Intra-Articular Injection of Botulinum Toxin for the Treatment of Knee Osteoarthritis: A Systematic Review of Randomized Controlled Trials.

The purpose of the present paper was to review the available evidence on intra-articular botulinum toxin (BTX) injection in the treatment of knee osteoarthritis and to compare it to other conservative treatment options. A systematic review of the literature was performed on the PubMed, Scopus, Cochrane Library, Web of Science, Pedro and Research Gate databases with the following inclusion criteria: (1) randomized controlled trials (RCTs), (2) written in the English language, and (3) published on indexed journals in the last 20 years (2001-2021) dealing with the use of BTX intra-articular injection for the treatment of knee OA. The risk of bias was assessed using the Cochrane Risk of Bias tool for RCTs. Nine studies involving 811 patients in total were included. Patients in the control groups received different treatments: conventional physiotherapy, hyaluronic acid injection or prolotherapy or a combination thereof in 5 studies, steroid infiltrative therapy (triamcinolone) in 1 study, placebo in 2, and local anesthetic treatment in 1 study. Looking at the quality of the available literature, two of the included studies reached "Good quality" standard, three were ranked as "Fair", and the rest were considered "Poor". No major complications or serious adverse events were reported following intra-articular BTX, which provided encouraging pain relief, improved motor function, and quality of life. Based on the available data, no clear indication emerged from the comparison of BTX with other established treatments for knee OA. The analysis of the available RCTs on BTX intra-articular injection for the treatment of knee OA revealed modest methodological quality. However, based on the data retrieved, botulinum toxin has been proven to provide good short-term outcomes, especially in patients with pain sensitization, by modulating neurotransmitter release, peripheral nociceptive transduction, and acting on the control of chronic pain from central sensitization.

Ozone Therapy versus Hyaluronic Acid Injections for Pain Relief in Patients with Knee Osteoarthritis: Preliminary Findings on Molecular and Clinical Outcomes from a Randomized Controlled Trial.

Ozone therapy (OT) is used for the treatment of multiple musculoskeletal disorders. In recent years, there has been a growing interest in its use for the treatment of osteoarthritis (OA). The aim of this double-blind randomized controlled trial was to evaluate the efficacy of OT compared with hyaluronic acid (HA) injections for pain relief in patients with knee OA. Patients with knee OA for at least three months were included and randomly assigned to receive three intra-articular injections of ozone or HA (once a week). Patients were assessed at baseline and at 1, 3, and 6 months after the injections for pain, stiffness, and function using the WOMAC LK 3.1, the NRS, and the KOOS questionnaire. Out of 55 patients assessed for eligibility, 52 participants were admitted to the study and randomly assigned into the 2 groups of treatment. During the study, eight patients dropped out. Thus, a total of 44 patients, reached the endpoint of the study at 6 months. Both Group A and B consisted of 22 patients. At 1-month follow-up after injections, both treatment groups improved statistically significantly from baseline in all outcomes measured. At 3 months, improvements remained similarly consistent for Group A and Group B. At 6-month follow-up, the outcomes were comparable between the 2 groups, showing only a worsening trend in pain. No significant differences were found between the two groups in pain scores. Both therapies have proven to be safe, with the few recorded adverse events being mild and self-limiting. OT has demonstrated similar results to HA injections, proving to be a safe approach with significant effects on pain control in patients affected by knee OA. Due to its anti-inflammatory and analgesic effects, ozone might be considered as a potential treatment for OA.

A screening test is not enough to define the prognostic role of cognitive impairment after hip fracture: a short-term prospective study.

