Methods: A consecutive series of 107 children and young persons with traumatic brain injury (TBI) admitted to a hospital-based inpatient rehabilitation program was assessed to determine whether lower extremity spasticity could be utilized as an early clinical marker for recovery of ambulation. Presence of spasticity was determined by clinical examination at admission, and the ability to ambulate safely indoors (15.24 m) was evaluated at discharge. Sensitivity, specificity and positive and negative predictive values for spasticity were calculated.
Results: Lower extremity spasticity is a sensitive (71.4%) and specific (81.5%) predictor of the inability to ambulate at discharge. The absence of lower extremity spasticity, however, was a better predictor of ambulation recovery than the presence of spasticity was a predictor of nonambulatory status at hospital discharge.
Discussion: Implications for spasticity assessment and prognosis in terms of ambulation and recovery are discussed.

Purpose: Angioplasty of lower extremity arteries with calcification may result in flow-limiting dissection requiring bail-out stenting with unfavorable long-term outcomes. Vessel preparation prior to angioplasty may improve immediate results of the angioplasty and long-term patency. This prospective study assessed the 12-month outcomes of patients who underwent novel vessel preparation catheter, the FLEX Vessel Prep™ System (FLEX VP), prior to drug-coated balloon angioplasty (DCB-PTA).

Background: Patellofemoral pain syndrome (PFPS) is a common disorder affecting the lower extremity. This study aimed to compare the effects of functional strength training (FST) and standard strength training (SST) in PFPS patients.
Methods: Forty college students (aged 18-30 years) with PFPS and no exercise habits were randomized into FST group (n = 20) and SST group (n = 20).

Surgery is often the treatment of choice for lumbar disc herniation (LDH) with severe leg pain. This study aimed to investigate the efficacy of Condoliase chemonucleolysis (CC) in patients who were nonambulatory because of severe leg pain. A total of 58 patients who underwent CC for conservative treatment-resistant LDH were included in this study.

Ankle push-off is important for efficient, human-like walking, and many prosthetic devices mimic push-off using motors or elastic elements. The knee is extended throughout the stance phase and begins to buckle just before push-off, with timing being crucial. However, the exact mechanisms behind this buckling are still unclear.
