The Effects of Massage Therapy in Decreasing Pain and Anxiety in Post-Surgical Patients With Breast Cancer: A Systematic Review and Meta-Analysis.

Background: Massage therapy is an effective non-pharmacological intervention in treating pain and anxiety of patients with cancer. Prior studies have reviewed the benefits of massage therapy in patients with breast cancer undergoing chemotherapy, radiation, and other patient-specific cancer treatments. What has yet to be examined is the effects of massage therapy on the pain and anxiety of patients with breast cancer after surgery. Objective: : The purpose of this systematic review and meta-analysis was to examine the effect of massage therapy on post-surgical pain and anxiety in patients with breast cancer. Methods: Systematic searches were performed using databases PubMed, CINAHL, and Medline (EBSCO), with no date constraint through September 30, 2023, to identify randomized control trials, randomized pilot, and quasi-experimental studies. The database searches retrieved 1205 titles, and after screening, 7 studies were chosen for full analysis using Cohen's d, 95% Confidence Interval (CI), and effect size. The heterogeneity of the studies was calculated in the meta-analysis using Cochran's Q equation. Results: Massage therapy techniques reported were massage therapy, classic massage, reflexology, myofascial release, and myofascial therapy, and were performed at day 0 up to 16 weeks post-surgery. Massage therapy decreased pain and anxiety for patients in the massage group. Analyses showed a positive effect size using massage therapy as an intervention for pain and anxiety in women with breast cancer post-surgery. Overall effect size for pain was 1.057 with a P-value of <.0001, and overall effect size for anxiety was .673 with a P-value of <.0001. Conclusion: The current evidence in this study reflects that massage therapy is effective as a non-pharmacological tool in decreasing post-surgical pain and anxiety in women with breast cancer.

Massage as a Mechanotherapy for Skeletal Muscle.

Massage is anecdotally associated with many health benefits, but physiological and clinically relevant mechanisms recently have begun to be investigated in a controlled manner. Herein, we describe research supporting our hypothesis that massage can be used as a mechanotherapy imparting biologically relevant adaptations in skeletal muscle and improving muscle properties.

Physical Therapy Management of an Individual With Post-COVID Syndrome: A Case Report.

OBJECTIVE: The purpose of this case report is to provide the clinical presentation and physical therapist management for a patient with post-COVID syndrome. Secondarily, the report highlights the importance of assessing cognitive and emotional health in patients with post-COVID syndrome. METHODS (CASE DESCRIPTION): A 37-year-old woman tested positive for SARS-CoV-2 and developed mild COVID-19 disease but did not require supplemental oxygen or hospitalization. The patient experienced persistent symptoms, including dyspnea, headaches, and cognitive fog. On day 62, they participated in an outpatient physical therapist evaluation that revealed deficits in exercise capacity, obtaining 50% of their age-predicted 6-minute walk distance. They had minor reductions in muscle strength and cognitive function. Self-reported quality of life was 50, and they scored above established cut-off scores for provisional diagnosis of posttraumatic stress disorder (PTSD). RESULTS: The patient participated in biweekly physical therapist sessions for 8 weeks, which included aerobic training, strengthening exercises, diaphragmatic breathing techniques, and mindfulness training. Metabolic equivalent for task levels increased with variability over the course of the program. The patient's muscle strength, physical function, and exercise capacity improved. 6-Minute walk distance increased by 199 m, equating to 80% of their age-predicted distance. Quality of life and PTSD scores did not improve. At evaluation after physical therapy, the patient was still experiencing migraines, dyspnea, fatigue, and cognitive dysfunction. CONCLUSION: This case report described the clinical presentation and physical therapist management of a person with post-COVID syndrome, a novel health condition for which little evidence exists to guide rehabilitation examination and interventions. Physical therapists should consider cognitive function and emotional health in their plan of care for patients with post-COVID syndromes. IMPACT: This case alerts physical therapists to post-COVID syndrome-which can include debilitating symptoms of decreased aerobic tolerance, anxiety, PTSD, and cognitive dysfunction-and to the role that therapists can play in assessing these symptoms and managing these patients.

Massage as a mechanotherapy promotes skeletal muscle protein and ribosomal turnover but does not mitigate muscle atrophy during disuse in adult rats.

AIM: Interventions that decrease atrophy during disuse are desperately needed to maintain muscle mass. We recently found that massage as a mechanotherapy can improve muscle regrowth following disuse atrophy. Therefore, we aimed to determine if massage has similar anabolic effects when applied during normal weight bearing conditions (WB) or during atrophy induced by hindlimb suspension (HS) in adult rats. METHODS: Adult (10 months) male Fischer344-Brown Norway rats underwent either hindlimb suspension (HS, n = 8) or normal WB (WB, n = 8) for 7 days. Massage was applied using cyclic compressive loading (CCL) in WB (WBM, n = 9) or HS rats (HSM, n = 9) and included four 30-minute bouts of CCL applied to gastrocnemius muscle every other day. RESULTS: Massage had no effect on any anabolic parameter measured under WB conditions (WBM). In contrast, massage during HS (HSM) stimulated protein turnover, but did not mitigate muscle atrophy. Atrophy from HS was caused by both lowered protein synthesis and higher degradation. HS and HSM had lowered total RNA compared with WB and this was the result of significantly higher ribosome degradation in HS that was attenuated in HSM, without differences in ribosomal biogenesis. Also, massage increased protein turnover in the non-massaged contralateral limb during HS. Finally, we determined that total RNA degradation primarily dictates loss of muscle ribosomal content during disuse atrophy. CONCLUSION: We conclude that massage is an effective mechanotherapy to impact protein turnover during muscle disuse in both the massaged and non-massaged contralateral muscle, but it does not attenuate the loss of muscle mass.

