Effects of Yoga on Cognitive and Immune Function in Colorectal Cancer
- Conditions
- Colorectal Neoplasms
- Interventions
- Other: YogaOther: Physical Activity
- Registration Number
- NCT02564835
- Lead Sponsor
- University of Michigan
- Brief Summary
The purpose of this study is to determine if individuals with colorectal cancer enjoy yoga and to begin to assess whether yoga is effective in improving attention and immune function in individuals with colorectal cancer compared to physical activity and usual care.
- Detailed Description
The proposed study will use a prospective RCT pilot design with three arms (yoga, resistance and flexibility exercise, usual care) and a total of 60 men and women who have completed therapy (\> 6 months post primary or adjuvant therapy) to accomplish the specific aims. Equal numbers of men and women will be randomized into each arm of the study. Participants will be tested before, immediately after, and 3-months after treatment or similar time points for the usual care group. After data has been collected, participants who were randomized to the resistance and flexibility exercise group (active control group) or to the usual care group will be provided with the opportunity to participate in the yoga intervention.

Group Intervention Description Yoga Yoga The Yoga Program includes two 90-minute classes every week tor a total of 12 weeks. Physical Activity Physical Activity The Physical Activity Program includes two 90-minutes classes every week for a total of 12 weeks.The intervention is based on the Exercise for People Living with Cancer program and will include nine resistance exercises (e.g. standing push up, squats, standing leg curl) and 8 flexibility exercises (e.g. shoulder stretch, quadriceps stretch, hamstrings and lower back stretch) targeted for the whole body as well as a brief warm up and cool down (walking).
- Primary Outcome Measures
Name Time Method Program Evaluation At the end of the 12-week yoga and physical activity programs. The program evaluation was developed by the investigator to measure the participant experience and satisfaction with the interventions.
- Secondary Outcome Measures
Name Time Method Digit Span Change from baseline to 6 months Digit Span asks participants to repeat a series of numbers in the order they were given (Digit Span Forward) or reverse order (Digit Span Backward). The score is the number of digits recalled in the correct order before two failed trials. Digit Span is a test of attention and cognitive control.
Attention Network Test Change from baseline to 6 months. The Attention Network Test is a computerized test that asks participants to determine the direction of an arrow in the center of the screen (left or right). The center arrow can be located above or below the center fixation and is accompanied by flankers and cues. Overall attention and the three networks are assessed by measuring accuracy and response times for correct answers and how response times for correct answers are influenced by flankers, alerting cues, and spatial cues.
Digit Symbol Substitution Test Change from baseline to 6 months The Digit Symbol Substitution Test provides participants with a key of numbers associated with symbols and ask participants to fill in numbered blank squares with the appropriate symbol. The score is the number of blank square filled in within 120 seconds. Digit Symbol Substitution test is a test of attention and cognitive control.
Trail Making Test Change from baseline to 6 months The Trail Making Test asks participants to draw a line connecting numbered circles (Part A) and a line connecting numbered circles and letters (Part B). The score is the time taken to complete the task. The Trail Making Test is a test of attention and cognitive control.
Attentional Function Index Change from baseline to 6 months The Attentional Function Index is a questionnaire that asks participants to rate their function on everyday tasks requiring attention and cognitive control from 0 (not at all) to 10 (extremely well or a great deal). The score is the average of 13 questions. The internal consistency ranges from 0.76 to 0.94 in individuals with cancer.
Functional Assessment of Cancer Therapy - Cognitive Function Change from baseline to 6 months The Functional Assessment of Cancer Therapy-Cognitive Function is a questionnaire that measures perceived cognitive function and impact on quality of life from 0 (not at all) to 4 (very much). It includes 27 items grouped into 5 subscales The internal consistency is 0.96 on each subscale in individuals with cancer.
Pro-inflammatory Markers Change from baseline to 6 months Serum levels of interleukin-1 beta, tumor necrosis factor-alpha, interleukin-6, interleukin-8, interleukin-12, interleukin-1 receptor antagonist, soluble tumor necrosis factor-receptor II, and c-reactive protein will be determined by cytometric bead array assay on a Luminex analyzer (MPXHYCTO-60K, Millipore; LXSAH, R \& D Systems). Serum levels of neopterin will be determined by enzyme-linked immunosorbent assay (RE59821, IBL International). Blood samples will be collected between 8 am and 10 am.
