The hamstring muscle group consists of the semimembranosus, semitendinosus and bicep femoris muscles. All three muscles originate from the ischial tuberosity apart from the short head of bicep femoris which originates from the linea aspera and lateral supercondylar ridge of the femur. The semimembranosus inserts onto the medial condyle of the tibia. The semitendinosus inserts onto the superior medial surface of the tibia and the oblique popliteal ligament and both heads of the bicep femoris muscle insert onto the head of fibular. All 3 muscles are innervated by the tibial nerve with the short head of the bicep femoris being innervated by the common peroneal nerve. The hamstrings have a fascial connection to the peroneus brevis muscle linking to actions at the foot and the ankle, and the sacrotuberous ligament linking it with the pelvis and thoracolumbar fascia (Hoskins and Pollard, 2005).

Why does my shoulder hurt? A common question we are asked several times daily at Physioimpulse.  This dissection illustrates one possible cause beautifully.  The rotator cuff is made up of 4 muscles which essentially help to centre the ball (humeral head) in the socket (glenoid) at the shoulder joint.  Tears, under activity or overactivity in any or all of these muscles can lead to "impingement" pain in the shoulder.  People commonly suffer pinching pain with repetitive manual work, reaching and elevating the arms above 90 degrees.  You don't need to suffer with these pains and a long course of pain relief is not always the answer.  Following a full physiotherapy assessment our team can provide hands on therapy, taping, acupuncture and tailored rehab to restore full movement and pain free living!
