Benefits of Spinal Manipulation
Spinal palpation refers to manual evaluation of the spine. It requires hands on assessment of the soft tissue and bony elements of the spine. It encompasses the assessment of spinal segment mobility. Palpation is used to evaluate spinal muscles.
Spinal Manipulation
Spinal manipulation refers to manual movement of a joint into the paraphysiological range. Manipulation requires a short amplitude high velocity movement. Manipulation of a spinal joint is often accompanied by a cavitation or gapping of the involved joints. This results in a transient vacuum phenomenon in the joint thought to involve gas separating from the fluid. This mechanism is typically associated with an audible pop or click. Spinal manipulation is used to improve or restore joint mobility.
Spine Mobilization
The term spine mobilization refers to passive movement of a spinal segment for the purpose of improving its range of joint motion.
Joint Play: (Accessory Joint Movements)
The term joint play refers to small and precise joint movements, which are not under voluntary control. These small accessory joint movements are necessary to permit normal voluntary joint movement. Complete joint range of motion requires intact voluntary movement and joint play. The bounce at each level of the spine felt by your physician during physical examination represents joint play.
Mechanical Benefits of Spinal Manipulation
Palpatory examination can be performed to determine what spinal segments may benefit from manipulation. These are referred to as manipulatable lesions. Healthcare disciplines use different terminology to essentially describe the same thing. For example the chiropractor (DC) may refer to segmental dysfunction or spinal subluxation. An osteopath (DO) may use the term somatic dysfunction. Spinal segmental dysfunction is characterized by abnormal segment movement in the form of fixation (fusion), hypomobility or hypermobility. Abnormal segment movement may or may not be associated with symptoms.
Mechanisms proposed to cause or contribute to spinal segment dysfunction include:
- Entrapment of a spinal joint inclusion or meniscoid
- Entrapment of a disc
- Spinal segment stiffness secondary to adhesions/scar tissue
- Spine segment stiffness secondary to degenerative changes
- Spine segment stiffness due to adaptive shortening of muscle/myofascial tissues
- Deep spinal muscle hypertonicity and/or spasm
