Hamstrings
High incidence, slow healing, persistent recurrence.
High incidence rate, slow healing, persistent symptoms, and a historically high rate of recurrence have made hamstring injuries a challenge for both athletes and the clinical team responsible for their recovery.
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.
System 4 Supports Hamstring Protocols
Regardless of whether you have an existing process for protecting and strengthening hamstrings, the objective test protocols offered with the 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
The first Return-to-Play report for hamstring injury, now available with System 4 Advantage BX™ software:
- Shows clear pass/fail test results
- Grounded in the latest research
- Simplifies communication with athletes, physicians and third-party payers
-
Supports two commonly used hamstring rehab protocols:• Lengthened State – Multiple Angle Comparison
• Mixed H/Q Ratio

Protocol #1:
Multiple Angle Comparison Test
Protocol #2:
NOTE: This Protocol utilizes the standard Knee Attachment.
