These are specific exercises to restore precise movement to protect and stabilise the joints during movement and static postures. Pain may occur during certain movement directions or specific movements, for example shoulder pain when throwing a ball or low back pain when bending down. Pain may also occur during sustained body postures, for example back pain when sitting at a computer for long periods, or standing in the kitchen. Muscle imbalances, length differences may cause stress on joints that result in pain or pain may cause maladaptive movements that bring about muscle imbalances. If these imbalances are not corrected they may result in continuing musculoskeletal pain. Exercises that address muscle imbalances are important in reducing pain and preventing injury. Musculoskeletal physiotherapist are trained to seek out the source of your pain and then target specific source or mechanism of your pain.
