Group 1 - The article discusses the common confusion between carpal tunnel syndrome and cervical spondylosis, emphasizing the importance of accurate diagnosis for effective treatment [1][3] - Carpal tunnel syndrome occurs when the carpal tunnel, which houses the median nerve and finger flexor tendons, becomes narrowed, leading to nerve compression and symptoms [2][3] - Cervical spondylosis, particularly the nerve root type, is prevalent, accounting for approximately 60%-70% of cervical spondylosis cases, and is caused by degenerative changes in the cervical spine [3][4] Group 2 - Symptoms of carpal tunnel syndrome include numbness in the thumb, index, middle, and part of the ring finger, with symptoms worsening at night or after prolonged use of the hand [4][3] - Symptoms of cervical spondylosis include neck stiffness and pain that radiates down the shoulder and arm, with potential for widespread numbness depending on which nerve is affected [4][10] - Self-assessment methods for both conditions are provided, including tapping the wrist for carpal tunnel syndrome and pressing down on the head for cervical issues, but these methods are not substitutes for professional diagnosis [7][9][10] Group 3 - The article highlights the need for timely medical consultation if symptoms persist for more than a week or if there is muscle weakness, urging early detection and treatment to avoid complications [13]

Core Viewpoint - The new version of the "Occupational Disease Classification and Directory" in China officially includes carpal tunnel syndrome, commonly known as "mouse hand," as a legally recognized occupational disease starting from August 1 [1] Group 1: Prevalence and Symptoms - The prevalence of "mouse hand" among video terminal workers in China is reported to be between 12% and 15% [1] - Symptoms include wrist pain and finger numbness, particularly affecting the thumb, index, middle, and half of the ring finger [2][5] - Women are at a higher risk due to narrower carpal tunnels and hormonal changes that may increase swelling [2] Group 2: Causes and Affected Professions - "Mouse hand" is closely related to repetitive wrist movements and excessive local pressure, not limited to office workers but also affecting drivers, assembly line workers, and musicians [3][4] - Activities such as playing musical instruments or household chores can also lead to the condition [4] Group 3: Self-Assessment and Misconceptions - Signs of "mouse hand" include increased numbness at night, decreased grip strength, and potential muscle atrophy at the base of the thumb [5] - A common misconception is that "mouse hand" is merely a strain that does not require treatment, which can lead to irreversible nerve damage if left unaddressed [6] Group 4: Treatment and Prevention - Early symptoms can be managed with stretching, heat therapy, and anti-inflammatory medications, while severe cases may require surgical intervention [7] - Two recommended preventive exercises include tendon gliding and median nerve sliding, which should be performed daily without causing numbness or pain [8]
