Carpal Tunnel Syndrome and Hand Positions

5 Jun

The wrist is very flexible, and the reason the wrist is so supple is because it’s made up of eight small carpal bones that are lined up in two rows of four bones each. Along with the transverse carpal ligament, these rows of carpal bones form an actual tunnel in which nine muscle tendons (and their sheaths) and the median nerve pass. If inflammation or swelling occurs that reduces the space in the carpal tunnel, then the median nerve can become compressed and restricted, which stimulates the various symptoms commonly linked to carpal tunnel syndrome (CTS). Another factor that can limit space in the carpal tunnel has to do with hand positions.

In a 2023 study, researcher utilized high-frequency, diagnostic ultrasound (HFDU) to specifically look at median nerve position changes and cross-sectional area of the nerve when the wrist is bent upward (dorsiflexion) and downward (palmar flexion) in 85 patients (110 affected hands) diagnosed with mild (n=38), moderate (n=30) and severe (n=42) CTS as well as 25 healthy control subjects (50 hands). Compared with the control wrists, the CTS-affected wrists exhibited much greater median nerve compression against the floor of the tunnel (the transverse carpal ligament) in both bent wrist positions. The researchers also used a diagnostic technology called nerve conduction velocity to confirm that this compression at the end-ranges of wrist flexion and extension are associated with dysfunction of the median nerve.

While this finding is interesting, it just reinforces what many healthcare providers already know about CTS: symptoms worsen at the end ranges of motion, and prolonged, awkward wrist postures should be avoided. That’s why one of the most common tools used to manage CTS is a nocturnal wrist splint to prevent the wrist from bending during sleep. However, it’s generally not recommended to wear a wrist splint at all times as immobilization could lead to deconditioning of the muscles in the region and worsen the patient’s situation.

In addition to avoiding prolonged bending of the wrists, CTS patients are also instructed to try to keep the wrist in a neutral position, take frequent breaks, and avoid high vibration exposure when performing hands-on work or hobby-related tasks because it can increase inflammation in the carpal tunnel and exacerbate symptoms and slow recovery. 

Successful management of CTS may also involve addressing non-musculoskeletal factors that can promote inflammation or swelling in the wrist, such as diabetes. Patients may also receive advice on inflammation-promoting foods to avoid or supplements to take to reduce inflammation in the body. Your chiropractor will also assess the full course of the median nerve starting at the neck to make sure there are no other areas in which the nerve’s motion is restricted since it’s not uncommon for this to occur in multiple sites.

Conservative Chiropractic Care for Carpal Tunnel Syndrome

10 May

Carpal tunnel syndrome (CTS) is a condition the occurs when mobility of the median nerve is restricted as it passes through the wrist, resulting in symptoms that extend into parts of the hand including pain, numbness, tingling, and weakness. Generally, symptoms come on gradually but worsen and become more frequent over time. While most often associated with computer work, CTS can affect anyone whose work involves repetitive hand movements—especially when combined with non-neutral wrist postures or vibration exposure—or who is affected by conditions that create swelling or inflammation in the wrist tissues, such as pregnancy, obesity, diabetes, rheumatoid arthritis, and more. There are many treatment options available to the CTS patient, of which chiropractic care is highly favored both by patients and the clinical treatment guidelines.

When the CTS patient first presents for chiropractic treatment, they will complete a patient history that describes both their current symptoms as well as any other health conditions they’ve had in the past or are currently experiencing. In addition to letting the doctor of chiropractic know if there are health conditions that may contribute to CTS and may require co-treatment to achieve a successful resolution, the history will also indicate the potential for conditions that can co-occur with CTS or be mistaken for it, such as median nerve compression elsewhere along the course of the median nerve or compression of another nerve that innervates other parts of the hand, such as the ulnar nerve. With this information, the chiropractor will conduct an examination to better understand the patient’s unique situation, which may include diagnostic imaging, such as X-ray. At this point, they can confirm a diagnosis and decide upon a treatment approach.

Treatment will typically include a combination of in-office therapies and at-home instruction. In-office treatment will primarily involve manual therapies, such as manipulation, mobilization, and soft tissue work, to increase mobility of the median nerve as it passes through the wrist as well as elsewhere along the course of the nerve’s course if multiple entrapments are present. In-office treatment may also include modalities such as cold laser, e-stim, pulsed electromagnetic field, and more. 

Between visits, patients may be advised to wear a wrist splint at night or during some activities, though not all the time, to help keep the wrist in a neutral position that takes pressure off the median nerve. They may also be instructed on exercises or stretches they can perform several times a day and/or receive instruction to take supplements or modify their diet to reduce inflammation. 

