Changes in Spine Alignment and Postural Balance After Breast Cancer Surgery: A Rehabilitative Point of View

Biofeedback-Based Proprioceptive Training to Improve Functional Prerequisites of Dragon Boating in Breast Cancer Survivors

Breast cancer (BC)-related sequelae drastically impact the psychophysical functioning and quality of life of affected women. Adapted physical activity (APA) has proved to effectively counteract these impairments in a non-medicalized framework. In particular, dragon boats are able to promote body functionality, social interaction, and quality of life in BC survivors, but the literature on specific motor gestures is scarce and practice is still based more on a re-educative perspective than a performative one. In this context, the present longitudinal study investigated the benefits of an adapted biofeedback-based sensorimotor training intervention on upper body functionality in a team of dragon ladies. The 8-week intervention was conceived as integrated dry workout sessions led by an APA kinesiologist and applied a novel sensorized proprioceptive device, such as a Libra board. Post-protocol evaluation revealed a significant improvement in bilateral upper limb mobility, core endurance, and trunk stability along with a distress decrease and quality of life enhancement through validated assessment tools. Our findings suggest that integrating biofeedback-based workout sessions can effectively promote upper body functionality in BC survivors practicing dragon boating. Furthermore, our innovative approach could help spread methodological hints able to boost exercise adherence in this target population, thus counteracting cancer recurrence while promoting overall well-being.

Occupational Therapy After Breast Cancer Reconstructive Surgery: A Predictor for Opioid Prescriptions

Occupational therapy practitioners have a unique and vital role among interprofessional health care teams toward facilitating occupational participation among breast cancer survivors. This study investigated the relationship between acute medicine occupational therapy services after breast cancer reconstructive surgeries (BCRS) and a number of prescription refills 90 days after surgery. This retrospective study ran binary logistic regression analyses on 562 women after BCRS for refills of opioid and non-opioid medication. Both models were statistically significant, χ2(7df) = 23.001, p = .002; χ2(7df) = 32.312, p < .001, indicating the ability to distinguish who received opioid or non-opioid refills, respectively. While younger age was a significant predictor across both models, occupational therapy was only significant for opioid refills; each was associated with fewer refills. Early occupational therapy treatment after BCRS is associated with fewer opioid prescriptions 90 days after surgery, therefore enhancing occupation throughout this timeframe is beneficial.

Impact of unilateral mastectomy on body posture: A prospective longitudinal observational study

Objective

Unilateral mastectomy is known to induce postural alterations, yet the temporal development pattern of these changes remains elusive. This study aimed to explore the impact of unilateral mastectomy on body posture.

Methods

A prospective, longitudinal, observational study with a one-group repeated-measures design was conducted. Patients undergoing unilateral mastectomy were recruited from a university-affiliated hospital in Western China and monitored for 12 months post-surgery. A trained nurse assessed seven postural baseline parameters on the day of suture removal and at 3, 6, and 12 months after unilateral mastectomy. Two parameters were in the sagittal plane (forward head posture and trunk rotation angle), and five were in the coronal plane (neck tilt, shoulder asymmetry, scapular asymmetry, scapular asymmetry relative to the spine, and pelvic tilt).

Results

The final analysis included 159 patients. Baseline prevalence of most postural abnormalities ranged from 50.94% to 59.75%, with mean deviations between 2.74 and 4.51 mm. At 12 months post-mastectomy, prevalence and mean deviations increased by more than 30% and 3.50 mm, respectively, compared to baseline. Postural abnormalities increased gradually in the first 3 months, notably between the 3rd and 6th months, and slowed between the 6th and 12th months. On the mastectomy side, coronal plane abnormalities significantly increased within 12 months: earlobe to acromion distance (Wald χ2 = 45.283, P < 0.001), depressed shoulder height (Wald χ2 = 42.253, P < 0.001), depressed scapula height (Wald χ2 = 31.587, P < 0.001), scapula to spine distance (Wald χ2 = 45.283, P < 0.001), and elevated pelvic height (Wald χ2 = 48.924, P < 0.001).

Conclusions

Postural changes are common post-unilateral mastectomy, with prevalence and deviation increasing gradually, particularly between 3 and 6 months post-mastectomy. Early rehabilitation initiation is recommended to mitigate postural changes.

Effects of the Anchor System on Postural Balance of Women Undergoing Breast Cancer Treatment: A Clinical, Randomized, Controlled, and Crossover Trial

OBJECTIVE

Investigate the effects of multisensory training with and without the anchor system on breast cancer survivors' postural balance and self-efficacy of falls.

DESIGN

Clinical randomized, controlled, and crossover trial.

SETTING

Teaching, Research, and Assistance Center in Mastectomized Rehabilitation.

PARTICIPANTS

Eighty breast cancer survivors homogeneously distributed in the groups of adults and elderly affected, or not, by lymphedema.

INTERVENTIONS

Participants were randomized to multisensory training with and without the anchor system involving 3 sessions per week for 12 weeks. After the 4-week washout period, the remaining therapeutic intervention was applied.

MAIN OUTCOME MEASURES

The primary outcome was semi-static and dynamic balance as evaluated by baropodometry and Mini Balance Evaluation Systems Test, and the secondary outcome was self-efficacy of the fall episode as assessed by Falls Efficacy Scale - International in the pre-, post-immediate, and 4-week follow-up period.

RESULTS

Both therapeutic interventions caused positive and significant effects on postural balance and self-efficacy of falls in the immediate period. The multisensory training with the anchor system induced significant functional retention in the short term, related to the clinical effect of small to moderate variation.

CONCLUSIONS

Multisensory training with the anchor system is convenient for postural balance and self-efficacy for falls, regardless of age and upper limb volume, for breast cancer survivors.

