboacă, 2017)

Most concerns around electronic health records (EHRs) like the data the model will calculate and store are around privacy, confidentiality and the jeopardization of autonomy. (Ozair, Jamshed, Sharma, & Aggarwal, 2015) EHRs are massively being implemented because of their several advantages over paper records, since they increase healthcare access, decrease costs and improve care quality. Autonomy can be taken away from patients if their data is shared without their knowledge. Because of this, a patient might choose to withhold important information in fear of their data being leaked. This can cause suboptimal treatment plans with undesired outcomes. Following privacy and confidentiality guidelines, information about a patient can only be shared with third parties with the patients’ consent. Clinical data is confidential and must always be safeguarded. When this patient cannot give informed consent because of mental capacity or old age, this decision falls upon their guardian or legal representative. Data leaks violate a patients’ privacy and thus damage trust in the health care system as a whole. The fact that the privacy and autonomy of patients can be compromised when collecting data from them in a clinical setting is an ethical question that needs to be at the forefront of the development of this sleeve.

Moreover, when can a doctor decide if this sleeve should be worn by a patient? Under which conditions should the sleeve be applied? What should a patient expect from the sleeve? These conditions should be determined before usage to avoid conflict. Little guidance exists in health care, which results in competing pressures and affects the way that the sleeve is put into practice. (Foye et al, 2002)

Beyond conflicts also the clinical reasoning process is being affected by reimbursement or money issues and this raises significant concerns about the way in which we assess the quality of the provided services of the sleeve. If the sleeve is not in the family medicine budget, it will not see the light of day. If the patient needs to buy it to own it and be able to use it, they will only do so if the symptoms become severe. By this time, treatment could have been started way earlier, combating these symptoms.

Another closely related issue that arises is that the patient will get less attention from health care professionals compared to now. This can feel less personal, so patients might not feel like they get the care they deserve, even though this model makes the diagnosis more accurate and faster.

This article talks about the implications with on the one side the increasing acceptance of disability, and on the other side the rapid scientific developments in the medical field. If you could just function as a non-disabled person again with the help of an exoskeleton, would you still be able to choose to not use this medical advancement? Would you still have a free choice in this, or are you frowned upon when you do not want to “fix” your disability?

This research paper evaluates some ethical questions about the domestic use of a robotic exoskeleton (ReWalk Robotics) for gait assistance in patients with a spinal cord injury. “This device is presently FDA and EC market approved and it is now available”. It talks about ethical concerns like financial coverage because of personal resources, but learning to walk again is of high priority for patients

One yet existing exoskeleton is the RUPERT (Robotic upper extremity repetitive trainer). This device has 5 actuated degrees of freedom which are driven by compliant and safe pneumatic (operated by air or gas under pressure.) muscle actuators. This helps with shoulder elevation, elbow extension, forearm supination (turning your arm outwards) and humeral external rotation. There is no gravity compensation for this exoskelet. The system is lightweight and uses a PID-based controller combined with an ILC (iterative learning controller) controller. (Balasubramanian, 2008) https://ieeexplore.ieee.org/document/4625154

The state of the art of currently available lower limb assistive exoskeletons is presented in this paper. The functional abilities and the mechanism designs are described. In conclusion, there is still a lot to improve on assistive exoskeletons like choosing the proper and effective tools methods, developing user friendly interfaces and making the devices more affordable. (Kapsalyamov, 2019) https://ieeexplore.ieee.org/abstract/document/8759880

To operate a robotic exoskeleton a control system is needed to monitor an output of electrical activity sensors which are disposed on the human operator. The control system reacts automatically an the step the human makes, choosing from a plurality of different modes. Eventually the operating mode selected will determine the response the system will have to make. (Wilkinson, 2014) https://patents.google.com/patent/US9339396B2/en

The lower-limb exoskeleton is designed to provide weight-bearing assistance for strength and endurance augmentation. It has 10 degrees of freedom. A trajectory learning scheme based on RL (reinforcement learning) and DMP (dynamic movement principles) is present to give assistance to human walking. A two-level plan is presented, the first one concerns the ZMP (zero-moment-point) within the ankle joint for the supported leg. For this purpose the inverted pendulum approximation is utilized, this is done with the so called locomotion parameters. The second level models the joint trajectories learned by the DMP. The RL is now adopted to learn these trajectories so that it can eliminate all the uncertainties in the joint space. The experiments show that it is an effective method for minimizing disturbances and uncertainties. (Yuan, 2019) https://dr.ntu.edu.sg/handle/10356/88973

The robots used for physical rehabilitation allow the patient a compliance and a quantitative, more accurate monitoring of the performance of the patient. However when the patients go back home, it is logistically not possible to keep this same kind of support. Recent research in soft materials for designing robotic devices can make this possible. These are made of fabric and elastomers, is a promising way of delivering power and being ergonomic. Features like assisting the elbow joint and compensating the gravitational forces with a controller are developed and evaluated. It is tested on both the kinetics and kinematics of healthy people.

The IHMC exoskeleton is a suit that can be used to gain more strength. The first prototypes were targeted for walking assistance for persons with lower paralysis. The goal is to successfully enable a person to walk a straight line of a distance of 15 feet without human assistance. https://ieeexplore.ieee.org/abstract/document/5152394

In this paper the development of a lower limb exoskeleton is described. These twin legs are powered by pneumatic muscle actuators. These are low mass high power to weight and volume actuation system. These “muscles” being pneumatic means that a more natural muscle like feeling is achieved. This exoskeleton is mostly used for rehabilitation. https://ieeexplore.ieee.org/abstract/document/1639137

CRUX: compliant robotic upper-extermity exosuit. This exosuit is a lightweight (1.3 kg), has flexible multi-joitn design for portable augmentation. The CRUX also maintains the ability to freely move why wearing it. Mostly used for physical therapy and in extreme environments. It is mostly used for people suffering from stroke. It can help these people with the rehabilitation. Most of these rehabiliations now a days succeed. CRUX can provide a solution for this. https://ieeexplore.ieee.org/abstract/document/8009482

In this article a exosuit is talked about that can help people with hip problems. It uses a backpack frame to connect to the torso. Beneftis of using this method is that exosuits eliminate the problem regarding the alignment of a rigid frame to the biological joints, furthermore the inertia of the joints can be extremely low, meaning less muscle power has to be used. A spooled-webbing of actuators is attached onto the back of the user. These actuators can assist the user. Due to this mechanics more torque is achieved which means that for the same movement 30% less power is needed. https://www.sciencedirect.com/science/article/abs/pii/S0921889014002103

In this article the biomechanical and physiological effects of a multi-joint soft exosuit are assessed. This exosuit can apply a assisting torque to the hip and ankle joints during walking. This study has looked at the effects of the exosuit on the characteristics of the movement of humans. It appeared that the suit is able to support most of the power that is needed to walk. However there is a decline in kinematic performance with this suit on. This is technical limitation. https://jneuroengrehab.biomedcentral.com/articles/10.1186/s12984-016-0150-9
