Channel Anatomy of the Neck — Which Channel Hurts?颈部经络解剖——哪条经络受阻?
The neck is the most channel-dense region of the body — every primary Yang channel ascends through the neck and cervical spine. Pain location directly identifies the involved channel:
Posterior midline (Du Mai / GV): Nuchal pain, stiffness along the spinous processes, occipital headache. Du Mai governs all Yang — blockage here affects the entire Yang axis.
Posterior paravertebral (Bladder channel): Pain along the erector spinae, lateral to the spinous processes. BL10, BL11, BL12 are the key points. This is the most common pattern in cervical spondylosis.
Lateral neck / SCM (Gallbladder / San Jiao / Small Intestine): Lateral neck pain, radiating to the temporal region (GB), to the shoulder and upper arm (SI, SJ). Unilateral stiffness with limited rotation.
Anterior neck / SCM (Stomach channel): Anterior cervical pain, throat tension, clavicular pain. Less common in pure musculoskeletal presentations.
Clinical rule: Pain on rotation → GB/SI/SJ channels (lateral). Pain on extension → BL channel (posterior). Pain on flexion → rarely primary neck; consider anterior disc or visceral referral. Pain in a dermatomal distribution → nerve root compression (assess C-spine levels C4–C8).
颈部是全身经络最密集的区域——每条主要阳经均上行经过颈部和颈椎。疼痛位置直接识别受累经络:
后正中线(督脉):项部疼痛,沿棘突僵硬,枕部头痛。督脉统领诸阳——阻滞于此影响整个阳气轴。
后旁椎区(膀胱经):沿竖脊肌、棘突外侧疼痛。天柱(BL10)、大杼(BL11)、BL12为关键穴位。这是颈椎病最常见的模式。
颈侧/胸锁乳突肌区(胆经/三焦/小肠):颈侧疼痛,放射至颞区(胆),至肩和上臂(小肠、三焦)。单侧僵硬伴旋转受限。
颈前/胸锁乳突肌(胃经):颈前疼痛,咽喉紧张,锁骨疼痛。纯骨骼肌肉表现中较少见。
临床规律:旋转时痛→胆/小肠/三焦经(侧面)。后伸时痛→膀胱经(后面)。前屈时痛→很少为原发颈部;考虑前部椎间盘或内脏牵涉。皮节分布疼痛→神经根压迫(评估C4–C8节段)。
Examination Sequence: Observation → ROM → Palpation → Special Tests → Neuro Screen检查顺序:视诊→活动度→触诊→特殊试验→神经筛查
Always examine before treating. Palpation findings directly guide the trigger point and FSN needle placement. The special tests determine whether this is a pure myofascial problem, a joint problem, a disc problem, or a radiculopathy — each requires a different treatment approach.
始终在治疗前检查。触诊发现直接指导激痛点和浮针的进针位置。特殊试验决定这是纯肌筋膜问题、关节问题、椎间盘问题还是根性病变——每种需要不同的治疗方法。
Step 1 — Observation第一步——视诊
Posture姿势Forward head posture (FHP): ear lobe in front of the acromion? Every 2.5cm of forward head shift adds ~10kg of effective load to the cervical spine. Lateral tilt: tight ipsilateral scalenes or SCM. Elevated shoulder: upper trapezius spasm or levator scapulae shortening — this is the "carrying tension" posture, classic Liver Qi stagnation manifesting structurally.头前移姿势(FHP):耳垂在肩峰前方?头部每前移2.5cm,颈椎有效负荷增加约10kg。侧向倾斜:同侧斜角肌或胸锁乳突肌紧张。肩部抬高:上斜方肌痉挛或肩胛提肌缩短——这是"紧绷"姿势,肝气郁滞在结构上的表现。
Step 2 — Cervical ROM第二步——颈椎活动度(正常值)
Flexion / Extension前屈/后伸Flexion 45°, Extension 45°. Pain on extension: facet joint compression or posterior disc — BL channel. Pain on flexion: anterior disc or longus colli strain. Loss of extension is the most functionally significant in cervical spondylosis.前屈45°,后伸45°。后伸时痛:关节突关节压迫或后部椎间盘——膀胱经。前屈时痛:前部椎间盘或颈长肌扭伤。后伸丧失在颈椎病中功能意义最重大。
Rotation旋转Normal 70–80° each side. Asymmetric rotation with ipsilateral pain: ipsilateral facet joint compression or SCM/upper trapezius MTrP. Asymmetric rotation with contralateral pain: contralateral scalene or levator scapulae tightness preventing rotation.正常每侧70–80°。同侧旋转伴同侧疼痛:同侧关节突关节压迫或胸锁乳突肌/上斜方肌MTrP。同侧旋转伴对侧疼痛:对侧斜角肌或肩胛提肌紧张阻止旋转。
Lateral Flexion侧屈Normal 45° each side. Painful lateral flexion toward the side of pain: ipsilateral facet compression. Painful lateral flexion away from pain (contralateral): muscle or soft tissue tightness on the ipsilateral side — scalenes, SCM, upper trapezius.正常每侧45°。向痛侧侧屈痛:同侧关节突关节压迫。向无痛侧侧屈痛(对侧):同侧肌肉或软组织紧张——斜角肌、胸锁乳突肌、上斜方肌。
