Definition / Description[edit | edit source]
Muscle strength is the amount of force a muscle can generate. The ability to generate force is necessary for all types of movement.
Regaining strength bilaterally is accepted clinical practice and is thought to be important for the prevention of ligamentous injuries at the ankle.
Charecteristics[edit | edit source]
Muscle fiber cross-sectional area (CSA) is positively related to maximal force production. The arrangement of fibers according to their angle of pennation, muscle length, joint angle, and contraction velocity can alter the expression of muscular strength. Force generation is further dependent upon motor unit activation according to the size principle.
Adaptations to resistance training enable greater force generation through numerous neuromuscular mechanisms. Muscle strength may increase significantly within the first week of training, and long-term strength enhancement manifests itself through enhanced neural function(e.g., greater recruitment, rate of discharge), increased muscle CSA, changes in muscle architecture, and possible adaptations to increased metabolites, for increased strength.
The magnitude of strength enhancement is dependent on the type of program used and the careful prescription of muscle actions, intensity, volume, exercise selection and order, rest periods between sets, and frequency.
Physical Therapy Management[edit | edit source]
Once ROM is achieved and swelling and pain are controlled, the patient is ready to progress to the strengthening phase of rehabilitation. (2 ,3) Strengthening of weakened muscles is essential to rapid recovery and is a preventive measure against reinjury. All muscles of the ankle should be targeted, including the peroneal muscles. All exercises performed bilaterally.
Continual monitoring of strength is important. Isokinetic strength testing is an accepted method of assessing ankle strength. Also used is a hand-held dynamometry for consistent monitoring of strength performance. (ref 1 level A1)
It is important to understand that each rehabilitation program must be individualized (ref 2)
The use of mental practise during the threatment also results in higher strength gain (ref 5 level A2?)
