Brief summary

The program, called TMC-CP01, will use a combination of virtual reality, biofeedback, and psychological exercises to manage pain associated with Chronic Low Back Pain. Chronic pain affects an estimated 100 million Americans, around one-third of the U.S. population. One of the most prevalent conditions under chronic pain is Chronic Low Back Pain (CLBP). About 27% of chronic pain patients experience CLBP. It is the leading cause of disability in the world and 31 million Americans suffer from CLBP. The most common analgesic tool for pain patients, especially for LBP patients, is opioids. However, opioid users are subject to drug tolerance and physical dependence, which decreases efficacy and increases risk of complication. Long-term users often require doses up to ten times their original dose to achieve equivalent analgesia and, after months of exposure, patients' risk of addiction increases. This project aims to introduce a digital intervention to standard CLBP management with a virtual reality-enabled pain management system that will improve pain management and decrease daily dosages of opioids.

Detailed description

TMC-CP01 is a treatment based on the VANISH (Virtual Autonomic Neuromodulation Induced Systemic Healing) system and method, which combines existing technologies and therapies into Virtual Reality (VR) to help people learn to auto-regulate the way their body feels. TMC-CP01 is designed specifically for pain management and is tailored for low back pain. The treatment utilizes virtual reality and biofeedback to train patients to auto-regulate themselves and improve their pain over time. By providing patients an accessible and effective alternative pain management tool, patients can avoid opioid use, dependency, and resulting complications due to opioids. Change in daily opioid dose, expressed in morphine equivalents, is the primary outcome. TMC-CP01 uses virtual reality as a platform to enable and optimize biofeedback training and psychological exercises. Virtual Reality, alone is a proven method for pain management both through distraction and through active pain control mechanisms. Due to its stimulating nature, VR has the power to claim the majority of a user's attention and distract them from other stimuli such as pain. Because it is so visually engaging, VR is a powerful tool for visualization, which can be used to optimize and enhance visualization of biofeedback. VR can also affect users' emotions and perception by providing a sense of presence and psychological engagement. With recent developments in portable head mounted display (HMD) technology, VR has become accessible to people on a much broader and more affordable scale and it represents an ideal platform to develop a non-invasive pain management tool for chronic pain. Biofeedback is at the heart of TMC-CP01 and is the main mechanism by which patients learn to control their physiology. By allowing patients to visualize their physiological processes, patients gain a greater mind-body awareness and can learn to auto-regulate physiological functions that previously seemed out of their control.

