Abstract
Background
Mind-body treatments have the potential to manage pain, yet their effectiveness when delivered online for the treatment of low back pain (LBP) is unknown. We sought to evaluate whether a virtually delivered mind-body program integrating tai chi, qigong, and meditation (VDTQM) is effective for treating LBP.
Methods
This randomized controlled trial compared VDTQM (n=175) to waitlist control (n=175). Eligible participants were at least 18 years old, had LBP for at least 6 weeks, were not pregnant, had not previously taken tai chi classes, and had not undergone spine surgery within 6 months. The treatment group received a 12-week VDTQM program in live online 60-minute twice-weekly group classes from September 2022 to December 2022. All participants continued their usual activities and care. Primary outcome was pain-related disability assessed by the Oswestry Disability Index (ODI) score. Secondary outcomes included pain intensity, sleep quality, and quality of life (QOL). Intent-to-treat analyses were conducted.
Results
Of the 350 participants 278 (79%) were female, mean age was 58.8 years (range: 21–92), 244 (69.7%) completed the 8-week survey, 248 (70.9%) the 12-week, and 238 (68%) the 16 -week. No participants withdrew due to adverse treatment effects. Compared with control group, treatment group experienced statistically and clinically significant improvement in ODI score by −4.7 (95% CI: −6.24 to −3.16, p<.01), −6.42 (95% CI: −7.96 to −4.88, p<.01), and −8.14 (95% CI: −9.68 to −6.59, p<.01) points at weeks 8, 12, and 16, respectively. Treatment group also experienced statistically significant improvement at all time points in the other outcomes.
Conclusions
Among adults with LBP, VDTQM treatment resulted in small to moderate improvements in pain-related disability, pain intensity, sleep quality, and QOL. Improvements persisted 1 month after treatment concluded. These findings suggest VDTQM may be a viable treatment option for patients with LBP.

Background
Low back pain (LBP) remains the leading cause of disability worldwide [1], impacting 619 million individuals [2] in 2020 and a projected 843 million [3] in 2050. Safe, effective, and accessible treatment at a low cost is needed. Increasing evidence demonstrates the promise of nonpharmacologic treatments such as those that focus on body movement and/or mental retraining [4] to attenuate pain and improve disability in individuals with LBP [5]. Nonpharmacologic approaches are often recommended as an initial LBP treatment [6].
Social distancing requirements during the COVID-19 pandemic complicated matters for nonpharmacologic therapies. Increased telemedicine availability spurred by the COVID-19 pandemic allowed patients to continue receiving care and provided an opportunity to investigate telerehabilitation effectiveness for patients with LBP. In-person therapies can be difficult for patients to access due to a dearth of available facilities, cost, scheduling, or physical condition [7]. Preliminary research indicates digitally delivered physiotherapy may be effective treatment for improving disability and reducing pain [8]. However, evidence is mixed [9] and further research regarding the effectiveness of virtually delivered therapies is needed.
Qigong is an ancient Chinese healing art for nurturing vital energy. Tai chi, a series of bodily movements incorporating qigong practice, has healing and martial art function with demonstrated benefits to sleep [10], immune function [11], fall prevention [12], cardiac rehabilitation [13,14], and overall well-being [15], as well as increasing the likelihood of return to work [5]. Recently, 2 tai chi studies [16,17] and 1 qigong study [18] demonstrated short-term small to moderate effects on improving LBP and disability.
Qigong practice emphasizes both stillness and movement, 2 essential components for LBP relief and injury prevention according to Chinese healing and martial arts. Stillness meditation (adaptable for standing, sitting, and lying down) is thought to promote calmness, resilience, body awareness, deeper relaxation, and strength. Slow, simple movements are thought to further cultivate relaxation, flexibility, energy flow, and proper body alignment in motion [19]. A curriculum integrating stillness and movement has the potential to serve as a feasible nonpharmacologic treatment option for adults with LBP. To our knowledge, this is the first investigation of a virtually delivered integrated tai chi, qigong, and meditation program (VDTQM) with a balanced focus on stillness and movement.
