Association between Shoulder Range of Motion and Pain Catastrophizing Scale in Breast Cancer Patients after Surgery

Altered upper limb motor behavior in breast cancer survivors and its relation to pain: A narrative review

Breast cancer is the most commonly diagnosed cancer among women and many women suffer from persistent physical and psychological complaints following their cancer treatment. Altered motor behavior at the shoulder region and upper limb, that is, alterations in movement patterns, spatiotemporal movement characteristics and muscle activation patterns, is a common physical consequence of breast cancer treatment, that can have a clear impact on daily life functioning and quality of life. Furthermore, altered upper limb motor behavior is suggested to relate to upper limb pain, which is very commonly reported in breast cancer survivors (BCS). This review, prepared according to the SANRA guidelines, looks into the current understanding of alterations in motor behavior at shoulder and upper limb in BCS, by discussing the factors related to this altered behavior. In this, we specifically focus on the relation between motor behavior and pain. Results of our search show that cancer treatment modality is predictive for shoulder range of motion. Furthermore, single prospective studies show depressive symptoms, living alone, being non-white and low physical activity levels as predicting factors for reduced shoulder range of motion. Pain as factor related to altered motor behavior is only assessed in cross-sectional research, limiting its interpretation in context of being cause or consequence of motor behavioral adaptations, and on the underlying mechanism explaining their relation. It is concluded that studies which explain the mechanisms how and in which subgroup of BCS motor behavioral alterations are associated with pain at the upper limb, are necessary in future.

Additional intraoperative subpectoral plane block vs conventional pain control: A comparison of shoulder movement in patients with mastectomy

PURPOSE

Shoulder pain is common among mastectomy patients, with limiting shoulder mobility and negatively affecting their quality of life. Pectoral nerve blocks (PECs) have demonstrated efficacy in providing postoperative analgesia. We hypothesized that these nerve blocks could improve shoulder movement in patients undergoing mastectomy.

METHODS

This prospective, randomized, double-blind controlled trial enrolled female participants diagnosed with breast cancer and scheduled for mastectomy. Participants were randomly assigned to either the conventional analgesia group or the intervention group. In the intervention group, a PECs II block was applied prior to skin closure following a mastectomy. This study's primary outcome was the assessment of shoulder movement ratios in 5 different positions (forward elevation, external rotation, arm abduction, internal rotation, and cross-body adduction), which were recorded before surgery, at 24-h, 48-h, and 72-h intervals postoperatively, with follow-up at 1 month, 2 months, 3 months, and 6 months.

RESULTS

A total of 59 participants were included in the final analysis. Patients who underwent mastectomy with PECs II block exhibited better shoulder movement in terms of external rotation and arm abduction from the early post-surgery up to 6 months postoperatively. Shoulder forward elevation also showed superior gains during the early postoperative period, with statistical significance observed after 1 month following the surgery. However, no significant differences were found between the two groups in terms of internal rotation and adduction movements of the shoulder.

CONCLUSIONS

Compared to conventional analgesia, intraoperative pectoral nerve block under direct vision enhances shoulder mobility in forward elevation, external rotation, and arm abduction after mastectomy in breast cancer patients.

Mirror therapy effect on shoulder pain and disability and quality of life of mastectomy women: a randomized clinical trial

PURPOSE

To investigate mirror therapy (MT) influence on shoulder pain/disability and quality of life in mastectomy women.

MATERIALS AND METHODS

Sixty unilateral mastectomy women were recruited and randomly assigned to an MT group (N = 30) or a sham therapy (ST) (N = 30). Women in the MT and ST group attended a nurse-led, unsupervised, 30 min a day, five days a week, and at home training program for three weeks with and without a mirror, respectively. Shoulder pain and disability scale and QOL outcomes were assessed at baseline and 3 months after intervention.

RESULTS

Shoulder pain and disability were significantly improved in the MT group but there was not meaningful difference between groups in the EORTC-QOL scales except for some functional scores of QLQ-BR23 scale in the MT group after 3 months follow-up.

CONCLUSIONS

Nurses should instruct MT as a rehabilitation program to mastectomy patients during or after hospitalization to reduce their post-op shoulder pain and disability. This intervention may have also positive impact on their self-care outcomes. It is recommended that further studies should be performed with nurse-supervised exercises, a validated tool for measuring QOL for a long period after surgery, and a longer follow-up period at least for 6 months.Implication for rehabilitationThis study aimed to investigate whether an unsupervised, nurse-led mirror therapy (MT) can alleviate shoulder pain and disability of mastectomy patients and improve their quality of life.Our findings indicated that nurse-led MT as a novel rehabilitation option for mastectomy patients, may reduce shoulder pain and disability even after long period after the surgery.Rehabilitation centers can equip rooms for MT so breast cancer women can use it immediately after mastectomy.Mirror therapy can be used as a rehabilitation method for mastectomy patients because it is easy-to-use, inexpensive, and without the need to attend a rehabilitation center.Rehabilitation centers can provide mirrors along with nursing instructions to women who want to use this method at home.

