original publication.
Questo studio è stato identificato come potenzialmente ad alto impatto.
La metrica High Impact di OE, guidata dall'AI, stima l'influenza che un articolo potrebbe avere integrando i segnali della rivista in cui è stato pubblicato e il contenuto scientifico dell'articolo stesso.
Sviluppato utilizzando un'elaborazione del linguaggio naturale all'avanguardia, il modello High Impact di OE prevede in modo più accurato la futura performance citazionale di uno studio rispetto al solo fattore di impatto della rivista.
Ciò consente di riconoscere prima le ricerche clinicamente significative e aiuta i lettori a concentrarsi sugli articoli che hanno maggiori probabilità di influenzare la pratica futura.

22 young athletes with grade I or II unilateral inversion ankle sprain within 3 weeks of injury were randomized to plyometric training or resistive training for 6 week duration. At 6 week follow up, the plyometric rehabilitation following an acute ankle sprain resulted in significantly better functional performance than using resistive training alone.
Was the allocation sequence adequately generated?
Was allocation adequately concealed?
Blinding Treatment Providers: Was knowledge of the allocated interventions adequately prevented?
Blinding Outcome Assessors: Was knowledge of the allocated interventions adequately prevented?
Blinding Patients: Was knowledge of the allocated interventions adequately prevented?
Was loss to follow-up (missing outcome data) infrequent?
Are reports of the study free of suggestion of selective outcome reporting?
Were outcomes objective, patient-important and assessed in a manner to limit bias (ie. duplicate assessors, Independent assessors)?
Was the sample size sufficiently large to assure a balance of prognosis and sufficiently large number of outcome events?
Was investigator expertise/experience with both treatment and control techniques likely the same (ie.were criteria for surgeon participation/expertise provided)?
Sì = 1
Incerto = 0,5

L'Indice di Fragilità è uno strumento che aiuta l'interpretazione dei risultati significativi, fornendo una misura della forza di un risultato. L'Indice di Fragilità rappresenta il numero di eventi consecutivi che devono essere aggiunti a un risultato dicotomico per rendere il risultato non più significativo. Un numero piccolo rappresenta un risultato più debole, mentre un numero grande rappresenta un risultato più forte.
Perché questo studio era necessario ora?
Ankle sprain is an extremely common form of injury leading to physical disability. Plyometric training has been widely applied to improve performance in healthy athletes and is also highly recommended in the later part of rehabilitation after lower limb injuries. After an exhaustive literature search, the authors determined that although the effectiveness of plyometric exercise has been extensively studied, its applicability in acute ankle sprain rehabilitation is yet unknown.
Qual era la domanda di ricerca principale?
Does a 6-week plyometric therapy offer superior functional and muscle strength improvement than resistive training in athletes with a lateral ankle sprain?
- Both groups significantly improved at the end of the 6-week intervention in all 4 functional tests (climbing down stairs, number of heel and toe raises, and single-limb stance tests) from baseline (all p<0.001).
- The plyometric group displayed significantly greater improvements than the resistive group for all functional tests (p<0.05).
- After 6 weeks, both the resistive exercise and plyometric groups had significantly increased peak torque for evertors and invertors compared to body weight at both 30 and 120 degrees/second, when compared to baseline (p<0.05).
- There was no significant difference in the improvements in peak torque for evertors and invertors compared to body weight between groups (p>0.05).
Che cosa devo ricordare di più?
There was no significant differences in the peak torque of the ankle evertors or invertors; however, the overall functional performance following the plyometric training was significantly better than the resistance training.
Come influenzerà l'assistenza ai miei pazienti?
This study supports the use of plyometric training following acute ankle sprains. Muscle strength improvements were similar in both groups; however, functional performance was significantly improved in the plyometric group. The authors indicate that rehabilitation therapy took place 3 weeks following the injury.
