About this study

Official title: Conditioned Pain Modulation Effects of Manual Therapy in University Students With Recurrent or Chronic Neck Pain

The purpose of this study is to evaluate the effects of provoking pain with manual therapy on pain processing in university students with recurrent or chronic neck pain.

Read the detailed description

The mechanical stimulus produced in manual therapy (MT) techniques elicits neurophysiological responses within the peripheral and central nervous system responsible for pain inhibition. Almost all types of MT elicit a neurophysiological response that is associated with the descending pain modulation circuit. But it has not been demonstrated whether this inhibition occurs through a conditioned pain modulation mechanism generated by the pain that manual therapy techniques may elicit in the patient.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Manual TherapyOther

    • Postero-anterior mobilizations: the physiotherapist will place his thumbs on the posterior surface of the spinous process of the vertebra previously assessed as the most painful to mobilise. The oscillations will be performed at the frequency of 1 oscillation per second and will be performed 3 series of 3 minutes, with a 1 minute rest interval.
    • Pressure: The point of greatest pain shall be treated by maintained pressure in each of the following areas: right upper trapezius, left upper trapezius, right paravertebral musculature and left paravertebral musculature. Pressure shall be applied to each of the points for 1 minute.
    • Massage: Pressure is applied to the muscles by sliding along the muscle belly. This will be done slowly to control the pain that is being provoked. 3 minutes will be carried out on each upper trapezius, sliding from the acromion to the occipital and another 3 minutes on the paravertebral musculature on each side, sliding from T1 to the occipital.
Study groups in NCT05680688
Study groupRoleWhat they receive
Painful Manual TherapyExperimentalManual therapy treatment shall be carried out at a high intensity that causes pain to the patient. The aim is to provoke a medium intensity pain to the patient of 5/10 in the NRS. The physiotherapist will ask every 30 seconds the pain provoked by the treatment with the numeric rating scale (NRS) and the patient will give continuous feedback. Based on this, the physiotherapist will adapt the intensity of the treatment to provoke a medium intensity pain.
Receives: Other: Manual Therapy
Painless Manual TherapyActive comparatorManual therapy treatment shall be performed at a low intensity that does not cause pain to the patient. The aim is for the patient to report a pain intensity of 0/10 in NRS throughout treatment. The physiotherapist will ask every 30 seconds the pain provoked by the treatment with NRS and the patient will give continuous feedback. Based on this, the physiotherapist will adapt the intensity of the treatment to be performed below the pain threshold.
Receives: Other: Manual Therapy

What is being measured

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

  1. Change from Baseline in Tibialis Anterior Pressure Pain Threshold (PPT) to immediate post-intervention

    PPTs will be assessed bilaterally (the mean between both sides will be used for analysis) over the tibialis anterior muscle (remote pain-free area) using a digital algometer (Wagner instruments, Greenwich, CT, USA). Participants will be instructed to say "stop" when the pressure sensation becomes painful. The average of two trials for each side will be performed for analysis. The algometer pressure for assessment will be gradually increased at a rate of 1kg/second. Data will be collected in kg/cm2.

    Measured: At baseline and immediately after the intervention

  2. Change from Baseline in extensor carpi ulnaris PPT to immediate post-intervention

    PPTs will be assessed bilaterally (the mean between both sides will be used for analysis) over the extensor carpi ulnaris muscle (remote pain-free area) using a digital algometer (Model FPX, Wagner instruments, Greenwich, CT, USA). Participants will be instructed to say "stop" when the pressure sensation becomes painful. The average of two trials for each side will be performed for analysis. The algometer pressure for assessment will be gradually increased at a rate of 1kg/second. Data will be collected in kg/cm2.

    Measured: At baseline and immediately after the intervention

  3. Change from Baseline in upper trapezius PPT to immediate post-intervention

    Measured: 7 days after the intervention

  12. Change from Baseline in Parallel Conditioned Pain Modulation (CPM) to immediate post-intervention

    To evaluate conditioned pain modulation (CPM), a handheld pressure algometer will be used as the test stimulus to evaluate the PPT at the nail bed of the thumb of the symptomatic side before and during application of a conditioning stimulus. Ischemic muscle pain will be used as the conditioning stimulus using a sphygmomanometer. The sphygmomanometer will be applied around the upper arm of the asymptomatic side, with its lower rim 3 cm proximal to the cubital fossa. The cuff was inflated to 260 mmHg and maintained until the subject perceived a 7/10 pain on the NRS. The CPM will be the result of the PPT during the conditioning stimulus minus the PPT before the conditioning stimulus.

    Measured: At baseline and immediately after the intervention

  13. Change from Baseline in Sequential Conditioned Pain Modulation (CPM) to immediate post-intervention

    To evaluate conditioned pain modulation (CPM), a handheld pressure algometer (Model FPX, Wagner instruments, Greenwich, CT, USA) will be used as the test stimulus to evaluate the PPT at the nail bed of the thumb of the symptomatic side before and 1 minute after application of a conditioning stimulus. Ischemic muscle pain will be used as the conditioning stimulus using a sphygmomanometer. The sphygmomanometer will be applied around the upper arm of the asymptomatic side, with its lower rim 3 cm proximal to the cubital fossa. The cuff was inflated to 260 mmHg and maintained until the subject perceived a 7/10 pain on the NRS. The CPM will be the result of the PPT after the conditioning stimulus minus the PPT before the conditioning stimulus.

    Measured: At baseline and immediately after the intervention

  14. Change from Baseline in Termporal Summation of Pain (TSP) to immediate post-intervention

    TSP will be elicited with 10 applications of the algometer (Model FPX, Wagner instruments, Greenwich, CT, USA) at the individual PPT intensity perceived at the nail bed of the thumb of the asymptomatic side. For each pulse, the pressure will be increased at a rate of approximately 2 kg/second to the previously determined PPT intensity. Pulses will be presented with an interstimulus interval of 1 second because this has previously been shown to be optimal for inducing TSP with pressure pain. Before application of the first pressure pulse, subjects were instructed to manually rate the pain intensity of the first and 10th pulse with a NRS. The TSP will be calculated as the difference between the pain intensity of the tenth stimulus minus the first stimulus.

    Measured: At baseline and immediately after the intervention

  15. Change from Baseline in Cold Pain Intensity to immediate post-intervention

    Cold pain intensity will be evaluated with the subject resting on a chair with the ice application test. Testing will be conducted on the anterior skin of the right forearm.

    For the ice application test, the ice pack will be held on the skin for 10 s. After 10 s of ice application, subjects will be instructed to rate the intensity of pain on NRS. The procedure will be repeated three times to obtain a mean value, with a 60 s rest period between measures to avoid summation of pain.

    Measured: At baseline and immediately after the intervention
