• Conditions: Shoulder Impingement

• Registration Number: NCT06998615
• Lead Sponsor: Cairo University

Brief Summary

this study will be conducted to evaluate the correlation between shoulder impingement and cervical proprioception

Detailed Description

Shoulder pain is one of the most common complaints in musculoskeletal practice, whether it comes from impingement syndrome or a defect in rotator cuff muscles .Shoulder pain is considered to be the third most common complaint in musculoskeletal practice, with a prevalence of 7% to 34% .Shoulder impingement is a syndrome where there is entrapment of soft tissue through the shoulder joint, with a prevalence of 44% to 65% of all shoulder complaints. Shoulder impingement has multiple causes, whether functional, degenerative, and anatomical and mechanical causes .Shoulder impingement classified to primary and secondary. Secondary impingement is subdivided into internal and external impingement .Proprioception components are joint position sense, kinesthesia, sense of force, sense of change of velocity. joint position sense is our perception of position of the joint or limb it divided to active/passive joint position sense, it means that the person can relocate the position of the joint or the limb to the same position after the joint or limb is moved.the muscle receptor helping in identifying the limb position and movement through changeling in neural signaling in the sensory receptor, giving the neurological control and basis of proprioception to sensory receptors located in the skin, muscles, and joints, so the proprioception is considered to be a loop of feedforward and feedback signals between sensory receptor and the nervous system. sixty eight subjects with shoulder impingement syndrome will be joined to this study.

Primary Outcome Measures

Name	Time	Method
joint position error (cervical proprioception)	up to thirty minutes	neck proprioception by Joint Position Error (JPE) using LASER beam Point tool and it's conducted as patient sitting 90 cm away from the target map on the wall ad a light weight headband with laser pointer is placed on the patient head, the patient is asked to focus on the center of the map while eye open then the patient asked to close his eyes and move his head in one plane and back to the starting point as accurately as possible and indicate verbally that he back to the starting position before opening his eyes, he repeated for 6 times in each plane and the distance between the starting point and the ending point is measured and then converted to degrees the patient is diagnosed to has a proprioception deficit if the mean error of any direction in more than 4.5 degrees
shoulder disablity	up to thirty minutes	The Shoulder Pain and Disability Index (SPADI) is a self-administered questionnaire that consists of two dimensions, one for pain and the other for functional activities. The pain dimension consists of five questions regarding the severity of an individual's pain. Functional activities are assessed with eight questions designed to measure the degree of difficulty an individual has with various activities of daily living that require upper-extremity use.he pain scale is summed up to a total of 50 while the disability scale sums up to 80. The total SPADI score is expressed as a percentage. A score of 0 indicates best 100 indicates worst.
pain intensity	up to thirty minutes	Pain will be assed with numerical analog scale (NPRS) in which a respondent selects a whole number (0-10 cm) that best reflects the intensity of his/her pain. 0 mean no pain and 10 mean maximum pain
