Persistent pain after treatment for breast cancer is a major clinical problem, affecting 25-60 % of the patients and is a source of considerable physical disability and psychological distress. Thus, the development of novel interventions to improve pain management for these patients is of clinical importance. Resistance training (RT) is a promising tool to combat a variety of undesirable adverse effects due to breast cancer treatment. Further, research suggests that it may also be able to provide pain-relieving benefits.
Hypothesis: Resistance training will improve pain perception and physical function in the short- and long term compared to a non-training control group.
Breast cancer is the most common cancer in women worldwide with more than a million new cases diagnosed every year [1]. Fortunately, due to better treatment options, the population of long-term survivors is increasing. This poses new demands for knowledge on how to manage late effects to the treatment regimen. Persistent pain after treatment for breast cancer is a common and underestimated problem as well as it can be a source of considerable physical disability and psychological distress [2]. Hence, the development of novel interventions to improve pain management is of high clinical relevance. Resistance training (RT) is a promising clinical therapeutic tool to improve a variety of adverse effects to breast cancer treatment [3] and may provide several pain-relieving benefits [4]. However, the efficacy of this modality for managing persistent pain after breast cancer treatment is currently unclear. Therefore, the purpose of this project is to investigate if individualized RT can modulate persistent pain after breast cancer treatment, thereby improving our understanding of how this modality may benefit patients and contribute to clinical guidelines for pain management in this clinical population.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Training | Experimental | Participants with persistent pain after breast cancer treatment will receive 24 sessions of individualized progressive total body resistance training, supervised by a certified strength and conditioning specialist. |
|
| Control | Other | Participants with persistent pain after breast cancer treatment will be instructed to continue their everyday lifestyle and be encouraged not to engage in new forms of exercise or physical activity throughout the study period. |
|
| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Training | Other | The experimental group will perform a supervised progressive resistance training program, with five exercises for the upper- and lower body (box squat, bench press, trap bar deadlift, bench pull and lat pulldown), 2x/week for a 12 week period. The program will utilize a flexible progression system through three distinct training phases; 1) 2-4 sets of 10-12 repetitions, 2) 2-4 sets of 6-8 repetitions, 3) 2-4 sets of 2-4 repetitions. Number of sets are adjusted within session according to daily readiness while load is adjusted within and between sessions according to number of reps performed. A 3-5min rest period is provided throughout the program. |
| Measure | Description | Time Frame |
|---|---|---|
| Change in pain sensitivity, assessed through pressure pain thresholds. | Between group comparisons of treatment effect (change in pressure pain thresholds) from baseline to follow-up) will be performed. Pressure pain thresholds will be collected with a pressure algometer with a progressive increment in pressure of 30kPa. | Baseline and at 3, and 6 months |
| Change in pain intensity, assessed through a 11 point numeric rating scale (0 = no pain, 10 = worst pain imaginable). | Pain intensity is collected in two different contexts; 1) recollection for the past 3 months and 2) movement evoked pain during testing and training. | Baseline and at 3, and 6 months |
| Measure | Description | Time Frame |
|---|---|---|
| Muscular strength assesses through a 1 repetition maximum (1RM) | 1RM box squat, bench press, trapbar deadlift, bench pull and lat pulldown conducted in accordance with the recommendations of the American College of Sports Medicine (ACSM) | Baseline and at 3, and 6 months |
| Active shoulder range of motion assessed with a universal goniometer. |
| Measure | Description | Time Frame |
|---|---|---|
| Summative process evaluation | The summative process evaluation include the following: 1) Context of the intervention described qualitatively, 2) the dose delivered as %'age of the planed sessions effectively implemented, 3) dose received as %'age of planned sessions effectively received, 4) fidelity measured through the following items: (1) whether the training groups (i.e. same participants every session) during training sessions were consistent; (2) whether the instructors delivered all their sessions as initially scheduled; (3) whether warm-up and training were offered in accordance with the time schedules initially planned; (4) whether the time schedule were respected by participants and instructors and 5) satisfaction, rated as level of agreement with a series of statements on a five-point likert scale 1=strongly disagree, 2=disagree, 3=uncertain, 4=agree, and 5=strongly agree. |