The principal aim of this study was to assess the effectiveness of a VDTQM program integrating stillness and movement among adults living with LBP. Our hypothesis was that participants engaged in the treatment would experience greater improvement in pain-related disability, pain intensity, sleep quality, and health-related QOL compared to the waitlist control group.
Methods
Study design, settings, and participants
In this prospective randomized controlled trial, adults with LBP were assigned into 1 of 2 groups: a VDTQM (treatment) group and a waitlist control group. Of 417 recruited individuals recruited from July 2022 to September 2022, a total of 350 participants primarily from the New York City Metropolitan Area and Portland, Maine met inclusion criteria and were enrolled and randomized. Participants were recruited through a variety of routes, such as: emails to mailing lists of a podcast of the Comprehensive Spine Care Center at Weill Cornell Medicine for people with LBP; referrals from physicians of primary care, geriatrics, and osteopathic medicine; and an employee wellness program newsletter that went to approximately 80,000 employees at Northwell Health in the New York area.
Participants in the treatment group received free live online sessions for 12 weeks from September 2022 to December 2022. The waitlist control group had the option to participate in the free VDTQM program 1 week after the final study follow-up, from January 2023 to April 2023. Outcome measures were collected electronically from both groups at baseline, 8 weeks, 12 weeks (at the conclusion of the treatment), and 16 weeks (4 weeks after the conclusion of the treatment). The research protocol was approved by the Institutional Review Board of the New York Medical College (IRB approval number: GMB 15574, see protocol in Supplementary 1). Informed consent was obtained from all participants before randomization.
Inclusion and exclusion criteria
Participants were eligible to participate if they were at least 18 years old, had experienced LBP for at least 6 weeks prior to study enrollment, understood written and spoken English, were not pregnant, had not previously taken tai chi classes, and had not undergone spinal surgery within the last 6 months.
Randomization and blinding
After completing the baseline survey, eligible participants were assigned a value between 0 and 1 with a random number generator in Stata [20], then sorted by this random number. The first half of the participants were assigned to the treatment group and the second half to the control group. Due to the nature of this behavioral treatment, it was not possible to blind the participants.
Intervention
The VDTQM program is a treatment developed to reduce LBP and associated disability. The practice follows foundational principles of Chinese medicine for healing and pain relief: cultivating a tranquil mind and relaxed body [19]. The program is based on tai chi and qigong exercises and meditation developed by the first author. Each session lasted approximately 60 minutes, comprising six 10-minute segments: energy cultivation, standing meditation, spinal flexibility, lying down meditation, core strength, and sitting meditation (a link to a typical class is provided in Supplementary 2). Approximately every 4 classes, 1 of 6 acupressure points for back, neck, sciatica, energy, and sleep were taught: Ling Gu (22.05), Cheng Shan (BL 57), Feng Chi (GB 20), Huan Tiao (GB 30), Yong Quan (KD 1), and Lao Gong (PC 8). A member of the administrative team manually took attendance for each class. A link to a recording of a typical class is available in Supplementary 2.
The first author taught and streamed the class content to all treatment participants via Zoom twice weekly for 12 weeks from September 22, 2022 to December 19, 2022. Participants received guidelines and suggestions for home practice and were encouraged to complete a practice log for each class. Class recordings were available for viewing at any time to facilitate home practice. To facilitate continued participation and minimum discomfort, participants were taught tools (such as modifying range of motion and altering number of repetitions) to tailor their practice based on their needs. Individuals in both treatment and control groups continued their usual medical care throughout the study.
Measures
Baseline information included self-reported sociodemographic characteristics, height, weight, and cigarette smoking history. All primary and secondary outcome measures (described below) were collected at the baseline, 8-, 12-, and 16-week surveys via the Qualtrics platform. Adverse events were identified through feedback, phone calls, and during treatment sessions.
