The Physiotherapy treatment of musculoskeletal injuries has progressed from its foundation in remedial gymnastics and active exercise to therapist-applied passive physiological movements and on to therapist-applied accessory techniques. Brian Mulligan's concept of mobilisations with movement (MWMS) in the extremities and sustained natural apophyseal glides (SNAGS) in the spine are the logical continuance of this evolution with the concurrent application of both therapist applied accessory and patient generated active physiological movements.
Health Practitioners trained in manual therapy assist individuals with impairments of mobility and function. The Mulligan Concept of manual therapy is specifically designed to achieve these goals through the application of pain-free manual mobilization techniques that allow pain-free movement and therapeutic loading of the musculoskeletal system. Both the clinician and the patient can quickly assess the value of this approach by its ability to immediately abolish painful limitations of function. If the techniques are indicated, an immediate improvement in pain, mobility and function will be observed during and following the technique application. If no immediate improvement is noted, the technique must be modified to achieve pain-free function or is not indicated at that time.
• Pain is of mechanical not inflammatory origin
• Acute pain-limited mobility
• Sub-acute mobility impairments
• Post-surgical status with residual loss of mobility
• Cervicogenic headaches and/or dizziness
• Inversion sprain of ankle
• Lateral epicondylalgia
In the application of manual therapy techniques, Physiotherapists acknowledge that contraindications to treatment exist and should be respected at all times. Although always guided by the basic rule of never causing pain, therapist choosing to make use of SNAGS in the spine and MWMs in the extremities must still know and abide by the basic rules of application of manual therapy techniques.
Specific to the application of MWM and SNAGS in clinical practice, the following basic principles have been developed
1. During assessment the therapist will identify one or more comparable signs as described by Maitland. These signs may be a loss of joint movement, pain associated with movement, or pain associated with specific functional activities (i.e., lateral elbow pain with resisted wrist extension, adverse neural tension).
2. A passive accessory joint mobilization is applied following the principles of Kaltenborn (i.e., parallel or perpendicular to the joint plane). This accessory glide must itself be pain free.
3. The therapist must continuously monitor the patient's reaction to ensure no pain is recreated. Utilizing his/her knowledge of joint arthrology, a well-developed sense of tissue tension and clinical reasoning, the therapist investigates various combinations of parallel or perpendicular glides to find the correct treatment plane and grade of movement.
4. While sustaining the accessory glide, the patient is requested to perform the comparable sign. The comparable sign should now be significantly improved (i.e., increased range of motion, and a significantly decreased or better yet, absence of the original pain).
5. Failure to improve the comparable sign would indicate that the therapist has not found the correct contact point, treatment plane, grade or direction of mobilization, spinal segment or that the technique is not indicated.
6. The previously restricted and/or painful motion or activity is repeated by the patient while the therapist continues to maintain the appropriate accessory glide. Further gains are expected with repetition during a treatment session typically involving three sets of ten repetitions.
7. Further gains may be realized through the application of passive overpressure at the end of available range. It is expected that this overpressure is again, pain-free.
