Some patients love and respond well to these techniques and others are quite fearful or have had a bad experience. While Physiotherapists are trained to manipulate or ‘crack’ joints, it is a treatment option that we only employ if it is safe for the individual patient and deemed completely necessary (there are often numerous other treatments that will achieve the same results). Manipulation techniques will not be performed without your prior consent. Moreover, some of our therapists are trained using an IAM/ Activator which is a handheld instrument that can deliver a safe, measured dose of a high velocity thrust force which simulates a “crack” of a joint and is a safer but great treatment option (especially when pregnant) for painful, stiff or locked joints.
