About this study

Official title: Chemotherapy - Induced Peripheral Neuropathy (CIPN). Could There be a Role for Physical Therapy Treatment?

The cause of Chemotherapy-Induced Peripheral Neuropathy (CIPN) is still unknown. An estimated 55-60% of patients will experience lasting symptoms affecting function for years post-treatment. Physical therapy is an established, effective treatment for entrapped nerves and neuropathic pain. This study sought to identify additional risk factors and provide evidence for the role of physical therapy in the treatment of CIPN.

Read the detailed description

A common side effect is chemotherapy induced peripheral neuropathy (CIPN). CIPN is a small fibre sensory neuropathy that develops in the hands/feet and worsens with increasing dose and duration of treatment. It impacts the Aβ, Aδ, and C-Fiber function involved in light touch and vibration sense, thermal detection and thermal pain. This results in a variety of positive and/or negative sensory symptoms including hypoesthesia, dysesthesias, hyperalgesia, allodynia and neuropathic pain. Quantitative sensory testing (QST) are a variety of non-invasive tests aimed at quantifying sensory perceptions used in research to clinically assess neuropathy. It is used for sensory detection and pain thresholds for both mechanical and thermal stimuli. QST provides information on large myelinated (Aβ), small thinly myelinated (Aδ) and unmyelinated (C-fiber) function or dysfunction. Deep pressure threshold measured by a pressure algometry stimulates intramuscular afferents, and can be used as a measure of central sensitization when used at a distant site from the site of pain. Aδ fibres transmit cool detection threshold, while warm detection threshold is transmitted by C-fibers. Both noxious heat and noxious cold transmit via C-fiber and Aδ fibers. An increased sensitivity to thermal pain thresholds, results in thermal hyperalgesia.

Physical therapy treatment for nerve disorders is well established in orthopedics and plastic surgery for entrapment neuropathies, neuropathic pain, post-operative nerve repair and regeneration. Nerve gliding exercises are frequently used exercises in physical therapy to improve neural excursion across joints, improve pain and decrease inflammation. Patient reported symptoms (patient questionnaires NPRS, S-LANSS and DASH) and quantitative sensory testing (QST) specifically pain pressure thresholds and vibration were used for the primary purpose in evaluating the role for an upper extremity nerve mobilization physical therapy home program during chemotherapy for the prevention and management of CIPN.

Primary Outcome Measures was the NPRS and reported as those having no vs no pain. Grip strength, Vibration, DASH and S-LANSS were identified outcome measures prior to the trial that would best describe sensory impairment and function for the physical therapy question

Additional QST measures collected included warm/cool, Hot/Cold Pain thresholds that were used with the vibration data to compare quantitative data on the right and left side to evaluate possible a possible dual nerve disorder when combined with surgery as well as identifying different sensory profiles of QST data between those reporting neuropathic pain and non-neuropathic pain using the S-LANSS

A sub analysis of data was completed dividing participants that remained active throughout compared to less active participants to evaluate the effect of exercise on sensory preservation. This was not an intended analysis at the beginning of the trial and these participants were not randomized.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Percentage of Participants With 'Pain' or 'no Pain' as Measured by the Numeric Pain Rating Scale

    Numeric Pain Rating Scale - pain rating scale 0-10 (0= no pain to 10= most pain imaginable). Reported as percentages of participants with pain (1-10) vs no pain (0)

    Measured: Regression models of pain reported over time (mid-docetaxel chemotherapy- 6 months post-chemotherapy). Mid-chemotherapy time frame participants were re-assessed after the 2 round of TC and 4th round of FECD.

  2. Disability of the Arm, Shoulder and Hand (DASH)

    A 30 item participant reported questionnaire commonly used to gauge upper limb function. Each item is scored 1-5 with 1 being 'no difficulty' and 5 being 'unable'. Overall score calculated as: [average response (sum of responses divided by number of responses) -1] x 25 to give a score out of 100. Minimum score is 30 with a maximum score of 150. The DASH was chosen because of high test-retest reliability and the responsiveness and construct validity in patients with breast cancer over other quality of life measures. A minimal clinical important difference is a change score of 15. Higher score indicates more impairment to the upper limb

    Measured: administered on each re-assessment (pre-chemotherapy, mid-way through docetaxel chemotherapy, end of chemotherapy, 6 months post-chemotherapy) and mixed models accounted for all time points

  3. Percentage of Participants With Neuropathic Pain Defined by the Self Report Version of Leeds Assessment for Neuropathic Symptoms and Signs (S-LANSS).

    a 7 item patient reported questionnaire and was used to confirm the presence of neuropathic pain. The score ranges from 0-19 (no symptoms=0, sever symptoms=19) with a score above 12 indicative of neuropathic pain/symptoms. S-LANSS was chosen because of its' specificity and accuracy in a cancer population. Participants were requested to answer specifically for the hands, not feet.

    Measured: administered on each re-assessment (Visit 1 - pre-chemotherapy, Visit 2 - half-way through chemotherapy, Visit 3 - end of chemotherapy, Visit 4 - 3 months post-chemotherapy) and mixed models accounted for all time points

Secondary outcomes (3)
  1. Vibration Sensory Analysis

    Vibration analysis testing for perception thresholds are specific to Aβ nerve fibres. The TSAII Vibration Sensory Analyzer (VSA): Medoc, Israel, was used. The pulp of the index finger lightly touches the sensor that delivers random and varying vibration amplitudes (µm). The participant responds "yes/no" to sensing the vibration. Vibration perception was selected for its sensitivity and has been suggested to be the first clinical sign of CIPN symptoms and was tested bilaterally. Low score indicates better perception while a higher score is poorer sensation. Perception score reported in micrometers (up to 4cm)

    Measured: administered on each re-assessment (Visit 1 - pre-chemotherapy, Visit 2 - half-way through chemotherapy, Visit 3 - end of chemotherapy, Visit 4 - 6 months post-chemotherapy) and mixed models accounted for all time points

  2. Pain Pressure Thresholds

    Pressure Algometry (Somedic AB, Sweden) measured pressure/pain thresholds. A hand-held device applied perpendicular to the muscles being tested. Increasing pressure is applied until the participant determines that the sensation has changed from a feeling of pressure to a feeling of pain and force (Kpa) is recorded. When tested at a distant site from the source of pain this test measures central sensitization. Lower pressure values (more sensitive to noxious stimuli) suggest impaired central pain and/or diminished descending inhibition pathway. The left quadriceps muscle was tested as a measure of central sensitization.

    Measured: administered on each re-assessment (Visit 1 - pre-chemotherapy, Visit 2 - half-way through chemotherapy, Visit 3 - end of chemotherapy, Visit 4 - 6 months post-chemotherapy) and mixed models accounted for all time points

  3. Grip Strength

    Hand Dynamometry records grip strength in kgs and was used as a measure of function (3 trials). The dominant hand was tested using the Jamar dynamometer (Patterson medical, USA) in the 2nd handle position. All 48 participants were right handed.

    Measured: administered on each re-assessment (Visit 1 - pre-chemotherapy, Visit 2 - half-way through chemotherapy, Visit 3 - end of chemotherapy, Visit 4 - 6 months post-chemotherapy) and mixed models accounted for all time points
