Characteristics of studies included.

1. Range of age in years.2. 9–10 min warm-up exercises followed by 3–4 min flexibility exercises. Strength exercises for arms, back and abdomen were then done on all fours, and prone and supine, for 6–7 min. This was followed by balance exercises in standing for 3–4 min.

An X RM is the weight a person can lift X times at a steady controlled pace through the full range of joint motion.4. MVIC, maximum voluntary isokinetic strength.5. Between these two sets of dynamic exercises patients performed a 30-second isometric exercise with the same training weight.
