Principles and application of range of motion and stretching in companion animals

The Role of Early Rehabilitation and Functional Electrical Stimulation in Rehabilitation for Cats with Partial Traumatic Brachial Plexus Injury: A Pilot Study on Domestic Cats in Portugal

This prospective observational cohort pilot study included 22 cats diagnosed with partial traumatic brachial plexus injury (PTBPI), aiming to explore responses to an early intensive neurorehabilitation protocol in a clinical setting. This protocol included functional electrical stimulation (FES), locomotor treadmill training and kinesiotherapy exercises, starting at the time with highest probability of nerve repair. The synergetic benefits of this multimodal approach were based on the potential structural and protective role of proteins and the release of neurotrophic factors. Furthermore, FES was parametrized according to the presence or absence of deep pain. Following treatment, 72.6% of the cats achieved ambulation: 9 cats within 15 days, 2 cats within 30 days and 5 cats within 60 days. During the four-year follow-up, there was evidence of improvement in both muscle mass and muscle weakness, in addition to the disappearance of neuropathic pain. Notably, after the 60 days of neurorehabilitation, 3 cats showed improved ambulation after arthrodesis of the carpus. Thus, early rehabilitation, with FES applied in the first weeks after injury and accurate parametrization according to the presence or absence of deep pain, may help in functional recovery and ambulation, reducing the probability of amputation.

Canine Comprehensive Mobility Assessment

A comprehensive mobility assessment goes beyond the orthopedic or neurologic examination for the localization of pathology. This assessment involves attention to the dog's posture and stance, a hands-on examination with special attention to soft tissue structures, and the performance of functional assessments. A comprehensive mobility assessment can guide advanced diagnostic testing as well as providing a foundation in the formulation of a successful treatment plan.

A Systematic Review of Musculoskeletal Mobilization and Manipulation Techniques Used in Veterinary Medicine

Simple Summary

Neck and back pain are common ailments in animals. While there are medical and surgical treatment options available for select patients, conservative care is the most common form of management of pain, stiffness and muscle spasms. Physical therapists, osteopaths and chiropractors use mobilization and manipulation techniques to evaluate and treat muscle and joint problems in both humans and animals, but there seems to be little scientific evidence available to support their use in veterinary medicine. This study reviews the scientific literature with the goal of identifying the clinical indications, dosages, outcome parameters, and efficacy of mobilization and manipulation techniques in dogs and horses. Fourteen articles were included in this review of which 13 were equine and one was a canine study. There was a large variability in the quality of evidence that supports the use of joint mobilization or manipulation in treating pain, stiffness and muscle hypertonicity in horses. Therefore, it was difficult to draw firm conclusions despite all studies reporting positive effects. Future studies need to establish standardized methods to evaluate the optimal dosages of mobilization and manipulation for use in animals.

Abstract

Mobilization and manipulation techniques are often used in small animal and equine practice; however, questions remain concerning indications, dosing and efficacy. A bibliographic search was performed to identify peer-reviewed publications from 1980 to 2020 that evaluated the clinical effects of musculoskeletal mobilization and manipulation techniques in dogs, cats and horses. The search strategy identified 883 papers for review. Inclusion and exclusion criteria were applied. The clinical indications, dosages, outcome parameters, and reported efficacy within each publication were recorded and categorized for comparison with scientific quality assessed according to a standardized grading system. Fourteen articles were included in this systematic review of which 13 were equine and one was a canine study. Seven of these were cohort studies and seven were randomized controlled clinical trials. The canine study involved carpal immobilization-remobilization and all equine studies focused on the effects of passive mobilization (n = 5) or manipulation (n = 8) of the axial skeleton. Study quality was low (n = 4), moderate (n = 7), and high (n = 3) and included a wide array of outcome parameters with varying levels of efficacy and duration of therapeutic effects, which prevented further meta-analysis. Therefore, it was difficult to draw firm conclusions despite all studies reporting positive effects. Optimal technique indications and dosages need to be determined to improve the standardization of these treatment options.

The Effect of Cranial Cruciate Ligament Rupture on Range of Motion in Dogs

Range of motion (ROM) is a measure often reported as an indicator of joint functionality. Both the angle of extension and that of flexion were measured in 234 stifle joints of dogs with cranial cruciate ligament (CCL) rupture. The aims of this study were to investigate the correlation between CCL rupture and alterations in the range of stifle joint motion and to determine whether there was a prevalence modification of one of the two angles. All the extension and flexion angles were obtained from clinical records and were analysed in various combinations. A significant relationship was found between normal angles and abnormal angles; concerning the reduction in the ROM, a significant prevalence in the alteration extension angle was found. Of the 234 stifles, 33 (13.7%) were normal in both angles. These results could offer important insights regarding the influence of CCL rupture on compromising the ROM. This awareness could be a baseline for understanding the ability of surgical treatment to restore one angle rather than another angle, to address the choice of treatment and to help physiotherapists in their rehabilitation program.

