Trial Summary

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications.

What data supports the effectiveness of the treatment Vibrotactile Stimulation (VTS) for chronic cough?

Research on similar treatments, like neck muscle vibration, shows it can have lasting beneficial effects in other conditions, such as spatial neglect, suggesting potential for positive outcomes in chronic cough. ^{1 2 3 4 5}

Is neck vibration therapy generally safe for humans?

Research on vibrotactile stimulation, which is similar to neck vibration therapy, shows it is generally safe for humans. Studies have used it for various conditions, like sleep apnea and balance disorders, without major safety concerns. ^{6 7 8 9 10}

How does neck vibration therapy for chronic cough differ from other treatments?

Neck vibration therapy for chronic cough is unique because it uses vibrotactile stimulation (VTS), which involves applying vibrations to the neck area. This method is non-invasive and may work by stimulating sensory receptors, potentially altering nerve signals related to cough reflexes, unlike traditional treatments that often involve medication. ^{2 4 6 11 12}

What is the purpose of this trial?

Researchers will test the effect of non-invasive vibrotactile stimulation of the larynx on symptom severity of unexplained chronic cough.

Findings from Research

Vibroacoustic therapy (VAT) has been explored in 20 studies focusing on pain management, primarily for chronic pain, but the research is limited and lacks consistency in protocols, making it difficult to draw definitive conclusions about its efficacy.

Most studies used a frequency of 40 Hz for VAT sessions lasting between 20 to 45 minutes, with more frequent treatments for acute pain compared to chronic pain, highlighting the need for standardized measurements and randomized controlled trials to better understand VAT's effectiveness.

In a study involving high-frequency (100Hz) transcutaneous electrical nerve stimulation (TENS) applied for 13 minutes, TENS at a proximal site significantly increased vibrotactile thresholds for both 20Hz and 150Hz stimuli.

The elevation in vibrotactile thresholds is likely caused by peripheral electrogenic blockade, indicating that TENS can interfere with the normal function of vibration receptors.

In a study involving 20 severely disabled patients, vibration therapy (VT) significantly reduced state anxiety levels and cortisol, a stress hormone, indicating its potential as an anti-stress intervention.

Despite no changes in socio-psychological variables, the results suggest that short exposure to low-frequency vibration is a safe and effective method to improve hormone responses in this population.

The study found that the temporary threshold shift of vibratory sensation (TTS(v)) in the fingertip increases significantly with longer exposure to hand-arm vibration, indicating a clear relationship between exposure duration and sensory threshold changes.

The recovery of TTS(v) after vibration exposure follows an exponential pattern, suggesting that the time taken to return to baseline sensitivity may require improved measurement methods for more accurate assessment.

In a study involving 20 patients with left-sided neglect, combining neck muscle vibration with visual exploration training led to significant and lasting improvements in neglect symptoms, particularly in visual perception and daily activities, observed two months post-treatment.

In contrast, visual exploration training alone provided only minor benefits, highlighting the importance of neck muscle vibration as an effective rehabilitation technique for spatial neglect.

Vibrotactile positional therapy (PT) significantly reduced the Apnoea Hypopnoea Index (AHI) by an average of 9.19 events/hour and decreased the percentage of time spent in the supine position (%Tsupine) by 32.79% in patients with positional obstructive sleep apnoea (POSA), based on a systematic review of 18 studies involving 1119 initial studies.

While vibrotactile PT was effective in reducing AHI and %Tsupine, its impact on secondary outcomes like daytime sleepiness and quality of life was minimal, indicating a need for further research to explore these aspects more thoroughly.

In a pilot study with 8 participants suffering from unilateral vestibular disorders, those who received vibrotactile sensory augmentation during balance training showed significantly greater improvements in balance confidence and postural stability compared to those who did not receive this sensory aid.

The benefits of incorporating vibrotactile sensory augmentation were observed to last up to six months after the training, suggesting it may enhance vestibular rehabilitation outcomes.

A study involving 10 male subjects found that simultaneous exposure to whole-body vibration (WBV) and hand-arm vibration (HAV) significantly increased the vibrotactile perception threshold (VPT), indicating a greater impact on sensory perception compared to exposure to either type of vibration alone.

The results suggest that combined vibration exposure can lead to more pronounced changes in sensory perception, which could have implications for understanding the effects of vibration in occupational settings.

This pilot study investigates how two different vibrotactile feedback devices can help elderly individuals with body orientation and sensory information during walking tasks.

The results suggest that sensory substitution devices using vibrotactile feedback may improve locomotion in older adults, highlighting their potential as assistive technologies for enhancing mobility and safety.

Vibrotactile stimulation (VS) on the forearm was found to elicit higher subjective responses from participants when applied to the lateral side compared to the medial side, across all groups studied (young adults, elderly, and amputees).

Some participants reported feelings of displeasure in response to VS, indicating that emotional responses to vibration can vary by factors such as age, sex, and amputation status.

High frequency vibration (110 Hz) significantly increases the muscular pain threshold in healthy individuals when applied to the skin overlying the quadriceps tendon, indicating a potential method for pain modulation.

This pain threshold elevation is likely due to the activation of rapidly adapting receptors and pacinian corpuscles, which may inhibit pain signals at the spinal level, while low frequency vibration (30 Hz) does not have a consistent effect.
