Filter by:The aim of this study is to build on previous published work, which has indicated lumbar mobilisations have the ability to increase hamstring extensibility and decrease muscle activity. The primary aim of this project is investigate if lumbar mobilisations have an affect on the Nordic Hamstring exercise. Aim: To investigate the short-term effects L4 and L5 Unilateral Posterior Anterior (UPA) Mobilisations on the lumbar spine on the Nordic Hamstring Exercise. Measures will include hamstring peak torque, sEMG activity and knee angle at first rapid change in angular acceleration.
This study aimed to compare the effect of two hamstring strengthening programmes on hamstring muscle strength in Gaelic footballers. 26 Gaelic footballers were recruited and randomly assigned to one of two 4-week hamstring strengthening programmes, namely the hip extension exercise programme and the Nordic hamstring exercise protocol. Isokinetic hamstring and quadriceps strength were measured before and after the intervention.
This study evaluates the injury in amateur football, adding different excercise into the habitual practice. There are three groups, one of them do eccentric excercise, another group doing proprioception exercise and the last group don´t do any exercise.
Few studies indicate that sprint performance may be impaired in football players with a previous hamstring strain injury. This exploratory cross-sectional study aim to compare sprint performance between football players with and without a previous hamstring strain injury. The findings may elucidate potential indications of insufficient rehabilitation following a hamstring strain injury. Sprint performance data will be collected using the MySprint Iphone Application. Due to pragmatic reasons and the exploratory nature of this study the aim is to include players on a team level. Based on the prevalence of hamstring strain injuries the expected number of cases to be included are 10-20 football players with a previous hamstring strain injury, and a corresponding 80-90 number of healthy controls. No outcomes will be weighted (flat outcome structure).
To compare the immediate and short-term effects of L4 and L5 Unilateral Posterior Anterior (UPA) Mobilisations on the lumbar and hamstring range of motion and EMG activity of the Erector Spinae and Hamstring muscles. Using a pre-test post-test crossover design subjects lumbar flexion and active knee extension with be recorded prior to and following unilateral zygapophyseal joint mobilisations. Measures will be taken immediately after and then 5, 10, 15, 20, 30 and 60 minutes intervals post intervention. Mobilisation force will be measured via force plates to ensure consistent mobilisation pressure. Following data collection statistical analysis will be undertaken to analyse any potential benefit of lumbar mobilisations to influence the EMG activity of the Erector Spinae and Hamstrings. Functional assessment of lumbar range of motion and hamstring range of motion to be conducted and analyse any effect on movement
Purpose: To conduct a pilot study of the effect of Cranial Laser Reflex Technique (CLRT) compared with sham laser on hamstring muscle flexibility, strength, and pain pressure threshold. Participants: Active, young adults ages 18 to 35. Procedures: A two-visit, assessor and participant-blinded crossover study with 1-week washout. Subjects will complete three functional hamstring tests before and after CLRT and sham laser treatment. Subjects will also complete questionnaires to assess their expectations and perceptions of the interventions.
The goal of this study is to determine safety and tolerability of Losartan when used for treatment of an acute grade II or III hamstring strain and determining the effect of losartan on recovery of hamstring muscle function. Subjects will be adults age 18 and older with grade 2 or 3 hamstring injury who participate in greater than 100 hours per year in Level 1 or Level 2 athletics or have a similar activities or physical work load (e.g. military personnel). Subjects will undergo examination, MRI, and functional assessment before, during, and after 4 weeks of losartan (50mg QD) or placebo.