Rehabilitation of companion animals following orthopaedic surgery

Physical therapy and rehabilitation following orthopaedic surgery in companion animals have become more common and new advancements in this field have been made in recent years. Surgery alone may not return the animal to its previous physical activity or work-related tasks, whether due to concurrent soft tissue trauma, arthrogenic muscle inhibition or osteoarthritis. Rehabilitation therapies following surgery can restore function as well as strength, coordination and balance. Many simple techniques such as cryotherapy and passive range of motion exercises have been shown to improve outcomes following musculoskeletal procedures and may help restore function as well as reduce pain and facilitate healing. Some techniques are more useful during different stages in order to achieve optimum tissue healing and recovery of function. During the first 72 hours, rehabilitation should focus on reduction of inflammation and pain, maintaining joint nutrition and range of motion, and stimulating vascularisation and healing; and may include cryotherapy, passive range of motion exercises, massage and therapeutic exercises. Following the initial recovery period, the goals of rehabilitation also include restoring strength, balance and normal gait patterns, as well as recovery of function. During this period the focus of therapy may shift toward therapeutic exercises, aquatic therapy and increasing activity in the animal. Therapeutic modalities such as neuromuscular electrical stimulation, photobiomodulation (laser therapy), therapeutic ultrasound and extracorporeal shock wave therapy have been reported to reduce pain and inflammation, enhance healing and reduce recovery time in the early and late stages following orthopaedic surgery.

Modalidades fisioterapêuticas na reabilitação de cães com doença do disco intervertebral toracolombar submetidos à cirurgia descompressiva: 30 casos (2008-2016)

RESUMO Este estudo retrospectivo teve como objetivo demonstrar as modalidades fisioterapêuticas empregadas no tratamento de cães com doença do disco intervertebral (DDIV) toracolombar após descompressão cirúrgica da medula espinhal, bem como relatar os fatores que determinaram as alterações das modalidades. Foram incluídos 30 cães que apresentavam sinais neurológicos desde paraparesia ambulatória a paraplegia com dor profunda na primeira sessão de fisioterapia. As modalidades utilizadas nos protocolos de todos os pacientes foram a crioterapia, massagem, alongamento passivo, movimentação passiva articular, estímulo do reflexo flexor e estimulação elétrica neuromuscular. A inclusão ou exclusão de exercícios terapêuticos, como a tipoia corporal, a plataforma proprioceptiva circular, a natação, a hidroesteira, os obstáculos e a caminhada em colchão, foi de acordo com a evolução clínica e a adaptação de cada paciente. Oitenta por cento (80%) dos cães alteraram o grau de disfunção neurológica antes de iniciar a fisioterapia e 93% retornaram à habilidade de caminhar (paraparesia ambulatória) ao final da fisioterapia. O número de sessões e o tempo de recuperação foram maiores quanto pior foi o grau de lesão do paciente.

Complex angular and torsional deformities (distal femoral malunions)

Objective: To describe the surgical technique of complex distal femoral deformity correction with the aid of stereolithography apparatus (SLA) biomodels, stabilized with locking plate fixation.

Methods: Full-size replica epoxy bone bio-models of the affected femurs (4 dogs/5 limbs) were used as templates for surgical planning. A rehearsal procedure was performed on the biomodels aided by a guide wire technique and stabilized with locking plate fixation. Surgery performed in all dogs was guided by the rehearsal procedure. All pre-contoured implants were subsequently used in the definitive surgical procedure with minimal modification.

Results: All dogs had markedly improved, with near normal functional outcomes; all but one had a mild persistent lameness at the final in-hospital follow-up examination (mean: 54.4 weeks; range: 24–113 weeks after surgery). All femurs healed without complications (mean: 34 weeks, median: 12 weeks; range: 8–12 weeks for closing osteotomies, and 26–113 weeks for opening wedge osteotomies). Long-term follow-up examination (mean: 28.6 months; range: 5–42 months) revealed all but one owner to be highly satisfied with the outcome. Complications were observed in two dogs: prolonged tibiotarsal joint decreased flexion that resolved with physical therapy. In one of these dogs, iatrogenic transection of the long digital extensor tendon was repaired, and the other had a peroneal nerve neurapraxia.

Clinical significance: Stereolithography apparatus biomodels and rehearsal surgery simplified the definitive surgical corrections of complex femoral malunions and resulted in good functional outcomes.

Use of adjunctive prednisolone in the management of a cat with bilateral quadriceps contracture following trauma

Case summary

A 6-month-old cat was successfully treated for bilateral quadriceps contracture. Conventional treatments including surgery, dynamic flexion apparatus and physical therapy along with analgesics and non-steroidal anti-inflammatory drugs resulted in temporary clinical improvement that was relapsing. The initiation of supplementary corticosteroid treatment with prednisolone coincided with an immediate and sustained clinical improvement and long-term resolution.

Relevance and novel information

Successful treatment of bilateral quadriceps contracture has not previously been reported in a cat. Quadriceps contracture remains a challenging condition to treat with some cases unresponsive to therapy. Systemic prednisolone treatment appeared to be of benefit in the management of this case and may have a role in some cats where muscle contracture appears relapsing in nature. Further prospective investigations in cats with muscle contracture, including muscle biopsies of affected cats, are warranted.
