“…The neck is linked biomechanically and neurologically to the upper limbs, and yet, we know little about the mechanisms by which altered sensory feedback from the neck due to pain, fatigue, and altered posture affects upper limb sensorimotor integration (SMI) and the ability to learn new motor skills [ 1 – 4 ]. Motor learning refers to the acquisition or improvement of a motor skill with practice [ 5 ].…”

Subclinical recurrent neck pain and its treatment impacts motor training-induced plasticity of the cerebellum and motor cortex

The cerebellum processes pain inputs and is important for motor learning. Yet, how the cerebellum interacts with the motor cortex in individuals with recurrent pain is not clear. Functional connectivity between the cerebellum and motor cortex can be measured by a twin coil transcranial magnetic stimulation technique in which stimulation is applied to the cerebellum prior to stimulation over the motor cortex, which inhibits motor evoked potentials (MEPs) produced by motor cortex stimulation alone, called cerebellar inhibition (CBI). Healthy individuals without pain have been shown to demonstrate reduced CBI following motor acquisition. We hypothesized that CBI would not reduce to the same extent in those with mild-recurrent neck pain following the same motor acquisition task. We further hypothesized that a common treatment for neck pain (spinal manipulation) would restore reduced CBI following motor acquisition. Motor acquisition involved typing an eight-letter sequence of the letters Z,P,D,F with the right index finger. Twenty-seven neck pain participants received spinal manipulation (14 participants, 18–27 years) or sham control (13 participants, 19–24 years). Twelve healthy controls (20–27 years) also participated. Participants had CBI measured; they completed manipulation or sham control followed by motor acquisition; and then had CBI re-measured. Following motor acquisition, neck pain sham controls remained inhibited (58 ± 33% of test MEP) vs. healthy controls who disinhibited (98 ± 49% of test MEP, P<0.001), while the spinal manipulation group facilitated (146 ± 95% of test MEP, P<0.001). Greater inhibition in neck pain sham vs. healthy control groups suggests that neck pain may change cerebellar-motor cortex interaction. The change to facilitation suggests that spinal manipulation may reverse inhibitory effects of neck pain.

“…Eight were cross-sectional studies and ten were case series. The cross-sectional studies compared healthy participants and participants with neck pain and/or injury (11)(12)(13)(20)(21)(22)(23)(24); and the case series assessed a healthy cohort in pre-test/post-test studies (14,(25)(26)(27)(28)(29)(30)(31)(32)(33).…”

“…This classification is a widely accepted system for describing the different levels of dysfunction and symptomatology for whiplash. Participants for the majority of studies were predominantly aged 18-45 years (15/18, 83 %) (11,13,14,20,(22)(23)(24)(25)(26)(27)(29)(30)(31)(32)(33) with 3/18 (20%) including participants who were over 45 years old (12,21,28). Information was also presented on gender in 15/18 studies (83%) (11-13, 20-25, 28-33), handedness was reported in 14/18 (78%) (11,13,(20)(21)(22)(25)(26)(27)(28)(29)(30)(31)(32)(33) studies and dominant upper limb reported as used in performance of upper limb kinesthetic tasks by all participants in 13/18 studies (72%) (11,(21)(22)(23)(25)(26)(27)(28)(29)(30)(31)(32)(33).…”

Does My Neck Make Me Clumsy? A Systematic Review of Clinical and Neurophysiological Studies in Humans

et al. 2021

Introduction: Clumsiness has been described as a symptom associated with neck pain and injury. However, the actuality of this symptom in clinical practice is unclear. The aim of this investigation was to collect definitions and frequency of reports of clumsiness in clinical studies of neck pain/injury, identify objective measures of clumsiness and investigate the association between the neck and objective measures of clumsiness.Methods: Six electronic databases were systematically searched, records identified and assessed including a risk of bias. Heterogeneity in designs of studies prevented pooling of data, so qualitative analysis was undertaken.Results: Eighteen studies were retrieved and assessed; the overall quality of evidence was moderate to high. Eight were prospective cross-sectional studies comparing upper limb sensorimotor task performance and ten were case series involving a healthy cohort only. Clumsiness was defined as a deficit in coordination or impairment of upper limb kinesthesia. All but one of 18 studies found a deterioration in performing upper limb kinesthetic tasks including a healthy cohort where participants were exposed to a natural neck intervention that required the neck to function toward extreme limits.Conclusion: Alterations in neck sensory input occurring as a result of requiring the neck to operate near the end of its functional range in healthy people and in patients with neck pain/injury are associated with reductions in acuity of upper limb kinesthetic sense and deterioration in sensorimotor performance. Understanding the association between the neck and decreased accuracy of upper limb kinesthetic tasks provide pathways for treatment and rehabilitation strategies in managing clumsiness.

“…Of interest, this more dramatic head positioning during passive shoulder elevation corresponded with greater trunk movement and perception of a higher shoulder during passive shoulder elevation. 25 Guerraz et al 27 found that head posture greatly impacted the ability of participants to replicate an object using simple arm tracing. For this study, participants lay supine and were asked to view an object and then trace the shape of this object with their unseen index finger using elbow and shoulder movements.…”

“…Notably, the participants perceived the tracing as being in line with their body, although the traces were biased by the head tilt. 27 A recent study found that changing visual feedback altered the amount of pain-free neck rotation in a group of chronic neck pain patients. 28 This indicates an increased reliance on visual input in this group, possibly because their internal body schema or body map is not accurately calibrated, leading to altered integration of sensory input.…”
