    Conclusion: The obtained results conclude piano players are highly prone to the risk of developing PRMSD in the upper body.

    Results: The findings showed piano players have a higher NDI, lower CVA, and RSP when compared with the non-piano players at a statistically significant level of p-value <0.05.

    Objective: Playing-related musculoskeletal disorders (PRMSD) are a common problem for the pianist. The poor upper body ergonomics influences the natural positioning of the neck and shoulders, which involves forward head posture (FHP) and rounded shoulder posture (RSP). This misaligned position could produce a sensation of pain over the upper body, which affects the piano player and computer users with similar ergonomic posture. Recently, photogrammetry methods are commonly applied in a clinical setting to assess posture. The goal of this research is to compare the upper body playing-related muscu-loskeletal disorders between the piano and the non-piano players by applying photogrammetry.

    Materials and Methods: This causal-comparative study includes 70 participants with 35 piano and 35 non-piano players. The participant's FHP was assessed using a digitized photo to record the Craniovertebral angle (CVA) with the support of Kinovea software. Besides, digital Vernier Calliper used to assess the scapular index on the RSP and Neck disability indices (NDI) used to measure neck pain and functional disability of the participants.

  2. Facial dimensions of Malay children with repaired unilateral cleft lip and palate: a three dimensional analysis
    Zreaqat M, Hassan R, Halim AS
    Int J Oral Maxillofac Surg, 2012 Jun;41(6):783-8.
    PMID: 22424709 DOI: 10.1016/j.ijom.2012.02.003
    This comparative cross-sectional study assessed the facial surface dimensions of a group of Malay children with unilateral cleft lip and palate (UCLP) and compared them with a control group. 30 Malay children with UCLP aged 8-10 years and 30 unaffected age-matched children were voluntarily recruited from the Orthodontic Specialist Clinic in Hospital Universiti Sains Malaysia (HUSM). For the cleft group, lip and palate were repaired and assessment was performed prior to alveolar bone grafting and orthodontic treatment. The investigation was carried out using 3D digital stereophotogrammetry. 23 variables and two ratios were compared three-dimensionally between both groups. Statistically significant dimensional differences (P<0.05) were found between the UCLP Malay group and the control group mainly in the nasolabial region. These include increased alar base and alar base root width, shorter upper lip length, and increased nose base/mouth width ratio in the UCLP group. There were significant differences between the facial surface morphology of UCLP Malay children and control subjects. Particular surgical procedures performed during primary surgeries may contribute to these differences and negatively affect the surgical outcome.

  3. Facial soft tissue features assessed with finite element analysis
    Banabilh SM, Rajion ZA, Samsudin AR, Singh GD
    Int J Orthod Milwaukee, 2006;17(4):17-20.
    PMID: 17256439
    Facial soft tissues are a major determinant of treatment choice. When Class I and Class II malocclusions were compared using finite-element analysis, morphologic differences were localized and quantified. This study highlights the importance of determining the timing, magnitude and direction offacial growth prior to treatment to achieve stable results.
