Whiplash

“The obliquus capitis inferior remains relatively immobile during traumatic events, like whiplash injuries, placing strain as a tethering point on the greater occipital nerve.”

Editorial note: Trauma leads to irritation, inflammation, and loss of neuroplasticity i.e., (adhesions). Check out this tutorial video on how to use greater occipital nerve flossing to mitigate this process.

Extremity Pain

A new JMPT study published by the McKenzie Institute director of education concluded that, on average, 43.5% of extremity pain originates from the (asymptomatic) spine. Here’s their joint-by-joint breakdown of spinally-referred pain:

  • Shoulder pain – 47%
  • Elbow pain – 44%
  • Wrist/Hand pain – 38%
  • Hip pain – 71% 
  • Knee – 25%
  • Ankle/Foot – 29%

Rotator Cuff

A study published in The Journal of Arthroscopic & Related Surgery concluded that a single rotator cuff corticosteroid injection (in the year before surgery) is associated with 1.3- 2.8 times increased risk of needing revision rotator cuff repair. The study further concluded that caution should be taken when deciding to inject a patient, and this treatment should be withheld if a rotator cuff repair is to be performed within the following six months.

Shoulder Impingement

“Individuals with shoulder impingement had a greater thoracic kyphosis and less extension ROM than…healthy controls. These results suggest that clinicians could consider addressing the thoracic spine in patients with SIS [shoulder impingement syndrome].”

Hunter DJ, Rivett DA, McKiernan S, Smith L, Snodgrass SJ. Relationship Between Shoulder Impingement Syndrome and Thoracic Posture. Phys Ther. 2019 Dec 11. pii: pzz182. doi: 10.1093/ptj/pzz182. Link

Shoulder Impingement

“35% of the patients with shoulder anterior impingement syndrome (SAIS) had cervical nerve root compression on the same side. Cervical radiculopathy and shoulder impingement syndrome can be easily confused. Although both diseases can occur with different mechanisms, we believe that there is a cause and effect relationship between them.”

The arm squeeze test is a useful 2-second assessment to help identify cervically-referred shoulder pain.

Carpal Tunnel Syndrome

“Manual therapy, including desensitization maneuvers of the central nervous system, has been found to be equally effective but less costly (i.e., more cost-effective) than surgery for women with CTS.”

Link

Carpal Tunnel Syndrome

A 6-month follow-up of 107 carpal tunnel syndrome patients from two prior RCT’s concluded:

“The use of manual therapy based on neurodynamic techniques maintains the beneficial effects 6 months after therapy in CTS patients.” (This finding applied to pain reduction, symptom severity, and strength improvement)

Hand Osteoarthritis

“We found that neurodynamic mobilizations immediately decreased hypersensitivity in patients with hand OA, however differences were no longer present at 3-months. The results suggest these techniques may have some limited value in the short-term.”

Infantile Colic

“Sixteen systematic reviews were identified. Probiotics, fennel extract, and spinal manipulation show promise to alleviate symptoms of colic, although some concerns remain.”

Lumbar Disc Herniation

A study reported in the Global Spine Journal reported that the percentage of the spinal canal occupied by a herniated disc does not predict which patients will fail nonoperative treatment and require surgery.

Schmorl’s Nodes

A study of 478 random subjects revealed lumbar vertebral endplate defects in 63.0% of subjects. The presence of endplate defects was associated with 1.64 times increased risk of lifetime back pain.

LBP

BMC Research Notes: “Subjects with vitamin D deficiency or insufficiency were (2.3 times) more likely to exhibit LBP than subjects with normal serum 25-hydroxivitamin D3 concentration.”

Sciatica

“On a sport-specific level, running and cycling were associated with less radiating and non-radiating LBP. In adulthood, the diversity of sport activities, particularly participation in endurance sports, may be associated with less radiating and non-radiating LBP.”

Greater Trochanteric Pain Syndrome

“Magnetic resonance imaging of 16 women with greater trochanteric pain syndrome (GTPS) and 15 asymptomatic controls was undertaken. Significantly smaller muscle volumes were identified in the symptomatic group for the gluteus maximus, gluteus medius, and gluteus minimus. There was no difference in TFL volume. Gluteal muscle atrophy and fatty infiltration in women with GTPS suggests [the gluteal muscles) may be an important target for rehabilitation.”

Patellofemoral Pain Syndrome (PFPS)

The American Journal of Sports Medicine: “A single session of gait retraining using a 10% increase in step rate resulted in significant improvements in running kinematics, pain, and function in runners with patellofemoral pain. These improvements were maintained at 3-month follow-up.”

Trigger Points

Ischemic compression vs. dry needling for suboccipital trigger points: “Both interventions could reduce headache symptoms, pressure-point thresholds, and trigger point area. Neither intervention was found to be superior to the other in short-term follow-up. Ischemic compression may be preferred since it has fewer unwanted side effects compared to dry needling.”

Orthotic Clinical Prediction Rule

A BMC Musculoskeletal Disorders study identified five predictors for determining which plantar heel pain patients may benefit from custom foot orthotics:

  • “Average pain intensity decreased by over 1.5 points with a trial of anti-pronation taping
  • Range of ankle plantarflexion >54 degrees
  • Strength of ankle plantar flexors on the symptomatic side was equal to or stronger than that on the other side
  • Range of hip internal rotation <39 degrees
  • Range of hip external rotation >45 degrees

The presence of three or more predictors increased the rate of achieving positive outcome (with custom orthotics) from 66 to 89%.”Biomechanical Anti-Pronation Taping (BAPT)

Biomechanical anti-pronation taping (BAPT) can be used to help predict a response to custom foot orthotics. BAPT is applied with three strips of rigid 1 ½ inch Leukotape P spanning the arch, and one more spanning the heel.  Begin with the most distal strip first. Anchor the tape on the lateral side first, and slightly “lift” the arch when attaching the medial end, equidistantly up each side of the foot. Apply the more proximal second and third strips in a similar fashion, with approximately ½ inch overlap. The tape is worn for 2-3 days before a response is assessed. Patients who report decreased pain (by more than 1.5 points on a 0-10 VAS scale) have shown a higher likelihood to benefit from custom orthotics. (Wu et al. 2019)
