Effects of 4 weeks of dynamic neuromuscular stabilization training on balance and gait performance in an adolescent with spastic hemiparetic cerebral palsy

The Role of Dynamic Neuromuscular Stabilization Exercises in Stress Urinary Incontinence Among Females Aged 18-40 Years

BACKGROUND AND OBJECTIVE

Stress urinary incontinence (SUI) is prevalent among females across various age groups, yet societal taboos and unawareness contribute to under-reporting and hinder effective management strategies. This study aimed to evaluate the efficacy of dynamic neuromuscular stabilization (DNS) compared to traditional Kegel exercises in females with stress urinary incontinence, focusing on assessing the impact of DNS on pelvic floor strength and core musculature activation to provide valuable insights into urinary continence management.

METHODOLOGY

This is a single-blinded, randomized trial with 90 females aged 18-40 years assessed perineometer readings, pelvic floor electromyography (EMG), and transverse abdominis activation via pressure biofeedback.

RESULTS

Significant improvements in pelvic floor strength and core musculature activation were observed in the DNS group compared to the Kegel exercise group. Perineometer values, EMG measurements, and pressure biofeedback unit readings demonstrated substantial enhancements post-intervention in both groups. Effect sizes, including Cohen's D and point biserial correlation coefficient, indicated medium to large effects favoring the DNS intervention.

CONCLUSION

DNS is superior to Kegel exercises for SUI management, emphasizing the importance of targeting core musculature. Future research should explore long-term outcomes and patient-reported measures for a comprehensive understanding.

Comparing the Efficacy of Dynamic Neuromuscular Stabilization Exercises and Kegel Exercises on Stress Urinary Incontinence in Women: A Pilot Study

Background and objective Stress urinary incontinence (SUI) is a prevalent condition affecting women of various age groups, significantly impacting their quality of life. To address this multifaceted issue, a comprehensive approach that goes beyond traditional pelvic floor exercises is needed. Dynamic neuromuscular stabilization (DNS) exercises, targeting the integrated spinal stabilization system, offer a promising alternative. Thus, this study aimed to compare the effectiveness of DNS exercises and Kegel exercises in managing SUI among women. Methods This single-blinded, pilot study involved 24 women aged 18-40 years with mild to moderate SUI. Participants were divided into DNS and Kegel exercise groups. Outcome measures included perineometer readings, electromyography (EMG) data, and the Urogenital Distress Inventory-6 (UDI-6). Statistical analysis compared baseline and 12-week data within and between groups, and rank-biserial correlation coefficient (r) as a measure of effect size in our study was calculated. Results At 12 weeks, the DNS group showed significant improvement in pelvic floor muscle strength compared to Kegel exercises (p = 0.005). Both groups had significantly enhanced pelvic floor muscle strength (p < 0.05). A significant change occurred for EMG average, EMG peak, and EMG maximum voluntary contraction (MVC) at 12 weeks (average p = 0.005; peak p = 0.001; MVC p = 0.009), with significant improvements in both groups (p < 0.05). For UDI-6, a significant difference emerged between the two groups at 12 weeks (p < 0.05), with significant improvements in both groups individually from baseline to 12 weeks (p < 0.05). The effect size "r" for all variables indicated a medium to large effect size, underscoring the substantial and significant impact of DNS exercises in managing SUI among women compared to Kegel exercises. Conclusion This study suggests that DNS exercises, emphasizing the coordinated activation of the diaphragm, abdominals, multifidus, and pelvic floor, may provide a more effective approach for managing SUI in women compared to traditional Kegel exercises.

Effect of the Dynamic Neuromuscular Stabilization Technique on Functional Capacity in Overweight and Obese Individuals: A Randomized Controlled Trial

Background Individuals with overweight and obesity (OW/OB) have poor performance in weight-bearing exercises, resulting in low functional capacity. The dynamic neuromuscular stabilization (DNS) technique was created to engage the core-postural chain in conjunction with the core muscles, generating enough intra-abdominal pressure to dynamically support the spine through muscular activity. DNS is a strategy that emphasizes the activation of the spine's intrinsic stabilizers, as well as proper breathing patterns, before any intended functional movement. The aim and objective of this study was to determine the effectiveness of the DNS technique on functional capacity in OW/OB individuals and to compare the effectiveness of the DNS and conventional approach. Methods The study recruited 100 individuals, who were separated into an experimental group (DNS technique) and a control group (conventional exercises), each with 50 participants. Outcome measures, including a six-minute walk test (SMW test) and body mass index (BMI), were taken pre-treatment and post-treatment. Results and discussion Based on the inclusion criteria of this study, the age group included was 20 to 25 years old. Pre- and post-treatment statistically significant changes were observed in the experimental and control groups in the BMI and SMW test. However, the BMI (kg/m2) was not statistically significant in the experimental group (t-value=-0.15, p=0.87) and control group (t-value=-0.22, p=0.82). Moreover, in the SMW test (meter), no statistical significance was found in the experimental group (t-value=-0.15, p=0.87) and control group (t-value=- 0.22, p=0.82). Conclusions Both groups are effective in increasing the functional capacity of obese and overweight individuals. The study indicates a strong need for further research into its long-term effectiveness in the OW/OB population.

EFFECTS OF CORE STABILIZATION EXERCISE ON MUSCLE ACTIVITY DURING HORIZONTAL SHOULDER ADDUCTION WITH LOADS IN HEALTHY ADULTS: A RANDOMIZED CONTROLLED STUDY

The importance of core stabilization exercises for extremities associated with dynamic spinal stabilization prior to movement has been demonstrated. However, no previous studies have investigated the muscle-coordinated effects on the upper trapezius (UT), anterior deltoid (AD), pectoralis major (PM), bilateral transverse abdominis (TrA), bilateral internal oblique (IO), and bilateral external oblique (EO) in healthy adults. The purpose of this study was to compare the effects of the dynamic neuromuscular stabilization (DNS) breathing technique and the abdominal bracing (AB) technique on UT, AD, PM, bilateral IO/TrA, and bilateral EO motor control in healthy participants during horizontal shoulder adduction. Thirty-six participants, eight of whom were female, were randomized into an AB and a DNS group and performed horizontal shoulder adduction with loads (8 and 17 lb). The clinical outcomes were UT, AD, and PM muscle activation and TrA/IO and EO muscle activation. Paired t-tests were used to analyze electromyography (EMG) data to determine statistically significant differences in muscle activity between the two techniques. For the EMG analysis, the maximal voluntary isometric contraction was measured for normalization and then divided by the EMG amplitude value. The results showed that UT, AD, and PM muscle amplitudes were lower and TrA/IO and EO muscle amplitudes were higher with DNS than with AB ([Formula: see text]). Our findings provide clinical evidence that core exercise with DNS is more effective in lessening UT, AD, and PM muscle activation and improving bilateral TrA/IO motor control than with AB.
