Somatic Yoga and Meditation for Cancer Survivors With Pain From Neuropathy

Study Overview
=================
Brief Summary
-----------------
Chemotherapy-induced peripheral neuropathy syndrome (CIPN) causes significant pain in hands and feet and is an adverse effect of treatment. Few non-pharmacological interventions have been tested and individuals experience CIPN symptoms years after treatment. This is the first study to explore a somatic yoga and meditation (SYM) intervention on functional outcomes and quality of life in cancer survivors.

Detailed Description
-----------------
Pain is a common symptom associated with cancer; 75-90% of cancer patients experience pain during their illness and up to 50% of that pain is undertreated. Unrelieved pain leads to increased levels of the stress hormone cortisol. Chemotherapy-induced peripheral neuropathy syndrome (CIPN) causes significant pain in hands and feet and is a common, adverse effect of several chemotherapeutic agents. It can lead to abrupt discontinuation of treatment, and severely affects the quality of life. CIPN is a particularly important adverse effect because it may compromise the ability to tolerate chemotherapy and become a serious, long-lasting, and even permanent debility. CIPN symptoms may persist many years after treatment; together with worse function, greater disability, and more falls which is complicated by the aging process. Clinically, CIPN presents as deficits in sensory, motor, and function which develop in a glove and stocking distribution. While chemotherapy improves the likelihood of disease-free survival, the result of CIPN may cause decreased walking speed and balance observed after the first chemotherapy cycle and progresses with cumulative exposure. These functional deficits are mirrored with increased symptom severity. CIPN is associated with potential fall risk with aging cancer survivors and increased functional disability. Few interventions have been tested for impact from CIPN. Yoga is a popular movement therapy, often used by cancer survivors for symptom management. Several studies demonstrate the promising effects of yoga on sleep, fatigue and quality of life (QOL) in cancer survivors. However, no study has rigorously investigated its effects on CIPN and quality of life. This study will explore the preliminary therapeutic effects of an 8-week somatic based yoga and meditation (SYM) program and 15-25 cancer survivors with CIPN will be enrolled into a small pilot study. This will include 16 sessions of yoga designed specifically to minimize injury, promote flexibility/ balance and to allow you to maximize their specific functional goals. All types of cancer diagnoses resulting in CIPN will be enrolled in a single arm feasibility trial. SYM will be provided twice a week for 8 weeks for 1.5 hours. You will complete surveys at the beginning and end of 8 weeks and receive a home-based SYM and write journal entries to determine your perspectives of the intervention.

Design Details

Primary Purpose: Treatment
Intervention Model: Single Group Assignment
Interventional Model Description: Criteria for enrollment included cancer survivors age 18 or older; any type or stage of cancer, currently completed all treatment with no current evidence of disease; at least mild peripheral neuropathy symptoms (either sensory or motor) as rated on the Patient Neurotoxicity Questionnaire (PNQ), attributable to chemotherapy intervention as a component of cancer treatment. Exclusion criteria included active cancer disease or current cancer treatment; co-morbidities such a diabetes or prior history of peripheral neuropathy from any cause. All participants will be screened with the physical activity readiness questionnaire (PAR-Q) to determine the safety or possible risk of exercising based on health history, current symptoms and risk factors. Somatic yoga and meditation (SYM) will be provided during 16 sessions/8 weeks for 1.5 hours and participants will complete home-based SYM and journal entries.
Masking: None (Open Label)


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Somatic Yoga and Meditation (SYM)<br>Participants will engage in 16 sessions of somatic yoga and meditation with appropriate props as needed over 8 weeks and continue with a home practice. Application of SYM throughout activities of daily living is reinforced. All sessions are facilitated by trained yoga therapists. | Behavioral: Somatic Yoga and Meditation (SYM)<br>* A Hanna somatics and somatic yoga and meditation (SYM) protocol was designed to address sensory-motor amnesia and reduce trauma which creates reflex patterns that lead to chronic muscular contractions. The movements use voluntary muscular contraction and slow controlled eccentric contraction, with the constant focus on sensation to increase the resting length of muscles. Movements are performed slowly and gently with the least possible effort and are never forced. The protocol is endorsed by the US Army Surgeon General as treatment for chronic pain. The meditations are trauma informed and evidence based supporting pain modulation, healing and well-being.<br>* Other names: Yoga4CIPN (Y4CIPN);|

