Brief Summary:
Deep dry needling of active myofascial trigger points of trapezius muscle is effective in the dimminution of pain of patients

Condition or disease Intervention/treatment Phase
Myofascial Trigger Point Pain Other: Group 1. Deep dry needling Other: group 2. Passive analitical stretch (performed in both groups) Not Applicable

Detailed Description:

EVALUATION:

A blind assesor does a complete evaluation of the patients to determine if they take part of the study. An assesment of pain (by visual analogue scale), Pain pressure theshold (kg/cm2 by algometry, Range of motion (CROM goniometer in degrees) and strength (digital dinamometry in Newtons) are performed. In this evaluation inclusion criteria is checked too.

INTERVENTION:

-TREATMENT GROUP(Deep dry needling group (DDN)):

An experienced physical therapist performed this treatment. The intervention included DDN of every active MTrP found in the trapezius muscle using a 4 cm x 0.32 mm acupuncture needle with guided tube. ). In the case of upper trapezius active MTrPs, DDN was performed in the prone position. For medium and lower trapezius muscle MTrPs, DDN was performed in a side-lying position as described by Simons et al. (Simons et al., 1999). Once the needle was inserted into the MTrP previously marked by the blinded assessor, local twitch responses (LTRs) were obtained by using Hong's fast-in and fast-out technique, which involves rapid movements of the needle in and out of the MTrP.

After that, the stretch is performed

- Passive stretch of the trapezius muscle (both groups)

Another experienced physical therapist, after taking part of training-sesions to do the same stretch as in DDN group, performed the stretch.Participants in this group received the same stretch as patients in treatment group.

Arm Intervention/treatment
Active Comparator: Deep dry needling
The group of DDN receive this treatment and stretch
Other: Group 1. Deep dry needling
Deep dry needling and stretch. The intervention included DDN of every active MTrP found in the trapezius muscle using a 4 cm x 0.32 mm acupuncture needle as described by Simons et al. (Simons et al., 1999). Once the needle was inserted into the MTrP previously marked by the blinded assessor, local twitch responses (LTRs) were obtained by using Hong's fast-in and fast-out technique, which involves rapid movements of the needle in and out of the MTrP. After four LTRs, the needle was withdrawn and the area was disinfected with alcohol again (Simons et al., 1999). Then, passive stretch was performed on the trapezius muscle.

muscle stretch
The stretch applied was as described by Simons et al. (Simons et al., 1999). During the stretch the physiotherapist took up the slack, avoiding pain elicitation, maintaining the tension for four seconds and releasing the tension for eight seconds; this cycle was repeated three times
Other: Group 1. Deep dry needling
Deep dry needling and stretch. The intervention included DDN of every active MTrP found in the trapezius muscle using a 4 cm x 0.32 mm acupuncture needle as described by Simons et al. (Simons et al., 1999). Once the needle was inserted into the MTrP previously marked by the blinded assessor, local twitch responses (LTRs) were obtained by using Hong's fast-in and fast-out technique, which involves rapid movements of the needle in and out of the MTrP. After four LTRs, the needle was withdrawn and the area was disinfected with alcohol again (Simons et al., 1999). Then, passive stretch was performed on the trapezius muscle.

Other: group 2. Passive analitical stretch (performed in both groups)
Other Name: only the same stretch as performed in deep dry needling group.




Primary Outcome Measures :
  1. Subjective Pain scored by Visual Analogue Scale (VAS.Participants were followed for the duration of the intervention, an average of 6 weeks) [ Time Frame: pretreatment, postreatment and follow-up(15 days) ]
    pretreatment = at baseline; post-treatment= after 5 physical therapy sessions, 3 weeks after baseline; follow-up= 15 days after last intervention.


Secondary Outcome Measures :
  1. Pain Pressure Threshold (PPT. Participants were followed for the duration of the intervention, an average of 6 weeks) [ Time Frame: Pretreatment, post treatment and follow-up. ]
    pretreatment = at baseline; post-treatment= after 5 physical therapy sessions, 3 weeks after baseline; follow-up= 15 days after last intervention.


Other Outcome Measures:
  1. Strenght scored by Digital dynamometer (Participants were followed for the duration of the intervention, an average of 6 weeks) [ Time Frame: Pretreatment, post treatment and follow-up. ]
    pretreatment = at baseline; post-treatment= after 5 physical therapy sessions, 3 weeks after baseline; follow-up= 15 days after last intervention.

  2. Cervical Range of Motion assesed with CROM goniometer (Participants were followed for the duration of the intervention, an average of 6 weeks) [ Time Frame: Pretreatment, post treatment and follow-up. ]
    pretreatment = at baseline; post-treatment= after 5 physical therapy sessions, 3 weeks after baseline; follow-up= 15 days after last intervention. Participants were followed for the duration of the intervention, an average of 6 weeks)