Step 3 — Palpation: Key MTrP Locations and Their Referral Patterns第三步——触诊:关键MTrP位置及其牵涉痛模式
Upper Trapezius上斜方肌Location: mid-belly of the upper trapezius, between C7 and the acromion. Palpate as a pincer grip or flat palpation. Active MTrP refers: up the lateral neck, over the ear, to the temporal region and eye (mimics tension headache or migraine). This single MTrP accounts for a significant proportion of "headaches" that are actually cervicogenic. The "carrying tension in your shoulders" sensation is this MTrP. In TCM: upper trapezius is the primary Shaoyang channel (GB/SJ) muscle — stagnation here reflects Liver Qi stagnation creating channel blockage at the GB21 territory.位置:上斜方肌腹部中点,C7与肩峰之间。钳形抓握或平面触诊。活跃MTrP牵涉:向上至颈侧,经过耳部,至颞区和眼(模仿紧张性头痛或偏头痛)。这个单一MTrP占"头痛"中相当大比例,实际上是颈源性的。"肩部紧绷"感就是这个MTrP。中医:上斜方肌是主要的少阳经(胆/三焦)肌肉——此处瘀滞反映肝气郁滞在GB21区域造成经络阻塞。
Levator Scapulae肩胛提肌Location: lateral neck between C1–C4 transverse processes and the superior angle of the scapula. Palpate laterally with the patient's hand behind their back (unlocks the superior scapular angle). Active MTrP refers: stiff neck, ipsilateral posterior neck pain, and medial scapular border pain — the classic "can't turn my head" pattern. In TCM: this muscle runs along the BL and SI channel territory. MTrP here is the palpable expression of the channel blockage producing cervical rotation restriction.位置:C1–C4横突和肩胛骨上角之间的颈侧。患者手置于背后(解锁肩胛上角)时侧向触诊。活跃MTrP牵涉:颈部僵硬,同侧颈后疼痛,肩胛骨内侧缘疼痛——经典"头无法转动"模式。中医:该肌沿膀胱经和小肠经走行区域。此处MTrP是经络阻塞产生颈椎旋转受限的可触及表现。
SCM — Sternocleidomastoid胸锁乳突肌(SCM)Location: Palpate as a pincer grip along the length of the SCM. Has two heads (sternal and clavicular) each with different referral patterns. Sternal head MTrP: refers to the ipsilateral occiput, across the vertex, to the supra-orbital area (eye pain, "eye headache"), and cheek — classic headache referral. Clavicular head MTrP: refers to the forehead and ear, producing "earache" without pathology and frontal headache. Also: spatial disorientation and dizziness (SCM proprioceptors are critical for postural balance). In TCM: SCM lies along the Stomach channel (ST9 area) — chronic SCM tension reflects Phlegm-stasis in the ST channel affecting the neck-throat-face axis.位置:沿SCM全长行钳形抓握触诊。有两个头(胸骨头和锁骨头),各有不同牵涉模式。胸骨头MTrP:牵涉至同侧枕部,越过头顶,至眶上区域(眼痛,"眼头痛"),和面颊——经典头痛牵涉。锁骨头MTrP:牵涉至前额和耳部,产生无病理基础的"耳痛"和前额头痛。也可产生空间定向障碍和头晕(SCM本体感受器对姿势平衡至关重要)。中医:SCM沿胃经走行(ST9区域)——慢性SCM紧张反映痰瘀在胃经影响颈-喉-面轴线。
Suboccipital Muscles枕下肌群Location: just below the occiput, between the mastoid process and the C2 spinous process. Palpate with the patient supine and head slightly flexed. Four small muscles (rectus capitis posterior major/minor, obliquus capitis superior/inferior). MTrP refers: deep, behind-the-eye headache, "headache inside the skull," visual disturbance (eye-tracking difficulty). In TCM: suboccipital region is the entry point of the Du Mai and GB channel — stagnation here is one of the most common sources of chronic "internal headache." GB20 (Feng Chi — Wind Pool) is located precisely at the lateral edge of this muscle group.位置:枕骨正下方,乳突与C2棘突之间。患者仰卧头部轻度前屈时触诊。四块小肌肉(头后直肌大/小,头斜肌上/下)。MTrP牵涉:眼后深部头痛,"颅骨内头痛",视觉障碍(眼球追踪困难)。中医:枕下区是督脉和胆经的进入点——此处瘀滞是慢性"内部头痛"最常见的来源之一。风池(GB20)(风池)精确位于这组肌肉的外侧缘。
Step 4 — Special Tests第四步——特殊试验
Spurling TestSpurling试验(椎间孔压缩试验)
Procedure: Lateral flexion + rotation to the painful side + gentle downward axial compression on the head.
Positive: Reproduction of the patient's arm/hand symptoms (radicular pain or numbness) — not just neck pain.
