| Case History |
| Dropped
Pelvis |
| I was asked to take a look at
'Myra', a 14.1 part bred Arab mare. |
| Her owner reported that during
the previous 6 months, Myra had been progressively faltering in her schooling
work; resisting upward transitions into, falling in on the right rein,
snatching at the bit and unable to maintain a steady pace. |
| After various questions and
track checks, the problem revealed itself. |
| Myra's conformation presented a
pelvic structure that appeared uneven and misaligned. Her offside pelvic
arrangement was an inch or so lower than the nearside. |
| As
drastic as this sounds, it is surprisingly not confined to rarity. Any
horse working and living within human domestication can fall victim to this
condition. However, the influencing factors leave some horses more
vulnerable than others.
|
| The Pelvis, Sacrum
and Sacroiliac Joint |
|
The
sacrum is a triangular type shaped bone composed of 5 vertebrae that fuse
together when the horse reaches between 4 - 5 years of age.
Integrated into the
pelvic girdle, the sacrum forms a skeletal link between the hindquarters
and the horses back.
|
| The lower
aspect of the sacrum has a sacral vertebra on either side forming
a Synovial joint, often referred to as the 'sacral wing’.
|
| The underside
of each sacral wing unites with the Ilium bone of the pelvis to form
the sacroiliac joint. |
| The
sacroiliac joint is a Synovial and fibro-cartiloginous joint that
creates the meeting point of the pelvic girdle and the vertebrae column.
|
| The
primary role of the sacroiliac joint is to provide stability for
both the vertebrae column and the pelvic girdle; subsequently there is little
flexibility within its physiology.
|
|
The
Pelvis, Sacroiliac Joint and The Horses Locomotion |
|
Energy and
movement generated from the hindquarters relies upon the sacrum and the
sacroiliac joint to transmit its forces through to the horses body and
forehand.
The
gaits of walk and trot protract the hindlimbs alternatively, this action
and energy is received and transmitted by the sacroiliac joint.
The
gaits of canter and gallop as well as jumping protract the hindlimbs
together, this action and energy is received and transmitted by
the integrated workings of the sacroiliac joint and lumbosacral joint that
work together to rotate the pelvis.
|
| Signs Of Sacroiliac Strain |
| A strained sacroiliac
joint will have its structure weakened, either immediately or
progressively over time, depending upon the severity of the strain. Consequently, the sacrum's'
ability to support the pelvic girdle becomes inhibited.
|
| If
the sacroiliac structure continues to weaken, the 'tuber sacral' (point of
croup) and the 'tuber cocoxae' (point of hip) can sometimes rotate, falling
into misalignment. This is detectable when viewing the pelvis from behind, the
injured structure will present itself with one hip lower than its should be.
|
| In
addition to this, when the horse is lead out in hand, he may also
present
a loose or unsupported locomotion originating from the hindquarters, often dragging the hind toe of the
strained limb.
|
| During
ridden locomotion, the horse will often hold his tail over to the
strained side, while also demonstrating an inability or resistance to engage his hindquarters.
The overall locomotion will be abrupt and stiff with disunited strides and
comparative lameness in relation to the severity of the strain.
|
| All
this pain and discomfort will be radiate through the back;
subsequently extreme sensitivity of the lumbar region can be detected, often
promoting a hollow back action coupled with the neck stretched high above
the bit as the horse tries to relieve and stretch out his pain
and tension. Other horses will try to stretch out the pain
and tension by leaning heavily onto the forehand and into the
bit. either methods of relief will over time encourage a locking of the
lumbar vertebrae. |
| This
can proceed to negatively influences the horses cranialsacral system, seeing
the horse begin a new action of biting at the bit in efforts to relive
poll tension. (diploma course) |
| Whichever method
of relief is demonstrated, the horse may also 'fall in' on
the rein that is stretching the affected side of injury, while continuing
to enhance the pelvic malfunction and promote imbalances within the
cranialsacral system. |

| Equine Massage Therapy and Sacroiliac
Strain |
| With
respect to the interactive workings of equine massage therapy and the physiology of the sacroiliac joint,
equine massage
therapy needs to be applied in a progressive and intellectually
devised form, customised to each horses individual needs and dictations. |
| In this
specific case, the chiropractor and myself worked together to harmonise our treatments in
order to benefit from their individual and collective effects.