MeasureTime frameDescription
Flowly (TMC-CP01) Virtual Reality Intervention Feasibility Via Change From Baseline in Heart Rate Variability (HRV) at 8 Weeks8 WeeksHRV will be modulated by conforming respiration and heart rate to optimal breathing patterns. The games are designed to guide subjects' physiology to a more optimal state for pain reduction using biofeedback. Resonant breathing is breathing that activates the coordinated function of oscillating body systems. This breathing increases your Heart Rate Variability. Greater Heart Rate Variability (a higher HRV score) at rest indicates better outcomes. Outcomes will be measured over the span of the study and compared between the two groups.
Change From Baseline in Opioid Cravings Using the Craving Index at 8 Weeksweekly, up to 8 weeksThe Craving Index questionnaire on the Flowly app assesses opioid cravings using 6 qualitatively scaled questions, ranging from 'none' (minimum score: 0) to 'the greatest possibility' (maximum score: 5 per question, total score: 30). Lower scores indicate less frequent opioid cravings, suggesting better outcomes. Measurements were assessed weekly, and the analysis focused on comparing scores between baseline and 8 weeks to evaluate changes in cravings between the two groups.
Change From Baseline in Physical Function Using PROMIS Physical Function Short Form T-score at 8 WeeksAssessed weekly, change from baseline and Week 8 reportedThe investigators used the PROMIS Physical Function Short Form T-score to assess key patient-centered outcomes related to physical function. This assessment includes 4 physical function-related questions, each scored on a 5-point Likert scale (1 = unable to do, 5 = without any difficulty). The raw total score ranges from a minimum of 4 to a maximum of 20. Responses were converted to T-scores, where the mean in the general population is 50 with a standard deviation of 10. Higher T-scores indicate better physical function, while lower T-scores suggest worse physical function. Clinically relevant thresholds may indicate that lower scores are associated with greater physical disability. Measurements were conducted at baseline and Week 8, with the analysis focused on comparing changes in physical function between the two groups.
Change From Baseline in Fatigue Using PROMIS Fatigue Short Form T-score at 8 WeeksBaseline and Week 8The investigators used the PROMIS Fatigue Short Form T-score to assess key patient-centered outcomes related to fatigue. This assessment includes 4 fatigue-related questions, each scored on a 5-point Likert scale (1 = not at all, 5 = very much). The raw total score ranges from a minimum of 4 to a maximum of 20. Responses were converted to T-scores, where the mean in the general population is 50 with a standard deviation of 10. Higher T-scores indicate greater fatigue, while lower T-scores suggest less fatigue, which reflects better outcomes. Clinically relevant thresholds suggest that elevated T-scores may indicate increased fatigue severity. Measurements were conducted at baseline and Week 8, with the analysis focused on comparing changes in fatigue levels between the two groups.
Change From Baseline in Pain Interference Using the PROMIS Pain Interference Short Form at 8 WeeksAssessed weekly, change from baseline and Week 8 reportedThe investigators used the PROMIS Pain Interference Short Form to assess how pain impacts daily activities. This measure includes 5 pain-related questions, each scored on a 5-point Likert scale (1 = not at all, 5 = very much). The raw total score (range: 5 to 25) was converted to a standardized T-score (mean = 50, SD = 10). Higher T-scores indicate greater pain interference, while lower T-scores suggest less interference (better outcomes). A T-score of 60+ may indicate clinically significant pain interference, while 40 or lower suggests minimal interference. Measurements were conducted over the study, with scores compared between baseline and 8 weeks to assess changes in pain interference.
Change From Baseline in Pain Intensity Using the PROMIS Pain Intensity Item at 8 WeeksAssessed weekly, change from baseline and Week 8 reportedThe investigators used the PROMIS Pain Intensity Item to assess patients' self-reported pain levels. This measure consists of one question, scored on an 11-point Likert scale (0 = no pain, 10 = worst imaginable pain). The raw score was converted to a standardized T-score (mean = 50, SD = 10). Higher T-scores indicate greater pain intensity, while lower T-scores suggest less pain (better outcomes). A T-score of 60+ may indicate clinically significant pain, while 40 or lower suggests mild or minimal pain. Measurements were conducted throughout the study, with scores compared between baseline and 8 weeks to assess changes in pain intensity.
Change From Baseline in Sleep Disturbance Using the PROMIS Sleep Disturbance Short Form at 8 WeeksAssessed weekly, change from baseline and Week 8 reportedThe investigators used the PROMIS Sleep Disturbance Short Form to assess patient-reported sleep difficulties. This measure includes 4 items, each rated on a 5-point Likert scale (1 = not at all, 5 = very much). The raw score (range: 4 to 20) was converted to a T-score (mean = 50, SD = 10). Higher T-scores indicate greater sleep disturbance (worse outcomes), while lower T-scores suggest better sleep quality. A T-score of 60+ may indicate clinically significant sleep disturbance, while 40 or lower suggests minimal issues. Measurements were conducted throughout the study, with scores compared between baseline and 8 weeks to assess changes in sleep disturbance.
Change From Baseline in Ability to Participate in Social Roles and Activities Using the PROMIS Short Form at 8 WeeksAssessed weekly, change from baseline and Week 8 reportedThe investigators used the PROMIS Ability to Participate in Social Roles and Activities Short Form to assess social participation.

The Positive Outlook Short Form measures subjects' perceptions and feelings about the future using 6 items, each rated on a 5-point Likert scale (1 = not at all, 5 = very much). The raw score (range: 6 to 30) is converted to a T-score (mean = 50, SD = 10) for standardized interpretation. Higher T-scores indicate greater optimism and a more positive outlook, suggesting better psychological well-being. Lower T-scores reflect greater pessimism or concerns about the future. A T-score above 60 may indicate high optimism, while a T-score below 40 suggests low optimism or increased negative expectations.

Flowly (TMC-CP01) Virtual Reality Intervention Feasibility Via Change From Baseline in Heart Rate Variability (HRV) at 8 Weeks

HRV will be modulated by conforming respiration and heart rate to optimal breathing patterns. The games are designed to guide subjects' physiology to a more optimal state for pain reduction using biofeedback. Resonant breathing is breathing that activates the coordinated function of oscillating body systems. This breathing increases your Heart Rate Variability. Greater Heart Rate Variability (a higher HRV score) at rest indicates better outcomes. Outcomes will be measured over the span of the study and compared between the two groups.

Time frame: 8 Weeks

Population: HRV data were not collected due to a malfunction in the Flowly app, which was in beta testing during the study. The app was intended to collect HRV via a paired biometric sensor, but it failed to reliably communicate with the device. As a result, HRV measurements were not transmitted or stored, and no usable data were available for analysis.
