Context: Chronic plantarflexor (PF) stretching during ankle immobilization helps preserve calf girth, plantarflexion peak torque, and ankle dorsiflexion (DF) motion. Immobilization can lead to decreases in muscle peak torque, muscle size, and joint range of motion (ROM). Recurrent static stretching during a period of immobilization may reduce the extent of these losses. Objective: To investigate the effects of chronic static stretching on PF peak torque, calf girth, and DF ROM after 2 weeks of ankle immobilization. Design: Randomized controlled clinical trial. Setting: Athletic training facility. Participants: A total of 36 healthy college-aged (19.81 [2.48]) females. Interventions: Subjects were randomly assigned to one of 3 groups: control group, immobilized group (IM), and immobilized plus stretching (IM+S) group. Each group participated in a familiarization period, a pretest, and, 2 weeks later, a posttest. The IM group and IM+S group wore the Aircast Foam Pneumatic Walker for 2 weeks on the left leg. During this time, the IM+S group participated in a stretching program, which consisted of two 10-minute stretching procedures each day for the 14 days. Main Outcome Measures: One-way analysis of variance was used to determine differences in the change of ankle girth, PF peak torque, and DF ROM between groups with an α level of <.05. Results: A significant difference was noted between groups in girth (F2,31 = 5.64, P = .01), DF ROM (F2,31 = 26.13, P < .001), and PF peak torque (F2,31 = 7.74, P = .002). Post hoc testing also showed a significance difference between change in calf girth of the control group compared with the IM group (P = .01) and a significant difference in change of peak torque in the IM+S group and the IM group (P = .001). Also, a significant difference was shown in DF ROM between the control group and IM+S group (P = .01), the control group and the IM group (P < .001), and the IM+S group and the IM group (P < .001). Conclusion: Chronic static stretching during 2 weeks of immobilization may decrease the loss of calf girth, ankle PF peak torque, and ankle DF ROM.

Four hundred sixty-seven high school athletes were screened in apreparticipation athletic physical. Forty-six (9.8%) of these athletes presented with asymptomatic, nontraumatic unilateral hyperextension. Twenty-three athletes were reexamined and compared to a normal control group. A 2.5-cm, statistically significant heel-to-heel difference was recorded in the hyperextension group. Between the involved hyperextended and uninvolved legs, there were differences in average range of motion (132.04° vs. 130.74°, respectively), average manual anterior translation by KT-1000 (5.39 mm vs. 5.15 mm, respectively), average posterior translation (2.07 mm vs. 2.00 mm, respectively), average peak quadriceps torque (86.25 ft-lb vs. 84.06 ft-lb, respectively), and hamstring average peak torque (53.89 ft-lb vs. 52.93 ft-lb, respectively), though these differences were not statistically significant. In the control group, there was no heel-to-heel difference in the right versus the left knee. Heel-to-heel difference between the experimental and control groups was statistically significant. There was no statistically significant difference between range of motion, anterior translation, or posterior translation between the experimental and control groups.

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.

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.

Context: Roller massage (RM) is a popular myofascial intervention. To date, no research has investigated the effects of RM on experienced and nonexperienced individuals and if there are differences between a prescribed RM program and a self-preferred program. Objective: The main objective was to measure the effects of a prescribed RM program with a foam roller on knee passive range of motion (ROM) and pressure pain threshold (PPT) among experienced and nonexperienced individuals. A secondary objective was to determine if there are differences between a prescribed RM program and a self-preferred program in experienced individuals. Design: Pretest and posttest observational study. Setting: University kinesiology laboratory. Participants: A total of 60 healthy adults (age = 26 [5.3] y) were allocated into 3 groups of 20 subjects: experienced, nonexperienced, and control. The experienced and nonexperienced groups followed a prescribed 2-minute RM intervention. The control group did their own 2-minute self-preferred program. Main Outcome Measures: Knee passive ROM and PPT. Results: For the experienced and nonexperienced, the between-group analysis revealed a statistically significant difference for ROM and PPT (P < .001). Within-group analysis revealed a posttest knee passive ROM increase of 8° for experienced and 7° for the nonexperienced. For PPT, there was a posttest increase of 180 kPa for the experienced and 169 kPa for the nonexperienced. For the prescribed versus self-preferred program, the between-group analysis (experienced vs control) revealed a statistically significant difference (P < .001). The within-group analysis revealed a posttest knee passive ROM increase of 8° for the prescribed and 5° for the self-preferred program. For PPT, there was a posttest increase of 180 kPa for the prescribed program and 137 kPa for the self-preferred program. Conclusion: These findings suggest that experienced and nonexperienced individuals have similar responses to a prescribed RM program. A prescribed RM program may produce better outcomes than a self-preferred program.

