Brief Summary

The study will be determine how muscle energy strategy for the upper trapezius and sternocleidomastoid muscles affects the craniovertebral angle and shoulder angle.

Conditions

Forward Head Posture

Outcome Measures

Primary Outcomes (3)

• craniovertebral angle

  (CVA): It is the angle formed between a horizontal line through the spinous process of C7 and a line from the tragus of the ear It is a measure of forward head posture

  one month

• shoulder angle

  (SA) : is formed at a line between the center of the humerus and spinous process of C7 and the horizontal line through the center of the humerus. It is a measure of rounded shoulder posture.

  one month

• Pressure Pain Threshold

  the point at which a non-painful pressure stimulus turns into a painful pressure sensation Subjects' pressure pain thresholds (PPTs) were assessed using a Commander algometer

  one month

treatment group

EXPERIMENTAL

(30) thirty patients with forward head received PIR for upper trapezius and sternocleidomastoid muscles. the therapist moved the subject's head into the position that put each muscle in stretch, once resistance/ barrier was felt, that position was held and subjects were asked to isometrically contract the target muscle with 20% of maximal contraction for 5 sec against mild resistance from the therapist, relax for 5 sec followed by passive stretch until reaching a new barrier for 30 sec, 3 repetitions for each muscle, 3sessions /week over a period of 4 weeks In addition to the program designed for control group.

Other: exersice program (Muscle energy technique); Other: exersice program (stretching and strengthening exercises ) In addition to postural advices

control group

SHAM COMPARATOR

(30) thirty patients with forward head received static stretching exercise for upper trapezius and sternocleidomastoid . Repetitions: 3times/day, 3days/week over a period of 4 weeks, in addition to strengthening exercises of deep cervical flexors and scapular retractor muscles 3sets of 12 repetitions with 6 sec hold. In addition to postural advices

Other: exersice program (stretching and strengthening exercises ) In addition to postural advices

Study Design

• Study Type: interventional
• Phase: not applicable
• Allocation: RANDOMIZED
• Masking: SINGLE
• Who Masked: PARTICIPANT
• Masking Details: with computer generated block. Participants were randomized in blocks of 4 with a 1:1 allocation ratio to reduce the bias and variability between the two groups. The randomization was generated by an author who was not entailed in data collection. Randomization codes were kept confidential in sealed opaque envelopes and sequentially numbered to ensure concealed allocation.
