Early Rehab for Muscle Injury

Rehabilitation for acute muscle injury – Early Rehab vs Delayed Rehab:

Acute muscle strains such as hamstring strains are extremely common within the sporting world. These injuries can result in substantial loss of play time and are often not rehabilitated correctly which leads to risk of recurrence.

The timing in which rehabilitation starts can significantly influence recovery from strain injuries.

What does the latest research suggest?:

In the study attached below, they investigated whether early or delayed use of injured musculotendinous tissue affected recovery after acute muscle-strain injuries.

This study found that starting rehabilitation 2 days after injury rather than waiting for 9 days shortened the interval from injury to pain-free recovery and return to sports by 3 weeks without any significant increase in the risk of re-injury.

Early loading of injured musculotendinous tissue is therefore important as a delay in rehabilitation can result in prolonged pain and a delayed return to sports, a finding that emphasizes the importance of regular and controlled mechanical loading early after trauma to large muscles

This article highlights the importance of early rehab:

Early versus Delayed Rehabilitation after Acute Muscle Injury – N Engl J Med 2017; 377:1300-1301September 28, 2017DOI: 10.1056/NEJMc1708134

Acute traumatic muscle-strain injuries are common and result in a substantial loss of time and risk of recurrence. Treatment options such as platelet-rich plasma are ineffective.1 The extent to which the timing of rehabilitation influences clinical recovery of strain injuries remains unknown. We investigated whether early or delayed use of injured musculotendinous tissue affected recovery after acute muscle-strain injuries.

We conducted a randomized, controlled trial involving 50 amateur athletes with acute injury of the thigh muscle (in approximately 60% of the patients) or calf muscle (in approximately 40%), as confirmed on ultrasonography and magnetic resonance imaging. Patients (mean age, 34 years) were recruited less than 48 hours after injury and underwent randomization to receive early therapy (2 days after injury) or delayed therapy (9 days after injury) and were followed for 12 months. The injuries were most commonly associated with playing soccer or participating in track-and-field events. (Details regarding the types of injuries are provided in the Supplementary Appendix, available with the full text of this letter at NEJM.org.)

All the patients completed a standardized four-stage therapy regimen: daily repeated static stretching (week 1), daily isometric loading with increasing load (weeks 2 to 4), dynamic loading with increasing resistance three times per week (weeks 5 to 8), and functional exercises combined with heavy strength training three times per week (weeks 9 to 12). Five patients in the early-therapy group and three in the delayed-therapy group discontinued treatment. The primary outcome was a return to sports, which was defined as the first time point of full participation in sports after being asymptomatic and successful completion of a functional test (a score of ≤1 on the Numeric Pain Rating Scale, which ranges from 0 to 10 with higher scores indicating a greater level of pain).

The interval between severe muscle injury and a return to sports was shorter in the early-therapy group than in the delayed-therapy group, with a median interval of 62.5 days (interquartile range, 48.8 to 77.8) and 83.0 days (interquartile range, 64.5 to 97.3), respectively (P=0.01)

Reinjury during the follow-up period occurred in one patient in the early-therapy group and in no patients in the delayed-therapy group. This study shows the clinical consequences of protracted immobilization after a recreational sports injury. Starting rehabilitation 2 days after injury rather than waiting for 9 days shortened the interval from injury to pain-free recovery and return to sports by 3 weeks without any significant increase in the risk of reinjury. The observed difference supports the importance of early loading of injured musculotendinous tissue. Immobilization can swiftly and adversely affect muscle and tendon structure and function and has detrimental effects on connective-tissue cells.2,3 The matrix component of muscle–tendon regeneration is substantial and prolonged,4 which may contribute to the difference in recovery time in our study. Delay in rehabilitation can result in prolonged pain and a delayed return to sports, a finding that emphasizes the importance of regular and controlled mechanical loading early after trauma to large muscles.

Physio Tullamore:

We at Physio Tullamore truly believe in combining the latest evidence with the practical skills of our practitioners. Therefore we truly believe in early loading of muscle strains and thus significantly reducing the time spent between initial injury and full return to play.