Meaning: Cervical nerve root compression (radiculopathy). Positive Spurling = nerve root is involved. Sensitivity ~50%, Specificity ~90% — a positive test is highly significant.
TCM significance: A positive Spurling identifies the neurological layer — the channel blockage has reached the point where it is compressing the nerve root itself (the channel's deepest layer). Treatment must decompress this level.操作:向痛侧侧屈+旋转+轻柔向下轴向压迫头部。
阳性:重现患者手臂/手部症状(根性痛或麻木)——不只是颈痛。
意义:颈神经根压迫(根性病变)。Spurling阳性=神经根受累。灵敏度约50%,特异性约90%——阳性结果高度提示。
中医意义:阳性Spurling识别神经层——经络阻塞已达到压迫神经根本身的程度(经络的最深层)。治疗必须在此层面减压。
Distraction Test颈椎牵张试验Procedure: Cup the patient's occiput and chin, gently lift (distract) the head vertically.
Positive: Relief of arm or neck pain with distraction.
Meaning: Confirms discogenic or foraminal compression (distraction opens the foramen and relieves root compression). Often performed after a positive Spurling to confirm the nerve root mechanism. TCM: distraction temporarily reverses the channel compression — confirms the treatment principle is to open and decompress the channel.操作:托住患者枕部和下颌,轻柔垂直向上牵引头部。
阳性:牵引后手臂或颈部疼痛缓解。
意义:确认椎间盘源性或椎间孔压迫(牵引开放椎间孔,缓解神经根压迫)。通常在Spurling阳性后进行以确认神经根机制。中医:牵引暂时逆转经络压迫——确认治疗原则是开通和减压经络。
Jackson Compression TestJackson压迫试验Procedure: Head lateral flexion to the side of pain, then gentle axial compression (without rotation — distinguishes from Spurling).
Positive: Ipsilateral neck or arm pain reproduced.
Meaning: Facet joint compression on the ipsilateral side. Less specific for radiculopathy than Spurling but identifies the facet joint as a pain source — the Prolotherapy zone for the facet joint capsule.操作:头部向痛侧侧屈,然后轻柔轴向压迫(不旋转——区别于Spurling)。
阳性:重现同侧颈部或手臂疼痛。
意义:同侧关节突关节压迫。对根性病变不如Spurling特异,但识别关节突关节为疼痛来源——关节囊的增生疗法适应区。
Vertebral Artery Test椎动脉试验Procedure: Patient supine. Clinician slowly rotates and extends the head to one side and holds for 30 seconds. Repeat other side.
Positive: Dizziness, nystagmus, visual disturbance, facial tingling, nausea.
Mandatory before ANY cervical manipulation. A positive test is a contraindication to high-velocity cervical manipulation. Acupuncture and gentle mobilisation can generally proceed cautiously. TCM note: a positive test suggests the channel compression has reached the vertebral artery level — especially relevant in elderly patients with cervical spondylosis.操作:患者仰卧。临床医师缓慢将头部旋转和后伸至一侧,保持30秒。另侧重复。
阳性:头晕、眼球震颤、视觉障碍、面部麻刺感、恶心。
任何颈椎手法前必须进行。阳性为高速颈椎手法的禁忌证。针灸和温和活动通常可谨慎进行。中医注意:阳性提示经络压迫已达椎动脉层面——在颈椎病老年患者中尤为相关。
Step 5 — Neurological Screen (C4–C8)第五步——神经筛查(C4–C8)
Dermatomal sensory皮节感觉C4: cape of shoulder. C5: lateral deltoid. C6: thumb and index finger. C7: middle finger. C8: ring and little finger, medial forearm. T1: medial upper arm. Test light touch and pinprick bilaterally. Asymmetric sensory change confirms nerve root level involvement.C4:肩部斗篷区。C5:三角肌外侧。C6:拇指和食指。C7:中指。C8:无名指和小指,前臂内侧。T1:上臂内侧。双侧测试轻触和针刺。不对称的感觉改变确认神经根层次受累。
Myotomal strength肌节肌力C5: shoulder abduction (deltoid). C6: elbow flexion (biceps), wrist extension. C7: elbow extension (triceps), wrist flexion. C8: finger flexion. T1: finger abduction/adduction. Grade 0–5. Weakness below 4/5 = significant motor involvement — refer for further imaging/specialist assessment if progressive.C5:肩外展(三角肌)。C6:肘屈曲(肱二头肌),腕伸展。C7:肘伸展(肱三头肌),腕屈曲。C8:手指屈曲。T1:手指外展/内收。0–5级。肌力低于4/5=显著运动受累——如进行性加重,转诊进一步影像/专科评估。
Deep tendon reflexes深腱反射Biceps (C5/C6), Brachioradialis (C6), Triceps (C7). Reduced reflex = lower motor neuron (nerve root compression at that level). Hyperreflexia or clonus = upper motor neuron (spinal cord involvement — urgent referral).肱二头肌(C5/C6),肱桡肌(C6),肱三头肌(C7)。反射减弱=下运动神经元(该节段神经根压迫)。反射亢进或阵挛=上运动神经元(脊髓受累——紧急转诊)。