|
| After the
initial assessment involving the horses age, lifestyle, tack, working discipline,
conformation and specific influences, the first stage is implemented. (this
is a non comprehensive account) |
| 1st Stage |
| Detection
of muscular tension in the immediate, compensatory and referred
muscles, ligaments and associated fascia planes |

| 2nd Stage |
| Myofascial therapy to release adhesed
fibres, thus releasing their holding pattern on the associated muscles,
ligaments and skeletal structure |
| 3rd Stage |
| Relaxation of muscles and
ligament structures |
| 4th Stage |
| Release of stress points |
| Release of trigger points |
| 5th Stage |
| Work
with the horses own accepted though incorrect form of locomotion through
the laws of the proprioceptive sense, allowing a new recognition of
locomotion to enhance the new muscular tone,
strength and positive development.
|
|
The
horses loins require a balanced form in harmony with the structures that they
support. Over developed loins will create a line of tension within their supporting
structures.
|
| In
this case, the off-side hamstring muscles, hindquarters and loins were in a
poor and weak condition; while the near side hamstring muscles, hindquarters
and loins presented an incomparative state of over-development. This was particularly obvious with the
poverty line seen running between the Semitendinosus and Bicep Femoris.

|
| The
Jumping Horse |
| The
horse is not physiologically designed for jumping!
|
| Naturally,
the only reason a horse is able to jump is for its own
survival in the wild.
|
|
Jumping
is an unnatural action for the horse, and subsequently, the horse has
failed to evolve with the physical influences to
incorporate jumping as an everyday activity.
Small
lower limbs, an inflexible spine, a heavy forehand (designed for
pulling the hindquarters in the wild), long neck with a comparatively
large heavy head as
well as visionary inhibitions
do
not equate to the physical ideals required for jumping.
|
| Couple
this with the weight of the rider and the restrictions of tack, we can
begin to understand just how the show jumper will naturally develop various muscular
stresses.
|
| Muscular
Stress and The Jumping Horse |
| In order to perform a jump, the
horse prepares, enters and completes 5 separate phases of physiological
demands. Lets take look . . |
| 1 - Take
Off |
| Requires flexion
of the lumbar region, hindquarters and stifle to enable the recoiling and lowering
of the hindquarters; providing the means for concentrated energy that
will propel the up and over the forthcoming jump.
|
| The
primary muscles used in take off are: |
| *
Rhomboid - raises shoulder
|
| *
Thoracic and Cervical Trapezius - raises shoulder
|
| *
Brachiocephalicus - raises forelimb
|
| *
Long
digital flexor - flexes the hoof
|
| *
Long
digital extensor - extends the hoof
|
| *
Semimembranosus - flexes the hip
|
| *
Semimembranosus - flexes the hip
|
| *
Iliacus - flexes the hip
|
| *
Tensor Fascia Latae - flexes the hip / extends the stifle
|
| *
Bicep femoris - flexes the stifle and hock
|
| *
Belly of bicep femoris -
flexes
the stifle and hock
|
| *
Superficial gluteus - extends the hip
|
| *
Gluteus - forward propulsion
|
| 2
- Stretching
over the jump requires the horse to lower his head in order to raise his withers, while
at the same time flexing his hocks and extending his forelimbs
journey over the jump.
