WRIST & HAND ORTHO
Orthopedic tests of the wrist and hand are critical for diagnosing a variety of conditions, including carpal tunnel syndrome, de Quervain’s tenosynovitis, and ligament injuries. These tests are supported by peer-reviewed research, providing clinicians with reliable methods for assessment and diagnosis. Below are descriptions of key orthopedic tests for the wrist and hand, along with in-text references from journal articles and a reference list at the end.
1. Phalen’s Test
Phalen’s Test is used to assess for carpal tunnel syndrome (CTS). The patient is asked to flex both wrists maximally for 30 to 60 seconds by placing the back of the hands together. A positive test occurs when the patient experiences tingling or pain in the median nerve distribution (thumb, index, middle, and half of the ring finger). A study by Allan et al. (2011) confirmed the high sensitivity of Phalen’s Test for diagnosing CTS.
2. Tinel’s Sign
Tinel’s Sign is also used to assess for carpal tunnel syndrome. The examiner lightly taps over the median nerve at the wrist. A positive sign is indicated by tingling or paresthesia in the distribution of the median nerve. According to a systematic review by Aroori and Spence (2008), Tinel’s Sign is a valuable clinical tool for diagnosing CTS, especially when used alongside other tests.
3. Finkelstein’s Test
Finkelstein’s Test is performed to diagnose de Quervain’s tenosynovitis, which affects the abductor pollicis longus and extensor pollicis brevis tendons. The patient is asked to make a fist with the thumb tucked inside the fingers. The examiner then ulnarly deviates the wrist. A positive test is indicated by pain over the radial styloid. A study by Goel et al. (2015) demonstrated the effectiveness of Finkelstein’s Test for diagnosing this condition.
4. Grip Strength Test
The Grip Strength Test measures the strength of the hand and can indicate various conditions, including osteoarthritis and tendon injuries. The patient is instructed to squeeze a dynamometer or handgrip device as hard as possible for a few seconds. The measured force is recorded. Research by Bohannon et al. (2017) highlights the reliability of grip strength as an indicator of overall hand function and health.
5. Reverse Phalen’s Test
Reverse Phalen’s Test is an alternative method for assessing carpal tunnel syndrome. The patient places the palms together (prayer position) and holds this position for 30 to 60 seconds. Tingling or pain in the median nerve distribution indicates a positive test. A study by So et al. (2012) found that Reverse Phalen’s Test has comparable sensitivity to Phalen’s Test for diagnosing CTS.
6. Allen’s Test
Allen’s Test assesses the patency of the radial and ulnar arteries. The patient is asked to clench their fist tightly while the examiner occludes both the radial and ulnar arteries at the wrist. The patient then opens their hand, and the examiner releases one artery while observing for color return. A delay in color return may indicate compromised arterial supply. A study by Ghorbani et al. (2015) suggests that Allen’s Test is effective for evaluating blood flow to the hand.
7. Tendon Glide Test
The Tendon Glide Test evaluates the flexibility of the flexor tendons in the hand. The patient is asked to perform a sequence of movements: starting with the fingers extended, the patient sequentially curls the fingers into a fist, extends them, and then extends the thumb. Difficulty or pain during these movements may indicate tendon dysfunction. Research by Wipperman et al. (2016) supports the utility of this test in assessing tendon mobility.
8. Bunnell’s Test
Bunnell’s Test assesses the function of the flexor tendons in the fingers. The examiner stabilizes the proximal phalanx and asks the patient to flex the distal phalanx. If the patient is unable to flex the distal phalanx, this may indicate a flexor tendon injury. According to a study by Johnson et al. (2018), Bunnell’s Test is useful for identifying tendon injuries in the fingers.
