II. INTERVENTION
activity participation
Motor learning strategies
In the early stage, practice can be expected to
improve learning and performance.
Large number of repetitions to develop
procedural skills
Long and complex movement sequence should
be broken down into component parts
In favor of a blocked practice order, thereby
reducing the effects of contextual interference
Task should be modified and minimized
With advanced cases, compensatory strategies
are utilized
Relaxation Exercises
Gentle rocking to produce generalized
relaxation of excessive muscle tension d/t
rigidity
PNF technique of Rhythmic Initiation helps
overcome the effects of rigidity
Diaphragmatic breathing during exercises
Stress management techniques are an
important adjunct to relaxation training
Jacobson progressive relaxation techniques
Flexibility
AROM and PROM exercises are used to
improve flexibility. AROM exercises emphasize
active motions and PROM exercises work
within the pt‘s available ROM to maintain range.
Stretching techniques to elongate muscles. Can
also be combined with joint mobilization
techniques to reduce tightness of the joint
capsule or of ligaments around a joint. Stretch
should maintain at least 20-30 secs/3-5x/20-
30mins
Passive positioning can also be used to stretch
tight muscles and soft tissues.
Address contractures.
Mobility
As well as controlled mobility
Include the muscles of the face
Balance
“Kitchen sink exercises” consists of heel-rises
and toe-offs, partial wall squats and chair rises,
single limb stance with side-kicks or back-kicks,
and marching in place.
Gait training
Designed to lengthen stride, broaden BOS,
improve stepping, improve heel-toe gait pattern,
increase contralateral trunk movement and arm
swing, inc speed & provide a program of regular
walking.
For improving upright alignment: have the pt
walk with vertical poles (pole walking) and
verbal cues to ‗walk tall‘
PNF patterns can be used
Provide visual cues as well as auditory cues