|
| The
primary muscles used for stretching over a jump are:-
|
| *
Brachiocephalicus
muscle - provides lateral flexion of the neck and assists with the raising
of the shoulder and forelimbs |
| *
Thoracic Trapezius - provides forelimb protraction |
| *
Sternothyrohyoid and Omohyoid muscles - provides lateral flexion of the neck while allowing
the head to rotate in the opposite direction |
| *
Longissimus
dorsi - (see summer newsletter 2005) - extends the back and provides lateral
flexion
|
| *
Iliocostalis
dorsi - provides continued lateral flexion of the trunk derived from lateral
flexion provided by the longissimus dorsi |
| *
Gastrocnemius
muscle - hock extension and stifle flexion allowing the hindlimbs to kick
out so that they may clear the jump
|
| 3
- Landing
from the jump exerts a great deal of immediate stress to the tendons, ligaments and muscles of the forelimbs,
shoulders,
chest, neck and back
|
As
the horse lands, the leading forelimb makes ground contact establishing
the horses balance and support, followed by the immediate impact of the preceding
forelimb
|
| Meanwhile,
the hindlimbs are independently folded up under the horses body before
impacting the ground one by one following the forelimbs |
| As
the last hindlimb establishes ground contact, the leading forelimb will have already
pushed off for the getaway phase. This places a great deal of tension and stress
to the leading forelimb, its respective shoulder as well as the caudal and
cranial aspects of the chest |
| If
the horse lands with the forelimb too far forward, the
toe turns up leaving the heel to make the initial ground contact. |
| This
will proceed to abruptly stretch the deep flexor tendon; a common
experience with horses whom present poorly aligned, weak
or long pasterns |
| The
primary muscles used in landing are: |
| *
Upper
triceps - flexes the shoulder joint
|
| *
Lower
triceps - extends, stablises and supports the elbow joint |
| *
Supraspinitus
muscle - extends the shoulder while providing support and stabilisation |
| *
Infraspinitus - assists the supraspinitus muscle while abducting the shoulder |
| *
Cranial
superficial pectoral muscle - adducts the forelimb
|
| *
Caudal
superficial pectoral muscle - retracts the forelimb to its former stance
|
| *
Spinilus
dorsi muscle - extends the back
|
| *
Longissimus
dorsi - (see summer newsletter 2005) - extends the back and provides lateral
flexion |
| *
Iliocostalis
dorsi - provides continued lateral flexion of the trunk derived from lateral
flexion provided by the longissimus dorsi |
| *
Brachiocephalicus
muscle - provides lateral flexion of the neck and assists with raising
of the shoulder and forelimbs
|
| *
Sternothyrohyoid and Omohyoid muscles - provides lateral flexion of the neck while allowing
the head to rotate in the opposite direction |
| Massage
and The Jumping Horse |
| The
unnatural act of jumping along with its physiological demands denotes that
the jumping horse remains vulnerable to the development of cranialsacral imbalance as well as one
sided development. Looking at the working roles of the primary muscles along with their
tendons and skeletal attachments, you will be able to see how a domino effect, effective in both a positive and negative
pattern is so easily created; one of which will proceed to radiate good
health or line of stress and tension. (Ref: student papers - stress point
cycle / diploma course - myofascial release / cranialsacral therapy) |
| Therefore,
effective and respectively applied equine massage therapy needs to be
applied
to the entirety of the jumping horse, with additional emphasis upon the
primary muscles, cranialsacral system and the sources and progressive
influences active within any one sided development. |
| Subsequently,
the equine massage therapist needs to advise the
owner / trainer on the sources, progression and maintenance of each horses
muscular health so that appropriate actions may be implemented by the
owner / trainer in the horses day to day to day care, tack, handling and riding
so that the respective massage and myofascial therapy previously applied
is still of continuing physical and emotional benefit to the jumping
horse. |

|
| The
Pelham Bit |
| The
rider of the horse working in a pelham bit needs to understand how the bit is
working and why it is being used.
|
| Sadly,
many horses are ridden in the pelham so that they are able to present a false representation
of the desired neck
outline described as being 'on the bit'. |
|
For
any horse to work 'on the bit' requires an unhurried learning process
for the horse with unhurried, sympathetic and intellectual teachings from
an experienced rider.
|
| The
trained eye can easily differentiate between the horse who is working in
communication with his rider and the horse who is being leveraged into
a detrimental neck outline derived through the effects of an
incorrectly used pelham bit. (Ref: student papers - stress points and the
dressage horse) |
| How
The Pelham Bit Works (Ref:
foundation course - module III) |
| There
are many variations of the pelham bit family, including the
'scamperdale', 'kimblewick' and 'half-moon mullen', all of which respectively integrate the workings of both the snaffle bit and
the curb bit. |
| Most
basically speaking, the pelham bit works by creating a severe leverage action upon the bars
of the horses mouth and tongue that then radiates pressure upon the poll,
through the neck where it then radiates through the cranialsacral system.
|
| The upper section
of the pelham creates the kinder snaffle action, while the lower section of
the pelham creates the more severe action of the curb bit. |
| While both sections have their own reins, the pelham bit
should only be ridden from the snaffle rein, only utilising the curb rein
with the riders intellectual awareness and targeted reasons for doing
so. |
| Subsequently, each horse will present personal levels
and forms of stress derived from the pelham bit dependant upon its own physiological state
of health. e.g. natural flexion, muscular health, myofascial health, cranialsacral
balance together with the
understanding of the riders aids
|
| The
Pelham Bit and Muscular Complications |
| Many
people have been bewildered saying, "How can a bit create muscular implications"?