Back geometry and mobility function changes in cerebral palsy children after backward walking training: arandomized controlled trial

AIM

To compare the effects of backward (BW) and forward (FW) walking training on back geometry and mobility function in children with hemiparetic cerebral palsy (CP).

METHODS

Fifty-five children with hemiparetic CP participated in this study. They were randomly assigned into two groups. For 12 weeks, both groups got a conventional physical therapy program three days/week. Groups A and B got a specifically developed FW walking training (25 minutes/session) and a specially designed BW walking training (25 minutes/session), respectively.

RESULTS

The trunk imbalance, lateral deviation, pelvic tilting, pelvic torsion, surface motion, and dynamic gait index of group B improved significantly more than group A (p < .05). Both groups showed significant improvements in all measured variables (p < .05).

CONCLUSION

BW walking training might be considered as an effective therapy modality for improving back geometry and mobility function in hemiparetic CP children compared with FW walking training combined with a typical program.

Static and Dynamic Imbalance in Patients with Breast Cancer-Related Lymphedema

Background: Breast cancer-related lymphedema (BCRL) was associated with postural imbalance, but the immature knowledge introduced debate about which component of the balance was affected by BCRL in the literature. The aim of this study was to determine the static and dynamic balance of patients with BCRL in comparison with healthy subjects. Methods and Results: This case-control designed study recruited 30 BCRL patients and 30 healthy individuals. The demographic and clinical variables of the subjects were recorded. The static balance stability parameters on four conditions (eyes opened-stable ground, eyes closed-stable ground, eyes opened-unstable ground, eyes closed-unstable ground) and dynamic stability of all participants were evaluated. The values of both stable ground conditions were similar between the groups (p < 0.05). However, values of both eyes opened-unstable ground (p = 0.032) and eyes closed-unstable ground (p = 0.034) conditions were significantly impaired in BCRL in comparison with controls. Besides, comparison of sway area of the opened versus closed eyes conditions on unstable ground (p = 0.036), and movement speed while correcting the center of pressure on unstable ground (with opened and closed eyes, p = 0.014 and p = 0.004 respectively) revealed increased values in the BCRL group. Likewise, the dynamic stability was significantly disrupted in the BCRL group (p = 0.043). Conclusion: Closing eyes did not affect the postural balance in patients with BCRL, whereas the deterioration of ground altered the balance significantly in the BCRL group compared with healthy subjects. We suggest the inclusion of balance exercises and guidance for selection of correct shoes and insoles in routine lymphedema rehabilitation program.

Postural Analysis Using Rasterstereography and Inertial Measurement Units in Volleyball Players: Different Roles as Indicators of Injury Predisposition

Background and Objectives: Acute and chronic injuries are frequent in volleyball. Biomechanics of sport-specific tasks can influence the risk of injury, which is also related to specific court positions. We investigated posture at raster-stereography, balance, and dynamic tasks using inertial motion units to find differences between roles, which can be predictive of a higher risk of injury. Materials and Methods: We cross-sectionally evaluated amateur volleyball athletes. Participants were divided into roles as outside hitters, setters, middle blockers, and opposite hitters. We excluded the "libero" position from our analysis. Results: Sixteen players were included in the analysis. A statistically significant difference was found in left lower limb stiffness among the outside hitter and setter groups. Conclusions: Differences in stiffness might be related to the different training and the different abilities among the two groups. Raster-stereography is extending its indications and should be implemented for non-invasive postural analysis. The use of inertial motion units provides objective measurements of variables that could go unrecognized within a clinical evaluation; its use should be considered in injury preventive programs.

Investigation of the relationship between spinal posture and mobility to respiratory muscle strength and pulmonary functions in unilateral breast cancer surgery survivors: a cross-sectional study

PURPOSE

Despite the research on structural and functional changes that may occur in breast cancer survivors, no study has investigated the relationship between spinal characteristics and the respiratory system. Therefore, we aimed to investigate the relationship between spinal posture and mobility to respiratory muscle strength and pulmonary functions in breast cancer patients who have completed their treatment METHODS: This cross-sectional study included 38 female breast cancer surgery survivors. Participants underwent the following evaluations: Chest wall mobility with a tapeline; postural assessments (spinal curvature, spinal mobility, and spinal inclination) with a non-invasive, computer-assisted electromechanical device; and pulmonary function test and respiratory muscle strength with a portable digital spirometer device. The relationship between spinal posture and mobility to respiratory muscle strength and pulmonary functions was analyzed by the bivariate correlation analysis.

RESULTS

Increased thoracic curvature angle was associated with decreased FEV1 (r=-0.360, p=0.026) and decreased subcostal mobility (r=-0.385, p=0.017), and the increase in thoracic frontal mobility was associated with decrease in PEF (r=-0.342, p=0.036). Increased lumbar mobility was associated with increased FVC (r=0.324, p=0.047), and increased total spinal inclination mobility was associated with decreased MIP (r=-0.396, p=0.017). Chest wall mobility was associated with postural assessments at varying rates (the r value ranged from -0.357 to 0.661, p<0.05).

CONCLUSION

The changes in spinal posture and mobility of women who have undergone unilateral breast cancer surgery were associated with respiratory parameters and thoracic cage mobility. These patients' spinal posture and mobility should be taken into account in conjunction with respiratory functions for a comprehensive assessment.

