简要总结
controversy remains about the stretching parameters needed to achieve a particular goal or treatment outcome. In clinical practice, multiple stretching techniques are used; nevertheless, there is no evidence-based agreement on the most effective parameters. One of these parameters, that might be affecting the treatment outcome the most, is the stretching duration, thus far there is a little agreement on the optimal stretching duration.
This non agreement in exact stretching parameters is obvious between authors and researchers in the field of muscle energy techniques (MET) as well as those who have used and advocate various durations for the passive stretch that follows the contraction phase in MET.
详细描述
comparison and subsequent conclusions about appropriate stretching times are mainly based on mechanical factors such as range of motion and flexibility, while ignoring the neural adversative mechanical tension that may be created during stretching exercises. According to the literature , stretching induced neural tension may adversely affect the central nervous system and nerve root function due to the absence of the perineurium, which is the primary load carrying structure. Thus, safe or unsafe limits of nerve elongation are not well established, despite several basic scientific and clinical studies.. Consequently, in the present study, the current study aimed to answer the question: Is it theoretically possible, that increased longitudinal strain and stress on the spinal cord and nerve root from continuous stretching exercises may subtly impair the neural function? Our hypothesis is that a duration threshold exists where, once reached, adverse neural function will be apparent resulting in a reduction of either or both latency and amplitudes of evoked potentials.

The treating therapist, for both the control and intervention groups, was unblinded to the treatment method but the subjects and assessor who conducted the measurements were blinded. Assessor blinding was obtained through an independent research assist; not knowing the study design and not specifically involved in any aspect of the tria

- •have generalized neck pain for more than 3 months.
- •with symptoms provoked by neck postures, movements, or palpation
排除标准
- •Subjects' exclusion criteria included specific neck pain due to trauma, disc protrusion, whiplash, congenital deformity of the spine, spinal stenosis, neoplasm, inflammatory or rheumatic disease.

结局指标
主要结局
The change in peak-to-peak amplitudes of dermatomal somatosensory evoked potentials
时间窗: will be measured at two intervals ;pre-treatment and 24 Hours after treatment
Dermatomal Somatosensory Evoked Potentials will be elicited by repetitive, square wave (0.5 ms) electrical pulses (at 3 Hz) from standard clinical surface gel electrodes (20 mm) overlying cervical sensory dermatomes. Dermatomal somatosensory evoked potential will be collected at a stimulus intensity well above perception threshold.Complete recording runs will be undertaken during each session with averages of 250 to 1200 cortical responses from scalp surface recording electrodes (C3'-C4' in a 10-20 electrode configuration) of the contralateral scalp to the C4 to C8 dermatomes being stimulated
次要结局
- The change in Neck pain intensity(will be measured at two intervals ;pre-treatment and 24 Hours after treatment)
- The change in Cervical range of motion(will be measured at two intervals ;pre-treatment and 24 Hours after treatment)
- The change in Neck Disability Index(will be measured at two intervals ;pre-treatment and 24 Hours after treatment)
