Influence Of Sleeping In Hammocks On The Orthostatic Posture
Keywords:Sleep system, Photogrammetry alignment postural Evaluation.
Background: Our research team believes that the arrangement of the hammock may influence the orthostatic posture. The aim of the present study was to assess the orthostatic posture in right and left views among hammock-users and hammock non-users of northeastern Brazil.
Methods: Were included 32 healthy participants, subdivided into two groups: hammock non-users, and hammock-users, both in the last 10 years. The orthostatic posture was performed through photogrammetry analysis (PAS/SAPO). We analyzed body alignment variables: horizontal alignment of the head, vertical alignment of the head, vertical alignment of the trunk, hip angle, body vertical alignments, horizontal alignment of the pelvis, knee angle, and ankle angle.
Results: On the right side, there was statistically significant difference in the horizontal alignment of the head (P = 0.04), hip angle (P = 0.02), vertical alignment of the body (P = 0.01) and horizontal alignment of the pelvis (P = 0.03). In the left side, there was statistically significant difference in horizontal alignment of the head (P = 0.04) and the horizontal alignment of the pelvis (P = 0.04).
Conclusion: Sleeping in the hammock influenced the orthostatic posture, especially in horizontal alignment of the head, hip angle, the vertical alignment of the body and horizontal alignment of the pelvis in the side views. Our data open new possibilities of research in this area, which has been obscure until this moment, and enable the indication or contraindication to sleep in hammocks.
