Although physical activity (PA) is commonly used to manage symptoms and enhance quality of life (QOL) in cancer survivors, relatively little is known regarding the benefits in advanced multiple myeloma (MM). The primary aims of the Physical Activity in Advanced Cancer Treatment (PAACT) intervention were to examine (1) program feasibility and (2) potential impact on patient outcomes. It is hypothesized that an exercise intervention will be feasible and potentially impactful.
While the introduction of novel and more effective treatments has seen improved survival in multiple myeloma (MM), the aggressive nature of the disease and these corresponding agents can have a debilitating impact on quality of life (QOL). Exercise can help manage symptoms and enhance QOL in cancer survivors, however relatively little is known regarding the feasibility or benefits of exercise in MM. The purpose of this study was to examine the feasibility of a group- and home-based exercise intervention for individuals with advanced MM. In this single arm study, advanced MM patients (DS stage II-III) participated in a 12-week aerobic and resistance training intervention, with the option of palliative care consultation. Participants attended once weekly supervised group exercise classes and received individually tailored home exercise booklets. Validated measures of physical functioning and patient-reported outcomes, including QOL, fatigue, anxiety, depression, and self-compassion were obtained at baseline and 12-weeks (post-intervention). Optional semi-structured interviews were conducted halfway (week 6) and at the end of the intervention (week 12)

Feasibility of physical activity program as measured by participant recruitment rate.
Recruitment as defined by the proportion of patients who participate in the study, out of the total number of eligible patients.
Time frame: 3 months
Feasibility of physical activity program as measured by attendance of group exercise classes.
Attendance is defined by the number of weekly group-exercise classes attended.
Time frame: 12-weeks
Feasibility of physical activity program as measured by attrition rate.
Attrition is defined as the number of participants who dropped out of the program after completing the baseline assessment.
Time frame: 12-weeks
Feasibility of physical activity program as measured by safety (as measured by incidence of patient reported adverse events).
Safety is described as any adverse event reported by the participants during the 12-week program or fitness assessments, related to program participation.
Time frame: 12-weeks
Change from Baseline Upper Body Muscular Strength (in kilograms) as measured by a grip strength test using a hand dynamometer at 12 weeks.
Total grip strength in kilograms is recorded as the sum from the best score of two trials recorded for each hand. Differences between baseline and post-intervention assessments are evaluated.
Time frame: Baseline (week 0) and 12 weeks
Change from Baseline Functional lower body strength (in number of repetitions) as measured by the Chair stand test at 12 weeks.
Chair stand test records the number of times a participant can stand from a seated position in 30 seconds. Differences between baseline and post-intervention assessments are evaluated.

Change from Baseline Lower Body Flexibility (in centimeters) as measured by the Chair Sit and Reach flexibility test at 12 weeks.
In the Chair Sit and Reach Flexibility test, lower body flexibility is assessed by having the participant sit on the edge of a seat. The participant extends the leg being tested in front of the hip, with the heel on the floor and the ankle dorsiflexed approximately 90 degrees. The participant flexes the untested leg so that the sole of the foot is flat on the floor about 6 to 12 inches to the side of the body's midline. With the extended leg as straight as possible and the hands on top of each other (palms down), the participant slowly bends forward at the hip joint, keeping the spine as straight as possible and the head in normal alignment (not tucked) with the spine. The participant reaches down the extended leg, trying to touch the toes, and holds this position for 2 sec. A ruler is ran parallel to the participant's lower leg. Two practice trials are allowed followed by two test trials.The best measurement is taken.
Time frame: Baseline (week 0) and 12 weeks
Change from Baseline Upper Body Flexibility (in centimeters) as measured by the Back-Scratch Flexibility test at 12 weeks.
In the Back-Scratch Flexibility test, upper body flexibility is assessed by asking the participant to reach, with the preferred hand (palm down and fingers extended), over the shoulder and down the back while reaching around and up the middle of the back with the other hand (palm up and fingers extended). The participant is allowed two practice trials followed by two test trials.The best measurement is taken.
Time frame: Baseline (week 0) and 12 weeks
Change from Baseline Mobility (in seconds) as measured by the 8-foot Timed Up and Go test at 12 weeks.
The 8-foot Timed Up and Go test measures the time to move from a seated position, walk 8 feet, and return to a seated position.The best of two trials is taken.
Time frame: Baseline (week 0) and 12 weeks
Change from Baseline Balance (in seconds) as measured by a one-foot balance test at 12 weeks.
Participant's Balance is assessed by measuring the time the participant is able to stand on one-foot. Both feet measured. A 45-second cut-off time is implemented.
Time frame: Baseline (week 0) and 12 weeks
Change from Baseline Aerobic Capacity (in meters) as measured by the six-minute walk test at 12 weeks.
In the Six-Minute Walk Test, participants are instructed to walk as far as they can for 6 min around a track. Distances are recorded to the nearest 0.5 m.

Change from Baseline Quality of Life as measured by the The Functional Assessment of Cancer Therapy- Multiple Myeloma (FACT-MM) questionnaire at 12 weeks.
The Functional Assessment of Cancer Therapy- Multiple Myeloma (FACT-MM) questionnaire is comprised of the 27-item FACT-General (FACT-G) scale, which provides information on physical, social, emotional, and functional well-being domains in conjunction with 14 MM-specific supplementary questions. The combined subscales of physical, functional, and MM specific domains contribute to the Trial Outcome Index (TOI) score (range of 0-112). The questionnaire is rated on a 5-point Likert scale, and components can be combined to create a total score, with increases in scores representing improved quality of life.
