Brief Summary

• To evaluate the effects of a 32-weeks resistance and stretching training program applied in Physical Education classes on forward head and protracted shoulder Portuguese adolescents (15-17 years old).
• To evaluate on adolescents submitted to strength and stretching exercises the effects of a 16-week detraining period after the end of the intervention protocol.

Outcome Measures

Primary Outcomes (1)

• change in postural angles (cervical and shoulder angle)

  We will assess the Cervical angle - the angle formed at the intersection of a horizontal line through the spinous process of C7 and a line to the tragus of the ear and the shoulder angle - The angle formed at the intersection of the line between the midpoint of the humerus and the spinous process of C7 and the horizontal line through the midpoint of the humerus.

  36 and 48 weeks

Secondary Outcomes (1)

• the American Shoulder and Elbow Surgeons Standardized questionnaire

  36 and 48 weeks

Study Arms (2)

Interventional program

EXPERIMENTAL

The training protocol is constituted by 4 strengthening exercises (Side Lying External Rotation, Prone Horizontal Abduction with External Rotation, Y to I exercise and Chin Tuck) and 3 stretching exercises(one- Sided Unilateral Self Stretch Exercise, one-sided Unilateral Self Stretch Exercise, Static Sternocleidomastoid Stretch and Static Levator Scapulae Stretch

Other: Interventional program postural correction training

Control group

ACTIVE COMPARATOR

The control group will only participate in the Physical Education classes

Other: Control Group physical education classes

Interventions

Interventional program postural correction training OTHER

The postural correction training program was applied in the last 15-20 minutes of each PE class, twice a week, with the supervision and help of the PE teacher.

Interventional program

Control Group physical education classes OTHER

Only performed the physical education classes

Eligibility Criteria

• Age: 15 Years - 17 Years
• Sex: all
• Healthy Volunteers: No
• Age Groups: Child (0-17)

You may qualify if:

• adolescents with 15-17 years old with cervical angle lower than 50º and the shoulder angle lower than 52º

You may not qualify if:

• Participants were excluded if their CV and SH angle was equal or higher than 50º and 52º respectively, if they had visual deficits, diagnosed balance disorders, musculoskeletal pathologies, such as a history of shoulder surgery, cervical or thoracic fracture, were non-ambulatory, displayed functional or structural scoliosis, or had excessive thoracic kyphosis.
