Resumen: Objective
To analyze the changes over time in the strain on the inferior iliofemoral (IIF) ligament when a constant high-force long-axis distraction mobilization (LADM) was applied over 5 minutes.
Design
A cross-sectional laboratory cadaveric study.
Setting
Anatomy laboratory.
Participants
Thirteen hip joints from 9 fresh-frozen cadavers (mean age, 75.6±7.8 years; N=13).
Interventions
High-force LADM in open-packed position was sustained for a period of 5 minutes.
Main Outcome Measure(s)
Strain on IFF ligament was measured over time with a microminiature differential variable reluctance transducer. Strain measurements were taken at every 15 seconds for the first 3 minutes and every 30 seconds for the next 2 minutes.
Results
Major changes in strain occurred in the first minute of high-force LADM application. The greatest increase in strain on the IFF ligament occurred at the first 15 seconds (7.3±7.2%). At 30 seconds, the increase in strain was 10.1±9.6%, the half of the total increase at the end of the 5-minute high-force LADM (20.2±8.5%). Significant changes in strain measures were shown to occur at 45 seconds of high-force LADM (F=18.11; P<.001).
Conclusions
When a 5-minute high-force LADM was applied, the major changes in the strain on IIF ligament occurred in the first minute of the mobilization. A high-force LADM mobilization should be sustained at least 45 seconds to produce a significant change in the strain of capsular–ligament tissue.