BACKGROUND: Cognitive impairment assessed by easy-to-administer tests successfully predicts function after hip fracture, whereas the prognostic role of additional cognitive evaluations is largely unknown. AIMS: To investigate the capability of further assessments to discriminate cognitive impairment with prognostic relevance in hip-fracture women defined cognitively intact or mildly impaired on the Short Portable Mental Status Questionnaire (SPMSQ). METHODS: We prospectively investigated women with subacute hip fracture admitted to our rehabilitation facility. The women who made ≤4 errors on the SPMSQ were further assessed by 4 tests: Montreal Cognitive Assessment, Rey Auditory Verbal Learning Test (immediate and delayed recall) and Frontal Assessment Battery. Activities of daily living (ADL) were measured by the Barthel index. Successful rehabilitation was defined with a Barthel index score ≥85. RESULTS: Data from 127 women were available. Each of the 4 cognitive tests assessed at admission significantly predicted the Barthel index scores measured at discharge. The predictive role persisted after multiple adjustments. For a change in cognitive scores corresponding to the difference between 25° and 75° percentiles in their distribution in the sample, the adjusted odds ratio to achieve successful rehabilitation roughly ranged from 2 to 4, depending on which cognitive test was adopted. DISCUSSION: The women with subacute hip fracture defined cognitively intact or mildly impaired on the SPMSQ could have cognitive impairment revealed by further examination, with prognostic disadvantages in ADL. CONCLUSIONS: Assessing cognition by the SPMSQ seems not enough to exclude the presence of cognitive impairment with relevant prognostic disadvantage in hip-fracture women.

Imaging in polymyalgia rheumatica: which technique to use?

Polymyalgia rheumatica (PM) is an inflammatory rheumatic disorder characterised by pain and stiffness, mainly in the neck, shoulders, and pelvic girdle and possible association with giant cell arteritis. Currently, there is no diagnostic gold standard for PM, however, an extensive assessment of patients' inflammatory status aided by imaging evaluation is crucial for disease stratification. Many imaging techniques study PM features and their possible complications or associations with giant cell arteritis: radiography, ultrasound, scintigraphy, magnetic resonance imaging, and positron emission tomography/computed tomography. Each one has different advantages and disadvantages. The aim of this review is to clarify the current uses of imaging in PM for diagnosis and follow-up through a literature review of the last 10 years.

Effectiveness of a dance-physiotherapy combined intervention in Parkinson's disease: a randomized controlled pilot trial.

BACKGROUND: Physical therapies have been recommended as crucial components in Parkinson's disease (PD) rehabilitation. OBJECTIVE: The study aims to examine the effectiveness of a new dance-physiotherapy combined intervention, called DArT method, in mild PD patients. METHODS: A prospective, randomized, single-blind, controlled pilot trial was conducted on 38 mild PD patients under dopaminergic therapy. The intervention consisted in an add-on protocol: the control group received 1 h of conventional physiotherapy followed by 1 h of conventional physiotherapy each day, 3 times a week, for 5 weeks. The experimental group received 1 h of conventional physiotherapy followed by 1 h of dance class each day, 3 times a week, for 5 weeks. The week before and after the training period, patients were assessed for motor, cognitive, emotional, and sensory components of PD, with MDS-UPDRS-III as primary outcome measure. RESULTS: DArT method was associated with a 2.72-point reduction in the post-treatment MDS-UPDRS-III total score compared to control group (95% CI - 5.28, - 0.16, p = 0.038, d = 0.71), and with a 2.16-point reduction in the post-treatment MDS-UPDRS-III upper body subscore (95% CI - 3.56, - 0.76, p = 0.003, d = 1.02). Conversely, conventional physiotherapy program was associated with a 2.95-point reduction in the post-treatment trait anxiety compared to the experimental group (95% CI 0.19, 5.71, p = 0.037, d = 0.70). Withdrawal and fall rates were equal to 0% in both groups. CONCLUSION: DArT method showed to be safe, well accepted, and more effective than an intensive program of conventional physiotherapy in improving motor impairment in mild PD.

Spondyloarthritis: not only enthesitis.

Spondyloarthritis represents a heterogeneous group of inflammatory diseases that share common genetic, clinical and radiological features. Those diseases are characterised by inflammation in the spine and in the peripheral joints. Enthesitis is considered a pathological hallmark of the spondyloarthritis group of conditions but there are also many other relevant clinical manifestations. The aim of this article is to present an overview on articular and extra-articular manifestations and comorbidities associated with spondyloarthritis.

To Move or Not to Move? Functional Role of Ventral Premotor Cortex in Motor Monitoring During Limb Immobilization.

