It Isn’t Always Carpal Tunnel Syndrome

When symptoms such as pain, tingling, numbness, and weakness affect the hand, the first
condition that comes to mind for most people is carpal tunnel syndrome (CTS). While CTS is the
most common nerve entrapment affecting the upper extremity, it is far from the only possible cause
of these symptoms. So how does a chiropractor determine whether the problem is CTS or something
else?
The process begins with the patient completing a detailed health history that addresses both
current symptoms and relevant medical background. This information helps determine whether
compression of the median nerve—central to a CTS diagnosis—is likely, or whether one of the other
nerves supplying the hand should be considered. During the physical examination, the chiropractor
performs specific provocative tests to help identify where the median nerve—or another nerve—may
be restricted along its course. In some cases, though not routinely required, additional diagnostic
tools such as nerve conduction studies or ultrasound may be used to help confirm the diagnosis.
If symptoms primarily involve the thumb, index finger, middle finger, and the thumb-side of
the ring finger and are reproduced by wrist compression or sustained wrist positions, classic carpal
tunnel syndrome is likely. However, compression of the median nerve at other locations along its
pathway can produce a similar symptom pattern. Potential sites include the forearm, below or above
the elbow, the shoulder, and even the neck. To further complicate matters, nerve compression can
occur at multiple sites simultaneously. For example, a 2016 study found that approximately 1 in 16
patients with CTS also had median nerve compression in the forearm, a condition known as pronator
teres syndrome.
The ulnar nerve, which supplies sensation to the pinky and the ulnar side of the ring finger,
can also become compressed as it passes through a different anatomical structure at the wrist called
Guyon’s canal. As with the median nerve, restriction of the ulnar nerve anywhere along its course
from the neck to the hand can generate similar symptoms. The same principle applies to the radial
nerve, which innervates the back of the hand and can become irritated as it passes through the radial
tunnel near the wrist. This is why a thorough history and physical examination is so critical: the
history helps identify which nerve is involved and the examination helps pinpoint where compression
may be occurring.
In most cases, conditions involving median, ulnar, or radial nerve compression respond well
to a multimodal conservative treatment approach. This may include manual therapies such as
manipulation, mobilization, and soft tissue techniques; therapeutic exercises; nighttime bracing;
activity modification; and anti-inflammatory strategies. Importantly, outcomes are typically faster
and more favorable when patients seek care early, rather than waiting months or years before
consulting with a chiropractor.

must be done through the advice and counsel of a healthcare professional who is familiar with your updated medical history.
