Interventions

  • Mindfulness-based stress reduction (MBSR) — BEHAVIORAL
    Mindfulness-based stress reduction (MBSR) is delivered in 8 weekly 2.5-hour group sessions and one day-long retreat that occurs after the 6th session. MBSR teaches to become more aware of thoughts, feelings, and sensations, and to skillfully respond to stressors. Each of the sessions includes education about mindfulness and stress; experiential mindfulness practice, and discussion of participants' experiences with mindfulness practice. Participants learn formal mindfulness practices (e.g., meditation, yoga, body scan, body scan) as well as informal such as awareness of breath, thoughts, or emotions, and mindfulness of daily activities. Participants will receive digital audio (MP3) downloads with guided MM practices, a home practice manual, and handouts with each week's assignments. Daily home practice will consist of 40-45 minutes of recorded practice. Participants will log their daily practice. If a participant misses a class, it is possible to make up the class on a different day.
  • Health enhancement program (HEP) — BEHAVIORAL
    8-week health enhancement program (HEP) is designed to provide a structurally parallel, active control intervention to MBSR with health benefits in their own right, while omitting any components of mindfulness. HEP matches MBSR in structure and content, and in parallel to MBSR, consists of music therapy, nutritional education, posture and balance movements, walking and stretching. Work with all practices with group discussion and exercises during an all-day "spa day" will match the all-day retreat in MBSR. HEP participants will meet with a health educator in a group setting for 8 weekly 2.5-hour sessions. Participants will receive MP3 downloads on an MP3 player with recordings of health education topics, a home listening manual, and weekly handouts with each week's listening assignments. Participants will listen to these MP3 recordings daily for 40-45 minutes and log their daily adherence.
  • Transcutaneous Vagus Nerve Stimulation (tVNS) — DEVICE
    Participants self-administer tVNS twice per day for 8 weeks. tVNS is delivered using a multi-use, hand-held, rechargeable portable device consisting of a rechargeable battery, signal generating and amplifying electronics, and a button for operator control of the stimulation intensity. Conductive gel is applied to the stainless steel round discs on the device and placed vertically on the skin overlying the vagus nerve under the angle of the mandible, between the trachea and sternocleidomastoid muscle. A low-voltage electrical signal is delivered consisting of 5-kilohertz (kHz) sine wave series for 1 ms and repeated every 40 ms, with a maximum delivery of 24 V and 60 milliampere (mA) output. Stimulation amplitude is adjusted by the user and is increased until there is a vibration and slight muscle contraction in the lower face or neck. Stimulation is delivered for 2 minutes on the left side of the neck, and 2 minutes on the right side of the neck, for a total 4 minutes per one dose.
  • Sham-transcutaneous Vagus Nerve Stimulation (tVNS) — DEVICE
    Participants self-administer sham-tVNS twice per day for 8 weeks. Sham stimulation will be delivered using a sham device that is identical in appearance and function, but programmed to produce a lower frequency biphasic signal that can be felt by the participant without actually stimulating the vagus nerve.

Study Details

This study will test whether mindfulness meditation (MM) improves sympathetic function in chronic kidney disease (CKD) and whether transcutaneous vagus nerve stimulation (tVNS) optimizes the sympatho-inhibitory effects of mindfulness meditation (MM) and restores autonomic balance in CKD patients.

Arms

  • Experimental: Mindfulness-Based Stress Reduction (MBSR)
    Mindfulness-Based Stress Reduction (MBSR) tis designed to provide education about mindfulness and stress; experiential mindfulness practice, and discussion of participants' experiences with mindfulness practice. MBSR is delivered in 8 weekly 2.5-hour group sessions and one day-long retreat that occurs after the 6th session.
  • Active Comparator: Health enhancement program (HEP)
    Health enhancement program (HEP) is designed to provide a structurally parallel, active control intervention to MBSR with health benefits in their own right, while omitting any components of mindfulness. HEP participants will meet with a health educator in a group setting for 8 weekly 2.5-hour sessions with a day-long retreat.
  • Experimental: MBSR+tVNS
    Mindfulness-Based Stress Reduction (MBSR) tis designed to provide education about mindfulness and stress; experiential mindfulness practice, and discussion of participants' experiences with mindfulness practice. MBSR is delivered in 8 weekly 2.5-hour group sessions and one day-long retreat that occurs after the 6th session. Transcutaneous vagus nerve stimulation (tVNS) is a simple, noninvasive, self-administered adjunctive therapy, that may enhance the sympatho-inhibitory effects of mindfulness meditation (MM) in chronic kidney disease (CKD) .
  • Active Comparator: MBSR+sham-tVNS
    Mindfulness-Based Stress Reduction (MBSR) tis designed to provide education about mindfulness and stress; experiential mindfulness practice, and discussion of participants' experiences with mindfulness practice. MBSR is delivered in 8 weekly 2.5-hour group sessions and one day-long retreat that occurs after the 6th session. Sham stimulation will be delivered using a sham device that is identical in appearance and function to tVNS, but programmed to produce a lower frequency biphasic signal that can be felt by the participant without actually stimulating the vagus nerve.
  • Experimental: HEP+tVNS
    Health enhancement program (HEP) is designed to provide a structurally parallel, active control intervention to MBSR with health benefits in their own right, while omitting any components of mindfulness. HEP participants will meet with a health educator (a registered dietician) in a group setting for 8 weekly 2.5-hour sessions. Transcutaneous vagus nerve stimulation (tVNS) is a simple, noninvasive, self-administered adjunctive therapy, that may enhance the sympatho-inhibitory effects of mindfulness meditation (MM) in chronic kidney disease (CKD).
  • Active Comparator: HEP+sham-tVNS
    Health enhancement program (HEP) is designed to provide a structurally parallel, active control intervention to MBSR with health benefits in their own right, while omitting any components of mindfulness. HEP participants will meet with a health educator in a group setting for 8 weekly 2.5-hour sessions. Sham stimulation is be delivered using a sham device that is identical in appearance and function to tVNS, but programmed to produce a lower frequency (0.1 Hz) biphasic signal that can be felt by the participant without actually stimulating the vagus nerve.