Massage increases satellite cell number independent of the age-associated alterations in sarcolemma permeability.

Massage is a widely accepted manual therapy used to modulate the inflammatory response of muscle and restore function, but prolonged compression of muscle potentially causes overt injury and damage to muscle fibers. Therefore, a balance exists between the positive effects of massage and the induction of mechanical damage and injury. In addition, skeletal muscle of aged individuals displays increased stiffness, and therefore, the response to massage is likely different compared with young. We hypothesized that the aged skeletal muscle exhibits increased sarcolemmal permeability when subjected to massage compared with young skeletal muscle. Male Brown Norway/F344 rats, 10 and 30 months of age, were each divided into control, non-massaged (n = 8) and massaged (n = 8) groups. The right gastrocnemius muscle received one bout of cyclic compressive loading for 30 min at 4.5 N as a massage-mimetic. Muscles were dissected and frozen 24 h after massage. Alterations in sarcolemma permeability were quantified by measuring the level of intracellular IgG within the muscle fibers. Immunohistochemistry was performed to determine IgG inside fibers and Pax7+ cell number as an indicator of stem cell abundance. Average IgG intensity was not different between control and massaged animals at either age. However, a significant shift to the right of the density histogram indicated that massaged animals had more fibers with higher IgG intensity than control at 10 months. In addition, Pax7+ cell number was significantly elevated in massaged muscles compared with control at both ages. One bout of massage did not induce overt muscle injury, but facilitated membrane permeability, which was associated with an increase in satellite cell number. Data suggest that the load applied here, which was previously shown to induce immunomodulatory changes, does not induce overt muscle injury in young and old muscles but may result in muscle remodeling.

Enhanced skeletal muscle regrowth and remodelling in massaged and contralateral non-massaged hindlimb.

KEY POINTS: Muscle fibre cross sectional area is enhanced with massage in the form of cyclic compressive loading during regrowth after atrophy. Massage enhances protein synthesis of the myofibrillar and cytosolic, but not the mitochondrial fraction, in muscle during regrowth. Focal adhesion kinase activation and satellite cell number are elevated in muscles undergoing massage during regrowth. Muscle fibre cross sectional area and protein synthesis of the myofibrillar fraction, but not DNA synthesis, are elevated in muscle of the contralateral non-massaged limb. Massage in the form of cyclic compressive loading is a potential anabolic intervention during muscle regrowth after atrophy. ABSTRACT: Massage, in the form of cyclic compressive loading (CCL), is associated with multiple health benefits, but its potential anabolic effect on atrophied muscle has not been investigated. We hypothesized that the mechanical activity associated with CCL induces an anabolic effect in skeletal muscle undergoing regrowth after a period of atrophy. Fischer-Brown Norway rats at 10 months of age were hindlimb unloaded for a period of 2 weeks. The rats were then allowed reambulation with CCL applied at a 4.5 N load at 0.5 Hz frequency for 30 min every other day for four bouts during a regrowth period of 8 days. Muscle fibre cross sectional area was enhanced by 18% with massage during regrowth compared to reloading alone, and this was accompanied by elevated myofibrillar and cytosolic protein as well as DNA synthesis. Focal adhesion kinase phosphorylation indicated that CCL increased mechanical stimulation, while a higher number of Pax7+ cells likely explains the elevated DNA synthesis. Surprisingly, the contralateral non-massaged limb exhibited a comparable 17% higher muscle fibre size compared to reloading alone, and myofibrillar protein synthesis, but not DNA synthesis, was also elevated. We conclude that massage in the form of CCL induces an anabolic response in muscles regrowing after an atrophy-inducing event. We suggest that massage can be used as an intervention to aid in the regrowth of muscle lost during immobilization.

Investigating the mechanisms of massage efficacy: the role of mechanical immunomodulation.

Massage has the potential to attenuate the inflammatory process, facilitate early recovery, and provide pain relief from muscular injuries. In this hypothesis-driven paper, we integrate the concept of mechanotransduction with the application of massage to explore beneficial mechanisms. By altering signaling pathways involved with the inflammatory process, massage may decrease secondary injury, nerve sensitization, and collateral sprouting, resulting in increased recovery from damage and reduction or prevention of pain. Our goal is to provide a framework that describes our current understanding of the mechanisms whereby massage therapy activates potentially beneficial immunomodulatory pathways.

Immunomodulatory effects of massage on nonperturbed skeletal muscle in rats.

Massage is an ancient manual therapy widely utilized by individuals seeking relief from various musculoskeletal maladies. Despite its popularity, the majority of evidence associated with massage benefits is anecdotal. Recent investigations have uncovered physiological evidence supporting its beneficial use following muscle injury; however, the effects of massage on healthy, unperturbed skeletal muscle are unknown. Utilizing a custom-fabricated massage mimetic device, the purpose of this investigation was to elucidate the effects of various loading magnitudes on healthy skeletal muscle with particular interest in the gene expression profile and modulation of key immune cells involved in the inflammatory response. Twenty-four male Wistar rats (200 g) were subjected to cyclic compressive loading (CCL) over the right tibialis anterior muscle for 30 min, once a day, for 4 consecutive days using four loading conditions: control (0N), low load (1.4N), moderate load (4.5N), and high load (11N). Microarray analysis showed that genes involved with the immune response were the most significantly affected by application of CCL. Load-dependent changes in cellular abundance were seen in the CCL limb for CD68(+) cells, CD163(+) cells, and CD43(+)cells. Surprisingly, load-independent changes were also discovered in the non-CCL contralateral limb, suggesting a systemic response. These results show that massage in the form of CCL exerts an immunomodulatory response to uninjured skeletal muscle, which is dependent upon the applied load.
