core stability
they will receive traditional program plus functional core stability exercise
Functional core training
Participants will receive functional core motor control (stabilization) exercise and the traditional program (consisting of stretching protocol, strengthening of all ankle muscles, and balance activities) 3 sessions per week for 2 months.
strengthening exercises
Stretch the gastrocnemius and soleus muscles for 30 seconds with 3 repetitions. Strengthen all ankle muscles using TheraBand resistance for various movements (dorsiflexion, plantar flexion, inversion, and eversion) and combined movements for 3 sets of 10 repetitions, three sessions weekly for two months. The training program includes progression from seated to standing for stretching and single-limb for bipedal calf raises.
Balance training
Challenging disc training, utilized in balance studies, begins with participants standing with slightly bent knees. The dynamic balance training comprises 9 protocols focused on tracking a moving red circular target zone using a green point cursor that represents the center of pressure. Participants shift their body weight in various directions with visual feedback on a computer screen. Over 8 weeks, participants complete 16 sessions, each lasting 20 seconds with 7 seconds of rest in between. The time spent correctly tracking the target is measured and analyzed across all protocols.
Spinal motor control (stabilization) exercises
The training program consists of three phases:
1. \*\*Cognitive Phase (Weeks 1-2):\*\* Focuses on isolating the transversus abdominis and multifidus muscles using a biofeedback pressure device. Exercises involve isometric contractions with 10-second holds, repeated four times daily.
2. \*\*Associative Phase (Weeks 3-4):\*\* Introduces less stable exercises (e.g., quadruped and standing positions) aimed at enhancing spine neutrality.
3. \*\*Automatic Phase (Weeks 5-8):\*\* Involves dynamic movements that integrate spine control with extremity movements. Key exercises include lunges with a medicine ball, squats, and various plank variations, emphasizing co-contraction of core muscles for stability during movements.

Cognitive training
Balance training is combined with a cognitive task involving a backward digit span test, where participants must recall and repeat sequences of numbers in reverse order, testing working memory. This test includes three difficulty levels (3-, 4-, and 5-digit sequences) performed over 35 seconds. Participants will either recall digits while maintaining static stability or after squatting upon hearing a number, with a focus on accuracy within 5 seconds. Performance is measured by the percentage of correctly recalled digits, and error scoring will be documented via video recording for each posture task.