The Influence of External Breast Prostheses on the Body Postures of Women Who Have Undergone Mastectomies

Most women who have had a mastectomy and have not opted for breast reconstruction choose to use an external breast prosthesis. This study aimed to assess the impacts of external breast prostheses on the body postures of women after unilateral mastectomies. An additional aim was to identify whether postural asymmetry depended on the side of mastectomy. This study involved 52 women after unilateral mastectomy and consisted of two parts: (1) anthropometric measurement and (2) assessment of body posture using the moiré topography method. The posturometric indices showed that the body posture of the subjects in the sagittal plane is characterized by forward trunk inclination and a tendency to excessive kyphosis. There were no significant differences between parameters characterizing body posture with and without external breast prosthesis. The lack of external breast prosthesis had a significant effect only on excessive forward trunk inclination. Significant differences were found in the posturometric parameters in the transverse plane between the groups of patients after left- and right-sided mastectomy. The obtained results did not fully confirm the hypothesis that the external breast prosthesis affects the body posture of women after unilateral mastectomy.

The effect of complex decongestive therapy on spatio-temporal parameters and balance in women with breast cancer-related upper extremity unilateral lymphedema

BACKGROUND

The aim of this study was to investigate the effect of complex decongestive therapy on spatio-temporal parameters and balance in individuals with breast cancer-related upper extremity unilateral lymphedema.

METHODS

The study was designed as a prospective, cross-sectional study. Thirty sessions of complex decongestive therapy were applied. Participants' pre-and post-treatment spatio-temporal parameters and balance parameters were evaluated with the Win Track platform. In addition, the Timed Up and Go test was used to evaluate the dynamic balance. Plethysmography, a water displacement method, was used to measure upper extremity volume.

FINDINGS

Significant improvement was observed in limb volume asymmetry after complex decongestive therapy. While the stride length of the affected side was 409.93 mm before the treatment, it increased to 500.93 mm after the treatment, and a significant increase was observed (p = 001). Significant improvements were found in the other spatio-temporal parameters of the participants. Compared to the pre-treatment, a significant decrease was detected in the average cadence value, Timed Up and Go value, double stance time, and maximum plantar pressure point of the participants. Significant improvements were found in the participants' balance.

INTERPRETATION

Complex decongestive therapy applied to individuals with unilateral upper extremity lymphedema provides significant improvement in both spatio-temporal and balance parameters. However, we recommend complex decongestive therapy as an effective and safe treatment to reduce the volume of lymphedema. Patients with unilateral lymphedema that may cause postural asymmetry should be informed about balance and gait disturbance and should be encouraged to receive lymphedema treatment as soon as possible.

“Hook Shape” Nipple-Sparing Mastectomy and Prepectoral Implant Reconstruction: Technique, Results and Outcomes from a Preliminary Case Series

INTRODUCTION

Nipple-sparing mastectomy (NSM) is a surgical procedure increasingly performed for breast cancer or risk reduction surgeries. The site of skin incision seems to affect not only cosmesis but also technical ease in operating and vascular viability of the nipple. We present a series of patients who underwent a modified vertical surgical approach for NSM, which resulted to be safe, reliable, and with good esthetic results.

MATERIALS AND METHODS

From December 2016 to February 2019, 27 "Hook Shape" incision NSMs were performed. All patients underwent an immediate subcutaneous muscle-sparing reconstruction with tissue expander covered by a titanium-coated polypropylene mesh, followed by a second surgical step with expander substitution and lipofilling on the definitive implant when indicated. Preoperative and postoperative BREAST-Q patient-reported outcomes measure was performed in all cases.

RESULTS

Postoperative morbidity was evaluated: One patient developed seroma and another presented a systemic infection that resolved with intravenous infusion of antibiotics. One patient experienced vertical wound dehiscence, recovered after conservative treatment and without implant exposure. No implant loss was observed. Nipple-areola complex necrosis or ischemia rate was 0%. The BREAST-Q outcomes reported significant increases in the overall satisfaction with breast (p < 0.05), psychosocial well-being (p < 0.05), and sexual well-being (p < 0.05) sections. Scores in the physical impact of surgery section appeared to decline from preoperative to postoperative evaluations, with no statistically significant results.

CONCLUSION

The mastectomy incision pattern can burden the surgical challenge, impact vascular viability of the nipple and significantly affect the aesthetic outcomes in breast reconstruction. We report our experience with an alternative approach for NSM, which appears a safe, practical, and reproducible method for patients with small- to medium-sized breasts and little/medium ptosis (grade I or II).

Influence of the external breast prosthesis on the postural control of women who underwent mastectomy: Cross-sectional study

Women after mastectomy may decide to either have a breast reconstruction or use an external breast prosthesis. Aim: The aim of the presented research was to evaluate the influence of external breast prosthesis on postural stability in women after mastectomy. Methods and Procedures: In the study 52 women after unilateral mastectomy took part. The study consisted of 4 parts: 1) anthropometric measurements; 2) measurements of upper limb circumference; 3) assessment of weight-bearing (WB); and 4) posturographic tests (PT). Outcomes and Results: Differences in the arm circumferences on the amputated (A) and non-amputated (NA) sides did not confirm the occurrence of lymphedema in limb on amputated side. The results of the WB between the A and NA body sides in both tested conditions, i.e., with open and closed eyes, showed no significant differences between the test with and without an external prosthesis. No statistically differences have been observed between posturometric parameters with and without breast prosthesis during both PT. In comparing the posturometric parameters between the PT with open and closed eyes, the sway path of the center of pressure was statistically significantly longer when eyes were closed in both conditions, i.e., with and without breast prosthesis. Conclusion and Implications: The finding show that 1) external breast prosthesis does not have a significant influence on the symmetry of loading on the A and NA body sides and on the postural stability of women after unilateral mastectomy and 2) exclusion visual control during PT increases postural instability in women after unilateral mastectomy.

The effect of upper limb lymphedema in posture of patients after breast cancer surgery

BACKGROUND

Upper limb lymphedema is one of the complications following breast cancer-related surgery. It is a fact that there are alterations in posture of the trunk following surgery, however, there is not much data on whether upper limb lymphedema has any effect on body posture.

