Background/aims Studies have shown the efficacy of stretching to increase the hip flexion range of motion but studies regarding its effects are not unanimous about the most efficient technique. The aim of this study was to compare the effect of two stretching techniques on the neuromuscular properties of the hamstring muscles. Methods A total of 18 women (aged 24 ± 2.52 years old) participated, and were divided into three groups: a control group, a passive static stretching group and a propioceptive neuromuscular facilitation stretching group. Evaluations of variables of the hamstring muscles were performed before and after the training period. The intervention was carried out for 30 seconds, three times a week for a total of 4 weeks. Results A significant difference was found in the range of motion in the passive static stretching group (pre=80.8° [±11.0] and post=94.5° [±10.2]; t(5)=−3.755; P=0.013) and in concentric torque (passive static stretching group – pre=66.3 Nm [±12.9] and post=70.0 Nm [±8.1]; t(5)=−1.267; P=0.023; propioceptive neuromuscular facilitation stretching group – pre=79.1 Nm [±12.7] and post=83.5 Nm [±11.6]; t(5)=−1.917; P=0.014; control group – pre=71.1 Nm [±10.1] and post=74.1 Nm [±14.6]; t(5)=−1.275; P=0.003). Conclusions Passive static stretching was superior to propioceptive neuromuscular facilitation when comparing the increase range of motion in hip flexion, even without neural and structural changes in hamstring muscles after a 4-week period.

Hamstring Flexibility

Background: flexibility that is one of basic aspects of any sport program , can be developed and acquired through various stretching exercises. This study examined the effect of six-weeks of static stretching on hamstring flexibility in high school females. Methods: Thirty healthy high school females aged 15 to 17 years were randomly assigned to one of two groups. The training group underwent static stretch training of the hamstring with a six-weeks protocol training sessions were 3 days per week, including 4 30-seconds stretches per day for each of subjects. The other group acted as control group. Before and after six-weeks of stretching, flexibility of the hamstring muscles was determined by Sit & Reach Test. Results: A significant increase in flexibility of hamstring was found in training group (mean 31cm to 39/87cm), and no significant difference was revealed in hamstring flexibility after the six-weeks static stretching for the control group. Conclusion: This study indicated that the static stretching significantly increased the hamstring flexibility and suggests that subjects use static stretching for increasing their hamstring flexibility.DOI: http://dx.doi.org/10.3126/ijls.v8i5.10914

SUMMARY The aim of this study was to evaluate how cavity linings with different elastic modulus can influence the marginal adaptation (MA) of Class II composite restorations before and after thermo-mechanical loading. Materials and Methods: Forty Class II cavities with margins extending 1 mm below the cement-enamel junction were prepared in extracted human third molars. In each group except the control group, a lining material of 1-mm thickness was applied to the bottom of the cavity and polymerized before placing the resin composite Herculite XRV Ultra (group A: control; group B: Premise Flowable lining; group C: Herculite XRV Ultra lining; and group D: Optibond FL lining). MA was evaluated (with a scanning electron microscope) before and after loading (200,000 loading cycles). Statistical analysis was done using the Shapiro-Wilks test, the analysis of variance test, and Duncan post hoc test at p<0.05. Results: Before loading, the percentages of continuous margins in dentin were superior (p<0.05) for groups C and D (71.1% and 87.2%, respectively) compared to groups A and B (55.7% and 48.3%, respectively). After loading, group D (79.8%) was statistically superior in dentin compared to all of the other groups (43.6%, 35.9%, and 54.4%, respectively). In occlusal enamel, no significant difference was found between groups. The percentage of enamel fractures and the percentage of noncontinuous margins in proximal enamel were high, with no significant difference between liners. It can be concluded that for the materials used in this study, a 1-mm-thick lining with an extremely low elastic modulus (2-3 GPa) could redistribute shrinkage stress. The use of a flowable composite did not significantly improve MA.

