Clinical Trial Summary

The purpose of the study is to compare between the efficacy of high intensity LASER therapy and scapular stabilization exercises on ventilatory functions in forward head posture patients

Description:

Neck pain is a common complaint in the population, with a considerable impact on individuals and their families, communities, health-care systems and businesses. The estimated 1-year incidence of neck pain ranges between 10.4 and 21.3%, and the overall prevalence of neck pain in general population can be as high as 86.8%.

The photothermic and the photochemical effects of high intensity LASER therapy may increase blood flow and stimulate collagen production within tendons; in addition, high intensity LASER therapy may increase vascular permeability and has an anti-inflammatory effect, thus removing the pain stimulus.

Scapular stabilization exercise is used as an effective way to recover the imbalance in posture and the muscles. It is also effective in increasing muscle activation in the serratus anterior and lower trapezius, through decreasing the compensatory movement, which is caused by the forward head posture, and in decreasing muscle activation on the upper trapezius. Furthermore, it brings about a spinal curve change and upper crossed syndrome improvement.

Therefore, this study will compare the difference between the effect of high intensity laser therapy and scapular stabilization as a modality of treatment on ventilatory function in forward head posture patients.

Related Conditions & MeSH terms

• Forward Head Posture

Intervention

Other:
• Postural advice
The patients received advice about maintaining good posture when sitting, standing, reading, driving, or lifting; taking breaks; sleeping on back or side with a pillow supporting head/neck; avoiding prolonged phone use; adjusting car seat; reading stand for upright posture; keeping objects close when lifting; and using pillows for support when breastfeeding.
• Traditional exercise treatment
The exercise program included strengthening of deep flexor muscles and shoulder retractors while stretching of cervical extensors and pectoral muscles.
• Scapular stabilization exercises
Scapular Stabilization exercise was composed of four exercise programs, including scapula retraction exercise, scapula mobilization exercise, and scapula dynamic stabilization exercise I and II.
• High intensity Laser therapy
There were two phases in every session, the wavelength is 1064 nm, size of spacer is 60 mm in both phases: Phase I (analgesic phase): the application was made by moving the applicator perpendicular to the skin in continuous circular movements at trigger points detected by acupuncture, power was 8.00 w with a dosage of 5 J/cm2, surface area 50 cm2, frequency 25 HZ, treatment time in this phase was 3 minutes and total energy received at this phase was 250 J. Phase II (bio stimulation): the application was made at the pain inflicting region by using continuous linear movements and prevent static application, The power was 8.00 w with a continuous frequency, dosage of 50 J/cm2, surface area 50 cm2, treatment time in this phase was 5 minutes and the total energy that was delivered to the patient during this phase was 2500 J.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Forced vital capacity (FVC)	It was assessed by a spirometer before and after treatment. The patient was asked to breath 3 tidal breaths then fully expire, then take a deep inspiration to expire forcefully and rapidly as much as possible through the mouthpiece, the procedure was repeated 3 times and the best record was taken.	12 weeks
Primary	Forced expiratory volume at one second (FEV1)	It was assessed by a spirometer before and after treatment. The patient was asked to breath 3 tidal breaths then fully expire, then take a deep inspiration to expire forcefully and rapidly as much as possible through the mouthpiece, the procedure was repeated 3 times and the best record was taken.	12 weeks
Primary	FEV1/FVC	The ratio between the forced expiratory volume at one second (FEV1) and forced vital capacity (FVC) was calculated before and after treatment.	12 weeks
Primary	Maximum voluntary ventilation (MVV)	It was assessed by a spirometer before and after treatment. The patients were instructed to breathe rapidly and deeply for 15 to 30 seconds, ventilatory volumes were recorded, and the maximal volume achieved over 15 consecutive seconds was expressed in liters per minute.	12 weeks
Primary	Craniovertebral angle (CVA)	It was measured by a specific goniometer that was positioned parallel to the C7 Spinous process and the goniometer's movable arm on the anterior cartilage of the ear. The angle between the movable arm and the perpendicular line passing through the C7 vertebrae was recorded.	12 weeks
Primary	Neck Disability Index (NDI)	It is a ten-item questionnaire that was used to assess disability associated with neck pain and whiplash. There are four items that relate to subjective symptomatology (pain intensity, headache, concentration, sleeping) and six items that relate to activities of daily living (lifting, work, driving, recreation, personal care, reading).	12 weeks
Secondary	Upper thoracic chest expansion	It was measured using a tape measure at the axillary level before and after treatment.	12 weeks
Secondary	Middle thoracic chest expansion	It was measured using a tape measure at the nipple level before and after treatment.	12 weeks
Secondary	Lower thoracic chest expansion	It was measured using a tape measure at the level of the tip of the xiphoid process before and after treatment.	12 weeks
Secondary	Visual analogue scale (VAS)	It was used to assess neck pain intensity; it is graded scale from 10 to 0 at one point along the length of a 10-cm line that represents a continuum between the two ends of the scale "no pain" on the left end (0 cm) of the scale and the "worst pain" on the right end of the scale (10 cm).	12 weeks