OBJECTIVES

The main purpose of the study was to investigate the effect of upper limb lymphedema in the trunk posture and spine mobility of patients following breast cancer surgery.

METHODS

Twenty-seven women with lymphedema and 29 women without lymphedema with mastectomy or breast-conserving surgery participated in the study. Posture was evaluated by the New York Posture Rating Chart and spinal stability and thoracic mobility were evaluated by the Spinal Mouse device.

RESULTS

Posture and spine posture scores were significantly higher in the without lymphedema group (p= 0.004; 0.041; respectively). There was a significant difference between the groups in terms of lateral (p< 0.001) and posterior (p< 0.001) view of shoulders, spine (p= 0.027), upper (p< 0.001) and lower back (p= 0.009), and trunk postures (p= 0.001).

CONCLUSIONS

Body posture and spine are more affected due to upper limb lymphedema following breast cancer surgery. Alterations of posture mainly occur on shoulders, spine, upper and lower back, and trunk, but not on head and neck postures.

A comprehensive approach to risk factors for upper arm morbidities following breast cancer treatment: a prospective study

BACKGROUND

Breast cancer surgery frequently causes deficiencies in shoulder functioning. The study pourpode is to identify risk factors for prolonged pain, reduction in function, and decrease in range of motion (ROM) in BC patients.

METHODS

A prospective cohort study was designed in a private hospital; between October 2018 and April 2019 with a follow-up of 6 months. Patients following BC surgery, were divided by arm morbidities, and the different risk facrors were evaluated using univariate analysis and logistic regression.

RESULTS

A total of 157 patients were included in the study. Risk factors for functional disabilities included; pain levels during hospitalization NPRS 1.2 (±0.8) compared to patients with no disabilities 0.5 ± 0.7 (p = .006), the size of tumors more than 1.4 ± 0.8 cm. compared with no morbidities 0.8 ± 0.9 cm. (p = .046), and breast reconstructions (p = .030). Risk factors for prolonged pain includes mastectomy (p = .006), breast reconstruction (p = .011), more than three dissected lymph nodes (p = .002), the presence of preoperative pain (p < .001), in-hospital pain (p < .001), axillary web syndrome (p < .001) and lymphedema (p < .001). Risk factors for decreased ROM were more than three dissected lymph nodes (p = .027), radiation (p = .018), and the size of dissected tissue (p = .035). Postoperative physical therapy appears to reduce the incidence of prolonged pain (p = .013) and regular physical activity may reduce long term functional disabilities (p = .021).

CONCLUSIONS

Upper arm morbidity following BC treatments affect up to 70% of the patients. Identifying the different risk and beneficial factors may improve awareness among physicians to refer patients to early rehabilitation programs and thus avoid chronic morbidity and improve the course of recovery.

TRIAL REGISTRATION

The study was registered in Clinical trial with the ID number: NCT03389204 .

"Just Pulse it!" Introduction of a conservative implant salvage protocol to manage infection in pre-pectoral breast reconstruction: Case series and literature review

Post-operative implant infection is generally rare after breast augmentation, but it can occur in up to 35% of cases in post-mastectomy breast reconstruction. Standard treatment consists in the administration of antibiotics, implant removal, and delayed prosthesis replacement leading to multiple operations, with a negative impact on patient's clinical, economical, and psychological outcomes. There is little information published in the literature on the management of periprosthetic infection following pre-pectoral reconstructions. Capsule's removal from a pre-pectoral plane brings the risk of excessive tissue thinning and the compromise of skin flaps viability. In this preliminary multi-center case series, eight patients diagnosed with implant infection following oncological mastectomy and two-stage heterologous pre-pectoral breast reconstruction underwent the same protocol, consisting in tissue expander removal and conservative surgical revision supplemented by an antibiotate pulse lavage of the pocket surface. All patients achieved a successful infection resolution with immediate prosthesis replacement switching the temporary expander to definitive implant. No additional surgical revision was registered during follow-up. The intermittent irrigation is meant to disrupt the biofilm structure and restore antibiotic susceptibility. Moreover, pulse lavage allows the cleansing of the prosthetic capsule, thus avoiding the vascular stress associated with subcutaneous capsulectomy. To the best of our knowledge, this is the first series reporting on the use of Pulsavac in periprosthetic infection following pre-pectoral breast reconstruction, in an attempt to set the basis for an alternative conservative protocol to manage breast implant infection. A thorough literature review on pulse lavage in breast surgery was carried out.

The effects of post-mastectomy lymphedema on balance, Kinesiophobia and fear of falling

The purpose of this study is to investigate the effects of post-mastectomy lymphedema on balance, kinesiophobia and fear of falling. A cross-sectional study with a control group. Seventy patients and 62 healthy volunteers were included. After determining the stage and limb volumes of the patients, all participants were evaluated with scales. There was a statistically significant difference in all scales compared to the control group (p < .001). There was a correlation between the stage of lymphedema and limb volume difference, balance, kinesiophobia, fear of falling (p < .001). In proportion with its stage and severity, lymphedema causes balance disorder, kinesiophobia and fear of falling.

