Brief Summary

effects of Instrument Assisted Soft Tissue Mobilization (IASTM) and Post-Isometric Relaxation (PIR) in reducing pain, improving range of motion, and enhancing function among individuals with trapezius myalgia. it was a randomized clinical trial with outcome measuring tools as NPRS for pain Goniometer for ROM NDI for function

Conditions

Trapezius Myalgia

Keywords

Instrument assisted soft tissue mobilization; post-isometric relaxation; Trapezius myalgia

Outcome Measures

Primary Outcomes (1)

• Numeric Pain Rating Scale

  The pain intensity was assessed using Numeric Pain Rating Scale (NPRS) an 11-point (0-10) tool used to measure a patient's pain intensity, where 0 means "no pain" and 10 means "the worst pain imaginable

  Baseline and after 6 weeks

Secondary Outcomes (2)

• Range of Motion

  Baseline and after 6 weeks

• Neck Disability Index

  baseline and after 6 weeks

Study Arms (2)

GROUP 1 (Intrument assisted soft tissue mobilization)

EXPERIMENTAL

IASTM (Members of this group received instrument-assisted soft tissue mobilization in addition to a standard intervention aimed at reducing pain and enhancing range of motion and functional ability.)

Other: IASTM

GROUP 2(Post isometric relaxation)

ACTIVE COMPARATOR

Post isometric relaxation(The members of this group underwent post-isometric relaxation combined with the same standard protocol, with the same goals of alleviating pain and improving mobility and function.)

Other: Post isometric relaxation

Interventions

IASTM OTHER

IASTM intervention was administered three times weekly for six weeks.

GROUP 1 (Intrument assisted soft tissue mobilization)

Post isometric relaxation OTHER

PIR intervention was administered three times weekly for six weeks.

GROUP 2(Post isometric relaxation)

Eligibility Criteria

• Age: 25 Years - 35 Years
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64)

You may qualify if:

• Individuals aged 25 to 35 experiencing trapezius myalgia,
• both men and women who report neck pain and stiffness,
• Limited range of motion in lateral neck bending and rotational movement.
• Presence of identifiable tender areas or trigger points within the trapezius muscle, Evidence of muscle tightness observed during mobility assessments, such as when performing lateral head tilt.
• A firm band of muscle tissue containing a hypersensitive point, often with a palpable nodule and potential for radiating discomfort.

You may not qualify if:

• Traumatic injury to the neck causing torticollis,
• Tumor affecting the upperportion of the trapezius muscle,
• Cervical nerverootirritation or damage, Break in one or more cervical vertebrae,
• Impairment of nervous system function,
• Swelling and hypersensitivity reactions in the skin,
• Abnormal spinal curvature and birth-related structural defects.

Study Design

• Study Type: interventional
• Phase: not applicable
• Allocation: RANDOMIZED
• Masking: SINGLE
• Who Masked: PARTICIPANT
• Masking Details: The study used a lottery-based randomization process to assign patients to two groups. Participants drew a sealed slip labeled either 1 or 2 from a box, determining their group allocation. Those who drew number 1 were assigned to Group A, and those who drew number 2 to Group B. This method ensured an equal, randomized distribution between the two groups. Both groups received interventions as part of an outpatient rehabilitation program
• Purpose: TREATMENT

Model Details: GroupA(InstrumentAssistedSoftTissueMobilizationTechniqueGroup) Members of this group received instrument-assisted soft tissue mobilization in addition to a standard intervention aimed at reducing pain and enhancing range of motion and functional ability. GroupB(PostIsometricRelaxationTechniqueGroup) The members of this group underwent post-isometric relaxation combined with the same standard protocol, with the same goals of alleviating pain and improving mobility and function.
