Abstract The AMA Guides to the Evaluation of Permanent Impairment (AMA Guides), Fifth Edition, was published in November 2000 and contains major changes from its predecessor. In the Fourth Edition, all musculoskeletal evaluation and rating was described in a single chapter. In the Fifth Edition, this information has been divided into three separate chapters: Upper Extremity (13), Lower Extremity (14), and Spine (15). This article discusses changes in the spine chapter. The Models for rating spinal impairment now are called Methods. The AMA Guides, Fifth Edition, has reverted to standard terminology for spinal regions in the Diagnosis-related estimates (DRE) Method, and both it and the Range of Motion (ROM) Method now reference cervical, thoracic, and lumbar. Also, the language requiring the use of the DRE, rather than the ROM Method has been strengthened. The biggest change in the DRE Method is that evaluation should include the treatment results. Unfortunately, the Fourth Edition's philosophy regarding when and how to rate impairment using the DRE Model led to a number of problems, including the same rating of all patients with radiculopathy despite some true differences in outcomes. The term differentiator was abandoned and replaced with clinical findings. Significant changes were made in evaluation of patients with spinal cord injuries, and evaluators should become familiar with these and other changes in the Fifth Edition.

More innovative technologies are used worldwide in patient’s rehabilitation after stroke, as it represents a significant cause of disability. The majority of the studies use a single type of therapy in therapeutic protocols. We aimed to identify if the association of virtual reality (VR) therapy and mirror therapy (MT) exercises have better outcomes in lower extremity rehabilitation in post-stroke patients compared to standard physiotherapy. Fifty-nine inpatients from 76 initially identified were included in the research. One experimental group (n = 31) received VR therapy and MT, while the control group (n = 28) received standard physiotherapy. Each group performed seventy minutes of therapy per day for ten days. Statistical analysis was performed with nonparametric tests. Wilcoxon Signed-Rank test showed that both groups registered significant differences between pre-and post-therapy clinical status for the range of motion and muscle strength (p < 0.001 and Cohen’s d between 0.324 and 0.645). Motor Fugl Meyer Lower Extremity Assessment also suggested significant differences pre-and post-therapy for both groups (p < 0.05 and Cohen’s d 0.254 for the control group and 0.685 for the experimental group). Mann-Whitney results suggested that VR and MT as a therapeutic intervention have better outcomes than standard physiotherapy in range of motion (p < 0.05, Cohen’s d 0.693), muscle strength (p < 0.05, Cohen’s d 0.924), lower extremity functionality (p < 0.05, Cohen’s d 0.984) and postural balance (p < 0.05, Cohen’s d 0.936). Our research suggests that VR therapy associated with MT may successfully substitute classic physiotherapy in lower extremity rehabilitation after stroke.

Extremity Injuries

Ankle injuries are common among young ballet dancers. These injuries may be attributed to ankle instability, insufficient lower extremity strength, and poor balance control. The purpose of this study was to explore whether these dancers exhibit functional ankle instability and if their single-leg balance control and lower extremity muscle strength correlate with functional ankle instability and leg injuries. Twenty-one ballet dancers (aged 10 to 17 years) participated in the study. The Cumberland Ankle Instability Tool (CAIT) questionnaire was used to examine functional ankle stability. Isometric muscle strength of the major lower extremity muscles was measured with a digital hand-held dynamometer. Single-leg balance was evaluated with the Y-Balance Test (YBT) and three Athletic Single-leg Stability Test (ASLST) protocols. Lower extremity injuries (self-reported) within 6 months after testing were recorded for correlation analyses. Both dominant and non-dominant ankles of the subjects exhibited functional ankle instability (26.71 and 25.71, respectively). Raising the center of mass (passé and first arm position) during the ASLST did not significantly affect balance performance (p = 0.104). However, removing extrinsic visual feedback significantly decreased single-leg balance (p < 0.001). In general, there was low correlation (r ≤ 0.49) between muscle strength, CAIT, YBT, and ASLST scores with lower extremity injuries. It is concluded that for young ballet dancers lower extremity muscle strength and single-leg balance control may not be strong contributing factors to leg injuries. This study also suggests that functional ankle stability may not have a direct impact on single-leg balance, and ballet dancers rely heavily on extrinsic visual feedback for single-leg balance control. Teachers might consider minimizing extrinsic feedback to challenge ballet dancers when implementing training protocols for single-leg balance control.

Tibial Shaft Fractures

Introduction: A tibia - fibula fracture occurs when a fall or trauma to the lower extremities puts more tension on the bones than they can tolerate. Diaphyseal tibial fractures are the most common long bone fracture. Lower extremity Tibia and fibula fractures are examples of fractures. Tibial shaft fractures are most typically associated with a history of severe trauma. The tibia is the most commonly fractured bone in the lower extremity. The bone's shaft is in the middle Fibula fractures are usually, but not always, accompanied by tibial shaft fractures. Case Presentation: At the previous 15 days, a 49-year-old male patient accounted in a hospital with a road traffic accident. Discussion: The physiotherapy was given to this patient for muscle energy technique resulting in a high degree of range of motion in the lower extremity, reduce pain, and improves flexibility and strength. Conclusion: Physiotherapy has a significant effect on pain, strength, and range of motion. The result of this case report specifies that it may be effective for pain relief, improvement in strength, and functional ability.

Receiver Operating

Context: Poor core stability is believed to increase vulnerability to uncontrolled joint displacements throughout the kinetic chain between the foot and the lumbar spine. Objective: To assess the value of preparticipation measurements as predictors of core or lower extremity strains or sprains in collegiate football players. Design: Cohort study. Setting: National Collegiate Athletic Association Division I Football Championship Subdivision football program. Patients or Other Participants: All team members who were present for a mandatory physical examination on the day before preseason practice sessions began (n = 83). Main Outcome Measure(s): Preparticipation administration of surveys to assess low back, knee, and ankle function; documentation of knee and ankle injury history; determination of body mass index; 4 different assessments of core muscle endurance; and measurement of step-test recovery heart rate. All injuries were documented throughout the preseason practice period and 11-game season. Receiver operating characteristic analysis and logistic regression analysis were used to identify dichotomized predictive factors that best discriminated injured from uninjured status. The 75th and 50th percentiles were evaluated as alternative cutpoints for dichotomization of injury predictors. Results: Players with ≥2 of 3 potentially modifiable risk factors related to core function had 2 times greater risk for injury than those with <2 factors (95% confidence interval = 1.27, 4.22), and adding a high level of exposure to game conditions increased the injury risk to 3 times greater (95% confidence interval = 1.95, 4.98). Prediction models that used the 75th and 50th percentile cutpoints yielded results that were very similar to those for the model that used receiver operating characteristic-derived cutpoints. Conclusions: Low back dysfunction and suboptimal endurance of the core musculature appear to be important modifiable football injury risk factors that can be identified on preparticipation screening. These predictors need to be assessed in a prospective manner with a larger sample of collegiate football players.