The Influence of Rehabilitation on Quality of Life in Breast Cancer Survivors: A Clinical Study

Background: Breast cancer survivors report negative impacts of cancer, augmented by specific vulnerabilities to body changes, negative self-assessment, and quality-of-life concerns. The main objective of our work was to test the effect of a rehabilitation program on breast cancer patients by evaluating the change in their physical well-being during an outpatient rehabilitation setting and, subsequently, in a home rehabilitation setting, considering the individual personality profile. Methods: Patients who underwent total mastectomy with breast prostheses or tissue expanders were enrolled. Outcome assessments (Pain, Quality of Life, Personality traits for the Minnesota Multiphasic Personality Inventory-2) before treatment (T0), at the end of the rehabilitative treatment (T1 = 10 sessions 2/week, one hour/each), and after two months of follow-up (T2) were performed. Results: The data of 38 included patients were analyzed. The quadratic trend of the Visual Analogue Scale can be explained by the fact that patients have a strong reduction in the perceived pain immediately after rehabilitation in the clinic. This reduction remains constant for the home period of the rehabilitation. The personality profiles of all the participants were substantially valid. Only three patients obtained scores higher than 65 points. Conclusions: The study evidenced that in the initial phase of the rehabilitation, psychological traits such as anxiety, depression, and preoccupation could have a strong association especially with the autonomous functions and the perceived physical symptoms. However, during the therapeutic process, this association decreased and these decrements were higher when patients performed their rehabilitation at home, in a more familiar and comfortable setting.

Rehabilitation interventions to support return to work for women with breast cancer: a systematic review and meta-analysis

Background

Research recommends the development and evaluation of interventions to support women with breast cancer in returning to, or managing, work. Despite this, there has historically been a paucity of rehabilitation interventions to support women with breast cancer to maintain or return to their work role. The aim of this systematic review was to examine key characteristics of rehabilitation interventions, and their effectiveness on work outcomes for women with breast cancer, compared to usual care.

Methods

A systematic review was conducted of controlled studies of rehabilitation interventions with work outcomes for women with breast cancer. Six databases were systematically searched: EMBASE, Web of Science, MEDLINE (OVID), CINAHL, PsycINFO, and the Cochrane Central Register of Controlled Trials (CENTRAL). Results are presented either as pooled odds ratio (OR) or pooled effect size (hedges g) between groups, with 95% confidence intervals (CI). Narrative synthesis was conducted on intervention outcomes not suitable for meta-analysis.

Results

Five thousand, five hundred and thirty-five studies were identified. Nine out of 28 abstracts met inclusion criteria. Heterogeneity of interventions and outcomes precluded meta-analysis for most outcomes. Of the interventions included in meta-analysis, no significant differences compared to usual care were found for sick leave (2 studies (12 months); OR 1.11 (95% CI: 0.66 to 1.87), number of sick days taken (2 studies (six months); difference in effect: − 0.08, (95% CI: − 0.48 to 0.38) or working hours (2 studies (12 months); 0.19, (95% CI: − 0.20 to 0.64). Only one study, with a multidisciplinary intervention, showed a significant difference for work outcomes when compared to usual care. Work-specific content featured in three interventions only, none of which provided conclusive evidence for improvement in work outcomes. Enhanced physical and psychological sequalae, and quality of life was observed in some studies.

Conclusion

There remains a lack of effective and methodologically rigorous rehabilitation intervention studies for breast cancer survivors. The development and evaluation of effective rehabilitation interventions to support return to work is warranted.

Muscle Energy Technique in the Rehabilitative Treatment for Acute and Chronic Non-Specific Neck Pain: A Systematic Review

Background: Non-specific neck pain (NNP) affects 30–50% of the general population, and it often leads to severe disability. Several manual therapy techniques are available to reduce pain and disability and to improve cervical range of motion and functional activities. Muscle Energy Technique (MET) showed more evidence for treating such a disorder. The aim of this current scientific literature analysis was to compare the clinical effects of MET with the other manual or rehabilitative treatments for non-specific acute and chronic neck pain. Methods: The literature search was conducted using the following databases: PubMed, Medline, PEDro, Cochrane Database, and Google Scholar from 2010 to January 2020. Clinical trials about MET were included. The quality of the trials was assessed according to the PEDro scale. Results: Twenty-one papers according to inclusion and exclusion criteria were selected: 15 studies about non-specific acute neck pain and 6 studies about non-specific chronic neck pain. Conclusions: This analysis suggests that the MET approach has a good clinical effect on reducing neck pain in patients with acute neck pain and improves cervical range of motion in patients with chronic neck pain, and is better if combined with a traditional rehabilitative approach. This review’s findings should be considered with caution for physiotherapy practice because of the studies’ methodologic limitations. On the basis of the current available and limited evidence, clinicians could combine MET with traditional physiotherapy and other manual techniques when treating people with non-specific neck pain.

Mat pilates method improve postural alignment women undergoing hormone therapy adjunct to breast cancer treatment. Clinical trial

The purpose of the study is to analyze the effects of a mat Pilates intervention on the postural alignment and balance of breast cancer women receiving hormone therapy. A two-arm randomized clinical trial included 34 breast cancer survivors divided randomly between a mat Pilates group (n = 18), that performed 16 weeks of mat Pilates exercises, and a control group (n = 16), who were invited to maintain their daily routine activities and received three educational sessions. Data collection occurred at baseline and at post-intervention time. The postural alignment was assessed using the Postural Assessment Software (SAPO) and the balance was assessed by the MINIBESTest. When the two-way ANOVA was performed on postural alignment results, a significant statistical difference was found in the angle between acromions and the anterior-superior iliac spines of the mat Pilates group (p = 0.036). When compared to the post-intervention period, the mat Pilates method had an improved horizontal alignment of the anterior-superior iliac spines (p = 0.039) and vertical alignment of the acromion head on the right side (p = 0,016). Also, the participants of the Pilates group showed a significant statistical difference in the balance (p = 0.034). The control group had an improved vertical trunk alignment on the left side (p = 0,048). The control group and the mat Pilates method group improved in some aspects, however the mat Pilates method was effective in improving the postural alignment and the balance of breast cancer survivors receiving hormone therapy and may be recommended in oncological rehabilitation as a type of complementary therapy.

