简要总结
The purpose of this study is to investigate the effects of myofascial decompression (cupping) and neurodynamic sliding technique for the hamstring on Division I Track and Field athletes who complain of hamstring tightness. Research questions will be: how do these techniques affect hamstring range of motion and flexibility; isometric strength of the hamstring muscle; muscle activation; and rate of force development. The hypotheses of this study are that neurodynamic sliding will have an effect on all variables and myofascial decompression will only have an effect on range of motion.
详细描述
Predisposing factors to hamstring injury include neural tension and muscle flexibility restrictions due to fascial adhesions. The sciatic nerve can produce symptoms of pain, decreased range of motion, and increased resting muscle tone when it is overstretched. The nerve can be overstretched after a hamstring injury and cause adhesions on the nerve and abnormal mechanosensitivity leading to perceived hamstring tightness.The purpose of this study is to investigate the effects of myofascial decompression (cupping) and neurodynamic sliding technique for the hamstring on Division I Track and Field athletes who complain of hamstring tightness.

研究组 & 干预措施
Neurodynamic Sliding
neurodynamic sliding consists of 2 movements; 1) movement 1 involves sitting on the edge of the treatment table the bringing their neck to their chest along with bending their knee and pointing their ankle to the ground. Movement 2 is performed by facing their head towards the ceiling and straightening their knee while pointing their ankle towards their nose. Subjects will alternate these 2 active movements for 60s and repeated 5 times, with rest period of 15s between sets.
干预措施: Neurodynamic Sliding (Other)
Myofascial Decompression
For the group receiving the cupping treatment, the subject will lay on their stomach and their affected hamstring will be exposed. Cocoa butter will be applied to the hamstring prior to the application of the cups. 5 cups will be placed along the hamstring and calf muscles. Using a handheld suction pump, each cup will be pumped so that skin fills up half of the cup. The cups will stay in place for five minutes and the clinician will instruct the subject to perform 5 repetitions of active quad sets and 5 repetitions of ankle pumps .
干预措施: Myofascial Decompression (Other)
Diathermy
The control group will receive a sham heat (diathermy treatment). The subjects will be asked to sit and relax for five minutes and the machine will not be turned on with a timer timing the treatment.

结局指标
主要结局
Hamstring Flexibility change
时间窗: Baseline, 5 minutes after intervention, and within 24 hours of intervention
Using the 'Active Knee Extension test', subjects are placed supine with both the hip and knee positioned at 90° of flexion and then asked to extend lower leg until point of limitation. A digital inclinometer is used to measure the angle of the knee joint in this position to examine flexibility of the hamstring muscle group.
次要结局
- Electromyographic (EMG) Muscle Activation of the Hamstring muscles(Baseline, 5 minutes after intervention, and within 24 hours of intervention)
- Hamstring muscle strength change(Baseline, 5 minutes after intervention, and within 24 hours of intervention)
- Disablement of the Physically Active patient outcome survey(Baseline, 5 minutes after intervention, and within 24 hours of intervention)
- Functional Patient Outcome survey(Baseline, 5 minutes after intervention, and within 24 hours of intervention)
- Time of Force Development(Baseline, 5 minutes after intervention, and within 24 hours of intervention)