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Sit and Reach (SR) | The Sit and Reach Test (SR) is the most-widely used measure of hamstring and low back flexibility, examining the maximal reach an individual can make in a long-sitting position. The SR has established norms by the American College of Sports Medicine, with a score of 16 and 15 for adults 46-55 years old and 56-65 years old respectively in the 50th percentile. Individuals are asked to maintain a long-sit position on the floor while safely reaching forward as far as possible with their shoes removed, feet flat against the table, and legs straight. Three trials are averaged and higher scores indicate greater flexibility. | Change from baseline flexibility at 8 weeks | 
| Forward Reach (FR) | The Functional Reach test (FR) test examines the balance of individuals with respect to the patient's limit of stability. Each participant is instructed to flex the test arm forward to 90˚ and to reach forward as far as possible before taking a step. The reach is determined by the total excursion of the third metacarpal from the starting point to the point just before balance is lost. An average of 3 measurements is used as the final score. FR has demonstrated strong reliability and validity for measuring postural control in reaching forward during standing. The FR test has shown criterion validity, predictive validity, test-retest reliability, and inter-rater reliability for younger and older adults. It has also been shown to possess predictive validity for falls. | Change from baseline balance at 8 weeks | 
| Timed Up and Go (TUG) | The Timed Up and Go (TUG) is a standardized test that measures physical function in sitting to standing, walking and returning to the seated position. Participants are instructed to stand up from a chair, walk three meters as quickly and safely as possible, turn around, walk back and sit down. The test is timed and longer time indicates worse performance. Nine seconds is the cutoff for high risk of falls. | Change from baseline walking speed at 8 weeks | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Brief Pain Inventory (BPI) | The BPI is a patient reported outcome measure that assesses severity of pain, impact of pain on daily function, location of pain, pain medications and amount of pain relief in the past 24 hours or the past week. It responds to both behavioral and pharmacological pain interventions and takes 5 minutes to complete. Scoring algorithm: worst pain or the arithmetic mean of the four severity items can be used as measures of pain severity; the arithmetic mean of the seven interference items can be used as a measure of pain interference. Reliability: Cronbach alpha reliability ranges from 0.77 to 0.91 | Change from baseline pain at 8 weeks | 
| Patient Neurotoxicity Scale (PNQ) | Patient perception of sensation and weakness attributed to CIPN.The PNQ is two self-reflective questions and quantifies the symptoms (sensation) and perceived weakness from CIPN 1) Do you have numbness, pain, or tingling in your hands or feet? 2) Do you have weakness in your arms or legs? These two items are rated 1-5 on the following scale: 1 = No, 2 = Mild, 3 = Moderate, 4 = Moderate-to-Severe, and 5 = Severe. The PNQ total score ranges from 2 to 10, with a high total score indicating severe CIPN symptoms. A PNQ total score of 2 is defined as grade A; 3-4, as grade B; 5-6, as grade C; 7-8, as grade D; and 9-10, as grade E | Change from baseline sensation and strength at 8 weeks | 
| Perceived Stress Scale (PSS) | Each item is rated on a 5-point scale ranging from never (0) to almost always (4). Positively worded items are reverse scored, and the ratings are summed, with higher scores indicating more perceived stress. Individual scores on the PSS can range from 0 to 40 with higher scores indicating higher perceived stress. ► Scores ranging from 0-13=low stress. ► Scores ranging from 14-26 = moderate stress. ► Scores ranging from 27-40 = high perceived stress. | Change from baseline stress at 8 weeks | 
| Pittsburgh Sleep Quality Index (PSQI) | The Pittsburgh Sleep Quality Index (PSQI) is an effective instrument used to measure the quality and patterns of sleep in adults. It differentiates poor from good sleep quality by measuring seven areas (components): subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbances, use of sleeping medications, and daytime dysfunction over the last month. In scoring the PSQI, seven component scores are derived, each scored 0 (no difficulty) to 3 (severe difficulty). The component scores are summed to produce a global score (range 0 to 21). Higher scores indicate worse sleep quality. | Change from baseline sleep at 8 weeks | 
| Functional Assessment of Cancer Therapy/Gynecologic Oncology Group-Neurotoxicity (Fact/GOG-Ntx) | The FACT/GOG-Ntx contains 11 items scored from 0-4, and scores are summed for a range of 11-44. Questions on the Ntx subscale pertain to the feeling of weakness all over, numbness or tingling in the hands or feet, and difficulty buttoning their buttons. Reliability was measured using Cronbach alpha of greater than 0.7 and higher scores indicate greater severity of symptoms. | Change from baseline quality of life at 8 weeks | 
| Falls Efficacy Scale (FES) | The FES is a 10 item scale where each item is rated on a scale of 1-10. A score of 10 signifies no confidence in these activities; a score of 1 indicates confidence. Out of a total score of 100, a score of 70 or above indicates the individual has a fear of falling. | Change from baseline fear of falling at 8 weeks |