Analysis of Spinal Dysfunction in Breast Cancer Survivors with Lymphedema

Background:

To study and analyse the spinal dysfunction in breast cancer survivors with lymphedema.

Methods:

This study was carried out by analysing total 116 breast cancer survivor women, who were having lymphedema. Out of 116 subjects, 39 undergone radical mastectomy (RM), 39 undergone modified radical mastectomy (MRM) and 38 undergone breast conserving surgery (BCS). Thesesubjects were assessed for spinal function bytaking range of motionusing goniometer, lymphedema measurement usinginch tape, spinal stability test and functional rating index.

Results:

The spinal range of motion wassignificantly reduced in patients suffering from lymphedema in breast cancer survivors. The strength and endurance were significantly reduced in abdominals, extensors and lateral muscles of spine. There wasmarked effect seen on quality of life of patients assessed by using functional rating index due to spinal dysfunction in lymphedema patients.

Conclusion:

This study showed that there is statistically significant spinal dysfunction caused due to lymphedema in breast cancer survivors.

The Influence of Nordic Walking on Isokinetic Trunk Muscle Endurance and Sagittal Spinal Curvatures in Women after Breast Cancer Treatment: Age-Specific Indicators

Nordic walking (NW) is a popular form of rehabilitation. NW improves psychophysical condition in breast cancer (BC) survivors. This study aimed to analyze the effects of NW on functional and postural changes of the trunk in women of different ages after BC. We hypothesized that an age relationship would be found. BC survivors (n = 39) were stratified by age as “middle- aged” (45–59 years) or “older” (60–75 years), then randomly allocated to the training intervention. A study group (SG, n = 19) participated in NW and a control group (CG, n = 20) performed general gymnastics. The sagittal spinal curvatures and isokinetic trunk muscle endurance were recorded at two time points, pre- and post-training intervention. Significant within NW group changes (p < 0.05) were found for the total work (TW) and average power (AP) of trunk flexors and extensors and the upper thoracic angle in middle-aged women. In older Nordic walkers, significant increases in TW and AP of the trunk flexor muscles were observed, with a negative increase in the trunk inclination angle. In CG, no significant functional or postural changes were observed in response to general gymnastics. NW improved both functional and postural changes in middle-aged women. This study identified the limitations of NW training in older women.

High-intensity interval training in breast cancer survivors: a systematic review

Background

To review the settings and outcomes of high-intensity interval training (HIIT) interventions for breast cancer survivors, and to explore the feasibility of prescribing exercise for breast cancer survivors.

Methods

A systematic search of electronic databases was conducted for studies published up to May 31, 2020. Eligibility criteria included randomized controlled trials of HIIT intervention in breast cancer survivors. Studies were grouped by whether the intervention was conducted during or after breast cancer treatment, and intervention methods and outcomes were reviewed within each group.

Results

Twenty-six studies were identified, and 13 satisfied the inclusion criteria. Intervention was conducted during treatment in 8 studies, and after treatment in 5. Intervention duration ranged from 3 to 16 weeks, with 2 or 3 sessions per week, for a total of 9 to 36 sessions. All interventions were supervised; 12 were lab-based, and 1 was community-based. One of most promising outcomes was improvement of cardiorespiratory fitness by HIIT.

Conclusion

This review found that all studies on HIIT for breast cancer survivors investigated lab-based, supervised interventions, but not home-based or unsupervised. HIIT is a time-efficient method for increasing cardiovascular function in breast cancer survivors, but further research is necessary to determine its effects on other outcomes.

Lumbar lordosis morphology correlates to pelvic incidence and erector spinae muscularity

The retrospective study aimed to investigate the relationship between lumbar lordosis morphology, pelvic incidence and paraspinal muscle. It enrolled asymptomatic adult volunteers aged between 18 and 45 years old. Lumbar lordosis morphology, consisting of total lumbar lordosis (LL), proximal lumbar lordosis (PLL), distal lumbar lordosis (DLL), lumbar lordosis apex (LLA) and inflexion point, was evaluated, as well as pelvic incidence (PI) and muscularity of erector spinae (ES) and multifidus. Pearson correlation was performed to analyze the relationship between each other parameter. Cases were stratified according to pelvic incidence (very low < 30°, low 30°–45°, moderate 45°–60°, and high > 60°), comparison between groups was performed by univariance analysis. 87 asymptomatic adult volunteers (33 females and 54 males) were included in the study. PLL revealed a correlation with LLA (r = 0.603, p = 0.002) and inflexion point (r = 0.536, p = 0.004), but did not DLL with LL apex (r = 0.204, p = 0.058) or inflexion point (r = 0.210, p = 0.051). PI revealed a greater correlation with PLL (r = −0.673, p < 0.001) than with DLL (r = −0.237, p = 0.045). Linear stepwise regression analysis also exhibited the correlation between PI and PLL (R² = 0.452, PLL = 16.2–0.61 * PI, p < 0.001). ES muscularity correlated with LL apex (r = −0.279, p = 0.014) and inflexion point (r = −0.227, p = 0.047). Stratification by PI demonstrated PLL increased across groups (p < 0.001), but DLL was comparable between low and moderate PI group (p = 0.329). Lumbar lordosis morphology appears to accommodate to pelvic incidence and erector spinae muscularity. Proximal lumbar lordosis has a bigger correlation with pelvic incidence than the distal lumbar lordosis. The results are helpful for restoring a rational lumbar lordosis shape in long fusion surgery.

