Muscle injuries are the most common trauma in team and individual sports. The muscles most frequently affected are those of the lower limb, and in particular hamstrings, adductors, rectus femoris and calf muscles. Although several scientific studies have tried to propose different rehabilitation protocols, still too often the real rehabilitation process is not based on scientific knowledge, especially in non-elite athletes. Moreover, the growing use of physical and instrumental therapies has made it increasingly difficult to understand what can be truly effective. Therefore, the aim of the present paper is to review proposed therapeutic algorithms for muscle injuries, proposing a concise and practical summary. Following a three-phase rehabilitation protocol, this review aims to describe the conservative treatment of indirect structural muscle injuries, which are the more routinely found and more challenging type. For each phase, until return to training and return to sport are completed, the functional goal, the most appropriate practitioner, and the best possible treatment according to current evidence are expressed. Finally, the last section is focused on the specific exercise rehabilitation for the four main muscle groups with a structured explanatory timetable.

Background: Postural stability and plantar pressure parameters can be assessed by baropodometry; nevertheless, they are often affected by low repeatability. The aim of the study was to test the accuracy and repeatability of a novel resistive sensor pressure plate and to establish the most reliable baropodometric parameters. Methods: Accuracy and repeatability of the FM12050 BTS-Bioengineering plate measurements were assessed by using different weights in static conditions across three sessions. Subsequently, 20 healthy subjects were assessed by 30-s stabilometric analysis in bipedal standing with open eyes across four trials in two sessions, morning and afternoon. Results: Pressure plate repeatability in measuring the static weights was very high, and plate measurements were correlated to the scale measurements (Pearson’s coefficient = 0.99). Percentage of load distribution between left and right foot and in rearfoot and forefoot regions showed the largest repeatability (coefficient of variation < 5%) across trials. Eventually, median and percentiles (25–75%) were reported for each parameter. Conclusions: This study helped to assess the accuracy and repeatability of a novel pressure plate in static conditions and to define the most reliable parameters for the assessment of postural stability and foot morphology. The present healthy-subject stabilometric dataset may be used as reference data in the evaluation of pathological populations.

Background: Late Onset Pompe Disease(LOPD) is a rare myopathy characterized by prevailing weakness of trunk and pelvic girdle muscles that causes motor disabilities. Spinal deformities have been reported unclearly on clinical examination. No study quantitatively assessed upright posture defining specific alterations of LOPD various phenotype. Objective: Identify postural abnormalities in a homogeneous group of LOPD patients using 3D-Stereophotogrammetry(St) and x-Ray(xR). Methods: Seven LOPD siblings were recruited. They were assessed by clinical scales and, in upright posture, using xR and 3D-St with a new marker set protocol. Fourteen healthy individuals, age and sex-matched, were used as controls for St-parameters; normative xR-values were found in literature. Results: LOPD patients showed a significant weakness of trunk and tibialis anterior muscles. Statistical analysis of St-parameters showed a larger ankle, knee, elbow, dorsal, S2-C7, heel-S2-C7, heel-S2-nasion angles and a lower sagittal vertical axis(SVA) than controls. xR-analysis highlighted an absence of scoliosis and a lower occipito-cervical, C2-C7 cervical and Cobb dorsal angles, and a trend to lower lumbar lordosis and SVA compared to normal values. Significant correlation was found in dorsal and lumbar angles calculated using xR-markers placed on spiny apophysis, xR-centre of vertebral bodies, Cobb-method and St-markers. Conclusion: This is the first quantitative study of postural abnormalities in LOPD patients using 3D-St and xR, highlighting sagittal standing alignment changes,difficult to assess to direct exam.Our new St-protocol showed a high reliability compared to xR. Further studies on larger population of LOPD might confirm the usefulness of these instrumental methods for monitoring disease course.