While several studies support these conservative treatment approaches for managing CTS, it’s important to note they work best early in the course of the disease. The longer a patient waits to seek care, the more time it may take to achieve a satisfactory outcome. In severe cases, the only option may be surgical intervention. If you’re currently dealing with bothersome symptoms in the hand and wrist, don’t just shake your hand and carry on. Contact your doctor of chiropractic and schedule an evaluation.

Pre-Surgical Treatment for Carpal Tunnel Syndrome 

10 Apr

Outside of an emergency situation, such as a wrist fracture, treatment guidelines for carpal tunnel syndrome generally recommend exhausting non-surgical options before consulting with a surgeon. But how well are guidelines followed? To find out, researchers surveyed 770 members of the American Society for Surgery of the Hand to better understand the current practice patterns regarding the non-surgical care for CTS patients. Roughly half of respondents had two decades or more of experience in the field with 80% completing a residency in orthopedic surgery and 81% either currently have or previously had a subspecialty in hand surgery.

According to the survey, 72.9% of the CTS patients the surgeons consulted with had previously had two or more corticosteroid injections with 41.2% of surgeons recommending an additional injection before recommending surgery. About four-in-five surgeons did not believe oral steroids are effective for managing CTS though they are included in clinical treatment guidelines developed by the American Academy of Orthopedic Surgery (AAOS). The authors of the study note there is a lack of feedback to the patient’s primary care doctor (and other authorities) when these approaches fail, which may perpetuate their use unnecessarily. 

The researchers point out that the current AAOS clinical treatment guidelines cite strong evidence to support corticosteroid injections and moderate evidence that oral steroids could improve patient-reported outcomes compared to placebo. The study authors continue by noting a study that found corticosteroid injections may only provide short-term benefits compared to a placebo, and another study that concluded a second corticosteroid injections may not offer additional benefit. 

The survey results appear to be contrary to the guidelines put forth by the AAOS, which may be misguiding primary care and general orthopedic physicians. The authors conclude that their findings highlight the importance of better implementation of non-surgical CTS treatment strategies that follow current evidence-based information, rather than following the clinical practice guidelines of the AAOS.

The good news is that the various treatments provided by doctors of chiropractic are highly effective in managing mild-to-moderate CTS as studies have demonstrated that such conservative therapies can be as effective as surgery over the long-term with fewer adverse events.

Difficultly in Carpal Tunnel Syndrome Management

20 Mar

Carpal tunnel syndrome (CTS) can be a complex condition that can be a challenge to manage for several reasons.

  • There can be multiple contributing causes. Seldom is CTS the result of one traumatic event, like a broken wrist that produces instant symptoms that requires emergency surgical treatment. Rather, the condition tends to develop over time as the result of an accumulation of microtraumas that affect the tissues in the carpal tunnel and place pressure on the median nerve and hamper its mobility. To complicate matters even more, conditions like hypothyroidism, pregnancy, obesity, and the use of birth control pills can also affect the function of the median nerve, either directly or indirectly through swelling/inflammation.
  • Median nerve entrapment elsewhere. The median nerve originates in the cervical spine and travels from the neck to the shoulder and down the arm. Compression anywhere along the path of the nerve can stimulate CTS-like symptoms. Additionally, entrapment of the median nerve elsewhere on its course can often co-occur with entrapment at the wrist.
  • It might not be carpal tunnel syndrome. While we commonly associate symptoms in the hand and fingers with CTS, there are two additional nerves—the radial and ulnar—that innervate other parts of the hand and fingers. Radial and ulnar nerve entrapment can also co-occur with CTS.
  • Work can be the cause. Occupational exposure to vibration, repetitive movements, infrequent breaks, and awkward wrist postures can each increase the risk for CTS. It may not be possible for the patient to change how they perform their work, which can make recovery difficult. 
  • Some factors can’t be controlled. Women are three times more likely to develop CTS than men, which is believed to be due to females having a narrower carpal tunnel and possibly hormonal differences compared with males. The risk for CTS also increases with age. 
  • Patients often wait too long. Because CTS symptoms come on gradually, it’s easy to ignore them, and a patient may not seek care until their symptoms become so bothersome or severe that they simply can’t maintain their usual activities. Unfortunately, the longer a patient waits, the longer it may take to achieve a satisfactory resolution. In some cases, a full resolution may not be possible or surgery may be the only viable option. 

The good news is that chiropractic care can be an effective intervention for managing CTS, especially if you seek care sooner rather than later. If necessary, your doctor of chiropractic will co-manage the case with an allied healthcare provider to give you the best possible chance at recovery.

