Early Active Motion (EAM) Protocols: Multi-Strand Core Suture Repairs

Over the past two decades, hand surgery has undergone a paradigm shift from passive mobilization protocols toward Early Active Motion (EAM). Pioneered by surgical groups in Belfast, Indianapolis, and across Europe, EAM relies on robust multi-strand core suture techniques that provide sufficient biomechanical strength to withstand controlled active muscle contractions during the earliest stages of healing. By utilizing four-strand, six-strand, or eight-strand core sutures (such as Adelaide, Strickland, or Savage techniques) paired with a continuous running epitendinous suture, surgeons can construct repairs capable of handling 35 to 60 Newtons of tensile force, creating a wide safety margin for early active place-and-hold exercises.

In India, early functional recovery is an economic necessity for millions of self-employed artisans, daily wage workers, and agriculturalists who cannot afford months of hand disability. A roadside fruit seller in Bangalore, a bangle maker in Firozabad, or a diamond polisher in Surat needs rapid return of hand dexterity to maintain their household income. EAM protocols significantly shorten total recovery time, reduce the incidence of secondary joint contractures, and accelerate the transition back to work. However, because EAM involves active muscle firing, clinicians must maintain strict supervisory control to prevent patients from overestimating their strength and lifting heavy items prematurely.

The biomechanical rationale for EAM centers on intrinsic tendon healing and tissue gliding resistance. During passive motion, proximal tendon excursion is driven solely by distal joint push, which can cause subtle buckling of the repair site against the pulley margins. In contrast, active muscle contraction exerts direct proximal pull on the tendon, drawing it cleanly through the sheath without accordion-like folding. Furthermore, active tension stimulates mechanotransduction pathways in tenocytes, upregulating collagen synthesis, enhancing tensile strength gain, and promoting faster maturation from weak Type III to sturdy Type I collagen fibrils. Gliding resistance within the fibro-osseous canal drops precipitously when early active motion prevents peritendinous fibrin webs from forming.

EAM is initiated within 3 to 5 days post-surgery, once acute postoperative inflammatory edema begins to stabilize. The hallmark exercise is the place-and-hold maneuver. The therapist or patient passively curls the fingers into partial or mid-range composite flexion, and the patient then gently fires their flexor muscles with just enough isometric effort to maintain the finger position for 3 to 5 seconds before releasing. True unassisted active flexion through a full arc is introduced gradually around weeks 3 to 4, depending on the suture construct. Throughout this period, a dorsal blocking splint or Manchester short splint protects the hand against accidental extreme extension.