Well, I will often get right to the root of the problem and proceed to
add
more bewilderment before I answer by suggesting that the horses cranialsacral
system and myofascial network also remain under severe threat of
malfunction.
|
| The
problem lies in the complete contradictions of the horses physiology and
the working effects of the pelham bit when used incorrectly. |
The
horse that has been trained to communicate and work in unison with his
rider, and over time will have learnt to move in new ways away from his natural
instinctual actions and adapt accordingly, allowing the horse to work with
impulsion, rhythm and balance generated from his powerful hindquarters to
be received by a light, flexible and receptive forehand.
|
The
horse
will have learnt to utilise his power to serve as a form of propulsion
to push his movement forward, and, only
when the horse has learnt these techniques will he naturally raise his neck,
flex at the poll (Ref: diploma course - cranialsacral therapy) at the first cervical
vertebrae, while still maintaining and
working with flexion and free movement.
|
This blend of
harmonious communication between rider and horse presents the most desired outline
the horse and rider can achieve,
and
horses whom have not experienced the above teachings and understanding will
often attempt to achieve the false neck outline courtesy of the pelham bit,
minus flexion, elasticity of movement and mutual communication with
the rider.
|
| Subsequently,
the horse will achieve the raised arched neck and tucked in head by being
leveraged from the 5th or 6th neck vertebrae
|
| The
implications of this serve to directly affect the following muscles and
soft tissue structures: |
| Primary
Muscles: |
| * Rhomboid
muscle - absorbs tension from the nuchae ligament subsequently inhibiting
foreleg protraction |
| *
Brachiocephalicus - lateral neck and head movement / assists with raising
the neck |
| *
Splenius - Lateral flexion of the head |
| * Rectus
capitus muscles - flexes the head at the poll |
| *
Sternothyrohyoid and Omohyoid muscles - lateral head movement |
| *
Longissimus Dorsi - extends back muscles and transmits energy as well as
tension |
| * Spinalis
Dorsi - back extension and absorbing tension
in the neck cervical vertebrae proceeding to inhibit spinal flexion |
| Ligaments: |
| Nuchae ligament - supports and absorbs tension created within the neck
muscles and thus dictating its abilities of flexion |
| Supraspinous
ligament - supports and absorbs tension
derived from the nuchae ligament as well as absorbing tension within the
back and thus dictating its abilities of flexion |
| Sacroiliac
ligament - supports and absorbs tension
derived from the nuchae and Supraspinous ligament
as well as absorbing tension within the lumbar region and thus dictating
its abilities of strength, action and flexion |
| Structures: |
| Hyoid Apparatus - connects the
tongue to jaw muscles to caudal aspect of the skull to the brachiocephalic
to the sternocephalic - to the poll to the nuchal ligament to the cervical
and thoracic serrate muscle down to the muscles of the sternum and shoulder. |
| Thus the horses general
forehand locomotion may seemingly fall out of rhythm leaving compensatory
muscles to realign his centre of balance, and there begins a whole new
series of muscular stress. |
| Psychological
Implications (Ref: student
paper - the tense horse) |
| Horses
are not born with bad mouths; they are developed by careless riders,
rough green riding and handling, coupled with thoughtless biting. Horses unfortunate
enough to be ridden incorrectly with the pelham bit will often be in
some form of discomfort.
subsequently, this naturally promotes the horse to behave in a tense manner of
unease and resistance, prompting a vicious cycle of muscular stress - trigger
points - pain/discomfort
- anxiety - muscular stress - trigger points - more pain/discomfort - more anxiety and so on. |
| Equine
Massage and The Pelham Bit |
|
Horses
being assessed for equine massage therapy, must always have their tack taken into
account. Most horses ridden in a pelham bit will have muscular
stress present in both the directly and indirectly affected muscles.
Subsequently,
the indirectly affected muscles, ligaments and fascia planes will radiate
their tension through the entirety of the horse, ultimately leading the
horse to present complications in his locomotion and behaviour that would seemingly
have no relationship to the 'bit'.
