Protect, Then Load
Early gentle isometric and range work in the first days to maintain strength without stressing the healing tissue, progressing quickly as the muscle tolerates it.
A hamstring strain is one of the most common sports injuries and one of the most likely to come back if it is rushed or rested too long. At AR Physical Therapy we rehab pulled hamstrings with early, graded loading and objective return-to-sprint testing, with deep tissue laser therapy to manage pain in the early days so the real work can start sooner.
The hamstring heals through progressive load, and the risk of re-injury is decided by how well strength and sprint capacity are restored before you go back. We measure both rather than guess.
See us within the first few days. Early guided loading shortens recovery, and an early evaluation rules out the small number of injuries that need a surgeon.
The hamstrings are the three muscles down the back of the thigh, and they strain in two main ways. Sprint-type strains happen at high speed when the muscle is lengthening under heavy load. Stretch-type strains happen in dancers, martial artists and kickers when the leg is taken into an extreme range. Strains are graded 1 to 3, from a minor pull to a complete tear.
Re-injury rates are high, mainly because athletes return before strength and sprint tolerance have been rebuilt, or because the original cause was never addressed.
A sudden pull at the back of the thigh, pain walking or bending forward, and bruising a few days later all point to a strain worth evaluating.
Every phase is driven by what the muscle can tolerate, and the decision to return is based on numbers rather than how you feel on a good day.

Nordic hamstring curls and related exercises, which have the strongest evidence for both recovery and preventing the next strain.
A graded running progression from jogging through strides to full-speed sprinting, with hip and core strengthening throughout.
Kinvent force plates measure hamstring strength and left-right symmetry, and DorsaVi sensors assess running mechanics before you are cleared.
In the first days after a strain, pain and swelling limit how much you can load the muscle, and loading is what drives recovery. The LightForce Class IV laser is applied over the injured section of the hamstring to increase local circulation and reduce pain, starting at a gentle dose while the tissue is irritable and increasing as it settles.
Laser is FDA-cleared for the temporary relief of muscle pain and spasm and for increasing local blood circulation, which is exactly what an acute muscle strain needs while the fibers repair. It does not speed the muscle's own healing timeline, and it never replaces the loading and sprint progression that get you back on the field.
Our return-to-sport testing is the differentiator here; laser helps you reach the point where that work can begin.
Grade 1 strains typically return to sport in two to three weeks, grade 2 in four to eight, and grade 3 injuries take longer. The single biggest predictor of a good outcome is passing the return-to-sport test before playing.
Normal walking from day one keeps the muscle working without stressing the tear.
Early aggressive stretching can slow healing. Loading, not stretching, rebuilds the muscle.
Do not test it with a sprint until we have tested it on the force plates.
You want to know when you can sprint again and whether it will hold. We answer with force plate numbers, not a calendar.
Not in the first week. Early aggressive stretching can slow healing. Loading, not stretching, is what rebuilds the muscle.
When strength, symmetry and running mechanics meet the return-to-sport criteria we measure on force plates and motion sensors.
Usually because the athlete returned before strength was restored, or because the underlying weakness was never trained. Both are things we fix.
No. You feel gentle warmth, and the dose is kept low while the tissue is irritable.
Book an evaluation in the first few days. Early loading shortens recovery.
