Concussion Physical Therapy: How Athletes Recover and Return to Sport

Concussions are one of the most misunderstood injuries in sport, resulting in a variety of symptoms, impaired coordination and athletic performance. For years, the standard advice was simple: rest from activities until symptoms go away, then gradually return to play. In other words: rest is best.

We now know that approach is incomplete and lacks evidence based support, and in many cases delays recovery for our athletes.

At The Performance Shift, we take a different approach: one rooted in early active rehabilitation, objective testing, and individualized return-to-sport progression. Sports physical therapy plays a critical role in both acute and chronic concussion management, helping athletes recover faster, reduce risk of reinjury, and return to sport with confidence.

The Problem with “Just Rest”

Historically, athletes were prescribed prolonged physical and cognitive rest after a concussion. While initial short-term rest (24 to 72 hours) is still recommended to allow the brain to heal, research consistently shows that extended rest beyond that window may actually slow recovery and contribute to persistent symptoms. Athletes that rest too long may have lower mood, higher anxiety and delayed reaction time (Moser & Schatz, 2012).

Recent evidence supports a shift toward early, controlled, sub-symptom activity such as riding a stationary bike, or walking at a prescribed intensity for 10 to 20 min/day. Active rehabilitation, when appropriately guided, has been shown to improve recovery timelines and reduce the likelihood of prolonged symptoms (Patricios et al., 2023).

Why Sports Physical Therapy Matters

Sports-related concussion is a traumatic brain injury, they affect multiple systems:

• Vestibular (balance, dizziness)
• Ocular (vision, tracking)
• Cervical spine (neck pain, headaches)
• Autonomic nervous system (heart rate, exercise tolerance)

This is where sports physical therapy becomes essential at recognizing sports-related concussion on the sideline or through clinical assessment, preventing persistent symptoms and risk of recurrent injury, and helping with the transition to return to sport and learning (Patricios et al., 2022).

A comprehensive PT evaluation identifies which systems are still impaired, allowing us to build a targeted plan instead of waiting passively for symptoms to resolve. We additionally take this time to assess what other impairments athletes may have or compensation patterns to reduce a secondary concussion or lower extremity injury like an ACL tear or ankle sprain.

Research shows that targeted interventions, such as vestibular, cervical strengthening, dual task and reaction time training, can accelerate recovery and improve return-to-sport outcomes, particularly in athletes with prolonged symptoms (Barnes et al., 2024).

Active Rehabilitation: The Game Changer

Two of the most important advancements in concussion care is the use of early graded aerobic exercise and integration of reaction time testing with dual task training (Barnes et al., 2024).

Instead of avoiding activity, we now:

• Identify an athlete’s symptom threshold
• Prescribe aerobic exercise below that threshold
• Progress intensity as tolerance improves to get back to sports-related activities

This approach helps restore:

• Autonomic regulation
• Exercise tolerance
• Blood flow to the brain

Clinical protocols emphasize that rehabilitation should be both time-based and criteria-based, adapting to the athlete’s individual response with graded exposure rather than following a rigid timeline for return to play.

The Role of PT in Return-to-Sport Decision Making

The widely accepted 6-step return-to-play progression completed by the PT and athletic trainer ensures that athletes only advance when they are symptom-free at each stage.

However, symptom resolution alone is not enough.

At The Performance Shift, we go beyond symptoms and assess:

• Strength and power asymmetries
• Neuromuscular control
• Reaction time and coordination
• Balance and force production — see how we use VALD ForceDecks data to guide return-to-sport decisions

Why does this matter?

Because research shows that athletes returning from concussion are at increased risk for musculoskeletal injury, likely due to lingering neuromotor deficits (Howell et al., 2022), so we make sure to assess movement quality as part of return to play.

Acute vs. Chronic Concussion: How PT Helps Both

Acute Concussion (0 to 4 weeks)

Sports PT focuses on:

• Early symptom-guided activity
• Cervical and vestibular assessment
• Aerobic exercise prescription
• Preventing deconditioning

This early intervention can shorten recovery time and improve progression through return-to-play stages.

Chronic / Persistent Symptoms (> 4 weeks)

For athletes with lingering symptoms, PT becomes even more critical.

Targeted rehab may include:

• Vestibular therapy for dizziness and motion sensitivity
• Vision therapy integration
• Cervical spine treatment for headaches
• Progressive strength and conditioning

The Multidisciplinary Advantage

The best outcomes happen when concussion care is integrated.

At TPS, this means collaboration between:

• Sports physical therapists
• Strength & conditioning coaches
• Sports psychologists
• Medical providers

Concussion recovery is not linear and having a team allows us to adapt in real time, ensuring no system is overlooked. We prioritize communication with the athlete, family, coach, ATC and remainder of the sports medicine team.

The Bottom Line

Concussion management has evolved—and so should the way we treat it.

Sports physical therapy:

• Speeds up recovery through active rehabilitation
• Identifies and treats underlying impairments
• Reduces risk of reinjury
• Ensures a safe, confident return to sport

The goal isn’t just to “feel better.” It’s to return better and prevent the likelihood of an athlete being sidelined by a future injury.
