Deep brain stimulation (DBS) is a surgery to implant a device that sends electrical signals to brain areas responsible for body movement. Electrodes are placed deep in the brain and are connected to a stimulator device. Similar to a heart pacemaker, a neurostimulator uses electric pulses to regulate brain activity. DBS can help reduce the symptoms of tremor, slowness, stiffness, and walking problems caused by Parkinson's disease, dystonia, or essential tremor. Successful DBS allows people to potentially reduce their medications and improve their quality of life.
In deep brain stimulation, electrodes are placed in a specific area of the brain depending on the symptoms being treated. The electrodes are placed on both the left and right sides of the brain through small holes made at the top of the skull. The electrodes are connected by long wires that travel under the skin and down the neck to a battery-powered stimulator under the skin of the chest (Fig. 1). When turned on, the stimulator sends electrical pulses to regulate the faulty nerve signals causing tremors, rigidity, and other symptoms.
For Parkinson's disease, DBS of the subthalamic nucleus improves the symptoms of slowness, tremor, and rigidity in about 70% of patients . Most people are able to reduce their medications and lessen their side effects, including dyskinesias. It has also been shown to be superior in long term management of symptoms than medications .
DBS of the globus pallidus (GPi) is most useful in treatment of dyskinesias (involuntary wiggly movements), dystonias, as well as other tremors. For dystonia, DBS of the GPi may be the only effective treatment for debilitating symptoms. Though recent studies show little difference between GPi-DBS and STN-DBS.
Once the DBS has been programmed, you are sent home with instructions for adjusting your own stimulation. The handheld controller allows you turn the stimulator on and off, select programs, and adjust the strength of the stimulation. Most patients keep their DBS system turned on 24 hours day and night. Some patients with essential tremor can use it during the day and turn off the system before bedtime. Your doctor may alter the settings on follow-up visits if necessary.

Lifestyle interventions focusing on the use of weighted utensils can reduce the amplitude of tremor and alleviate the challenges patients face in their activities of daily living (ADLs) [15,16]. With additional weights, these utensils (e.g., spoon) can assist patients to eat and drink. In 2017, the National Institute for Health and Care Excellence (NICE) produced guidelines for the management of PD in adults . Patients in the early stages of PD may benefit from physio- and occupational therapy if they experience motor symptoms or have difficulties with ADLs . However, lifestyle and the nonpharmacological management of ET were not discussed in the guidelines produced by the American Academy of Neurology (AAN) and the IPMDS [17,18,19]. A systematic review of 19 studies found that physical therapy, limb cooling, vibration therapy, use of limb weights, bright light therapy, and transcranial magnetic stimulation were all examples of investigated treatments of tremor . However, these studies mainly included convenience samples, and the long-term effectiveness of these interventions was not assessed .
Pharmacotherapy for the treatment of ET is suboptimal and only treats the symptoms. Many patients do not respond to the existing medications indicated for ET and do not experience a significant improvement in their daily living. Currently, propranolol and primidone are the two first-line therapies [15,16,17,18,19,21]. Across randomized controlled trials (RCTs), propranolol and primidone monotherapy produce a mean reduction in the tremor amplitude of 54.1% and 59.9%, respectively, as measured by accelerometry . Nonetheless, 56.3% of patients eventually discontinued the use of either medications . Topiramate is also recommended as a first-line therapy by the guidelines of the Italian Movement Disorders Association (IMDA)  and is considered clinically useful at higher doses by the IPMDS task force . However, it is recommended by the AAN guidelines as a second-line therapy [17,18]. Second-line medications have been reported to be less efficacious in reducing the amplitude of tremors. These include alprazolam, atenolol, gabapentin, and sotalol, as well as the aforementioned topiramate [17,18]. In contrast, there is no consensus in the management of PD tremors. The current NICE guidelines recommend levodopa as the first-line therapy for management of all motor symptoms in patients in the early stages of PD .
Deep brain stimulation (DBS), whose efficacy has been demonstrated through closed loop approaches [25,26] and interleaving stimulation , is the most common surgical treatment to date, providing durable tremor control, especially for patients with medically refractory ET or advanced PD. The effectiveness of DBS in ET and PD tremor is thought to be due to the direct electrical stimulation to the ventral intermediate nucleus (VIM) possibly disrupting the synchronous firing of thalamic neurons [28,29]. In addition to the VIM, the subthalamic nucleus, internal globus pallidus, and pedunculopontine nucleus are also effective targets for DBS in patients with PD tremors . The use of DBS was approved by the Food and Drug Administration (FDA) for ET in 1997, for advanced PD in 2002, and for mid-stage PD in 2016. As of late, radiofrequency thalamotomy has become less favored. An RCT comparing DBS with thalamotomy in 68 patients with tremor due to ET, PD, or multiple sclerosis found that DBS results in fewer adverse effects (p = 0.024) and a greater increase in the Frenchay Activities Index score, which assess 15 ADLs. This suggests a greater improvement in the functional status when compared to thalamotomy . Although surgical treatments for tremors, including DBS, stereotactic radiosurgery (SRS), and magnetic resonance-guided focused ultrasound (MRgFUS), are more efficacious than pharmacotherapy , the utilization of these procedures remains low. Limiting factors may include high surgical costs [33,34], access to care [35,36], and patient preference . Other perceived barriers to DBS include practitioner preference [34,37], high resource and labor intensity [34,38], and perceptions of serious surgical risk [34,38,39].
Thus, a growing unmet need for safe and effective tremor control and suppression sets the stage for a range of therapies to bridge this gap between lifestyle modifications, pharmacotherapy, and surgical treatment. Using a variety of noninvasive suppression mechanisms, medical devices fit within this gap to provide effective tremor suppression at a lower risk than surgery. The increasing interest in this area has led to the birth of a new classification of external upper limb tremor stimulators. In 2018, the de novo classification request of Cala ONE (Cala Health, Burlingame, CA, USA) received FDA approval .
In 2018, Cala ONE was the first wearable transcutaneous electrical nerve stimulator to be approved by the FDA . The newer version of this device, Cala Trio (Cala Health, USA; previously known as Cala TWO), is currently FDA-registered. The PROspective study for SymPtomatic relief of Essential tremor with Cala Therapy (PROSPECT) pivotal trial for Cala Trio was completed in 2019 , but it is still waiting for approval by the FDA. Clinically, Cala Trio is designed to replace Cala ONE for use in the transient, symptomatic relief of hand tremors in adults with ET. This device can be worn for therapy on the left or right wrist.
MOTIMOVE functional electrical stimulation system. This device (3F-Fit Fabricando Faber, Serbia) comprises a multichannel stimulator that attaches to several electrodes placed on the flexor and extensor muscles of the forearm, enabling muscle activation.
The MOTIMOVE system consists of a multichannel stimulator that provides support to activate several electrodes, placed on the forearm and upper arm above the flexor and extensor muscle points, that enable the selective muscle activation via distributed, asynchronous electrical stimulation. The inertial sensors within MOTIMOVE deliver real-time estimation of tremulous movements to a host computer, which provides control over the stimulation of muscles. This system delivers out-of-phase stimulation by sending electrical current pulses to the flexor and extensor muscles, triggering the depolarization of motor neurons that counteracts the tremorgenic activity. A pilot study of MOTIMOVE revealed a 67% tremor suppression in six of seven patients with ET or PD . One patient, however, did not respond, suggesting that out-of-phase stimulation may not work for all patients with tremor . Additional clinical studies evaluating the MOTIMOVE system are claimed to be currently in progress in Serbia, France, and Hungary, which will hopefully demonstrate its efficacy in tremor suppression and feasibility. 153554b96e