Primary outcome
The Oswestry Disability Index (ODI [21]) is a 10-item questionnaire assessing pain-related disability due to LBP (range 0-100; higher scores reflect increasing disability). A 5–10 point between-group difference is considered clinically small, while a 10-20-point difference is moderate, and any difference greater than 20 points is large [5].
Secondary outcomes
Pain intensity was measured using 2 visual analog scale questions (VAS [22]), one focusing on back pain and another on leg pain. Scores range from 0 to 10; higher scores indicate worse pain. Scores on the 2 pain measures were averaged to compute a total score on a 0–10-point scale. Clinically meaningful between-group differences were defined as small (0.5–1 point), moderate (1–2 points) and large (greater than 2 points) [5].
Sleep quality was measured using the Pittsburgh Sleep Quality Index (PSQI [23]). The 19 questions are used to compute 7 “component” scores, the sum of which yields 1 global score (range 0–21; higher scores correspond to poorer sleep quality). A minimal clinically important difference on the PSQI global score is 4.4 points [24].
QOL was measured using the 36-item Short Form Health Survey questionnaire (SF-36) [25]. The SF-36 assesses 8 scales, which are summed to create a global score (range 0–100; higher scores reflect greater well-being). A minimum clinically important difference on the SF-36 is 5 points [26].
Sample size
With an assumed effect size of d=0.6–0.7 and a total of 100 participants randomly assigned to either treatment or control groups, we expected to achieve power ranging from 70% (d=0.6, α=.016, 2-tailed, conservative correction for multiple testing) to 85% (d=0.7, α=.016, 2-tailed). Assuming an attrition rate of 50%, we initially aimed to recruit 200 participants. During the recruitment phase, there was greater interest in participation than the research team had anticipated, with 417 responses to the baseline and eligibility survey (of which 350 met eligibility criteria and consented to image, voice, or data collection). The online delivery platform enables us to recruit more participants without significantly increasing costs. Because of this, and to increase our safety margin against dropouts, we ultimately recruited 350 participants to facilitate a balanced design.
Statistical analysis
All analyses were conducted on the full sample with 2-sided tests and α=0.05. Intent-to-treat analyses were conducted (all available responses at each time point were included in analyses, regardless of treatment adherence). The baseline sociodemographic characteristics of the sample were compared between randomization groups using 2-sample t-tests. Linear mixed models (LMM) were fitted to each outcome (ODI, VAS, PSQI, and SF-36) to compare scores across randomization groups at baseline and 8, 12, and 16 weeks (Supplementary 2). Fixed effects were estimated for randomization group (treatment or control), time, and a group-by-time interaction. Random effects were estimated for participants to capture individual-level variation. Contrasts were calculated to test adjusted group mean differences at each time point. The t-tests and LMM analyses were conducted in the R programming language [27]. LMM analyses were conducted using the nlme package [28]. We performed multiple imputation and re-fit the models to the complete data sets. Bayesian sensitivity analyses were conducted to test the impact of priors reflecting no or adverse effect of treatment. Sensitivity analyses adding sex as a predictor were conducted. Multiple imputation and sensitivity analyses were performed in Version 8.8 of Mplus [29].
Results
The baseline survey was completed by 417 individuals, of which 350 met eligibility criteria and were randomly assigned to either the treatment or control group (175 participants assigned to each group, see Fig. 1). The 2 groups were similar on all baseline demographic and clinical variables (Table 1). Of the 175 participants assigned to treatment, 51 (29%) attended no classes, 94 (54%) 25% or fewer classes, 70 (40%) at least half of the classes, 50 (28%) 75% or more classes, and 13 (7%) all 24 classes. Of the 162 treatment group participants who attended fewer than 24 classes, 3 (2%) were due to family issues, 2 (1%) to health issues, 1 (1%) to loss of interest, 22 (14%) to scheduling conflicts, 1 (1%) to other reasons, 3 (2%) to lack of progress, and 130 (80%) did not provide a reason. At 8 weeks, 91 (52%) participants in the treatment group and 153 (87%) in the control completed assessments. At 12 weeks, 93 (53%) participants in the treatment group and 155 (89%) in the control completed assessments. At 16 weeks, 90 (51%) participants in the treatment group and 148 (85%) in the control completed assessments.