An
intellectually devised programme of craniosacral, myofascial and specific muscular
release will work to psychologically relax the horse, allowing ideal conditions
for the proceeded targeted therapy.
|
| Back to the
top |
|
| The
Brachiocephalicus (Ref:
student papers - stress point cycle) |
| The
Brachiocephalic muscle is a real multi-tasker, initiating a host of varied
muscular workings, and thus remains vulnerable to many sources and forms of muscular
stress. Subsequently, when thus muscle experiences stress it will proceed
to inhibit a many forms of the horses locomotion and working ability. |
Location
- Situated
within the superficial muscle layer running down either side of the neck
|
| Origin
- First
cervical vertebrae at the base of the skull (correct flexion point for horses
'on the bit - see pelham bit) |
Insertion
- Point of
shoulder (top of the
humerus)
|
| Workings |
| The
Brachiocephalic muscle works
with the Splenius muscle to both balance the horse before the horses neck is
turned into the contracted side (lateral flexion) |
| The Brachiocephalic muscle will
simultaneously contracting to raise
the scapula before working
with the Supraspinitus and Infraspinitus muscles to initiate forelimb
protraction, retraction, abduction, adduction and stability |
| Associated
Implications |
| A
loss of lateral flexion in the neck |
| A
loss of rhythm, power and co-ordination of the forelimbs |
| Disunited
paces |
| Inability
to balance effectively |
| Shortened,
abrupt strides - increasing concussive forces |
| Leaning
on the forehand in attempts to stretch out the tension - this creating
consequential muscular stress in the compensating muscles |
| Inability
to jump, stretch and land effectively.
|
| Anyone
of these associated implications will bring with them their own origins of
muscular stress with their patterns of radiated tension and compensatory
consequences. |
| Massage
and The Brachiocephalicus |
| Being
host to one of the 7 major recognised stress points, the Brachiocephalic
muscle is usually guaranteed to be housing some form of stressed within the
working or even retired horse. |
|
A stressed
or strained Brachiocephalicus will create immediate, progressive and / or
consequential effects, individually and collectively affecting the horses
physiological and psychological well being.
|
|
An
assessment of the horses working discipline, life style, tack, gait analysis and
character provides a good insight into the possible causes, creations and continuing
patterns of stress either present or threatening to this major muscle.
|
| Being
one of the bigger muscles, its compensatory affects are vast and rapid,
often dictating the need for additional treatment to the associated
tendons, ligaments, fascia planes and often cranialsacral imbalance.

Inside
The Muscle Cell (Certificate
Course)
|
|
Looking
inside a muscle is rather like looking into a miniature world complete with
its own army, inside their own barracks with the soldiers harmoniously
communicating and working within its effective laws of 'cause and
effect'.
|
| Although
seemingly complex at first sight, it soon becomes clear just how logical
though powerfully effective (positively and negatively) a muscle is.
|
| Massage
and The Muscle Cells |
|
Recognising
the cellular level of the muscle is equally important as recognising the
more superficial level.
|
|
When
you apply massage applications and techniques to a muscle you are dealing
directly with the bulk of the muscle; the tissue mass with its various fluids,
its tissue density.
|
Muscle
cells are composed from 'cytoplasm', a gel type substance both in its composition
and reactive behaviour.
When
the muscle cell is exposed to times of inactivity, it becomes taught and dense in its
composition; and when exposed to times of activity, it becomes fluid and pliable
in its composition - a process is referred to as 'Thixotrophy'.
Being
able to recognise and understand the behavioural traits of the muscle cell enables you
to intellectually apply equine massage therapy in order to positively influence negative
activity such as muscular tension and myofascial restriction and in each muscle.
Subsequently,
deep massage techniques involving compression, stretching and twisting will
help to initiate and promote the 'Thixotrophy' phenomenon, promoting the muscles
more receptive state for positive results offered through equine massage
therapy.
|
|
With
water being the main component of gel, the cells are very effective at
conducting electricity. Subsequently, nerve impulses are more effectively
received and transmitted when communicated through a soft pliable muscle. This
principle allows many cases of referred neural pain often present within the
internal organ cavities (Ref: diploma course) to be eradicated at their root cause.
|
| By
understanding
the muscle from its basic cellular level allows you to recognise root
causes of many problems and disguised presentations, allowing future and
targeted treatment to be effective minus the negative
influences created by at cellular level.
