“…However, both techniques improved the muscle length. A number of studies have compared different treatment methods such as HR and static stretch (15), diathermy and stretch (22), surface heat and stretch (17) and cyclic loading and hold relax (16), to increase the extensibility of short muscles. Their reports were similar and no significant differences were reported between the two methods, as we found in this study.…”

“…The process was repeated three times. The parameters of HR training were determined based on the previous studies which reported improvement of muscle length (15,25). The experimental groups undertook five weeks of the intervention program, while the control group carried out their normal activities of daily living.…”
Background: Shortness of skeletal muscles may cause musculoskeletal disorders of body; improvement of these muscles may improve posture and body function. Objectives: The aim of this study was to compare the effects of ultrasound (US) together with stretch and hold relax (HR) techniques in increasing the muscle length. Materials and Methods: It was a randomized trial with intention-to-treat analysis and assessor blinding. A total of 34 male students (18-24 years old) who had bilateral hamstring shortness (straight leg raise (SLR) < 65 degrees) were candidates for the study. Group one received US with stretching, group two received HR method and group three or control group did not receive any special treatment and had their normal daily living activities. Group one received stretching with 3 MHz continuous US (1.5 W/cm 2 ) for four minutes. Group two (HR) received four cycles of HR training including 20 seconds of contraction and 10 seconds of relaxation. The hamstring muscle was passively taken to the end of the range. The assessment methods included passive SLR and passive knee extension (PKE), using goniometry.
Results:The results of the study (SLR and PKE) indicated that the mean of range of motion( ROM ) in the two treatment groups increased significantly during the treatment period, compared to the control group. Comparison of the two treatment methods, US with stretch and HR, revealed that there was no significant difference between the two methods in terms of ROM in SLR and passive extension. Conclusions: The two treatment methods had similar effects and there were no significant difference between them, while significant improvement was seen in the experimental groups compared with the control group.

“…The hamstring muscle extensibility of both groups was improved. Puentedura, et al 11) reported that a method for knee joint extension in the supine position stretched the hamstring muscle. In the present study, the KES exercise group showed improvements in forward bending, active SLR angle and active extension of the knee joint.…”

“…There are various ways of recovering the extensibility of the hamstring muscle, including SLR, the muscle energy technique, knee joint extension exercise, proprioceptive neuromuscular facilitation, and the active release technique 2,3,[7][8][9][10][11] . Of these, the method most widely used for stretching the hamstring muscle is SLR.…”
Abstract.[Purpose] The purpose of this study was to determine the effect of a knee extension exercise in the sitting position (KES) on stretching of the hamstring muscles of patients who suffered from lower back pain. For this study, we compared the effect of the passive straight leg raise (SLR), an exercise already proven effective, with that of passive KES.[Subjects] Thirty-one subjects (18 males and 13 females) were randomly divided into two groups: one group received the passive KES exercise method, and the other group the passive straight leg raise exercise method.[Method] Forward bending, active SLR and active knee joint extension were measured before and after the two passive exercises.[Results] Forward bending, active SLR, and active knee joint extension improved in both groups. However, the KES exercise group showed greater improvement in forward bending than the SLR exercise group. Although both passive KES exercise and passive SLR exercise were effective at stretching the hamstring, passive KES exercise, which allows for stability of the lumbar spine, was more effective when motion required lumbopelvic rhythm. [Conclusion] On the basis of these results, we conclude that passive KES exercise is a more effective treatment for forward bending of patients with lower back pain.
“…There are papers approaching the joint mobility manifestation in relation with different stretching techniques, but they are usually addressed to adult persons and performance athletes (Feland, Myrer, & Merrill, 2001;Schuback, Hooper, & Salisbury, 2004;Yuktasir & Kaya, 2009;Puentedura et al, 2011).…”
The role of physical education is to act in order to increase the manifestation of motor ability indices among pupils. For this reason, the development of joint mobility in young pupils has a particular importance, by its limiting effects on the adjustments and designation of the movement easiness characterizing the ability of an element to move. The purpose of this paper was to make a diagnosis of the range of motion for the main joints, which included measurements of mobility in the scapular-humeral, coxofemoral and talocrural joints, in primary school pupils from Middle School No. 192. To achieve the intended purpose, it was initiated a comparative study conducted between December 2014 and January 2015, during 14 lessons (according to school schedule and curriculum). The subjects were 80 pupils from 1 st to 4 th grades, participants in the physical education and sports lesson. It was created a group of schoolboys and also a group of schoolgirls for each grade of the primary education, in total 4 groups of 10 schoolboys each and 4 groups of 10 schoolgirls each. Results were obtained using tests for the mobility or flexibility assessment, according to Brian Mackenzie, and through the statistical method, we calculated the arithmetic mean. Analysis of the results provides objective information about the level of mobility development in the subjects tested throughout their evolution.