Anatomo-clinical evidence from motor-awareness disorders after brain-damages suggests that the premotor cortex (PMC) is involved in motor-monitoring of voluntary actions. Indeed, PMC lesions prevent patients from detecting the mismatch between intended, but not executed, movements with the paralyzed limb. This functional magnetic resonance imaging study compared, in healthy subjects, free movements against blocked movements, precluded by a cast. Cast-related corticospinal excitability changes were investigated by using transcranial magnetic stimulation. Immediately after the immobilization, when the cast prevented the execution of left-hand movements, the contralateral right (ventral) vPMC showed both increased hemodynamic activity and increased functional connectivity with the hand area in the right somatosensory cortex, suggesting a vPMC involvement in detecting the mismatch between planned and executed movements. Crucially, after 1 week of immobilization, when the motor system had likely learned that no movement could be executed and, therefore, predictions about motor consequences were changed, vPMC did not show the enhanced activity as if no incongruence has to be detected. This can be interpreted as a consequence of the plastic changes induced by long-lasting immobilization, as also proved by the cast-related corticospinal excitability modulation in our subjects. The present findings highlight the crucial role of vPMC in the anatomo-functional network generating the human motor-awareness.

Simultaneous hip and upper-limb fractures are associated with lower Geriatric Nutritional Index scores than isolated hip fractures: a cross-sectional study of 858 women.

BACKGROUND AND AIMS: Factors associated with simultaneous fractures at hip and upper limb have scarcely been investigated. Our aim was to assess the association between Geriatric Nutritional Risk Index (GNRI) scores and concurrent upper-limb fractures in women with a fall-related hip fracture. METHODS: We investigated 858 of 907 women admitted to our Physical and Rehabilitation Medicine ward following a fall-related hip fracture. RESULTS: GNRI scores were significantly lower in the 41 women with a simultaneous upper-limb fracture than in the 817 with an isolated hip fracture: median (interquartile range) were 85.9 (80.6-94.1) ad 90.3 (83.4-98.0), respectively, in the two groups (p = 0.021). After adjustment for age, height, body mass index, 25-hydroxyvitamin D, parathyroid hormone, femoral-neck bone mineral density, cognitive impairment, neurologic impairment and type of hip fracture we confirmed a significant association between GNRI scores and the concomitant upper-limb fractures (p = 0.001). The adjusted odds ratio for suffering a concomitant fracture was 7.53 (95% CI from 1.79 to 31.72; p = 0.006) for the 190 women of the GNRI lowest class (GNRI score < 82) versus the 213 women of the highest class (GNRI score > 98). CONCLUSIONS: Data show that GNRI scores were significantly lower in the subgroup of women with hip fracture and concurrent upper-extremity fracture than in the controls with isolated hip fracture. Although caution is needed in interpreting our results due to the cross-sectional design of the study, we suggest that low GNRI scores may have a role in the genesis of the concurrent fractures.

New applications of sonoelastography in rheumatology: where are we now?

Ultrasound elastography (UE) is a non-invasive imaging method that allows the assessment of tissue elastic property. Different UE techniques are currently available (i.e. strain UE and acoustic radiation force impulse UE), with several potential clinical applications. Recent studies investigated the role of UE in two systemic rheumatic diseases and psoriasis. This research added interesting information to the already known applications of UE in the assessment of tendinopathies. In SS, acoustic radiation force impulse UE has shown a potential role in the diagnosis of the disease, with lower sensitivity than and similar specificity to salivary gland histology. In SSc, a potential use of UE in screening pre-clinical disease has been reported. In psoriasis, the use of strain UE in evaluating treatment response has been highlighted. UE is a promising tool in rheumatology, with a potential role in the evaluation of various tissues and pathologies.

Is there a definition of low lean mass that captures the associated low bone mineral density? A cross-sectional study of 80 men with hip fracture.