Abstract Objective: The functional orientation of the acetabular cup depends on the pelvic orientation when standing. Therefore, predicting the standing orientation of the pelvis after total hip arthroplasty( THA )is important to the preoperative plan. This study aimed to explore the rule suitable for different categories of patients.Methods: A total of 262 patients who had undergone hip arthroplasty in our hospital from 2011 to 2019 were retrospectively analyzed. Based on the spine and hip joint, they were divided into 5 categories: no flexion contracture of the hip joint - good lumbar range of motion (group A); no flexion contracture of the hip joint - limited lumbar motion (group B: B1, tanterior pelvic plane tilt (APPt)>0 °; B2, APPt<0 °); hip flexion contracture - good lumbar range of motion (group C); and hip flexion contracture - limited lumbar motion (group D). Changes of the pelvic sagittal parameter before and after THA were analyzed. Results: In group A, there was no significant difference in pelvic incidence (PI) and sagittal vertical axia (SVA) between preoperation and postoperation (P>0.05), but the mean value of sacral slope (SS) (from 44.99 °to 40.50 °), lumbar lordosis( LL) (from 51.42 to 47.45), pelvic tilt (PT) (from 8.71 °to 11.91°), and tanterior pelvic plane tilt (APPt) (from 4.5 °to 1.27 °) had statistic difference (P<0.05); In group B1 and B2, PI, SVA, SS, PT, LL, and APPt had no significant difference before and after operation (P>0.05); In group C, significant difference was not observed in PI (P>0.05), but found (P<0.05) in LL (from 52.17° to 43.43°), SS(44.90° to 38.34°), PT (from 5.70° to 13.36°), APPt (from 9.18° to 2.18°), and SVA (from 3.46cm to 1.16cm). In group D: the pelvis was in supination state before and after operation, and the spine sagittal position was imbalanced. Neither was there significant difference in SVA, PI, SVA, SS, ll and APPt between preoperation and postoperation (P>0.05). In addition, Harris scores of different groups changed accordingly. Conclusion: The sagittal rotation of the pelvis caused by different conditions of the spine-hip has a certain change law after total hip arthroplasty.

Background/Aim. Nocturia often occurs in patients with benign prostate hyperplasia (BPH). The aim of the study was to investigate the frequency of nocturia in patients with BPH. Nocturia and other factors associated with it were also investigated. Methods. Forty patients with the confirmed diagnosis of BPH were studied. Transurethral and transvesical prostatectomy were performed in all the patients. Symptoms were evaluated with the International Prostate Symptom Score before, as well as three and six months after the surgery. All the results were compared with the control group. Results. There was no statistically significant difference between the patients before and after the surgery regarding nocturia. There was, however, a statistically significant difference between the operated patients and the control group regarding nocturia, as well as a statistically significant correlation between noctruia and the age of the patients in both the investigated and the control group. A correlation also existed between nocturia and the prostatic size. Conclusion. There was no statistically significant improvement in symptoms of nocturia after the surgery. It is necessary to be very careful in decision making in patients with nonabsolute indiction for surgery and isolated bothersome symptom of nocturia. Age of a patient should also be considered in the evaluation of favorable result of the surgery because of a significant correlation between noctura and the age of a patient.

Background/aims High-intensity static stretching is assumed to increase the range of motion and/or decrease muscle stiffness; however, the effects of high-intensity static stretching on the quadriceps muscle have been debated. Hot pack application before high-intensity static stretching was assumed to decrease stretching pain, which is the main problem in high-intensity static stretching, and decrease quadriceps muscle stiffness. This study aimed to examine hot pack application before high-intensity static stretching on stretching pain, knee flexion range of motion, and quadriceps muscle stiffness. Methods In total, 21 healthy sedentary male participants randomly performed two interventions: high-intensity static stretching and hot pack application before stretching. Static stretching was performed at three 60-second stretching interventions with a 30-second interval. Then, a 20-minute hot pack was applied before high-intensity static stretching. The knee flexion range of motion and shear elastic modulus of the quadriceps muscle were measured by ultrasonic shear-wave elastography before and after the static stretching intervention. Results Stretching pain after hot pack application before stretching was lower than high-intensity static stretching alone. Significant increases were also found in knee flexion range of motion after both stretching interventions, but no significant difference was noted in the increase in the knee flexion range of motion with or without hot pack application. No significant change was found in quadriceps muscle stiffness in either intervention. Conclusions The results suggest that hot pack application before high-intensity static stretching could decrease stretching pain, but no significant difference in knee flexion range of motion increase was found.

Clinical Scenario:Stretching is applied for the purposes of injury prevention, increasing joint range of motion (ROM), and increasing muscle extensibility. Many researchers have investigated various methods and techniques to determine the most effective way to increase joint ROM and muscle extensibility. Despite the numerous studies conducted, controversy still remains within clinical practice and the literature regarding the best methods and techniques for stretching.Focused Clinical Question:Is proprioceptive neuromuscular facilitation (PNF) stretching more effective than static stretching for increasing hamstring muscle extensibility through increased hip ROM or increased knee extension angle (KEA) in a physically active population?Summary of Key Findings:Five studies met the inclusion criteria and were included. All 5 studies were randomized control trials examining mobility of the hamstring group. The studies measured hamstring ROM in a variety of ways. Three studies measured active KEA, 1 study measured passive KEA, and 1 study measured hip ROM via the single-leg raise test. Of the 5 studies, 1 study found greater improvements using PNF over static stretching for increasing hip flexion, and the remaining 4 studies found no significant difference between PNF stretching and static stretching in increasing muscle extensibility, active KEA, or hip ROM.Clinical Bottom Line:PNF stretching was not demonstrated to be more effective at increasing hamstring extensibility compared to static stretching. The literature reviewed suggests both are effective methods for increasing hip-flexion ROM.Strength of Recommendation:Using level 2 evidence and higher, the results show both static and PNF stretching effectively increase ROM; however, one does not appear to be more effective than the other.

