Joint mobilisation Flashcards
Why do we mobilise joints
Healthy joints
Dysfunctional joints e.g. Ankle sprain (ATFL)
Pathological joints e.g. Osteoarthritic shoulder (glenohumeral) joint
mobilisation
‘passive movements performed in such a way that at all times they are within the control of the patient so that he can prevent the movement if he so chooses.’ small - large amplitude, low velocity.
manipulation
‘sudden thrust or movement of small amplitude, performed at a speed that renders the patient powerless to prevent it.’ small amplitude, high velocity.
physiological(osteokinematics) movements
those that patient can carry out actively
accessory arthrokinematic movements
those that patient cannot perform himself but which can be performed on him by someone else
Possible because all joints have certain slackness in capsule & surrounding ligaments
PROM
Passive movements –
Physiological movements that are performed by the therapist – at a single joint or at several joints in sequence to maintain joint range & muscle length
Not graded
PPM
Passive Physiological Mobs (Graded)
PAM
Passive Accessory Mobs (Graded)
Arthrokinematics
(direction of glide)
arthrokinematics is determined by
by morphology (shape) of joint surfaces
Kaltenborn’s Convex-Concave rule
Arthrokinematics (direction of glide) is determined by morphology (shape) of joint surfaces
AP accessory movements
anteroposterior glide
PA accessory movements
posteroanterior glide
Longitudinal caudad
caudad
in line with long axis of bone
lat
Lateral distraction
or lateral glide
ceph/comp
Longitudinal cephalad
med
Medial glide
rotator cuffs invest Glenohumeral GH
joint capsule and controls humeral head movements
where does RTC centre
‘centres’ the humeral head to assist in stability of a very mobile joint
RTC has an impact on
on HH gliding directions (think of cellophane)
shoulder rotation
EXTERNAL ROTATION / EXTENSION
INTERNAL ROTATION / FLEXION (ELEVATION)
in vivo
consider impact of tightening capsule and rotator cuff musculature
Accessory Movement Exam can:
Identify & localise symptomatic joint
ASSESS - Define nature of joint motion abnormality
NORMAL vs. HYPOMOBILE vs. HYPERMOBILE
TREAT - Provide basis for selection of treatment techniques.
Exam technique
Apply pressure close to joint line, examine unaffected side first for comparison. note QUALITY RANGE of motion Pain behaviour through range Resistance
grade I
Small-amplitude movement performed at the beginning of range
grade II
Large-amplitude movement performed within a resistance-free part of the range.
Grade III
Large-amplitude movement performed into resistance or up to the limit of the range.
Grade IV
Small-amplitude movement performed well into resistance.
Accessory movements in clinical settings
Position pt comfortably
Examine joint on unaffected side first & compare
Examine initially without feedback – helps learning
Use largest area of skin contact possible for max patient comfort
Keep thumbs straight
how should force be applied
Where possible, clinician’s forearm should lie in direction of applied force
Apply force smoothly & slowly through range to either assess or treat (grades)
