Abstract
Background. A fault posture of head can disturb the body balance. Forward head posture (FHP) is one of common faulty postures seen among university students. Whole Body Vibration (WBV) is a quick method of neuromuscular training used to increase muscle strength, improve dynamic balance control and eventually correct posture.
Purpose. A randomized controlled trial was designed to investigate the effect of WBV training on craniovertebral angle and dynamic balance control in subjects with forward head posture.
Methods. Forty-five participants (11 males and 34 females, 18-23 years old) were randomly allocated into 3 equal groups: group (A) received traditional treatment (stretching and strengthening exercises) + postural advices, group (B) received whole body vibration training + postural advices, group (C) received traditional treatment + whole body vibration training + postural advices, 3 sessions /week for 4 weeks. Outcome measures included craniovertebral angle (CVA), overall stability index (OSI), anteroposterior stability index (APSI) and mediolateral stability index (MLSI) that were assessed at baseline and 4 weeks post-intervention.
Results.  Comparing all groups post training revealed that there were statistically significant increases (p < 0.05) in all measured variables (CVA, OSI, APSI and MLSI) in favour of group (C), while there were statistically non-significant differences between group A & B (p > 0.05).
Conclusion. The conjugation of WBV training with traditional treatment of FHP improved craniovertebral angle and dynamic balance control in subjects with forward head posture.

Abstract
Background. Mechanical neck pain (MNP) is one of the most common disorders that originates from poor postural habits and bad ergonomics. Forward head posture (FHP) was highly correlated to MNP. Muscle energy technique (MET) and stretching are easy widespread therapeutic techniques that are known for their effects in improving tissue extensibility, relieving pain and promoting function.
Objective. A randomized controlled trial was designed to compare the effect of MET versus static stretching in terms of FHP, pain and disability in patients with MNP.
Methods. Thirty participants (3 males and 27 females, 18-30 years old) were randomly allocated into one of 3 groups: group (A) received MET+ hydrocollator pack+ postural education, group (B) received stretching and strengthening exercises+ hydrocollator pack+ postural education, group (C) control group received hydrocollator pack+ postural education, 3 sessions /week for 4 weeks. Evaluation was done pre-treatment, post-treatment and after 6-weeks of follow-up. Results: There were significant improvement (p<0.05) in all tested variables in all groups post-treatment except disability in control group. There was significant improvement of pain in all groups, disability in experimental groups and FHP in stretching group only at the follow-up. There were no significant differences between groups in all measured variables.
Conclusion. MET has equal effect to that of static stretching regarding pain and function even after 6-weeks of follow-up. Stretching showed better improvement in FHP correction that persists. Postural education is effective in pain management and seems to have a role in preserving long-term outcome.

Abstract
Aim: to explore the effect of forward head posture (FHP) on temporomandibular joint (TMJ) proprioception in post-pubertal females.
Material and Method. Forty post-pubertal females participated in this study. They were classified in accordance with the craniovertebral angle (CVA) into two groups. The Forward head posture (FHP) group had CVA of less than 48° (n = 21), while the control group had CVA of more than 48° (n = 19). TMJ repositioning accuracy had been measured by vernier caliper for females in both groups.
Results. Statistical analysis revealed that there were no significant (p > 0.05) differences between both groups regarding TMJ repositioning errors in all directions (mouth opening, protrusion and lateral movements) with eyes open or closed.
Conclusion and Discussion. In post-pubertal females, FHP has no negative effect on TMJ proprioception in all directions whether the eyes are open or closed.