BACKGROUND AND AIMS: Subjects with osteosarcopenia, the concurrent presence of sarcopenia and osteoporosis, have prognostic disadvantages and can benefit from treatments targeted at both the conditions. Our aim was to elucidate whether the available definitions of low appendicular lean mass (aLM) capture or not the men with associated low bone mineral density (BMD) following a hip fracture. METHODS: 80 men admitted to our rehabilitation hospital underwent a dual-energy X-ray absorptiometry scan 19.1 ± 4.1 (mean ± SD) days after hip fracture occurrence. Low aLM was identified according to either Baumgartner's definition (aLM/height2 < 7.26 kg/m2) or the criteria from the Foundation for the National Institutes of Health (FNIH): aLM < 19.75 kg, or aLM adjusted for body mass index (BMI) < 0.789. Low BMD was diagnosed with a T-score < - 2.5 at the unfractured femur. RESULTS: We found a significant positive correlation between aLM and BMD assessed at either femoral neck (r = 0.44; p < 0.001) or total hip (r = 0.50; p < 0.001). After categorization according to the FNIH threshold for aLM, we found a significant association between low aLM and low BMD: χ2(1, n = 80) = 5.4 (p = 0.020), which persisted after adjustment for age and fat mass. Conversely, categorization according to neither Baumgartner's threshold for aLM/height2 nor to the FNIH threshold for aLM/BMI was associated with low BMD. CONCLUSIONS: The association between low aLM and low BMD in men with hip fracture dramatically depends on the adopted definition of low aLM. FNIH threshold for aLM (< 19.75 kg) emerges as a useful tool to capture men with damage to both the components of the muscle-bone unit.

In Achilles tendinopathy, the neovascularization, detected by contrast-enhanced ultrasound (CEUS), is abundant but not related to symptoms.

PURPOSE AND HYPOTHESIS: Mid-portion Achilles tendinopathy is characterized by a proliferation of small vessels, called neovascularization, which can be demonstrated by power Doppler sonography (PD). Neovascularization can be correlated with diagnosis and consequent therapies focused on vascular supply. Published data regarding the relationship between neovascularisation and symptoms, such as pain and disability, are contradictory. The hypothesis that contrast-enhanced ultrasound (CEUS) could detect with more sensibility than PD the new vessel ingrowth in human degenerated Achilles tendons and therefore the correlation of neovascularization with pain and disability, was evaluated. METHODS: Thirty consecutive patients of recalcitrant Achilles tendinopathy were studied with ultrasound greyscale (US), PD, CEUS and magnetic resonance imaging. Neovascularization was recorded as percentage on the whole extension of examined area. The vascularization time was recorded as venous and arterial type. Imaging data were classified both concurrently with the examination and in a secondary blinded assessment; any difference in the subjective assessment was discussed and a consensus view formed. Pain and disability were assessed by Western Ontario McMaster Universities Arthritis Index (WOMAC) and EuroQuality of life 5-dimension-5-level questionnaire and visual analogue scale (EQ-VAS). All results were analysed with suitable statistical methods. RESULTS: 76.7% of cases were degenerated; 23.3% had also partial discontinuity of the fibres. PD detected vascularization in 54% of cases, whereas CEUS in 83% of cases: in 13 cases, PD did not detect vascularization. The vascularization time was rapid (< 20 s, arterial type) in 60% of cases. WOMAC pain mean value is 6.4 and SD 3.4; WOMAC total score mean value is 21.6 and SD 12.8. EQ-VAS mean value is 56 and SD 18.3. No statistically significant correlation emerged between vascularization and pain/disability. CONCLUSIONS: CEUS showed a greater ability to detect neovessels than PD in chronic Achilles tendinopathies. Nevertheless in 30 consecutive tendinopathies, no correlation between pain/disability and neovascularization was found: the role of multiple neovessels continue to be unclear. The possibility to discriminate arterial from venous vessels ('vascularization time') could be useful to understand the pathophysiology of tendinopathies and its healing process. STUDY TYPE: Diagnostic study. LEVEL OF EVIDENCE: II.

The presence and influence of mild depressive symptoms on post-operative pain perception following primary total knee arthroplasty.