Over half the treatment group participants with missing data attended less than 25% of the classes; further, most participants who gave reasons for dropping out of the study cited scheduling conflicts. None of the demographic characteristics in Table 1 were predictive of missing data, nor were the baseline outcome measures. These findings suggest our data are likely missing at random (MAR). Therefore, we present results based on the data set with missing observations for participants who did not complete outcome measures at all time points (see Outcomes Section below regarding results of analyses based on imputed data and sensitivity analysis).
Outcomes
Model fit statistics and parameter estimates for the LMMs are presents in eTables 1-5 in Supplementary 2. Compared with the control group, the treatment group experienced statistically and clinically significantly greater improvement on the ODI at all time points, with a 4.7-point between-group difference at 8 weeks, 6.42-point difference at 12 weeks, and 8.14-point difference at 16 weeks (p<.01 for all differences, Table 2). The overall change on the ODI from baseline to 16-week follow-up within the control group was 0.45 points, while within the treatment group it was 7.31 points.

Detailed outcomes from sensitivity analyses and multiple imputation procedures are available in Supplementary 2, see eTables 6-11. Results from analyses on the complete data set from multiple imputation were generally similar to those from analyses on the data set with missing data. Sensitivity analysis testing the impact of priors reflecting no or adverse effects of treatment also produced consistent results. Sex did not exhibit a modifying effect on the treatment's impact concerning ODI, SF-36, or VAS measures. However, regarding PSQI, the effect of the treatment varied based on sex, showing that females experienced more significant improvements compared to males.
Adverse events
During the treatment period, 2 (1.6%) of 124 participants attending 1 or more of the 24 sessions reported an adverse event: one started having pain in the forearm after treatment started; the other had shoulder pain possibly due to overdoing shoulder rotations. The pain in both cases was minor and transient.
Discussion
Our randomized controlled trial found that a 12-week VDTQM treatment was effective in improving pain-related disability, pain intensity, sleep quality, and QOL in adults with LBP. Participant outcomes continued to improve 1 month after treatment was completed and reached both clinical and statistical significance for all outcomes except for sleep quality, which only reached statistical significance. Subjective experiences also mirrored these findings [41]. Given our study duration of 16 weeks, we are unable to evaluate if the effects are longer lasting. To our knowledge, this is the first study demonstrating the effectiveness of a VDTQM program for treating LBP.
The VDTQM program was delivered remotely, allowing people with a wide range of pain intensity, physical conditions, ages (21-92) and locations to participate. It yielded benefits beyond pain-related disability and pain relief, including sleep and QOL; pain and pain-related disability continued to improve even after the conclusion of treatment. These findings align with previous randomized controlled trials using in-person tai chi, qigong, and meditation integrated curricula which have demonstrated significant effects on sleep, anxiety, strength, force control, immune function, cognition and overall well-being [10,11,15,[30], [31], [32]].
Our between-group differences reflect small (ODI) to moderate (VAS) but clinically and statistically significant effects of the VDTQM program. These findings are consistent with the conclusions of a 2017 review [5], which found the effects of nonpharmacological intervention on back pain are small in pain related disability (ODI 5-10), and moderate in pain intensity (VAS 1-2). These conclusions are also in line with the system used in a review by the American College of Physicians and American Pain Society [33,34]. Two prior studies of adults [16] and retired athletes [17] with LBP exclusively included movements in their curriculum and found that tai chi reduced pain compared to control groups; Hall et al. [16] additionally reported moderate improvement in disability. One qigong study of office workers with LBP [18] focused on meditative stillness (standing and sitting) during the treatment and found it led to greater pain relief and improved disability compared to the control. The VDTQM participants demonstrated clinically significant short-term improvement in both pain and pain-related disability. A distinctive feature of our study was the focus on integrating both movement and stillness within the treatment. It was also delivered online, setting it apart from the previous studies.
