Influence of type 1 diabetes on the postural control of women in the third gestational trimester

Influence of the anchor system on body sway in women affected and not affected by lymphedema secondary to breast cancer: A cross-sectional study

BACKGROUND

Postural control is an essential ability for functional independence modified by therapeutic approaches and morbidities secondary to breast cancer. The anchor system enables additional haptic perception of body position in front of the support base and can be used alone or in conjunction with sensorimotor training.

RESEARCH QUESTION

What is the influence of the anchor system, through different manual contacts on the upper limb, on body sway in women affected and not affected by lymphedema secondary to breast cancer treatment?

METHODS

Cross-sectional study involving 60 women homogeneously distributed to the group affected by lymphedema (GAL), with a mean age of 62.53 (SD = 12.54) years and upper limb volume difference (ULVD = Ipsilateral - Contralateral) of 636.21 (SD = 387.94) cm3, and group not affected by lymphedema (GNAL), with a mean age of 57.24 (SD = 11.43) years and ULVD of -8.91 (SD = 121.72) cm3. Baropodometry was used to assess body sway, through the presence and absence of the visual sense, associated with different manual contacts of the anchor system designated absence, simulation of use, unilateral and bilateral contact. The Shapiro-Wilk and Student's T-tests with Bonferroni Post-Hoc were used in the statistical analysis (p ≤ 0.05).

RESULTS

The GAL expressed non-significant values compared to the GNAL in the absence of visual sense and non-use of the anchor system. The unilateral contact of the anchor system on the preferred upper limb in the presence of the visual sense, and bilateral contact of the anchor system in the presence and absence of the visual sense promoted a significant reduction of body sway in both groups.

SIGNIFICANCE

In breast cancer survivors, the anchor system with bilateral contact effectively maintains postural control, regardless of the visual sense and the volume of the upper limb.

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.

Assessment of physical fitness during pregnancy: validity and reliability of fitness tests, and relationship with maternal and neonatal health - a systematic review

Objectives

To systematically review studies evaluating one or more components of physical fitness (PF) in pregnant women, to answer two research questions: (1) What tests have been employed to assess PF in pregnant women? and (2) What is the validity and reliability of these tests and their relationship with maternal and neonatal health?

Design

A systematic review.

Data sources

PubMed and Web of Science.

Eligibility criteria

Original English or Spanish full-text articles in a group of healthy pregnant women which at least one component of PF was assessed (field based or laboratory tests).

Results

A total of 149 articles containing a sum of 191 fitness tests were included. Among the 191 fitness tests, 99 (ie, 52%) assessed cardiorespiratory fitness through 75 different protocols, 28 (15%) assessed muscular fitness through 16 different protocols, 14 (7%) assessed flexibility through 13 different protocols, 45 (24%) assessed balance through 40 different protocols, 2 assessed speed with the same protocol and 3 were multidimensional tests using one protocol. A total of 19 articles with 23 tests (13%) assessed either validity (n=4), reliability (n=6) or the relationship of PF with maternal and neonatal health (n=16).

Conclusion

Physical fitness has been assessed through a wide variety of protocols, mostly lacking validity and reliability data, and no consensus exists on the most suitable fitness tests to be performed during pregnancy.

Immediate Effect of Manual Therapy on Tibiotarsal Joint Mobility and Static Balance in Individuals With Diabetes

Objectives

The objective of this study was to evaluate the immediate effect of manual therapy on ankle joint mobility and static balance in patients with diabetes.

Methods

Forty patients, at a mean age of 59.35 ± 7.85, with type 2 diabetes mellitus and neurologic symptoms according to a Neuropathy Symptom Score protocol with amplitude, were included. The patients were divided into 2 groups: sham group and intervention group, which underwent manual manipulation intervention and 7-day follow-up. Joint range-of-motion analysis was performed using digital goniometry and static discharge of weights assessed by computerized baropodometry with open and closed eyes. The Shapiro-Wilk normality test was used to analyze the distribution. The data showed normal distribution, so the analysis of variance tests followed by Tukey's tests were used. SAS statistical software was used and the significance level was 5%.

Results

The results of the intervention group showed an increase in the variable ankle goniometry over time compared to the sham group. The dorsiflexion movement on the right side obtained major gains over time; in addition, plantar flexion increased.

Conclusion

Based on the participants evaluated in this study, manual therapy increased the ankle joint amplitude and improved the static balance in individuals with diabetes.
