Brief Summary

Determine the posturographic characteristics of eccentric, isometric and concentric movements in healthy subjects as well as in subjects with chronic, orthopedic conditions / pain not involving the lower extremities. The squatting movement (going down from a stand up position, bending the ankle, knee and hip joints, and then returning to the stand up position, while not lifting the feet from the supporting ground surface) is a simple motion that involves all three types of movements: eccentric (the going down), isometric (holding the down position for a couple of seconds) and concentric (the coming up). It is hypothesized that non-healthy subjects will not have "smooth" movements, and posturography could be used to separate between healthy and non-healthy subjects.

Conditions

Chronic Pain; Musculoskeletal Pain

Keywords

balance, postural; postural equilibrium

Outcome Measures

Primary Outcomes (1)

• Stability Score

  The Stability Score (calculated as percentage ratio of the actual sway and the theoretical limit of stability) will be used to investigate if there is any difference between healthy controls and subjects affected by chronic pain not involving the lower extremities. Statistical tools such t-tests and correlation coefficients will be used for assess if there is a difference between the two groups

Secondary Outcomes (3)

• average velocity moment [mm^2/s]

  immediately after data collection

• sway path length [mm]

• frequency content [Hz]

participant undergoing posturographic evaluation

Other: Posturographic evaluation

Interventions

Posturographic evaluation OTHER

Subjects will undergo CDP testing using the modified Clinical Testing of Sensory Integration in Balance (mCTSIB) protocol. Subsequently, subjects will be asked to stand first on the right leg and then on the left leg with eyes open. Finally, subjects will be asked to perform 10 repetition of the squatting movement, with the operator pacing them (telling them when to start and when to stop the movements).