PURPOSE: To evaluate the influence of mild depression on pain perception after total knee arthroplasty (TKA). METHODS: Hamilton depression (HDRS) and numeric rating (NRS) scales were used to evaluate depression severity and pain perception at various intervals surrounding TKA. The Hospital for Special Surgery (HSS) knee and pain scores (NRS) in patients with signs of mild depression (HDRS < 20 points) were compared to a control group of patients with no signs of depression (HDRS < 8 points). RESULTS: Prior to surgery, there were no statistical differences in pain perception (NRS) or individual components of HSS knee score including range of motion, pain, and function between patients with mild depression compared to controls. However, following surgery, patients with signs of mild depression were more likely to report more pain (p < 0.001) and have lower HSS scores even at 1 year post-operatively (p < 0.001). CONCLUSIONS: A significant number of patients in this series undergoing routine primary TKA had signs of subclinical depression. These patients are more likely to report increased pain even at 1 year following surgery compared to patients without signs of depression preoperatively. Psychometric evaluation prior to surgery can help identify the at-risk patient and allow for proper management of patient expectations, thus improving clinical results and patients' satisfaction after TKA. LEVEL OF EVIDENCE: Prospective comparative study, II.

The rehabilitative effects on written language of a combined language and parietal dual-tDCS treatment in a stroke case.

In this paper we report the effect of a combined transcranial direct current stimulation (tDCS) and speech language therapy on linguistic deficits following left brain damage in a stroke case. We show that simultaneous electrical excitatory stimulation to the left and inhibitory stimulation to the right parietal regions (dual-tDCS) affected writing and reading rehabilitation, enhancing speech therapy outcomes. The results of a comparison with healthy controls showed that application of dual-tDCS could improve, in particular, sub-lexical transcoding and, specifically, the reading of non-words with increasing length and complexity. Positive repercussions on patient's quality of functional communication were also ascertained. Significant changes were also found in other language and cognitive tasks not directly treated (comprehension and constructive apraxia).

Instrumented gait analysis for an objective pre-/postassessment of tap test in normal pressure hydrocephalus.

OBJECTIVE: To present an objective method to evaluate gait improvements after a tap test in idiopathic normal pressure hydrocephalus (INPH). DESIGN: Retrospective analysis of gait data. SETTING: Public tertiary care center, day hospital. The gait analysis was performed before and 2 to 4 hours after the tap test. PARTICIPANTS: Participants included patients with INPH (n=60) and age- and sex-matched controls (n=50; used to obtain reference intervals). From an initial referred sample of 79 patients (N=79), we excluded those unable to walk without walking aids (n=9) and those with incomplete (pre-/posttap test) gait data (n=10). Thirteen out of 60 patients were shunted and then reappraised after 6 months. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Mahalanobis distance from controls, before and after the tap test. Eleven gait parameters were combined in a single quantitative score. Walking velocity was also evaluated because it is frequently used in tap test assessment. RESULTS: Patients were classified into 2 groups: tap test responders (n=22, 9 of them were shunted) and not suitable for shunt (n=38, 4 of them were shunted). In the tap test responders group, 9 out of 9 patients improved after shunt. In the not suitable for shunt group, 3 out of 4 patients did not improve. Gait velocity increased after the tap test in 53% of responders and in 37% of patients not suitable for shunt. CONCLUSIONS: The new method is applicable to clinical practice and allows for selecting tap test responders in an objective way, quantifying the improvements. Our results suggest that gait velocity alone is not sufficient to reliably assess tap test effects.

Does texting while walking really affect gait in young adults?

