We present a case report that a longitudinal calf MR evaluation was performed for a patient with Charcot-Marie-Tooth disease who underwent bilateral reconstructive foot surgeries. A 39 years-old female was referred to our department because of severe bilateral cavus foot deformities and difficulty to walk. On radiological findings, severe bilateral cavus foot deformities were confirmed. On MR findings, fatty infiltrations were detected in the wide range of bilateral lower leg compartments. Difficulty to walk aggravated despite of the conservative treatment, so bilateral reconstructive foot surgeries were performed. She acquired plantigrade and better walking function postoperatively. Two years after surgery, no recurrence of cavus foot deformity was observed, but claw toe deformities and fatty infiltrations were mildly progressing. Since CMT is slowly progressive, we need to conduct a careful follow-up.
A 70-year-old woman with rheumatoid arthritis underwent above-knee amputation due to osteomyelitis after right total knee arthroplasty. After the surgery, the patient started rehabilitation for wearing a prosthetic leg. However, the patient could not wear the prosthesis by herself because of severe upper limb impairment due to bilateral finger joint deformity and muscle weakness associated with the rheumatoid arthritis. Therefore, physical therapists and prosthetists/orthotists collaborated to determine movements that could be performed, even with muscle weakness, using assistive devices such as a Velcro strip handle with the prosthesis and a prosthetic liner stand. Subsequently, repetitive training was performed in an environment similar to the setting of the patient's prosthesis use at home. Consequently, although no change in upper limb function was observed, the patient had increased independence during prosthesis attachment. As she had difficulty wearing and removing her trousers/underwear while wearing the prosthesis, she performed movements using assistive devices and made changes to the order of movements. Six months after the surgery, she could wear the prosthesis and perform self-care correctly by herself and return home. Therefore, to maximize function that enables independence after amputation, helping patients learn how to put on the prosthesis using a team approach is important.
We report a case of a patient with chronic stroke who improved his gait ability through weekly gait training using Gait Exercise Assist Robot (GEAR). A man in his 70s, who developed cerebral infarction 27 years ago, presented with right-sided hemiplegia. Before gait training, the patient's gait ability was assessed to be independent, but poor toe clearance was observed on the paralyzed side during the swing phase. Therefore, we started gait training using GEAR with the goal of improving his gait pattern. The patient underwent gait training using GEAR for 20 min/day, 1 day/week for 12 weeks, wherein the treadmill speed was increased as much as possible in order to improve the swing of the paralyzed lower limbs, and the visual and auditory feedback functions were also used to promote the load and swing of the paralyzed lower limbs. As a result, the overground gait velocity, Timed Up and Go Test, and 6-minute walking distance increased after 4 weeks. However, poor toe clearance was observed on the paralyzed side during the swing phase even after 12 weeks of the training. These results suggest that 4 weeks of gait training using GEAR (performed only 1 day/week) may effectively improve the gait ability of patients with chronic stroke. On the other hand, no improvement in gait pattern was observed, and further investigation is required in the future.