Postural Evaluation in Sports and Sedentary Subjects by Rasterstereographic Back Shape Analysis

Posture is defined as the position of the body in space, the aim of which is to maintain balance, both in static and dynamic conditions. Our purpose was to study various postural variables involved in postural adaptations of athletes practicing symmetric and asymmetric sports at professional level. Methods: Patients include sedentary subjects, competitive athletes practicing symmetrical and asymmetrical sports. Postural evaluation of the three different groups was performed using the rasterstereographic-system Formetric-4D. Results: 157 subjects were recruited. From the comparison between subjects playing symmetrical and asymmetrical sports, arises a statistically significant difference on cervical (p = 0.041) and lumbar (p = 0.047) flèche of Stagnara, with higher values for symmetrical athletes’ group. Hemipelvis torsion (p = 0.031) and lumbar flèche (p ≤ 0.001) of Stagnara are higher in symmetrical athletes’ group (sedentary). Hemipelvis torsion, cervical and lumbar flèche resulted to be higher among athletes (sedentary) (p = 0.016, p = 0.003, p = 0.027). Conclusions: In addition to the competitive sports’ medical examination, a screening with rasterstereographic-system Formetric-4D is suggested to all sedentary subjects, without serious skeletal pathologies which want to start athletic activity. Rasterstereographic-system Formetric-4D is also suggested to all athletes practicing sports, with the aim to identify eventual unknown postures, consequent to reiterated repetition of specific movements.

lncRNA TTN-AS1 facilitates proliferation, invasion, and epithelial-mesenchymal transition of breast cancer cells by regulating miR-139-5p/ZEB1 axis

Breast cancer is a common malignant tumor suffered predominantly by women worldwide, which results in serious levels of morbidity and mortality. To control the effects of the cancer, it is critically important to elucidate the pathophysiological processes by which it occurs and develops. Reports have demonstrated that long noncoding RNAs perform a critical role in the development and metastasis of cancers. The lncRNA TTN-AS1 is considered carcinogenic. Nevertheless, the importance and biological functions of TTN-AS1 in breast cancer require greater exploration. In the current paper, we observed that TTN-AS1 expression was significantly upregulated in breast cancer tissues/cells compared with those that are healthy. TTN-AS1 enhanced the proliferation, migration, invasion, and epithelial-mesenchymal transformation of breast cancer cells. Furthermore, a direct target of TTN-AS1, miR-139-5p was negatively regulated. In addition, zinc finger E-box binding homeobox 1 (ZEB1) is an important nuclear transcription factor, the expression of which is increased in multiple tumors. Here, we also found that ZEB1 is a target of miR-139-5p, of which TTN-AS1 could regulate the expression through competition with miR-139-5p. That is, TTN-AS1 promoted proliferation and invasion of breast cancer cells by interaction with the miR-139-5p/ZEB1 axis. In conclusion, the present study aimed to illustrate the significance of TTN-AS1 in breast cancer metastasis and contribute to potentially innovative strategies for its treatment.

Impact of Rehabilitation on Breast Cancer Related Fatigue: A Pilot Study

Breast cancer fatigue (BCF) is a complex and multidimensional condition characterized by a persistent sense of physical and/or mental stiffness, resulting in a substantial impairment of health-related quality of life in breast cancer survivors. Aim of this prospective cohort study was to evaluate the feasibility and the effectiveness of a 4-week rehabilitation protocol on BCF, muscle mass, strength, physical performance, and quality of life in breast cancer (BC) survivors. We recruited adult BC women with a diagnosis of BCF, according to the International Classification of Diseases 10 criteria, referred to the Outpatient Service for Oncological Rehabilitation of a University Hospital. All participants performed a specific physical exercise rehabilitative protocol consisting of 60-min sessions repeated 2 times/week for 4 weeks. All outcomes were evaluated at the baseline (T0), at the end of the 4-week rehabilitation treatment (T1), and at 2 months follow up (T2). The primary outcome measure was the Brief Fatigue Inventory (BFI); secondary outcomes included: Fat-Free Mass and Fat Mass, assessed by Bioelectrical Impedance Analysis (BIA); Hand Grip Strength Test (HGS); Short Physical Performance Battery (SPPB); 10-meter walking test (10 MWT); 6-min walking test (6 MWT); European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30). Thirty-six women (mean age: 55.17 ± 7.76 years) were enrolled in the study. Significant reduction of BCF was observed both after the 4-week rehabilitation treatment (T1) (BFI: 5.4 ± 1.6 vs. 4.2 ± 1.7; p = 0.004) and at the follow-up visit (T2) (BFI: 5.4 ± 1.6 vs. 4.4 ± 1.6; p = 0.004). Moreover, significant differences (p < 0.001) HGS, SPPB, 10 MWT, 6 MWT, and EORTC QLQ-C30 were found at T1, while at T2 all the outcome measures were significantly different (p < 0.05) from the baseline. The rehabilitation protocol seemed to be feasible, safe, and effective in reducing BCF, improving muscle mass and function, and improving HRQoL in a cohort of BC survivors. The results of this study could improve awareness of this underestimated disease, suggesting the definition of a specific therapeutic exercise protocol to reduce BCF.

Dynamic body posture after unilateral mastectomy: a pilot study

BACKGROUND

Postural changes after unilateral mastectomy may appear in relation to the dominant hand, postoperative duration, and dynamic conditions. This study aimed to compare the postural changes by inclination angles and muscle activities in the static and dynamic sitting position between women with breast cancer who underwent mastectomy and women who did not have breast cancer.

METHODS

The observational study design was conducted. We evaluated 17 women who underwent modified radical mastectomy (MRM) more than 1 year prior to the study. They were categorized into the Rt. mastectomy group (n=7) and the Lt. mastectomy group (n=10). An aged-matched cohort of 8 healthy females was also included. The inclination angle in both static and dynamic sitting positions was measured using the balance board system (BBS), and the muscle activities of 8 muscles were measured in the dynamic sitting position.

