About this trial
The purpose of this study it to test the efficacy of a wearable device to improve symptom management and maximize qualify of life in systemic Sclerosis (SSc) patients in a randomized trial. Specifically, we will evaluate if the Apollo Neuro device may improve the two specific symptoms highest ranked by patients as affecting qualify of life (fatigue, Raynaud phenomenon) as co-primary outcomes.

Treatments tested in this trial
Apollo Neuro Device
DeviceThe Apollo Neuro wearable device is an Apple Watch-sized wearable device that delivers vibration at set frequencies , termed transcutaneous vibratory stimulation, or TVS. These low volume sound waves feel like a soothing touch to the skin (TVS) and activate touch receptors. Apollo is controlled via smartphone and worn on the wrist or ankle. The Apollo is fitted with an adjustable band, made of a durable neoprene material with polyester overlays. Participants are asked to wear it daily for a minimum time period for 6 weeks. Users can choose from different modes of vibration, with some being energizing, others relaxing.
Sham device
DeviceThe Apollo Neuro is an Apple Watch-sized wearable device that delivers vibration, termed transcutaneous vibratory stimulation, or TVS. The sham device is identical in appearance to the active intervention, but provides a lower frequency vibration that has no known therapeutic benefit.
Treatment groups
Trial outcomes
Primary outcomes
Change in fatigue
The PROMIS® (Patient-Reported Outcomes Measurement Information System) SF v1.0 Fatigue 13a scale. This is a13-item, patient reported measure of an individual's level of fatigue during their usual daily activities over the past week. The raw score is converted to a T-score for analysis with 50 for the mean and a standard deviation of 10.
Change in average weekly Raynaud attacks
Average number of weekly Raynaud attacks. Over a period of one week, patients will record their Raynaud phenomenon (RP) attack frequency via a smartphone app. The Raynaud app is usable on both Apple iPhones and Android phones.
Secondary outcomes
Change in quality of life
The EuroQol (EQ)-5D-5L will be used. The quality-of-life assessment instrument has 5 dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression plus a patient global assessment visual analog scale (VAS). In the EQ-5D-5L each dimension is ranked on 5 levels of severity. Full health is a score of 1 and values below zero are regarded as a state worse than death.
Change in Raynaud phenomenon symptom severity
The ASRAP (Assessment of Scleroderma-associated RAynaud's Phenomenon) Questionnaire Short form is a 10-item patient self-report questionnaire regarding symptoms over the last week. Raw scores are converted to T-score with a median of 50.
Change in the Raynaud Condition Score
The Raynaud Condition Score is a patient-reported outcome of a single question regarding Raynaud severity. It is a visual analog scale with a results range of 0-100. A score of 0 is no symptoms, and 100 is severe symptoms. It is recommended by OMERACT for assessment of Raynaud phenomenon.
Change Sleep
PROMIS® Sleep disturbance short form 4a will be used. This 4-item questionnaire uses a 5-point Likert scale for responses, inquiring about symptoms over the last week. Raw scores are converted to T-scores, with a mean of 50 and SD of 10.