BACKGROUND: Texting on a smartphone while walking has become a customary task among young adults. In recent literature many safety concerns on distracted walking have been raised. It is often hypothesized that the allocation of attentional resources toward a secondary task can influence dynamic stability. In the double task of walking and texting it was found that gait speed is reduced, but there is scarce evidence of a modified motor control strategy compromising stability. The aim of this study is twofold: 1) to comprehensively examine the gait modifications occurring when texting while walking, including the study of the lower limb muscle activation patterns, 2) to specifically assess the co-contraction of ankle antagonist muscles. We hypothesized that texting while walking increases co-contractions of ankle antagonist muscles when the body weight is transferred from one lower limb to the other, to improve the distal motor control and joint stabilization. METHODS: From the gait data collected during an instrumented walk lasting 3 min, we calculated the spatio-temporal parameters, the ankle and knee kinematics, the muscle activation patterns of tibialis anterior, gastrocnemius lateralis, peroneus longus, rectus femoris, and lateral hamstrings, and the co-contraction (occurrence and duration) of the ankle antagonist muscles (tibialis anterior and gastrocnemius lateralis), bilaterally. RESULTS: Young adults showed, overall, small gait modifications that could be mainly ascribable to gait speed reduction and a modified body posture due to phone handling. We found no significant alterations of ankle and knee kinematics and a slightly delayed activation onset of the left gastrocnemius lateralis. However, we found an increased co-contraction of tibialis anterior and gastrocnemius lateralis, especially during mid-stance. Conversely, we found a reduced co-contraction during terminal stance. CONCLUSIONS: Our results suggest that, in young adults, there is an adjustment of the motor control strategy aimed at increasing ankle joint stability in a specific and "critical" phase of the gait cycle, when the body weight is transferred from one leg to the other.

Multimodal Analgesia in Total Knee Arthroplasty: A Randomized, Double-Blind, Controlled Trial on Additional Efficacy of Periarticular Anesthesia.

Pain management is a main determinant of functional recovery after total knee arthroplasty (TKA). We performed a randomized, controlled, double blind study to evaluate additive efficacy of periarticular anesthesia in patients undergoing TKA in reducing post-operative pain, operated limb edema and improving post-operative mobility. Patients were randomly assigned to study or control group; all subjects received the same analgesic protocol; before wound closure, the study group received also a periarticular anesthesia (ropivacaine 1% 20 mL). The results show no statistical differences in any of the variable evaluated. Our data suggest that additive periarticular anesthetic protocol with ropivacaine 1% 20 mL is not superior to oral and intravenous analgesia alone in patients undergoing TKA, regarding post-operative pain control, operated limb edema reduction and post-operative mobility improvement.

NexGen® LPS mobile bearing total knee arthroplasty: 10-year results.

PURPOSE: Mobile bearing (MB) knee prostheses were designed to improve the performances of the total knee arthroplasties (TKA). The clinical superiority of MB prosthesis compared to its fixed bearing counterpart has remained elusive. This study prospectively evaluates the cumulative survivorship, clinical, radiographic results, and complications of a large series of MB TKAs in relation to patient age, sex, severity of arthritis, and patellar resurfacing. METHODS: This study evaluates the 5- to 10-year cumulative survival rate of the NexGen(®) LPS MB. Between 2000 and 2005, we performed a consecutive series of 332 MB, posterior-stabilized TKA in 249 patients (mean age 71.2 years, SD 6.9). The implants were clinically evaluated with the Hospital Special Surgery Knee Score (HSS-KS) and radiographically with the Knee Society Roentgenographic Evaluation System (KS-RES). The mean follow-up was 76.3 months (minimum 5 years). RESULTS: The HSS-KS improved from 55 pre-operatively to 86 at the end of follow-up. According to the KS-RES, the implants were anatomically aligned and progressive radiolucent lines appeared in four knees (1.2 %). The patella was selectively resurfaced in 162 of 332 knees. Patients with the patella resurfaced had better clinical results compared to those not resurfaced, but there was no difference in terms of survival. The cumulative survival rate was 98.4 % at 10 years (Kaplan-Meier's analysis). CONCLUSIONS: This MB implant provided reliable and durable clinical results with a survivorship of over 98 % at 10 years, in unselected patients regardless of age, sex, severity of disease, and patellar treatment.

Cognitive assessment to optimize prediction of functional outcome in subacute hip fracture: a short-term prospective study.

