A Comparison of the Effectiveness of Neurodynamic Sliding Technique and Self-Myofascial Release Technique for Reducing Hamstring Tightness in Healthy Individuals: A Prospective Study.

BACKGROUND: Hamstring tightness is prevalent among college-going students aged 18-25 years, leading to an increased risk of recurrent injury, reduced athletic performance, post-exercise soreness, and decreased coordination. Myofascial release and neurodynamic sliding technique are two interventions used to alleviate this issue. Myofascial release is a concept that involves pain originating from the muscle and fascia. The neurodynamic sliding technique is a method of producing sliding movement of neural structures relative to their mechanical interfaces. METHODS: This study involved 70 individuals with hamstring tightness who met the inclusion and exclusion criteria. Participants were assigned to Group A or Group B using a convenient sampling method. Group A received neurodynamic sliding technique treatment, while Group B received a self-myofascial release. Both interventions were administered for two months. The outcome measures used in this study were active knee extension and lower extremity functional scale, which were evaluated before and after the intervention. RESULTS AND IMPLICATIONS: Within-group comparisons indicated that both Group A and Group B showed significant improvements in hamstring flexibility. Between-group comparisons of active knee extension (AKE) and lower extremity functional scale (LEFS) immediately after the intervention showed statistically significant results. These findings suggest that both the neurodynamic sliding technique and self-myofascial release are effective in improving hamstring flexibility. This study has implications for clinical practice, as both interventions may be used to address hamstring tightness. CONCLUSION: Our study found that both the neurodynamic sliding technique and self-myofascial release can improve hamstring flexibility. However, the neurodynamic sliding technique was found to be more effective than self-myofascial release. Further research is necessary to determine the optimal protocol for these interventions and their effectiveness in clinical populations with hamstring tightness or injury.

A Novel Method for Muscle Elongation in Myalgia with Naqvi's-Dynamic Electrical Therapy Approach (DELTA)©: The First-Ever Case Report.

Lifestyle-related neck and shoulder pain can be attributed to trapezius myalgia (TM) in a significant number of cases. Apart from pain, manifestations of TM include tightness of the trapezius muscle, especially in the upper fibres. Naqvi's-Dynamic Electrical Therapy Approach (Naqvi's-DELTA)© is a novel electrotherapeutic intervention based on the principle of myofibril elongation obtained by interference of poled vector current that is moved along the length of muscle fibres. A 22-year-old male approached the physiotherapy outpatient department (OPD) with the chief complaint of persistent neck pain and stiffness for three years that adversely affected his activities of daily living (ADLs). The pain was evaluated using a visual analog scale (VAS), restrictions in the range of motion (ROM) were determined by the cervical range of motion (CROM) device, and limitations in ADLs were assessed by neck disability index (NDI). Naqvi's-DELTA© was administered once a day for seven days, with each session lasting for 15 minutes. After the intervention, an evident beneficial effect was noted in all outcomes measures suggesting that this novel method was effective in decreasing pain, stiffness, and limitations in ADLs. Further investigation to explore this method for myalgia management is warranted.
