    Rehabilitation programs significantly improved isometric strength in injured lower limbs of workers. Gains were attributed to reduced voluntary effort and increased skill, not just muscle growth.

    Area of Science:

    • Orthopedics
    • Sports Medicine
    • Rehabilitation Science

    Background:

    • Workers with lower leg or ankle injuries often experience reduced limb strength and aerobic capacity.
    • Assessing the effectiveness of rehabilitation programs is crucial for optimizing recovery and return to work.

    Purpose of the Study:

    • To evaluate the response of injured lower extremities to a progressive rehabilitation program in a worker population.
    • To determine the changes in isometric strength, limb circumference, and tissue composition during rehabilitation.

    Main Methods:

    • Isometric strength testing of injured and contralateral limbs.
    • Measurement of thigh circumference.
    • Soft tissue radiography to assess muscle and fat tissue changes.
    • Evaluation of dynamic exercise response (lactate accumulation).

    Main Results:

    • Significant gains in isometric strength were observed within 4-6 weeks, with greater increases below the injury site (34%) than above (13%).
    • Thigh circumference showed minimal changes; radiography revealed a slight increase in muscle tissue (1%) and a decrease in subcutaneous fat (5%).
    • Dynamic exercise response remained similar pre- and post-rehabilitation, indicating subjective effort and skill as key factors in strength gains.

    Conclusions:

    • Apparent isometric strength improvements are primarily due to decreased voluntary effort and enhanced motor skill acquisition, rather than significant muscle hypertrophy.
    • Soft tissue radiography offers a more objective method for evaluating the efficacy of muscle training programs in future studies.