Our study had limitations. First, the participants were primarily from the New York Metropolitan area and were recruited based on participation in a webinar and wellness program. All major US ethnic groups were represented with a moderate degree of over-representation of Non-Hispanic Whites and a significant over-representation of college educated individuals. Female participants outnumbered males by roughly 4:1. Only 28.5% of the treatment group participants attended 75% or more of the 24 sessions. Many participants with low adherence reported scheduling issues as the reason, and it became clear in qualitative interviews that it was not made clear enough to the participants that the sessions would be held twice (rather than once) weekly. In future studies, the research team needs to clarify the schedule of the treatment beyond email communication. Due to low adherence, there was missing data at all time points. It is possible that those who dropped out of the study experienced less improvement in their outcomes compared to those who completed the program, which could potentially make the treatment appear more effective than it truly was. However, we believe that this bias may be limited, as most participants who provided reasons for dropping out cited scheduling conflicts rather than a lack of motivation or perceived effectiveness of the treatment. Nevertheless, we cannot be certain about the reasons for dropout among those who did not provide feedback. LMMs yield unbiased results if data are MAR – that is, the missingness is independent of unobserved measurements [35]. Although sensitivity analysis suggested our data are MAR, this is ultimately impossible to determine. Readers can find multiple imputation procedures and results in section 4 of Supplementary 2 and sensitivity analysis procedures and results in section 5 of Supplementary 2. There is no consensus among statistical experts regarding how to define and conduct ITT of longitudinal randomized control trial data with missing values. Various strategies such as complete-case analysis and multiple imputation have been proposed and implemented [36]. We chose to include all available observations in our models, with participants analyzed within their assigned randomization group regardless of compliance or loss to follow up. As Detry and Ma explain [35], LMMs produce relatively unbiased estimates of treatment effects in the presence of MAR data “and additional methods for handling missing data, such as multiple imputation, are generally not required.” Pain medication use was not captured in this study and should be included in future investigations. Outcome measures were collected for 1 month post treatment. Future investigations should follow participant outcomes for a longer period after treatment concludes to understand whether the short-term improvements were limited to temporary syndrome relief. Finally, given the nature of the study, it was impossible to blind participants to group membership; however, the data analyst should be blinded in future research. We did not directly compare the effects of VDTQM to those of other evidence-based nonpharmacologic treatments. Although there are examples of other nonpharmacologic and tai chi studies which use waitlist controls[5] and the utilization of inactive controls is a common practice in behavioral interventions [37], it would be informative to include a comparison treatment that facilitates an expectation of improvement. Future investigations should include a comparison treatment in addition to a waitlist control group, as well as including an activity for the control group to create a similar expectation of improvement. In general, tai chi/qigong programs used in research are highly heterogeneous in terms of curriculum composition and instructor qualification which are essential for the quality and efficacy of the research [38]. The VDTQM program has demonstrated positive effects on various health outcomes in several controlled trials [10,11,[30], [31], [32]]. In addition, a sample class video is provided in the supplemental materials to allow other researchers to replicate the study. The instructor is a master teacher of traditional tai chi and qigong with a PhD in Kinesiology.
The growing prevalence of LBP places a burden on individuals, society, and the healthcare system [2]. This safe, adaptable, low-cost, and scalable treatment can help surmount common barriers to timely care for LBP: absence of facilities, scheduling problems, costs, and the like [3,39]. A VDTQM program could be an important nonpharmacologic resource for LBP treatment, potentially helping ease the burden on the healthcare system and expanding access to timely care, especially to people in underserved areas [8,40]. By focusing on both physical and mental modalities, VDTQM was designed with an aim to alter how individuals perceive and manage their LBP, with the goal of increasing functionality and overall well-being.
Conclusions
A 12-week virtually delivered integrated tai chi, qigong, and meditation program resulted in small to moderate improvement in pain-related disability, pain intensity, QOL and sleep quality in adults with LBP. Improvements in all outcomes were sustained for at least 1 month after the conclusion of the treatment. The results of our study indicate that VDTQM may be a viable treatment option for patients with LBP.
