Treatment of RSI
identifying precipitating activity, modification of equipment or activity, pain management, rest, physical therapy for strengthing exercises, and lifestyle changes
Pain management in RSI
heat/cold applications, NSAIDs
CTS (acronym means...)
carpal tunnel syndrome
CTS (definition)
a condition caused by compression of the median nerve beneath the transverse carpal ligament within the narrow confines of the carpal tunnel located in the wrist

What type of anasthesia is used for surgical decompression in CTS?
regional anasthesia
Important consideration after CTS surgery
the neurovascular status of the hand should be evaluated before discharge
patient instruction after CTS surgery
patient should be instructed in the appropriate assessments at home
What is endoscopic carpal tunnel release
surgical procedure win which the decompression is performed through a small incision puncture site
What type of anasthesia is used in endoscopic carpal tunnel release?
another alternative surgical intervention for CTS
modified open carpal tunnel release procedure
What is the rotator cuff?
a complex of four muscles in the shoulder
what are the 4 muscles included in the rotator cuff?
supraspinatus, infraspinatus, teres minor, and subcapularis
what do the rotator cuff muscles to?
stabilize the humeral head in the glenoid fossa while assisting with the ROM of the houlder joint and rotation of the humerus
What are degenerative process of the rotator cuff associated with?
normal aging
How can a tear in the rotator cuff occur?
gradual, degenerative process resulting from aging, poor posture, repetitive stress(esp overhead movements), or use of an arm to break a fall
