Carpal tunnel syndrom during pregnancy (CTS) is a commonly overlooked problem by healthcare practitioners. It presents as mild to severe pain, numbness and sometimes weakness in the hands, wrists and forearms along the distribution of the median nerve. At times, the muscles in the forearm ache due to compensations in movement or activity that may result. The pain can occur at night, further disrupting sleep patterns. These symptoms may arise due to postural changes, increased edema, occupational stressors, or a combination of these. Often patients are told their symptoms will resolve after delivery. Although this is usually the case, patients can perform a few simple exercises that may ease or even eliminate this pregnancy complaint.
CTS due to edema tends to worsen during the third trimester, and often occurs bilaterally. (Turgut, et al 2001). Since edema worsens when the upper extremity is placed in a gravitydependent position, instructing your patient to elevate her arms is a good place to start. Rolling an ice cube over the wrist, called ice massage, can also reduce local swelling.
Exercises to improve flexibility may provide additional relief. Specific areas to include are the postural muscles as well as wrist and elbow.
Doorway Stretch: Hold onto doorframe as pictured above for 30 seconds. Perform 3 repetitions 2-3 times daily.
Wrist flexor stretch: Pull fingers back as shown. Hold a gentle stretch for 30 seconds. Perform 3 repetitions, 2-3 times daily.
Resting posture of the wrists should also be given consideration. At night, some women have the tendency to curl their wrists into a flexed position. Since they are sleeping, the best way to ensure their wrists stay in a neutral position is through the use of wrist splints. The ideal splint would have stays to keep the wrist from moving into flexion or extension, thereby keeping it in a neutral position. As an inexpensive alternative, some women are able to prevent the flexed wrist posture by sleeping with a pillow between their hands to prevent carpal tunnel syndrom during pregnancy.
