이중 나선형으로 우리 몸을 감싸 돌아 연결하는 해부학 연결선 "나선선"
근육들은 각각 서로다른 작용을 하는 순간에도 거미줄처럼 연결된 근막을 통해 전신에 걸쳐 기능적으로 통합된 영속적인 영향을 미친다. 인체의 결합조직 섬유의 날줄과 씨줄(the warp and weft)을 따라 형성되는 근막의 얇은 판과 선(sheets and lines)들은 그 경로를 확인할 수 있는 근육근막경선을 형성한다. 안정성, 뒤틀림, 긴장, 고착, 탄성 그리고 보상적 자세들은 모드 이러한 경선들을 따라 나타난다.
Overview 나선선의 개요
The Spiral Line (SPL) (Fig. 6.1) loops around the body in a double helix, joining each side of the skull across the upper back to the opposite shoulder, and then around the ribs to cross in the front at the level of the navel to the same hip. From the hip, the Spiral Line passes like a 'jump rope' along the anterolateral thigh and shin to the medial longitudinal arch, passing under the foot and running up the back and outside of the leg to the ischium and into the erector myofascia to end very close to where it started on the skull.
나선선은 이중나선형으로 온몸을 감싸돌아 두개골, 반대측 어깨, 늑골, 배꼽에서 반대쪽 골반으로 교차. 전방허벅지, 정강이 발의 내측종아치로 내려가 다리에서 교차하여 다리 외측, 좌골, 척추기립근, 두개골로 연결됨.
Postural function 나선선의 자세기능
The SPL functions posturally to wrap the body in a double spiral that helps to maintain balance across all
planes (Fig. 6.2A-C/Table 6.1). The SPL connects the foot arches with the pelvic angle, and helps to determine
efficient knee-tracking in walking. In imbalance, the SPL participates in creating, compensating for, and maintaining twists, rotations, and lateral shifts in the body.
나선선은 자세적으로 우리몸의 모든 면(all planes)을 가로질러 균형유지를 돕는 이중나선으로 우리몸을 감싸고 있음.
나선선은 발아치(족궁)와 골반각(pelvic angle)을 연결하여 보행시 효율적인 무릎슬개골주행을 결정하는 것을 도움.
불균형상태에서 나선선은 몸의 비틀림, 회전, 외측변위(lateral shift)를 유지하고 보상움직임을 만드는데 관여함.
Depending on the posture and movement pattern, especially relative to the weighted and unweighted leg,
forces from the legs can travel up the same side or cross to the opposite side of the body at the sacrum. Much of
the myofascia in the SPL also participates in the other cardinal meridians (SBL, SFL, LL) as well as the Deep
Back Arm Line (see Ch. 7). This insures the involvement of the SPL in a multiplicity of functions, and that dysfunction in the Spiral Line will affect the easy functioning of these other lines.
자세와 움직임의 양상에 따라, 특히 체중부하가 주어지는 다리, 주어지지 않는 다리와 연관하여 다리로부터 오는 힘을 천골에서 몸의 동츠으로 이동 또는 반대측으로 이동해감.
나선선에서 대부분의 근육근막은 심부후방상지선뿐 아니라 다른 경선들에서 관여함. 이는 나선선의 기능 다양성에서 나선선의 관여를 확신하는 것이고, 나선선의 기능장애는 다른 선들의 원활한 기능에 영향을 줌.
Movement function 나선선의 움직임 기능
The overall movement function of the SPL is to create and mediate spirals and rotations in the body, and, in eccentric and isometric contraction, to steady the trunk and leg to keep it from folding into rotational collapse.
나선선의 모든 움직임 기능은 몸에 나선과 회전운동을 만들거나 조절하고, 원심성수축과 등척성 수축에서 몸통을 안정적으로 유지시키고, 다리가 회전붕괴로 접히는 것을 막아줌.
For convenience, we will change tactics to begin detailing the SPL from the top, keeping in mind that in vivo
any of these lines can, and do, pull from either end (or outward or inward) from nearly any place along their
length.
Common postural compensation patterns associated with the SPL include: ankle pronation/supination, knee
rotation, pelvic rotation on feet, rib rotation on pelvis, one shoulder lifted or anteriorly shifted, and head tilt,
shift, or rotation.

The rhombo-serratus muscle (the rhomboid-serratus anterior sling) often shows medial to lateral or side-to side imbalance that can be corrected manually. Taking the medial to lateral differences first: a common pattern is that the rhomboids are locked long (overstretched, eccentrically loaded) with the serrati locked short (concentrically loaded), pulling the scapula away from the spine. This pattern will show up commonly in bodybuilders, and those with a tendency to the kyphotic spine (anterior thoracic bend). In these cases, the therapist wants to lengthen the serrati while the client engages the rhomboids.
Fig. 6.5 Taken together, the rhomboids and serratus anterior, the next continuity in the Spiral Line, form a myofascial sling for the scapula. Thus the scapula is suspended between them, and its position will depend on the relative myofascial tone of these two. (Adapted from Calais-Germain 1993.)

