Efficacy of head postural correction program on craniovertebral angle, scapular position, and dominant hand grip strength in forward head posture subjects: A randomized controlled trial.

OBJECTIVE: Forward head posture (FHP) is a common postural disorder that alters shoulder function. This study examined the efficacy of a corrective program involving postural correction exercises (PCEs), scapular stabilization exercises (SSEs), and kinesiotaping (KT) on improving craniovertebral angle (CVA), scapular position, and dominant hand grip strength (HGS) in individuals with FHP. METHODS: Sixty subjects (8 males and 52 females, 18-40 years old) were randomly allocated into four equal groups: Group A: received PCEs only, Group B: received PCEs and SSEs, Group C: received PCEs and KT, Group D: received PCEs, SSEs and KT. All subjects received treatment for 4 weeks (4 times/week) and postural advice. Outcome measures included cranio-vertebral angle (CVA), scapular position using Lateral Scapular Slide Test and dominant HGS using a CAMRY dynamometer 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, scapular position and dominant HGS) in favor of group (D). CONCLUSION: Combination of PCEs, SSEs and KT interventions has achieved the best gains in terms of CVA, dominant HGS and regaining optimal scapular position in FHP subjects.

The correlation between radiographic and surface topography assessments in three plane pelvic parameters.

BACKGROUND: Noninvasive rasterstereography has been reported as a helpful tool for assessing pelvic parameters. However, the validation and reproducibility of this tool are still questionable. OBJECTIVE: To investigate the correlation between video rasterstereography device (VRD) and X-ray photography in terms of validity and reproducibility (inter- and intra-examiner reliability) in pelvic parameters. METHODS: Thirty male and female healthy subjects with a mean age (26.9 ± 4.9 years) participated in this study. Subjects were examined by VRD for three pelvic parameters (pelvic torsion, pelvic tilt, and pelvic inclination). Measurements were conducted by three different examiners. Subjects were examined by X-ray radiography for the same pelvic parameters as well. Pearson correlation coefficient (r) was used to examine the validity and Intra-class correlation coefficient (ICC) was used to check intra- and inter-examiner reliability. RESULTS: For pelvic torsion, tilt, and inclination the validity levels of VRD were 0.867, 0.996, and 0.930 (P < 0.05), respectively; while the intra- and inter-examiner reliability coefficients were 0.999, 0.999, and 0.998 and 0.990, 0.997, and 0.989, respectively. CONCLUSION: The results of this study revealed that the VRD has both high validity and reliability in assessing the selected three pelvic parameters that reflect the three fundamental planes of movement in healthy subjects. Further studies using VRD are recommended to assess low back pain-associated pelvic parameters.
