The foot intrinsic muscles are increasingly targeted in foot and ankle rehabilitation. The
exercises are often difficult to learn initially. The purpose of the proposed study is to
examine the effect training the intrinsic foot muscles on performance in selected physical
and functional measures such as balance, plantar pressure during gait, vertical jump, and
foot posture. In addition,the investigators will compare one group training with traditional
exercise instruction methods and one group using an adjunctive modality (neuromuscular
electric stimulation) during the introductory phases of exercise instruction. The
investigators are interested in how this modality might affect physical and functional
outcome measures and if it affects participants' frustration with learning a new exercise.

Arm 1: The purpose of this arm of the study is to determine if a 4-week trial of foot muscle
exercises, instructed with passive, active-assisted, and active techniques, affect functional
measures such as balance, plantar pressure during gait, and vertical jump. A frustration
index will be employed to assess participant frustration with learning a new exercise. 15
will be enrolled in this arm of the study.

Arm 2: The purpose of this arm of the study is to determine if a 4-week trial of foot muscle
exercises, instructed with neuromuscular electric stimulation (NMES) and active techniques,
affect functional measures such as balance, plantar pressure during gait, and vertical jump.
A frustration index will be employed to assess participant frustration with learning a new
exercise.15 will be enrolled in this arm of the study.

Arm 3: This group will not engage in any training, but will serve as a comparator for the two
intervention arms.

Inclusion Criteria:

- Individuals aged 18-30; Participate in physical activity 3 times/week; No neurologic
injury/condition; No prior experience with study exercises; No injury to lower
extremity in past 2 months; Inability to selectively extend the great toe while the
lesser toes remain quiet (indicating INTRINSIC FOOT MUSCLES dysfunction)

Exclusion Criteria:

- Sedentary; Known neurologic injury or condition; Current LE injury that may affect
neuromuscular function; Tarsal coalition; Absolute contradiction to manual therapy or
neuromuscular electrical stimulation (NMES); Previous intrinsic foot muscle training