RESULTS

There was no significant difference in demographic characteristics between the patients, and all patients were right-handed. The inclination angle of the anterior-posterior axis when leaning forward was significantly increased to the anterior side in the Rt. mastectomy group than in the Lt. mastectomy group. Meanwhile, the inclination angle in the static sitting position and when tilted backward to both directions did not differ among the 3 groups. The inclination angle of the right-left axis was statistically increased to the left side during tilting anterior-left direction in the Rt. Mastectomy group. The muscle activities of the thoracic erector spinae were significantly lower when tilted backward in the Rt. mastectomy group than in the Lt. mastectomy group.

CONCLUSIONS

Compared with left mastectomy, right unilateral mastectomy yielded more postural changes under dynamic sitting state in right-handed female patients with breast cancer. Thus, to maintain the trunk balance and prevent the postural changes after unilateral mastectomy, the postoperative exercise programs for the para-thoracic muscles will be helpful.

Assessment of Postural Balance in Women Treated for Breast Cancer

Background and objectives: Surgery is the primary and most effective treatment of breast cancer. Unilateral mastectomy disrupts the distribution of muscle tension between the right and the left sides of the body. The aim of the study was to evaluate postural balance in patients treated for breast cancer by mastectomy. Materials and methods: A controlled clinical study was conducted on 90 patients who have undergone surgical treatment for breast cancer (mastectomy) 5–6 years prior (Breast Group—BG). The control group (CG) consisted of 74 healthy female volunteers. Analysis of balance was performed using the Alfa stabilography platform. A static test (Romberg’s test) with open and closed eyes was used to assess balance. The following balance parameters were analyzed: path length, statokinesigram area, parameters of deflection and velocity of the foot pressure center. Results: The study demonstrated that patients from BG (5–6 years after surgery) obtained worse results in both tests with open (maximum back deviation, maximum forward deviation, average Y deviation, average Y velocity, path length and path surface area) (p < 0.05) as well as with closed eyes (maximum backward deviation, maximum forward deviation, mean Y deviation and path length) (p < 0.05). Conclusions: Our study demonstrated that women 5–6 years after surgery for breast cancer have impaired balance compared to healthy women, despite physiotherapy.

The recovery of reaching movement in breast cancer survivors: two different rehabilitative protocols in comparison

BACKGROUND

Breast cancer (BC) is the most common cancer in women in the developed world. The about the sequelae of surgery, especially in case of mastectomy or modified radical mastectomy is grown. Nowadays it is important choose appropriate exercise programs to allow recovery in "quantity" but also in "quality" of the movement of the operated upper limb.

AIM

The aim of this study was to verify whether specific exercises for the scapula may induce changes in fluidity of the reaching movement.

DESIGN

Randomized control-trial double-blind study.

SETTING

Exercise training laboratory and gait analysis laboratory.

POPULATION

Sixty-three breast cancer survivors were enrolled.

METHODS

Participants randomized to single rehabilitative treatment (ST), or to group rehabilitative treatment (GT). VAS, DASH and a biomechanical evaluation of upper limb were performed for each group before treatment (T0=baseline), at the end rehabilitative treatment (T1) and after three months of follow-up (T2).

RESULTS

Respect within group analysis, in the ST and in the GT, for VAS an improvement along evaluation times were observed, respectively at T0 to T1 and at T0 to T2 (P<0.001) without a statistically significant difference between groups. At the same, for the DASH, the results showed the same trend without a statistically significant difference between groups. For biomechanical parameters, at T2 velocity was statistically significantly greater in the ST than in the GT (P=0.029) in contrast with the duration, that was statistically significantly greater in the GT than in the ST (P=0.010).

CONCLUSIONS

Both protocols are effective in reducing pain and for functional recovery of the upper limb. The adoption of a non-intensive rehabilitation program should be implemented at least in the first year after the operation, with the adoption of specific myofascial exercises on the scapulo-thoracic joint with better results in the "qualitative" recovery of the achievement.

CLINICAL REHABILITATION IMPACT

Our study emphasizes the importance of rehabilitation in BC survivors after mastectomy, even during the course of radiotherapy and chemotherapy and the adoption of specific myofascial exercises on the scapulo-thoracic joint and specific exercises of muscular stretching on the pectoral muscle. Therefore, the proposed rehabilitation protocol must be "clipped" and "integrated" according to the specific objectives for each individual patient.

Comparison of Spinal Alignment and Mobility in Women With and Without Post Modified Radical Mastectomy Unilateral Lymphoedema

INTRODUCTION

Unilateral lymphoedema and breast resection after modified radical mastectomy might create impairment of spinal alignment and mobility. The aim of this study was to compare spinal alignment and mobility in women with and without post modified radical mastectomy unilateral lymphoedema.

MATERIALS AND METHODS

Twenty women with post modified radical mastectomy unilateral lymphoedema (lymphoedema group) and 18 healthy women (control group) were included in this study. The sagittal and frontal spinal alignment and mobility were assessed with a Spinal Mouse (Idiag, Fehraltorf, Switzerland). The severity of the lymphoedema was evaluated with circumferential measurements.

RESULTS

In the lymphoedema group, the volume difference of the arms was 448.31 ± 78.14 mL, known as moderate severity lymphoedema. It was seen that the sagittal thoracic curvature (P = .017) and the frontal inclination angle (P = .048) were higher in the lymphoedema group in comparison with the control group. In the lymphoedema group, the frontal inclination angle changed towards the unaffected side (P < .001). No significant differences were found between groups in the other parameters related to spinal curvature and mobility (P > .05).

CONCLUSION

The sagittal thoracic curvature and the frontal inclination angle towards the unaffected side increased in women with post modified radical mastectomy unilateral lymphoedema. The sagittal and frontal spinal alignment changes should be taken into consideration for the assessment and the treatment of unilateral lymphoedema.
