Study summary

A randomized clinical trial aiming to assess the effect of cervical traction, using different loads, on balance parameters among patients with common cervical radiculopathy.

Authors hypothesized that as cervical traction alleviate radicular pain and improve function it may also improve patient balance parameters. Three different loads of traction are compared Main outcome measures are balance parameters (clinical and stabilometric). Patients are followed for during six months.

Read the detailed description

A randomized clinical trial was designed to assess the effect of cervical intermittent traction on balance parameters among patients diagnosed with common cervical neuropathy. The diagnosis is confirmed or made by a physical medicine and rehabilitation physician with 15 Y of experience treating musculoskeletal disorders especially cervical neuropathy. Enrolled patients are randomly assigned to one of three groups (A, B and C). Patients are treated with 2 Kg load intermittent cervical traction (A), 8 kg (B) and 12 kg (C). Patients in the three groups are treated additionnally with 12 rehabilitation sessions. Patients are assessed at baseline, at the end of the treatment (1 month), and at 3 and 6 months. Outcomes are mainly clinical balance assessment and stabilometry, and secondary, epidemiological parameters, pain intensity (VAS), cervical spine ROM and proprioception, grip strength, cervical spinal muscle strength, functional status (NDI), the psychological distress (HAD), and Quality of life All parameters are assessed at the Three follow-up points.

Study arms

  • Sham comparator
    Group A

    Patients in group A recieved cervical traction with 2 kg load combined with standard rehabilitation program. This group is condidered as sham because the 2 kg load does not have any effect on anatomical structures of the cervical spine.

    Other: Cervical traction · Other: Rehabilitation

  • Active comparator
    Group B

    Patients in group B recieved cervical traction with 8 kg load combined with standard rehabilitation program. The traction load in this group has an effect on muscular structures of the cervical spine without any actual effect on the remaining anatomical structures (intervertabral disks, joints and ligaments).

    Other: Cervical traction · Other: Rehabilitation

  • Experimental
    Group C

    Patients in group C recieved cervical traction with 12 kg load combined with standard rehabilitation program. The traction load in this group has an actual effect on muscles, intervertabral disks, joints, and ligaments of the cervical spine.

    Other: Cervical traction · Other: Rehabilitation

Interventions

  • OtherCervical traction

    Cervical traction procedure was performed using Saunders device. During the procedure, the patient lies in installed in a supine position with 20 degrees of cervical flexion and the physiotherapist gradually increases (5 minutes) the load to the defined kilograms which is maintained for 10 minutes then progressively decreases (5 minutes) the load to zero kilograms. The procedure is performed twice with a rest interval of 5 minutes.

    Also known as: Mechanical intermittent cervical traction

  • OtherRehabilitation

    The rehabilitation program compiled cervical spine mobilization, stretching of neck muscles and isometric strengthening exercises. Passive stretching of neck muscles groups was carried-out in a seated position with 3 repetition of 30 seconds each. Isometric strengthening exercises of neck extensors were performed in a seated position, against the resistance of the physiotherapist hand for 3 repetitions of 10 seconds each

  10. • Body Mass Index

    • Body Mass Index (BMI) (kg/m²)

    Time frame: Baseline.

  11. Cervical range of motion (ROM)

    Cervical ROM was measured using the Cervical Range-of-Motion Instrument (CROM; Performance Attainment Associates, St Paul, MN). With its three inclinometers, the CROM device is a useful clinical instrument for measuring the cervical spine's active mobility in flexion, extension, rotation, and lateral flexion.

    Time frame: Up to 6 months.

  12. Cervical proprioception

    Cervical proprioception was assessed using the CROM device. Patient wearing a CROM device is instructed to maintain a neutral head position while sitting (reference position). Patient is asked to close his eyes and move his head passively before returning it to the reference position by the examiner. The angle inaccuracy is measured in degrees by the examiner. The flexion and extension tests are run .

    Time frame: Up to 6 months.

  13. Cervical muscles strength

    Cervical muscles strength was measured using a handheld isometric dynamometer (MicroFET2; Hoggan Health Industries). Measurements were reported in Newton. To assess the strength of the flexor muscles, the dynamometer is placed on the forehead, while for the extensor muscles, it is placed at the back of the head

    Time frame: Up to 6 months.

  14. Handgrip strength (HGS)

    HGS was measured using the Jamar hydraulic handheld dynamometer (Lafayette Instrument Company, USA) and was reported in kilograms.

    Time frame: Up to 6 months.

  15. Neck disability assessment

    The Neck disability index (NDI), a reliable instrument used in clinical practice, was used to assess patients' activities of daily living . It includes 10 items (pain intensity, personal care, lifting, reading, headaches, concentration, work status, driving, sleeping and recreation) each scored from 0 (no disability) to 5 (total disability). The total score is 50 , a higher score indicates a higher disability. The NDI is expressed by percentage. The Arabic version of NDI was delivered to patients.

    Time frame: Up to 6 months.

  16. Psychological status assessment

    The anxiety and depression profiles were assessed using the Hospital Anxiety and Depression scale (HAD). A validated Arabic version of the scale was used. The HAD includes 14 items (7 for anxiety and 7 for depression) rated from 0 to 3 each. The maximum score is 21 for each symptom, and a higher score indicates a poor psychological status . A score less than 7 indicates no depression or anxiety, a score of 8-10 indicates doubtful cases, and a score higher than 11 indicates a certain symptomatology.

    Time frame: Up to 6 months.

  17. Quality of life (QoL)

    The participants' QoL was assessed using the World Health Organization quality of life (WHOQOL-BREF) questionnaire with 4 domains: physical health, psychological, social relationships, and environment. Each domain is reported in percentages, with a higher score indicating better QoL, and a lower score indicating poor QoL.

    Time frame: Up to 6 months.

  18. Kinesiophobia assessment

    The Tampa Scale for Kinesiophobia (TSK) was used to evaluate the kinesiphobia. An Arabic version was administered to patients. The TSK includes 17 items rated from 1 to 4 each, with a total score ranging from 17 to 68. Higher scores reflect greater levels of movement-related fear, and a score higher than 37 indicates the presence of kinesiophobia.

    Time frame: Baseline.

Ran from Feb 2023 to primary completion in Jun 2023, 4 months.

Of 215 non-industry interventional studies with no phase under Radiculopathy, half reached primary completion within 12 months of starting (the median), counting those still running; a quarter within 5 and three quarters within 45. This study's 4 months is below that.

Counting every sponsor, half of 225 studies reached it within 12 months; a quarter within 5 and three quarters within 48.

Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Dec 11, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