The Graston technique (GT) is prescribed to increase range of motion (ROM) in pathological patients, however little evidence exists regarding the effect GT has on healthy soft tissue joint ROM. The purpose of this study was to evaluate the effect GT would have on ankle dorsifl xion when compared with traditional static stretching (TS) among 50 healthy track and field volunteers. Participants were randomly assigned to a GT, TS, or control group. GT yielded a greater increase in talocrural joint dorsifl xion when compared with TS. GT seems to provide mobility to healthy tissue, such as fascia and muscle not previously reported.

Background: There is continued controversy related to flexibility gains from different stretching protocols and within single protocols. Stretching methods include static, ballistic, dynamic, and proprioceptive neuromuscular facilitation (PNF). A combination of stretching methods may be an improved way to increase active knee range of motion (ROM). This study evaluated a single program formulated with static and ballistic components. Objective: To compare active knee ROM following stretching programs which either included combined static and ballistic stretching (CSBS) or static stretching (SS) alone. It was hypothesized that CSBS would show a greater increase in active knee ROM than SS. Setting: The pre- and post- measurements were performed in a laboratory. Subjects were randomly assigned to either treatment group or a non-stretching control group and given written instructions on how to perform their designated protocol at home. Subjects: Forty-three (33M, 10F) healthy collegiate aged participants (24.0 + 3.69 yrs, 176.21 + 10.0 cm, 78.15 + 12.93 kg) with no history of injury to the lower extremity or low back for the previous 6 months were eligible to participate in the study. Interventions: Two treatment groups either performed SS or CSBS for 30 seconds on each leg, twice a day for 2 weeks. All subjects but 3 provided both legs, and each leg was evaluated separately, providing 83 total measurements. Main Outcome Measures: A Johnson Digital Inclinometer was used to measure active knee extension. A mixed ANOVA with a Tukey post hoc test was used for statistical analysis. Results: There was no statistically significant difference in active knee ROM between groups at the pre-test, F(2,80)=1.062, p=.351, partial ƞ2=.026 (SS: 52.56 + 7.50º, CSBS: 49.84 + 8.91⁰, control: 49.39 + 10.09⁰). There was a statistically significant difference in active knee ROM between groups at the post-test, F(2,80)=29.034, p .05). There was homogeneity of covariance’s, as assessed by Box's test of equality of covariance matrices (p = .076). There was homogeneity of variances, as assessed by Levene's test of homogeneity of variance (p>.05). Conclusions: SS and CSBS are equally effective for improving active knee ROM. A trend indicating CSBS showing only slightly greater differences may be due to limited time allowed to master the CSBS method, with no supervision during stretching sessions.

Postoperative Ileus (POI) is one of the most common problems after obstetrics, gynecologic and abdominal surgeries. Sham feeding, such as gum chewing, accelerates the return of bowel function and the length of hospital stay. The present study aims to evaluate the effect of chewing gum on bowel motility in women undergoing post-operative cesarean section. Intervention study was used at the Postpartum Department of Maternity and Children Hospital, KSA. A randomized controlled clinical trial research design. Through a convenience technique, 80 post Caesarian Section (CS) women were included in the study. Data were collected through three tools: Tool (I): Socio-demographic data and reproductive history interview schedule. Tool (II): Postoperative Assessment Sheet. Tool (III): Outcomes of gum chewing and the length of hospital stay.  Method: subjects were assigned randomly into two groups of (40) the experimental and (40) the control. Subjects in the study group were asked to chew two pieces of sugarless gum for 30 min/three times daily in the morning, noon, and evening immediately after recovery from anesthesia and in Postpartum Department; while subjects in the control group followed the hospital routine care. Each woman in both groups was tested abdominally using a stethoscope to auscultate the bowel sounds and asked to report immediately the time of either passing flatus or stool. Results: illustrated that a highly statistically significant difference was observed between the two groups concerning their gum chewing outcomes. Where, P = 0.000. The study concluded that gum chewing is safe, well tolerated and appears to be effective in reducing the incidence and consequences of POI following CS.

