Comparison of High Power Pain Threshold Ultrasound and Ischemic Compression Techniques for Treatment of Trigger Points
Study Details
Study Description
Brief Summary
This study aimed to compare the efficacy of ischemic compression and two different application methods of high power pain threshold ultrasound techniques on latent trigger point treatment. Asymptomatic subjects divided into three groups. First group took high power pain threshold ultrasound in which the intensity is kept constant at the pain level; second group took high power pain threshold ultrasound which the intensity is kept constant at half the pain level and third group took ischemic compression. All participants were asked to complete the questionnaires, which assessed pain, psychological factors and disability before treatment, after 1 week and 1 month follow-up. After each participants completed the questionnaire, the physical therapist evaluated the MTrPs. MTrPs assessment was performed before treatment, immediately after treatment, after 1 week and 1 month follow-up.

Detailed Description
Myofascial trigger points have been defined as discrete and hyperirritable areas located within a taut band of skeletal muscle or fascia which when compressed produce pain, tenderness, dysfunction and autonomic phenomena. The treatment techniques aimed to return the fiber groups affected by myofascial trigger points to their normal length and endplates to their normal function. Although both ischemic compression and two different application methods of high power pain threshold ultrasound techniques are effective methods in the treatment of trigger points , there are no studies showing which technique is more effective. It is aimed to to compare the efficacy of ischemic compression and two different application methods of high power pain threshold ultrasound techniques on myofascial trigger point treatment.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: high power pain threshold ultrasound which the dose was kept constant group (HPPT-US 1) Participants in HPPT-US 1 group received one session of HPPT-US treatment which the dose was kept constant. The technique delivers sound waves directly to the myofascial trigger points and results in immediate pain relief. |
Other: high power pain threshold ultrasound which the dose was kept constant
Participants in HPPT-US 1 group received the HPPT-US treatment. The intensity was gradually increased from 0.5 W/cm² to the pain threshold level at which the patient verbally reported the pain. The therapist kept the intensity at that level for 5 s, and then moved the US transducer in a circle without the change of the intensity for 15 s. The procedure was repeated 3 times. The patients were asked whether serious pain or any abnormal sensation was felt during HPPT-US. The intensity was varied from 0.5 to 1.2 W/ cm².

| Experimental: high power pain threshold ultrasound which the dose reduced to one half group (HPPT-US 2) Participants in HPPT-US 2 group received one session of HPPT-US treatment which the dose reduced to one half. The technique delivers sound waves directly to the myofascial trigger points and results in immediate pain relief. |
Other: high power pain threshold ultrasound which the dose reduced to one half
Participants in HPPT-US 2 group also received the HPPT-US treatment. The intensity was gradually increased from 0.5 W/cm² to the pain threshold level at which the patient verbally reported the pain. The therapist kept the intensity at that level for 5 s, then reduced the dose half and moved the US transducer in a circle for 15 s. The procedure was repeated 3 times. The patients were asked whether serious pain or any abnormal sensation was felt during HPPT-US. The intensity was varied from 0.5 to 1.2 W/ cm².
|
| Experimental: ischemic compression group Participants in IC group received one session of ischemic compression therapy. Ischemic compression is a therapy technique used in manual therapy, where blockage of blood in an area of the body is deliberately made, so that a resurgence of local blood flow will occur upon release. |
Other: ischemic compression
Participants in IC group received ischemic compression therapy. The technique was applied in the sitting position to participants. Ischemic compression was performed by compressing trigger points identified by palpation with tolerable intensity using thumb. The duration for each trigger points was 1 minute. Then the muscle containing the trigger point was applied intramuscular stretching for 30 seconds by therapist

Outcome Measures
Primary Outcome Measures
- Pain intensity [Pain intensity was measured using visual analog scale (VAS) before the treatment (0-10 numeric pain rating scale, with 0 indicating no pain and 10 severe pain)]
Pain intensity is of valuable diagnostic information, and we ask patients to evaluate how strong their pain feels
- Beck Depression Inventory [Depression was assessed using the Beck Depression Inventory (BDI) before the treatment. BDI comprises 21 items, each of which is rated between 0 and 3 on a 4-point Likert Scale. The total score ranges from 0 to 63 points.]
Depression is a constant feeling of sadness and loss of interest, which stops you doing your normal activities.
- Neck Pain and Disability Scale [Disability was evaluated by Neck Pain and Disability Scale (NPAD) before the treatment. The scale progresses from 0 to 5, increasing the limitation. the total NPAD score, which ranges from 0 to 100 points.]
A disability is any condition of the body or mind that makes it more difficult for the person with the condition to do certain activities (activity limitation) and interact with the world around them.
- Myofascial trigger points assessment [The MTrPs assesment was made with palpation by the physical therapist. The therapist used an algometer. The number of MTrPs and pain pressure threshold values were evaluated before treatment. PPT is a safe outcome measure to evaluate pain sensitivity.]
Myofascial trigger points (MTrPs) have been defined as discrete and hyperirritable areas located within a taut band of skeletal muscle or fascia which when compressed produce pain, tenderness, dysfunction and autonomic phenomena
- Myofascial trigger points assessment [The MTrPs assesment was made with palpation by the physical therapist. The therapist used an algometer. The number of MTrPs and pain pressure threshold values were evaluated immediately after the treatment.]