BACKGROUND: Cognitive impairment is a long-known negative prognostic factor after hip fracture. Cognition is usually screened by a single easy-to-administer bedside tool, but recent studies have shown that screening tests may be not enough to rule out cognitive impairment with an unfavorable prognostic role. Unfortunately, data on outcome prediction by further cognitive assessments is sparse. AIM: We focused on patients with subacute hip fracture defined cognitively intact or mildly impaired on the screening evaluation performed by the Short Portable Mental Status Questionnaire (SPMSQ). We hypothesized that each of 3 further cognitive tests could independently predict activities of daily living, with optimal prediction of function obtained by performing all three the tests. DESIGN: Short-term prospective study. SETTING: Rehabilitation ward. POPULATION: Inpatients with subacute hip-fracture. METHODS: Three cognitive tests were performed on admission to rehabilitation in the patients who made ≤4 errors on the SPMSQ: Montreal Cognitive Assessment (MoCA), Rey Auditory Verbal Learning Test (RAVLT, immediate and delayed recall) and Frontal Assessment Battery (FAB). We assessed activities of daily living by the Barthel index. Successful rehabilitation was defined with a Barthel Index Score ≥85. RESULTS: Each of the three cognitive tests assessed before rehabilitation significantly predicted the Barthel index scores measured at the end of the rehabilitation course in our sample of 280 inpatients. However, only the MoCA score retained its significant predictive role when the scores from the three tests were included together as independent variables in a multiple regression model, with adjustments for a panel of potential confounders (P=0.007). The adjusted odds ratio to achieve successful rehabilitation for a seven-point change in MoCA score was 1.98 (CI 95% from 1.02 to 3.83; P=0.042). CONCLUSIONS: Contrary to our hypothesis, MoCA but not RAVLT and FAB retained the prognostic role when the scores from the three tests were evaluated together as potential predictors of functional ability in activities of daily living. CLINICAL REHABILITATION IMPACT: In the presence of a normal (or mildly altered) score on the SPMSQ in subacute hip fracture, MoCA scores improve prediction of activities of daily living and should be routinely performed.

Adductor longus and brevis lesion in an amateur soccer player: platelet rich plasma and multifractioned hyaluronic acid injections to enhance clinical recovery.

Groin pain is a common issue in athletes, with a particularly high incidence in male soccer players. Adductor muscles are the most involved site of the groin, accounting for up to one-fourth of muscle injuries of that region. Physical therapy and rehabilitation programs for adductor-related groin pain using active exercises are effective in getting athletes back to sport. However, the return-to-play time varies according to the injury severity. Minor lesions can recover in 1-2 weeks, while severer injuries require 8-12 weeks. To enhance tendon healing and shorten the return to play time, intrandentinous injections of Platelet Rich Plasma (PRP) have been proposed. An increasing body of evidence in literature have shown efficacy of platelet rich plasma in aiding the healing process in tendinopathies. Similarly, more recent evidences have proven hyaluronic (HA) acid to have anti-inflammatory, proliferative, repairing, and analgesic effects. This case report presents the clinical application of combined PRP and a multifractioned (a mixture of different molecular weights) HA in a 24-year-old athlete suffering from a hip adductor rupture.

Longitudinal Assessment of Botulinum Toxin Treatment for Lateral Trunk Flexion and Pisa Syndrome in Parkinson's Disease: Real-life, Long-Term Study.

Lateral trunk flexion (LTF) and its severe form, called Pisa syndrome (PS), are highly invalidating axial postural abnormalities associated with Parkinson's disease (PD). Management strategies for LTF lack strong scientific evidence. We present a real-life, longitudinal study evaluating long-term efficacy of botulinum toxin (BoNT) injections in axial muscles to reduce LTF and PS in PD. A total of 13 PD patients with LTF > 5° received ultrasound- and electromyography-guided BoNT injections every 4 months. Seven untreated matched PD patients with LTF served as controls and their changes in posture after 18 months were compared with those of seven patients continuing BoNT over 12 months. 53.8% of patients continued the BoNT injections for at least 12 months. Various individual LTF responses were observed. Overall, BoNT-treated patients obtained a not statistically significant improvement of LTF of 17 ± 41% (p = 0.237). In comparison, the seven untreated PD patients suffered a deterioration in LTF over 12 months by 36 ± 45% (p = 0.116), showing a significantly different trajectory of posture change (p = 0.026). In conclusion, repeated BoNT injections in axial muscles showed varying effects in managing PD-associated LTF, suggesting that: (a) a relevant number of patients with LTF can benefit from BoNT; (b) long-term treatment could prevent LTF worsening; (c) an instrumented, personalized approach is important; and (d) there is a need for prospective, long-term studies.