Risk factors for long-term arm morbidities following breast cancer treatments: A systematic review

PURPOSE

To examine the risk factors for arm morbidity following breast cancer treatments, taking a broad view of all types of physical morbidity, including prolonged pain, lymphedema, decreased range of motion, and functional limitations.

METHODS

A systematic literature review was performed according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Guidelines. Studies exploring the risk factors for prolonged arm morbidity following breast cancer surgery and treatments were included. The studies were assessed independently according to pre-eligibility criteria, following data extraction and methodological quality assessment.

RESULTS

1,242 articles were identified. After removing duplicates, the full texts of 1,153 articles were examined. Sixty-nine of these articles met the criteria and were included in the review. These 69 articles identified 29 risk factors for arm morbidity following treatments for breast cancer. The risk of bias was evaluated using NIH study quality assessment tools. The studies reviewed were published between 2001 and 2021 and included a total of 22,886 patients who were followed up for between three months and 10 years.

CONCLUSIONS

The main risk factors for long-term morbidity are removal of lymph nodes from the axilla, body mass index >30, having undergone a mastectomy, the stage of the disease, radiation therapy, chemotherapy, infection and trauma to the affected arm after surgery. An understanding of the risk factors for prolonged arm morbidity after surgery can help doctors and therapists in making personalized decisions about the need and timing of rehabilitation treatments.

The Contribution of Cancer-Specific Psychosocial Factors to the Pain Experience in Cancer Survivors

Palliative care teams are increasingly called up to manage chronic pain in cancer survivors. Chronic pain is common in cancer survivors and is heavily influenced by biopsychosocial factors. This study aimed to determine the relative contribution of unique cancer-specific psychosocial factors, pain catastrophizing, and multisite pain to the pain experience in 41 cancer survivors who completed curative cancer treatment. To test the research hypotheses, a series of nested linear regression models were used with likelihood ratio testing to test the individual and collective contribution of cancer-specific psychosocial factors (fear of cancer recurrence, cancer distress, cancer-related trauma), pain catastrophizing, and the number of pain sites on the pain experience. The results indicate pain catastrophizing and multisite pain explained a significant degree of variance in pain interference scores ( P < .001) and pain severity ( P = .005). Cancer-specific psychosocial factors did not significantly predict variability in pain interference ( P = .313) or pain severity ( P = .668) over and above pain catastrophizing and the number of sites of pain. In summary, pain catastrophizing and multisite pain contribute to the chronic cancer-related pain experienced by cancer survivors. Palliative care nurses are well positioned to improve chronic pain among cancer survivors by assessing and treating pain catastrophizing and multisite pain.

Shoulder function and health outcomes in newly diagnosed breast cancer patients receiving surgery: a prospective study

BACKGROUND

Breast cancer surgery is associated with upper-body morbidities that may last several years postsurgery. Research has not determined if the type of surgery leads to differential effects on shoulder function, activity levels, and QoL during the early rehabilitation period. The main objective of this study is to examine changes in shoulder function, health, and fitness outcomes from the day before to surgery to 6 months postsurgery.

PATIENTS AND METHODS

We recruited breast cancer patients (N = 70) scheduled to receive breast cancer surgery at Severance Hospital in Seoul to participate in this prospective study. Shoulder range of motion (ROM) and upper body strength, the disabilities of Arm, Shoulder, and Hand (quick-DASH), body composition, physical activity levels, and QoL were measured at baseline (presurgery) and then weekly for 4 weeks, and at 3 months and 6 months postsurgery.

RESULTS

During 6 months after surgery, shoulder ROM was reduced only affected arm while shoulder strength was significantly declined in both affected and unaffected arms. Within 4 weeks postsurgery, patients who underwent total mastectomy were significantly less recovered than patients with partial mastectomy in ROM of flexion (P < .05) and abduction (P < .05). However, shoulder strength of both arms observed no interaction between surgical type and time. We observed significant changes in body composition, quick-DASH score, physical activity levels, and QoL from presurgery to 6-months postsurgery.

CONCLUSIONS

Shoulder function, activity levels, and QoL improved significantly from surgery to 6-months postsurgery. Surgery type influenced changes in shoulder ROM.
