Details and patient eligibility

About

The proposed project seeks to evaluate the influence of cervicothoracic (CT) manipulation and passive stretching to the upper trapezius on pressure pain thresholds and range of motion (ROM) in individuals without recent complain of neck pain.

2. History of neck whiplash injury
3. Diagnosis from your physician of cervical spinal stenosis (narrowing of spinal canal) or presence of symptoms (pain, pins and needles, numbness) down both arms
4. Presence of central nervous system involvement such as exaggerated reflexes, changes in sensation in the hands, muscle wasting in the hands, impaired sensation of the face, altered taste, and presence of abnormal reflexes
5. Evidence of neurological signs consistent with nerve root entrapment (pinched nerve in the neck)
6. Prior surgery to your neck or upper back

90 participants in 3 patient groups

Cervicothoracic manipulation

Active Comparator group

Description:

Description of a Right C7/T1 manipulation. The subject will lie prone. The therapist will stand on the L side of the subject facing in a cephalic direction (towards the patient's head). The therapist's right hand makes contact with the thumb on the right side of the spinous process of the first thoracic vertebra. The therapist left hand supports the head making contact on the temporal bone. The hand/neck is gently laterally flexed to the right, until slight tension is palpated in the tissues. A high-velocity low-amplitude thrust will be applied towards the subjects left side. If cavitation does not occur (an audible pop) the subject will be repositioned and the manipulation attempted a second time. A maximum of 2 attempts will be performed for each side of the neck.

Treatment:

Other: Cervicothoracic manipulation

Upper trapezius stretch

Active Comparator group

Description:

The subjects will be in a supine position. A researcher will passively place the subject's head into flexion, side-bending away and rotation towards the side to be stretched until the muscle barrier is met. The researcher will depress the subject's shoulder with 100 Newtons of force measured with a Micro FET pressure dynamometer (Hoggan Health Industries, Salt Lake City, UT).) Once this pressure amount is achieved the stretch will be held for 30 seconds. This will be repeated two times on each side. The subject will be asked to provide continuous feedback about the stretch felt and the degree of discomfort (if any) felt during the 30 second stretches.

Treatment:

Other: Upper Trapezius Stretch

Control group

Other group

Description:

Subjects assigned to the control group will receive no intervention. They will stay behind the curtained research area for approximately 3 minutes in a seated position.

Treatment:

Other: No intervention
