The integral of 'peak perfusion' over a period of 9 minutes post exercise.

Muscle reoxygenation rate post exercise was assessed using Myoglobin Hydrogen-1 Nuclear Magnetic Resonance spectroscopy.

Muscle trophicity measured using Phosphorus 31 Nuclear Magnetic Resonance (P-31 NMR)spectroscopy and calculated based on maximum cross section of muscle (cm^2)

Developed force during the exercise bout measured using Phosphorus 31 Nuclear Magnetic Resonance (P-31 NMR)spectroscopy

Normalised work developed during the exercise was derived as Work developed during the exercise/([60 X Maximum cross section of muscle]-1100).

Normalised work measured using Phosphorus 31 Nuclear Magnetic Resonance (P-31 NMR)spectroscopy.

The metabolism efficacy index was derived as Normalised work x creatine phosphorylation rate (sec-1). [Normalised work was derived as Work developed during the exercise/(60 X Maximum cross section of muscle-1100)]. Greater values of Metabolism Efficacy index indicate improvement in skeletal muscle energetics while lower values indicate the reverse. Negative values obtained using the formula indicated severe levels of muscle weakness.

The ICARS was used to measure the general clinical symptoms of Friedreich ataxia using four subscales (i.e. Posture and gait disturbances, Kinetic functions, Speech disorders, & Oculomotor disorders). Scores for each subscale quantify the extent of ataxia in each clinically important area and subscale scores are also summed to give a total score ranging from 0 to 100, with 100 indicative of the most severely affected outcome.

The ICARS was used to measure the general clinical symptoms of Friedreich ataxia using four subscales including Posture and gait disturbances. Posture and gait disturbances score range from 0 to 34 (Higher scores indicate higher levels of impairment).

The ICARS was used to measure the general clinical symptoms of Friedreich ataxia using four subscales including Kinetic Function. Kinetic Function score range from 0 to 52 (Higher scores indicate higher levels of impairment).

The ICARS was used to measure the general clinical symptoms of Friedreich ataxia using four subscales including Speech Disorders. Speech Disorders Score range from 0 to 8 (Higher scores indicate higher levels of impairment).

The ICARS was used to measure the general clinical symptoms of Friedreich ataxia using four subscales including Oculomotor Disorders. Oculomotor Disorders score range from 0 to 6 (Higher scores indicate higher levels of impairment).

The nine hole peg test was used to assess cognitive function and in particular, fine motor coordination. The patient was asked to place nine pegs in nine holes and was scored on the amount of time it took to place and remove all nine pegs.

The choice reaction time test was used to assess cognitive functioning. On random presentation of one of six signal lights, the patient was asked to respond as quickly and accurately as possible by removing their index finger of the dominant hand from the bottom key and pressing whichever of the top six keys was indicated by the signal. Reaction time was the time elapsed between the presentation of the stimulus and the release of the finger and movement time was defined as the time elapsed between release of the finger and pressure of the second key.

The VAS used a 10-cm scoring scale in which values were reported in mm such that 0=bad and 100=good. Total score range on VAS is from 0 to 100.

Peak post exercise perfusion (mL/mn/100 g of tissue) was assessed using Arterial spin labelling combined with Nuclear Magnetic Resonance imaging.

Due to small sample size and considering there are no specific studies in this population with EGb761; calculation with the use of a statistical hypothesis was not possible. Primary efficacy analyses performed on the mITT population and analysis of safety performed on the safety population.