El objetivo de este estudio fue comprobar los efectos de un programa de estiramiento con la técnica contracción-relajación-agonista-contracción (CRAC) sobre la capacidad de salto (CS) y el rango de movimiento (ROM). Un total de 21 jugadores de élite de fútbol sala participaron en el presente trabajo. Los participantes fueron asignados a un grupo control (GC) y a un grupo experimental (GE) según su CS. Antes y después de la intervención se midió la CS y el ROM de flexión de cadera con la rodilla extendida (FCRE) y dorsi-flexión de tobillo (DFTRE). Para la medición del CS y del ROM se utilizó una plataforma de contacto y un inclinómetro ISOMED, respectivamente. El GE realizó un programa de estiramientos en los isquiosurales y tríceps sural durante 4 semanas con una frecuencia semanal de 5 días. Los jugadores aumento significativamente el ROM FCRE (p = 0,02) con efecto fuerte (hp2 = 0,730) y ROM DFTRE (p = 0,01) con efecto moderado (hp2 = 0,546), de los valores de CMJ (p = 0,03) con efecto fuerte (hp2 = 0,650) y de los valores de índice de aprovechamiento de la capacidad elástica [IACE] (p = 0,04) con efecto fuerte (hp2 = 0,742) en el GE después de los estiramientos. Los jugadores del GC aumentaron significativamente el rendimiento en el CMJ (p = 0,02) con efecto moderado (hp2 = 0,519) e IACE (p = 0,04) con efecto moderado (hp2 = 0,548); además, se observaron diferencias significativas en los valores de IACE (p = 0,02) entre ambos grupos. Los resultados de este estudio permiten concluir que un periodo de entrenamiento con el método CRAC mejora el ROM y la CS en jugadores profesionales de fútbol sala. The purpose of this study was to examine the effects of a stretching program with the contraction-relaxation-agonist-contraction technique (CRAC) on jumping performance (JP) and range of motion (ROM). A total of 21 elite futsal players participated in the present study. Participants were assigned to a control group (CG) and an experimental group (EG) according to their jumping ability. Before and after the intervention, the JP and ROM of hip flexion with the extended knee (FCRE) and dorsi-flexion of the ankle (DFTRE) were measured. For the measurement of the JP and the ROM, a contact platform and an ISOMED inclinometer were used, respectively. The EG performed a stretching program in the hamstrings and triceps sural for 4 weeks with a weekly frequency of 5 days. The players significantly increased the FCRE ROM (p = 0.02) with strong effect (hp2 = 0.730) and ROM DFTRE (p = 0.01) with moderate effect (hp2 = 0.546), of the values ​​of CMJ (p = 0.03) with strong effect (hp2 = 0.650) and of the values ​​of index of utilization of the elastic capacity [IACE] (p = 0.04) with strong effect (hp2 = 0,742) in the EG after the stretching. The CG players significantly increased the performance in the CMJ ​​(p = 0.02) with moderate effect (hp2 = 0.519) and IACE (p = 0.04) with moderate effect (hp2 = 0.548); in addition, significant differences were observed in the values ​​of IACE (p = 0.02) between both groups. The results of this study allow us to conclude that a training period with the CRAC technique improves ROM and JP in professional futsal players.

Abstract Purpose The benefits of providing static stretching exercise targeting the hips in patients with non-specific Low Back Pain (NSLBP) are not well established. The objective of the study was to verify the effects of static stretching on function, pain and range of motion on patients with non-specific Low Back Pain (NSLBP). Methods Thirty females with NSLBP were randomly assigned to two control (n = 15) and experimental (n = 15) groups. The experimental group received 3 stretch practice sessions per week for a period of 8 weeks. The Oswestry low back pain Disability Questionnaire (ODI), visual analog scale (VAS), and passive hip range of motion (PROM) were employed before and after the intervention. Results The results of mixed model analysis of variance indicate that the group × time interactions was not significant (p > 0.05) for all measurement outcomes. However, there was a main effect for Time (ODI: p = 0.002, VAS: p = 0.001, PROM-R: p = 0.016, PROM-L: p = 0.001). Such that the ODI, VAS, PROM-R, and PROM-L were showed significant differences before and after the intervention in the experimental group. Conclusions The results demonstrated a significant difference in PROM, pain, and disability after 8 weeks of stretching exercises in participants with NSLBP and limited hip extension. Therefore, it would be reasonable to infer that NSLBP might be partly related to hip flexors tightness.