AbstractObjectivesObjective of the study is to investigate whether Soft tissue mobilization (STM) can assist with static stretching to improve hamstring flexibly.MethodsThe design of the study was repeated measure design. The study was conducted at the physical therapy laboratory of Jamia Hamdard University, New Delhi. Participants included 78 healthy males with hamstring tightness, randomly assigned to either the control group (static stretching) or the experimental group (STM and static stretching). The experimental group received five sets of four different STM techniques, followed by two sets of 30-s static stretches 3 days per week over the course of 12 weeks. The control group received 5 min of sham ultrasound with an inactive probe prior to static stretching. Active knee extension test (AKE) was the outcome measure.ResultsBoth groups showed significant improvement in AKE compared with the baseline measurements. With ingroup analysis showed a significant difference in AKE across all measured time periods (weeks 4, 8, and 12) with pre-test in both groups (p<0.05). No significant difference in AKE improvement was found between groups (p>0.05).ConclusionThe results of this study show that STM prior to static stretching does not significantly improve hamstring flexibility among healthy individuals. Although this study cannot be generalized, the results may be useful for evidence-based practice in the management of hamstring tightness.

Abstract Background Gestational diabetes is the most common medical complication in pregnancy, and it has many side effects for the mother and the fetus. The aim of this study was to evaluate the effect of oat bran consumption on gestational diabetes. Methods This study is a randomized clinical trial that was performed on 112 women with gestational diabetes treated with diet. Participants were randomly divided into two groups of 56. Participants in both groups were given a diet for gestational diabetes. In addition to the diet, the intervention group received 30 g of oat bran daily for 4 weeks at lunch and dinner. Tests of fasting blood glucose and two-hour postprandial (2hpp) glucose were taken from both groups: before the intervention, and 2 and 4 weeks after the start of the intervention. Data analysis was performed using SPSS statistical software (version 22) using independent t-test, as well as Chi-square and Mann-Whitney tests. P values less than 0.05 were considered statistically significant. Results There was no statistically significant difference between the two groups in terms of mean blood glucose before the intervention, while 2 and 4 weeks after the intervention, mean fasting blood glucose and two-hour postprandial (2hpp) glucose decreased significantly in the intervention group compared with the control group (P < 0.001). Conclusion Based on the results of this study, the addition of oat bran to the standard diet for pregnant women with gestational diabetes reduced fasting blood glucose and two-hour postprandial (2hpp) glucose. More detailed studies with higher sample sizes are recommended to prove the effectiveness of this valuable dietary supplement. Trial registration IRCT registration number:IRCT20191220045828N1.

Background: Mangosteen and propolis extracts (MAEC) have been potential therapeutic agents known to exhibit powerful antioxidant and anti-inflammatory properties. The aim of the current study was to evaluate the clinical and immunological efficacy of MAEC as well as safety and patient-reported outcomes (PROMs) on gingivitis and incipient periodontitis. Methods: This study was performed on 104 patients diagnosed with gingivitis or incipient periodontitis. At baseline, the participants were randomly allocated to either the test group, with daily intake of a single capsule containing 194 mg of MAEC for eight weeks, or control group, with placebo. Clinical periodontal evaluation and immunological parameters from saliva and gingival sulcular fluid were assessed at baseline, four, and eight weeks. Individual PROMs were assessed by OHIP-14 questionnaires. Results: There was a significant difference of modified gingival index at four and eight weeks between the test and control groups. In the test group, crevicular interleukin (IL)-6 was reduced, and the salivary matrix metalloproteinase (MMP)-9 was increased after eight weeks. PROMs were improved up to four weeks compared to placebo. Conclusion: Oral administration of MAEC would have a potential to reduce gingival inflammation clinically and immunologically in the patients with gingivitis and incipient periodontitis.
