Dramatic home videos of paralyzed Superman actor Christopher Reeve apparently using his legs are coming to television.

Reeve -- whose spinal cord was severed in a 1995 horseback riding accident -- is shown undergoing experimental treatment in which doctors put him on a special bicycle and use electrical impulses to stimulate his leg muscles into re-creating the movement of walking. 

The tape is to be shown during an ABC special, Christopher Reeve: Courageous Steps, set to air Sept. 18. 

A sit-down interview between Reeve and Barbara Walters will air on the Sept. 20 edition of 20/20

A source who has seen the tapes said the actor appears to be walking during the treatment, while the rest of the special "chronicles his progress for the past year." 

A family spokesman declined to provide details of what is in the program, and objected to the use of the term "walking." 

The show "covers what the status of his recovery is and what things he's doing in his physical rehabilitation," Reeve's spokesman, Wesley Combs, said. "But it's not accurate to say that he walks." 

Meanwhile, People magazine reports the movie Man of Steel has regained some use of his lungs -- he can breathe on his own for up to 90 minutes at a time. He can also feel a pin prick over most of his body and can distinguish between hot and cold, sharp and dull. 

He can even feel hugs from his wife, Dana. 

That progress has cost the actor $400,000 a year in medical bills, People reports. 

Reeve's doctor John McDonald said, "No one who has suffered an injury as severe as Chris', and failed to have any initial recovery, has regained the amount of motor and sensory function he has." 

Reeve said he still hopes to one day walk again, although he will miss his former goal of doing so by Sept. 25, when he turns 50. 

Nevertheless, Reeve is happy for the progress he's made. 

"To be able to feel just the lightest touch," Reeve told People. "It's really a gift."

The ABC footage of Reeve was filmed by his 21-year-old son, Matthew.

Reeve became the object of a backlash within the disabled community two years ago when he appeared in an ad for Nuveen, an investment-management company, in which he appeared to stand up an receive an award.
