Brief Summary:
A prospective cohort follow-up study design is undertaken. Both males and females with mild to moderate carpal tunnel syndrome will receive standard-of-care wrist splint for 6 weeks and undergo follow up studies for data collection. Controls will also be seen for a one time visit.

Study Type : Observational
Actual Enrollment : 213 participants
Observational Model: Case-Control
Time Perspective: Prospective
Official Title: High Resolution Ultrasonographic Measurements of the Median Nerve Before and After Wrist Splinting for Carpal Tunnel Syndrome
Study Start Date : January 2014
Actual Primary Completion Date : November 2016
Actual Study Completion Date : November 2016

Primary Outcome Measures :
  1. Cross sectional area of median nerve using ultrasound [ Time Frame: 6 weeks ]

Secondary Outcome Measures :
  1. Patient-reported outcome measures using NeuroQOL and CTSAQ [ Time Frame: 6 weeks ]
  2. Motor latency, motor amplitude, sensory velocity and sensory amplitude with electrodiagnostic study [ Time Frame: 6 weeks ]
  3. cross sectional area, electrodiagnostic study, age, gender, height, weight, BMI, wrist circumference, wrist width. smoking and handedness as predictors of improvement (or no improvement) in the NeuroQOL and CTSAQ-measured clinical severity scale. [ Time Frame: 6 weeks ]

Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   Yes
Sampling Method:   Probability Sample
Study Population
Those with diagnosis of carpal tunnel syndrome, and healthy control subjects with no symptoms of CTS.

Inclusion Criteria:

  • 18 years or older and;
  • Diagnosis of mild to moderate CTS with median motor latency at 8 cm is greater than 4.5 milliseconds or Combined Sensory Index > 0.9 where first line therapy is indicated to include nocturnal wrist bracing
  • Control subjects without symptoms of carpal tunnel syndrome.

Exclusion Criteria:

  • Evidence of severe CTS as seen with electromyographic changes in the body of the muscle
  • Untreated hypothyroidism, Rheumatologic disorders
  • Diagnosed Severe CTS or Chronic symptoms of carpal tunnel, greater than 1 year, this includes wasting of the hand muscles
  • Undergoing or previously treated for carpal tunnel on affected side. This includes surgery (carpal tunnel release), corticosteroid injections, bracing within the last 3 months while wearing the brace consistently every night, or any other intervention.
  • Currently pregnant or < 3 months post partum
  • History of wrist, hand fracture or severe trauma to affected hand and/or wrist
  • Known tumor, mass or deformity of the hand/wrist
  • Inflammatory articular disease of the joints or tendons Existing cervical radiculopathy or previous surgeries to the neck for radicular symptoms
  • History of electrodiagnostic evidence of generalized polyneuropathy or evidence of denervation
  • Diagnosed neuromuscular disorders which may complicate CTS diagnosis
  • Implanted electronic device (pacemaker, intrathecal pump/stimulator)
  • Any illness that makes it unsafe for the patient to participate in the study
  • Not fluent in English as NeuroQOL and other subjective information is limited to the English language interpretation
