Evaluation of the Effectiveness of Neuromuscular Electrical Stimulation After Total Knee Arthroplasty: A Meta-Analysis.

OBJECTIVE: The aim of the study was to evaluate the efficacy of the use of the neuromuscular electrical stimulation after total knee arthroplasty. DESIGN: The study used a systematic review of randomized controlled trials (MEDLINE, PubMed, Cochrane Library, and PEDro) using Patient Population or Problem, Intervention, Comparison, Outcomes, Setting approach to formulate the research question, controlled terms, and Boolean operators. Inclusion and exclusion criteria were defined in advance. "Neuromuscular electrical stimulation" and "total knee arthroplasty" were used as keywords. The overall risk of bias was determined according to the following: random sequence generation, concealment, blinding mass of participants and staff, commissioning blind assessment results, incomplete data, and loans received. RESULTS: Of the 36 identified studies, six were included in the review (496 participants). In these studies, one group of patients followed a rehabilitation protocol (control group) and the other followed a rehabilitation program plus a session of neuromuscular electrical stimulation (neuromuscular electrical stimulation group). Patients of neuromuscular electrical stimulation groups got the best scores (timed up and go test, stair climbing test, and walk test). Neuromuscular electrical stimulation benefits were strong in the first postoperative weeks/months and gradually diminished. CONCLUSIONS: Neuromuscular electrical stimulation allows a slightly better functional recovery after total knee arthroplasty, especially in the first period, with more evident benefits in patients with a severe lack of muscular activation. Nevertheless, there is no difference at medium-long term.

Therapeutic ultrasound in physical medicine and rehabilitation: characterization and assessment of its physical effects on joint-mimicking phantoms.

The aim of the study described here was to quantitatively assess thermal and mechanical effects of therapeutic ultrasound (US) by sonicating a joint-mimicking phantom, made of muscle-equivalent material, using clinical US equipment. The phantom contains two bone disks simulating a deep joint (treated at 1 MHz) and a superficial joint (3 MHz). Thermal probes were inserted in fixed positions. To test the mechanical (cavitational) effects, we used a latex balloon filled with oxygen-loaded nanobubbles; the dimensions of the oxygen-loaded nanobubbles were determined before and after sonication. Significant increases in temperature (up to 17°C) with fixed field using continuous waves were detected both in front of and behind the bones, depending on the US mode (continuous wave vs. pulsed wave) and on the treatment modality (fixed vs. massage). We found no significant differences in mechanical effects. Although limited by the in vitro design (no blood perfusion, no metabolic compensation), the results can be used to guide operators in their choice of the best US treatment modality for a specific joint.

Incontinentia pigmenti: a rare pathology with complex rehabilitative aspects.

PURPOSE: Incontinentia pigmenti (IP), or Bloch-Sulzberger syndrome, is a rare X-linked dominant genetic disorder with multisystem involvement. To our knowledge, there are no previous reports about rehabilitation in IP adult with intact cognitive development. We report a 20-year-old lady with IP managed and followed into adulthood. METHOD: Patient management and rehabilitation programs from birth to the last follow-up. RESULTS: There was normal cognitive development despite magnetic resonance imaging (MRI) evidence of white matter, corpus callosum and brainstem hypoplasia. Extensor spasticity was present on both lower limbs for which she underwent rehabilitation from the age of one. Botulinum toxin injections were performed and when she was 15 years old she underwent functional surgery. CONCLUSION: The absence of mental retardation in our patient enabled us to carry out an active rehabilitation program and provide her with maximum independence in locomotion and in activities of daily living. IMPLICATIONS FOR REHABILIATION: Incontinentia pigmenti (Bloch-Sulzberger syndrome). Incontinentia pigmenti is a rare X-linked dominant genetic disorder with multisystemic involvement. Skin lesions, neurological impairments, motormental retardation, skeletal congenital defects and ophthalmologic involvement are IP most frequent manifestations. Due to the complex multisystem involvement resulting in severe long-term disability, patients with IP require a multidisciplinary team approach for rehabilitation. In IP patients, rehabilitation interventions should always take into consideration the individual phenotype expression, child's physical development and personal needs.

Operative Management of Sciatic Nerve Palsy due to Impingement on the Metal Cage after Total Hip Revision: Case Report.

This paper discusses a sciatic nerve palsy developed after a right total hip revision with a Burch-Schneider metal cage. A sciatalgic nerve pain appeared after surgery, while the palsy developed in about fifteen days. An electromyography showed the delay of the nerve impulse gluteal level. During the surgical exploration of the hip, a compression of the nerve on the metal cage was observed. The nerve was isolated, released from the fibrotic tissue and from the impingement, and was protected with a muscular flap. The recover from the pain was immediate, while the palsy recovered one month later.
