“…As stated, these similarities can be interpreted as compensatory changes in response to arthralgia and limb deformations. Furthermore, the weakness and atrophy of the calf muscles could be attributed even to the arthrogenic muscle inhibition (AMI), a presynaptic reflex inhibition of the periarticular musculature elicited by abnormal input to the joint, such as swelling and pain [ 17 ], although no pain or ankle impairment that could account for this condition was present in the two children.…”

Gait Alterations in Two Young Siblings with Progressive Pseudorheumatoid Dysplasia

Progressive pseudorheumatoid dysplasia (PPRD) is an autosomal recessive inherited skeletal dysplasia characterized by progressive non-inflammatory arthropathy affecting primarily the articular cartilage. Currently, little is known about the functional musculoskeletal aspects of these patients. In particular, an abnormal gait pattern has been described, without a clear hypothesis of the underlying causes in terms of muscular activity. This study presents the case of two siblings, 4 and 9 years old, a boy and a girl, respectively, suffering from PPRD at different stages of the disease. In addition to the clinical assessment, an instrumental gait analysis was performed. Swelling of the interphalangeal finger joints and fatigue were present in both cases. Gait abnormalities consisted of a relevant reduction in the ankle plantarflexion in the terminal phase of the gait cycle, associated with reduced gastrocnemius EMG activity and increased activity of the tibialis anterior, resulting in overloading at the initial peak of ground reaction forces. Gait anomalies observed were similar in both siblings with PPRD, although at different ages, and confirm walking patterns previously described in the literature. The calf muscle strength deficit and reduced activity during the stance phase of gait present in these two siblings indicate the typical absence of the propulsive phase. A stomping gait pattern, with the foot striking the ground hard on each step, was originally described. Further neurophysiological investigations are required to determine the origin of muscle weakness.

“…Motor Imagery. Motor imagery, mental practice/simulation of motor actions, has been shown to increase excitability 170 and activation 171 of neurons within the motor cortex and spinal cord [172][173][174] in healthy individuals. Motor imagery techniques have been successfully applied poststroke in conjunction with traditional therapies to improve upper-extremity function, 175,176 but significant heterogeneity in the parameters/approach and population characteristics may contribute to inconsistent results.…”

“…177 Although not studied as much in orthopedic rehabilitation, researchers using an ankle effusion model demonstrated the ability of motor imagery to directly enhance motor neuron pool excitability. 172 Furthermore, a randomized controlled trial found that 4 weeks of motor imagery practice in conjunction with standard of care rehabilitation preserved quadriceps strength following total knee arthroplasty. 178 Considerations for the near-limitless variability in parameters (eg, supervision, guided/unguided, location, body position, perspective, focus, length of practice, and more) of motor imagery must be made when incorporating this intervention in treatment.…”

“…Although the mechanisms are not well understood, corticospinal excitation occurs with motor imagery, most notably throughout the mirror neuron system (including the primary motor cortex, premotor and supplementary motor areas, cingulate cortex, parietal cortex, basal ganglia, and cerebellum) 180 and extends down to spinal circuits. 172 Practice over time may enhance cortically driven muscle activity and reestablish quadriceps excitability similar to EMG biofeedback techniques.…”

Context: Arthrogenic muscle inhibition (AMI) impedes the recovery of muscle function following joint injury, and in a broader sense, acts as a limiting factor in rehabilitation if left untreated. Despite a call to treat the underlying pathophysiology of muscle dysfunction more than three decades ago, the continued widespread observations of post-traumatic muscular impairments are concerning, and suggest that interventions for AMI are not being successfully integrated into clinical practice. Objectives: To highlight the clinical relevance of AMI, provide updated evidence for the use of clinically accessible therapeutic adjuncts to treat AMI, and discuss the known or theoretical mechanisms for these interventions. Evidence Acquisition: PubMed and Web of Science electronic databases were searched for articles that investigated the effectiveness or efficacy of interventions to treat outcomes relevant to AMI. Evidence Synthesis: 122 articles that investigated an intervention used to treat AMI among individuals with pathology or simulated pathology were retrieved from 1986 to 2021. Additional articles among uninjured individuals were considered when discussing mechanisms of effect. Conclusion: AMI contributes to the characteristic muscular impairments observed in patients recovering from joint injuries. If left unresolved, AMI impedes short-term recovery and threatens patients’ long-term joint health and well-being. Growing evidence supports the use of neuromodulatory strategies to facilitate muscle recovery over the course of rehabilitation. Interventions should be individualized to meet the needs of the patient through shared clinician–patient decision-making. At a minimum, we propose to keep the treatment approach simple by attempting to resolve inflammation, pain, and effusion early following injury.

“…20 Known without any adverse effect, this practice may be combined with sensory modalities or used in conjunction with other disinhibitory interventions targeting different neural pathways to achieve the ideal therapeutic goal for AMI treatment. 15,28 Interestingly, the effect of a novel neuromotor reprogramming (NR) treatment based on the use of proprioceptive sensations associated with motor imagery and low frequency sounds (LFS) has not been studied in AMI after knee injuries. Fundamentally, motor imagery and movement execution share substantial overlap of active brain regions that may minimize AMI and quadriceps dysfunction.…”

Background: Persistent weakness of the quadriceps muscles and extension deficit after knee injuries are due to specific alterations in neural excitability - a process known as arthrogenic muscle inhibition (AMI). The effects of a novel neuromotor reprogramming (NR) treatment based on the use of proprioceptive sensations associated with motor imagery and low frequency sounds have not been studied in AMI after knee injuries. Hypothesis: This study aimed to assess quadriceps electromyographic (EMG) activity and the effects on extension deficits in persons with AMI who completed 1 session of NR treatment. We hypothesized that the NR session would activate the quadriceps and improve extension deficits. Study Design: Case series. Level of Evidence: Level 4. Methods: Between May 1, 2021 and February 28, 2022, patients who underwent knee ligament surgery or sustained a knee sprain with a deficit of >30% of the vastus medialis oblique (VMO) on EMG testing in comparison with the contralateral limb after their initial rehabilitation were included in the study. The maximal voluntary isometric contraction of the VMO measured on EMG, the knee extension deficit (distance between the heel and the table during contraction), and the simple knee value (SKV) were assessed before and immediately after completion of 1 session of NR treatment. Results: A total of 30 patients with a mean age of 34.6 ± 10.1 years (range, 14-50 years) were included in the study. After the NR session, VMO activation increased significantly, with a mean increase of 45% ( P < 0.01). Similarly, the knee extension deficit significantly improved from 4.03 ± 0.69 cm before the treatment to 1.93 ± 0.68 after the treatment ( P < 0.01). The SKV was 50 ± 5.43% before the treatment, and this increased to 67.5 ± 4.09% after the treatment ( P < 0.01). Conclusion: Our study indicates that this innovative NR method can improve VMO activation and extension deficits in patients with AMI. Therefore, this method could be considered a safe and reliable treatment modality in patients with AMI after knee injury or surgery. Clinical Relevance: This multidisciplinary treatment modality for AMI can enhance outcomes through the restoration of quadriceps neuromuscular function and subsequent reduction of extension deficits after knee trauma.
