BOS 3701 Industrial ErgonomicsUnit VI AssessmentQUESTION 1Explain carpal tunnel syndrome. What structures are involved, and what pathologyexists here? Recommend prevention tips and treatments for this syndrome. Explainthe modified Allen test and Tinel's sign.Your response should be 200 words.Carpal Tunnel Syndrome: the term carpal tunnel is a medical term for the space inthe wrist where nerves and tendons pass from the forearm into the hand. Carpus isa word derived from the Greek word "karpos" which means "wrist." The wrist issurrounded by a band of ligament tissue that normally functions as a support for thejoint and creates a capsule. The tight space between this fibrous band and the wristbone is called the carpal tunnel. Knowing the structure of the hand helps understandwhy keeping the wrist straight while performing tasks is important. Looking closely,you can see that the median nerve lies just under the transverse carpal ligament.The nerve can be easily compressed or strained because it is just below a softstructure and subject to direct pressure from contact stress and internal pressurefrom awkward postures. The median nerve innervates the thumb and the first threefingers of the hand. The nerve transmits signals to and from the hand. If the mediannerve is damaged, the sensation and strength of the hand is often compromised orlost. (Stack, Ostrom, & Wilhelmsen, 2016, pg. 305)Treat carpal tunnel syndrome as early as possible after symptoms start. Take morefrequent breaks to rest your hands. Avoid activities that worsen symptoms andapply cold packs to reduce swelling also may help. Other treatment options includewrist splinting, medications and surgery. Splinting and other conservativetreatments are more likely to help if you've had only mild to moderate symptomsfor less than 10 months. (Mayo Clinic)Lifestyle and home remedies/steps may provide temporary symptom relief. Takeshort breaks from repetitive activities involving the use of your hands. Lose weightif you are overweight or obese. Rotate your wrists and stretch your palms andfingers. Take a pain reliever, such as aspirin, ibuprofen (Advil, Motrin IB, others) ornaproxen sodium (Aleve). Wear a snug, not tight, wrist splint at night. You can findthese over-the-counter at most drugstores or pharmacies. Avoid sleeping on yourhands. If pain, numbness or weakness recurs and persists, see your doctor. (MayoClinic)Allen test: The blood supply to your hand normally comes from two arteries fromyour wrist: the radial artery inner (thumb side of the wrist) and the ulnar artery(little finger side of your wrist). During your hand exam the physician will makesure that both arteries are open and working correctly. A simple physical test calledthe Allen test may be used to find out if the blood flow to your hand is normal. For