The internal oblique pulls the ASIS in a superior and medial direction (Fig. 2.12A). Other internal oblique
fibers, as well as fibers from the transversus abdomens, pull directly medially. Still other fibers of the internal
oblique fan, plus the restraining cord of the inguinal ligament, pull medial and inferior. The sartorius, attaching
to the ASIS on its way to the inner knee, pulls mostly down and slightly in. The iliacus, clinging to the inside
edge of the ASIS, pulls straight down toward the inner part of the femur.
The rectus femoris, as we noted in discussing the Superficial Front Line, does not attach to the ASIS in most people; nevertheless it exerts a downward pull on the front of the hip from its attachment a bit lower on the AIIS. The tensor fasciae latae pulls down and out on its way to the outer aspect of the knee. The gluteus medius pulls down and back toward the greater trochanter, the transversus abdominis pulls back nearly horizontally along the iliac crest, and the external oblique pulls up and back toward the lower edge of the rib cage.
Getting all these forces to balance around the front of the hip in both standing and gait involves an attentive
eye, progressive work, and more than a little patience. This balance involves at least three of the Anatomy
Trains lines - this Spiral Line, the Lateral Line, the Deep Front Line, and, by mechanical connection, the Superficial
Front Line. Proper assessment involves weighing an ever-shifting dance of pulls created by a host of myofascial
units across each semi-independent side of the pelvis.
Because of the many pulls and tracks competing to set the position of the ASIS, the SPL does not always win
out in communicating between its upper track (the skull to ribs to hip portion we have just covered) and its lower
track (the 'jump rope' around the arches we are about to cover). Therefore, we often assess and consider these
two halves of the line separately.

후방나선선
나선선 일반적 운동고려사항
나선선은 회전과 비틀림 운동으로 신장되고 관여된다.
토의 1. 상부 나선선과 몸통의 회전자세
복잡한 꼬임과 회전역학을 가지고 있는 상부나선선과 한번만 꼬인 하부나선선은 흔히 분리되어 논의된다.
4개의 경계신호
1) 흉곽에 비해 머리의 위치가 변위 또는 기울었을때
2) 한쪽 어깨가 다른쪽 어깨보다 좀더 앞으로 나왔을때
3) 골반에 비해 외측흉곽이 변위되었을때
4) 흉골과 치골의 방향이지나치게 차이가 날때
(1) shifts or tilts in the head position relative to the rib cage,
(2) one shoulder more forward than the other, (3) lateral rib
cage shifts relative to the pelvis, or (4) differences in the direction
of the sternum and pubis, which usually can also be read
as marked differences in the measurement from one costal
arch (where the outside edge of the rectus abdominis crosses
the costal cartilages) to the opposite ASIS.
토의 2. 나선선과 전방머리자세 head forward posture
잘 이해가 안되네....
전거근의 전방, 중부, 하방섬유에 따른 전방머리자세와의 연관성...
The serratus anterior, as we noted above, is a complex muscle,
a broad combination of a quadrate and triangular muscle that
both stabilizes and controls the shoulder. Earlier in our phylogenetic
history, the serratus was primarily responsible for creating
a sling to support the rib cage within the uprights of the
scapulae (see Ch. 7 or DVD ref: Shoulder and Arm Lines,
3:22-5:07).
The lower slips of serratus definitely belong to the SPL, but
the middle slips form a connection with each other across the
bottom of the sternum, under the pectoralis major, at the level
of the 'bra line'. (See also Appendix 1 - this corresponds to
Schultz's chest band, p. 255) This creates a 'branch line' for
the SPL of interest where you see the ubiquitous forward head
posture.
If we follow this line from the midline just above the xiphoid
process, around the middle slips of the serratus to the middle
of the rhomboid and across to the splenius capitis on the opposite
side, we end up on the skull. To see or feel this for yourself
- and it is worthwhile to understand this pattern - take a six- to
eight-feet strip of fabric like a yoga belt or a length of gauze,
stand behind your model, place the middle of the strip above
the xiphoid and bring the two ends behind the model, crossing
them up between the shoulder blades to 'attach' them to the
skull by holding them there with your hands. (It is possible to do
this on yourself, but difficult to avoid getting tangled up.)
Now have the model jut their head forward of the rest of
the body. Feel the strip tighten and pull back on the sternum.
So many of those with forward head posture also have the
tight chest band, and this is a major avenue for the transmission
of the strain. If you wish to see the chest band loosen its
hold on your model's breathing, get the head back up on top
of the body. That will ease this line and help restore the full
excursion of the chest in breathing.
토의 3. 발아치와 골반경사 foot arches and pelvic tilt
발 아치체계에서 전경골근과 장비골근이 함께 등자(stirrup)을 형성한다는 것은 오래전부터 인식해왔다. 전경골근은 내측세로아치의 약한부분을 당겨올리고, 장비골근은 외측아치의 중심인 입방골을 지지하고 이들은 같이 횡아치의 근위부가 내려앉는 것을 예방한다.
It has long been recognized that the tibialis anterior and the fibularis (peroneus) longus together form a 'stirrup' under the
arch system of the foot. The tibialis pulls up on a weak section of the medial longitudinal arch, the fibularis tendon supports the cuboid, the keystone of the lateral arch, and together they help to prevent the proximal part of the ransverse arch from dropping (see Fig. 6.15).
Furthermore, there is a reciprocal relationship between the : a lax (or 'locked long') tibialis coupled with a contracted
(or 'locked short') fibularis will contribute to an everted (pronated) , with the tendency toward a drop in the medial
arch (see Fig. 6.16). The opposite pattern, a shortened tibialis a strained fibularis, tends to create an inverted (supinated) foot with an apparently high arch and the weight shifted laterally on the foot.
