There is mounting evidence that the risk of re-injury can be minimized by using rehabilitation strategies that incorporate neuromuscular control exercises and eccentric strength training, combined with objective measures to assess recovery and readiness to return to sport.1
Regardless of whether you have an existing process for protecting and strengthening hamstrings, the objective test protocols offered with the Biodex™ System 4 will provide valuable, isolated muscle-performance data. Test results, combined with established targeted outcomes, can be used for pre-emptive injury screening, managing rehabilitation and determining readiness for returning to play.
NEW Return-to-Play Reports
Biodex introduces the first Return-to-Play report for hamstring injury, now available with System 4 Advantage BX™ software:
Upgrade path available for existing System 4 and System 3 (rev. 2) dynamometers.
Lengthened State – Multiple Angle Comparison Test
Examines isometric bilateral flexion peak torque symmetry where the limb position puts the hamstring in a lengthened (stretched) state. Passive stretch is the inherent force (or torque) produced by the hamstring in the lengthened state. When deficits are within 10%, predisposition to reinjury is significantly reduced.
NOTE: This Protocol requires 830-550 Hamstring Attachment. Use of any attachment other than the 830-550, is outside proper and intended use.
ECCENTRIC STRENGTHENING AT LONG MUSCLE LENGTHS REDUCES HAMSTRING STRAIN RECURRENCES.
Tyler, et al; Orthopedic J Sports Med. Aug, 2014.
Mixed H/Q Ratio Test
Uses a ratio of eccentric and concentric flexion peak torque where, if the ratio exceeds 1.4, hamstring injury is greatly diminished.
Now available with Advantage BX™ 5.3.
NOTE: This Protocol utilizes the standard Biodex Knee Attachment.