Carpal Tunnel Syndrome Diagnosis

8 Jul

Despite being the most common entrapment neuropathy (pinched nerve) in the extremities, a gold-standard test for diagnosing carpal tunnel syndrome (CTS) has yet to be established. In part, this is due to how the symptoms develop from patient to patient, as well as the presence of other conditions that can result in a similar collection of symptoms. So when a patient presents with suspected CTS, how does their doctor of chiropractic determine if it’s CTS or something else?

The most useful starting point is a review of the patient’s history, which can reveal factors that point to the possibility of carpal tunnel syndrome, such as a job that requires forceful gripping of heavy tools. On the other hand, if a patient has a history of neck pain or whiplash, then it would make sense to evaluate the neck as a possible source of median nerve entrapment or the history may point to potential contributing factors, such as hormonal issues, that may require co-management with another healthcare professional.

Patients may also complete a CTS-specific questionnaire to collect data on the symptoms they’re experiencing, the location of the symptoms, and the intensity of the symptoms (typically on a 0-10 scale where 0=no pain and 10=excruciating pain).

The subsequent examination will follow the course of the median nerve to determine if there is pressure on multiple sites. At this point, a doctor of chiropractic may have a fairly strong suspicion on what is causing the patient’s symptoms, and he or she can formulate a treatment recommendation.

However, if the case is complicated, the patient may be referred for more advanced testing—like electrodiagnostic testing—to confirm the diagnosis. Because these tests can be unpleasant and painful to the patient and there is up to a 34% possibility for a false positive, it may sometimes be more useful to inform a diagnosis rather than as the initial means to make a diagnosis.  This was confirmed by a 2018 study that concluded that electrodiagnostic testing is not a reliable screening method for determining the severity of CTS.

During the course of care, patients may also be asked to complete short assessments, such as the Boston CTS Questionnaire (BCTSQ) that includes eleven questions (scored 1-5 for “normal” to “very severe”) for symptoms and eight questions for function (scored 1-5 for “no difficulty” to “cannot perform the activity at all due to hand and wrist symptoms”). Not only does this information help track a patient’s progress to determine if the treatment plan needs modification but it can be used to prove “medical necessity” to the patient’s insurance company.

The Hip-Foot Connection

15 Jun

When examining a patient for hip pain and other musculoskeletal conditions, doctors of chiropractic will expand their focus beyond the area of chief complaint to identify issues elsewhere in the body that may be underlying or contributing factors. This is especially true with the hip because anything that affects normal locomotion can lead to compensatory changes and abnormal motion in the hip joint, which can easily result in inflammation or wear and tear that causes pain. Such is the case with issues in the foot, like plantar fasciitis.

Plantar fasciitis is one of the most common causes of heel pain and is characterized by inflammation of the thick band of tissue (plantar fascia) located on the bottom of the foot that connects the heel bone (calcaneus) to the toes. Individuals with the condition may experience a stabbing pain that often occurs with initial weightbearing, especially in the morning. The intense initial pain usually improves after a few steps; however, it can also worsen following prolonged standing or intense activity.

The function of the medial longitudinal arch of the foot is to absorb shock and to add “spring” to each step. In the mid-stance phase of gait, the arch flattens out, stretching the plantar fascia (the “string”) and if stress and tension exceeds the tissue’s threshold or becomes too great, micro-tears inflame the fascia and cause pain when initiating weightbearing. This leads to pain and can affect normal gait, which can ultimately lead to issues up the kinetic chain, such as hip pain.

Risk factors for PF include advancing age, stressful exercise (running, ballet dancing, aerobic dance), altered arches in the feet (such as flat feet as well as a high arch), obesity, and occupations that require an individual to be on their feet all day, especially on hard surfaces.

Following diagnosis, which may include a review of the patient history and an examination, a conservative treatment approach in a chiropractic setting may include manual therapies (longitudinal and cross fiber friction massage); Graston technique (using spoon-like tools to stimulate blood flow and break up adhesions); stretching exercises (calf stretches off a step or using TheraBand to bend the foot and ankle upwards and extend the toes); prescription foot orthotics with pronation correction (lateral heel wedge); modalities (laser, ultrasound, extracorporeal shock wave therapy); and dorsiflexion night splinting. Patients may also be encouraged to reduce their intake of processed foods—which can increase inflammation in the body—and eat a more anti-inflammatory diet, like the Mediterranean diet, to aid in the healing process.

Because prolonged standing and stressful exercise can worsen the condition, patients may be advised to reduce the time they spend on their feet and switch to less impactful forms of exercise during recovery. The good news is that conservative treatment approaches, such as chiropractic care, are often successful in helping PF patients manage their condition.
