Targeting Weakness With a Combination of Isotonic Exercises in Dermatomyositis With Polyneuropathy: A Case Report.

Dermatomyositis, an autoimmune inflammatory myositis commonly linked to polymyositis, is marked by inflammatory and degenerative transformations impacting muscles, skin, limb girdles, the neck, and the pharynx. These changes result in symmetrical weakness and diverse levels of muscle atrophy. Uncommonly, the condition may impact the esophagus, lungs, and heart. While dermatomyositis is believed to involve genetic, immunological, and environmental factors, its precise etiology remains elusive. Typically, the classical presentation involves a symmetrical proximal myopathy alongside dermatological manifestations such as a purplish-red rash affecting the face, arms, hands, legs, and other areas. Additional symptoms may include dysphagia, myalgia, fever, and weight loss. The primary objectives of managing dermatomyositis are to address muscular weakness, skin manifestations, and any underlying health concerns. Integral to this management is the utilization of physical therapy and rehabilitation interventions. This study introduces a 23-year-old female patient with a noteworthy medical history covering a duration of two months. The patient reported a chief complaint of persistent thigh pain and a concurrent complaint concerning bilateral weakness in upper and lower extremities. Furthermore, the patient faced the additional challenge of difficulty swallowing. Intriguingly, the patient's clinical presentation was marked not only by the aforementioned symptoms but also by the development of a distinctive facial rash. This facial rash was accompanied by symptoms of stiffness in both small and large joints and a reduction in the range of affected joints. The physiotherapeutic assessment revealed quadriparesis of bilateral upper and lower limbs. The rehabilitation programme for the patient was planned by targeting proprioceptors to increase dynamic trunk balance in patients with DM. The Proprioceptive Neuromuscular Facilitation (PNF) technique employs diagonal movement patterns, thereby proving instrumental in enhancing the patient's daily activities. This methodology serves to optimize the individual's capacity to execute routine daily tasks, promoting independence in their daily life. An investigation like the Nerve Conduction Velocity (NCV) report shows the absence of motor excitation, suggesting motor axonal neuropathy. This approach, comprising isometric, concentric, and eccentric contraction exercises, demonstrated efficacy in mitigating muscular weakness, enhancing motor function, and alleviating the diverse symptoms associated with this condition.
